It is unclear whether long-term heavy alcohol use leads to early cardiac function decline. This study aimed to investigate the relationship between heavy alcohol use and reduced cardiac function in subclinical status, using myocardial work analysis. The results showed that epicardial adipose tissue volume and serum biomarkers were potential factors in predicting early cardiac function decline.
BackgroundIt is unclear whether long-term heavy alcohol use leads to early cardiac function decline.HypothesisLong-term heavy alcohol use developed reduced cardiac function in subclinical status by analyzing myocardial work (MW). Epicardial adipose tissue (EAT) volume and serum biomarkers contribute to identify potential factors sensitive in predicting early cardiac function decline.MethodsWe enrolled 31 asymptomatic participants with heavy alcohol use and 33 age and sex-matching nondrinking individuals. Participants underwent echocardiography, MW analysis, EAT volume measurement, serum biochemical examinations, and body composition assessment. We used multivariate linear regression to identify correlation between MW and total cholesterol (TC), EAT volume, and placental growth factor (PlGF). To determine global work efficiency (GWE) below the normal reference value of 96%, we developed receiver operating curves with area under curve (AUC) to compare different combinations of TC, EAT volume, and PlGF.ResultsAll 64 participants were male. GWE was reduced in the alcohol use group compared with the control group (96, interquartile range [IQR] = [95-97.75] vs. 97, IQR = [97-98], p = .004). TC was positively associated with GWE (& beta; = .434, 95% confidence interval [CI] = 0.228 to 1.328, p = .008), whereas EAT volume (& beta; = -.398, 95% CI = -0.000446 to -0.000093, p = .005) and PlGF (& beta; = -.493, 95% CI = -1.010 to -0.230, p = .004) were inversely associated with GWE. The most significant AUC for reduced GWE was TC + EAT volume (0.851, 95% CI = 0.671 to 1, p = .006).ConclusionAsymptomatic heavy alcohol use has shown early reduced cardiac function which can be associated with altered fat metabolism, suggesting individuals with alcohol use and abnormal fat metabolism need to be alert to heart damage. This cross-sectional study showed that participants with heavy alcohol use but no cardiovascular disease symtoms experienced lower GWE than the control group, and the GWE correlated with TC, EAT volume, and PlGF. TC combined with EAT volume had a satisfactory prediction effect for GWE under 96% among all participants.image
