title: Predictors of in-hospital mortality in patients receiving thrombolytic therapy for pulmonary embolism.
abstract: Predictors of in-hospital mortality from massive pulmonary embolism (PE) were retrospectively assessed in 78 patients who received thrombolytic therapy. Mortality from PE was 19% (15 of 78). Mortality from PE was higher in those with shock, 36% (12 of 33) versus no shock, 7% (3 of 45; P = .001), 21% (7 of 34) with right ventricle (RV) hypokinesis, and 20% (13 of 64) with RV enlargement. Mortality was 14% (2 of 14) with normal cardiac troponin I (cTnI), 19% (4 of 21) with intermediate cTnI, and 22% (8 of 36) with high cTnI (comparisons between groups nonsignificant [NS]). Trends with combinations of risk factors showed the highest mortality with shock plus high cTnI plus RV hypokinesis (57%) or shock plus high cTnI plus RV enlargement (54%). In conclusion, among the single risk factors, shock was associated with the highest in-hospital mortality from PE and combinations with high cTnI and RV enlargement were associated with higher mortalities.
