Discontinuation rates, clinical effects and provocation factors of SGLT-2 inhibitor in the real world.

Sci Rep

December 2024

Division of Cardiology, Department of Medicine, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.

Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are the only medications that improve clinical outcomes regardless of baseline left ventricular ejection fraction. Despite the recognized effectiveness of SGLT-2 inhibitors, there remains a paucity of research on the discontinuation of these medications. The objective of this study is to analyze the rate of discontinuation of SGLT-2 inhibitors, to evaluate the impact of discontinuation on the clinical outcome, and to identify the factors associated with discontinuation.

December 2024

Department of Neurological Surgery, University of Pittsburgh School of Medicine, Pittsburgh, PA 15213, United States; Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, PA 15213, United States. Electronic address:

Background: Anterior cerebral artery (ACA) occlusions account for up to 4 % of all acute ischemic strokes and may lead to debilitating outcomes. While endovascular thrombectomy (EVT) is a well-established treatment for large vessel occlusions, its efficacy and safety for primary ACA occlusions remains unclear. This systematic review and meta-analysis aims to address this gap by evaluating the clinical outcomes, safety, and efficacy of EVT in the treatment for primary ACA occlusions.

Brain Neurorehabil

November 2024

Department of Physical and Rehabilitation Medicine, Center for Prevention and Rehabilitation, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.

Article Synopsis
  • - Post-stroke cognitive impairment (PSCI) significantly impacts many stroke patients, increasing their risk of mortality, dependency, and needing long-term care.
  • - Early identification of risk factors for PSCI and the initiation of cognitive rehabilitation can improve patients’ quality of life and lessen the burden on their families.
  • - Most PSCI risk factors are non-modifiable, but managing stroke risk factors can be controlled; further research is needed to explore effective cognitive rehabilitation programs.

Prognostic impact of intravascular imaging in percutaneous coronary intervention according to atherothrombotic risk: a post hoc analysis of a randomized clinical trial.

Rev Esp Cardiol (Engl Ed)

December 2024

Division of Cardiology, Department of Medicine, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea. Electronic address:

Introduction And Objectives: Recent randomized controlled trials support the use of intravascular imaging-guided percutaneous coronary intervention (PCI) to improve patient prognosis. However, the subsequent risk of clinical events in patients with coronary artery disease is not determined solely by lesion characteristics or how these lesions are treated. The current study investigated whether the effects of intravascular imaging in complex PCI vary according to atherothrombotic risks.

Background And Objectives: The Fractional Flow Reserve and Intravascular Ultrasound-Guided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea.

Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).

Safety and Efficacy of Pivot-Balloon for Severe Tricuspid Regurgitation: The First-in-Man Experiences.

Korean Circ J

October 2024

Division of Cardiology, Department of Medicine, Heart Vascular Stroke Institute, Samsung Medical Center, Sungkyunkwan University, Seoul, Korea.

Background And Objectives: Among various emerging catheter-based treatments for severe tricuspid regurgitation (TR), the spacer device can reduce the regurgitation orifice without manipulating the valve leaflet. However, its clinical application has been hampered by traumatic anchoring to the myocardium and the coaxial alignment of the balloon resulting in insufficient TR reduction. This study aimed to evaluate the early-stage safety, technical feasibility, and preliminary efficacy of the novel atraumatic vertical spacer in patients with isolated severe TR.
