Impact of breast cancer on in-hospital mortality and health care utilization in female heart failure patients: a retrospective cohort study.

Breast cancer significantly increases the in-hospital mortality risk and length of hospital stay in patients with HF. These findings highlight the need for integrated cardiovascular and oncological care, especially in the presence of metastatic breast cancer. The study underscores the importance of tailored management strategies for patients with HF with concurrent breast cancer and points toward the necessity for addressing racial disparities in health care.
