Troponin and C-reactive Protein in Risk Stratification after Myocardial Infarction

Abstract

Summary The aim of this study was to investigate the prognostic significance of troponin I, C-reactive protein and risk factors for the occurrence of complications after myocardial infarction. Troponin I and C-reactive protein values were analyzed in 38% of patients with complications (postinfarction angina, ventricular fibrillation, heart failure and fatal outcome) and in 62% of patients without complications. Values wererecorded on admission and between the eighth and tenth day of hospitalization. It was found that a larger number of risk factors (p = 0.00), diabetes mellitus (p = 0.02) and smoking (p = 0.01) were significantly associated with the complications. It was shown that hypertension increases the risk of developing heart failure after acute myocardial infarction (p = 0.02). It resulted with statistically non-significant difference in the observed values of troponin I between the group of patients with complications and the group without them (p = 0.22, p = 0.327). There was a statistically significant difference in the observed values of C-reactive protein in the two groups of patients (p = 0.00, p = 0.01). It can be concluded that the values of troponin I had no prognostic significance in risk stratification, while the values of C-reactive protein, individual risk factors and a large numberof risk factors hadsignificance in risk stratification after myocardial infarction.
