Echocardiographic predictors of early in-hospital heart failure during first ST-elevation acute myocardial infarction: does myocardial performance index and left atrial volume improve diagnosis over conventional parameters of left ventricular function?

Table 3 Cut-off values of echocardiographic continuous variables with statistical significance with respective diagnostic indexes and area under curves

Variable	Cut-off	S (%)	E (%)	PPV (%)	NPV (%)	Area under curves ROC
LVEF	0.45	87.9	62.1	84.0	69.2	0.77
WMSI	1.8	65.5	75.8	54.3	83.3	0.77
MPI	0.57	79.3	54.6	43.4	85.7	0.67

Legend: S: sensitivity; E: specificity; PPV: positive predictive value; NPV: negative predictive value; ROC: receiver operator characteristics; LVEF: left ventricular ejection fraction; WMSI: wall motion score index; MPI: myocardial performance index.
