Key result
Acute moderate exercise in healthy subjects significantly increased main pulmonary artery pulse wave velocity from 1.6 m/s at rest to 3.6 m/s and decreased relative area change from 0.34 to 0.24.
Why the study?
Does exercise stress alter pulmonary artery stiffness measured non-invasively by cardiovascular magnetic resonance in healthy subjects?
Cross-Sectional (n=21)

Absolute Event Rate: 3.6% vs 1.6%
p-value: p=<0.05
Cardiovascular magnetic resonance can non-invasively detect increases in main pulmonary artery stiffness during acute moderate exercise in healthy subjects.

CMR detects exercise-induced pulmonary artery stiffening in healthy subjects; hypothesis-generating for pulmonary vascular disease and should not yet change practice.
Forouzan et al. (2015) conducted a cross-sectional in Healthy (n=21). Acute moderate exercise vs. Rest was evaluated on Main pulmonary artery pulse wave velocity (MPA PWV) (p=<0.05). Acute moderate exercise in healthy subjects significantly increased main pulmonary artery pulse wave velocity from 1.6 m/s at rest to 3.6 m/s and decreased relative area change from 0.34 to 0.24.
