Moderate alcohol consumption which is defined as 8 to 21 drinks per week has been found to be a predictor of heart atrial remodeling by reducing both atrial voltage and conduction. What does this mean ?

This alcohol drinking was associated with electrical and structural changes in the heart myocardium in patients who had electrophysiological studies prior to ablation.

All in all, it means that alcohol has a direct effect on the atrial substrate. It means that alcohol is implicated in atrial fibrillation pathogenesis. This makes it a risk factor. We always knew that alcohol was implicated in cardiomyopathy and also in holiday heart syndrome where atrial fibrillation occurs at the holiday times due to excessive sugar and alcohol.

This is more evidence that alcohol damages the heart muscle

Until tomorrow…
