Abstract

BACKGROUND AND OBJECTIVES: The development of coronary intervention registry system is required for analysis of current status and more efficient management of patients with coronary artery disease in Korea. We developed database system and registry system in internet environment to confirm the possibility of nationwide system construction and of useful information providing on coronary intervention. MATERIALS AND METHOD: Database for coronary intervention and web-based registry system were developed and installed on internet server. Data elements consist of demographics, coronary risk factors, initial diagnosis, lesion characteristics, type of interventional procedures, and post-procedure outcomes. RESULTS: Total 734 patients were registed by 12 intervention centers from November 1998 to October 1999. Patients with angina pectoris and myocardial infarction were 78.5% and 21.5%, respectively and 14.6% of all patients had history of previous coronary intervention. Major coronary risk factors of the patients were smoking (38.6%), hypertension (33.8%), and diabetes (18.0%). Proportions of the patients with single-vessel disease, two-vessel disease, and triple-vessel disease were 64.7%, 26.2%, and 9.1%, respectively. Left main disease was detected in 2.0%. Balloon PTCA only was performed in 209 patients and 530 patients underwent coronary stent insertion. CONCLUSION: Multicenter data of coronary intervention were collected via internet-based system, and it was possible to construct intervention database. These web-based systems linked with database will provide status of Korean interventional procedures and be able to support multicenter study efficiently by expanding the participating hospitals and including more detailed database fields.
