Description

Device and method for providing customized cardiac rehabilitation content

The present invention relates to a technology for providing customized cardiac rehabilitation content, and more specifically, to a device and method for providing customized cardiac rehabilitation content that can recognize and periodically manage the risk of recurrence in advance by providing specialized cardiac rehabilitation services to patients with heart disease. It's about.

It is recommended that patients with cardiovascular disease need a total of 36 cardiac rehabilitation sessions over 3 months to manage their prognosis. Cardiac rehabilitation prevents recurrence and complications through multifaceted education on nutrition, risk factor control, and improvement of medication compliance, including exercises to strengthen the heart muscle and cardiopulmonary endurance of patients with heart and vascular diseases such as angina, myocardial infarction, and heart failure. However, the participation rate is low.

Looking at the current status of cardiac rehabilitation in Korea, only 47 of the 164 hospitals performing percutaneous coronary intervention (PCI) nationwide are performing cardiac rehabilitation. Hospitals that perform cardiac rehabilitation are concentrated in the metropolitan area or large cities. In addition, the participation rate in hospital-based cardiac rehabilitation is low compared to the international average of 15-30%, but in Korea, the rate of receiving at least one type of cardiac rehabilitation-related education, evaluation, or treatment between 2017 and 2019 was 11%, which is significantly lower than the international average.

To improve low participation rates, a shift from traditional hospital-based to home-based cardiac rehabilitation has been proposed. Attempts are also being made to introduce smartphones, wearable devices, and digital therapeutics to effectively implement home-based cardiac rehabilitation.

In addition, digitalization is being promoted rapidly in the health market as demand for non-face-to-face services increases due to the COVID-19 pandemic. As the mobile health (mHealth) field is rapidly expanding among digital health, there is a need for digital care services for patients who have difficulty receiving cardiac rehabilitation.
