The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.

Individuals are being asked to volunteer for a research study. Research studies are voluntary and include only those who choose to take part. The purpose of this research study is to compile a repository of participants who are willing to participate in rehabilitation research studies.

Participants will complete a datasheet that includes contact information and basic medical conditions. Once the datasheet is complete, participants will then await contact from VA Investigators. The study will continue until the participant decides they no longer wish to participate or becomes deceased.

There will be no direct benefit to participants from taking part in this study. The risk associated with this study is a potential loss of confidentiality.
