| 目的 探讨小剂量多巴酚丁胺负荷超声(LDDSE)早期识别存活心肌和预测其功能恢复的临床价值。方法 28例急性心肌梗死患者,其中行直接PTCA术18例,入院后第10天进行LDDSE。结果 ①LDDSE检测存活心肌的敏感性、特异性、阳性预测值和阴性预测值分别为93.8%、61.9%、88.2%、76.5%。② 再灌注＜12h(11例)和＞12h(7例)的两组患者三个月时运动恢复的心肌节段分别为85.4%、62.2%,而未行PTCA组(10例)仅为9.1%。结论 LDDSE对急性心肌梗死患者心肌的存活性和功能恢复有较高的预测价值。 |

| Objective To evaluate the accuracy of assessing viability and functional recovery of the myocardium in acute myocardial infarction (AMI) with low-dose dobutamine stress echocardiography (LDDSE).Methods Twenty-eight patients with AMI were studied. Among them 18 cases were successfully treated with primary coronary angioplasty (TIMI Ⅱ-Ⅲ). LDDSE were performed at 10 days after hospitalization. Results ① The sensitivity, specificity, positive predictive value and negative predictive value of LDDSE in assessing the viable myocardium were 93.8%,61.9%,88.2% and 76.5%. ②The ratio of three month recovery of regional wall motion in reperfusion ＜12h (11 cases) and ＞12h (7 cases) after AMI were 85.4%, 62.2%, respectively. However, there was only 9.1% wall motion recovery in 10 cases without underwent coronary angioplasty. Conclusion LDDSE can accurately predict the recovery of dysfunctional but viable myocardium in patients with AMI. |
