Filter by:Drug-eluting stents iterations has significantly improved the results of percutaneous revascularization among patients undergoing coronary revascularization thanks to thinner struts, more biocompatible polymer coatings and new drug release formulations; leading to lower thrombogenicity, faster reendothelialization and improved clinical outcomes. Notwithstanding, stent-related events yet occur. Lesion pre-dilation prior to DES implantation is a crucial procedural step as it creates microdissections, which are required for optimal uptake of the drug. However, the best pre-dilation strategy has not yet been determined. Therefore, the aim of this study is to evaluate a strategy based on pre-dilation with cutting balloon (CB) followed by Abluminus Sirolimus-eluting stent (ASES) implantation for de novo coronary lesions
This study evaluates plaque progression and characteristics in patients with coronary atherosclerosis.
Coronary calcified lesion is associated with a poor clinical outcome. Intravascular ultrasound (IVUS) provides anatomic information in detail about reference vessel dimensions and lesion characteristics including severity of diameter stenosis, lesion length, and morphology. Both randomized and observational studies have reported the clinical benefits of IVUS guidance for patients with chronic total occlusion (CTO), long lesions, acute coronary syndrome (ACS) with complex bifurcation lesions. Our previous ULTIMATE trial has demonstrated that IVUS-guided drug-eluting stent (DES) implantation significantly improved clinical outcome in all-comers, particularly for patients who had an IVUS-defined optimal procedure, compared with angiography guidance. However, the benefit of IVUS guidance in coronary severe calcification still remains unknown in the modern DES era.
Prospective, multi-center, open-label single-arm study designed to enroll 85 patients in up to 15 centers in up to 3 European countries. All patients will be followed up for 9 months. The "BMX Alpha Registry" study will serve as reference and historic comparator.
A pragmatic, prospective, multi-center, open label, randomized controlled, superiority trial. The study will compare clinical outcomes between invasive versus non-invasive approach as next diagnostic step in symptomatic patients with non-high risk obstructive coronary artery disease (CAD) on coronary computed tomography-angiography (CCTA).
This is a prospective observational study aimed at testing the existence of an association between frailty, inflammatory status, and degree of platelet activation and reactivity in elderly subjects with type 2 diabetes or coronary artery disease or Alzheimer's disease.
Primary Study Objective : To compare the effects of low-dose rivaroxaban plus aspirin versus aspirin on atherosclerotic plaque inflammation using serial FDG Positron Emission Tomography/Computed Tomography(PET-CT) imaging of carotid artery and ascending aorta. Secondary Study Objective : To compare the effects of low-dose rivaroxaban plus aspirin versus aspirin on biomarkers including high-sensitivity C-Reactive Protein(CRP) and lipid profiles.
The purpose of the SMART-EXAM (SMart Angioplasty Research Team-Pragmatic Randomized Trial for Comparing Routine versus As-Needed EXercise or Pharmacologic Stress Testing in Asymptomatic Patients with High-Risk Coronary CalciuM) trial is to compare the major adverse cardiovascular events between routine stress testing and as-needed stress testing in asymptomatic patients with high-risk coronary calcium (Agatston Score ≥ 400) without proven ASCVD.
Background: This study aims to determine the effects of communicating genetic risk for Coronary Heart Disease (CHD) alone or in combination with goal setting and prompts from a wearable device on objectively measured sedentary time (ST) in East Asians. It is hypothesized that this combination will lead to significant favorable changes in objectively ST, and that such changes will be more likely to be sustained over 6-month follow-up. Methods: In a parallel group, randomized controlled trial, a total 414 individuals of East Asians aged over 60years will be allocated into one of three groups: 1 control and 2 intervention groups. Blood samples will be used for estimation of CHD genetic and analysis of metabolic risk markers. Genetic risk for CHD will be estimated based on recently identified 79 SNPs (associated with CHD for East Asians) using an established methodology. Questionnaires and physical measurement will be administered at Before and after the 12-month intervention and at 6-month follow-up. Each group will receive a Fitbit device. Both intervention groups will be given CHD genetic risk estimates along with lifestyle advice but one of them will additionally use Fitbit's step-goal setting and prompt functions. The primary outcome is objectively measured sedentary time. Secondary outcomes include objectively measured MVPA, calories burned, and five intermediate metabolic risk markers (total cholesterol/HDL-C/LDL-C/triglycerides).
This study seeks to expand the use of the NYU GeriKit mobile application ("app") in a diverse range of settings to better phenotype older patients, which will enhance both research and patient care.
