Snoring as a Risk Factor for Ischaemic Heart Disease and Stroke in Men
Heavy snoring, which is practically always present in obstructive sleep apnoea, seems to correlate with arterial hypertension [1-6]. During sleep, apnoeic patients may develop hypoxaemia and hypercapnia in association with a rise in pulmonary and systemic arterial pressure, and there may be increased susceptibility to cardiac arrhythmias [7-11]. Cardiac index decreases during an apnoeic episode and increases significantly on resumption of ventilation . There is increasing evidence for a correlation of snoring with cardiovascular disease. Cross-sectional surveys have indicated an association with ischaemic heart disease (IHD)  and with angina pectoris . A case-control study  of stroke patients found a relative risk (RR) of 2.8 for snoring, and 10.8 for habitual snoring. Prospective studies of snoring in relation to cardiovascular disease have not been reported.
