Filter by:The primary objective of this study is to assess the accuracy in terms of sensitivity, specificity, negative and positive predicted values of the DL-based algorithm with respect to correct identification of the plaque and associated vulnerability grade.
This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR > 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
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.
The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
The aim of this study is to evaluate feasibility, efficacy, and adherence of home-based cardiac rehabilitation with the integration of telemedicine. Several components will be assessed such as quality-of-life, nutritional counseling, maximum metabolic activity (MET's), diabetic management, tobacco cessation, lipid, blood pressure, and psychosocial management. These tasks will be accomplished through concurrent conversations between patients and their therapist's utilizing telemedicine with observed exercise training.
Cardiac rehabilitation is a medically recommended program for patients with certain heart conditions. It includes exercise training, health education, and counseling. Unfortunately, many patients do not participate in cardiac rehabilitation. Some find it challenging to attend the in-person sessions. This study aims to compare two methods of delivering cardiac rehabilitation: in-person and through telehealth. The investigators want to know if the effects of these two programs are alike and if certain individuals benefit more from one program over the other.
The association of novel inflammatory biomarkers with cardiovascular diseases is still obscure. The present study aimed to investigate the relationship of various inflammatory biomarkers with the existence as well as the extent of heart failure (HF) and coronary artery disease (CAD), suggesting a link between inflammation and cardiovascular diseases and all-cause 30- and -90 day of hospital readmission. Methods: We enrolled a total of 120 patients with HF, asymptomatic CAD and 60 healthy controls (HC) without cardiovascular diseases.
We will establish a cohort of 570 symptomatic chronic coronary syndrome patients undergoing 15O-water PET and assess their symptoms through repeated questionnaires. Two hundred patients with abnormal perfusion will be randomized to immediate or delayed referral to invasive coronary angiography with concomitant optimization of guideline-directed medical therapy with repeated 15O-water PET and questionnaires at 3 and 6 months. The primary objective is to compare the potential benefit of early invasive coronary angiography (ICA) versus guideline directed medical therapy (GDMT) on symptomatic relief defined as freedom of angina after 3 months following a positive [15O]H2O cardiac PET/CT in patients with symptomatic chronic coronary syndrome.
Elective PCI were included in the study. Patients were randomized into two different groups. One group took ASA 80 mg once daily and clopidogrel 75 mg once a day, and the other one took ASA 80 mg once a day and ticagrelor 90 mg twice a day. After six months of close follow-up, patients were asked to give a score to their dyspnea and asked about the major advance cardiovascular events ( MACE)
