Relationships of serum troponin T with ECG, colour doppler sonography of lower extremity venous and arterial blood gas findings in patients with acute pulmonary embolism

Pulmonary embolism is a prevalent and fatal pulmonary disease. In this study, the relationships between serum highly sensitive (hs) troponin T levels and findings of ECG, colour doppler sonography of lower extremity veins venous (CDS LEV) and also arterial blood gas (ABG) in normotensive patients with acute pulmonary embolism were investigated. A cross sectional study was carried out on 33 patients with acute pulmonary embolism who were hospitalized in Emam Khomeini Hospital, Tehran University of Medical Sciences between 2009 and 2010 (mean age, 49.3; 18 male and 15 female). (18 patients had with a normal hs-troponin T, lower than 14 pg/ml, and 15 patients had with elevated hs-troponin T.)with acute pulmonary embolism (mean age, 49.3; 18 male and 15 female) who were hospitalized in Emam Khomeini Hospital, Tehran University of Medical Sciences between 2009 and 2010 Serum hs-troponin T level was measured by ELISA highly sensitive method. The prevalence of T invert and S1Q3T3 patterns and also thrombosis in lower extremity deep venous were significantly higher in patients with elevated hs-troponin T. In addition, PCO2 and HCO3- levels were significantly lower in patients with elevated hs-troponin T levels. According to the results of the study, it seems that the elevated hs-troponin T accompanies with ECG and ABG findings and also with thrombosis in lower extremity deep venous prevalence in patients with acute pulmonary embolism.
