Key result
Supine exercise in patients with acquired heart disease resulted in statistically significant increases in pulmonary blood volume (88.6 ± 20.9 ml/m2) and central blood volume.

Does supine exercise affect pulmonary blood volume in patients with acquired heart disease?
Supine exercise increases pulmonary and central blood volumes in patients with acquired heart disease, suggesting passive expansion of the pulmonary vascular bed.
Schreiner et al. (1963) conducted an observational in Acquired heart disease (valvular heart disease and cardiomyopathy) (n=15). Supine exercise was evaluated on Pulmonary blood volume and central blood volume. Supine exercise in patients with acquired heart disease resulted in statistically significant increases in pulmonary blood volume (88.6 ± 20.9 ml/m2) and central blood volume.
