研究室紹介
Professor Eue Keun Choi's research lab specializes in cardiovascular and clinical epidemiology, focusing on real-world evidence from national health databases and advanced cardiac electrophysiology. The lab investigates the impact of systemic conditions—such as cancer, oral health, and atrial fibrillation—on cardiovascular outcomes, with a strong emphasis on population-level trends, risk prediction, and the development of AI-driven diagnostic tools for arrhythmias. Key research directions include leveraging claims data for health services research, understanding autonomic nervous system influences on cardiac arrhythmias, and applying deep learning to improve atrial fibrillation detection from wearable device data.

15The Korean National Health Information Database (NHID) contains nationwide claims data, including sociodemographic data, health care utilization, health screening data, and healthcare provider information. To compensate for the limitations of randomized clinical trials, real-world observational studies using claims data have emerged as a novel research tool. We summarized the structure of the Korean NHID and the recent researches conducted in the field of cardiovascular science. Epidemiological
BACKGROUND: Little is known about the relationship between intrinsic cardiac nerve activity (ICNA) and spontaneous arrhythmias in ambulatory animals. METHODS AND RESULTS: We implanted radiotransmitters to record extrinsic cardiac nerve activity (ECNA; including stellate ganglion nerve activity and vagal nerve activity) and ICNA (including superior left ganglionated plexi nerve activity and ligament of Marshall nerve activity) in 6 ambulatory dogs. Intermittent rapid left atrial pacing was perfor
Patients with atrial fibrillation had a 4 times increased risk of mortality compared with the general population. However, the impact of atrial fibrillation on mortality decreased with age and in men. Cerebral infarction was the most common cause of death, and more attention should be paid to reducing the risk of stroke.
We investigated whether oral health, represented by missing teeth, was associated with an increased risk of cardiovascular disease, including myocardial infarction (MI), heart failure (HF), stroke, and all-cause mortality. Subjects who underwent routine dental examinations and health checkups provided by the Korean National Health Insurance from 2007 to 2008 ( n = 4,440,970) were followed up for incident MI, HF, stroke, and death until 2016. During follow-up of 7.56 y, 68,063 (1.5%) subjects die
Although patients with cancer were found to have a higher risk of AF, the impact on AF development varied by cancer type.
BACKGROUND: Wearable devices have evolved as screening tools for atrial fibrillation (AF). A photoplethysmographic (PPG) AF detection algorithm was developed and applied to a convenient smartphone-based device with good accuracy. However, patients with paroxysmal AF frequently exhibit premature atrial complexes (PACs), which result in poor unmanned AF detection, mainly because of rule-based or handcrafted machine learning techniques that are limited in terms of diagnostic accuracy and reliabilit
Between 2008 and 2015, a greater proportion of AF patients received OAC treatment with increasing NOAC prescription trends in the recent 3 years. A substantial proportion (approx. 50%) of Korean patients with AF still remain undertreated.
