Reducing alcohol consumption can improve cardiovascular health drastically and reduce the risk of coronary artery disease even among light drinkers, a new study has found

"These new results are critically important to our understanding of how alcohol affects heart disease. Contrary to what earlier reports have shown, it now appears that any exposure to alcohol has a negative impact upon heart health," says co-lead author Michael Holmes, MD, PhD, research assistant professor in the department of Transplant Surgery at the Perelman School of Medicine at the University of Pennsylvania. "For some time, observational studies have suggested that only heavy drinking was detrimental to cardiovascular health, and that light consumption may actually be beneficial. This has led some people to drink moderately based on the belief that it would lower their risk of heart disease. However, what we're seeing with this new study, which uses an investigative approach similar to a randomized clinical trial, is that reduced consumption of alcohol, even for light-to-moderate drinkers, may lead to improved cardiovascular health."
In the new study, researchers examined the cardiovascular health of individuals who carry a genetic variant of the 'alcohol dehydrogenase 1B' gene, which is known to breakdown alcohol at a quicker pace. This rapid breakdown causes unpleasant symptoms including nausea and facial flushing, and has been found to lead to lower levels of alcohol consumption over time. By using this genetic marker as an indicator of lower alcohol consumption, the research team was able to identify links between these individuals and improved cardiovascular health.
