Patients with a history of breast cancer or lymphoma may be more than three times as likely to develop heart failure (HF), according to research that will be presented at ACC.18 in Orlando. Carolyn Larsen, MD, et al., tracked HF cases in 900 breast cancer and lymphoma patients and in 1,550 people without cancer from 1985 to 2010. Results showed that for every 100 cancer patients, about seven developed HF during the 8.5-year follow-up period. Patients with breast cancer or lymphoma were three times as likely to develop HF within five years of their cancer diagnosis. In addition, the cancer patients were nearly twice as likely to have a HF diagnosis 20 years after undergoing cancer treatment compared with patients who never had cancer. Read more.
