Cardiac rehabilitation has been proven to be effective in treating heart disease patients, but in Japan, the participation rate in outpatient cardiac rehabilitation is low at around 4-8%, resulting in many heart disease patients being repeatedly re-admitted to hospital, which places a burden on society as a whole in terms of medical expenses. By providing appropriate exercise therapy and behavioral modification to a variety of patients, including those with heart disease, CaTe aims to create an environment where many patients can receive better medical care at home, creating a healthier future.
