Key result
Moderate caffeine intake is not associated with increased risk of arrhythmias or cardiovascular events.
Why the study?
While caffeine's effects on the cardiovascular system have been extensively studied, controversy remains surrounding its potential risks, particularly in patients with heart disease.
Does caffeine consumption increase the risk of arrhythmias and adverse cardiovascular events in the general population and high-risk patients?
Does caffeine consumption increase the risk of arrhythmias and adverse cardiovascular events in the general population and high-risk patients?
This review highlights that while moderate caffeine consumption is generally safe and potentially protective against cardiovascular disease, excessive intake can be proarrhythmic and increase cardiovascular risk.

Supports moderate caffeine intake for most; leaves open arrhythmia risks in susceptible subgroups for prospective trials.
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. The proarrhythmic potential of caffeine, particularly on atrial fibrillation and ventricular arrhythmias, is conducted. It explains the mechanism of action, including adenosine receptor antagonism, phosphodiesterase inhibition, calcium mobilization, and catecholamine release of caffeine. Epidemiological evidence and mechanistic insights are provided for both conditions, and caffeine consumption's incidence, triggers, and impact on premature ventricular contractions are explained. It emphasizes the need for more research to comprehend the complex relationship between caffeine consumption and cardiovascular health, specifically in high-risk populations.

Adel Khalifa Sultan Hamad (2024) conducted a review in Cardiovascular disease and arrhythmias. Caffeine was evaluated. Current evidence suggests that moderate caffeine intake does not significantly increase the risk of cardiovascular issues or arrhythmias for most individuals.
