According to a new study, consuming alcohol frequently increases the risk of stroke mortality in men. The study showed that people who drink alcohol more regularly than twice a week have over a threefold risk of stroke mortality than people who do not consume alcohol at all. Researchers at the University of Eastern Finland said that the effects of alcohol are not limited to the amount consumed, but the frequency of drinking also matters. The relationship between alcohol consumption and ischaemic stroke shows a J curve pattern, which means that in people who are moderate consumers of alcohol, the risk of stroke is the lowest, while heavy consumption of alcohol increases the risk of stroke, researchers said. The risk of cerebral haemorrhage increases linearly as the consumption of alcohol increases: the higher the amount of alcohol consumed, the higher the risk of stroke.
In addition to alcohol, other significant risk factors for stroke include elevated blood pressure, coronary artery disease, heart failure, atrial fibrillation, diabetes, smoking, overweight, asymptomatic carotid artery stenosis, and elevated cholesterol levels. The study was based on follow-up data from the Kuopio Ischaemic Heart Disease Risk Factor Study. At the onset of the study, the men participating in the study were middle-aged, and the follow-up time was 20 years. A total of 2,609 men participated in the study. The results were published in the journal Acta Neurologica Scandinavica.
