Pulmonary Arterial Hypertension Clinical Trial

Official title: Redefining Pulmonary Hypertension Through Pulmonary Vascular Disease Phenomics (PVDOMICS)

Status Active, not recruiting

Clinical Trial Summary

It is recognized that patients with various forms of heart and lung disease exhibit varying degrees of pulmonary hypertension, pulmonary vascular remodeling, and right ventricular dysfunction. The genetic, molecular, and cellular processes driving these phenomena are not well understood. Rapid advances in high throughput omic methodology, combined with powerful bioinformatics and network biology capability, have created the opportunity to conduct studies that broadly search for homologies and differences across the spectrum of disease states associated with pulmonary hypertension, and determinants of the spectrum of right ventricular compensation that accompanies these conditions

Clinical Trial Description

The protocol is designed to lead to new understanding of patients with pulmonary hypertension and right heart dysfunction, based on molecular, clinical, hemodynamic and radiographic characteristics. New classifications will be a product of association of these in depth phenotypic descriptions with specific molecular mechanisms of pathogenesis. The protocol will be implemented to lead to identification of both sub-phenotypes of lung vascular disease and to biomarkers of disease that may be useful for early diagnosis or for assessment of interventions to prevent or treat this condition.

A longitudinal study in a subset of the participants enrolled in the parent cross-sectional study will:

1. Retest participants at a minimum 6 month interval from initial evaluation to collect a core set of clinical and OMICS features. This will include survival, clinical staging, clinical group assignment, 6-minute walk, echocardiography, and blood for a broad collection of selected OMICS tests, to include proteomics and other variables found to be informative in the initial set.

2. Associate and compare OMICS data with clinical sets and OMICS clusters between baseline and follow-up interval, with attention to reproducibility, predictive capacity as biomarkers for diagnosis, disease progression, phenotypic changes, functional capacity, therapeutic response and survival. ;
