Abstract

Background: Patients with acute pulmonary embolism (PE) have a high risk of death. N-Terminal pro-Brain Natriuretic Peptide (NT-pro BNP) has emerged as a biomarker for risk assessment in acute PE.

Objective: We aimed to detect in hospital prognostic value NT- pro BNP in patients with acute PE.

Methods: Sixty four patients  with  acute  PE .All patients  were subjected to ECG,  laboratory tests ( D-Dimer, troponin I,NT-pro BNP), Doppler  ultrasound for the venous system of lower limbs, echocardiography and 64 multislices CT pulmonary angiography.

Results: Patients were divided into two groups: group I (22) patients with normal NT-Pro BNP (<300 pg/ml), and group II (42) patients with elevated NT-Pro BNP. Group II had higher incidence of heart failure (28.6% vs. 4.6% P=0.025), impaired kidney function (creatinine 1.7 ±0.6 vs 1.1 ± 0.2 ,P=0.018) and cardiogenic shock (26.2% vs. 0% P=0.014) but lower incidence of chest pain (21.4% vs 45.5% P=0.04) and lower LV ejection fraction (51.3% ± 16.9% vs. 67.3% ± 12.8% P=0.043) compared to group I. Group II had higher treatment with thrombolytic therapy (35.7% vs. 9.1%, P= 0.021) and positive inotropic  (35.71% vs 4.55%, P=0.006) ,higher need for mechanical ventilation (26.2% vs. 4.55%, P=0.04) ,longer hospital stay (19.5 ±10.3 vs 5.3±4.5, p= 0.001) and higher mortality (19.05% vs. 0.0% P=0.042) than group I.

Conclusion: Elevated NT-pro BNP levels in patients with PE are associated with worse short term prognosis in terms higher of morbidity and mortality and it could be used as a valuable prognostic parameter and good indicator for the need of more aggressive therapy.
