[Obstructive sleep apnea and a cardiovascular risk in patients with arterial hypertension].
To study an independent role of the obstructive sleep apnea syndrome (OSAS) in patients with arterial hypertension (AH) according to the data of a retrospective observation. ⋯ Among 120 enrolled patients, 64 (53%) had OSAS. In the patients with OSAS, the baseline AHI was 50.9 +/- 23 events per hour whereas in the control group it was 8.9 +/- 5.2 per hours. Both groups were comparable in age, height, weight, body mass index, snore duration, drowsiness, and respiratory standstill during sleep, blood pressure, total cholesterol, and creatine. While analyzing OSAS, there was no change in the risk for a combined end point (all-cause death, stroke, myocardial infarction, chronic heart failure, atrial fibrillation, or intermittent claudication). Our study was retrospective, the patients were few and AH is itself an important cardiovascular risk factor which should be borne in interpreting the results of our study. We consider that the study of the independent role of OSAS should be continued within a well-designed prospective observation.
