ABSTRACT
Introduction: Variants in PPP1R13L are associated with severe childhood-onset cardiomyopathy resulting in rapid progression to death or cardiac transplantation. PPP1R13L is proposed to encode a protein that limits the transcriptional activity of the NFkappaB pathway leading to elevated IL-1, IL-6, and TNF-alpha production in murine models. Optimal medical management for PPP1R13L-related cardiomyopathy is unknown. Here we report usage of a targeted anti-IL-1 immuno-modulatory therapy resulting in cardiac stabilization in a pediatric patient with congenital cardiomyopathy secondary to PPP1R13L variants. Case Report: A 4-year-old boy presented acutely with fever in the setting of persistent abdominal pain, vomiting, fatigue, and decreased appetite for two months following a mild COVID-19 related illness. Echocardiogram revealed severely depressed biventricular systolic function with an ejection fraction of 30%. Due to acute decompensated heart failure symptoms with hemodynamic instability, he was intubated and placed on continuous inotropic infusions with aggressive diuresis. Cardiac MRI demonstrated extensive subepicardial to near transmural fibrosis by late gadolinium enhancement in right and left ventricles. An implantable cardioverter-defibrillator (ICD) was placed due to frequent runs of polymorphic non-sustained ventricular tachycardia. Testing for viral pathogens was positive for rhino/enterovirus. Initial genetic testing was non-diagnostic (82-gene cardiomyopathy panel) but given the patient's significant presentation whole genome sequencing was pursued that showed two separate PPP1R13L variants in trans (c.2167A>C,p.T723P and c.2179_2183del,p. G727Hfs*25, NM_006663.4). Patient serum cytokine testing revealed elevations in IL-10 (4.7 pg/mL) and IL-1beta (20.9 pg/mL). Given the patient's tenuous circumstances and concern for continued progression of his cardiac disease, a trial of IL-1 inhibition via anakinra dosed at 3 mg/kg or 45 mg daily was initiated following hospital discharge. With approximately 6 months of therapy, the patient's cardiac function is stable with normalization of IL-10 and IL-1beta serum levels. Notably, the ventricular arrhythmia decreased after initiation of anakinra with no ICD shocks given. Therapy overall has been well tolerated without infectious concerns. Conclusion(s): In patients with PPP1R13L-related cardiomyopathy, immuno-modulatory therapies should be considered in an attempt to slow cardiac disease progression.Copyright © 2023 Elsevier Inc.
ABSTRACT
2020 and COVID gave the Health Care system a whole new set of challenges. But every country had a different experience. While Australia braced itself for a similar situation to Italy, New York or London, our experience turned out to be as unique as everyone else. This presentation looks at the Monash Heart response to COVID and the actual reality of what occurred. It will look at some of the common conditions COVID produced that ECHO helped diagnose, and the Protocols and Practices we used to address the challenges we faced as a Sonographer. We can also look at what we learned and how we can take this into our present and future practice.
ABSTRACT
Objective To explore the clinical effect and safety of Suhexiang Pills () in the treatment of patients with tachycardia after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Methods A total of 138 patients with tachycardia after SARS-CoV-2 infection admitted to eight hospitals such as 971st Hospital of the PLA Navy, Changzhou Second People's Hospital, Xuzhou First People's Hospital, Henan Provincial People's Hospital, Henan Chest Hospital from February 2023 to March 2023 were randomly divided into control group and treatment group, with 87 patients in the treatment group and 51 in the control group. Patients in the control group were po administered with betaloc, once a day, and the initial dose was 23.75 mg, adjusted in time according to the patient's heart rate. Patients in the treatment group were po administered with Suhexiang Pills, 1 pill/time, twice daily. Patients in two groups were treated for 7 d. The clinical efficacy of the two groups was observed, and the heart rate and cardiac function indexes, RR interval, blood oxygen saturation and adverse reactions were compared between the two groups before and after treatment. Results After treatment, the total effective rate of the treatment group was 98.85%, and the total effective rate of the control group was 90.20%, and the difference between the two groups was statistically significant (P < 0.05). After treatment, heart rates were significantly decreased in both groups (P < 0.05), and the heart rates of the treatment group were significantly better than those of the control group (P < 0.05) on the 7th day of treatment. After treatment, the level of left ventricular ejection fraction (LVEF) in both groups was significantly higher than that before treatment (P < 0.05), and there was statistical difference between the treatment group and the control group (P < 0.05). The levels of left ventricular end diastolic dimension (LVEDD) and left ventricular end-systolic diameter (LVESD) in the treatment group significantly decreased than that before treatment (P < 0.05), and there was no statistical difference compared with the control group (P > 0.05). After treatment, the maximum RR interval in both groups reached the normal range on the third day, and the treatment group was significantly better than the control group (P < 0.05). Blood oxygen saturation of the treatment group was significantly increased on the 7th day of treatment compared with before treatment (P < 0.05), but there was no statistical significance between the two groups (P > 0.05). There was no significant difference in the total incidence of adverse events between the two groups (P > 0.05). Conclusion Suhexiang Pills decrease heart rates in patients with tachycardia after SARS-CoV-2 infection, which was equivalent to the effect of western medicine, and can protect heart, improve heart function to a certain extent.Copyright © 2023 Editorial Office of Chinese Traditional and Herbal Drugs.

ABSTRACT
Introduction: Children requiring venoarterial (VA) extracorporeal membrane oxygenation for long durations may have increased risk of complications compared to venovenous (VV) ECMO. The purpose of this study was to evaluate the feasibility and safety of conversion from VA to VV ECMO. Method(s): This is a retrospective review of all children requiring VA ECMO who underwent conversion to VV ECMO at a single institution, from 2015- 2022. Indications for and methods of conversion were examined as well as adverse events including re-operation, ischemic complications, renal failure, and mortality. Descriptive statistics were calculated. Result(s): Of 422 pediatric patients on initial VA ECMO, only three children (0.7%) underwent conversion from VA to VV support, ages 10-19: for hypoxic respiratory failure due to COVID19, for cardiac dysfunction following orthotopic heart transplant, and for sepsis with associated left ventricular dysfunction. The indications for conversion were bleeding from cannulation site (n=2, 66%) and an anticipated prolonged ECMO run (n=1, 33%). For all three patients, the method of conversion was cutdown with femoral arterial repair followed by placement of additional jugular venous cannulas (n=2, 66%) or insertion of a singular jugular bicaval venous cannula with removal of the femoral cannulas (n=1, 33%). The median time on VA ECMO prior to conversion was 8 days (range 4-54 days). All 3 patients were managed with renal replacement therapy with 1 patient (33%) progressing to long term dialysis. There were no significant ischemic limb complications although one (33%) patient developed a femoral artery pseudoaneurysm that required re-operation. Two of the three patients (66%) were able to be decannulated at a median of 23.5 days (range 8-39 days) following conversion to VV ECMO and survived to discharge. The other patient was unable to be decannulated after successful conversion and care was withdrawn. Conclusion(s): Based on this small pilot study, conversion to VV ECMO from initial femoral VA ECMO cannulation is safe and feasible. Indications for conversion include coagulopathy and need for extended ECMO run after recovery of cardiac function.
ABSTRACT
Case Presentation: Term male infant born to SARS-CoV-2 positive mother with infant testing negative. ECG for perinatal bradycardia revealed ventricular pre-excitation. Echocardiogram showed asymmetric LV hypertrophy with prominent trabeculations, subaortic narrowing with no pressure gradient, and normal biventricular systolic function. Rapid increase in RV pressure estimates and NT-proBNP in first week if life concerning for diastolic dysfunction. Anti-arrhythmic therapy initiated for SVT with subsequent resolution. Later, developed progressive LV dilation and systolic dysfunction. Myocardium showed regions resembling non-compaction and others concerning for infiltrative process. Cardiac MRI showed no obvious tumors, but rhabdomyomas could not be ruled out given similar appearance to myocardium. Due to worsening heart failure, everolimus therapy initiated to target potential rhabdomyomas while awaiting genetic testing for tuberous sclerosis. Subaortic narrowing and LV hypertrophy improved within days, and LV appearance became more consistent with non-compaction. Genetic testing revealed a TSC2 gene variant consistent with tuberous sclerosis. Systolic function improved, and patient discharged on afterload reduction. Echocardiogram 6 months post-discharge shows continued LV dilation and mild systolic dysfunction. Discussion(s): Although outflow obstruction and arrhythmias are common with cardiac rhabdomyomas and can cause dysfunction, our patient developed progressive dysfunction in the absence of outflow tract gradient or prolonged arrhythmia. As rhabdomyomas subsided, it became clearer that he had an underlying cardiomyopathy. We suspect that rhabdomyomas in the setting of abnormal myocardium led to abnormalities in myocardial contractility and compliance causing combined systolic and diastolic dysfunction. After complete resolution of rhabdomyomas, cardiac function has improved. However, he continues to have ventricular dilation and mild dysfunction attributable to cardiomyopathy. It is unlikely that mother's SARS-CoV-2 infection played a role as infant tested negative and clinical picture was not consistent with myocarditis.
ABSTRACT
Case Presentation: A 10 year old male with prior COVID-19 exposure presented with 7 days of fever, rash, cough, vomiting, and hypotension. Laboratory evaluation was notable for SARS-CoV2 antibodies, elevated cardiac enzymes, BNP, and inflammatory markers. Initial echocardiogram showed normal cardiac function and a small LAD coronary aneurysm. He was diagnosed with Multisystemic Inflammatory Syndrome in Children (MIS-C) and given methylprednisolone and IVIG. Within 24 hours, he developed severe LV dysfunction and progressive cardiorespiratory failure requiring VA-ECMO cannulation and anticoagulation with bivalirudin. Cardiac biopsy demonstrated lymphocytic infiltration consistent with myocarditis. On VA-ECMO, he had transient periods of complete AV block. With immunomodulator treatment (anakinra, infliximab) and 5 days of plasmapheresis, inflammatory symptoms and cardiac function improved. He weaned off ECMO, and anticoagulation was transitioned to enoxaparin. He had left sided weakness 5 days later, and brain MRI revealed an MCA infarct. Ten days later, he had focal right sided weakness and repeat MRI showed multiple hemorrhagic cortical lesions, thought to be thromboembolic with hemorrhagic conversion secondary to an exaggerated inflammatory response to an MSSA bacteremia in the setting of MIS-C. Enoxaparin was discontinued. After continued recovery and a slow anakinra and steroid wean, he has normal coronary arteries, cardiac function, and baseline ECG but requires ongoing neurorehabilitation. Discussion(s): COVID-19 infection in children is often mild, but MIS-C is an evolving entity that can present with a wide range of features and severity. This case highlights two concepts. While first degree AV block is often reported in MIS-C, there is potential for progression to advanced AV block. Close telemetry monitoring is critical, especially if there is evidence of myocarditis. MIS-C shares features with Kawasaki disease, with a notable difference being a higher likelihood of shock and cardiac dysfunction in MIS-C. In MIS-C patients with cardiovascular collapse requiring ECMO, there is a risk for stroke. There should be a low threshold for neuroimaging and multidisciplinary effort to guide anticoagulation in these complex cases.
ABSTRACT
Purpose of Study Treatment outcomes of children diagnosed with MIS-C are unclear and warrant investigation. The purpose of this study is to investigate the characteristics of pediatric patients diagnosed with MIS-C and their treatment outcomes with an emphasis on fatalities associated with MISC. Methods Used A literature review using Google Scholar and Pubmed using keywords such as 'Multisystem Inflammatory Syndrome in Children', 'Pediatric Inflammatory Multisystem Syndrome', and 'Coronavirus Disease 2019' was conducted. We included studies of hospitalized MIS-C patients with a sample size of more than 15. Summary of Results Of ten studies published before August 2020, five reported hospitalized MIS-C cases in the United States and five in Europe. A total of 514 hospitalized patients were reported with a sample size of 15 to 186 in various studies. Of 514 patients, 431 (84%) tested positive for SARS-CoV-2 via RT-PCR or serology. In different studies, 50% to 100% of MIS-C patients required PICU admission, 10% to 54% were intubated, and up to 80% required vasopressors. In studies that reported echocardiogram results, coronary artery dilations or aneurysm were noted in up to 93%, and depressed cardiac function was reported in 51- 100% of MIS-C patients. Treatment of MIS-C patients included intravenous immunoglobulins (IVIG) 388/514 (75%) plus steroids 288/514 (56%), along with anticoagulants and Anakinra 26/514 (5%). In total, 23 patients were put on ECMO, and of those, 16 (70%) survived. The larger studies reported fatality rate of 2% to 3% in hospitalized MIS-C patients. A total of 10 deaths were reported. Of the fatality causes that were described, 3 were associated with cerebral infarction after ECMO, 2 had not received IVIG, systemic glucocorticoids, or immunomodulators, and another 2 had co-morbidities. Conclusions Our review suggests that children with MIS-C who are hospitalized typically have a severe disease course. The outcome in vast majority of patients is favorable but death can occur, most likely as a result of cardiac dysfunction or cerebral infarction. Larger studies are needed to identify clinical features as well as laboratory and diagnostic parameters that predict disease severity and outcome.
ABSTRACT
Purpose of study Since mid-April 2020 in Europe and North America, clusters of pediatric cases with a newly described severe systemic inflammatory response with shock have appeared. Patients had persistent fevers >38.5 C, hypotension, features of myocardial dysfunction, coagulopathy, gastrointestinal symptoms, rash, and elevated inflammatory markers without other causes of infection. The World Health Organization, Centers for Disease Control, and Royal College of Paediatrics associated these symptoms with SARS-CoV-2 as multisystem inflammatory syndrome in children (MIS-C). Cardiac manifestations include coronary artery aneurysms, left ventricular systolic dysfunction evidenced by elevation of troponin-T (TnT) and pro-B-type naturietic peptide (proBNP), and electrocardiogram (ECG) abnormalities. We report the clinical course of three children with MIS-C while focusing on the unique atrioventricular (AV) conduction abnormalities. Case #1:19-year-old previously healthy Hispanic male presented with abdominal pain, fever, and non-bloody diarrhea for three days. He was febrile and hypotensive (80/47 mmHg) requiring fluid resuscitation. Symptoms, lab findings, and a positive COVID-19 antibody test were consistent with MIS-C. Methylprednisolone, intravenous immunoglobulin (IVIG), and enoxaparin were started. He required epinephrine for shock and high flow nasal cannula for respiratory distress. Initial echocardiogram demonstrated a left ventricular ejection fraction (LVEF) of 40% with normal appearing coronaries. Troponin and proBNP were 0.41 ng/mL and proBNP 15,301 pg/mL respectively. ECG showed an incomplete right bundle branch block. He eventually became bradycardic to the 30s-50s and cardiac tracing revealed a complete AV block (figure 1a). Isoproterenol, a B1 receptor agonist, supported the severe bradycardia until the patient progressed to a type 2 second degree AV block (figure 1b). A second dose of IVIG was administered improving the rhythm to a type 1 second degree AV block. An IL-6 inhibitor, tocilizumab was given as the rhythm would not improve, and the patient soon converted to a first-degree AV block. Cardiac magnetic resonance imaging showed septal predominant left ventricular hypertrophy and subepicardial enhancement along the basal inferior/anteroseptal walls typical for myocarditis. Case #2: 9-year-old previously healthy Hispanic male presented after three days of daily fevers, headaches, myalgias, diffuse abdominal pain, and ageusia. He was febrile, tachycardic, and hypotensive (68/39 mmHg). Hypotension of 50s/20s mmHg required 3 normal saline boluses of 20 ml/kg and initiation of an epinephrine drip. Severe hypoxia required endotracheal intubation. After the MIS-C diagnosis was made, he was treated with IVIG, mehtylprednisolone, enoxaparin, aspirin, and ceftriaxone. Due to elevated inflammatory markers by day 4 and patient's illness severity, a 7-day course of anakinra was initiated. Initial echocardiogram showed mild tricuspid and mitral regurgitation with a LVEF of 35-40%. Despite anti-inflammatory therapy, troponin and proBNP were 0.33 ng/mL and BNP of 25,335 pg/mL. A second echocardiogram confirmed poor function so milrinone was started. Only, after two doses of anakinra, LVEF soon normalized. Despite that, he progressively became bradycardic to the 50's. QTc was prolonged to 545 ms and worsened to a max of 592 ms. The aforementioned therapies were continued, and the bradycardia and QTc improved to 405 ms. Patient #3: 9-year-old African American male presented with four days of right sided abdominal pain, constipation, and non-bilious non-bloody emesis. He had a negative COVID test and unremarkable ultrasound of the appendix days prior. His history, elevated inflammatory markers, and positive COVID- 19 antibody were indicative of MIS-C. He was started on the appropriate medication regimen. Initial ECG showed sinus rhythm with normal intervals and echocardiogram was unremarkable. Repeat imaging by day three showed a decreased LVEF of 50%. ECG had since changed to a right bundle branch block. Anakinra as started and steroid dosing was increased. By day 5, he became bradycardic to the 50s and progressed to a junctional cardiac rhythm. Cardiac function normalized by day 7, and anakinra was subsequently stopped. Thereafter, heart rates ranged from 38-48 bpm requiring transfer to the pediatric cardiac intensive care unit for better monitoring and potential isoproterenol infusion. He remained well perfused, with continued medical management, heart rates improved. Methods used Retrospective Chart Review. Summary of results Non-specific T-wave, ST segment changes, and premature atrial or ventricular beats are the most often noted ECG anomalies. All patients initially had normal ECGs but developed bradycardia followed by either PR prolongation or QTc elongation. Two had mild LVEF dysfunction prior to developing third degree heart block and/or a junctional escape rhythm;one had moderate LVEF dysfunction that normalized before developing a prolonged QTc. Inflammatory and cardiac markers along with coagulation factors were the highest early in disease course, peak BNP occurred at approximately hospital day 3-4, and patient's typically had their lowest LVEF at day 5-6. Initial ECGs were benign with PR intervals below 200 milliseconds (ms). Collectively the length of time from initial symptom presentation till when ECG abnormalities began tended to be at day 8-9. Patients similarly developed increased QTc intervals later in the hospitalization. When comparing with the CRP and BNP trends, it appeared that the ECG changes (including PR and QTc elongation) occurred after the initial hyperinflammatory response. Conclusions Although the mechanism for COVID-19 induced heart block continues to be studied, it is suspected to be secondary to inflammation and edema of the conduction tissue. Insufficiency of the coronary arterial supply to the AV node and rest of the conduction system also seems to play a role. Although our patients had normal ECG findings, two developed bundle branch blocks prior to more complex rhythms near the peak of inflammatory marker values. Based on the premise that MIS-C is a hyperinflammatory response likely affecting conduction tissue, our group was treated with different regimens of IVIG, steroids, anakinra, and/or tocilizumab. Anakinra, being an IL-1 inhibitor, has been reported to dampen inflammation in viral myocarditis and tocilizumab has improved LVEF in rheumatoid arthritis patients. Based on our small case series, patient's with MISC can have AV nodal conduction abnormalities. The usual cocktail of IVIG and steroids helps;however, when there are more serious cases of cardiac inflammation, adjuvant immunosuppresants like anakinra and toculizumab can be beneficial.

ABSTRACT
Kounis syndrome is defined by the appearance of acute coronary events associated to anaphylactic symptoms. The pathophysiological mechanism is still uncertain, however, coronary vasospastic activity secondary to a hypersensitivity type I response is postulated as a triggering factor. In the con-text of an accident due to a massive bee's attack, poisoning syndrome also occurs, where the poison components directly damage the myocardium. Kounis syndrome has been reported in SARS-CoV-2 infection, opening the possibility of other mechanisms, among which the cytokine storm stands out. This narrative review aims to consider the mechanisms of damage in Kounis syndrome secondary to poisoning by a massive bee attack and its relationship with the development of short-term complications.Copyright © 2023 Universidad de Antioquia.
ABSTRACT
The liver and cardiovascular system disorders are not common in COVID-19 patients, but the patients suffering from these complications are exposed to a higher rate of mortality and disease progression. Hepatic injuries can drive to increased levels of liver enzymes, including ALT, AST, and LDH. Abundant levels of AST, LDH, and CPK can be indicators of cardiac injuries. The current study comparise 366 individuals who are divided into COVID-19 patients and healthy individuals groups, in which we have examined hepatic and cardiac function parameters. Moreover, the clinical characteristics of the participants, ethnicities, and their difference with studied parameters were assessed. The results showed Fars individuals are more susceptible to the disease progression, including liver and heart damage. COVID-19 infection is associated with aging, which indicates that the mean age of the case group is ten years older than the control group (P < 0.001). The blood sugar in the case group (140.50) was higher than in the control group (131.66), although there was no difference between the infection and BS (P = 0.505). Similarly, the increased- mean of the ALT level in the case group (102.369) compared with the control group (68.324) resulted in no significant difference (P = 0.318). Other parameters, including CPK, LDH, and AST showed an increase in the control group values compared to the case group; however, the differences were not significant (P = 0.264, P = 0.795, P = 0.417). Considering the involvement of cardiac and hepatic organs by SARS-CoV-2, paying particular attention to the disorders of these organs through assessing the hepatic and cardiac function parameters can enhance the patient's recovery and survival. However, in this study, we not observed significant differences, except for the Fars people. There is need for further assessment of this issue.
ABSTRACT
Background: Eosinophilic myocarditis is a rare inflammatory cardiomyopathy with a poor prognosis. SARS-CoV-2 (COVID-19) illness has been associated with myocarditis, particularly of lymphocytic etiology. Although there have been cases of eosinophilic myocarditis associated with COVID-19 vaccination, there have been few reported cases secondary to COVID-19 illness, with the majority being diagnosed via post-mortem autopsy. Case: A 44-year-old woman with no significant medical history other than recent COVID-19 illness 6 weeks prior presented with progressive dyspnea. Patient developed acute dyspnea and diffuse pruritic rash after taking hydroxyzine. Labs were significant for mild eosinophilia. Echocardiography showed biventricular systolic dysfunction with left ventricular ejection fraction of 40%, and a moderate pericardial effusion that was drained percutaneously. She underwent left heart and right heart catheterization showing elevated biventricular filling pressures, Fick cardiac index of 1.6 L/min/m2, and no coronary disease. She was started on intravenous diuretics and transferred to our facility for further management. Her course was complicated by cardiogenic shock requiring intra-aortic balloon pump (IABP) support. Mixed venous saturations continued to decline and the patient was placed on veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support. The patient underwent endomyocardial biopsy (EMB) showing marked interstitial infiltration of eosinophils and macrophages with myocyte injury (see image). She was intubated with mechanical ventilation as well due to worsening pulmonary edema and hypoxemia. She was started on intravenous steroids with improvement of hemodynamics and myocardial function and eventually VA- ECMO was decannulated to low-dose inotropic support which in turn was ultimately weaned after 3 days of mechanical support. Conclusion(s): Eosinophilic myocarditis is a rare and under-recognized sequela of acute COVID-19 infection associated with high mortality rates. It requires prompt diagnosis and aggressive supportive care, including temporary mechanical circulatory support. There are few literature-reported cases of COVID-19 myocarditis requiring use of both IABP and VA-ECMO, none of which were used in biopsy-proven eosinophilic myocarditis, with most of these cases resulting in either fatal or unreported outcomes. Most cases of covid myocarditis required IV glucocorticoids therapy in conjunction with IVIG or interferon therapy. Here, we present a rare case of cardiogenic shock secondary to biopsy-proven eosinophilic myocarditis associated with recent COVID-19 illness with a survival outcome after temporary use of IABP and VA-ECMO support, as well as aggressive immunosuppressive therapy.Copyright © 2022
ABSTRACT
Currently, the need for real-time COVID-19 detection methods with minimal tools and cost is an important challenge. The available methods are still difficult to apply, slow, costly, and their accuracy is low. In this work, a novel machine learning-based framework to predict COVID-19 is proposed, which is based on rapid inpatient clinical tests of lung and heart function. Compared with current cognition therapy techniques, the proposed framework can significantly improve the accuracy and time performance of COVID-19 diagnosis without any lab or equipment requirements. In this work, five parameters of clinical testing were adopted;Respiration rate, Heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure. After obtaining results for these tests, a pre-trained intelligent model based on Random Forest Tree (RFT) machine learning algorithm is used for detection. This model was trained by about 13,558 records of the COVID19 testing dataset collected from King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Saudi Arabia. Experiments have shown that the proposed framework performs highly in detecting COVID infections by 96.9%. Its results can be output in minutes, which supports clinical staff in screening COVID-19 patients from their inpatient clinical data. © 2022 IEEE.
ABSTRACT
Cardiovascular disease (CVD) is the leading cause of death in most developed countries, including the United States, with a significant economic impact. Lifestyle changes and the administration of antiplatelet medication, like aspirin, may significantly contribute to the secondary prevention of CVD in adults. For years, aspirin has been utilized for both secondary and primary cardiovascular disease prevention. Aspirin has been extensively used because of the belief that it may have a positive impact on primary prevention, despite the debate surrounding its usage. This study briefly examines usage patterns and discusses the potential variables and factors that can decrease the ability of aspirin to prevent cardiovascular disease. The present study also explore the key studies of aspirin use in the context of recent recommendations. The risk of bleeding has been observed to significantly rise, although large randomized clinical studies have demonstrated a reduction or absence of CVD events. Prevention strategies for cardiovascular disease with low-dose aspirin are no longer advised for persons at intermediate risk. To determine whether taking aspirin is worth the potential dangers, the benefits must be evaluated.Copyright © 2022 Novyi Russkii Universitet. All rights reserved.
ABSTRACT
Artificial intelligence (AI) has shown an immense potential to affect diverse domains of healthcare during the COVID-19 pandemic. The applications of AI in the field of cardiovascular disorders during the COVID-19 pandemic were an added advantage to the cardiologists, as it helped in certain aspects of treatments digitally. This technology is constructive for providing sophisticated treatment in the area of cardiovascular medicine based on technology, because it may assist in assessing and measuring the human heart function. Artificial intelligence employs simulated neuronal program for predicting the survival of a COVID-19 patient affected with heart dysfunction. AI entails intricate algorithms for predicting successful evaluation and therefore the treatment protocol. AI utilizes various methods like cognitive computing, deep learning, and machine learning. It is integrated to make an assessment and determine multifaceted challenges. In humans, cardiovascular disease is still one of the major causes of death, and it is escalating for years together and is also very expensive. AI is employed to recognize new drug treatment and advance the efficacy of a clinician. AI is turning into a well-approved attribute of a variety of engineering and healthcare segments and is being expected to provide a feasible treatment stage. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
ABSTRACT
Objectives: At present, clinicians face plenty of patients complaining of post-COVID-19 chest pain and dyspnea. However, it remains to be seen if these symptoms indicate pathology of the cardiovascular system. We aimed to evaluate heart functions in outpatients with post-COVID-19 chest pain and dyspnea, using 2D speckle-tracking echocardiography (2D-STE). Method(s): This cross-sectional study recruited consecutive patients who presented to cardiology outpatient clinics between June 15, 2021, and July 15, 2021. A total of 78 patients had recovered from COVID-19 1-2 months before admission were included in the study. ECG and echocardiography, including 2D-STE images, were obtained for all patients. Findings were compared with sex- and an age-matched control group of 67 healthy adults. Result(s): The median age was 38 (IQR, 34-45) years, and 64.1% were female. There were no significant differences between the patients and control group regarding laboratory, ECG, and echocardiography findings. Moreover, the left ventricle global longitudinal strain measurements in both the patient and control groups were within the normal ranges and did not show a significant difference (-20.5 [-21.8- -17.9] vs. -19.8 [-21.4-18.9], p=0.894). Conclusion(s): Post-COVID-19 chest pain and dyspnea are unlikely signs of cardiovascular involvement in outpatient young adults who have not been hospitalized with COVID-19.©Copyright 2022 by The Cardiovascular Thoracic Anaesthesia and Intensive Care.
ABSTRACT
Introduction Side effects may occur after vaccination against COVID-19. Temporary reactions such as redness, swelling and pain at the injection site, high temperature, fever, tiredness, etc. may be signs of the body's response to the vaccine. Such reactions usually develop within two days after vaccination and last for a few days. With the growing number of vaccinations against SARSCoV- 2 a rising number of reports also showed serious side effects. In some of the most severe cases, life-threatening thrombotic events may develop. We present a case that shows further symptoms that may be due to an immune reaction to the vaccine. Method In this case report a 67 male smoker presented to our outpatient clinic in April 2022. A few days after vaccination against SARS-CoV-2 with an mRNA vaccine the patient developed pain at all finger tips. The clinical examination showed cool and livid discoloration of all fingers to different degrees;toes were not involved. The symptoms developed progressively over the following weeks into a severe form with progressive fingertip skin necrosis. Results The blood test showed a CRP of 9.18 mg/l (reference range: 0-3 mg/l) as well as an increased fibrinogen and factor VIII activity. D-dimers were only slightly increased to 290 ng/ml (reference range: < 230 ng/ml) during initial examination. Cold agglutinins, cryoglobulin and cryofibrinogen were tested negative. Angiologic examination revealed small multiple thrombi in the ulnar and digital arteries. Furthermore, the resting ECG showed no dilated ventricles and no indication of a hemodynamically relevant defect. The assessment revealed a good cardiac function overall with no evidence of embolism. Therapy was started with Nifidipine (gold standard in Raynaud's disease), Eliquis 5 mg 1-0-1, and diclofenac following hospital admission. In the further course, the therapy regimen was changed to Ilomedin IV for 4 days once a month. After two weeks, symptoms significantly improved and the signs of necrosis at the fingers disappeared. Conclusion In summary, a circulatory perfusion disorder associated with microthrombotic events may be a possible side effect of SARS CoV-2 vaccination. A combination of Nifidipine, DOAC and pain therapy has been shown to be an effective treatment of "COVID-fingers" in this case report.
ABSTRACT
Introduction: Atrial fibrillation (AF) is one of the most common forms of arrhythmia in the clinic. There are about 10 million AF patients in China, of which 1/3 are paroxysmal AF, and the remaining 2/3 are persistent or permanent AF. Long-term AF impairs cardiac function and leads to heart failure and thromboembolism. Moreover, AF increases the risk of mortality and ischemic stroke. Drug therapy and radiofrequency catheter ablation (RFCA) are still the mainstream treatment for AF patients. However, drug therapy has its drawbacks because of the high recurrence rate and side effects. Therefore, the current antiarrhythmic drugs could not meet all the clinical needs of patients with AF. RFCA is superior to antiarrhythmic drugs in maintaining sinus rhythm, improving symptoms and exercise tolerance, and improving quality of life. The role of RFCA in the treatment of persistent AF has gradually been recognized and affirmed. Although RFCA has been progressively used in the treatment of AF, there is still a high recurrence rate of AF after RFCA, especially in patients with persistent AF. Hence, it is meant to solve the high recurrence rate of AF after RFCA. Shensong Yangxin (SSYX) capsule has been proven to treat arrhythmia both in animal studies and clinical research. SSYX capsule could regulate multi-ion channels, improve cardiomyocyte metabolism and regulate autonomic nervous function. In addition, randomized, double-blind, multicenter clinical research indicated that the SSYX capsule exhibited good clinical efficacy in treating ventricular premature beats and paroxysmal AF. However, the effect of SSYX on recurrence after RFCA for patients with persistent AF remains unclear. High-level randomized controlled trials (RCTs) could offer clinicians high-quality evidence regarding the usage of SSYX capsule, especially in persistent AF patients who received RFCA. Hence, the RCTs aim to evaluate the effect of SSYX capsules on the prognosis in patients with persistent AF after RFCA through multicenter, double-blind RCTs. Method(s): This trial will be conducted with a total of 920 participants diagnosed with persistent AF who received RFCA. The participants will be randomized (1:1) into groups receiving either SSYX or Placebo for 1 year. The primary endpoint includes the recurrence of AF within 1 year after RFCA. The secondary outcome measures include changes of AF load at 3 months, 6 months, 9 months, and 1 year after treatment, the time of first atrial flutter/AF, the incidence of cardioversion 1 year after treatment, changes of transthoracic echocardiographic parameters 1 year after treatment, the incidence of stroke and thromboembolism at 6 months and 1 year after treatment, the score of SF-36 within 1 year after treatment. Application: The trial is ongoing. The trial started in September 2019 and recruiting patients. Data collection will be completed after all participants have completed the treatment course and follow-up assessments (expected in 2022, pending COVID-19). Next Steps/Future: The SS-ADJUST study is a randomized control study of TCM in persistent AF after RFCA. It will determine the place of SSYX capsule as a new treatment approach and provide additional and innovative information regarding TCM and the specific use of SSYX in persistent AF after RFCA.
ABSTRACT
Aim: To study the systolic function (SF) and diastolic function (DF) of the heart and to assess subclinical myocardial right ventricular (RV) dysfunction in pts after severe COVID-19. We examined 23 males aged 46-70 years (mean age - 58.8 +/- 12.6 yrs) discharged after COVID-19 (50-75% of the parenchymal damage) with exertional dyspnea. We performed transthoracic echocardiography (TTE) with assessment of RV global longitudinal strain (RV-GLS) and right ventricular free wall longitudinal strain (RVLS) using speckle tracking echocardiography. Result(s): The SF of the RV assessed by the excursion of the tricuspid valve ring (TAPSE) was preserved (2.1 +/- 0.6 cm) in all pts under study after severe COVID-19. The left ventricular (LV) ejection fraction was also preserved (62.1 +/- 4.7%) in all pts. TTE revealed normal ventricular and atrial dimensions: LV end-diastolic volume index (62.5 +/- 8.4 ml/m2) and RV end-diastolic diameter (2.7 +/- 0.6 cm), left atrial (LA) volume index (26.7 +/- 3.1 ml/m2) and right atrial (RA) volume index (20.2 +/- 4.5 ml/m2). LV DD was also detected: Grade I in 17 (74%) pts, and Grade II in 6 (16%) pts. Moderate pulmonary hypertension (PH) was present in all pts (time of acceleration of systolic flow in the pulmonary artery (AcT - 85.0 +/- 7.9 msec) as a consequence of significant pulmonary parenchymal involvement. We found reduced RV-GLS (-17.4 +/- 2.7%) and free wall RVLS (-18.9 +/- 3.1%) in 23 (100%) pts. Conclusion(s): Preserved LV and RV SF with Grade 1 and Grade 2 LV DD and moderate PH were established in pts after severe COVID-19. RV wall motion abnormalities with reduced RV-GLS and free wall RVLS were found, indicating the presence of subclinical RV myocardial dysfunction.
ABSTRACT
Introduction: Long COVID-19, defined as symptom persistence beyond 3 months without alternative diagnosis after recovery, generates cardiorespiratory sequelae that are not yet well elucidated. This study aimed to assess, through spirometry and 6MWT, deficiency of patients who recovered from COVID-19. Method(s): Eighty patients (age>30 years) were included. Anthropometric (age, body mass index (BMI)), spirometric (FEV1, FVC and FEV1/FVC), and 6MWT (6-min walk distance (6MWD), heart-rate (HR), pulsed haemoglobin saturation in oxygen (SpO2), dyspnoea (visual analogous scale (VAS)) data were collected. Applied definitions were: abnormal 6MWD (< lower limit of normal), desaturation (fall in SpO2>5%), abnormal dyspnoea (VAS after 6MWT>5), chronotropic insufficiency (HR after 6MWT<60%), excessive cardiac response (HR after 6MWT>80%). Result(s): Age and BMI medians were 61years and 28.4kg/m2, respectively. FEV1, FVC, and FEV1/FVC means+/-SD were 84+/-16%, 91+/-14%, and 0.79+/-0.08, respectively. 6MWD, HR, and resting VAS means+/-SD were 571+/-79m (97+/-15%), 78+/-11bpm (46+/-7%), and 1+/-1, respectively. After 6MWT, HR and VAS were statistically increased (115+/-24bpm (67+/-14%) and 3+/-2, respectively). Mean resting SpO2 was 96.5+/-1.9% and it increased significantly to 94.7+/-4.4% after 6MWT. Ten (12.5%) patients presented desaturation. After 6MWT, 15 (19%), 23 (29%), 11 (14%), and 4 (5%) patients had abnormal 6MWD, chronotropic insufficiency, excessive cardiac response, and abnormal dyspnoea, respectively. Conclusion(s): Long COVID-19 patients seem to have altered submaximal aerobic capacity, and are likely to develop long-term pulmonary and cardiac impairments. A respiratory rehabilitation program could help restore this incapacity.
ABSTRACT
Clinical data and follow-up of a case of congenital disorder of glycosylation type Ia (CDG-Ia) combined with dilated cardiomyopathy admitted to the Department of Cardiology, Children's Hospital of Nanjing Medical University were analyzed retrospectively.The 5-year-old female patient was admitted in December 2016 due to recu-rrent shortness of breath for 2 months.Clinical symptoms and signs included repeated attacks of shortness of breath, physical retardation, malnutrition, binocular esotropia, multiple episodes of hypoglycemia, hepatosplenomegaly, hypotonia and other multi-system damages.Cardiac echocardiography suggested the feature of dilated cardiomyopathy, including the significant enlargement of the left ventricle, and decreased systolic function.Genetic testing revealed a compound heterozygous mutation in the PMM2 gene, and as a result, the patient was diagnosed as CDG-Ia.The patient's condition improved after symptomatic treatments such as Cedilanid, Dopamine, Dobutamine, Furosemide, as well as support treatments like myocardium nutrition, blood sugar maintenance, liver protection, etc.After discharge, the patient was given oral Digoxin, Betaloc, Captopril and diuretics, and hypoglycemia-controlling agents.The patient was followed up every 3-6 months.After more than 2 years of follow-up, the heart function and heart enlargement gradually returned to normal.During the Corona Virus Disease 2019 outbreak, self-withdrawal continued for 2 months.Re-examinations showed decreased cardiac function and enlarged left ventricle again.Medications were resumed again, and the patient was followed up closely.This case report suggested that CDG-Ia may be associated with dilated cardiomyopathy, and the cardiac phenotype may be improved by symptomatic supportive treatment.Copyright © 2021 by the Chinese Medical Association.
