“…4 PACs may result from non-cardiac (chronic and acute pulmonary disease, chronic renal failure, neurological disorders) or cardiac diseases (acute myocardial infarction, coronary artery disease, valvular heart diseases, and cardiomyopathy) As well as behavioral/ other (like alcohol, theophylline, caffeine, smoking, and thyroid conditions). 2 Possible causes of PVCs are categorized as cardiac, pulmonary, endocrinopathies, and behavioral/other factors. Cardiac causes include heart failure, acute myocardial infarction, hypertension with left ventricular hypertrophy, hypertrophic cardiomyopathy, congenital heart disease, and idiopathic ventricular tachycardia.…”

“…Premature cardiac contractions, also known as atrial and ventricular ectopic beats, are ectopic heart rhythm disorders in the general population 1 . They arise when ectopic impulses from the muscle fiber or fibers within the ventricles or atriums occur independently of the physiological pacemakers 2 . Based on the origin of these ectopic beats, we classified them as premature atrial contractions (PACs) and premature ventricular contractions (PVCs) 3 .…”

“…Endocrinopathies involve thyroid, adrenal, and gonadal abnormalities. Behavioral and other factors consist of nicotine, caffeine, alcohol, sympathomimetic agents (e.g., beta‐agonists, antihistamines), and illicit drugs (e.g., cocaine, amphetamines) 2 . The different etiologies of PAC and PVC are shown in Table 1.…”

Background and AimsPremature atrial contractions (PACs) and premature ventricular contractions (PVCs) are ectopic heart rhythm disorders with implications for cardiovascular health. This study explores the relationship between caffeine consumption and the risk of PACs and PVCs, with a focus on healthcare workers, such as doctors, nurses, pharmacists, and midwives, who often rely on caffeine to combat fatigue, especially during night shifts.MethodsA thorough review was conducted through PubMed, Scopus, Google Scholar, and Web of Science, utilizing a combination of MeSH terms and keywords. Studies examining the link between caffeine consumption and PACs and PVCs, particularly in healthcare workers, were included.ResultsWe found that caffeine shows various effects based on dosage and can impact arrhythmia risk. Individuals working long shifts, including healthcare professionals, are prone to increased caffeine intake, leading to higher cardiovascular risk. To mitigate these risks, tailored guidelines for caffeine consumption, flexible shift scheduling, and mental health support services are recommended. Promoting caffeine alternatives within healthcare institutions can be beneficial.ConclusionAlthough caffeine may have potential benefits, its drawbacks, particularly concerning cardiovascular health, may surpass its advantages, especially when consumed in high doses. A multidisciplinary approach is crucial for healthcare workers’ well‐being and quality of patient care. Further research is required to refine and support these recommendations.
