ABSTRACT
ObjectiveTo explore the value of combined echocardiography and brain natriuretic peptide (BNP) levels in acute pulmonary embolism (APE) treated by thrombolysis.Methods Echocardiography,pulmonary ventilation-perfusion imaging and plasma BNP levels were performed before thrombolysis and 24 - 48 h after thrombolysis in 31 patients with diagnosis of APE and signs of right ventricular pressure overload.Results Twenty-six patients with thrombolysis effective,after thrombolysis,the pulmonary artery systolic pressure decreased from (57.3 ± 18.2)mm Hg to (40.4 ± 15.4)mm Hg (P= 0.003) ,the right ventricular diastolic diameter reduced from (40.6 ± 6.1)mm to (35.4 ± 6.0)mm (P ＜0.01) ,the pulmonary artery diameter reduced from (27.2 ± 4.9)mm to (22.5 ± 4.4)mm (P = 0.004) ,the left ventricular diastolic diameter increased from (42.4 ± 7.2)mm to (43.1 ± 6.9)mm (P = 0.42),septal contradiction were reduced from 20 cases to 10 cases (P = 0.02),plasma BNP levels decreased from (278.8 ± 43.3)ng/L to (119.1 ± 40.4)ng/L (P = 0.000 01).Five patients with thrombolysis ineffective,there were no significant changes before and after thrombolytic therapy in the parameters of echocardiography,however,plasma BNP levels increased from (431.8 ± 57.7) ng/L to (496.4 ± 70.3) ng/L(P = 0.03).Plasma BNP levels and pulmonary artery systolic pressure had a better relationship(r = 0.62,P ＜0.01).Conclusions The pulmonary perfusion and right ventricular function in patients with APE can be rapidly improved by thrombolytic therapy.Combined echocardiography and the BNP levels is a sensitive index in the hemodynamic changes of thrombolytic therapy,and can evaluate the treatment accurately.
ABSTRACT
AIM: To investigate the effect of Ginkgo Biloba Extract on coronary blood flow in patients with coronary artery disease(CAD). METHODS: Ninety CAD patients confirmed by cardioangiography were randomly assigned to Ginkgo Biloba Extract Injection group(n=45) and control groups(n=45).Before and after intravenous administration,the distal left anterior descending coronary artery(LAD) flow was measured by transthoracic Doppler echocardiography. RESULTS: Ginkgo Biloba Extract Injection treatment demonstrated significant improvement in diastolic peak velocity,systolic peak velocity and diastolic time velocity integral(P0.05). CONCLUSION: CAD patients in the treatment of Ginkgo Biloa Extract lead to the increase in LAD blood flow.
