STI(心脏收缩时间间期)可反映心脏瞬间血流量的变化,对了解心脏的功能状态有重要意义。近年来,有关STI的测定在冠心病、心肌梗塞等心血管疾病方面屡有报道。但对支气管哮喘合并COPD(慢性阻塞性肺疾病)和肺心病患者的STI改变报道资料甚少。我们利用STI这种无创伤性的心功能检查法,对73例支气管哮喘合并COPD和肺心病患者进行了测定,现将结果报告如
STI (systolic time interval) can reflect changes in the instantaneous blood flow of the heart, to understand the functional status of the heart of great significance. In recent years, the determination of STI in coronary heart disease, myocardial infarction and other cardiovascular diseases have repeatedly been reported. However, little data have been reported on the changes of STI in bronchial asthma with COPD (chronic obstructive pulmonary disease) and pulmonary heart disease. We use STI this noninvasive cardiac function test, 73 cases of bronchial asthma combined with COPD and pulmonary heart disease were measured, the results reported
