Meimoun P, Abdani S, Stracchi V, et al. - Researchers investigated the utility of noninvasive myocardial work (MW), a new index of global and regional myocardial performance, to prognosticate left ventricular recovery (LVR) and in-hospital complications after ST-elevation myocardial infarction (STEMI). A total of 93 patients with anterior STEMI (mean age, 59 ± 12 years) treated by the percutaneous coronary intervention (PCI) were included prospectively; a transthoracic Doppler echocardiography was performed within 24-48 hours after PCI and a median of 92 days at follow-up. This study characterized in-hospital complications as a composite of death, reinfarction, heart failure, and LV apical thrombus. The data exhibited that constructive MW is an independent predictor of segmental and global LVR in patients with anterior STEMI treated by PCI, and is significantly impaired in patients with in-hospital complications.
