Key result
Tobacco and alcohol use linked to atrial myocardial alterations driving atrial cardiomyopathy, AF, and stroke.
Why the study?
Tobacco smoking and alcohol consumption are recognized cardiovascular risk factors associated with atrial dysfunction, but the pathogenesis involving alterations in the atrial myocardium is complex and multifactorial.
Tobacco smoking and alcohol consumption are associated with alterations in the atrial myocardium, contributing to atrial cardiomyopathy, atrial fibrillation, and stroke.
Tobacco smoking and alcohol consumption are widespread exposures that are legal and socially accepted in many societies. Both have been widely recognized as important risk factors for diseases in all vital organ systems including cardiovascular diseases, and with clinical manifestations that are associated with atrial dysfunction, so-called atrial cardiomyopathy, especially atrial fibrillation and stroke. The pathogenesis of atrial cardiomyopathy, atrial fibrillation, and stroke in context with smoking and alcohol consumption is complex and multifactorial, involving pathophysiological mechanisms, environmental, and societal aspects. This narrative review summarizes the current literature regarding alterations in the atrial myocardium that is associated with smoking and alcohol.

Ohlrogge et al. (2022) conducted a review in Atrial cardiomyopathy, atrial fibrillation, and stroke. Tobacco smoking and alcohol consumption was evaluated on Alterations in the atrial myocardium. Tobacco smoking and alcohol consumption are associated with alterations in the atrial myocardium that contribute to atrial cardiomyopathy, atrial fibrillation, and stroke.
