Clinical Significance of Late Diastolic Tissue Doppler Velocity at 24 Hours or 14 Days After Onset of ST-Elevation Acute Myocardial Infarction.

ABSTRACT: Background: The significance of late diastolic velocity (a') obtained by tissue Doppler imaging (TDI), which reveals atrial function, in ST-elevation myocardial infarction (STEMI) remains unclear. This study evaluated the association of TDI parameters determined either immediately or 2 weeks after percutaneous coronary intervention (PCI) with long-term outcomes. Methods and Results: In all, 740 patients with first-time STEMI underwent immediate PCI (i.e., within 12 h of onset). Echocardiography was performed in 307 patients 2 weeks after onset (Group A; mean age 64 years, 249 males), in 277 patients immediately after PCI (Group B; mean age 65 years, 229 males), and in 156 patients twice (i.e., immediately and 2 weeks after PCI; Group C; mean age 65 years, 135 ma
