Appropriate roles of cardiac troponins in evaluating patients with chest pain.

BACKGROUND Diagnosis of acute myocardial infarction relies upon the clinical history, interpretation of the electrocardiogram, and measurement of serum levels of cardiac enzymes. Newer biochemical markers of myocardial injury, such as cardiac troponin I and cardiac troponin T, are now being used instead of or along with the standard markers, the MB isoenzyme of creatine kinase (CK-MB) and lacta...

Cardiac troponins

Objective: To review the use of cardiac troponins as biomarkers for myocardial injury in human and veterinary medicine. Data sources: Data sources included scientific reviews and original research publications. Human data synthesis: Cardiac troponins have been extensively studied in human medicine. Finding an elevated cardiac troponin level carries important diagnostic and prognostic informatio...

Unexplained (non-cardiac) chest pain.

Non-cardiac chest pain is considered to be central chest pain that resembles angina yet, after appropriate investigation, its cause appears unrelated to the heart. The problem is common: one in four of the population have at least one episode over the course of a year and patients with chest pain account for about 5% of all presentations to primary care physicians and emergency departments.1 Ev...
