Background Acute coronary syndrome (ACS) remains a risk factor for heart failure (HF). Therefore, we aimed to assess the cardioprotective role of sodium–glucose cotransporter-2 (SGLT2) inhibitors post-ACS in patients with acute HF (AHF) and diabetes. Methods We conducted retrospective observational cohort study employing propensity score matching. This involved diabetes admitted ACS complicated by AHF, defined as either new clinical requiring diuretics during index admission or having an...

Introduction: Patients with acute coronary syndrome (ACS) have an unmet need for further risk reduction in major adverse cardiovascular events (MACE) and heart failure (HF) development despite guideline-directed medical therapy. As sodium glucose cotransporter-2 inhibitors (SGLT2i) are cardioprotective, this study, we assessed the effectiveness of SGLT2i post-ACS new onset HF. Hypothesis: use improves outcomes induced Methods: We conducted a retrospective observational cohort study that...

Electrocardiogram (ECG) is a reliable tool in the initial diagnostic workup of patients presenting to Emergency Department (ED). However, it not totally free interference from artifacts due various causes such as positional changes during capture, muscle contractions, limb tremors, etc., Such can have disastrous complications if they mimic arrhythmias and are treated such. This case report describes two catheterization laboratory (Cath lab) setting who developed ECG mimicking ventricular...
