3-4 Predictors of successful intervention
In those who had successful response to thrombolytic therapy, median (IQR) elapsed time from surgery was significantly less than those with partial or ineffective responses (p = 0.02), demonstrated in(Fig. 1) . With respect to admission INR and the average INR of prior 3-6 months, it was observed that patients with successful response had lower mean of admission INR than those with unsuccessful response (2.37 ± 1.23 vs. 2.98 ± 1.16), while the latter group with unsuccessful response had lower average INR in prior 3-6 months (2.41 ± 0.36, p = 0.004). Although there was no statistically significant association between functional class and response to therapy, those who had successful response had less extremity edema (23.5%) and less increased jugular venous pressure (5.9%, p = 0.012).
