急性心肌梗死后数小时至30天内出现的反复心绞痛,定义为梗死后心绞痛,可发生于休息或轻微体力活动时,发生率23％至60％。“梗死后心肌缺血”可在无心绞痛时发生。无痛性ST—T改变,伴或不伴二尖瓣返流的反复发作的肺水肿及室性心律失常均说明有反复发生的梗死后心肌缺血,Q波及非Q波型心肌梗死及接受溶栓治疗者可发生梗死后心绞痛,而非Q波型梗死其梗死后心肌缺血的发生率较高。如果梗死后立即出现心绞痛,说明远离梗死区 Recurrent angina pectoris occurring within hours to 30 days after acute myocardial infarction, defined as post-infarction angina, occurs at rates ranging from 23% to 60% at resting or light physical activity. “Myocardial ischemia after infarction” can happen without angina. Painless ST-T changes, recurrent pulmonary edema with or without mitral regurgitation, and ventricular arrhythmias all indicate recurrent postischemic myocardial ischemia, Q-wave non-Q-wave MI and acceptance Thrombolytic therapy can occur after angina pectoris, rather than Q-wave infarction infarction myocardial infarction after a higher incidence of ischemia. Angina pectoris occurs immediately after infarction, indicating that it is far from the infarct zone
