BACKGROUND: Rapid revascularization is the key to better patient outcomes in ST-elevation myocardial infarction (STEMI). Direct activation of cardiac catheterization laboratory (CCL) using artificial intelligence (AI) interpretation of initial electrocardiography (ECG) might help reduce door-to-balloon (D2B) time. To prove that this approach is feasible and beneficial, we assessed the non-inferiority of such a process over conventional evaluation and estimated its clinical benefits, including a

OBJECTIVES: The quality of life after extracorporeal membrane oxygenation therapy has emerged as an important issue for extracorporeal membrane oxygenation survival; however, its association with long-term prognosis has not been identified. We investigated the changes in the quality of life after extracorporeal membrane oxygenation among the survivors and examine the association between a worse quality of life and 3-year all-cause mortality. DESIGN: This was a population-based cohort study. SETT

Background: High C-reactive protein (CRP) levels are associated with poor outcomes of heart failure (HF), and statins are known to reduce CRP levels. We investigated the prognostic value of CRP and statin in patients with HF with reduced and preserved ejection fraction (EF). Methods: Altogether, 3,831 patients from the Korean Acute Heart Failure registry were included and stratified according to the tertiles of CRP levels (T1: CRP < 0.30 mg/dL, T2: 0.30-1.14 mg/dL, and T3: CRP > 1.14 mg/dL). HF

BACKGROUND: Quality of life following extracorporeal membrane oxygenation (ECMO) therapy is an important health issue. We aimed to describe the characteristics of patients who developed chronic respiratory disease (CRD) following ECMO therapy, and investigate the association between newly diagnosed post-ECMO CRDs and 5-year all-cause mortality among ECMO survivors. METHODS: We analyzed data from the National Health Insurance Service in South Korea. All adult patients who underwent ECMO therapy i

INTRODUCTION: This study aimed to investigate trends in extracorporeal membrane oxygenation (ECMO) treatment during 2005-2018 and examine factors associated with in-hospital mortality. METHODS: We conducted a population-based cohort study based on health records obtained from the National Health Insurance Service database in South Korea. All adult patients (⩾18 years old) who received ECMO treatment in the intensive care unit after hospitalization from 2005 to 2018 were enrolled. RESULTS: We ana

ECMO therapy initiated during a weekend was associated with a slightly increased risk of 60-day mortality compared to that associated with ECMO therapy initiated on a weekday. This association was more evident in patients who received ECMO therapy that started on a Saturday. Further studies are needed to confirm these findings.

Background While conventional electrocardiogram monitoring devices are useful for detecting atrial fibrillation, they have considerable drawbacks, including a short monitoring duration and invasive device implantation. The use of patch-type devices circumvents these drawbacks and has shown comparable diagnostic capability for the early detection of atrial fibrillation. Objective We aimed to determine whether a patch-type device (AT-Patch) applied to patients with a high risk of new-onset atrial

Electrocardiogram (ECG) changes after primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) patients are associated with prognosis. This study investigated the feasibility of predicting left ventricular (LV) dysfunction in STEMI patients using an artificial intelligence (AI)-enabled ECG algorithm developed to diagnose STEMI. Serial ECGs from 637 STEMI patients were analyzed with the AI algorithm, which quantified the probability of STEMI at variou

PURPOSE: We aimed to investigate whether the use of cardiovascular drugs in coronavirus disease 2019 (COVID-19) patients with hypertension as a comorbidity has a significant effect on the incidence and associated mortality rate of COVID-19. MATERIALS AND METHODS: Data covering the period between January 1, 2020 and June 4, 2020 were extracted from The National Health Insurance Service-COVID-19 (NHIS-COVID-19) database in South Korea and analyzed as a population-based cohort study. RESULTS: =0.01

Purpose: The prognosis of advanced hepatocellular carcinoma (HCC) is very grave. The most effective method to improve the survival rate of HCC patients is early diagnosis and curative resection. The aim of this study is to investigate risk factors affecting the recurrence of HCC after curative resection. Methods: We retrospectively analyzed 287 HCC patients who underwent surgical resection at Severence Hospital between Jan. 1998 and Dec. 2003. They consisted of 222 males and 65 females whose med

This study developed a machine learning-based Clinical Decision Support System (CDSS) by integrating an AI-derived Congestion Index (CIx) from chest X-rays with clinical and laboratory data in patients with acute decompensated heart failure (ADHF). Among 9,286 patients, the model incorporating imaging data showed the highest predictive accuracy (AUROC 0.750). CIx demonstrated prognostic performance comparable to NT-proBNP and showed a significant increase in event rates across quartiles. The fin

Background: This study aimed to investigate the association between opioid use and the incidence of major adverse cardiovascular events (MACEs). Methods: This study included adult patients who had received oral or transdermal opioids in 2016. The control group comprised individuals who did not receive opioids in 2016 and was selected using a 1:1 stratified random sampling procedure. A MACE was defined as the occurrence of acute myocardial infarction, stroke, heart failure, or cardiovascular mort
