Light-to-moderate alcohol consumption is believed to be protective against coronary artery disease (CAD) in many studies. However, the cardioprotective effects of alcohol intake lack epidemiologic evidence in a Chinese population.
The present case–control study was designed to explore the relation between alcohol consumption and angiographically proved CAD in Chinese men.
The study population consisted of 1,476 consecutive men 36 to 84 years of age who underwent coronary arteriography. Participants were categorized as nondrinkers, light drinkers, moderate drinkers, and heavy drinkers.
Adjusted odds ratios for light, moderate, and heavy drinking were 1.16 (95% confidence interval 0.68 to 1.94), 1.78 (1.35 to 2.27), and 2.18 (1.46 to 3.25). Adjusted odds ratios were 1.36 (1.08 to 1.83) for drinking alcohol 2 to 3 days/week, 1.58 (1.17 to 2.26) for 4 to 5 days/week, and 2.03 (1.36 to 3.27) for 6 to 7 days/week.
Compared to nondrinking, adjusted odds ratios were 1.03 (0.54 to 1.87) for drinking 0 to 15 years, 1.61 (1.28 to 2.14) for 16 to 30 years, and 1.98 (1.23 to 3.05) for >30 years.
In conclusion, moderate-to-heavy alcohol consumption increased the risk of CAD in Chinese men. CAD risk tended to increase with an increase in frequency and duration of drinking.
