Deliberate Self-Poisoning (DSP) or drug induced suicide is the most common method of suicide in the developed countries and is associated with significant morbidity and mortality (1-3). Factors associated with DSP include economic and social factors, culture, religion, and health (4-6). Other symptoms that may influence suicide encompass demographic information like age, sex, and, ethnicity (6-8)

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 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.
