Intracranial Hemorrhage Induced Takotsubo Cardiomyopathy: A Case Report.

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is a reversible cardiac disorder characterized by left ventricular dysfunction without significant obstructive coronary artery disease. It is classically secondary to emotional stress in postmenopausal women but can also be secondary to physical stress. This report presents a unique case of takotsubo cardiomyopathy induced by intracranial hemorrhage in an 80-year-old female who presented with syncope.

Analysis of STEMI and NSTEMI in a Community Cohort of Marijuana Users.

Background: Marijuana is the most commonly used illicit drug in the United States. Current research has yet to come to a consensus on its association with acute coronary syndrome (ACS). Herein, we aimed to analyze how marijuana use relates to acute ST elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI).

A Rare Case of Resolution of High-Degree Atrioventricular Block Associated With COVID-19.

Cardiac arrhythmias have been reported in the setting of coronavirus disease 2019 (COVID-19) infection. To date various tachyarrhythmias have been noted. This case report describes an atypical clinical hospitalization course of high-degree atrioventricular (AV) block in the setting of COVID-19 infection which required no intervention.

Right Heart Transvalvular Embolus with High Risk Pulmonary Embolism in a Recently Hospitalized Patient: A Case Report of a Therapeutic Challenge.

Thrombus-in-transit is not uncommon in pulmonary embolism but Right Heart Transvalvular Embolus (RHTVE) complicating this is rare. A 54-year-old obese male with recent hospitalization presented with severe dyspnea and collapse. Initial investigations revealed elevated d-dimer and troponin.

Obstructive sleep apnea and dyslipidemia: evidence and underlying mechanism.

Introduction: Over the past half century, evidence has been accumulating on the emergence of obstructive sleep apnea (OSA), the most prevalent sleep-disordered breathing, as a major risk factor for cardiovascular disease. A significant body of research has been focused on elucidating the complex interplay between OSA and cardiovascular risk factors, including dyslipidemia, obesity, hypertension, and diabetes mellitus that portend increased morbidity and mortality in susceptible individuals.

Conclusion: Although a clear causal relationship of OSA and dyslipidemia is yet to be demonstrated, there is increasing evidence that chronic intermittent hypoxia, a major component of OSA, is independently associated and possibly the root cause of the dyslipidemia via the generation of stearoyl-coenzyme A desaturase-1 and reactive oxygen species, peroxidation of lipids, and sympathetic system dysfunction.
