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.

Copeptin levels in conjunction with cardiac troponin may be used to rule out early myocardial infarction in patients presenting with chest pain. Raised pre-operative copeptin has been shown to be asso...
This study aimed to determine the diagnostic accuracy of adding copeptin to cardiac troponin (cTn) on admission to the emergency department (ED) for non-ST elevation myocardial infarction (NSTEMI) com...
Symptoms indicating acute coronary syndrome are commonly seen in emergency rooms, but only 10% of patients are actually diagnosed with acute myocardial infarction (AMI). The Guidelines for the diagnos...
The oxygen supply-demand imbalance is the fundamental pathophysiology of myocardial infarction (MI). Reducing myocardial oxygen consumption (MVO) in acute MI (AMI) reduces infarct size. Since left ven...
Background Acute myocardial infarction is a major cause of death all over the world. Irisin is a novel myokine released after exercise. This work aimed to study the correlation between the serum irisi...
ST-elevation myocardial infarction (STEMI) has a serious health threaten to population. PCI, which can timely restore the blood flow to the ischemic myocardium, is a well-proved measure in...
Registry of an interventional Study-proved Strategy (BIC-8) using Copeptin and Troponin for the Early Rule-Out of Acute Myocardial Infarction (AMI) in Patients with Suspected Acute Coronar...
While troponin is not detectable until several hours after an Acute Myocardial Infarction (AMI), copeptin is expected to be elevated very early after an AMI. A combination of both markers ...
Every year > 50.000 people in Denmark are hospitalized with a suspected acute myocardial infarction (AMI). The majority has other explanations of their chest discomfort and most are discha...
The size of the infarct is particularly important prognostic marker. It is clearly established that the extent of the infarct is not only correlated to mortality, but also long-term advers...
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.

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.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
