无并发症的急性心肌梗塞患者出院前进行亚极量活动平板试验常用于估计预后和指导治疗,但在梗塞后(≥6个月)康复期间进行极量运动试验估计预后的经验极少.限制心肌梗塞范围多中心研究组849例经确诊的心肌梗塞患者,至梗塞后6个月,已死亡130例,尚存活719例.其中473例(66%)按修订的Bruce方案进行活动平板试验,平均年龄54.8(20～75)岁,男性374例;包括穿壁性心肌梗塞298例,非穿壁性心肌梗塞133例,余42例体表心电图梗塞部位未定.另246例(34%)未进行运动试验,原因有:受心功能限制68例,非心脏性体力限制46例,不同意参加运动试验113例及其它原因19例.
Patients with uncomplicated acute myocardial infarction before discharge from the hospital are often used to assess prognosis and guide therapy, but very few exercise tests to estimate the prognosis during the recovery period after infarction (> 6 months) are rare. Myocardial Infarction A multicenter study of 849 patients with a confirmed myocardial infarction had 130 deaths and 719 surviving 6 months after infarction, of whom 473 (66%) were active treadmill trials under the revised Bruce regimen, The average age was 54.8 (range: 20-75 years), including 374 males, including 298 cases of transmyocardial infarction, 133 cases of non-transmyocardial infarction and 42 cases of undetectable electrocardiographic infarction (246%) Exercise test for the following reasons: 68 cases of heart function restrictions, non-cardiac physical limitations in 46 cases, do not agree to participate in exercise tests in 113 cases and 19 cases of other reasons.
