Brief Summary
We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

Outcome Measures
Primary Outcomes (1)
Development of cardiomyopathy
Decrease in fractional shortening below normal (\<28%)
Within 5 years after receiving anthracyclines.
Eligibility Criteria
Patients exposed to anthracycline who have had an echocardiogram at least six months after initial exposure.
You may qualify if:
- ) Echocardiogram at least six months after exposure to anthracyclines (in patients over the age of 40, the echocardiogram must be obtained within 6 - 48 months of anthracycline exposure)
- ) Ability to understand and the willingness to sign a written informed consent document.
- We have no age, gender, or ethnic background limitations. Due to the increased frequency of cardiovascular disease from other causes in adults over 40 years, we will limit enrollment to those patients with an echocardiogram 6 - 48 months after the completion of anthracycline exposure. Children will be included and will be eligible if they have an echocardiogram at least 6 months after completion of anthracycline treatment..
You may not qualify if:
- ) Pre-existing cardiomyopathy before anthracycline administration
- ) Patients with Down syndrome
- ) Patients receiving B-blocker therapy at the time of anthracycline exposure
- ) Pregnant patients (if their echocardiogram was obtained either during pregnancy or within three months of pregnancy)
- All participants will be cancer survivors. To minimize bias from post-partum cardiomyopathy, pregnant patients will be excluded if their echocardiogram was obtained during pregnancy or within three months of pregnancy. HIV-positive persons will not be excluded from the study.
- Of note, some patients receive a MUGA (multigated acquisition) study to evaluate left ventricular ejection fraction. Patients who receive only a MUGA scan will NOT be included in the study - an echocardiogram is necessary
