Snoring and risk of cardiovascular disease

Abstract In order to evaluate the possible role played by snoring as a risk factor for cardiovascular disease, we studied 400 patients aged 30–80 years, divided into 4 groups matched for age, sex and body mass index. The first group consisted of 100 patients who snored, having risk factors (hypertension, diabetes, obesity, smoking, high serum cholesterol level) for cardiovascular disease. The second group consisted of 100 non-snoring patients with risk factors. The third and fourth groups were formed by 100 snoring and 100 non-snoring patients without risk factors. We investigated the morbidity and the mortality from cardiovascular disease over a period of five years (1982–1987). An increase in morbidity and mortality was found for snorers with risk factors (36 and 17 respectively) compared to non-snorers with risk factors (10 and 4, P P P
