Kaplan–Meier curves comparing survival probability after myocardial infarction in female rats according to Doppler echocardiogram predictors of mortality. Survival estimates in the≥37% infarction digitoxin and placebo groups: A) FAC: fractional area change; B) E\A ratio; C) LVDD: left ventricle diastolic diameter; D) LVSD: left ventricle systolic diameter; E) LVSA: left ventricle systolic area. *P<0.05 (log rank test).
