The ingestion of small to moderate alcohol consumption amounts has been associated to cardiovascular protection. This study aimed to evaluate the association between alcohol consumption and coronary artery disease severity. MATERIAL AND


Cross-sectional Study with patients undergoing coronary angiography. Age, cardiovascular risk factors (smoking, systemic arterial hypertension, dyslipidemia and diabetes) and alcohol drinking habit were investigated. Alcohol consumption was divided in three categories nondrinker, moderate alcohol consumption (less than 15 g 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%). Mean age was 60.5 ± 10.9 y. Unadjusted analyses identified sex, age, hypertension, diabetes, dyslipidemia and alcohol consumption as the main covariates associated with the Friesinger score. 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).


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.
