Normal healthy aging results in changes in Doppler indexes of diastolic function. One widely accepted explanation for these alterations that is based on animal data is an age-associated impairment of myocardial relaxation resulting from abnormal myocyte calcium handling. However, an alternative theory based on altered left atrial compliance with aging has been proposed in which early left atrial pressure could be low in the aged heart but rise rapidly during atrial diastole, resulting in a higher late atrial pressure and thus a normal mean pressure. We sought to explore this issue directly by performing a detailed analysis of the pulmonary capillary wedge pressure waveform obtained by right-heart catheterization during 5 different loading conditions.
