Objective: To determine high sensitivity C-reactive protein (hsCRP) levels in patients with acute myocardial infarction (AMI) and its correlation with classical enzyme markers of myocardial damage. Study Design: Observational study. Place and Duration of Study: Department of Emergency Medicine at King Khalid University Hospital, King Saud University, Riyadh and Department of Physiology, from August 2010 to December 2011. Methodology: Consecutive eligible patients with either ST elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) who were admitted to the Emergency Department of King Khalid University Hospital were recruited. A total of 71 subjects were finally selected for the study. The hsCRP, Troponin I (Trop I), creatine kinase myocardial bound (CK-MB), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) concentrations of all patients with an acute myocardial infarction (AMI) were measured. Results: Among all patients 34 (47.9%) patients had diabetes mellitus, 21 (29.6%) were hypertensive, and 16 (22.5%) had no associated illness. Patients with STEMI had significantly higher levels of CKMB (p=0.0348), LDH (p=0.0471) and hsCRP (p=0.0231) compared to NSTEMI patients. While the differences were non-significant for To I (p=0.7022), AST (p=0.9729) and Lp(a) (p=0.5985). Spearman's correlations revealed that CRP correlated significantly with Trop I, CK-MB and LDH. There was a significant predictive relationship of hsCRP with Trop I, LDH and CK-MB while with AST it was non-significant. Conclusion: High sensitivity CRP levels is a significant predictor of standard markers for myocardial damage and it may be a useful prognostic marker in acute coronary syndromes.
