About the Lab

Professor Cheol Han's research lab specializes in emergency medicine and critical care, with a strong focus on improving outcomes in acute cardiovascular and neurological emergencies. The lab investigates advanced imaging techniques—such as diffusion-weighted MRI—for early prediction of neurological outcomes after cardiac arrest, and explores the clinical utility of artificial intelligence in electrocardiography for rapid diagnosis of acute myocardial infarction. Additionally, the lab examines trauma patterns and risk factors for severe injury in older adults, particularly from outdoor falls, and contributes to emergency preparedness during public health crises like the COVID-19 pandemic.

Recently, the number of Corona Virus Disease 2019 (COVID-19) cases has increased remarkably in South Korea, so the triage clinics and emergency departments (ED) are expected to be overcrowded with patients with presumed infection. As of March 21st, there was a total of 8,799 confirmed cases of COVID-19 and 102 related deaths in South Korea that was one of the top countries with high incidence rates [1]. This sharp increase in infection is associated with 1) outbreaks in individual provinces, 2)

SJR Q1European Heart JournalOA

BACKGROUND AND AIMS: Emerging evidence supports artificial intelligence-enhanced electrocardiogram (AI-ECG) for detecting acute myocardial infarction (AMI), but real-world validation is needed. The aim of this study was to evaluate the performance of AI-ECG in detecting AMI in the emergency department (ED). METHODS: The Rule-Out acute Myocardial Infarction using Artificial intelligence Electrocardiogram analysis (ROMIAE) study is a prospective cohort study conducted in the Republic of Korea from

AIM: The aim of the present study was to evaluate the clinical characteristics, including floor characteristics and factors, related to severe injury from outdoor falls in older adults. METHODS: Patients were divided into two groups based on injury severity: the severe group and non-severe group. The clinical and general characteristics were compared between the two groups, and factors associated with severe injury were investigated. RESULTS: Approximately 5% (364/7635) of older people involved

Heart rate and diastolic arterial pressure in cardiac arrest patients: A nationwide, multicenter prospective registry
Chul Han, Jae Hoon Lee, on behalf of the Korean Hypothermia Network Investigators
SJR Q1PLoS ONEOA

BACKGROUND: Guidelines have recommended monitoring mean arterial pressure (MAP) and systolic arterial pressure (SAP) in cardiac arrest patients, but there has been relatively little regard for diastolic arterial pressure (DAP) and heart rate (HR). We aimed to determine the prognostic significance of hemodynamic parameters at all time points during targeted temperature management (TTM). METHODS: We reviewed the SAP, DAP, MAP, and HR data in out-of-hospital cardiac arrest (OHCA) survivors from the

Background: Falls from low-height can cause severe injuries in the elderly population. This study was conducted to determine characteristics of injuries from low-height falls. Methods: We retrospectively review surveillance data on injured patients who presented to six emergency departments from January 2011 to December 2015. Study subjects were divided into severe group and non-severe group based on severity of injury. The general and clinical characteristics were compared between the two group

Effect of hypertonic saline and macrophage migration inhibitory factor in restoration of T cell dysfunction
윤영훈, 최성혁, 홍윤식, 이성우, 문성우, 조한진, 한철, 전영진, Vishal Bansal

Purpose: Trauma-induced suppression of cellular immune function likely contributes to sepsis, multiple organ dysfunction syndrome and death. T cell proliferation decreases after traumatic stress. The addition of prostaglandin E_2 (PGE_2), which depresses immune function after hemorrhage and trauma, to T-cells decreases T-cell proliferation; and hypertonic saline restores PGE_2-induced T-cell suppression. Recently, it has become apparent that macrophage migration inhibitory factor (MIF) plays a c
