Korea Acute Myocardial Infarction Registry

This multicentre observational registry study, the Korea Acute Myocardial Infarction Registry (KAMIR-7), aims to improve long-term prognosis in Korean patients with acute myocardial infarction (AMI) by establishing and operating a nationwide patient registry system. Participating hospitals across Korea, treating AMI patients, will contribute prospective clinical and health-related data. The registry system is web-based and designed to support various clinical and epidemiologic research initiatives, provide standardized data, and facilitate collaborative studies, including participation in international studies such as GRACE.

The primary objectives are:

1. To establish and maintain a sustainable nationwide AMI patient registry to enable continuous collection of high-quality clinical data. 2. To develop a Korean-specific AMI prognostic model by evaluating the applicability and discriminative power of existing foreign risk prediction models (e.g., GRACE score, TIMI score, PERSUIT model, ACTION score) using domestic patient data. 3. To identify clinical and management factors significantly affecting AMI outcomes and model mortality risk using accessible clinical and initial presentation data, including total ischemic time (symptom-to-hospital and door-to-balloon time). 4. To develop clinical and quality indicators to evaluate appropriateness of care and emergency management systems, incorporating patient transport, pre-hospital management, and hospital treatment timeliness.

Secondary objectives include:

* To ensure sustainable patient enrollment and prospective follow-up systems that can support clinical and public health research. * To create a resource for future research on new antiplatelet agents, stents, or interventional strategies. * To provide data for nested case-control studies within the cohort, facilitating research on clinical characteristics, treatment courses, and outcomes in AMI patients. * To identify new prognostic factors influencing patient outcomes and establish guidelines appropriate for Korean clinical practice. * To address limitations of prior KAMIR studies, including short follow-up duration and limited heart failure-related data, and incorporate evolving treatment strategies, devices, and medications.

Through systematic data collection and networked collaboration, this study will enable comprehensive analyses of long-term outcomes in Korean AMI patients, contribute to evidence-based optimization of treatment strategies, support development of prognostic tools specific to the Korean population, and inform health policy and clinical guideline refinement. The registry will also foster research collaboration among hospitals, investigators, and international study networks to advance the understanding and management of AMI in Korea.
