Abstract

To evaluate by cardiovascular magnetic resonance those factors related to the amount of salvaged myocardium after a myocardial infarction and its value in predicting adverse ventricular remodeling. One hundred eighteen patients admitted for a first ST elevation myocardial infarction (primary angioplasty, 65 patients; a pharmacoinvasive strategy, 53 patients) underwent magnetic resonance (6 [5-8] days and 6 months; n=83). The myocardial salvage index was quantitatively assessed as the percentage of area at risk (T2-weighted sequences) not showing late enhancement. Myocardial salvage index >31% (median) was associated with a shorter time to reperfusion (153 min vs 258 min), a lower rate of diabetes (12% vs 32%), shorter time to magnetic resonance, and better cardiovascular parameters (P<.05 for all analyses). There were no significant differences depending on the reperfusion method. In a logistic regression analysis, delayed reperfusion (odds ratio=0.42 [0.29-0.63]; P<.0001), diabetes (odds ratio=0.32 [0.11-0.99]; P<.05) and a longer time to the performance of magnetic resonance (odds ratio=0.86 [0.76-0.97]; P<.05) were independently related to a lower probability of a myocardial salvage index >31%. Predictors of increased left v...Continue Reading

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.
