We hypothesized that the presence of microvascular integrity, detected by myocardial contrast echocardiography (MCE) in dobutamine nonresponsive segments, may enhance identification of recovery of function, which is a surrogate marker of myocardial viability. Accordingly, 96 patients underwent dobutamine echocardiography (DE) and intravenous MCE on the same day, 4.6 ± 1.5 days after acute myocardial infarction (AMI). Recovery of function of akinetic segments was assessed at 3 months after AMI. Of 387 akinetic segments, 102 (26%) recovered function during follow-up. Sensitivities and specificities of MCE, DE, and the combination of DE and MCE in dobutamine nonresponsive segments were 58%, 59%, and 79%, respectively (p <0.001, compared with MCE and DE) and 76%, 84%, and 69%, respectively (p <0.05 compared with DE) for predicting recovery of function. In anterior AMI, the positive and negative predictive values of MCE, DE, and the combination of DE and MCE were 47% and 88%, 57% and 89%, and 49% and 95%, respectively. Multivariate analysis using clinical characteristics, electrocardiography, biochemical factors, MCE, and DE showed that the combination of DE and MCE in dobutamine nonresponsive segments (p <0.00001) and Q-wave AMI (p = 0.002) were the only independent predictors of recovery of function. Thus, for optimum prediction of recovery of function after AMI, a combination of DE and MCE in dobutamine nonresponsive segments may be utilized.
