简要总结
The purpose of this study is to determine the prognostic value of echocardiographic parameters in comparison with clinical and hemodynamic parameters in pulmonary arterial hypertension (PAH).
A secondary purpose of this study is to analyze the disease evolution after 3 to 6 months. In pulmonary fibrosis it has been demonstrated that the variation of clinical and paraclinical parameters between 2 examinations has a prognostic interest. In this study the prognostic value of variation of some echocardiographic parameters between initial examination and echocardiography after 3 or 6 months will be evaluated.
Another secondary purpose is to create a common database for Pneumology, Cardiology and Epidemiology departments with prospective registration of new cases of PAH and follow of patients under treatment.
详细描述
Pulmonary arterial hypertension (PAH) is a rare pathology with a poor prognosis and a median survival lower than 3 years in the absence of a specific treatment.
The prognostic evaluation is based on clinical and hemodynamic data needing the right cardiac catheterization. It has been shown that prognosis depends essentially on the severity of right ventricular dysfunction. Recently, various echocardiographic parameters derived from new techniques such as tissue Doppler have been validated for the evaluation of right ventricular function. Some have been used as prognostic factor in cardiac insufficiency, but not in PAH.
This is an observational retrospective and then prospective study. Usual PAH assessment includes a complete clinical and paraclinical evaluation. History and physical examination assess dyspnea, search signs of disease severity and quantify functional impact of 6 min-walking test. An echocardiography and a right cardiac catheterization are realized in all patients. Clinical consultations of patients and control echocardiographic and hemodynamic examinations are programmed at regular intervals.
The demonstration of prognostic value of some echocardiographic parameters could diminish right cardiac catheterizations.
