Key result
High-intensity interval training improved peak oxygen consumption and 6-minute walk distance without serious cardiovascular complications in two patients with chemotherapy-related cardiomyopathy.
Why the study?
Studies on the efficacy and safety of cardiac rehabilitation in patients with chemotherapy-related cardiomyopathy are lacking.
Does high-intensity interval training improve exercise capacity in patients with chemotherapy-related cardiomyopathy?

Does high-intensity interval training improve exercise capacity in patients with chemotherapy-related cardiomyopathy?
High-intensity interval training may safely improve aerobic exercise capacity in patients with chemotherapy-related cardiomyopathy.
May support HIIT feasibility in chemotherapy-related cardiomyopathy; leaves open need for randomized trials.
Studies suggest that exercise regimens are beneficial across all phases of cancer treatment and rehabilitation. However, studies on the efficacy and safety of cardiac rehabilitation in patients with chemotherapy-related cardiomyopathy are lacking. Herein, we present two patients diagnosed with chemotherapy-related cardiomyopathy who participated in a cardiac rehabilitation program, including eight weeks of high-intensity interval training, and their exercise capacity was monitored. Both patients showed significant increases in peak oxygen consumption and 6-min walk distance. High-intensity interval training results in objective improvements in aerobic exercise capacity without serious cardiovascular complications in patients with chemotherapy-related cardiomyopathy.

Choi et al. (2022) conducted a case report in Chemotherapy-related cardiomyopathy (n=2). High-intensity interval training was evaluated on Peak oxygen consumption and 6-min walk distance. High-intensity interval training improved peak oxygen consumption and 6-minute walk distance without serious cardiovascular complications in two patients with chemotherapy-related cardiomyopathy.
