Study of the Obstructive Sleep Apnea in the Patients with Cardiovascular Risk

摘要

Background Obstructive Sleep Apnea syndrome (OSA) is the syndrome of stopping the breath when sleeping. It is estimated that more than one quarter of the population is at risk for OSA, with increased prevalence noted in populations with hypertension, coronary artery disease, stroke, and atrial fibrillation. In Viet Nam, there are still a few studies of OSA. Objective To evaluate the prevalence of cardiovascular risk in OSA patients. Also, the correlation between AHI and BMI, SBP, DBP, blood glucose, Cholesterol, Triglyceride, LDL-C, HDL-C. Methods Clinical data of 30 OSA patients admitted to hospital were analyzed and compared to 30 healthy persons, without cardiovascular risk. We evaluated the incidence of cardiovascular risk in the OSA patients. We also find the correlations between AHI and age, BMI, systolic blood pressure, diastolic blood pressure, fasting glucose, Cholesterol, Triglyceride, LDL-C, HDL-C. Results 1. The prevalence of cardiovascular risk in the OSA patients: hyperlipidemia was 27.59%, hypertension was 18.97%, obesity was 20.69%, smoking was 13.79%, sedentary lifestyle was 8.62%, diabetes mellitus was 10.34%. 2. AHI correlated with SBS (r = 0.37, p < 0.05), Cholesterol (r = 0.32, p < 0.05) and BMI (r = 0.41, p< 0.05). Conclusions Basing on the correlation, cardiovascular risk should be concerned in OSA.
