Exercise testing and cardiac rehabilitation in patients treated for cancer.

Cardiovascular disease (CVD) is a major competing cause of morbidity and mortality in patients with cancer. Cancer treatment can have detrimental short- and long-term cardiovascular effects. Moreover, cancer patients may have a significant loss in cardiorespiratory fitness, a key CVD risk factor, during and after cancer treatment. Exercise training has emerged as a potential intervention to improve fitness and reduce the risk of CVD in cancer. In this review, we discuss the role of cardiorespiratory fitness to predict cancer and CVD outcomes, as well as explore the impact of exercise training to improve fitness and other key outcomes in patients with cancer. The role of cardio-oncology rehabilitation will also be highlighted.
