22,187 | Amiodarone vs. metoprolol succinate in HFrEF complicated with persistent atrial fibrillation with rapid ventricular response: A prospective observational study. | β-blockers have been recommended for patients with heart failure (HF) and atrial fibrillation (AF), but studies have shown that β-blockers do not reduce all-cause mortality or cardiovascular mortality in patients with HF and AF.</AbstractText>To investigate the difference in efficacy between oral amiodarone... |
22,188 | Staging Heart Failure Patients With Secondary Mitral Regurgitation Undergoing Transcatheter Edge-to-Edge Repair. | Secondary mitral regurgitation (SMR) is a progressive disease with characteristic pathophysiological changes that may influence prognosis. Although the staging of SMR patients suffering from heart failure with reduced ejection fraction (HFrEF) according to extramitral cardiac involvement has prognostic value in medical... |
22,189 | Can we explore AF-pacemakers' relationship using clinical and echocardiographic parameters in patients with permanent pacemaker? (Echocardiography and subclinical AF in permanent pacemaker). | Patients on implanted permanent pacemakers frequently develop atrial fibrillation (AF). We aimed to determine the Echocardiographic and clinical parameters predicting AF in patients with a dual-chamber (DDD) pacemaker. This retrospective study included 208 patients with permanent pacemaker, classified according to deve... |
22,190 | Incidence of arrhythmias in COVID-19 patients with double mutant strain of SARS-CoV-2 virus: A tertiary care experience. | <b>Background:</b> Our understanding of arrhythmias is minimal with SARS-CoV-2 virus and with the emergence of its double mutant, virtually nonexistent. Patients with the double mutant (B.1.617) SARS-CoV infection had more cardiac manifestations, including arrhythmias and sudden death, than with the traditional variant... |
22,191 | Rare Occurrence of Apical Hypertrophic Cardiomyopathy Among Hispanics. | Apical hypertrophic cardiomyopathy (ApHCM), also known as Yamaguchi syndrome represents an uncommon morphologic variant of hypertrophic cardiomyopathy (HCM) in which the myocardial hypertrophy predominantly involves the apex of the left ventricle (LV). It is exemplified by "giant" negative precordial T-waves on electro... |
22,192 | Anthracycline-Induced Cardiotoxicity in Breast Cancer Patients: A Five-Year Retrospective Study in 10 Centers. | Cardiotoxicity as a result of anthracycline chemotherapy has been linked to increased morbidity and mortality in breast cancer patients. There is a need for early detection through risk factor identification. To date, no large multicenter study has been conducted to describe the incidence, risk factors and clinical and... |
22,193 | Long-term outcomes and risk factors for mortality of patients with hypertrophic obstructive cardiomyopathy undergoing septal myectomy. | We aimed to evaluate the long-term surgical outcomes of patients with hypertrophic obstructive cardiomyopathy and explore the risk factors for mortality, especially those related to atrial fibrillation.</AbstractText>We retrospectively reviewed 150 consecutive patients with hypertrophic obstructive cardiomyopathy who u... |
22,194 | [A case of aconitum kusnezoffii intoxication with severe arrhythmia]. | Aconitum kusnezoffii is a traditional Chinese medicine of Ranunculaceae family. Its toxicity is relatively strong, and its dosage is similar to that of poisoning. In clinical practice, poisoning events are often caused by excessive dosage or improper use. There is no specific antidote for kusnezoff root poisoning. Seve... |
22,195 | Electrocardiogram QRS Complex Duration as a Predictor of Hospital Prognosis in Patients With COVID-19. | Aim      To determine the effect of major electrocardiographic (ECG) parameters on the prognosis of patients with COVID-19.Material and methods  One of systemic manifestations of COVID-19 is heart injury. ECG is the most simple and available method for diagnosing the heart injury, which in... |
22,196 | Trabectedin Cardiotoxicity in Soft Tissue Sarcoma: A Case Series and Clinical Insights. | Trabectedin is a chemotherapeutic used to treat advanced soft tissue sarcoma and relapsed platinum-sensitive ovarian cancer. Although it is associated with a low incidence of cardiotoxicity, when this occurs it can be fatal or significantly compromise the quality of life in patients with advanced cancer. Here, we prese... |
22,197 | Exercise-Induced Ischemic ST-Segment Elevation in Anomalous Origin of the Right Coronary Artery From the Left Sinus of Valsalva With an Intramural Course and Blocked Coronary Bypass. | Sudden cardiac events in young athletes are a major concern in the field of sports cardiology. Although coronary artery anomalies remain a major cause of cardiac events in young athletes, only a few cases have been diagnosed prior to critical events. Here, we present the case of a previously asymptomatic young male run... |
