本文研究冠状动脉疾病患者在起搏或运动诱发心绞痛时硝苯吡啶的即刻血流动力学效应,并估计药物对急性心肌梗塞后静息时左心室功能中度低下患者的效果.方法:第一研究组包括8例考虑作旁路手术的男性无并发症稳定型心绞痛患者,平均年龄52岁.平板运动试验时出现典型心绞痛及ST段至少压低1毫米.左室造影喷血分数大于50%,左室舒张末期压平均9毫米汞柱.冠状动脉造影有三支血管病变者4人,二支者3人,一支者1人.试验当天,在插入导管后先作4分钟的准备运动,15分钟后按规
This article studies the immediate hemodynamic effects of nifedipine in patients with coronary artery disease during pacing or exercise-induced angina and estimates the effect of the drug on patients with moderately depressed left ventricular function at rest following acute myocardial infarction.Methods: The study group included 8 patients with stable angina without complications who were considered as bypass surgery, with a mean age of 52. Patients with typical angina pectoris and ST-segment depression at least 1 mm were excluded from the treadmill exercise test.Left ventricular ejection fraction was greater than 50% Left ventricular end-diastolic pressure average 9 mm Hg coronary angiography with three vascular lesions in 4 people, two in three, one in 1. On the day of the test, after the introduction of the catheter for 4 minutes after the first exercise, 15 Follow the rules in minutes
