Researchers at Sweden’s Karolinska Institute in Stockholm found that women who had already suffered a heart attack or had heart surgery for blocked arteries had higher Heart Rate Variability (HRV) if they drank moderately than if they drank nothing at all.
HRV measures the intervals between heartbeats, with lower rates being associated with higher risks of heart disease and death.
Researchers do warn against binge drinking though, pointing out that it only limited regular intake is beneficial.
More importantly the results were strongly seen with wine, with little effect from beer or spirits.
The results of the study have been published in the British Medical Association’s specialist journal Heart.
