Alcoholic cardiomyopathy and cardiovascular events - an insight from the Liptov region

Area of Science:

• Cardiology
• Alcohol-related research
• Clinical investigation

Background:

• Heavy alcohol consumption is a known risk factor for cardiovascular disease.
• Understanding the specific impact on cardiac structure and function is crucial for public health.
• Previous studies show varied results on the direct effects of heavy drinking on the heart.

Purpose of the Study:

• To investigate the association between heavy alcohol consumption (≥80g/day) and cardiovascular events.
• To evaluate echocardiographic parameters in heavy alcohol consumers.
• To compare cardiovascular outcomes in individuals with different daily alcohol intake levels over 4 years.

Main Methods:

• 100 heavy alcohol consumers (≥80g/day) without pre-existing cardiovascular disease were recruited.
• Participants were divided into two groups based on daily alcohol intake.
• A 4-year follow-up included clinical evaluation, echocardiography, biochemical analysis, and monitoring for cardiovascular events and rhythm disorders.

Main Results:

• No significant differences were observed in ejection fraction (EF) or left atrium diameter (LA) between groups.
• Left ventricular end-diastolic diameter (LVEDD) showed a non-significant trend towards being larger in the higher intake group (p=0.09).
• No significant differences were found in the incidence of diabetes mellitus, heart failure, atrial fibrillation, stroke, delirium, or myocardial infarction between the groups.

Conclusions:

• Heavy alcohol consumption, even at doses ≥80g/day, did not lead to significant differences in echocardiographic parameters or cardiovascular events over 4 years.
• The study suggests that within the studied heavy drinking population, cardiac function and event rates were comparable.
• Further research may be needed to explore potential long-term or subtle effects not captured in this cohort.
