In order to investigate the relationship between left atrial pressure and volume, left atrial echograms and mean pulmonary wedge pressure were obtained on 64 patients with various cardiac diseases. A statistically significant relationship was found in the whole group (r = 0.67, p < 0.01), but there was a considerable degree of dispersion around the regression line. A good correlation was present in 6 patients with hypertrophic cardiomyopathy (r = 0.97, p < 0.01) and in 13 patients with long standing mitral valve disease (r = 0.85, p < 0.01). There was no correlation in coronary artery disease patients.

Abstract
In order to investigate the relationship between left atrial pressure and volume, left atrial echograms and mean pulmonary wedge pressure were obtained on 64 patients with various cardiac diseases. A statistically significant relationship was found in the whole group (r = 0.67, p < 0.01), but there was a considerable degree of dispersion around the regression line. A good correlation was present in 6 patients with hypertrophic cardiomyopathy (r = 0.97, p < 0.01) and in 13 patients with long standing mitral valve disease (r = 0.85, p < 0.01). There was no correlation in coronary artery disease patients.File in questo prodotto:
