Multi-Center, Prospective, Nation-Wide Coronary Angioplasty Registry in Thailand (Thai PCI Registry): Registry Design and Rationale

Background: Coronary artery disease (CAD) is one of the most common causes of death worldwide. Percutaneous coronary intervention (PCI) is currently the main revascularization modality for these patients. The practice of PCI, outcomes and resource utilization varies in many parts of the world. Therefore, it is important to have local information regarding the patient demographics, pattern of PCI practice, and outcomes.

Objective: To report the study design, protocol and rationale of the Thai PCI registry.

Materials and Methods: Thai PCI Registry is a prospective, multi-center study which is an initiative project of the Cardiac Intervention Association of Thailand (CIAT). The study consisted of phase I for cross-sectional data registry and phase II for follow up study. The project was started in November 2015. All catheterization laboratories in Thailand were invited to participate in this nationwide registry. The details regarding patient characteristics, procedural details, equipment, and outcomes of PCI were prospectively collected using well-constructed case record form. The protocol of the registry has been approved by the Central Research Ethics Committee (CREC). The project received a research grant from the Health System Research Institute, The Ministry of Public Health, in Thailand, March 2017.

Results: There were 39 hospitals from all areas of the country participated in the registration. The hospital type and size were varied and well represented of the PCI centers in Thailand. The registry planned to enroll all consecutive PCI patients at each hospital for approximately one year with the estimated number of PCI at 22,000 procedures. Initially, all patients were followed up for at least 6 and 12 months.

Conclusion: The present study provides rationale, protocol, definition and study design of Thai PCI registry. The results of the Thai PCI registry would yield the essential information regarding the current real-world practice as well as the results and complications of PCI.
