Why the study?
How does pulmonary blood volume correlate with pulmonary symptoms and haemodynamic parameters in patients with mitral valve disease compared to normal healthy volunteers?
How does pulmonary blood volume correlate with pulmonary symptoms and haemodynamic parameters in patients with mitral valve disease compared to normal healthy volunteers?
This study aimed to establish the normal range of pulmonary blood volume and its correlation with symptoms and hemodynamics in mitral valve disease.
Provides normative pulmonary blood volume data in mitral valve disease; symptom and hemodynamic correlations remain hypothesis-generating and should not yet change practice.
Various haemodynamic parameters in patients with mitral stenosis have been extensively studied but only a few measure ments of the pulmonary blood volume are available (Milnor et al., 1960 ; Dock et al., 1961 ; McGaff et al., 1963 ; Schreiner et al., 1963 ; Yu et al., 1963). Furthermore, no worker has correlated the pulmonary symptoms of patients with mitral stenosis to their pulmonary blood volume. The pulmonary blood volume estimated in 33 patients with mitral valve disease and 15 normal healthy volunteers forms the basis of this report. This study was undertaken to delineate the range of pulmonary blood volume in normal persons and to correlate pulmonary symptoms to pulmonary blood volume and other haemodynamic para meters in patients with mitral valve disease.
