About the Lab

Professor Ran Heo's research lab focuses on cardiovascular imaging and clinical outcomes, particularly in atrial fibrillation and heart failure. The lab investigates advanced echocardiographic techniques for left atrial assessment, symptom burden in arrhythmias, and the integration of imaging with hemodynamic and clinical phenotyping. A key emphasis is on translating novel imaging technologies—such as 3D echocardiography and CCTA—into practical tools for improved diagnosis and personalized treatment.

BACKGROUND: Left atrial (LA) sizing in patients with atrial fibrillation (AF) is crucial for follow-up and outcome. Recently, the automated quantification of LA using the novel three-beat averaging real-time three dimensional echocardiography (3BA-RT3DE) is introduced. The aim of this study was to assess the feasibility and accuracy of 3BA-RT3DE in patients with atrial fibrillation (AF). METHODS: Thirty-one patients with AF (62.8 ± 11.7 years, 67.7 % male) were prospectively recruited to have tw

Abstract Background Symptom burden is an important factor in determining the treatment of atrial fibrillation (AF). AF is frequently accompanied by heart failure (HF). This study investigated the characteristics of AF symptoms with concomitant HF. Methods A total of 4885 patients with AF were consecutively enrolled through a prospective observational registry (the Comparison Study of Drugs for Symptom Control and Complication Prevention of Atrial Fibrillation [CODE-AF] registry). Clinically diag

Wrist devices with both accuracy and feasibility, new option to measure nocturnal blood pressure?
Ran Heo, Jinho Shin
SJR Q2Journal of Clinical HypertensionOA

Nocturnal blood pressure (BP) is very well-known for its association with adverse cardiovascular outcomes. Even though there have been many clinical studies investigating the epidemiology and therapeutics to control nocturnal BP, there are limitations in gathering data to apply to clinical trials and generating clinical evidence for real world clinical practice. First, the reproducibility of nocturnal blood pressure and/or its dipping patterns performed during a single day are not sufficiently a

Machine-learning based prediction of obstructive coronary artery disease using integrated submodules of clinical information, chest x-ray, and electrocardiography

SJR Q1European Heart JournalOA

Abstract Background The early diagnosis of obstructive coronary artery disease (CAD) is critical. However, delays in diagnosis may occur due to subsequent high-cost tests, contributing to substantial medical expenses. A more insightful interpretation of fundamental diagnostic tools, such as chest x-ray (CXR) and electrocardiography (ECG), could mitigate medical costs and facilitate a timely diagnosis. Purpose This study explores the application of machine learning to interpret each modality and
