Descrição: Background Echocardiographic measurements of left ventricular (LV) function, predominantly LV ejection fraction (LVEF), have been used to define risk in patients after myocardial infarction. However, the extent to which measures of LV structure and function provide incremental prognostic value over clinical variables in survivors of high-risk myocardial infarction has not been well defined. Methods Predictors of death and development of heart failure were assessed in 603 patients from the Valsartan in Acute Myocardial Infarction (VALIANT) echocardiographic substudy. We used multivariable proportional hazards models to assess the individual predictive value of echocardiographic measures including left ventricular mass index, LVEF, LV volumes, left atrial volume index, right ventricular fractional area change, mitral regurgitation, and deceleration time. We adjusted for the 11 clinical variables found previously to be most associated with all-cause mortality in this cohort. Receiver operating characteristic curves obtained via binary response regression were used to assess the incremental predictive value of echocardiographic measures in predicting outcomes of death and hospital stay for heart failure. Results Each echocardiographic measure was independently associated with outcome of death or development of heart failure (all P < .002). Left ventricular ejection fraction alone added minimal prognostic value to the clinical assessment, yet adding additional echocardiographic assessments to a multivariable model improved in predicting 17-month survival free of heart failure significantly, increasing the c-statistic from 0.74 to 0.84 ( P < .001). Conclusion Echocardiographic measures of cardiac structure and function beyond LVEF provide important prognostic information beyond the clinical assessment.
