The purpose of this research is to collect blood and tissue for DNA and biomarkers and store for future analysis. This will be done in patients predisposed to cardiomyopathy and congestive heart failure, and its complications, i.e., sudden cardiac death, pump failure and ventricular arrhythmia. There are currently no known genetic markers which predispose to congestive heart failure. The samples will be stored for future use in analysis of molecular, cellular and biological characteristics approved by the IRB. A database of these samples will be developed and samples will be coded in laboratory and storage and only through specific access code, samples will be linked to specific patients. This will be done to maintain patient confidentiality. Additional protocols are to be submitted to the IRB committee in future analysis of stored tissue/DNA/serum stored and used in the future.
Primary Outcome Measures:
- To collect and store blood and tissue from patients who have a diagnosis of heart disease and may be at a high risk for the development of heart failure. [ Time Frame: 7 Years ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples With DNA
Biospecimen Description:
Blood and tissue collection. This blood may be studied in the future to try to find possible genetic or biochemical markers that may be the cause of CHF.

Patients diagnosed with heart disease and that may be at a high risk for the development of heart failure.

Procedure: Blood Sample
One time blood draw of 2 teaspoons.
|
You will have a one time blood draw of 2 teaspoons of blood for use in future research. This blood may be studied in the future to try to find possible genetic or biochemical markers that may be the cause of CHF. Your blood will be drawn either on an outpatient basis or during a routine visit to the hospital. If you already have a central line or an IV placed, the blood will be drawn at these sites to decrease the pain and discomfort of the blood draw. The information obtained in this study will not be put into your medical records.
This is an investigational study. All will be enrolled at M. D. Anderson.
