Coronary artery disease is one of the major causes of morbidity and mortality in industrialized countries, including Japan. Increasing numbers of patients have been treated with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), but there is little information in Japan concerning the use of revascularization therapy and the facilities. The Japanese Coronary Intervention Study (JCIS) Group conducted a nation-wide survey on coronary revascularization procedures and facilities during 1997. A questionnaire was mailed to the presidents or designated delegates of 8,253 laboratories in 7,986 hospitals that had departments of internal medicine and/or cardiovascular medicine and to 578 facilities in 558 hospitals identified by the PCI survey as performing CABG and/or registered in the annual survey carried out by the Japanese Association for Thoracic Surgery. A total of 109,788 PCIs were performed at 1,023 laboratories, and 17,667 CABGs at 477 facilities. PCI and CABG numbers per 106 population were 870 and 140, respectively. The ratio of PCI to CABG was 6.2. The numbers of PCI laboratories and CABG facilities per 106 population were 8.1 and 3.8, respectively. The majority of PCI laboratories and CABG facilities had a small annual volume: 44% of PCI laboratories and 77% of CABG facilities had annual volumes of 50 or less. Only half of the PCI laboratories had surgical backup on-site. Despite the small volume for each facility, coronary revascularization, especially PCI, is highly utilized in Japan.
