治疗急性心肌梗塞最有效的方法是使被阻塞的冠状动脉（冠脉）迅速再通。目前常用的方法是药物溶栓和冠脉成形术（PTCA）。我们采用脉冲染料激光冠脉内溶血栓术治疗3例，效果良好，报道如下。例1男，40岁。胸骨后压榨性痛4h入院。体检：BP12／8kPa，HR108次／min，余无异常。ECG The most effective way to treat acute myocardial infarction is to prompt recanalization of the blocked coronary artery (coronary artery).

Example 1 male, 40 years old. Sternal back pain 4h admission. Physical examination: BP12 / 8kPa, HR108 times / min, I no exception. ECG
