目前仍未明确人类慢性缺血性功能障碍心肌是随时间发生退行性变还是适应慢性缺血。作者研究未行血运重建的人类慢性顿抑心肌和冬眠心肌能否保存灌注、代谢以及收缩功能和储备。研究纳入16例无事件、射血分数为31%±2%、接受药物治疗的患者,这些患者经 It is still not clear that chronic myocardial ischemia in humans is degenerative or adaptive to chronic ischemia. The authors investigated whether intact, revascularized human chronic stunned myocardium and hibernating myocardium preserve perfusion, metabolism, and systolic function and reserve. Study included 16 patients without incident, ejection fraction was 31% ± 2%, receiving drug treatment of patients, these patients
