Caffeine and Arrhythmias: A Critical Analysis of Cardiovascular Responses and Arrhythmia Susceptibility.

Caffeine is a frequently consumed stimulant in different foods and beverages: coffee, tea, chocolate, sodas, and energy drinks. While its effects on the cardiovascular system have been extensively studied, there remains controversy surrounding its potential risks, particularly in patients with heart disease. This review provides a complete overview of caffeine's pharmacological properties, sources, and cardiovascular effects, particularly emphasizing its arrhythmogenic potential.

Environmental Factors, Occupational Hazards, and Seasonal Changes: Unveiling the Triggers of Atrial Fibrillation.

Introduction: Atrial Fibrillation (AF) is the most common cardiac arrhythmia in the world, with a lifetime risk of 26% for men and 23% for women. Atrial fibrillation is a prevalent cardiac arrhythmia that is more common with increasing age. Globally, around 33.

Clinical Evidences and Pathophysiology of Cardiac Arrhythmia in the Era of Coronavirus Disease-2019.

The coronavirus disease-2019 (COVID-19) is primarily caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has been a challenge to the clinician. Epidemiological studies unveiled the involvement of the cardiovascular system during the course of SARS-CoV-2 infection. The cardiac complications in patients with COVID-19 include myocarditis, heart failure, acute coronary syndrome, and cardiac arrhythmia.

New Technologies for Detection and Management of Atrial Fibrillation.

Atrial fibrillation (AF) is a common and prevalent form of arrhythmia. It is associated with various morbidities with stroke being the major hazard. Since AF is often reported to be asymptomatic, many individuals remain unaware of their condition and may not receive the requisite treatment.

The Gulf Implantable Cardioverter-defibrillator Registry: Rationale, Methodology, and Implementation.

Background: The implantable cardioverter-defibrillator (ICD) is effective in the prevention of sudden cardiac death in high-risk patients. Little is known about ICD use in the Arabian Gulf. We designed a study to describe the characteristics and outcomes of patients receiving ICDs in the Arab Gulf region.
