PURPOSE The purpose of this retrospective study was to evaluate cardiac troponin-I (cTnI) as a 28-day mortality prognosticator and predictor for a drotrecogin alfa (activated) (DrotAA) survival benefit in recombinant human activated Protein C Worldwide Evaluation in Severe Sepsis patients. METHODS Cardiac troponin-I was measured using the Access AccuTnI Troponin I assay (Beckman Coulter, Full...

Cardiac troponin I (cTnI) mutations have been linked to the development of restrictive cardiomyopathy (RCM) in human patients. We modeled one mutation in human cTnI C-terminus, arginine192-->histidine (R192H) by cardiac specific expression of the mutated protein (cTnI(193His) in mouse sequence) in transgenic mice. Heart tissue sections revealed neither significant hypertrophy nor ventricular di...

BACKGROUND & OBJECTIVES Accurate and rapid diagnosis of acute myocardial infarction (MI) is of major clinical significance. The troponin is the biomarker of choice for detection of cardiac injury. The objective of this study was to identify salivary levels of cardiac troponin I (cTnI) in patients with acute MI. METHODS Thirty patients with acute MI and 28 normal healthy individuals were inclu...

The aim of this study was to observe the effect of Rehmannia glutinosa oligosaccharide (RGO) on differentiation of bone marrow mesenchymal stem cells (MSCs) into cardiomyocyte-like cells . Rat MSCs were isolated, treated, and grouped as follows: RGO treatment group, 5-azacytidine (5-aza) treatment group, RGO + 5-aza treatment group, and control group. Following a four-week induction period, car...

OBJECTIVE To measure serum cardiac troponin I (cTnI) concentrations in orphaned harbor seal (Phoca vitulina) pups at various points during rehabilitation in a seal rescue center and determine whether cTnI concentration was associated with survival during rehabilitation and duration of rehabilitation. DESIGN Serial cross-sectional study. ANIMALS Fifty-five 2- to 9-day-old harbor seal pups. PROCE...

Mutations in human cardiac troponin I (cTnI) have been associated with restrictive, dilated, and hypertrophic cardiomyopathies. The most commonly occurring residue on cTnI associated with familial hypertrophic cardiomyopathy (FHC) is arginine (R), which is also the most common residue at which multiple mutations occur. Two FHC mutations are known to occur at cTnI arginine 204, R204C and R204H, ...

BACKGROUND Myocardial injury can be detected by cardiac troponin I (cTnI) concentration, which appears to be a predictor of short-term death in critically ill patients. It is unknown if the best prognostic indicator of short-term survival is cTnI measurement at admission or at later time points. HYPOTHESIS/OBJECTIVES Measuring cTnI with a high-sensitivity (HS) test at different time points af...

Increased cardiac troponin I (cTnI), a marker for cardiac damage, has been reported after strenuous exercise in young subjects. However, little is known about changes in cTnI after moderate-intensity exercise in a heterogenous population or which factors may contribute to this change in cTnI levels. We examined cTnI levels before and immediately after each day of a 4-day long-distance walking e...

BACKGROUND Elevated cardiac troponin (cTn) levels have been reported to predict adverse cardiovascular outcomes in asymptomatic ESRD patients. However, the prognostic value of elevated cTn levels associated with sepsis in ESRD patients is unknown. Therefore, this study aimed to elucidate the clinical implications of elevated cTnI levels in ESRD patients with sepsis. METHODS Of the 305 ESRD pa...

Valvular heart disease is a common cardiac disease in our country. The valvular heart disease which we face in our day to day hospital and private practice is due to chronic sequlae of rheumatic fever. In chronic rheumatic heart disease mitral valve is affected in more than 90% of cases and aortic valve is the next most frequently affected valve. This study was done to evaluate the association ...
