A nUtrition and Lifestyle Intervention in Patients With Pulmonary Arterial HypertensIon (UPHILL)
A nUtrition and Lifestyle Intervention in Patients With Pulmonary Arterial HypertensIon: Effect on quaLity of Life
Rationale: Nutrition and lifestyle interventions are currently not implemented in usual clinical care of PAH-patients. Mainly because there is little known on the relation between pathology, nutrition and lifestyle. Patients who suffer from Pulmonary Arterial Hypertension feel insecure about their nutrition and lifestyle. The investigators hypothesize that an intervention on nutrition and lifestyle can improve the patients' quality of life.
Objective: To explore the effect of a nutrition and lifestyle intervention on quality of life for patients suffering from PAH.
Study design: Investigator initiated intervention study with control group. Study population: investigators aim to include 70 patients (18 - 80 years) with idiopathic, hereditable or drug related PAH, who have been stable for at least three months and are self-sufficient and/or have a family who's willing to participate in the lifestyle changes.
Intervention (if applicable): Nutritional status, - education, - intervention and - compliance.
Main study parameters/endpoints: This is an intervention study in which the investigators will asses the effect of a nutrition and lifestyle intervention on quality of life measured by SF-36 overall outcome with a significant difference of 6.35.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The burden for the patient exists of 12 extra visits to the hospital and contact moments, over a period of 11 months, as well compliance to the diet and lifestyle. There is minimal risk in participation.
