Achtergrond van het onderzoek
Pulmonary arterial hypertension (PAH) is a progressive disease with a mean 4-year survival rate of 50-60%. Due to an increase in pulmonary arterial resistance the right ventricle needs to adapt to the increased workload. Often this results in dilatation of the right ventricle en eventually in right sided heart failure. Nowadays right heart catheterization is used tot diagnose PAH, by measuring the pressure and volume changes over time a pressure-volume loop is created. This loop provides functional information of the right ventricle. Unfortunately right heart catheterization is an invasive procedure associated with certain risks.
A recently developed analysis technique based on echocardiographic assessments provides information about the functional information of the ventricles. This data can be used to reconstruct surrogate pressure-volume loop. Continues registration of this loop can be used to provide information of the right ventricle in a non-invasive way.
A combination of these analyzed surrogate pressure volume loops with data from patient files and municipal population register will be used in an attempt to predict mortality and morbidity in patients with pulmonary arterial hypertension.
Doel van het onderzoek
Objective: The overall aim of this project is to asses the prognostic value of the characteristics of an echocardiographic surrogate pressure-volume loop on mortality and morbidity due to PAH.
Onderzoeksopzet
Echocardiographic assessments after diagnosis of PAH will be used as baseline time point to analyze the characteristics of the surrogate pressure-volume loop. Registration of morbidity and mortality events will be used as time points to determine the prognostic value of these characteristics.
Onderzoeksproduct en/of interventie
A questionnaire regarding physical health, hospital or general practitioner visits and change in treatment will be send annually.
