Frequent hangovers and cardiovascular mortality in middle-aged men

Abstract

We studied the relation between frequent hangovers and cardiovascular mortality in a representative population sample of middle-aged Finnish men who participated in the Kuopio Ischemic Heart Disease Risk Factor Study. Complete data on alcohol consumption, hangover frequency, prior cardiovascular diseases, and risk factors were obtained for 2,160 non-abstinent men. Frequent hangovers were rare in the three lowest alcohol consumption quartiles, but in the highest quartile, a total of 239 men (43.6%) reported having a hangover at least monthly. During an average follow-up time of 6.7 years, these men had a 2.36-fold (95% confidence interval = 1.02-5.48) risk of cardiovascular death compared with men with fewer hangovers, with adjustment for age and total alcohol consumption. The association was somewhat attenuated after adjustments for smoking, income, and prior cardiovascular diseases. Systolic blood pressure, body mass index, resting heart rate, or serum lipids had no appreciable role in the relation, but plasma fibrinogen concentration appeared as one possible pathway to increased risk of cardiovascular death in men who frequently experience hangovers. The findings underline the importance of preventive actions regarding not only the amount but also the way people consume alcohol.
