Page: << Prev | 1 | 2 Compared to the healthy brothers and sisters, the survivors of childhood cancer were almost six times more likely to report congestive heart failure; about five times more likely to report having had a heart attack or valvular heart disease; more than six times likelier to have pericardial disease (the pericardium is the sac that surrounds the heart); more than eight times as likely to have had an angiography; and 10 times more likely to have atherosclerosis, or hardening of the arteries.
Exposure to the chemotherapy drug anthracycline increased the risk of congestive heart failure about fourfold, roughly doubled the risk of pericardial and valvular disease, and almost tripled the odds of having had an angiography, the study found.
Radiation treatment to the heart doubled the risk of congestive heart failure, heart attack and pericardial disease, almost tripled the risk of valvular disease, and increased the risk of atherosclerosis by a factor of more than five, according to the study.

Dr. Karen Burns is clinical director of the ATP5+ Clinic for Childhood Cancer Survivors at Cincinnati Children's Hospital. She said most of the heart problems seen in survivors of childhood cancer come from the class of chemotherapy drugs called anthrocyclines, which cause problems with cardiac muscle, and from radiation, if the radiation field included the heart.
Although monitoring for heart disease in childhood cancer survivors is already in place in many specialized facilities, Burns said she hoped that, "if this study is available to the general public, it will encourage people who are survivors to get closer follow-up."
Mulrooney added: "We see this in our long-term follow-up clinic. We identify patients who are at risk based on this analysis and may do an echocardiogram or a lipid panel, things we might not typically do in a 20-year-old. There are tools out there, and getting this knowledge out there as well would be helpful so primary-care physicians will be more aware, oncologists and cardiologists will be aware, and patients as well."
