May aid non-invasive LVEDP estimation; leaves open prospective validation before clinical adoption.
Do plasma BNP and ANP concentrations correlate with left ventricular end-diastolic pressure and other hemodynamic parameters in patients undergoing diagnostic cardiac catheterization?
Plasma BNP and ANP levels strongly correlate with left ventricular end-diastolic pressure, suggesting they are useful non-invasive indices of cardiac performance.
Haug et al. (1993) studied this question.
