<sec> <title>BACKGROUND</title> Lifelong anticoagulation with vitamin K antagonists is required to prevent prosthetic valve thrombosis after mechanical aortic replacement (MAVR). Current guidelines recommend a standard international normalized ratio (INR) of 2.5 for MAVR patients without additional thromboembolic risk factors, while higher INR 3.0 advised those conditions such as atrial fibrillation, prior thromboembolism, or left ventricular dysfunction. However, limited clinical data exist...

. Currently, the literature regarding management of COVID-19 induced cardiomyopathy with reduced ejection fraction is limited. In this case report, we present first documented myocardial stunning leading to severely LV systolic function that was reversed by administration corticosteroids and tocilizumab.

The extent to which cytochrome P450 (CYP) 2C19 genotype influences the effectiveness of clopidogrel remains uncertain due considerable heterogeneity between studies. We used polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method for genotyping loss function (LOF) allele, CYP2C19*2 and gain (GOF) CYP2C19*17 in 163 patients undergoing PCI 165 healthy volunteers from an ethnically distinctive Bangladeshi population. Thirty-eight took prasugrel 125 among whom 30 had...

Abstract Background Previous studies have compared Impella use to intra‐aortic balloon pump (IABP) in patients with acute myocardial infarction and cardiogenic shock (AMI‐CS) undergoing percutaneous coronary intervention (PCI). Our objective was compare clinical outcomes AMI‐CS PCI who received (percutaneous left ventricular assist device) without vasopressors, IABP vasopressors mechanical circulatory support (MCS). Methods We queried the National Inpatient Sample (NIS) using ICD‐10 codes...
