Even in moderation, alcohol may be hard on your heart.
A new study finds having as little as 1 to 3 alcoholic drinks per day may increase your risk for atrial fibrillation, or A-fib.
Atrial fibrillation is the most common abnormal heart rhythm with symptoms ranging from lack of energy, to heart palpitations, to chest pain.
Karolinska Institute researchers, in Sweden, studied more than 79,000 adults age 45 to 83.
They followed them for 12 years and found an increased risk for atrial fibrillation with moderate drinking of wine and liquor.
Moderate drinking was defined as one to three alcoholic drinks per day.
the study also showed the more wine and liquor you drink, the bigger the risk for A-fib, but did not find such a relationship with beer.
Researchers say the adverse effects may be less pronounced if alcohol consumption is spread out over the week.
