چکیده

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 infarction (mi). patients with a negative troponin can be investigated further with computed tomographic coronary angiography (ctca) or exercise electrocardiography (ecg). a review of cardiac biomarkers as screening test in acute chest pain over 15 years was conducted. separate searches were under taken for biomarkers. we searched electronic databases up to 2004-2014, reviewed citation lists and contacted experts to identify diagnostic and prognostic studies comparing a relevant index test (biomarker, ctca or exercise ecg) to the appropriate reference standard. we classified studies to two part early rise biomarkers, high sensitivity biomarkers. conclusion: although presentation troponin has suboptimal sensitivity, measurement of a 10-hour troponin level is unlikely to be cost-effective in most scenarios compared with a high sensitivity presentation troponin. measurement of cardiac troponin using a sensitive method was the best test for the early diagnosis of an acute myocardial infarction (ami). measurement of myoglobin or creatine kinase-mb (ck-mb) in addition to a sensitive troponin test is not recommended. heart-type fatty acid-binding protein (h-fabp) shows promise as an early marker and requires further study.

Emergency medicine in Japan.

There have been few reports published in English on emergency medicine (EM) in Japan; the main reason for this is that the concept of EM was different in Japan from that in western countries.

There were no emergency medicine specialists, and so su...
