海报摘要
- Late revascularization following a myocardial infarction has questionable clinical benefit. We studied 13 patients with anterior wall myocardial infarction who underwent percutaneous coronary intervention within 2 weeks of the primary event, by quantitative analysis of 2-dimensional echocardiographic images. Endocardial segmentations of the left ventricular (LV) endocardium from the 4-chamber views were studied over time to establish cumulative wall displacements (CWDs) throughout the cardiac cycle. Results: Left ventricular end-systolic volume decreased to 42 ± 8 mL/body surface area (P = .034) and LV ejection fraction improved to 52% ± 7% (P = .04). Analysis of LV endocardial CWD demonstrated significant improvements in mid-systolic to late-systolic phases in the apical LV segments, from 3.5 ± 0.32 to 5.89 ± 0.43 mm (P = .019). Following late establishment of infarct-related artery patency , regional improvements were noted in the LV apical segments during systole and late diastole.
