Extended anterior myocardial infarction (MI) is frequently followed by left ventricular (LV) remodeling ensuing in heart failure and aneurysmatic transformation of the infarcted myocardial segment. Therapies that attenuate or reverse pathological LV remodeling have been shown to improve functional status and outcomes. This case reports our recent experience with a ...

Because the systemic and pulmonary circulations are arranged in series, the right and left ventricles of the human heart have similar stroke volumes (with only minute beat-to-beat changes). Besides propelling the same volume of blood through the corresponding circulations, the two ventricles also share common structures such as the pericardium, ...

The purpose of this study is to investigate if the prescription of proton-pump inhibitors (PPIs) was associated with a sudden risk of acute myocardial infarction (AMI) while controlling for time-invariant confounding by using a case-crossover design. An association might indicate that physicians take prodromal symptoms of myocardial ischaemia for dyspepsia. ...

The phenomenon of warm-up angina was first noted over 200 years ago. It describes the curious observation whereby exercise-induced ischaemia on second effort is significantly reduced or even abolished if separated from first effort by a brief rest period. However, the precise mechanism via which this cardio-protection occurs remains uncertain. Three ...

Intravenous amiodarone is one of the most widely used antiarrythmics for the treatment of atrial fibrillation with rapid ventricular response. Peripheral amiodarone infusion, however, often causes pain during infusion and subsequent phlebitis.Data collection on a cardiac telemetry unit revealed a high rate of phlebitis. A multidisciplinary team developed and implemented ...

Atrial fibrillation (AF) is the most common form of arrhythmia, currently estimated to affect over 33 million individuals worldwide. The incidence of AF continues to grow, and unfortunately current treatment strategies (e.g., catheter ablation, ion channel blockers) may have limited efficacy and/or adverse effects. Thus, understanding the underlying source(s) of ...

Editorial Comment; Non-ischemic cardiomyopathy (NICM) is characterized by myocardial dysfunction in the absence of significant coronary artery disease. Myocardial cellular replacement by scar tissue leads to further mechanical dysfunction as well as ventricular tachycardia (VT) in some of these patients. The heterogeneous and often complex substrate distribution in such cases ...

-Despite the increasing prevalence of heart failure (HF) with preserved ejection fraction (HFpEF) in humans, there remains no therapeutic options for HFpEF. Adiponectin (APN), an adipocyte-derived cytokine exerts cardioprotective actions and its deficiency is implicated in the development of hypertension and HF with reduced ejection fraction. Similarly APN deficiency in ...
