ABSTRACT

BACKGROUND:

There are several echocardiographic parameters, such as early transmitral velocity/tissue Doppler mitral annular early diastolic velocity(E/Ea) or deceleration time, reported to be reliable indices to estimate pulmonary capillary wedge pressure(PCWP). Recently, B-type natriuretic peptide(BNP) level is also reported to increase in accordance with increased left ventricular filling pressure in systolic or diastolic heart failure. This study was performed to compare E/Ea and BNP for the ability to estimate PCWP.

METHODS:

Several echocardiographic Doppler parameters including especially E/Ea were obtained from transthoracic Doppler echocardiography. Simultaneously, serum BNP level and PCWP estimated by using Swan-Ganz catheter were obtained, respectively.

RESULTS:

E/Ea revealed a correlation of r=0.88 (p or =11 was the optimal cutoff to predict PCWP > or =15 mmHg (sensitivity, 94%; specificity, 90%), whereas the optimal BNP cutoff was > or =250 pg/mL (sensitivity, 52%; specificity, 74%).

CONCLUSION:

Mitral E/Ea has a better correlation with PCWP than BNP. Mitral E/Ea appears more sensitive and specific than BNP for PCWP > or =15 mmHg in cardiac patients.
