ABSTRACT
Background: Several studies described occurrence of myocarditis after SARS-CoV-2 vaccination in pediatric patients. Weaimed to characterize the clinical course of myocarditis following SARS-CoV2 vaccination including follow-up data within the prospective German registry for suspected myocarditis in children and adolescents "MYKKE." Method: Patients younger than 18 years with suspected myocarditis and onset of symptoms within 21 days followingSARS-CoV2 vaccination were enrolled within the MYKKE registry. The suspect of myocarditis is valid in patients with clinical symptoms and diagnostic findings typically seen in myocarditis. Clinical data are monitored at initial admission and duringshort-term and long-term follow-up. Result(s): Between July 2021 and August 2022, a total of 48 patients with a median age of 16.2 years (IQR: 15.2-16.8)were enrolled by 13 centers, 88% male. Onset of symptoms occurred at a median of 3 days (IQR: 2-7) after vaccine administration, most frequently after the second dose (52%). Most common symptoms at initial admission were anginapectoris (81%), fatigue (56%), dyspnea (24%) and documented arrhythmias (17%). Initial ECG abnormalities included ST-elevation (48%) and T-wave inversion (23%). Elevated Tropon in was observed in 32 patients (67%) and in 19 cases (40%)NT-proBNP was above the normal range with a median level of 171 pg/mL (IQR: 32-501). 11 (23%) patients presentedwith mildly reduced systolic function at initial echocardiography or cardiac MRI. In 40 patients cardiac MRI and/orendomyocardial biopsy was performed (83%) and diagnosis of myocarditis could be verified in 27 cases (68%). Thirty-nine patients underwent short-term follow-up with a median of 2.8 months (IQR: 1.9-3.9) after discharge. 19 patients (49%)presented with either clinical symptoms (n = 9) and/or diagnostic abnormalities (n = 16) at follow-up. 12 patients (38%)still had medical treatment. Except for one patient with malign arrhythmias (ventricular tachycardia), no major cardiac adverse events were observed during initial admission and follow-up. Conclusion(s): Our data confirm that SARS-CoV-2 vaccine-related myocarditis is characterized by a mild disease course. However, after short-term follow-up a considerable number of patients still presented with symptoms and/or diagnostic abnormalities. Data on long-term follow-up are awaited.
ABSTRACT
Background: Takotsubo cardiomyopathy is characterized by left ventricular dysfunction with apical ballooning in the absence of significant coronary artery disease. Though rare in pregnancy, this transient cardiac dysfunction may affect women in antepartum, intrapartum, or postpartum period, making it difficult to discern the inciting event or differentiate from spontaneous coronary artery dissection or peripartum cardiomyopathy. Most patients respond well to medical management with spontaneous resolution of cardiac dysfunction within weeks of diagnosis. Case presentation: A 38-year-old female G3P0202 at 36 weeks of gestation with a history of preeclampsia, hypertension, hyperlipidemia, and recent COVID-19 infection presented with severe substernal chest pain. She was hypertensive on arrival with a blood pressure of 220/120 mm Hg. Electrocardiogram showed T-wave inversion in the anterior leads and troponin I level was 2.6 ng/ml. She was treated with aspirin 324 mg, IV hydralazine 20 mg, IV magnesium sulfate infusion for seizure prophylaxis and fetal neuroprotection. A transthoracic echocardiogram revealed left ventricular ejection fraction of 35-40% with apical ballooning. Urgent left heart catheterization did not show signs of epicardial coronary artery disease, prompting the diagnosis of Takotsubo cardiomyopathy. Hospital course included interdisciplinary team-based medical therapy until cesarean section 24 hours after arrival. Following delivery, she was started on guideline directed medical therapy for heart failure and discharged home. At her one month follow-up, she was still experiencing symptoms of heart failure and classified as New York Heart Association Class II. Conclusion(s): Stress-induced cardiomyopathy rarely occurs in gravid females with chest pain;however, it should be considered after ruling out acute myocardial infarction. Distinguishing Takotsubo cardiomyopathy from peripartum cardiomyopathy is important as peripartum cardiomyopathy is considered a contraindication for future pregnancies. Clinical suspicion for Takotsubo cardiomyopathy should be increased in patients with a history of superimposed preeclampsia. Whether COVID-19 infection-associated inflammatory state predisposes high risk pregnant patients to Takotsubo cardiomyopathy is unknown, but this is a possible inciting factor that should be assessed in patient work up. Management should involve an interdisciplinary team approach to ensure the safety of mother and child.Copyright © 2022
ABSTRACT
Objectives: The study aims to determine the association between electrocardiographic abnormalities and in-hospital mortality of patients with Coronavirus Disease 2019 (COVID-19) infection admitted in a tertiary hospital in the Philippines. Material(s) and Method(s): We conducted a retrospective study of confirmed COVID-19-infected patients. Demographic, clinical characteristics, and clinical outcomes were extracted from the medical records. Electrocardiographic analysis was derived from the 12-lead electrocardiogram (ECG) recorded upon admission. The frequencies and distributions of various clinical characteristics were described, and the ECG abnormalities associated with in-hospital mortality were investigated. Result(s): A total of 163 patients were included in the study, most were female (52.7%) with a median age of 55 years old. Sinus rhythm (40%), nonspecific ST and T wave changes (35%), and sinus tachycardia (22%) were the frequently reported ECG findings. The presence of any ECG abnormality was detected in 78.5% of patients and it was significantly associated with in-hospital mortality (p = 0.038). The analysis revealed a statistically significant association between in-hospital mortality and having atrial fibrillation or flutter (p = 0.002), supraventricular tachycardia (SVT) (p = 0.011), ventricular tachycardia (p = 0.011), third-degree atrioventricular block (AVB) (p = 0.011), T wave inversion (p = 0.005) and right ventricular hypertrophy (RVH) (p = 0.011). Conclusion(s): The presence of any ECG abnormality in patients with COVID-19 infection was associated with in-hospital mortality. ECG abnormalities that were associated with mortality were atrial fibrillation or flutter, SVT, ventricular tachycardia, third-degree AVB, T wave inversion, and RVH.

ABSTRACT
Background: COVID-19 has been reported to cause cardiac injury. It can be detected by an electrocardiogram (ECG), which may show markers that may predict clinical outcome. Robust data on the ECG abnormalities among COVID-19 patients affected by the alpha, beta, and gamma variants have been reported, but there is paucity of data among patients affected by the delta and omicron variants. Purpose(s): This study aims to describe the cardiovascular profile, ECG findings, and clinical course of adult patients with COVID-19, and to determine the association between certain ECG findings and clinical outcomes among these patients. Method(s): We evaluated 547 COVID-19 patients admitted from June 2021 to June 2022. Clinical profiles were extracted from electronic records. Admission ECGs were independently read and adjudicated by three cardiologists. Logistic regression analysis was done to determine the association between ECG abnormalities and adverse outcomes, including in-hospital mortality, ICU admission, need for mechanical ventilation, acute respiratory distress syndrome (ARDS), shock, acute kidney injury (AKI), myocardial infarction (MI), myocarditis, venous thromboembolism (VTE), and stroke. Result(s): A Total of 547 COVID-19 patients (mean age 54;men 51.2%) were included. The most common comorbidities were hypertension, diabetes, and dyslipidemia. Majority of patients had severe COVID-19 infection (36%). On admission, 6.4% needed intubation and 14.6% died. The most common ECG abnormalities were non-specific ST-T wave changes (41.1%) and sinus tachycardia (25.6%). Other findings were ST segment depression (3.3%), T wave inversion (1.6%), and ST segment elevation (1.3%). On logistic regression analysis, intraventricular conduction delay (IVCD), T wave inversion, and poor R wave progression were significantly associated with mortality;sinus tachycardia, atrioventricular (AV) block, ST segment elevation, and T wave inversion were significantly associated with the development of VTE;left axis deviation, ST segment elevation, and T wave inversion were significantly associated with the development of ARDS;sinus tachycardia, ST segment depression, and T wave inversion were significantly associated with the development of shock;and sinus tachycardia, ST segment elevation, and early repolarization changes were significantly associated with ICU admission. No associations were established for AKI, MI, myocarditis, and need for mechanical ventilation due to the low prevalence of these outcomes. Conclusion(s): A baseline ECG in patients with COVID-19 may help predict patients who may warrant hospitalization or even intensive care monitoring. In our cohort, certain ECG abnormalities, especially sinus tachycardia, left axis deviation, ST segment elevation, ST segment depression, T wave inversion, AV block, IVCD, poor R wave progression, and early repolarization changes, were associated with adverse clinical outcomes, including in-hospital mortality.
ABSTRACT
Ventricular tachycardia (VT) is a type of broad complex tachycardia originating from a focus in the ventricle. It is one of the four important rhythms which can lead to cardiac arrest. Accurate and timely diagnosis of true VT is the cornerstone for proper management in the emergency department (ED). We present an interesting case of an electrocardiographic artifact mimicking VT, which led to a diagnostic dilemma in the ED.Copyright © 2023 Rehman, Albaroudi, Akram, Ahmad, licensee HBKU Press.
ABSTRACT
Introduction: While T-wave inversions (TWI) are associated with various pathologies, they are rarely associated with cardiac memory, termed the Chatterjee phenomenon. Case: A 76-year-old man with sick sinus syndrome with a pacemaker presented with chest tightness and new onset TWI in his precordial leads. On admission, he tested positive for COVID-19, but remained stable and only required minimal supplemental oxygen. His troponin was only slightly elevated, and EKG showed TWI throughout his precordial leads. A previous EKG had shown normal sinus rhythm without a paced rhythm or ST wave abnormalities. Interrogation of his pacemaker revealed an AV-paced rhythm. Given his chest tightness without dynamic changes in his troponin or EKG, the symptoms were considered more likely related to his COVID-19 infection, and he was discharged home. Discussion: Aberrancies in normal cardiac conduction can result in altered electrical activation, especially for those with AV pacemakers, leading some patients to develop cardiac memory, manifesting as TWI. Conclusion: AV-paced rhythm and narrow QRS complexes with TWI localized to precordial leads without evidence of active cardiac ischaemia may suggest cardiac memory, termed the Chatterjee phenomenon, requiring no invasive interventions. LEARNING POINTS: In patients with T-wave inversions, various conditions should considered in the differential diagnosis, including left bundle branch block and sick sinus syndrome, although T-wave inversions in V1-V3 are non-specific and benign.Cardiac memory, termed the Chatterjee Phenomenon, is one of the causes of T-wave inversions which is sometimes ignored.No invasive interventions are needed for T-wave inversions with the Chatterjee phenomenon.
ABSTRACT
Background and Aim: Accumulation of cases is needed to determine whether vaccines should be recommended for children because of their potential to cause myocarditis in healthy children. Method(s): We report a case in which changes in laboratory data, electrocardiogram (ECG), and magnetic resonance imaging (MRI) were tracked at our hospital. Result(s): A 12-year-old girl developed fever a day after receiving the second dose of the COVID-19 vaccine. Three days after vaccina-tion, she also developed chest pain and went to a hospital. ECG showed ST-T segment elevation. However, the symptoms were mild, and she was treated with antipyretics and analgesics. The next day, she visited the hospital again because she had mild chest pain. ECG showed a negative T-wave, and she was referred to our hos-pital. Her real-time reverse-transcription polymerase chain reac-tion tests for COVID-19 yielded negative results. Computed tomography revealed no anatomical abnormalities of the coronary arteries. The serum concentration of troponin T was elevated by 131 ng/L. Echocardiography showed the left ventricular ejection fraction to be 64%. MRI showed a normal T2 value on T2-weighted imaging;however, extracellular volume increased by 33%. Although the Lake Louise criteria was not met, we diagnosed the condition as myocarditis. She was hospitalized for 2 days and discharged without the need for steroids or gamma globulin treat-ment to relieve her symptoms. Although these findings improved 17 days after vaccination, late gadolinium enhancement was noticed on MRI. Conclusion(s): The COVID-19 vaccine-related myocarditis (C-VAM) in this case was mild and like as cases in Europe and the United States. The risk of COVID-19 associated myocarditis is more than three times the risk of C-VAM. In addition, the mor-tality rate for COVID-19 associated myocarditis is higher than that for C-VAM. The need for a vaccine to protect populations from COVID-19 should be properly recognized. However, because the symptoms of C-VAM are mild, there may be many potential patients with C-VAM. Therefore, it may be advisable to avoid strenuous exercise for approximately 1 week after vaccination. Further research is needed to determine the long-term outcomes of C-VAM because of the late enhancement identified on MRI.
ABSTRACT
Background and Aim: Cardiovascular manifestations are common (35-100%) in multisystem inflammatory syndrome in children (MIS-C), including ventricular dysfunction, shock, coronary artery dilation, pericardial effusion and conduction abnormalities. Our study aimed to analyse cardiovascular involvement in our patients with MIS-C treated in our hospital. Method(s): The retrospective cohort study included all patients with MIS-C treated from April 2020 to December 2021 in the Mother and Child Health Institute of Serbia. In every case, cardiovascular manifestations were analysed: ventricular dysfunction, coronary artery dilatation, pericardial effusion, shock and ECG changes. Result(s): The study included 77 patients, 45 boys and 32 girls, aver-age years of age 9.3 +/- 4.8. Elevated cardiac troponin I and pro-BNP were observed in 35.9% and 87.8% of patients, respectively. Myocardial dysfunction was observed in half of our patients (50.6%), with an average ejection fraction of 50.5 +/- 8.9%. Children older than 10 years had 4 times higher chances for myo-cardial dysfunction (OR 4.3, 95%CI 1.6-10.8;p = 0.003). Shock syndrome had 21.1% of children on admission, while 5.3% devel-oped shock during the in-hospital stay. Transient coronary artery (CA) dilatation was observed in 6.5% of patients;left CA in 3 pts (Z score +2,95 +/- 0.3), right CA in one patient (Z score +2), and in one LCA and RCA (RCA Z score 2.6). Transient CA dilatations were observed only in patients with KD-like clinical presentation (5/54 pts). Mild pericardial effusion with spontaneous resolution was detected in 28.6% of children, while one female adolescent had severe pericardial effusion with threatening cardiac tamponade. On the standard ECG, 53% of children had negative T wave in inferior or/and precordial leads averagely on day 2 (IQR 1-3 day);transient QTc prolongation was registered in 46% of patients, averagely on day 7 (IQR 5-9). Sinus bradycardia and coronary rhythm were registered in 42.1% of patients, while premature ven-tricular beats were observed in 2.7% of pts. left ventricle thrombus was detected in one patient with normal echocardiography find-ing. In this patient, increased activity of Factor VIII and XII was proven. Conclusion(s): Cardiac manifestations are common and potentially life-threatening in MIS-C and should be assessed for at presenta-tion and during the clinical course as indicated.
ABSTRACT
SESSION TITLE: Cardiovascular Complications in Patients with COVID-19 SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 1:45 pm INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is a rare cardiac phenomenon associated with autoimmune and inflammatory conditions seen often in young women with few conventional atherosclerotic risk factors. The presentation is indistinguishable from acute coronary syndrome and can lead to acute myocardial infarction, arrhythmias, and sudden death. We share a thought-provoking case of SCAD in a COVID-19 positive patient. CASE PRESENTATION: 51-year-old physically fit female with BMI of 22.46kg/m2, non-diabetic with recent unremarkable lipid panel and history of anxiety, postpartum cardiomyopathy 15 years prior with recovered ejection fraction presented with complaints of midsternal chest pain at rest, 9/10 intensity, radiating to the right shoulder associated with dyspnea, lasting for 3 hours until relieved by nitroglycerine patch. Initial workup revealed troponin of 3.08 and EKG consistent with acute ischemic changes without STEMI. She was incidentally found positive for SARS-CoV-2. Echocardiogram showed dyskinetic apex with normal ejection fraction. The following day, while she was on aspirin and heparin drip, she developed chest discomfort with EKG revealing dynamic T wave inversions and troponin trending up to 14.79. The patient was taken for an emergent cardiac catheterization which revealed patent coronaries with concern for distal left anterior descending artery dissection. Subsequently, the patient was continued on a heparin drip with an improvement of her symptoms. Troponin declined to 7.97 with no other COVID-19 related concerns. She was deemed medically stable and discharged home after completing her isolation. Furthermore, she underwent a cardiac and coronary artery CT angiogram 2 weeks later, showing patent coronaries and a calcium score of 0 and no findings of coronary artery disease. DISCUSSION: SCAD is an emergent condition closely associated with inflammatory conditions, systemic arteriopathy, emotional stress triggers, fibromuscular dysplasia, and pregnancy. It is not iatrogenic, traumatic or associated with atherosclerosis. The mainstay of detection of SCAD is coronary angiography. In our patient, since it was a distal LAD disease, the echo findings of dyskinetic apex helped established the diagnosis of SCAD. Management is mainly supportive usually carrying a good prognosis. In our case report, the connecting factor to SCAD was the presence of SARS-CoV-2. Our patient was without traditional risk factors for coronary artery disease, which reinforced the likelihood of SCAD instead of acute coronary syndrome. CONCLUSIONS: Thus, as the manifestations, complications, and sequelae of COVID-19 continue to emerge, we believe SCAD needs to remain a top differential in COVID -19 positive patients presenting with symptoms of the acute coronary syndrome. To better elucidate the pathophysiology of SCAD in SARS-CoV-2 patients, we encourage further vigilance of this phenomenon. Reference #1: Hayes, S. N. et al (2018, February 22).

ABSTRACT
Introduction: Cardiac disease is the leading cause of maternal death in the UK [1].We present the case of awoman with late intrauterine fetal death (IUFD) and intrapartum cardiac ischaemia. A family history of limb girdle muscular dystrophy (LGMD) may be relevant. Case Report: A 23-year-old nulliparous woman at 39 weeks of gestation presented with reduced fetal movements and IUFD was confirmed. She had no medical history, and despite two first degree relatives with LGMD, she was asymptomatic and had not been tested. Uterine contractions started and epidural analgesia was initiated. Shortly thereafter, the woman was found to be bradycardic at 35– 40 beats/min. All other observations were normal and she was asymptomatic with no detectable sensory or motor block. A 12 -lead ECG showed inferior T-wave inversion and serial troponins were markedly elevated. Caesarean section (CS) under general anaesthesia was performed at maternal request and was uneventful. Postpartum echocardiogram demonstrated a dilated left atrium, left ventricular akinesis and an ejection fraction of 45–50%. The next day the woman developed chest pain and desaturated. CTPA and CT coronary angiogram were normal. Oxygenation improved and other than sporadic chest heaviness she remained well and was discharged 4 days post CS. Cardiology follow-up did not occur due to a communication breakdown. Post-mortem of the fetus found no cause for the IUFD and no features of LGMD. Thewoman suffered a miscarriage four months after this but delivered a healthy baby at elective CS two years later. During the latter pregnancy cardiology input from a tertiary centrewas requested but did not occur due to the COVID-19 pandemic. An echocardiogram in the third trimester was normal and the woman has been well since. Discussion: Troponin rise is abnormal in pregnancy and requires investigation. IUFD in itself can lead to sequelae requiring a low threshold for investigation. The family history in this case is autosomal dominant type 1B LGMD, associated with cardiomyopathy and arrhythmias [2]. The woman has declined testing and the cause for the peripartum cardiac disease remains unknown. The recovery and recent uneventful pregnancy suggest Takotsubo’s cardiomyopathy or coronary vasospasm as additional possible diagnoses. This case also underlines the importance in sensitive communication in cases of IUFD to ensure women are investigated and not lost to follow-up.
ABSTRACT
CASE: We report a 50-year-old Caucasian female with a history of systemic lupus erythematosus (SLE) in remission and chronic kidney disease (CKD) stage 5. The patient presented with dyspnea on exertion and orthopnea for two weeks. Six weeks ago, she was diagnosed with COVID-19 after presenting to the ED for substernal chest pain, myalgias, and fatigue. During this admission, she denied any current joint pain, chest pain, or rashes. She denies a history of alcohol or illicit drug use. EKG in the ED showed T-wave inversions in lead I and aVL, stable from prior EKG. The brain natriuretic peptide level was elevated at 3,500 pg/ml. There was no transaminitis, and kidney function was at baseline. Chest x-ray showed pulmonary vascular congestion and cardiomegaly. A transthoracic echocardiogram showed a left ventricular ejection fraction of 15-20% with severe global hypokinesis. The patient had a full cardiomyopathy workup. We ruled out ischemic cardiomyopathy with a negative coronary angiogram. Non-ischemic cardiomyopathy (NICMO) workup was initiated, with a focus on viral or autoimmune myocarditis. While a cardiac MRI would have been the gold standard to assess for myocardial scarring, the patient's CKD status prohibited this possibility. Similarly, an endomyocardial biopsy was not performed due to its low sensitivity for diagnosing viral or autoimmune myocarditis. Without evidence of infiltrative disease, or other exposures, it was deemed that the patient's recent history of COVID-19 infection, in conjunction with underlying SLE, were the causes of her new-onset NICMO. The patient's dyspnea responded to intravenous bumetanide. We initiated guideline-directed medical therapy with carvedilol and isosorbide-dinitrate. She continues regular follow-up in the outpatient heart failure clinic. IMPACT/DISCUSSION: Classification and evaluation of NICMO can be broad, and thus the clinical picture plays an essential role in the workup. Acquired cardiomyopathy from prior myocarditis was the most likely etiology of our patient's new-onset NICMO. Our patient had no clinical symptoms of myocarditis prior to her exposure to COVID-19, making it unlikely that SLE was the sole driving factor. There is a known association between COVID-19 and myocarditis. A few proposed mechanisms for COVID-19 induced myocarditis include upregulation of cytokines, particularly interleukin-6, and downregulation of ACE2, leading to microvascular and cardiac pericyte dysfunction. Cytokine release from COVID-19 coupled with subclinical SLE could have acted synergistically to cause this patient's condition. Given the increasing incidence of COVID-19 infections, internists must consider COVID-19 exposures during the workup of new-onset heart failure. CONCLUSION: The workup for NICMO in the COVID-19 era must include detailed history taking for sick contacts and prior history of COVID-19 diagnosis. More research is needed to determine if COVID-19 infection can increase the risk of NICMO in patients with a known history of SLE.
ABSTRACT
CASE: A 60-year-old woman with past medical history including hypertension, nephrolithiasis, and Covid-19 4 months prior presented to the emergency department with 3 days of substernal chest pain radiating toward the back and shoulders 6 days after receiving her second dose of the BNT162b2 mRNA Covid-19 vaccine (Pfizer/BioNTech) in her left deltoid. The patient tested negative for Covid-19 and denied shortness of breath, cough, fever, or dyspnea on exertion. Her ECG was notable for more pronounced t-wave inversions in III and aVF, but further cardiac workup was unremarkable, and she was discharged the next day. The patient re-presented to care 6 days later with left arm pain, erythema, edema, and warmth. Her left bicep circumference was 31cm versus 28cm on the right. Upper extremity duplex ultrasound (US) was remarkable for deep venous thrombosis (DVT) of the left internal jugular, subclavian, axillary, and basilic veins. MRI angiogram was confirmatory. Other than her occupation as a hairdresser, the patient did not have known risk factors for DVT: no personal or family history of thromboembolism, no tobacco use, took no prescription medications, and had received all ageappropriate cancer screening. Her thrombophilia workup was negative. The patient was discharged on apixaban. Eleven days later, a venogram showed persistent clot burden in the left axillary, mid-subclavian, and brachiocephalic veins. Thrombectomy, overnight tPA infusion, and left subclavian vein stenting were performed and the patient was discharged on daily apixaban and aspirin. IMPACT/DISCUSSION: As of December 10th, 2021, the vaccine adverse event reporting system yielded 464 reports of “thrombosis” after the Pfizer/ BioNTech vaccine in individuals with no reported current illness, 32 of which occurred in the upper extremity. To our knowledge, our patient represents the first report of upper extremity deep venous thrombosis (UEDVT) shortly after receipt of the Pfizer vaccine in an otherwise healthy person. UEDVT is relatively rare: it occurs in about 0.4 to 1 per 10,000 people per year and less than 20% of incidents are idiopathic. Given the scarcity of potential causes, our case may simply reflect expected background incidence. Nevertheless, the literature includes multiple case reports of DVT after mRNA Covid-19 vaccination, including cases of lower extremity DVT and DVT with pulmonary embolism (PE) after the Pfizer vaccine, and cases of lower extremity DVT, PE, and UEDVT after the mRNA-1273 (Moderna) vaccine. Given the similar mechanism of action between the Moderna and Pfizer vaccines, it is possible that the same pathophysiology underlies the reports of DVT in these vaccine recipients. CONCLUSION: Upper extremity deep venous thrombosis after Covid-19 mRNA vaccination should remain on the differential as clinicians assess chest and arm pain following vaccination. There is a possible association between the BNT162b2 mRNA Covid-19 vaccine and upper extremity deep venous thrombosis that requires further research.
ABSTRACT
Cardiovascular complications are a frequent occurrence in Sars-CoV-2 infection. Takotsubo cardiomyopathy is a possible cause of transient ST segment elevation (1- 3% of total cases) and is characterized by a reversible left ventricular dysfunction with coronary arteries free from critical stenosis. The predominant echocardiographic pattern is an akinesia of the mid-apical myocardial segments with preserved kinetics of the basal segments. The incidence of Takotsubo cardiomyopathy showed a marked increase during the COVID-19 pandemic. Three factors mainly contribute to the onset of cardiomyopathy in patients with COVID-19: cytokine storm, adrenergic hyperactivation and microvascular dysfunction. A 79-year-old woman was hospitalized in the Pneumology department of our hospital for bilateral interstitial pneumonia Sars-CoV-2 related. In remote medical history: in 2010 diagnosis of breast cancer with negative follow-up for disease recovery, arterial hypertension, hypercholesterolemia and syndrome of reduced mobility as a result of a previous ischemic stroke. Non-invasive mechanical ventilation with c-PAP was started and, for the detection of anterolateral electrocardiographic anomalies (diffuse symmetrical negative T waves) and an increase in myocardionecrosis markers, echocardiographic evaluation was performed, which revealed an akinesia of the mid-apical segments of the left ventricle with preserved kinetics of the basal segments and severely depressed global systolic function (ejection fraction: 30%). BNP (18.100 pg /mL), interleukin-6 (339 pg /mL) and CRP (136mg /L) were elevated on blood chemistry tests. In the suspicion of Takotsubo cardiomyopathy (InterTAK Score: 67, probability: 79.8%), cardioprotective therapy with ACE inhibitor, beta-blocker, diuretics, low molecular weight heparin, double antiaggregation and statin was started, deferring coronary angiography to improved clinical conditions. In the following days, due to the respiratory and haemodynamic worsening, the patient was transferred to an intensive setting, where she was intubated and treated with levosimendan and noradrenaline. Serial echocardiograms showed a progressive improvement of the global systolic function (ejection fraction at the last checkup: 55%), with complete regression of the kinetic anomalies, confirming of the diagnostic hypothesis of stress cardiomyopathy. For a pulmonary mycotic superinfection, complicated by iatrogenic pneumothorax, in the following days the patient died. (Figure Presented).
ABSTRACT
Cardiological causes account for the majority of acute electrocardiographic (ECG) changes. The reason for this fear is the irreversibility of myocardial necrosis. Generally, various changes can be observed in the ECG, including ST-T changes, QTc prolongation, arrhythmias, and T-wave inversions. Even though T-wave inversions can be seen in myocardial ischemia/infarction, they are rarely seen in acute cerebrovascular accidents (CVAs). We present the case of a 66-year-old woman who initially presented at our facility with dizziness in the context of orthostatic hypotension. An initial cardiac evaluation revealed no cardiac involvement. She was treated with intravenous fluids (IVF), which improved her symptoms. The patient's mental status was markedly altered approximately four days after admission. In this instance, she was found to have abnormal ECG findings (not previously observed on the ECG that was obtained on the day of admission), elevated troponin T levels, as well as elevated pro-B-type natriuretic peptide (pro-BNP). The patient was given aspirin and clopidogrel immediately and was placed on a heparin drip for a suspected non-ST elevation myocardial infarction (NSTEMI). A non-contrast computed tomography of the head revealed an acute cerebrovascular accident (CVA), following which the heparin drip was stopped. The patient was then transferred to another acute care facility capable of performing neurosurgical interventions. Additionally, a computed tomography angiography (CTA) of the chest and lower extremities venous duplex showed bilateral pulmonary emboli and deep venous thrombosis (DVT), respectively.
ABSTRACT
Background: Myocarditis, an inflammation of the myocardium in the absence of ischemic injury, may be caused by viruses, drugs, and vaccines. The Myocarditis following COVID-19 vaccinations is most commonly seen in young adult males and commonly after the second dose of the mRNA vaccine. It usually presents with chest pain, dyspnoea, palpitations but has a diverse clinical presentation and varied therapeutic response. We aim to systematically collate the symptomatology, prognosis, and clinical findings of COVID-19 vaccine adverse events causing Myocarditis. Method: Following the PRISMA statement 2020, a systematic search was conducted to isolate confirmed cases of COVID-19 vaccine-induced Myocarditis. By applying the BOOLEAN logic, the following keywords were used: COVID-19, SARS-CoV-2, Myocarditis, Mortality. Four databases were searched from January 2021 through August 2021: PubMed, Science Direct, Google Scholar, and Cochrane Library;the reference lists of screened studies were searched as well (umbrella methodology). Results: In total, 12 case reports, 10 case series and 1 cohort study with a total of 107 patients were included in the final analysis. A total of 101 male patients were recorded, and 6 were female showing male dominance. The mean age of all participants was 24.73 years(SD = 13.18), ranging from 14 to 70. The most common presenting symptoms were chest pain (47.66%), fever (35.51%), and myalgia (25.23%). Lab findings showed elevated Troponin I, CRP, and ESR levels in the majority of patients. ECG was abnormal in most of the patients, which include sinus rhythm (24%), ST-elevation (42.05%) and T wave inversion (13.08%). Echo findings include decreased Ejection fraction in 19.62% of patients while 13.08% of patients having a hypokinetic left ventricular wall. Further, CMR finding suggestive of confirmed myocarditis cases in 36% patients while rest are suspected one. Overall mortality(1.86%) was low among patients. Conclusion: There is increasing evidence for Myocarditis as a rare adverse event of COVID-19 mRNA vaccination in young adults. This evidence is strongest amongst young male patients. The majority of the patients complain of chest pain and fever. In lab findings Troponin I, CRP and ESR are usually increased and ST elevation is common in the ECG. This entity is mainly treated with nonsteroidal anti-inflammatory drugs, Colchicine, Beta-blockers, ACE inhibitors, Steroids. However, prognosis and outcomes are favourable with a very low mortality rate.
ABSTRACT
Introduction: Cardiovascular complications of novel SARS-CoV-2 infection remain poorly understood with outcomes limited to index hospitalizations. Methods: This retrospective cohort study included patients with proven COVID-19 who received care at a single hospital network in Massachusetts from March 11, 2020 to May 23, 2020 and received an electrocardiogram (ECG) within 24 hours of hospital presentation. We investigated mortality and cardiovascular complications within 90 days from initial COVID-19 diagnosis. Data were electronically ed and confirmed by manual chart review. Results: A total of 1,744 patients tested positive within the hospital network during the study period. Nearly half of them (49.3%) were hospitalized and 15.5% died within 90 days. A total of 278 patients received an ECG within 24 hours, representing 23.6% of all hospitalized patients. These patients were disproportionately older (38.5 vs 58.1% over the age of 60, p < 0.01), male (49.6 vs 56.2%, p = 0.05), and white (48.1 vs 56.2, p < 0.01). Admission ECGs demonstrating ischemic changes (STelevations, ST-depressions, and T-wave inversions) or new arrhythmias (atrial fibrillation/flutter, bradyarrhythmia, supraventricular tachycardia) were identified among 10.1% and 9.0% of the patients, respectively. Heart failure and cardiomyopathy were rare findings (<1%). After adjusting for age, sex, and past medical history, ischemic changes or new-onset arrhythmias were associated with nearly five-times greater risk of death (OR: 4.9;95% CI 1.7-14.4). Conclusions: In this retrospective study among hospitalized adults with a proven COVID-19 infection, admission ECGs demonstrating ischemic changes or new-onset dysrhythmia predict a higher risk of death in the short-term.
ABSTRACT
Methods and results: A 79-year-old woman, with a history of subclinical hypothyroidism, obesity and smoke presented to the Emergency Room with dyspnoea and cold sweating. She had undergone her first dose of COVID-19 Moderna mRna vaccination just four days prior to her admission. She showed elevated HS troponin and elevated BNP at her laboratory exams. Her 12-lead ECG showed T wave inversion in the antero-lateral leads and prolongued QTc. Her transthoracic echocardiogram showed severe ejection fraction reduction due to hypokinesia of the mid-apical segments of the anterior and lateral walls of the heart. The patient was then admitted to the Cardiology ward in order to perform a coronary angiography which sowed no significant coronary stenosis. She was started on appropriate medication and discharged after a six day in-hospital stay. At discharge she showed partial recovery of her ejection fraction (EF 44%). A cardiac magnetic resonance was performed after discharge which showed no late gadolinium enhancement. Such finding allowed us to rule out the diagnosis of myocarditis. Moreover at her 3-month follow-up her ejection fraction had recovered completely. We concluded for the diagnosis of Takotsubo Syndrome secondary to vaccination. Conclusions: We presented a case of Takotsubo syndrome after vaccination with the Moderna vaccine for COVID-19. Two other similar case reports can be found in current medical literature. Female sex, post-menopausal age and the inevitable psychological stress derived by the pandemic and the vaccination may have triggered the condition.
ABSTRACT
Case report-IntroductionCOVID-19 pandemic affected medical practise significantly and caused difficulties in accessing necessary investigations at the appropriate time. As of March 2020, NHS England issued measures to redirect staffs and resources in preparation for the rising cases of coronavirus. As a result of this, non-urgent tests/treatments were put on hold. We present a new case of EGPA admitted to our district general hospital during the COVID-19 pandemic to highlight the challenges faced. The diagnosis was reached based on clinical judgment in the absence of some confirmatory tests as well as the decision of starting immunosuppressant treatment during the pandemic.Case report-Case descriptionA 41-years-old lady with a background of well-controlled asthma, presented with five days history of paraesthesia and swelling in both legs. She also reported mild pleuritic chest pain, which radiated to her left arm. Physical examination revealed left foot drop. She had reduced sensation on the L5-S1 dermatomal distribution with absent ankle reflex and reduced knee reflex of her left leg. Her left calf was swollen and tender. The rest of her examination was unremarkable.Baseline blood revealed raised WCC of 19.3 with significant eosinophilia (10). CRP and ESR were 135 mg/L and 48mm/hr, respectively. Electrocardiogram showed new T-wave inversion in the anterolateral leads with significantly raised troponin levels. There was ground glass appearance in both lungs, keeping with suspected COVID-19 and no evidence of pulmonary embolus was found on CTPA. MRI spine confirmed no evidence of cauda equina compression. Deep vein thrombosis was also excluded with US doppler.She was treated as myocarditis and pneumonia secondary to probable COVID-19 infection. Echocardiogram revealed severe LVSD (EF < 35%) with no LV hypertrophy. Three days later, she became acutely breathless and required high flow oxygen. New bilateral basal crackles were found on auscultation. Her antibiotic regimes were escalated to intravenous infusion.A revised CT report suggested the findings may correlate with eosinophilic pneumonia or EGPA. MRI of lower legs proved muscular oedema in bilaterally, which was suggestive of myositis with fasciitis. There was no significant change on the thigh musculature. CK level was slightly elevated (403 IU/L). Urinalysis was positive for blood (3+). Given the strong clinical suspicion of EPGA, a decision to start high dose steroid therapy was made, despite the pending immunology results. After the third dose of the methylprednisolone, pulsed cyclophosphamide was started along with high dose oral prednisolone. The patient was discharged home following significant clinical improvement.Case report-DiscussionThis patient has fulfilled 4 out of 6 criteria of ACR 1990 classification for EGPA, which are eosinophilia, bronchial asthma, mononeuritis multiplex and pulmonary infiltrates on radiological images. However, in the context of current pandemic, these changes on chest CT findings could also be suggestive of COVID-19 pneumonitis.At present, there is no reliable test for COVID-19. Even though RT-PCR testing has been the gold standard for diagnosing suspected cases, the clinical sensitivity and specificity of these tests are variable. A negative test may not rule out infection. In our case, the patient was tested twice at separate times to rule out the possibility of COVID-19 infection.During the pandemic, there is extremely limited access to some confirmatory tests. We were not able to perform nerve conduction studies on our patient as the service was suspended, instead, we sought neurologist's review to confirm the mononeuritis multiplex. We also sought advice from haematologist to rule out the possibility of hyper-eosinophilic syndrome as bone marrow biopsy was unavailable. The screen for atypical pneumonia, aspergillosis, viruses, and tuberculosis were negative. By excluding the alternative diagnoses related to eosinophilia, we concluded that this was likely to be a case of first presentation EGPA.Our next obstacle was intr ducing remission-induction regimens during COVID-19 pandemic. BSR does not recommend starting new treatment due to the increased risk of infection. We had to weigh out the benefits and risks of initiating immunosuppression. Our patient was made aware of the potential risks involved which include severe infection with COVID-19. She was also shifted to a side room with strict infection control precautions and PCP prophylaxis prescribed before starting pulsed methylprednisolone and cyclophosphamide. Fortunately, her neurological symptoms resolved after three days of steroid therapy. Eosinophils count dropped within 1 day to zero, after the first dose of IV methylprednisolone.Case report-Key learning pointsDespite the rising cases of COVID-19 infection, it is essential to keep an open mind and consider alternative diagnosis if a patient did not respond to conventional treatment. As EGPA and COVID-19 pneumonia share similar clinical and radiological presentation, clinical judgement is essential when making the diagnosis as the treatments for both conditions are vastly different. When EGPA is suspected, a multidisciplinary team should be involved in the evaluation of different organ involvements as well as ruling out other causes of eosinophilia. The role of specialists' inputs is extremely important in reaching the diagnosis, especially with limited access to the usual confirmatory tests due to reduced services during the pandemic.In addition, when there is an increased risk of infection such as during the COVID-19 pandemic, it is essential to weigh up the benefits and risks of commencing immunosuppressant treatment carefully. Patients need to be involved in the decision-making process as well as take precautions to minimise the risk of infection. The decision to start remission induction regimes should not be delayed if there is a presence of life or organ threatening disease manifestations in EGPA patients. Our patient has had a life-threatening disease because of multi-organ involvements (cardiac, pulmonary, and neurological systems).
ABSTRACT
PURPOSE: Cardiac involvement with COVID-19 infection has become evident by elevated troponin, cardiac arrhythmias, ST segment elevation, myocarditis, fulminant heart failure, and sudden cardiac death. We aimed to describe the association of COVID-19 and T-wave inversion (TWI) in a large case series. METHODS: We conducted an observational, retrospective study of confirmed COVID-19 cases with at least one electrocardiogram (ECG) in a large hospital in New York City (March 23, 2020-April 23, 2020). Patients with new TWI or pseudonormalization were further analyzed. Mortality and the need for invasive mechanical ventilation were the main outcomes. RESULTS: A total of 3225 patients were screened; 195 (6%) were selected for further analysis: 181 with TWI and 14 with T-wave pseudonormalization. Mean age was 66 ± 7 years; 51% were male. TWI were more commonly noted in the lateral (71%), followed by anterior (64%), inferior (57%), and septal (26%) leads. A total of 44 patients (23%) had elevated troponin. A total of 50 patients died (26%). Mortality rates of 35%, and 52% were observed in patients with diffuse TWI, and elevated troponin, respectively. Mortality rate of 80% was observed in patients with both elevated troponin and diffuse TWI. Additionally, 30% of the entire cohort and 58% of patients with elevated troponin required invasive mechanical ventilation. CONCLUSION: Our study demonstrates that new TWI is a relatively common finding in COVID-19 patients. Importantly, our findings suggest that new TWI or T-wave pseudonormalization, particularly with elevated troponin, was associated with higher rates of mechanical ventilation and in-hospital mortality.
