I n 2000, the European Society of Cardiology and the American College of Cardiology presented new diagnostic criteria for myocardial infarction (MI) which placed a greater emphasis on cardiac markers by stating that any elevation in cardiac troponin T (cTnT) or cardiac troponin I (cTnI) above the 99th centile of normal was sufficient to diagnose a MI. Recent studies since then have shown that t...

The echocardiography showed mild dilatation of the left ventricle (end-diastolic volume: 141 ml, end-systolic volume: 66 ml), mild reduction of the left ventricular ejection fraction (53%) with apical ballooning [Figure 1a, yellow arrow], degenerative moderate-to-severe mitral regurgitation [Figure 1b], and moderate aortic regurgitation [Figure 1c]. Sinus rhythm with weak negative T-waves in in...

Objective: Exercise and nutrition as life style modification strategies for the prevention and control of diabetes are considered. The aim of present study was to assess the effects of saffron consumption and aerobic exercises on serum levels of Heart-type fatty acid binding protein (HFABP) and Troponin T in type2 diabetes (T2DM) patients. Materials and Methods: This study was a quasi-experime...

OBJECTIVE To investigate the intraoperative release of troponin T during uncomplicated coronary artery surgery and to determine its relation to ischaemic time and to recovery of left ventricular function and oxidative metabolism. DESIGN A prospective observational study. SETTING Cardiac surgical unit in a tertiary referral centre. METHODS Troponin T, creatine kinase, and lactate were anal...

We have investigated the binding of bepridil to calcium-saturated cardiac troponin C in a cardiac troponin C/troponin I complex. Nuclear magnetic resonance spectroscopy and [(15)N,(2)H]cardiac troponin C permitted the mapping of bepridil-induced amide proton chemical shifts. A single bepridil-binding site in the regulatory domain was found with an affinity constant of approximately 140 microM(-...

Cardiac phospholipid-sensitive Ca2+-dependent protein kinase phosphorylated cardiac troponin inhibitory subunit (troponin I) and tropomyosin-binding subunit (troponin T), present either as the free form or as the troponin-tropomyosin complex. Exhaustive phosphorylation of troponin I and of troponin T revealed that 1.7 and 2 mol of phosphate was incorporated/mol of the subunits respectively. Cyc...

OBJECTIVE To compare troponin I levels in plasma before and after specimen recentrifugation. METHODS Over a period of 24 consecutive days, we recentrifuged 189 plasma specimens in which the troponin I level was higher than the positivity cut off (60 ng/L) and then remeasured the troponin I. RESULTS Two-tailed Wilcoxon matched-pairs test results identified a statistically significant differe...

BACKGROUND Changes in high sensitivity cardiac troponin-T (hs-cTnT) concentrations may reflect either acute myocardial injury or biological variation. Distinguishing between these entities is essential to accurate diagnosis, however, the biological variation of hs-cTnT in dialysis population is currently unknown. We sought to estimate the within- and between-person coefficients of variation of ...

Abstract Background Patients with sepsis and septic shock often have elevated troponin T levels indicating acute myocardial injury. Studies investigating the relationship between as a predictor for mortality in been contradictory. Purpose To investigate if first in-hospital sampled plasma value is associated one-year independent of comorbidities, Sequential Organ Failure Assessment (SOFA)-score...
