摘要
目的探讨合并存在OSAHS的冠心病患者外周血TNF-α、IL-6和高敏C-反应蛋白(hs-CRP)的水平,以及持续气道正压通气(CPAP)治疗后其水平的变化。方法选择2007年10月至2008年10月间在武汉大学人民医院心血管内科住院的冠心病患者76例,23例体检正常者作为正常对照。对冠心病患者进行多导睡眠监测(PSG),并检测76例冠心病患者及23例对照组外周血TNF-α、IL-6、hs-CRP水平。对中重度(AHI≥15次/h)OSAHS冠心病患者使用Auto-CPAP治疗3个月,治疗结束后,再次检测上述指标。结果76例冠心病患者中,41例(53.9%)合并中重度OSAHS(AHI≥15次/h),该组患者接受Auto-CPAP治疗。冠心病组TNF-α、IL-6、hs-CRP水平明显高于对照组(P均<0.01);中重度OSAHS冠心病患者TNF-α、IL-6、hs-CRP的表达均显著高于不合并OSAHS的冠心病患者,而在Auto-CPAP治疗后明显下降。结论冠心病患者存在明显的前炎症状态,OSAHS可能加剧冠心病的炎性损伤。对于存在中重度OSAHS的冠心病患者采用CPAP治疗可降低血清炎症因子水平。
Objective To investigate the changes and significance of serum inflammatory factors in coronary heart disease （CHD） patients with obstructive sleep apnea-hypopnea syndrome （OSAHS） , and the treatment effects of continuous positive airway pressure （CPAP）. Methods A total of 76 CHD patients in Renmin Hospital of Wuhan University from October 2007 to October 2008 were enrolled. Polysomnography （PSG） was performed in these CHD patients to identify if they were complicated by OSAHS. The levels of inflammatory factors including TNF-α, IL-6, high sensitive C-reactive protein （hs-CRP） in serum were determined in the CHD patients and 23 normal subjects. The CHD patients with moderate-severe OSAHS （AHI ≥15 episodes/hour） were treated by Auto-CPAP for 3 months and all parameters above were measured again. Results There were 41/76 （53.9%） of CHD patients had moderate-severe OSAHS and were treated with CPAP. The levels of TNF-α,IL-6 and hs-CRP were significantly higher in the CHD patients than those in the normal controls （ all P 〈0. 01 ） ,and were significantly higher in moderate-severe OSAHS patients than those in the non-OSAHS CHD patients. Auto-CPAP ventilation significantly decreased the levels of inflammatory factors in the CHD patients with moderate-severe OSAHS. Conclusions An obvious proinflammatory state is detected in CHD patients, and is aggravated with OSAHS. CPAP is a useful treatment for CHD patients with mediate to severe OSAHS.
