Abstract 17334: Effects of Alcohol Consumption on Fiver-Year Change in Cardiac Structure and Function: In the Echocardiographic Study of Latinos

Abstract

Background: The relationship between alcohol consumption and clinical heart failure has been extensively studied. There have been little longitudinal data documenting alcohol effects on cardiac structure and function in a community-based population. Methods: The second Echocardiographic Study of Latinos (ECHO-SOL2) was designed to provide echocardiographic parameters that characterized longitudinal cardiac structure and function in a random and representative sample of 1,818 participants ≥45 years old. Participants underwent to serial echocardiograms at 2011-2014 (exam 1) and ~5-6 years later at 2016-2019 (exam 2). Quantification of alcohol was created on a gender-specific basis. Multiple linear regression models were adjusted for age and sex. Results: The mean age at enrollment was 56.4 years old, 57% were women. At baseline, impaired left ventricular (LV) systolic function and increased right ventricular (RV) function were associated with binge drinkers (P = 0.01). At 5-6 years later, heavy drinkers had a significant decrease in LV ejection fraction (P = 0.01). Moderate and binge drinkers demonstrated worsening diastolic function over time (P ≤ 0.01). Binge drinkers demonstrated a progressive decrease in LV mass index (P = 0.02), decrease in LV stroke volume (P = 0.01) and further reduction in RV function (P < 0.01). Conclusion: Alcohol consumption was associated with longitudinal changes in cardiac structure and function, mostly among binge drinkers, which can lead to impaired myocardial contractility compared to nondrinkers.
