Assessment of relationship between snoring and risk of coronary artery disease

Snoring is common in the general population, with up to 25% of women and 45% of men reporting habitual snoring. Obstructive sleep apnea (OSA) is frequent and affects 4% and 2% of middle-aged men and women respectively. In some study, Snoring is associated with a significantly increased risk for acute myocardial infarction and stroke in men and women. Epidemiologic studies in Caucasian populations have shown association of snoring and sleep apnea with vascular disease. We examined whether snoring was directly related to cardiovascular disease. This article was case-control study. All patients underwent cardiac vessel angiography in two catheter labs in Qom hospitals. 92 patients were normal or minimal stenosis (<50%) and another 92 patients were with 1, 2 or 3 vessels disease. Then Berlin questionnairewas completeed by and compare two groups and analyzed using and the P Value less than (‹0.05)was consideredstatistically significant. SPSS16 software. mean ageof patients was 55.83± 10.83,and 64.1% 118 (64.1%) patients were females. This study showed no significant difference between snoring with coronary artery disease (P=0.349). In the other hand, there are significant relationship between snoring and hypertension (P<0.001) and between risk factor of obstructive sleep apnea and coronary artery disease (P=0.008). However, we didnt show prominent relationship between snoring and diabetes mellitus also between snoring also hyperlipidemia (P=0.853, P=0.214 respectively) according to this study, in spite to correlation among risk factors of obstructive sleep apnea and coronary artery disease, simple snoring was not risk factor for development of cardiovascular disease.
