Filter by:The study aims to evaluate clinical characteristics and prognostic of a contemporary population of patients with UA defined using T hs-cTn measurements The study includes all patients admitted in 2 French university centers with the confirmed diagnostic of UA defined with clinical ischemic symptoms and T hs-cTn concentrations < 99 percentile (undetectable: <5ng/l or non-elevated: <14ng/l), or ≥ 99 percentile but mildly elevated (14-50ng/l) .The primary end-point included major events at 1-year follow-up (total mortality, new ACS, hospitalization for cardiac causes).
The primary objective of this study is to determine whether a reduced radiation protocol (RRP) in which angiograms are acquired at ultralow radiation doses and then processed using spatiotemporal enhancement software can produce similar quality angiographic images as compared with standard techniques.
The goal of this clinical trial is to determine if a standardized 12-point acupuncture protocol will reduce pain in participants with stable angina. This study addresses the critical need to reduce persistent pain for angina. The investigators long-term goal is symptom management for diverse women and men with angina, targeting additional angina burden borne of social disadvantage Participants will be randomized to a 10-acupuncture session protocol, two treatments per week for five weeks, or an attention control group. Participants will view designated, non-pain related Technology, Entertainment, Design Talks equal to the time spent receiving acupuncture (~7.5-10 hrs.). The investigators will test the efficacy of acupuncture for stable angina/chest pain syndrome to reduce pain and symptoms, improve health-related quality of life, reduce healthcare utilization and and improve patient related health outcomes.
The purpose of this study is to assess in recently diagnosed stable Angina patients symptomatic despite first line hemodynamic therapy, the effect of a combination of this hemodynamic agent with a metabolic one (trimetazidine). The treatment effect will be measured by the reduction of patients' angina symptoms, physical limitation and an improvement of quality of life using the Seattle Angina Questionnaire-7 items (SAQ-7) Patients will be also proposed to complete a BEAMER (BEhavioral and Adherence Model for improving quality, health outcomes and cost-Effectiveness of healthcaRe) questionnaire which will contribute to a separate research project developed by the Innovative Medicines Initiative (IMI). Analysis of the BEAMER questionnaires will be performed outside the study by the IMI BEAMER Consortium for BEAMER purposes only.
The increasing number of coronary revascularization procedures, coupled with improvements in drug therapy, has significantly extended the lifespan of patients with coronary artery disease (CAD). However, there remains a significant number of CAD patients who experience disability due to chronic refractory angina pectoris. These patients typically have severe diffuse CAD and are not candidates for further revascularization involving surgical coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). The installation of a coronary sinus reducer (CSR) represents a new option for percutaneous treatment of patients with refractory angina pectoris who are not suitable for surgical or percutaneous revascularization. The CSR device is designed as an hourglass-shaped stent that is positioned transcatheterally in the distal part of the coronary sinus. This increases intramyocardial venous pressure, which is believed to lead to a more favorable perfusion ratio between the ischemic subendocardial and non-ischemic subepicardial myocardium. Previous research has demonstrated that the implantation of CSR is a safe and relatively straightforward procedure. However, broader implementation and better patient selection are still limited by the fact that the exact mechanism of action remains controversial. It has not been determined why some patients have better outcomes compared to others with seemingly similar coronary artery disease. It is known that patients with atherosclerotic changes in the epicardial coronary arteries also have a certain degree of coronary microcirculation disease (the coronary vascular bed encompassing vessels with a diameter < 200 μm), which cannot be assessed through standard coronary angiography. This study aims to assess changes in coronary microcirculation after the implantation of CSR by measuring coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) before and 6 months after the procedure. Furthermore, our goal is to associate these changes with clinical symptoms and myocardial ischemia.
The primary objective of this study is to determine whether a reduced radiation protocol (RRP) in which angiograms are acquired at ultralow radiation doses and then processed using spatiotemporal enhancement software can produce similar quality angiographic images as compared with standard techniques.
According to the 2020 Dutch guideline on chest pain (AP) without obstructive coronary artery disease, 70% of female and 30% of male patients undergoing a coronary angiogram (CAG), have no obstructive coronary artery disease.In the majority of patients the complaints are based on vascular dysfunction, including epicardial vascular spasms. For patients who are refractory to drug treatment, spinal cord stimulation (SCS) can be a treatment option. SCS is used for the treatment of refractory neuropathic and ischaemic pain. In recent studies the use of SCS is proven for refractory angina pectoris, but the group with refractory vasospastic angina pectoris (rVSA) predominantly seen in women with invalidating impairment of quality of life, is overlooked, as no evidence of obstruction is found at CAG. With this pilot study the investigators hypothesize that SCS is effective in reducing the number and intensity of angina attacks, reducing nitrate use, reducing inhospital treatment and ER presentations, thereby reducing medical costs, and above all, increasing quality of life.
For women that experience angina symptoms with underlying vascular spasm as the cause, stress has an aggravating role. Coping with stress is therefore included as an important pillar in dealing with this chronic disease, see the European Association of Percutaneous Cardiovascular Interventions (EACPI) consensus document on INOCA. In practice, stress management focuses on informing and identifying the role stress plays in their lives. A potential stress management tool: "Wavy" aims to help users manage stress more consciously through biofeedback. This research focuses on the effectiveness of stress management applications. The hypothesis is that the app will help to avoid the trigger stress as much as possible and thus reduce the burden of disease.
Distal radial access (DRA) in the anatomical snuffbox (AS) is a relatively novel approach that can be considered an alternative to trans radial access (TRA) for coronary procedures. Several observational and randomized studies have established its feasibility and safety, with evidence of certain advantages over TRA, such as a reduction in hemostasis time, a lower incidence of complications at the puncture site, and a lower incidence of radial artery occlusion (RAO). Notwithstanding that a recent randomized study reported a similar RAO rate between DRA and TRA, several meta-analyzes confirm the advantages of DRA, despite a consistently higher crossover rate. The objective of this observational study is to assess the performance of the procedure and to compare clinical characteristics in an all-comer population undergoing diagnostic or interventional coronary procedures. The main questions it aims to answer are: - Determine the success rate of DRA and measure the incidence of RAO in an all-comer population undergoing coronary procedures. - Compare the clinical and anatomical characteristics of patients with DRA for coronary procedures and determine predictors of failure of access.
Aim of the study is to evaluate chronic total coronary occlusion treatment results 6 years after bioresorbable scaffold implantation by quantitative coronary analysis, intravascular ultrasound and optical coherence tomography.
