Summary of "Can copeptin and troponin T ratio predict final infarct size and myocardial salvage index in patients with ST-elevation myocardial infarction: A sub-study of the DANAMI-3 trial."

Primary percutaneous coronary intervention (pPCI) is recommended in patients presenting with ST-elevation myocardial infarction (STEMI) within <12 h of symptom onset. However, patients-reported symptom duration is not always reliable. Cardiac specific troponin T (cTnT) and the endogenous stress marker copeptin have different temporal release patterns for myocardial infarction MI. We hypothesized that copeptin/troponin-ratio is associated to the duration of coronary occlusion and therefore inversely proportional to myocardial salvage.

Medical and Biotech [MESH] Definitions

Recording of regional electrophysiological information by analysis of surface potentials to give a complete picture of the effects of the currents from the heart on the body surface. It has been applied to the diagnosis of old inferior myocardial infarction, localization of the bypass pathway in Wolff-Parkinson-White syndrome, recognition of ventricular hypertrophy, estimation of the size of a myocardial infarct, and the effects of different interventions designed to reduce infarct size. The limiting factor at present is the complexity of the recording and analysis, which requires 100 or more electrodes, sophisticated instrumentation, and dedicated personnel. (Braunwald, Heart Disease, 4th ed)

A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).

One of the three polypeptide chains that make up the TROPONIN complex. It is a cardiac-specific protein that binds to TROPOMYOSIN. It is released from damaged or injured heart muscle cells (MYOCYTES, CARDIAC). Defects in the gene encoding troponin T result in FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.

The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases. The disease-odds ratio for a cohort or cross section is the ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed. The prevalence-odds ratio refers to an odds ratio derived cross-sectionally from studies of prevalent cases.

One of the three polypeptide chains that make up the TROPONIN complex. It inhibits F-actin-myosin interactions.
