Current Status and Effect of Outpatient Cardiac Rehabilitation After Percutaneous Coronary Intervention in Japan

Abstract

very little evidence has been published regarding CR participation rates and the effect of CR on mortality after PCI. The aims of this study were to describe the current participation rates of CR after PCI in ACS and sCAD patients and to investigate the effects of outpatient CR after PCI on the mortality rate using a nationwide administrative database in Japan. Methods Data Source Data were extracted from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) between April 2013 and March 2019; data were C ardiac rehabilitation (CR) is an evidence-based intervention associated with a reduction in mortality and rehospitalization, as well as improved quality of life, in patients with coronary artery disease (CAD), including both acute coronary syndrome (ACS) and stable CAD (sCAD). 1-3 Current guidelines in Japan show that CR is strongly recommended after myocardial infarction and percutaneous coronary intervention (PCI). 4 However, the rate of CR participation is low worldwide, especially in Japan. 5,6 Previous surveys demonstrated that the rates of participation in CR for ACS in Japan were lower than in the US, UK, and France. 7,8 A recent Japanese survey (i.e., Japanese Registry Of All cardiac and vascular Diseases [JROAD]) showed that the overall number of patients receiving CR is gradually increasing in Japan, 9 but

A nationwide survey on participation in cardiac rehabilitation among patients with coronary heart disease using health claims data in Japan

“…In addition, while previous studies in North America reported that men are more likely to participate in CR than women, the present study found no difference between men and women. This finding, however, is consistent with the results of previous studies in Japan 25 , 39 – 41 . We also found that patients who underwent CABG were more likely to participate in CR than those who underwent PCI, consistent with a previous report 25 .…”

Outpatient cardiac rehabilitation dose after acute coronary syndrome in a nationwide cohort

“…The global participation rate for CR following myocardial infarction is less than 30% 13 14. There are regional differences in the proportion of CR participation rates worldwide and in Japan, which suggests that the number of hospitals approved to provide CR and the medical staff may be insufficient to provide adequate CR; strategies to increase the number of CR are required 15 16…”

Contemporary use of SGLT2 inhibitors in heart failure patients with diabetes mellitus: a comparison of DPP4 inhibitors in a nationwide electric health database of the superaged society

“…It includes claims on inpatient and outpatient services and prescriptions. Japan has a universal health coverage system, and the NDB covers approximately 98% of data on health care services provided by health care institutions, regardless of the type of insurance [ 12 , 13 ]. The NDB includes two anonymized types of personal identification variables (ID1 and ID2) and the group of Nara Medical University has constructed a new patient-matching variable (ID0) with ID1 and ID2, which allows each patient to be followed up longitudinally using an individual claims data system in the NDB database [ 14 ].…”
