Comparison Between Biomarkers High-Sensitivity C-Reactive Protein and N-Terminal Probrain Natriuretic Peptide in Patients with Myocardial Infarction

Background: Elevated inflammatory markers have been associated with an increased risk of future cardiovascular events, acute myocardial infarction (MI), and illness in patients with stable or unstable coronary artery disease. Aim: The present study was comparison between high-sensitivity C-reactive protein (hsCRP), NTproBNP, TnT, and creatine kinase MB (CK-MB) in patient groups and control group. Materials and Methods: The diagnostic test blood glucose and lipid profile biochemical parameter were assessed using endpoint method. hsCRP kits for human were assessed using turbidimetric immunoassay method. Serum N-terminal probrain natriuretic peptide (NT-proBNP) levels were measured by automated immunoassay. Both cardiac TnT and CK-MB mass were measured with highly specific monoclonal antibodies in a sensitive chemiluminescence assay. Results: Comparing marker levels of the two groups, Mann–Whitney U test and independent sample t -test were used. The mean NT-proBNP (pg/ml) and hsCRP (mg/L) were found significantly different and almost 24- and 8-fold higher in cases as compared to controls (610.69 ± 25.28 vs. 25.28 ± 11.76, and 4.47 ± 1.62 vs 0.52 ± 0.23; all P < 0.01). Further, the CK-MB (IU/L) and TnT (pg/ml) (mean ± standard deviation) were also high in the case group than control (166.83 ± 27.8 vs. 98.03 ± 3.05; P < 0.01 and 135.44 ± 8.79 vs 96.46 ± 2.91; P < 0.01). Conclusion: Elevated level of NT-proBNP is a strong independent prognostic predictor in patients with myocardial infarction and positive correlation between NTproBNP with TnT and CK-MB with TnT and consumption of alcohol, smoking, and tobacco may be also a risk factor for myocardial infarction.
