作者曾对核素心脏血池显像中的多个心功能参数进行了分析,认为运动试验时心率×血压的乘积(HR.BP)搏mmHg/分及LVEF(左室射血分数)对冠心病冠状动脉狭窄的数目判断有较大意义。本文通过对622例冠脉造影证实的冠心病患者进行运动试验的核素血池显像,进一步了解HR.BP及LVEF与冠状动脉狭窄数目的关系。方法:622例冠状动脉造影证实的冠心病患者均无心肌梗塞病史,也无其它心脏疾患及心脏手术史。患者中46%者长期服用β-受体阻滞剂。脚踏车运动试验的负荷逐渐加重至规定终止标准。同时记录心
The authors have analyzed multiple cardiac function parameters in radionuclide blood pool imaging and concluded that the HRBP (mmHg / min) and LVEF (left ventricular ejection fraction) Coronary artery stenosis coronary heart disease to determine the number of great significance. In this paper, 622 cases of coronary heart disease confirmed by coronary angiography in patients with exercise test nuclide blood pool imaging to further understand the relationship between HR.BP and LVEF and the number of coronary artery stenosis. Methods: Sixty-two patients with coronary heart disease confirmed by coronary angiography had no history of myocardial infarction and no other heart disease and history of cardiac surgery. Forty-six percent of patients long-term use of beta-blockers. The load on the bicycle exercise test gradually aggravates to the prescribed termination standard. At the same time record the heart
