Conference paper


Several diagnoses are possible for patients with unspecified precardiac pain. Since many of these patients have multiple risk factors for coronary heart disease (CHD), they undergo cardiological diagnostic procedures, often including heart catheterization. Frequently, the angiocardiographic findings in these patients do not explain their complaints. The correlation between nocturnal sleep disorders and cardiac risk factors has been reported in the recent international literature. Patients with sleep apnea syndrome and initially suspected but angiocardiographically excluded coronary macroangiopathy often suffer from very similar symptoms. We were therefore interested in the prevalence of a pathological sleep apnea activity in patients without angiocardiographic evidence of CHD. During a period of 14 weeks in 1988 we saw 32 male patients fulfilling the criterion mentioned above and aged between 35 and 65 years. Twenty-nine of these patients were examined for pathological sleep apnea activity. A sleep apnea diagnostic study was performed by means of the ambulatory recording unit developed by our working group. Ten out of 29 patients investigated showed a pathological apnea index ( ≥ 10 apneas/h sleep) whereas 10 further patients had a borderline apnea index between 5 and 9 apneas/h. Looking at risk factors for CHD we found hyperlipidemia in 19 patients, arterial hypertension in 17, obesity in 12, nicotinism in 11, hyperuricemia in 6 and diabetes mellitus in 1 patient.
