【摘要】 目的:監测住院冠心病患者中睡眠呼吸暂停(sleep apnea,SA)的发生情况及对心功能的影响。方法:对笔者所在医院2012年1月-2016年
6月132例经冠状动脉CT或造影证实的冠心病患者进行整夜多导睡眠监测,根据结果分为冠心病合并睡眠呼吸暂停组(31例)、冠心病不合并睡眠呼吸暂停组(101例)。通过血氧测定、心脏超声等监测其对心功能的影响。结果:23%的冠心病患者并发SA,冠心病合并SA组患者的体重指数显著高于冠心病不合并SA组患者,差异有统计学意义(P<0.05);两组间其他危险因素比较,差异无统计学意义(P>0.05);冠心病合并SA组的最低血氧饱和度(LsSaO2)、左室射血分数(LVEF)较冠心病不合并SA组低,左室舒张末期内径(LEVDD)较冠心病不合并SA组大,差异均有统计学意义(P<0.05)。结论:冠心病患者中SA的发生率较高,睡眠呼吸暂停可影响血氧饱和度,加重低氧血症,并使心功能恶化。对冠心病的认识需重视伴发的睡眠呼吸暂停,为制定冠心病患者的二级预防策略及改善预后提供新思路。

【Abstract】 Objective:To monitor the prevalence of sleep apnea with coronary heart disease and its effect on cardiac function.Method:All night polysomnography was performed in 132 patients with coronary heart disease(CHD) confirmed by coronary CT or angiography in our hospital from January 2012 to June 2016,according to the points to coronary heart disease with sleep apnea(SA) group(31 cases),coronary heart disease without SA group(101 cases).The effect of the blood oxygen and heart ultrasound on the cardiac function were monitored.Result:23% of patients with coronary heart disease complicated with SA,SA in patients with coronary heart disease(CHD) body mass index was significantly higher than that of CHD without SA patients,the difference was statistically significant(P<0.05).There were no statistically significant differences between the two groups among other risk factors(P>0.05);the lowest oxygen saturation(LsSaO2) and left ventricular ejection fraction(LVEF) in the SA group were lower than those in the without SA group,and the left ventricular end diastolic diameter(LEVDD) was increased,and the differences were statistically significant(P<0.05).Conclusion:In patients with coronary heart disease,the incidence of SA is higher,the sleep apnea can affect the blood oxygen saturation,increase the oxygen level,and make the heart function worse.The recognition of coronary heart disease should pay more attention to the sleep apnea,and provide a new idea for the development of two levels of prevention strategies and improve prognosis of patients with coronary heart disease.

睡眠呼吸暫停(sleep apnea,SA)是指睡眠过程中反复的呼吸停止或低通气,造成反复低氧和/或觉醒,引起一系列病理生理改变的综合征,SA分为阻塞型睡眠呼吸暂停(OSA)和中枢型睡眠呼吸暂停(CSA)[1]。近年来逐渐认识到SA是一种全身性疾病,因为它不仅可以引起缺氧、二氧化碳潴留,还会引起或加重高血压、冠心病、心律失常、心力衰竭、糖尿病及胰岛素抵抗、脑卒中,因而引起了许多学科医生的广泛关注。本研究的目的旨在探讨冠心病患者中SA的发生情况,以及对心功能的影响。
