Daily moderate alcohol consumption may put your heart health at risk as it increases your risk of irregular heart rhythm condition.

‘Drinking moderate alcohol on a regular basis leads to more scarring and impairment in electrical signaling of heart when compared with non-drinkers and light drinkers.

Alcohol consumption is, therefore, an important modifiable risk factor for atrial fibrillation an abnormal heart rhythm characterized by a rapid and irregular beating of atria upper chamber of the heart, the researchers said. Read More..





"Regular moderate alcohol consumption, but not mild consumption, is an important modifiable risk factor for atrial fibrillation associated with lower atrial voltage and conduction slowing," said lead investigator Peter Kistler, Professor from the Heart Centre at Alfred Hospital.
"These electrical and structural changes may explain the propensity to atrial fibrillation in regular drinkers. It is an important reminder for clinicians who are caring for such patients to ask about alcohol consumption and provide appropriate counseling in those who over-indulge," he added.
In the study, the team determined the impact of different degrees of alcohol consumption on atrial remodeling using high-density electroanatomic mapping.
They performed detailed invasive testing on the atria of 75 patients with atrial fibrillation, 25 in each of three categories: life-long non-drinkers, mild drinkers, and moderate drinkers.
