Abstract
Background: We previously reported the results of a questionnaire survey of 37 cardiac rehabilitation (CR) training facilities conducted during April 2020, in Japan. Methods and Results: We conducted a second questionnaire survey in 38 CR training facilities to explore the preventive measures against Coronavirus Disease 2019 (COVID-19) after a nationwide state of emergency was declared and to investigate differences between the 2 surveys. No significant differences were observed, except for the requirement for patients to wear surgical masks during CR (P=0.01) in the second survey. Thirty-four facilities (89%) continued CR with innovations, 61% revised their instruction manuals (vs. 46% in the first survey), and, in 39%, patients requested resumption of ambulatory CR and training videos. Conclusions: In the second survey, 74% of facilities were unable to continue conventional group ambulatory CR; however, patients maintained their physical activity and exercise regimens and managed their illnesses with the aid of telephones and mobile devices.
