Exercise increases functional MR in HF; hypothesis-generating for dynamic assessment and should not yet change practice.
Does dynamic cycle exercise increase functional mitral regurgitation in patients with chronic heart failure?
Functional mitral regurgitation worsens during exercise in patients with chronic heart failure, highlighting the importance of exercise evaluation in this population.
Takano et al. (2006) studied this question.
