ABSTRACT
Aim To explore the impact of coronavirus-2019 disease (COVID-19) pandemic on emergency reper-fusion characteristics in patients with ST-segment elevation myocardial infarction (STEMI) from non-epicenter. Methods This was a retrospective study involved STEMI patients undergoing primary percutaneous coronary intervention (PPCI), who admitted to chest pain center in our hospital during the pandemic ( from January 23 to March 29 in 2020) and the same period in 2019, excluding the patients with COVID-19. Clinical characteristics and reperfusion parameters were compared between the two groups. Results A total of 64 STEMI patients undergoing PPCI were enrolled in our study, including 13 patients during the pandemic and 51 patients during the same period in 2019. No differences occurred in admission signs, GRACE scores, arrival periods, transferred patterns,the period from door to troponin,and the period from first medical contact to dual antiplatelet between the two groups ( P>0. 05). As compared with 2019, STEMI patients undergoing PPCI had an apparent reduction. Meanwhile, significant delays appeared in reperfusion parameters, in-cluding the period from symptom onset to first medical contact (10 h vs. 3. 0 h, P<0. 001), the period from first medical contact to electrocardiogram (6 min vs. 3 min, P<0. 001), the period from door to troponin (15 min vs. 12 min, P = 0. 048), the period from door to device (76 min vs. 62 min, P = 0. 017), the period from telephone to catheter activated (15 min vs. 5 min, P<0. 001) and the period from catheter arrival to device (52 min vs. 41 min, P = 0. 033). Conclusion Even in non-epicenter, the COVID-19 outbreak still delayed mechanical reperfusion significantly. © 2022, Editorial Office of Chinese Journal of Arteriosclerosis. All rights reserved.
ABSTRACT
Introduction: The Severe Acute Respiratory Syndrome Coronavirus-2 have been associated with cardiovascular adverse events including acute myocardial infarction due to a prothrombotic and hypercoagulable status, and endothelial dysfunction. Case report: We report the case of a 62-year-old women, admitted to the hospital via the emergency room for acute chest pain and dyspnea. A nasopharyngeal swab was positive for COVID19 real-time reverse transcriptase-polymerase chain reaction 11 day ago. On admission, she was hypotensive with systolic blood pressure measering 87 mmHg and tachycardic with 117 beats/min, oxygen saturation (SO2) was 94%. An 18-lead ECG revealed an infero-postero-lateral ST-elevation myocardial infarction with right ventricular involvement and a seconddegree- Mobitz Type 1 atrioventricular block. The coronary angiography from the right femoral artery showed acute thrombotic occlusion of the first diagonal branch with TIMI 0 flow and acute thrombotic occlusion of proximal right coronary artery with TIMI 0 flow. The most likely diagnosis was myocardial infarction secondary to a non-atherosclerotic coronary occlusion. The angioplasy was performed with dilatations with a semi compliant balloon, bailout implant of BMS, manual thrombus aspiration and intracoronary injection of tirofiban in the right coronary artery. The myocardial revascularization was ineffective. The patient developed significant severe hemodynamic instability and cardiac arrest for pulseless electric activity after 24 hours. Conclusion(s): The COVID-19 outbreak implies deep changes in the clinical profile and therapeutic management of STEMI patients who underwent PCI. At present, the natural history of coronary embolism is not well understood;however, the cardiac mortality rate are hight. This suggests these patients require further study to identify the natural history of the condition and to optimize management to improve outcome.
ABSTRACT
Background: Acute myocarditis corresponds to an acute inflammation of the myocardium whose origin is most often viral. Several viruses can be incriminated to note the parvovirus B19, the virus herpes of the group 6 and to a lesser degree the virus of the hepatitis C (VHC) [18,19]. Since 2019 and with the discovery of SARS COV2 some cases of myocarditis associated with covid have been noted, this last association is rare and is present in only 5% of cases [8]. The diagnosis of myocarditis is sometimes difficult and can lead to confusion with acute coronary syndrome, especially in cases of ST-segment elevation on the EKG, hence the interest of magnetic resonance imaging, which has made it possible in recent years to reduce the rate of unnecessary coronary angiography, especially in the case of young subjects with no cardiovascular risk factors. in this context we report the case of a 33 year old patient with no cardiovascular risk factors and no medical or surgical antecedents who was admitted to the emergency department for the management of acute chest pain related to acute post-covid myocarditis, the patient was initially admitted to the cardiology intensive care unit where he was put in condition and under analgesic treatment and under therapeutic protocal of covid 19 and under anticoagulation based on low molecular weight heparin at preventive dose with a good clinical evolution he was transferred thereafter to the clinical cardiology then declared outgoing under treatment of covid 19 with an appointment of control in 1 month.
ABSTRACT
The coronavirus disease 2019, also known as the COVID-19 pandemic has had a deleterious impact on daily living, with health and socioeconomic effects of a global magnitude. Acute coronary syndrome (ACS), an important cardiovascular disease with significant morbidity and mortality rates, has been frequently reported in patients with this novel virus. This review aims to discuss the potential associations between COVID-19 and ACS with the use of multiple databases, including but not limited to; PubMed, ScienceDirect, World Health Organization, and American Heart Association. We have explored the pathophysiology of ACS, focusing on COVID-19 in particular with the use of various works of literature that highlights the pattern of viral entry and replication via the angiotensin-converting enzyme II. The review has also discussed the impact of the pandemic on hospital admissions, diagnosis, and management of ACS patients, as well as briefly highlighted a possible link between the widely available COVID-19 vaccines and possible cardiovascular complications. The association between COVID-19 and ACS needs more in-depth studies to help establish whether there exists a direct causal and or inciting correlation between them. Understanding this association might lead to new research and treatment options for ACS patients.
ABSTRACT
Introduction: Data on the incidence of type 2 NSTEMI (T2MI) in hospitalized patients with COVID-19 infection has been limited to single-center studies. We propose to define the incidence of T2MI in a national cohort and identify pre-hospital patient characteristics associated with a diagnosis of T2MI in hospitalized patients with COVID-19. We will also examine the impact of T2MI on morbidity and mortality. Method(s): We performed a retrospective analysis on data from the American Heart Association COVID-19 Cardiovascular Disease Quality Improvement Registry. This national registry contains data on tens of thousands of patients hospitalized with COVID-19 from at least 122 centers across the United States. From January 2020 through May 2021, there were 709 (2.2%) out of 32,015 patients with a coded diagnosis of T2MI. We performed Wilcoxon tests, chi-squared test, and multivariable logistic regression to (1) identify predictive pre-hospital patient characteristics (Table 1) of T2MI for patients hospitalized with COVID-19 and (2) investigate the impact of T2MI on mortality and morbidity. Result(s): Patients in the T2MI group were older (71 vs. 63 years, p<0.001), and in forward selection analyses, patients with a diagnosis of T2MI had higher odds of known HTN (OR 1.79 [1.01-3.1], p=0.026) and heart failure (OR 3.46 [2.24-5.34], p<0.001). Increased age, admission troponin, CRP, and d-dimer were also associated with higher odds of T2MI. Hispanic race (OR 0.517 [0.289-0.924], p=0.026) and use of antihyperglycemics (OR 0.562 [0.377-0.836], p=0.005) were both associated with lower odds of T2MI. T2MI led to increased mortality (HR 1.32, [1.17-1.5], P<0.001) and morbidity including cardiac arrest, major bleeding, and stroke. Conclusion(s): A history of heart failure was the strongest predictor of T2MI in hospitalized COVID19 patients. Patients with a T2MI compared to those without, had significantly higher mortality and morbidity. Limitations include the heterogenous ascertainment of the T2MI diagnosis across sites in this registry.
ABSTRACT
Case Report: It is well documented that Coronavirus Disease 19 (COVID-19) patients who suffer cardiac injury have a higher mortality rate, however the exact mechanism of cardiac injury and potential complications are still unknown. Takotsubo Cardiomyopathy (TCM), which was first described in 1990 in Japan, is characterized by a transient systolic and diastolic left ventricular dysfunction with a range of wall motion abnormalities predominantly affecting women often following an emotional or physical trigger. Though TCM is seen less commonly as a cardiac complication of COVID-19, with increasing rates of cardiovascular events due to COVID-19, TCM should be taken into consideration as a potential diagnosis for a COVID-19 positive patient. Case Description: The case of a 75-year old female with a history significant for hypertension, type 2 diabetes mellitus, hyperlipidemia, and gastroesophageal reflux disease presented to the Emergency Department after a ground level fall and subsequent left hip pain. Upon primary survey, EKG showed persistent sinus tachycardia in the 130-150s, with intermittent borderline dynamic changes and a troponin that was mildly elevated at 0.10, and an initial false negative COVID-19 test. Preoperative echocardiogram showed normal left ventricle size, no regional wall abnormalities, and a left ventricular ejection fraction (LVEF) of 60-65%. In post-operative care, EKG illustrated dynamic changes in the form of ST elevation in the lateral precordial leads, as well as an increase in the cardiac troponins, from 0.07 to 3.51. A subsequent echocardiogram illustrated a drop in her ejection fraction from 60-65% to 30-35%, with evidence of left ventricular systolic dysfunction that was not noted on previous echocardiograms. Following the Mayo clinic diagnostic criteria, this patient met the diagnostic criteria for TCM, as evident by new electrocardiograph findings, non-obstructive cardiac catherization findings, echocardiogram findings illustrating transient left ventricular systolic dysfunction, modest elevations in cardiac troponins as well as the patient being a post-menopausal female. Subsequent echocardiogram on 2 week follow up showed a rebound in her ejection fraction to 50-55%. Discussion(s): Possible outcomes of TCM include cardiogenic shock, respiratory failure, and death. It is imperative that clinicians consider TCM as a possible diagnosis when treating COVID-19 patients that may be exhibiting cardiac complications. Frequent ECG monitoring and a vigilant differential should include TCM in patients presenting with COVID-19.

ABSTRACT
Aim. To study clinical and anamnestic data, as well as inhospital outcomes in patients with ST elevation myocardial infarction (STEMI) with prior coronavirus disease 2019 (COVID-19) compared with previously uninfected STEMI patients. Material and methods. This prospective study included 181 patients treated for STEMI. The patients were divided into 2 groups, depending on the anti-SARS-CoV-2 IgG titer as follows: the main group included 62 seropositive patients, while the control group - 119 seronegative patients without prior COVID-19. Anamnesis, clinical and paraclinical examination, including electrocardiography, echocardiography, coronary angiography, were performed. Mortality and incidence of STEMI complications at the hospital stage were analyzed. Results. The mean age of the patients was 62,6+/-12,3 years. The vast majority were men (69,1% (n=125)). The median time from the onset of COVID-19 manifestations to STEMI was 60,00 [45,00;83,00] days. According to, the patients of both groups were comparable the severity of circulatory failure (p>0,05). Coronary angiography found that in patients of the main group, Thrombolysis In Myocardial Infarction (TIMI) score of 0-1 in the infarct-related artery was recorded much less frequently (62,9% (n=39) vs, 77,3% (n=92), p=0,0397). Patients of the main group demonstrated a lower concentration of leukocytes (9,30*109/l [7,80;11,40] vs 10,70*109/l [8,40;14,00], p=0,0065), higher levels of C-reactive protein (21,5 mg/L [9,1;55,8] vs 10,2 mg/L [5,1;20,5], p=0,0002) and troponin I (9,6 ng/mL [2,2;26,0] vs 7,6 ng/mL [2,2;11,5], p=0,0486). Lethal outcome was recorded in 6,5% (n=4) of cases in the main group and 8,4% (n=10) in the control group (p=0,6409). Both groups were comparable in terms of the incidence of complications (recurrent myocardial infarction, ventricular fibrillation, complete atrioventricular block, stroke, gastrointestinal bleeding) during hospitalization (p>0,05). Conclusion. Patients with STEMI after COVID-19, despite a more burdened history and higher levels of C-reactive protein and troponin I, compared with STEMI patients without COVID-19, did not differ significantly in clinical status, morbidity, and inhospital mortality.Copyright © 2023, Silicea-Poligraf.

ABSTRACT
Background: Identification of athletes with cardiac inflammation following COVID-19 can prevent exercise fatalities. The efficacy of pre and post COVID-19 infection electrocardiograms (ECGs) for detecting athletes with myopericarditis has never been reported. We aimed to assess the prevalence and diagnostic significance of novel 12-lead ECG patterns following COVID-19 infection in elite soccer players. Method(s): We conducted a multicentre study over a 2-year period involving 5 centres and 34 clubs and compared pre COVID and post COVID ECG changes in 455 consecutive athletes. ECGs were reported in accordance with the International recommendations for ECG interpretation in athletes. The following patterns were considered abnormal if they were not detected on the pre COVID-19 infection ECG: (a) biphasic T-waves;(b) reduction in T-wave amplitude by 50% in contiguous leads;(c) ST-segment depression;(d) J-point and ST-segment elevation >0.2 mV in the precordial leads and >0.1 mV in the limb leads;(e) tall T-waves >=1.0 mV (f) low QRS-amplitude in >3 limb leads and (g) complete right bundle branch block. Athletes exhibiting novel ECG changes underwent cardiovascular magnetic resonance (CMR) scans. One club mandated CMR scans for all 28 (6%) athletes, despite the absence of cardiac symptoms or ECG changes. Result(s): Athletes were aged 22+/-5 years (89% male and 57% white). 65 (14%) athletes reported cardiac symptoms. The mean duration of illness was 3+/-4 days. The post COVID ECG was performed 14+/-16 days following a positive PCR. 440 (97%) athletes had an unchanged post COVID- 19 ECG. Of these, 3 (0.6%) had cardiac symptoms and CMRs resulted in a diagnosis of pericarditis. 15 (3%) athletes demonstrated novel ECG changes following COVID-19 infection. Among athletes who demonstrated novel ECG changes, 10 (67%) reported cardiac symptoms. 13 (87%) athletes with novel ECG changes were diagnosed with inflammatory cardiac sequelae;pericarditis (n=6), healed myocarditis (n=3), definitive myocarditis (n=2), and possible/probable myocarditis (n=2). The overall prevalence of inflammatory cardiac sequelae based on novel ECG changes was 2.8%. None of the 28 (6%) athletes, who underwent a CMR, in the absence of cardiac symptoms or novel ECG changes revealed any abnormalities. Athletes revealing novel ECG changes, had a higher prevalence of cardiac symptoms (67% v 12% p<0.0001) and longer symptom duration (8+/-8 days v 2+/-4 days;p<0.0001) compared with athletes without novel ECG changes. Among athletes without cardiac symptoms, the additional yield of novel ECG changes to detect cardiac inflammation was 20% (n=3). Conclusion(s): 3% of elite soccer players demonstrated novel ECG changes post COVID-19 infection, of which almost 90% were diagnosed with cardiac inflammation during subsequent investigation. Most athletes with novel ECG changes exhibited cardiac symptoms. Novel ECGs changes contributed to a diagnosis of cardiac inflammation in 20% of athletes without cardiac symptoms.
ABSTRACT
Background: While immune checkpoint inhibitors (ICI) -induced myocarditis and coronavirus disease 2019 (COVID-19) vaccine-induced myocarditis are considered to be rare;they are both significant side effects, suggested being caused by activation of the immune system against the myocardium. We aimed to assess whether both phenomena share similar presenting characteristics. Method(s): We included patients diagnosed with either ICI or COVID-19 vaccine-induced myocarditis at our medical center. We performed a retrospective assessment of clinical presentation, blood tests, and advanced echocardiography, including speckle strain. Result(s):We included 18 patients diagnosed with ICI (ICI group) or COVID- 19 vaccine (COVID-19 group)-induced myocarditis, and 20 patients with viral myocarditis (Viral group) as a control group. The median age was significantly older in the ICI group (74 years) compared to the COVID-19 and Viral groups (20 and 24 years), p<0.001. The clinical presentation in the COVID-19 group was more similar to the Viral group, presenting mainly with chest pain and fever, while the ICI group presented mainly with dyspnea. ST-elevation was frequent in the COVID-19 and Viral groups and absent in the ICI group, p=0.004. Median peak high sensitivity troponin I values were markedly lower in the ICI group compared to the COVID-19 and Viral groups (619 ng/L vs. 15527 ng/L vs. 7388 ng/L, p=0.004). While the median left ventricular ejection fraction was 60% among all groups, patients in the ICI group presented with mean lower LV global longitudinal strain (-13%) and left atrial conduit strain (17%), compared to the COVID-19 (-17% and 30%) and Viral groups (-18% and 37%), p=0.016 and p=0.001. Conclusion(s): While the suspected mechanism is an activation of the immune system in both ICI and the COVID-19 vaccine-induced myocarditis, we found that the clinical presentation, cardiac biomarkers, and advanced echocardiography of the COVID-19 vaccine, are more similar to viral myocarditis than to ICI-induced myocarditis.
ABSTRACT
Background: It has been previously reported during the first COVID outbreak that patients presenting with ST-Segment Elevation Myocardial Infarction (STEMI) and concurrent COVID-19 infection have increased thrombus burden and poorer outcomes [1]. Subsequently, there have been multiple further waves of the pandemic with the emergence of at least two new COVID-19 variants and the emergence of vaccinations. To-date, there have been no reports comparing the outcomes of COVID-19-positive STEMI patients across all waves of the pandemic. Purpose(s): The purpose of this study was to compare the baseline demographic, procedural and angiographic characteristics alongside the clinical outcomes of patients presenting with STEMI and concurrent COVID-19 infection across the COVID-19 pandemic in the UK. Method(s): This was a single-centre, observational study of 1250 consecutive patients admitted with confirmed STEMI treated with primary percutaneous coronary intervention (PCI) at Barts Heart Centre between 01/03/2020 and 10/03/2022. COVID +ve patients were split into 3 groups based upon the time course of the pandemic (Wave 1: March 2020-June 2020, Wave 2: Sept 2020-March 2021, Wave 3: October 2021-March 2022). Comparison was made between waves and with a control group of COVID-ve patients treated during the same timeframe. Result(s): A total of 135 COVID +ive patients with STEMI (1st Wave: 39 patients, 2nd Wave: 60 patients, 3rd wave 35 pts) were included in the present analysis;and compared with 1115 COVID negative patients. Significant changes in the baseline characteristics, angiographic features and clinical outcomes of COVID +ive patients occurred over time. Early during the pandemic (Wave 1 2020), STEMI patients presenting with concurrent COVID-19 infection had high rates of cardiac arrest, evidence of increased thrombus burden (higher rates of multi-vessel thrombosis, stent thrombosis, higher modified thrombus grade higher use of GP IIb/IIIa inhibitors and thrombus aspiration, coagulability (more heparin for therapeutic ACT), bigger infarcts (lower myocardial blush grade and left ventricular function) and worse outcomes (mortality). However, by wave 3 (late 2021/2022), no differences existed in clinical characteristics, thrombus burden, infarct size or outcomes between COVID +ive patients and those without concurrent COVID-19 infection with significant differences compared to earlier COVID +ve patients. Poor outcomes later in the study period were predominantly in unvaccinated individuals. Conclusion(s): Significant changes have occurred in the clinical characteristics, angiographic features and outcomes of STEMI patients with COVID- 19 infection treated by primary PCI during the course of the pandemic. Importantly it appears that angiographic features and outcomes of recent waves are no different to a non-COVID-19 population.
ABSTRACT
Background: Delayed door-to-balloon (DTB) time and deterioration of inhospital mortality during the coronavirus disease 2019 (COVID-19) pandemic have been reported. Little is known about the impact of changes in in-hospital medical management before primary percutaneous coronary intervention (PCI) for COVID-19 such as screening test (antigen or polymerase chain reaction (PCR) tests, chest CT for excluding the pneumoniae) and primary PCI under full personal protective equipment (PPE) on DTB time and in-hospital mortality. Purpose(s): The purpose of this study was to evaluate the impact of inhospital medical management for COVID-19 on DTB time and in-hospital mortality during COVID-19 pandemic period. Method(s): We compared DTB time and in-hospital mortality of 502 STelevation myocardial infarction (STEMI) patients during COVID-19 pandemic (February 2020 and January 2021) with 2035 STEMI patients before pandemic (February 2016 and January 2020) using date from Mie ACS registry, a retrospective and multicenter registry. Result(s): The COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was performed on 173/502 (34.5%) patients (antigen or PCR tests;39 (7.8%), chest CT;156 (31.3%), full PPE;11 (2.2%)). These patients had lower rate of achievement of DTB time <=90 min compared with others (Figure 1A). Moreover, In-hospital management of COVID-19 screening tests and/or primary PCI under full PPE was an independent factor of DTB time>90 min with odds ratio of 1.94 (95% confidential interval: 1.37-2.76, p<0.001). In addition, in-hospital mortality of those patients was higher compared with others (Figure 1B). Conclusion(s): In-hospital medical management for COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was the independent factor of DTB time>90 min. This study reinforces the need to focus efforts on shortening DTB time, while controlling the epidemic of infection.
ABSTRACT
Clinical Information Patient Initials or Identifier Number: SHS Relevant Clinical History and Physical Exam: Mr. SHS was admitted in August 2022 for acute decompensated heart failure secondary to NSTEMI, complicated with ventricular tachycardia (VT). CPR was performed for6 minutes on the day of admission and was subsequently transferred to the Cardiac Care Unit. His hospital stay was complicated with Covid-19 infection(category 2b) which he recovered well from. During admission, he developed recurrent episodes of angina. Physical examination was otherwise unremarkable. His ejection fraction was 45%. Relevant Catheterization Findings: Cardiac catheterization was performed, which revealed significant calcification of left and right coronary arteries. There was a left main stem bifurcation lesion (Medina 0,1,1) with subtotal occlusion over ostial the LAD, receiving collaterals from RCA and 90% stenosis over ostial LCx. RCA was dominant, heavily calcified with no significant stenosis. He was counselled for CABG (Syntex score26) but refused. As he was symptomatic, he was planned for PCI to the left coronary system. [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: The left main was engaged with a 7F EBU 3.5guiding catheter via transradial approach. Sion Blue wired into LAD and LCx. IVUS catheter couldn't cross the LAD and LCx lesions, hence we decided for up front rotational atherectomy. Sion blue was exchanged to Rotawire with the assistance of Finecross microcatheter. A 1.5mm burr was used at 180000 rpm. After the first run of rotablation, patient developed chest pain and severe hypotension (BP ranging 50/30). 4 inotropes/vasopressors were commenced. The shock was refractory hence an intraarterial balloon pump was inserted. Symptoms and blood pressure improved. Another 2 runs of atherectomy done (patient developed hypotension after each run). IVUS examination then showed calcification of proximal to mid LAD with an IVUS Calcium score of 3. LAD was further predilated with Scoreflex balloon 3.0/20mm at 8-22ATM. LCx was predilated with Scoreflex balloon 2.0/15mm at 12-14ATM. DCB Sequent Please NEO2.0/30mm was deployed at 7ATM at ostial to proximal LCx. Proximal to mid LAD was stented with Promus ELITE 2.5/32mm at 11ATM, which was then post dilated with stent balloon at 11ATM. Ostial LM to proximal LAD (overlap) was stented with Promus ELITE 4.0/28mm at 11ATM. LMS POT was then done with NC Balloon 4.0/15mm at 24ATM. LCx was rewired and kissing balloon technique with NC balloon 4.0/15mm at 14ATM (LAD) and NC balloon 2.0/10mm at 12ATM (LCx) was done, followed by a final POT with NC balloon 4.0/15mm at 14ATM. Final IVUS showed good MSA. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): This patient developed hemodynamic instability with each rotational atherectomy run, hence we decided not to perform rotablation to the circumflex artery. His hemodynamic condition improved with the use of intra aortic balloon pump. IABP use can reduce procedural event rate and potentially reduce long term mortality in appropriately selected patients who are at high risk of adverse events. He was followed up a month following the procedure and remained asymptomatic. For complex, calcified coronary lesions involving the left main stem, coronary artery bypass graft surgery is an alternative option.Copyright © 2023
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
Widely considered safe, effective, and essential for pathogenic immunity, vaccines have proven to be one of the most important discoveries to date in medicine. Adverse reactions to vaccines are typically trivial but there have been extremely rare reports of vaccine induced myocarditis, particularly with the Tdap vaccine. This is thought to be due to a hypersensitivity reaction. In efforts to combat the SARS-CoV-2, prompt response from Pfizer-BioNTech and Moderna lead to vaccine development with a novel method, synthesized from modified messenger RNA. Despite minimal side effects on initial trials, reports of vaccine induced myocarditis have resulted. A majority of these cases occurred following subsequent doses for those previously inoculated. A descriptive study published in JAMA in January 2022 reviewed the Vaccine Adverse Event Reporting System (VAERS) in collaboration with the CDC described only 1626 cases of myocarditis, of which the majority occurred within days of the second dose. This review was limited by reviewing a passive reporting syndrome with variable quality data and without follow up data post diagnosis of myocarditis. Here we present a case of myocarditis occurring less than 24 hours after the second dose of Pfizer-BioNTech vaccine with 3 month follow up. A 23 year old man received his second dose of the COVID-19 vaccine in the morning. Within a few hours he experienced chest pain, chills, weakness, and fatigue. These dissipated by 7pm. He is a member of the National Guard and during drills the next day experienced stabbing substernal chest pain for which he sought evaluation. The pain radiated into his left jaw, worse with deep inspiration and worse in the left lateral decubitus position. He is a 1 PPD smoker with no personal or family history or cardiac disease. A friction rub was heard on physical exam. His troponin I peaked at 2.6ng/mL. His EKG showed normal sinus rhythm, a TTE showed a normal EF with no pericardial effusion. He was given aspirin 81 mg and started on a heparin drip for possible NSTEMI. The next day his pain decreased and a cardiac MRI demonstrated no inflammation. His serum coxsackie and parvovirus titers were negative. He was instructed to continue the aspirin, limit exercise for 8 weeks, and stop smoking. Upon follow up 3 months later the patient denied any recurrent chest pain and was advised to continue the aspirin. But the original bout of myocarditis limited his participation in the National Guard. Our case illustrates that exposure to an immunological trigger, the COVID-19 vaccine, leading to myocarditis was extremely short compared to typical cases of viral induced or vaccine hypersensitivity reaction. A proposed mechanism is molecular mimicry between the spike protein and myocardial contraction proteins. It also demonstrates that the vaccine can cause morbidity in patients, especially younger males. It also exemplifies that this may be a short lived phenomenon, long term follow up is still needed. With the rate of vaccination increasing, there needs to be a low threshold to consider myocarditis in young adults who have new chest pain after receiving an mRNA based vaccine.Copyright © 2022
ABSTRACT
Background: The COVID-19 pandemic led to extensive restrictions in Germany in 2020, including the postponement of elective interventions. We examined the impact on ST-elevation myocardial infarction (STEMI) as an acute and non-postponable disease. Method(s): Using German national records, all STEMI between 2017 and 2020 were identified. Using the number of STEMI cases between 2017 and 2019, we created a forecast for 2020 using poisson regression models and compared it with the observed number of STEMI in 2020. Result(s): From 2017 to 2020, 248,062 patients were treated for a STEMI in Germany. Mean age was 65.21 years and 28.36% were female. When comparing forecasted and observed STEMI in 2020, a correlation can be seen: Noticeably fewer STEMI were treated in those weeks respectively months with an increasing COVID-19 hospitalization rate (monthly percentage decrease in STEMI: March -14.85% April -13.39%, November -11.92%, December -22.95%). At the same time, the risk-adjusted in-hospital mortality increased significantly at the peaks of the first and second waves (monthly in-hospital mortality: April RR=1.11 [95% CI 1.02;1.21], November 1.13 [1.04;1.24], December 1.16 [1.06;1.27]). Conclusion(s): The COVID-19 pandemic led to a noticeable decrease in the number of STEMI interventions in Germany at the peaks of the first and second waves in 2020, corresponding to an increase in COVID-19 hospitalizations. At the same time, in-hospital mortality after STEMI increased significantly in these phases. (Figure Presented).
ABSTRACT
Background: The COVID-19 pandemic had influenced the patient's behavior and impacted the homeostasis to a pro-thrombotic niveau. Aim(s): The study aimed to follow the impact of COVID-19 on the incidence and prognosis of cardiogenic shock complicated initially acute myocardial infarction (CS-AMI). Method(s): We used data entered into a large national all-comers registry of coronary intervention over five years. From 1/2016 to 12/2020, 50,745 AMI patients were included, and 2,822 (5.6%) initially had CS. Result(s): The incidence of CS-AMI was significantly higher in the COVID period (2020) than the mean incidence in 2016-2019 (5.5% vs 6%, p=0.032). The difference was caused by significant increase of CS in acute STEMI (7.6% vs. 8.7%, p=0.011);it was 7.1% in 2016, 7.8% (2017), 7.6% (2018), 7.8% (2019), and 8.7% (2020). The CS complicated 2.3% (2016), 2.7% (2017), 2.7% (2018), 2.8% (2019), and 2.8% (2020) of NSTEMI. The observed rise in CS-STEMI incidence each month during the pandemic compared to the average incidence in non-pandemic years correlated with the substantial increase in the number of COVID infected/ hospitalized (Table 1). In these months, no changes in time delay to reperfusion layout were observed in CS-STEMI patients (Table 2). Except of less frequent history of previous PCI (13.9% and 8.2%, p<0.001), we found no significant differences in the followed CS-STEMI patient characteristics in 2016-2019 and 2020;men 72.7% and 75.4% (p=0.1), mean age (SD) 66.3 (12.3)yrs and 66.3 (12.2) yrs, Diabetes 20.9% and 19.1% (p=0.2), CKD 5.4% and 5.7% (p=0.4), previous CABG 4.5 and 4.2% (p=0.5), left main disease (14.3% and 16%, p=0.5), one vessel disease 24.9% and 32.1% (p=0.9), pre-PCI TIMI flow 0 64.4% and 66.2% (p=0.6), post-PCI TIMI flow 3 76.7% and 76.9%. The COVID pandemic didn't influence the proportions of pre-hospital resuscitated CS-AMI patients (57.5% and 58.7%, p=0.6) and those on mechanical ventilation (67.8% and 68.3%, p=0.8). The 30-day mortality trend of CS-AMI was 53.7% in 2016, 51.6% (2017), 49.7% (2018), 49.3% (2019), and 47.9% (2020). And in CS-STEMI it was 50.8%, 47.1%, 46.4%, 44.1%, and 45.3% (P2019 vs. 2020 =0.8), respectively. Conclusion(s): Data from a large national all-comer registry showed an increase in the proportion of patients admitted to hospitals with STEMI complicated by CS in the year of the COVID pandemic. The CS rise correlated with the increase in the COVID infected population. Factors other than the patient's cardiovascular risk profile or prolongation of a time delay to reperfusion influenced this trend. We suggest that the availability of health care and patient adherence may have affected the risks control. We did not observe any effect of the pandemic on CS-AMI mortality. (Figure Presented).
