A study published in the journal Clinical Nutrition evaluated the association between alcohol consumption and coronary artery disease severity.
The cross-sectional study of patients undergoing coronary angiography assessed the age, cardiovascular risk factors (smoking, systemic arterial hypertension, dyslipidemia and diabetes) and alcohol drinking habits of participants. Alcohol consumption was divided in three categories: nondrinker, moderate alcohol consumption (less than 15g ethanol/day for women or 30 g ethanol/day for men) and heavy alcohol consumption. Coronary artery disease severity was assessed through the Friesinger Score (FS) in the coronary angiography, by interventional cardiologists blinded to alcohol consumption.
The final sample included 363 adults; of those, 228 were men (62.81%) with a mean age of 60.5 ± 10.9 y. Unadjusted analyses identified that the main covariates associated with the Friesinger score were sex, age, hypertension, diabetes, dyslipidemia and alcohol consumption. Lower Friesinger scores were also observed in moderate alcohol consumption when comparing to those who do not drink (RR 0.86; 95% CI 0.79-0.95).
The study concludes that, among patients with suspected coronary artery disease undergoing coronary angiography, moderate alcohol consumption is associated to a lower coronary artery disease severity than heavy drinking.
