作者通过回顾性随访研究,探讨经运动放射性核素心血管造影确诊的无痛性心肌缺血患者的远期预后及不同治疗对心肌缺血预后的影响。1982年1月至1983年12月间经运动放射性核素(~(99m)锝门血池)造影确诊心肌缺血152例,缺血定义为运动后喷血分数减低≥10％,或喷血分数减低≥15％伴明显室壁活动异常。资料完整者140例列入研究,按运动试验中有无心绞痛症状分成两组:症状组56例,无痛性心肌缺血组84例(60％),两组年龄、运动负荷和心肌缺血部位均无显著差异。平均随访52(6～69)个月,严重心脏
The retrospective follow-up study by the authors to explore the long-term prognosis of patients with painless myocardial ischemia diagnosed by exercise radionuclide cardiovascular angiography and the impact of different treatment on myocardial ischemia prognosis. Between January 1982 and December 1983, 152 cases of myocardial ischemia were diagnosed by exercise radionuclide (~ (99m) T cell portal), and ischemia was defined as a decrease of ≥10% in spurting scores after exercise or spurting Score reduced ≥ 15% with obvious abnormal wall activity. Complete data were included in the study of 140 cases, according to exercise test whether the symptoms of angina divided into two groups: 56 cases of symptoms, painless myocardial ischemia in 84 cases (60%), two groups of age, exercise load and myocardial ischemia No significant difference in site. The average follow-up of 52 (6 to 69) months, severe heart
