经过十余年争论之后,血栓乃是急性穿壁性心肌梗塞之直接原因,已为冠脉内血栓溶解疗法、冠脉旁路手术和冠脉造影所确证。目前多数研究者认为70～80％穿壁性急性心肌梗塞为血栓形成所致。虽然有的作者认为非穿壁性急性心肌梗塞(心内膜下心肌梗塞)并非冠脉内血栓形成所致,而常常是急性心肌灌注不足并严重心律失常、低血压和冠状动脉痉挛的后果。但最近的研究指出,在非穿壁性急性 After more than ten years of debate, thrombosis is the direct cause of acute transmural myocardial infarction and has been confirmed by intracoronary thrombolysis, coronary artery bypass grafting and coronary angiography. At present, most researchers believe that 70 to 80% of transmural acute myocardial infarction caused by thrombosis. Although some authors believe that non-transmural acute myocardial infarction (subendocardial myocardial infarction) is not caused by intra-coronary thrombosis, it is often the consequence of acute myocardial perfusion deficits and severe arrhythmias, hypotension and coronary artery spasm. However, recent studies indicate that acute non-transmural
