AimsWe sought to investigate whether combining left ventricular (LV) volumes, regional wall motion abnormalities, and scar tissue extent obtained by cardiac magnetic resonance (CMR) improves risk stratification of patients with previous myocardial infarction (MI).Methods and resultsIn 231 consecutive patients (age 64 ± 11 years, males 89%) with previous MI, we quantified LV volumes and regional wall motion abnormalities by cine CMR, and measured the extent of the infarction scar by late gadolinium enhancement (LGE). During follow-up (median, 3.2 years) cardiac events (cardiac death or appropriate intra-cardiac defibrillator shocks) occurred in 19 patients. After adjustment for age, an extent of LGE >12.7%, an LV end-diastolic volume >105 mL/m(2), and a wall motion score index >1.7 were independent associated with adverse cardiac events at multivariate analysis (P < 0.05, P < 0.001, and P < 0.01, respectively). The patients with none of these factors, and those with one or two factors, showed a lower risk of cardiac events [hazard ratio (HR) = 0.112, P < 0.01 and HR = 0.261, P < 0.05] than those with three factors. The cumulative event-rate estimated at 4 years was 29.6% in patients with all three factors, 7.7% in those with one or two factors, and 3.5% in patients with none of these factors.ConclusionA multiparametric CMR approach, which includes the measure of scar tissue extent, LV end-diastolic volume and regional wall motion abnormalities, improves risk stratification of patients with previous MI.
