作者观察睡眠呼吸暂停与缺血性心脏病的关系,并将非选择性急性心肌梗塞(MI)的男性幸存者与无缺血性心脏病的男性进行比较。病人和方法 101例年龄37～65(平均53.9)岁。因 MI 入院治疗后同意进行睡眠研究。除外严重精神或神经疾病、言语困难和严重心衰的病人,以及醒时动脉氧饱和度(SaO_2)小于90%的慢性肺疾病患者。研究是在 MI 发生后6～61(平均24)天于出院后在睡眠实验室内进行。从20点到6点进行多项睡眠图检查研究。利用热变电阻器测定口鼻气流、脉搏血氧定量计测定 SaO_2。呼吸暂停发作是指鼻或口气流缺乏至少持续10秒钟,呼吸浅慢是指气流减少持续10秒钟以上,并且 SaO_2至少下降4%。每小时睡眠的呼吸暂停发作数和呼吸暂停加呼吸浅慢数分别称为呼吸暂停指数(AI)和呼吸暂停/呼吸浅慢指数(AHI)。并测
The authors observed the relationship between sleep apnea and ischemic heart disease and compared male survivors of non-selective acute myocardial infarction (MI) with those without ischemic heart disease. 101 cases of patients and methods age 37 ~ 65 (average 53.9) years old. After MI admitted to hospital for treatment of sleep agreed. Patients with severe mental or neurological disorders, speech difficulties and severe heart failure, except for patients with chronic lung disease who have less than 90% arterial oxygen saturation (SaO_2) at wake. The study was performed in a sleep laboratory 6 to 61 (24 days on average) after MI. From 20:00 to 6:00 for a number of sleep map examination study. Nasal flow was measured with a thermistor, and pulsed oximetry was used to measure SaO_2. Apnea episodes are those in which the nose or mouth flow lacks for at least 10 seconds, slow breathing refers to a reduction in air flow lasting more than 10 seconds, and SaO 2 decreases by at least 4%. Hourly sleep apnea episodes and apnea plus shortness of breath are called apnea index (AI) and apnea / hypopnea index (AHI), respectively. And measured
