the registry of myocardial infarctions (mi registry) is a national registry in iran that collects and reports the data on myocardial infarctions. its main advantage is that it covers the whole country and is mandatory for hospitals to register the mi cases in it. then, the qualified individuals at the provincial and national levels can get intended reports and make appropriate decisions. such r...

Acute liver failure in ICU patients is an often fatal condition in which many patients may die of multiple organ failure in the absence of liver transplantation. In this setting, cardiac injury may be associated with or precipitate a fatal outcome. Troponin-I is a well-established, specific, and sensitive surrogate of acute coronaropathy, with both diagnostic and prognostic value. Troponin-I el...

BACKGROUND The purpose of this research was to determine the relation between negative or positive qualitative troponin I test and the short term prognosis of patients presenting to emergency department with chest pain or angina equivalent symptoms. METHODS we assessed the qualitative rapid troponin I in patients with chest pain or angina equivalent symptoms after at least 4 hours and then we...

Objective: Heart transplant recipients undergo a number of invasive endomyocardial biopsies to screen for rejection. Serum assays of troponin T and/or I may provide a less invasive alternative. The purpose of this study was to evaluate troponin T and I as markers of cardiac transplant rejection. Methods: We conducted a prospective analysis comparing troponin T and I levels to biopsy results in ...

1. Myofibrils from human skeletal muscle contained regulatory proteins exhibiting similar electrophoretic behaviour to those present in rabbit skeletal muscle. 2. All human skeletal muscles examined contained two forms of troponin I corresponding to the forms already characterized in fast and slow rabbit muscle. 3. The ratios of the amounts of the two forms of troponin I in different human skel...

An increased level of serum cardiac troponin I is a specific biomarker for myocardial injury. The objective of this study was to evaluate the changes in cardiac troponin I levels to determine myocardial injury following diagnostic cardiac catheterization. A prospective cohort study was carried out between July 1 2006 and March 31 2012 among patients who underwent diagnostic cardiac catheterizat...

OBJECTIVE This study aims to determine whether the prognostic significance of troponins in acute coronary syndrome in predicting mortality varies by age, and if so, to what extent when other prognostic indicators are considered. METHODS We analysed Myocardial Ischemia National Audit Project registry data collected between January 2006 and December 2010 and followed up this cohort for all-caus...
