Abstract:
Objective To investigate the relationship between obstructive sleep apnea-hypopnea syndrome(OSAHS)and plasma homocysteine(Hcy)levels in patients with ischemie cerebrovascular disease(ICVD).Methods Seventy-six patients with ICVD were monitored with polysomnography(PSG) for 7-8 hours during sleeping.The levels of fibrinogen(FBG),high density lipoprotein cholesterol(HDLC),low-density lipoprotein cholesterol(LDL-C),triglyceride(TG)and plasma Hey were assessed.Results Of the 76 ICVD patients,57 showed apnea symptom during sleeping,of which 53(69.7%)were diagnosed with OSAHS and 4 with central sleep apnea,According to the mean apnea-hypopnea index (AHI),the severity of apnea was classified as no apnea symptom(19 cases with mean AHI of 2.38±0.96 and Hey level of(8.78 ±2.01)μmol/L),mild apnea(21 cages with mean AHI of 14.14 ±4.37 and Hcy level of(12.91 ±3.00)μmol/L),moderate apnea(24 cases with mean AHI of 29.62±5.81 and Hcy level of(14.85 ±4.15)μmol/L)and severe apnea(8 cases with mean AHI of 46.75±2.82 and Hcy level of(19.30±4.82)μmol/L).The level of Hcy was statistical significant among these 4 groups(F=40.32,P<0.01)and correlated with the mean AHI(r=0.598,P<0.01).Conclusion Patients with ICVD have a high morbidity of OSAHS,mainly suffering from mild to moderate apnea;The plasma Hcy level elevates in the ICVD patients with OSAHS and is correlated with the severity of apnea.
