本文指在判断大剂量长效硝酸酯与β阻滞剂加上硝苯吡啶是否能进一步改善症状而无明显副作用,以及硝苯吡啶对静息与运动时左室球泵功能的调节作用。方法:16例(男14,女2)病人虽用长效硝酸酯与β阻滞剂治疗,每周心绞痛发作仍≥3次,平均年龄59(43～70)岁。在静息与运动时作99m锝在核素心室造影,测定球泵射血分数(EF)。
This article refers to determine whether large doses of long-acting nitric acid esters and β-blocker plus nifedipine can further improve the symptoms without obvious side effects, and nifedipine on resting and exercising the regulation of left ventricular pump function. Methods: Sixteen patients (male 14 and female 2) were treated with long-acting nitric acid and β blockers. The weekly angina attack was still ≥3 times, with an average age of 59 (43-70) years. 99m technetium was radionuclide ventriculography at rest and exercise, and the ball pump ejection fraction (EF) was measured.
