Abstract

This study was designed to determine whether the restrictive filling transmitral flow velocity pattern is associated with increased plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). It was also designed to evaluate the prognostic value of these parameters from patients with chronic congestive heart failure (CHF) admitted for episodes of acute decompensation. We performed Doppler echocardiography, measured plasma levels of ANP and BNP in 33 patients at the time of admission, and assessed the subsequent cardiac mortality for 3 months. Eleven patients (33%) had a restrictive filling pattern of deceleration time (DcT) < 120 ms. Plasma ANP and BNP levels were markedly increased in all patients to 189 +/- 145pg/ml and 865 +/- 559 pg/ml, respectively. Seventeen patients (52%) showedmore than 700 pg/ml of plasma levels of BNP. There was a significant correlation of DcT with the plasma ANP level (r = -0.41, P = 0.017), and a better correlation of DcT with the plasma BNP level(r = -0.50, P = 0.003). The combined index of both shorter DcT ((120 ms) and higher plasma BNP levels (>700 pg/ml) was the best predictor of cardiac mortality by Cox univariate analysis (chi (2) = 5.87, P = 0.015). Furthermore, the sensitivity and specificity of this index for the detection of cardiac mortality were 80% and 86%, respectively. In conclusion, the combined analysis of the Doppler transmitral flow velocity pattern and measurement of the plasma BNP level is noteworthy since it is noninvasive and convenient. Moreover, it is extremely useful in predicting the prognosis for patients with chronic CHF admitted forepisodes of acute decompensation.
