Prognostic value of C-Reactive Protein in Acute Coronary Syndromes

Introduction: Coronary artery disease (CAD) is among the most common, serious, chronic and life- threatening illnesses in the world. CAD represents a spectrum of conditions, with acute myocardial infarction at one end of it and silent ischemia at the other. There is growing evidence on importance of prognosis of C- reactive protein (CPR) in unstable angina and this protein is a maker of an adverse prognosis. Materials and Methods: In this cross- sectional research. We study all of the patients that admitted in the coronary care unit of the Shahid Rahimi hospital with unstable angina (n=32) and acute myocardial infarction (n=32), but exclude the patients with exclusion criteria. Complete clinical data and blood samples for laboratory measurements were collected on admission. A baseline ECG were obtained at entry and 12 hours later. A CFM echocardiogram was performed within initial 24 hours. Serum CPR levels were measured on admission and at time of hospital discharge. All patients were followed up for 14 days after discharge. Findings: Patients with MI showed a striking higher CPR during the duty period than with UA. The occurrence of cardiac events at 14 day follow up was related to CPR level at 48 hours and hospital discharge (p=0.02). CPR levels correlated inversely with ejection fraction (r=-0.44). Conclusion: Our data demonstrated that the CPR were significantly higher in patients with acute myocardial infraction than patients with unstable angina. Elevated levels of CPR were associated with cardiac events out of hospital during a 14- day follow up.
