What this trial studies

The RECONNECTIVE Registry is an observational study that focuses on patients with precapillary pulmonary hypertension associated with connective tissue diseases. It aims to gather data on clinical outcomes and the natural history of this condition over a five-year follow-up period. Patients will undergo hemodynamic confirmation through right heart catheterization to ensure accurate diagnosis and monitoring. The registry seeks to improve medical care and treatment strategies for this specific subgroup of patients.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with Group I or Group IV pulmonary arterial hypertension associated with connective tissue diseases.

Not a fit: Patients with pulmonary hypertension classified under Groups II, III, or V will not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could enhance understanding and management of pulmonary arterial hypertension in patients with connective tissue diseases, leading to better treatment outcomes.

How similar studies have performed: Other international registries have shown success in understanding high-risk subpopulations and their treatment outcomes, indicating that this approach is supported by prior research.
