摘要 目的探讨OSAHS患者血清脂蛋白(a)和心肌肌钙蛋白I的变化及经鼻持续正压通气(nCPAP)对其影响。方法选择经多导睡眠图监测仪监测确诊的OSAHS 90例为实验组,根据呼吸暂停低通气指数(AHI)、最低血氧饱和度(SaO2min)将OSAHS分为轻度组50例,中度组26例,重度组14例,并设对照组40例。14例重度OSAHS患者接受nCPAP治疗为治疗组。用免疫透射比浊法(ITA)检测各组Lp(a)水平,用免疫化学发光法检测各组CTnI水平,比较各实验组与对照组、治疗组治疗前后的各项指标差异。结果①中、重度OSAHS患者Lp(a)水平显著下降(t=3.218,P值<0.01),重度OS-AHS患者nCPAP治疗前治疗后Lp(a)水平显著高于健康查体人群(t=3.117,P值<0.01);②中、重度OSAHS患者CTn-I水平显著高于健康查体人群(t=8.012,P值<0.01),重度OSAHS患者nCPAP治疗前比治疗后CTn-I水平显著下降(t=6.564,P<0.01)。结论OSAHS患者患动脉粥样硬化和血栓栓塞性心血管疾病的倾向显著增强,Lp(a)水平可作为OSAHS心血管功能病变的早期预测指标;中、重度OSAHS的心肌受到不同程度的损伤,cTnI水平可用为OSAHS心肌损伤的客观指标;nCPAP治疗可有效逆转上述病变。
