Abstract

Introduction: Echocardiographic indices can form the basis of the diagnosis of systolic and diastolic left ventricular (LV) dysfunction in patients with Mitral regurgitation (MR). However, using echocardiography alone may bring us to a diagnostic dead-end. The aim of this study was to compare N-Terminal pro B-natriuretic peptide (BNP) and echocardiographic indices in patients with mitral regurgitation.

Methods: 2D and Doppler echocardiography and BNP serum level were obtained from 54 patients with organic mild, moderate and severe MR.

Results: BNP LEVELS WERE INCREASED WITH SYMPTOMS IN PATIENTS WITH MITRAL REGURGITATION (NYHAI: 5.7 ± 1.1, NYHAII: 6.9 ± 1.5, NYHAIII: 8.3 ± 2 pg/ml, P < 0.001). BNP plasma level were significantly correlated with MPI (myocardial performance index) (r = 0.399, P = 0.004), and following echocardiographic indices: LVEDV (r = 0.45, P < 0.001), LVESV (r = 0.54, P < 0.001), LVEDD (r = 0.48, P < 0.001), LVESD (r = 0.54, P < 0.001), dp/dt (r = -0.32, P = 0.019) and SPAP (r = 0.4, P = 0.006).

Conclusion: The present study showed that BNP may be useful in patients with MR and may confirm echocardiographic indices.
