Why the study?
Does exercise pulmonary hypertension predict the occurrence of symptoms in asymptomatic patients with degenerative mitral regurgitation?
Does exercise pulmonary hypertension predict the occurrence of symptoms in asymptomatic patients with degenerative mitral regurgitation?
Exercise pulmonary hypertension (SPAP >56 mm Hg) is a strong independent predictor of symptom development in asymptomatic patients with degenerative mitral regurgitation, supporting the prognostic value of exercise echocardiography.
No takes yet. Share an insight, caveat, or question.
May aid symptom risk stratification via exercise echocardiography in asymptomatic degenerative mitral regurgitation; leaves open prospective validation before guiding intervention.
Magné et al. (2010) studied this question.
