Identification of Genetic Markers for Cardiopulmonary Diseases (Genotype) — Genotype  

Cardiovascular Diseases Clinical Trial

Official title: Identification of Genetic Markers for Cardiopulmonary Diseases

Status Completed

Clinical Trial Summary

This study is designed to investigate whether an association exists between certain genes/protein levels and the development of various cardiopulmonary diseases. It is hoped that this project will provide valuable insight into the understanding of these diseases.

Clinical Trial Description

There are two main groups of participants in this trial:

Group 1: Patients that are enrolled in either or both of previous studies: X980515002 study (Identification of Genetic Markers for Primary Pulmonary Hypertension) and or X030403017 study (Pulmonary Arterial Hypertension (PAH) Database)

Group 2: Participants with the diagnosis of any of the previously listed Cardiopulmonary Diseases who are ≥15 years of age

Group 1: For those patients who have had blood samples drawn as a result of participating in the current protocol, Identification of Genetic Markers for Primary Pulmonary Hypertension study (X980515002), we would like to use their previously obtained blood and continue to draw samples (12mL; less than 3 tablespoons) ONLY if they change disease therapies. With each disease therapy change, blood will be drawn at baseline, at 3-4 month, at 6-8 month, at 12 month, and at 24 month visits. These current X980515002 participants WILL sign a consent form to participate in this new trial. As for the X980515002 expired patients, we would like to use the previously obtained data ONLY in part for this study that was collected as a result of the X980515002 study.

For those patients who participated in Pulmonary Arterial Hypertension (PAH) Database study (X030403017), these participants WILL also sign a consent form to participant in this new trial. We would like to use the previously obtained data from the X030403017 in part with this study. With each disease therapy change, a 12mL (less than 3 teaspoons) blood sample will be drawn at baseline, at 3-4 month, at 6-8 month, at 12 month, and at 24 month visits. As for the X030403017 expired patients, we would like to use the previously obtained data in part for this study that was collected as a result of the X030403017 study.

Group 2: After signing a consent form, these participants will have a 12mL (less than 3 teaspoons) blood sample drawn at baseline, at 3-4 month, at 6-8 month, at 12 month, and at 24 month visits. With each disease therapy change, the blood draws (12mL samples) will begin again at baseline and continue through the 3-4, 6-8, 12, and 24 month visits. ;
