Abstract
Objectives. Our aim was to investigate the associations between B-type natriuretic peptide (NT-proBNP), troponin T (TnT) and C-reactive protein (CRP) and changes in left ventricular function and size after acute coronary syndrome. Design. In 119 patients admitted for non-ST-elevation acute coronary syndrome, echocardiography and blood sampling were performed prior to coronary angiography. Echocardiography was repeated at follow-up after 8 ± 3 months. Left ventricular function was assessed by speckle tracking echocardiography. In 50 patients, infarct size was determined by magnetic resonance imaging. The associations between baseline levels of NT-proBNP, TnT and CRP and myocardial functional recovery, left ventricular intraventricular volumes and infarct size were determined by linear regression. Results. All three biomarkers were associated with myocardial dysfunction at baseline. However, high levels of NT-proBNP were associated with better myocardial recovery, as measured by global longitudinal strain, even after adjusting for other factors potentially influencing myocardial recovery. Conclusion. Elevated levels of NT-proBNP at baseline are independently associated with improved myocardial performance 8 months after non-ST-elevation acute coronary syndrome.
