AIMS Elevation of troponin T in patients with unstable angina is predictive of adverse outcomes. Since no advanced therapeutic concept for such high-risk patients has been established, we investigated cardiac risk prior to, during, and after coronary revascularization in patients with unstable angina stratified according to the troponin T status. METHODS AND RESULTS Out of 351 patients with u...

OBJECTIVES This study evaluates the concept and diagnostic efficacy of using serum troponin T for the detection of cardiac graft rejection. BACKGROUND Cardiac troponin T is a cardiospecific myofibrillar protein, which is only detectable in the circulation after cardiac myocyte damage. It might be expected to be released during acute heart allograft rejection, allowing noninvasive rejection di...

BACKGROUND The prognostic usefulness of troponin enzymes in end-stage renal disease (ESRD) patients is controversial. To resolve this uncertainty of troponin as a prognostic tool, we conducted a systematic review to quantify the association between elevated troponin I or T and long-term total mortality among ESRD patients not suspected of having acute coronary syndrome. METHODS AND RESULTS We...

The fraction of polyclonal caldesmon antibodies cross-reacting with rabbit skeletal troponin T are shown to compete with smooth muscle tropomyosin for caldesmon and troponin T, as revealed by ELISA method. The epitope recognized by these antibodies was also found in Mr 77 kDa non-muscle caldesmon. These results provide functional confirmation for the suggestion that the regions of amino acid se...

Cardiac biomarkers provide prognostic information in light-chain amyloidosis (AL). Thus, a novel high-sensitivity cardiac troponin T (hs-TnT) assay may improve risk stratification. hs-TnT was assessed in 163 patients. Blood levels were higher with cardiac than renal or other organ involvement and were related to the severity of cardiac involvement. Increased sensitivity was not associated with ...

Abstract Background There have been no cardiac biomarkers used in the diagnosis of unstable angina. In this study, we examined high sensitive troponin T and I as a marker to differentiate patients with angina from stable Methods A total 816 (59 AMI, 94 angina, 99 623 healthy individuals) were included. All had glomerular filtration rate ≥60 mL/min/1.73 m2. Leftover serum samples obtained who vi...

By means of new or modified procedures troponin-tropomyosin complex was fractionated into three components plus tropomyosin, and then reconstituted in the absence of urea. Tropomyosin was separated from troponin by hydroxyapatite column chromatography, a method giving sharper separation than the previously used technique of isoelectric precipitation. The chromatography also separated the tropom...

OBJECTIVE To measure plasma interferon gamma, monocyte chemotactic protein-1 (MCP-1), and interleukin 6 and to assess their correlation with cardiac troponin T in unstable angina. DESIGN Blood sampling in patients undergoing coronary arteriography for known or suspected ischaemic heart disease. PATIENTS 76 patients divided in three groups: 29 with unstable angina (group 1), 28 with stable a...

BACKGROUND AND AIMS MHC class I polypeptide-related chain A (MICA) molecule is induced in response to viral infection, various types of stress, such as endoplasmic reticulum stress, and ischemia or/and reperfusion, by which MICA was shed from the cell surface into the extracellular domain, generating a soluble form (sMICA). In the present study, we designed to investigate the serum sMICA level ...
