Background: Pulmonary emboli (PE) is a life threatening condition that discovered in many patients only "post mortem". Sub massive and massive PE that led to hemodynamic collapse characterized by right ventricular (RV) dysfunction, leading to a higher risk of death. Objectives: To assess the ability to predict in hospital death of patients with acute PE, using a non-gated computed tomography pulmonary angiography (CTPA), based on the dimensions of the right ventricle. Methods: A retrospective study that analyzed CTPA images of patients admitted with acute PE during the years 2012–2017. The cohort study included 300 patients with documented acute PE, among them 255 hospitalized in medical (non-intensive care unit) wards, 45 were hospitalized in an intensive care unit (ICU). Results: Among the 45 patients admitted to the ICU 8% died. Larger RV diameters predicted mortality (OR = 10.14, 95% CI [1.09–93.86]) as well as lower systolic and diastolic blood pressure measurements (p = 0.001 and 0.01). Among the 255 patients admitted to the Internal Medicine Ward 7% died. Older age (p = 0.028), sepsis and cancer (both p < 0.001), high WBCs count (p < 0.001), and renal failure (p < 0.001) predicted death. Lower blood pressure (systolic and diastolic) (p < 0.001, 0.008), older age (p < 0.007), sepsis (p < 0.001), cancer (p = 0.006), higher WBCs count (p < 0.001), and impaired renal function (p < 0.001) predicted death in patients admitted with acute PE. Conclusions: Clinical parameters and hematological parameters could predict death of patients admitted with acute PE. RV diameter, measured by the non-ECG gated CTPA, had an additive predictive value for patients who admitted to the ICU.
