Smoking raises lifetime risk of irregular heart rate

Smoking and alcohol consumption increase lifetime risk of a rapid and irregular heart rate, called atrial fibrillation, which can lead to a stroke, dementia, heart failure and other complications, a new study says. The results, published in journal showed that that among individuals aged 55 years or older, the overall lifetime risk of atrial fibrillation (AF) was 37 per cent and was influenced by the burden of lifestyle risk factors such smoking and drinking alcohol. “We examined the lifetime risk of atrial fibrillation, which measures the cumulative risk of developing a disease during the remainder of an individual’s life,” said study co-author Ludovic Trinquart, Assistant Professor at Boston University School of Public Health in Massachusetts, US.
