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...

Cardiac troponin is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). The recent development of a high-sensitive cardiac troponin T (hs-cTnT) assay permits detection of very low levels of cTnT. Using the hs-cTnT assay improves the overall diagnostic accuracy in patients with suspected AMI, while a negative result also has a high negative predictive value. The gain ...

The rapid and reliable diagnosis of acute myocardial infarction is a major unmet clinical need. We conducted a multicenter study to examine the diagnostic accuracy of new, sensitive cardiac troponin assays performed on blood samples obtained in the emergency department from 718 consecutive patients who presented with symptoms suggestive of acute myocardial infarction. Cardiac troponin concentra...

BACKGROUND The rapid and reliable diagnosis of acute myocardial infarction is a major unmet clinical need.

BACKGROUND Postoperative non-cardiac complication rates are as high as 11-28% after high-risk abdominal procedures. Emerging evidence indicates that postoperative cardiac troponin T elevations are associated with adverse outcome in non-cardiac surgery. The aim of this study was to determine the relationship between postoperative high-sensitive cardiac troponin T elevations and non-cardiac compl...

acute chest pain is an important and frequently occurring symptom in patients. chest pain is often a sign of ischemic heart disease. chest pain due to suspected acute coronary syndrome (acs) is responsible for a large and increasing number of hospital attendances and admissions. current practice for suspected acs involves troponin testing 10–12 hours after symptom onset to diagnose myocardial i...

Objective: Acute chest pain is an important and frequently occurring symptom in patients. Chest pain is often a sign of ischemic heart disease. Chest pain due to suspected Acute Coronary Syndrome (ACS) is responsible for a large and ijncreasing number of hospital attendances and admissions. Current practice for suspected ACS involves troponin testing 10–12 hours after symptom o...
