SUMMARY
Systematic reviews and meta-analyses have suggested that RV dysfunction on echocardiography is associated with an elevated risk of short-term mortality in patients who appear hemodynamically stable at presentation (non-massive pulmonary embolism), but its overall positive predictive value for PE-related death was low (III (P = 0.003).
In the current study, there was a significant statistical difference between the 2 groups as regarding use of LMWH (p value=0.015)
In the current study, mean right ventricular free wall strain was significantly reduced in patients of group I compared with group II patients (P < 0.001).
In the current study, mean right ventricular global wall strain was significantly reduced in patients of group I compared with group II patients (P < 0.001).
In the current study, mean FAC was significantly lower in patients of group I compared with group II patients (P < 0.001)
In the current study, mean TAPSE was significantly lower in patients of group I compared with group II patients (P=0.003).
In the current study, mean S velocity was significantly lower in patients of group I compared with group II patients (P= 0.001).
According to multivariate logistic regression analysis, predictors for in-hospital event were RV free wall strain (P=0.006), RV global wall strain (P=0.008), FAC (P=0.012) and S velocity (P=0.012).
FAC showed significant positive correlation with RV free wall strain (P= 0.002) & with RV global strain (P = 0.001).
TAPSE showed significant positive correlation with RV free wall strain (P= 0.006) & with RV global strain (P= 0.017).

RIMP showed significant negative correlation with RV free wall strain (P= 0.024) & with RV global strain (P= 0.013)
RV free wall strain showed significant AUC of 0.964. Best cutoff was ≤-14.6 at which sensitivity and specificity were 100% and 87.4% respectively. P value was
