background: there is evidence that electrocardiographic (ecg) changes occur during elective cesarean section in parturients. these changes, mostly in the form of st-segment depression, have been noted in either regional anesthesia or general anesthesia. we performed this study to compare hemodynamic variables and electrocardiographic changes suggestive of myocardial ischemia following administr...

A 74-year-old man was admitted for chest infection with acute exacerbation of chronic obstructive pulmonary disease. He was incidentally found to have an increased serum level of cardiac troponin I, despite the absence of symptoms and electrocardiographic evidence of ischaemic heart disease. Troponin I became undetectable after the serum was treated with polyethylene glycol, which removed any i...

Two patients were investigated for unexplained increases in troponin T. In the first patient, who had rhabdomyolysis and acute renal failure, troponin T reached a peak value of 13.50 micrograms/L (67.5-fold the upper reference limit). The second patient had chronic renal failure and the troponin T peak value was 2.85 micrograms/L (14.3-fold the upper reference limit). Clinical investigations in...

The aim of this study was to prospectively evaluate the accuracy of quantitative cardiac computed tomography (CT) parameters and two cardiac biomarkers (N-terminal-pro-brain natriuretic peptide (NT-pro-BNP) and troponin I), alone and in combination, for predicting right ventricular dysfunction (RVD) in patients with acute pulmonary embolism. 557 consecutive patients with suspected pulmonary emb...

Introduction: The aim of this study was determination of troponin I at serum using Architect (Abbott) and AxSYM System (Abbott). Troponin is regulatory subunit of the troponin complex associate with actin filament within muscle cells and it is a marker for diagnosis of myocardial damage. Methods: We used Architect STAT chemiluminescent microparticle immunoassay (CMIA) and AxSYM microparticle En...

Cardiac troponin I is a potentially useful test to identify cardiac muscle damage in the horse. Measurements of cardiac troponin I from serum or heparinised plasma samples from 23 clinically normal Thoroughbred horses in race training were analysed through a standard Australian commercial laboratory using the ADVIA Centaur Assay. The cardiac troponin I concentrations were < 0.15 microg/L from a...

INTRODUCTION The high-sensitive C-reactive protein (HS-CRP) assay is being increasingly used as a marker for cardiac risk assessment and as a prognostic tool in heart disease. In current study, we assessed the relationship between serum level of HS-CRP and extension of myocardial involvement in acute myocardial infarction. METHODS In a cross-sectional study, 50 patients with the final diagnos...

Background: Some recent studies have shown that troponin may have a Prognostic value in patients with ischemic stroke. This study seeks to to evaluate the prognostic value of troponin on 3 months mortality and recurrence in patients with ischemic stroke. Method: In this study 63 patients with ischemic stroke were evaluated. Embolic and lacunar stroke were excl...
