Cardiac Function and Exercise Capacity in Pulmonary Arterial Hypertension
Cardiac Function and Exercise Capacity in Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension is characterized by a progressive increase in pulmonary
 vascular resistance inducing shortness of breath and exercise intolerance. We aim to
 correlate cardiac function (evaluated at rest by right heart catheterism and RMN) to exercise
 capacity (evaluated by endurance time at 75% of maximal workout), in prevalent patients with
 pulmonary arterial hypertension, and their evolution at three and twelve months.
Inclusion Criteria:

 -  Adult patients

 -  Patients with Pulmonary Arterial Hypertension (idiopathic, heritable or due to
 anorexigens),

 -  Prevalent cases of pulmonary artery hypertension (≥ 6 months) confirmed by right heart
 catheterism,

 -  Stable for at least 3 months,

 -  Written consent.

 Exclusion Criteria:

 -  Patients unable to proceed with six-minute walk test or CPET, or with
 contra-indication to exercise evaluation (syncope, low cardiac index, etc).

 -  Exercise induced abnormality (evaluated during the initial CPET) precluding to further
 evaluation.
