BACKGROUND Circulating cardiac troponin T, a marker of cardiomyocyte injury, predicts adverse outcome in patients with heart failure (HF) but is detectable in only a small fraction of those with chronic stable HF. We assessed the prognostic value of circulating cardiac troponin T in patients with stable chronic HF with a traditional (cTnT) and a new precommercial highly sensitive assay (hsTnT)....

BACKGROUND Cardiac troponin concentrations are used to identify patients who would benefit from urgent revascularization for acute coronary syndromes. We hypothesized that they might be used in patients with stable ischemic heart disease to identify those at high risk for cardiovascular events who might also benefit from prompt coronary revascularization. METHODS We measured the cardiac tropo...

Several studies have reported that the antioxidant properties of melatonin can provide cardiac protection through scavenging of free radicals. This study sought to investigate the efficacy of melatonin on cardiac biomarkers, myocardial-specific protein high sensitive troponin-T (hs-TnT) and creatine kinase-MB (CK-MB), in patients with ST-segment elevation myocardial infarction (STEMI) undergoin...

High serum levels of T troponin (TnT) have been described in patients with nonischemic myocardiopathies as markers of myocardial damage. We aimed to determine whether a highly sensitive TnT assay could identify patients with early stage chronic Chagas disease cardiopathy. We studied 39 outpatients with a serologic diagnosis of Chagas disease by clinical examination, electrocardiogram and echoca...

BACKGROUND The prognostic value of biochemical markers in relation to time since onset of chest pain was evaluated in an emergency room with a chest pain unit. METHODS In a single-center, prospective study we included 321 consecutive patients admitted to the emergency room with suspected unstable angina IIIB and an evolution of less than 12 hours. Blood samples were collected for CPK, CPK MB ...

STUDY OBJECTIVE Myocardial contusion may induce life-threatening complications, but its diagnosis is difficult. Circulating cardiac troponin T is considered a highly sensitive and specific marker of myocardial cell injury. We investigate the value of cardiac troponin T measurement in the diagnosis of myocardial contusion. DESIGN Prospective study. SETTING Level 1 trauma center. METHODS We...

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...

OBJECTIVE This study explored the relationship between coronary atherosclerotic plaque burden and quantifiable circulating levels of troponin measured with a recently introduced high sensitive cardiac troponin T (hs-cTnT) assay. METHODS AND RESULTS Cardiac patients suspected of having coronary artery disease (CAD) but without acute coronary syndrome were studied. Cardiac troponin T levels wer...
