Kadar N-Terminal Pro-Brain Natriuretic Peptide sebagai Prediktor Luaran Klinis Sindrom Koroner Akut (The Role of NT-proBNP as Clinical Outcome Predictor for Acute Coronary Syndromes)

---

Plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels may reflect the severity of ischemia, although there is no necrosis. A transient ischemia which can increase the heart wall stretch would induces BNP synthesis and release. Synthesis and release of BNP are comparable with the severity of ischemia. The aim of this study was to analyze whether NT-proBNP levels in patients with acute coronary syndrome (ACS) can be used as a predictor for clinical outcome. Studies was held since January to March 2010. Subject were patients with ACS who came to emergency room Dr. Hasan Sadikin Hospital Bandung and were clinically diagnosed according to World Health Organization criteria. Subjects which were suited with the inclusion criteria, stored until assayed. NT-pro BNP concentration was examined by electrochemiluminescence immunoassay method along with creatine kinase muscle brain (enzymatic method) and cardiac troponin T (quantitative method). Statistical analysis was performed using the one-sample Kolmogorov-Smirnov test for verifying normality, normally distributed data were analyzed using parametric analysis and abnormal distributed data was assayed using multiple logistic regression analysis to determine the parameters which can be used as predictor for clinical outcome in patients with ACS. Multiple logistic regression analysis on 83 subjects showed predictive value of NT-proBNP levels with OR=1.00, which mean there was no different likelihood in patients with high and low concentration of NT-proBNP to have longer hospitality duration. NT-proBNP β coefficient of 0.001 states that every addition of 1,000 pg/mL of NT-proBNP concentration will increase the length of hospitality duration for one day. On convalesce subjects, the most significant predictive value for predicting clinical outcome cTnT was more better than NT-proBNP concentration in patients with ACS (OR=32.53, 95%CI; 0.58–1,819.26). In conclusions, NT-proBNP is not a major predictor of clinical outome in ACS. NT-proBNP levels of >826.7 pg/mL implies a poor prognosis to death.
