About the Lab
Professor Bang Hoon Lee's research lab specializes in cardiovascular imaging and hemodynamics, with a focus on left ventricular structure and function, particularly in the context of hypertension and cardiac remodeling. The lab investigates the interplay between hemodynamic and non-hemodynamic factors—such as body size, gender, and visceral adiposity—on left ventricular mass and its implications for cardiovascular risk. Using echocardiographic techniques, including tissue Doppler imaging and advanced hemodynamic assessment, the lab explores early functional changes like diastolic dysfunction and their prognostic significance. The research also extends to rare cardiac conditions, such as cardiac hemangiomas, and the physiological behavior of ECG parameters like the PR interval during exercise.

15고혈압의 치료는 크게 생활 양식의 변화와 약물요법 으로 나눌 수 있으며, 약물 치료를 할 때는 고혈압의 병태 생리와 혈역동학적 변화, 관상동맥 질환의 위험 인자, 동반하고 있는 타 질환, 부작용, 환자의 순응도, 삶의 질 등 여러 가지 요소들을 고려하여 적절한 강압 제를 선택하는 것이 중요하다. 고혈압을 체계적으로 치료하기 위해 세계 각국에서의 여러가지 치료지침이 보고되어 왔다. 즉 1993년의 세계 보건 기구 및 국제 고혈압 학회(WHO/ISH)의 치료 지침, 미국의 제 5 차 합동 조사 연구 보고(JNC V), 카나다 고혈압 학 회, 영국 고혈압 학회의 보고와 1992년의 뉴질랜드 보고 1994년의 호주의 보고 등이 발표 되었다. 그러 나 이들 치료 지침들 사이에는 공통점이 있는 반면 여 러가지 문제점에 대한 이견과 결정 짓지 못하고 있는 사항도 있는게 사실이다. 1993년과 1994년에 보고된 치료 지침에서의 공통 된 점을 보면 심혈관계 위험인자의 중요성, 노인성 고 혈압 및
BACKGROUND AND OBJECTIVES: The structural significance of the inappropriateness of left ventricular mass (iLVM) is known to be an important prognostic factor for cardiovascular events; however, the functional changes associated with iLVM have not been established. This study was performed to determine if diastolic dysfunction is associated with iLVM using a tissue Doppler technique. SUBJECTS AND METHODS: Three hundred sixty consecutive subjects, including 221 hypertension patients from the echoc
BACKGROUND AND OBJECTIVE: Adipose tissue may be one of the sources of the humoral factors increasing left ventricular mass (LVM) via non-hemodynamic mechanisms. The involvement of visceral obesity in excessive or inappropriate LVM has not been established. We investigated the effect of abdominal circumference on the inappropriateness of LVM in non-obese patients. METHODS: Echocardiographic parameters for LVM and the indices for diastolic function were analyzed in 312 non-obese patients. Inapprop
OBJECTIVES: The PR interval on the electrocardiogram represents conduction time from the onset of atrial activation through His-Purkinje conduction system during a normal cardiac cycle. While its behavior at rest and during exposure to various cardioactive drugs is well documented, there exist few reports which describe PR interval variations during exercise in normal control and patient groups. In the present study, we examined the behavior of the PR intervals during various stages of exercise,
Cardiac hemangiomas are rare primary tumors of the heart and constitute only 2.8% of primary cardiac tumors. They are classified into capillary, cavernous, epitheloid and arteriovenous type and the last one is the most uncommon type. We experienced a case of cardiac hemangioma which was diagnosed as arteriovenous type for the first time in Korea in the literature. The patient was a 54-year-old woman who presented with palpitation and anterior chest pain. The diagnosis was based upon coronary ang
Background and Objectives:The left ventricular mass is known to be influenced by both hemodynamic and non-hemodynamic factors. Body size and gender are the most representative non-hemodynamic factors. This study was performed to establish the influences of these variables on the variation of the left ventricular mass in healthy Korean adults. Subjects and Methods:368 subjects (male=184, female=184), with a normal body mass index and blood pressure, were included in the echocardiographic analysis
Background and Objectives:Aging is a major factor related to a relaxation abnormality of the left ventricle. Increased arterial stiffness and central distribution of body fat are common physiologic changes observed in the elderly. To further elucidate the relationship between aging and a relaxation abnormality of the left ventricle, we investigate the relationship between the pulse wave velocity, abdominal obesity and diastolic function parameters of the left ventricle. Subjects and Methods:In 4
Background:Early diagnosis and treatment of hypertension is imperative to prevent the complications associated with this condition. The development of accurate and convenient methods of blood pressure measurement, therefore, is indispensible. At present, the JNC V has acknowledged the use of automatic sphygmomanometer that can be used without the help of someone else. We compared automatic oscillometric sphygmomanometers manufactured by Sein Electronics, korea (SE-7000 and SE-5000 with the stand
배경 및 목적： 최근 좌심실 질량의 결정인자에 대한 연구 영역이 혈역학적 인자에 국한되지 않고 비혈역학적 인자로 확대되면서 좌심실 질량의 적정성의 평가에 대한 연구가 활발해지고있다.1)2) 좌심실 질량의 적절성을 평가하기 위해서는 성장과 더불어 적절한 좌심실 증가에 관여하는 신장, 성별, 심박출일의 영향이 성인에서 어떻게 좌심실 질량과 관계되는지의 연구가 필요하다. 이에 본 연구는 한국인에서 좌심실 질량을 결정하는데 있어서 이들 인자의 관련성을 규명하기 위하여 시행되었다. 방 법：한양대학병원 심초음파실과 양평지역사회의학 연구 집단의 심초음파 데이터 베이스에서 정상체중, 정상 혈압인 성인 368명(남자 184명, 여자 184명)을 대상으로 하였다. 좌심실 질량은 1.04×(IVSd+LVDd+PWTd)3-LVDs3)×0.8-0.6 으로 계산하였고 일회심박출량은 Teichholz방정식에 의해 계산하였으며 일회심박출일은 수축기혈압×일회심박출량×0.00144로 계산하였다. 결 과：일회심박출일
