Key result
Between 2009 and 2016, the annual new implantation rates of pacemakers, ICDs, and CRT devices in South Korea increased from 5.1 to 9.3, 0.6 to 1.9, and 0.1 to 0.5 per 100,000 persons, respectively.
Why the study?
Implantation of cardiac implantable electronic devices has increased significantly, but limited data exist regarding temporal trends of CIED implantations in the Asian population.
Cohort (n=35,421)
CIED implantations in Korea increased substantially from 2009 to 2016, with recipients becoming older and having more comorbidities, highlighting an expected increase in future healthcare burden.

Increasing CIED implantations signal growing future healthcare burden; leaves open optimal resource allocation and outcome data in older, comorbid patients.
BACKGROUND AND OBJECTIVES: Implantation of cardiac implantable electronic devices (CIED), including permanent pacemakers (PM), implantable cardioverter-defibrillators (ICD), and cardiac resynchronization therapy (CRT) devices, has increased significantly over the past several years. However, limited data exists regarding temporal trends of CIED implantations in Asian population. This study aimed to investigate temporal trends of CIED treatment in Korea. METHODS: Using the National Health Insurance Service database of the entire Korean adult population, temporal trends of CIED procedures between 2009 and 2016 were evaluated. Additionally, temporal changes in the prevalence of patients' comorbidities were evaluated. RESULTS: A total of 35,421 CIED procedures (new implantations: 27,771, replacements: 7,650) were performed during the study period. The mean age of new CIED recipients and the prevalence of comorbidities, including hypertension, diabetes mellitus, heart failure, stroke, and atrial fibrillation, increased substantially with time. Compared to 2009, the number of new implantations of PM, ICD, and CRT devices increased by 2.0 (1,977 to 3,910), 3.6 (230 to 822), and 4.9 (44 to 217) times in 2016, respectively. The annual new implantation rate of CIED also increased accordingly (5.1 to 9.3 for PM, 0.6 to 1.9 for ICD, and 0.1 to 0.5 for CRT devices, per 100,000 persons). CONCLUSIONS: The number of CIED implantation increased substantially from 2009 to 2016 in Korea. Also, the patients with CIED have been changed to be older and have more comorbidities. Therefore, the burden of health care cost in patients with CIED would be expected to increase in the future.

Lee et al. (2019) conducted a cohort in Cardiac implantable electronic device (CIED) implantation (n=35,421). Cardiac implantable electronic device (CIED) implantation was evaluated on Temporal trends of annual new implantation rates of CIEDs per 100,000 persons. Between 2009 and 2016, the annual new implantation rates of pacemakers, ICDs, and CRT devices in South Korea increased from 5.1 to 9.3, 0.6 to 1.9, and 0.1 to 0.5 per 100,000 persons, respectively.
