Filter by:The aim of the study is to evaluate the clinical implications of artificial Intelligence (AI)-assisted quantitative coronary angiography (QCA) and positron emission tomography (PET)-derived myocardial blood flow in clinically indicated patients.
There is no specific recommendation regarding pharmacologic treatment as primary prevention for patients with intermediate coronary artery stenosis whose revascularization was deferred based on negative fractional flow reserve (FFR). Current nationwide cohort study conducted using Korean National Health Insurance Service database evaluated the safety and efficacy of antiplatelet therapy in patients with intermediate coronary artery stenosis with deferred revascularization based on negative FFR (FFR>0.80).
The objective of this study is to evaluate the effectiveness and safety of Coroflex ISAR NEO stents in comparison to other drug-eluting stents (DES) in real-world practice.
This is a prospective, single-center study. The primary purpose of this study is to evaluate the sensitivity and specificity of offline computational ultrasonic flow ratio (UFR) with conventional pressure wire-based fractional flow reserve (FFR) as the standard reference. The study will be conducted in Fuwai Hospital, and a total of 408 patients with coronary vessel diameter stenosis ≥30% and ≤80% are planned to be recruited. Participants who meet the inclusion criteria and do not meet the exclusion criteria will undergo intravascular ultrasound (IVUS) followed by FFR examination. IVUS imaging will be sent to an independent core laboratory for UFR calculation. UFR analyses were performed offline in a blinded fashion without awareness of FFR measurement. Using FFR≤0.80 as the gold standard, the sensitivity and specificity of UFR in the functional significance of coronary artery stenosis will be analyzed.
The present case-control study is designed to investigate the disease characteristics of IR-CAD by comparing the demographics, clinical features, lab results, imaging findings, and prior treatment between 20 patients with IR-CAD and 10 patients with AS-CAD.
Flavonoids are one of the main groups of polyphenols. Anthocyanins, which are a subgroup of the flavonoid family, are found in a number of fruits and some vegetables. In epidemiological studies, high dietary intake of polyphenols has been associated with improvement of some cardiometabolic risk factors in high-risk individuals. Furthermore, in controlled studies, consumption of polyphenol-rich food sources or anthocyanin extract supplementation has improved some cardiometabolic factors. In the present study, the effect of diet enriched with anthocyanin-rich food sources on cardiometabolic factors will be studied in coronary artery disease patients.
The HYUMC registry is a two-center, real-world registry of percutaneous coronary intervention in patients with coronary artery disease. From January 2012, PCI-treated patients from Hanyang University Seoul Hospitals and Hanyang University Guri Hospitals were enrolled in this registry. The aim of this registry is to examine the long-term clinical outcomes and identify predictors of adverse outcomes following percutaneous coronary intervention conducted at academic hospitals.
This is a self-controlled cohort study to evaluate the efficacy and safety of comprehensive treatment in patients with inflammation-associated rapidly-progressive coronary artery disease (IR-CAD) by comparing the study endpoints before treatment with those after treatment in the same group of patients.
The objective of this randomized study was to compare outcomes of imaging-and physiology-guided state-of-the-art ercutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) in patients with diabetes and three-vessel CAD (not involving left main).
In this prospective, single-arm study, we will look at the initiation, participation, sustained engagement, and safety of 100 adult subjects (ages 45 years or older) with recent (within the past 60 days) clinician referral to CR who are offered CTR via the RecoveryPlus platform. We want to understand the effectiveness of the RecoveryPlus platform in engaging participants in CR while remaining a safe alternative for the delivery of evidence-based CR content. The primary hypothesis of this study is that the RecoveryPlus CTR platform and patient-facing mobile application provide a safe alternative to traditional in-person CR, and demonstrate a high rate of initiation, participation, and engagement in CR exercise programming than traditional modes of CR delivery, as documented in the literature. Current in-person and non-personalized CR programming lacks RecoveryPlus' convenient remote access, easy-to-use digital tools to support independent, autonomous exercise, and a platform to facilitate engagement and feedback between patients and EPs.
