Abstract

Recent data suggest that brain natriuretic peptide (BNP) and troponin I (TnII) are useful markers of right ventricular dysfunction (RVD) and initial myocardial injury in acute pulmonary embolism. The aim of this study was to evaluate biohumoral activation and right ventricular function in patients with acute pulmonary embolism diagnosed at pulmonary scintigraphy. We observed 12 patients with massive pulmonary embolism (MPE), 8 with non-massive pulmonary embolism (NMPE) and RVD, 6 with NMPE without RVD. All the patients with MPE and 5 patients with NMPE-RVD received thrombolytic therapy (urokinase or recombinant tissue-type plasminogen activator), the others were treated with heparin. At the beginning and after pharmacological treatment all the 26 patients underwent standard echocardiography and blood test analysis. BNP and Tn1 were significantly high in MPE (BNP p < 0.001 and Tn1I p < 0.005 vs NMPE) and in NMPE-RVD (BNP p < 0.03 and Tnl p < 0.02 vs NMPE). MPE and NMPE-RVD had similar RVD (p = NS), thrombolysis significantly reduced BNP, TnI, systolic pulmonary pressure, both in MPE (p < 0.001) and in NMNPE-RVD (BNP and Tnl p < 0.05, systolic pulmonary pressure p < 0.001). COULSION: Our data sustain the utility of BNP and Tnl as...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
