Fig. 5From: Non-invasive measurement using cardiovascular magnetic resonance of changes in pulmonary artery stiffness with exerciseEffect of different exercise-stress stages on MPA-RAC. Average RAC data from 15 subjects at different stress conditions indicates lower RAC is associated with higher exercise workload (ST1 = 35 W, ST2 = 45 W). †P < 0.05, vs. Rest. The data in the bar graph represent the mean ± SDBack to article page
