연구실 소개
고규용 교수의 연구실은 허혈성 심장질환, 특히 급성 심근경색과 대동맥판막질환에서의 미세순환 기능과 심장구조 변화의 임상적 의미를 중심으로 연구를 진행하고 있습니다. 특히 스텐트 삽입술 후 미세순환 기능 저하를 평가하고 개선 전략을 모색하는 데 초점을 맞추며, 에코카디오그래피와 CT를 활용한 정밀한 해부학적 평가 및 예후 예측 모델 개발에도 기여하고 있습니다. 심부전, 뇌졸중 등 심혈관계 합병증 예방을 위한 조기 진단 및 치료 전략 수립이 핵심 목표입니다.

15Thrombus aspiration as an adjunctive method to primary PCI for STEMI may preserve microvascular integrity and have beneficial effects on myocardial microcirculation.
Background Left atrial (LA) remodeling is associated with adverse cardiovascular events, including heart failure (HF) and stroke in patients with atrial fibrillation (AF). However, there are limited data on the value of right atrial (RA) remodeling in this population. We investigated the prognostic role of RA enlargement in patients with non-valvular AF. Methods and results We analyzed 254 consecutive patients (age = 69 ± 12years, male:female = 165:89, mean left ventricular ejection fraction = 5
Objectives . We aimed to identify mechanical and pharmacological revascularization strategies correlated with the index of microcirculatory resistance (IMR) in ST-elevation myocardial infarction (STEMI) patients. Background . Microvascular dysfunction (MVD) after STEMI is correlated with infarct size and poor long-term prognosis, and the IMR is a useful analytical method for the quantitative assessment of MVD. However, therapeutic strategies that can reliably reduce MVD remain uncertain. Methods
Background Rheumatic mitral stenosis is a significant cause of valvular heart disease. Pulmonary arterial systolic pressure (PASP) reflects the hemodynamic consequences of mitral stenosis and is used to determine treatment strategies. However, PASP progression and expected outcomes based on PASP changes in patients with moderately severe mitral stenosis remain unclear. Methods and Results A total of 436 patients with moderately severe rheumatic mitral stenosis (valve area 1.0–1.5 cm 2 ) were enr
AIMS: This study compared echocardiography (echo) and cardiac computed tomography (CT) in measuring the Wilkins score and evaluated the potential added benefit of CT in predicting immediate percutaneous mitral valvuloplasty (PMV) outcomes in rheumatic mitral stenosis (MS) patients deemed eligible for PMV by echo. METHODS AND RESULTS: From a multicentre registry of 3,140 patients with at least moderate MS, we included 96 patients (age 56.4 ± 11.5 years, 81% female) eligible for PMV based on echo
An early AVR strategy may be beneficial in reducing the risk of a composite outcome of death or hospitalization for HF in symptomatic patients with NFLG severe AS. Future randomized studies are required to validate and confirm our findings.
Achieving an increase in ∆MVA of >0.5 cm<sup>2</sup>was found to be correlated with improved outcomes. This suggests that, in addition to achieving traditional optimal results, targeting an increase in ∆MVA of >0.5 cm<sup>2</sup>could be a beneficial objective in PMV treatment for RMS.
This study observed an increase in patient age, comorbidities, and valve disease severity as the country transitioned from a developing to developed status. Despite a rise in mitral valve interventions, clinical outcomes deteriorated over 20 years, highlighting the need for modified treatment approaches to improve patient outcomes.
Ivabradine is a selective inhibitor of the sinoatrial node "funny" current, prolonging the slow diastolic depolarization. As it has the ability to block the heart rate selectively, it is more effective at a faster heart rate. It is recommended for the treatment of heart failure reduced ejection fraction in the presence of beta-blocker therapy for the further reduction of the heart rate. However, previous reports have shown the association of Torsade de pointes (TdP) with concurrent use of ivabra
The management and follow-up of moderate aortic stenosis (AS) lacks consensus as the progression patterns are not well understood. This study aimed to identify the hemodynamic progression of AS, and associated risk factors and outcomes. We included patients with moderate AS with at least three transthoracic echocardiography (TTE) studies performed between 2010 and 2021. Latent class trajectory modeling was used to classify AS groups with distinctive hemodynamic trajectories, which were determine
BACKGROUND: Long-term follow-up studies in severe mitral stenosis (MS) with low transmitral mean diastolic pressure gradient (MDPG) are not available. We evaluated the prognostic implications of severe MS with low MDPG in our MASTER (Multicenter Mitral Stenosis with Rheumatic Etiology) registry. METHODS: We included patients with severe rheumatic MS (mitral valve area ≤1.5 cm 2 ) from the long-term MASTER registry. Patients were categorized into high (≥5 mm Hg) or low (<5 mm Hg) MDPG groups.
ICE was comparable to TEE for guidance during TAVR for the composite clinical efficacy outcome, with similar incidences of moderate-to-severe PVR, new permanent pacemaker implantation, and major bleeding. These results suggest that ICE could be a safe and effective alternative echocardiographic modality to TEE for guiding TAVR.
