Clinical Trial Summary

The RECONNECTIVE Registry is an observational single center study, focused on the subgroup of precapillary pulmonary hypertension related to connective tissue diseases. All patients will have hemodynamic confirmation by right heart catheterization and will be follow-up for at least 5 years from admission. All patients diagnosed with Group I Pulmonary Arterial Hypertension (PAH) associated with Connective Tissue Diseases (CTD) and Group IV Pulmonary Hypertension (PH) with CTD will be included. The purpose of the registry is to learn and understand the clinical outcomes and natural history of the pulmonary arterial hypertension in this subgroup of patients to improve the medical care and treatment.

Description:

Connective tissue diseases represents an important risk factor for pulmonary hypertension, either due to vasculopathy or chronic pulmonary thromboembolism. These chronic conditions are characterized by being disabling, progressive and fatal in a short time and are caused by multiple mechanisms that results in remodeling of the pulmonary microvasculature and right heart failure. In recent years, due to international registries, we have acquired a better understanding of high-risk subpopulations, their poor prognostic factors, and the results of specific combination therapies. In Mexico, the National Institute of Medical Sciences and Nutrition Salvador Zubirán (INCMNSZ) is a referral center for connective tissue diseases and pathologies of the pulmonary circulation. The RECONNECTIVE registry is a five years follow-up cohort that offers the possibility to obtain data regarding to the clinical characteristics and hemodynamic assesment of pulmonary circulation. The main objective is to evaluate the clinical course of the PAH in this subgroup of patients and their specific therapy for PAH.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To characterize the clinical clinical course of Pulmonary Arterial Hypertension (PAH) associated with Connective Tissue Diseases (CTD) in a register of Mexican patients from the first visit and at every 6 months.	Outcome measure: Clinical worsening: defined internationally by death, lung or heart-lung transplantation, atrial septostomy, hospitalization due to worsening PAH, initiation of new PAH approved therapy, or worsening WHO functional class.	5 years
Secondary	World Health Organization functional class (I-IV)	Assesment of the functional class according to the World Health Organization (WHO) functional class (in scale from I-IV) in each scheduled visit (every 3 to 6 months) in the pulmonary hypertension clinic. It will help as part of the multiparametric variables to determine the comprehensive risk assessment (estimated 1-year mortality)	5 years
Secondary	Assesment of the right ventricular function by echocardiogram (TAPSE, Right atrial area and pericardial effusion)	Assesment of the right ventricular function by echocardiogram performed by an expert in echocardiography in each scheduled visit (every 6 to 12 months) in the pulmonary hypertension clinic. It will help as part of the multiparametric variables to determine the comprehensive risk assessment (estimated 1-year mortality)	5 years
Secondary	Concentration of serum brain natriuretic peptide	Concentration of serum brain natriuretic peptide in each scheduled visit (every 3 to 6 months) in the pulmonary hypertension clinic. It will help as part of the multiparametric variables to determine the comprehensive risk assessment (estimated 1-year mortality)	5 years
