目的 评价心肌造影超声心动图对急性心肌梗塞后再灌注的再通血流和侧支血流联合评估的意义。方法 35例连续积累的急性透壁性心肌梗塞患者,在经直接血管形成术成功恢复冠脉再灌注后即刻行心肌造影超声心动图检查。在冠脉成形术前评估侧支血流,再灌注15min后评估再通血流情况。
Objective To evaluate the significance of myocardial contrast echocardiography in the evaluation of recanalization and collateral flow after acute myocardial infarction. Methods Thirty-five consecutive patients with acute transmural myocardial infarction were examined by myocardial contrast echocardiography immediately after successful coronary revascularization by direct angioplasty. Collateral flow was assessed before coronary angioplasty and reperfusion was assessed 15 min after reperfusion.
