Anterior Wall Myocardial Infarction

Background: Late revascularization following a myocardial infarction has questionable clinical benefit. Methods: 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). Improvements in CWD were also observed in the late-diastolic phase of the cardiac cycle, from 1.50 ± 0.42 to 1.76 ± 0.52 mm ( P = .04). Conclusions: In our pilot patient cohort, following late establishment of infarct-related artery patency following an anterior wall myocardial infarction, regional improvements were noted in the LV apical segments during systole and late diastole.

Background: The effect of late percutaneous coronary intervention on left ventricular function is incompletely understood. Objectives: To evaluate the effect of late Percutaneous Coronary Intervention on LV systolic function following coronary stenting after acute anterior myocardial infarction. Methods: A total of 60 patients, > 24 hours to 6 weeks after anterior AMI who attended in UCC, BSMMU between July 2014 to June 2015 were included in this study. They underwent coronary stenting. After coronary stenting all patients were in TIMI flow-3. Serial echocardiographic assessment of LV function before and after late intervention with modified Simpson’s rule in apical 4 chamber view as well as comparison between baseline result with that of after intervention were done. The patients were on standard medical therapy in post intervention period. Result: Mean age was 54.3±8.91 years with minimum 30 years and maximum 75 years. Most of the patients were male (67%). LVESV was 60.0±14.4 ml before PCI and 58.3±15.3 ml at discharge (p value 0.091) & 44.1±17.6 ml after 3 months (p value <0.001). LVEF was 40.2±3.1% before PCI, 40.2±3.3% at discharge (p value 0.509) & 47.6±5.9% after 3 months (p value <0.001). There was no significant improvement of LV function from baseline till discharge but significant improvement occurred after 3months. Conclusion: Using echocardiographic techniques, our results showed that left ventricular volume decreased and the left ventricular ejection fraction increased significantly after three months of late intervention.
