Low-Carbohydrate and Plant-Based Dietary Effects on Vascular Health

Start date: December 20, 2022
Phase: N/A
Study type: Interventional

This is a randomized trial with a crossover design to investigate the short-term effects of two different dietary patterns on markers of vascular health. A low-carbohydrate diet and a whole-food, plant-based diet will be used. In addition to more traditional markers (cholesterol, blood pressure, inflammation), endothelial progenitor cells and trimethylamine N-oxide will be assessed.

Carotid Plaque Length to Predict Cardiovascular Events

Start date: January 1, 2017
Phase:
Study type: Observational

This multicenter study involved 5 hospitals (Changhai Hospital; Yueyang Hospital of Shanghai University of Traditional Chinese Medicine; Gongli Hospital; Putuo Hospital of Shanghai University of Traditional Chinese Medicine; No. 904 Hospital of the PLA Joint Logistics Support Force Wuxi). The study enrolled 5000 patients for suspected CAD who referred to coronary angiography from January 2017 through December 2018.

NCT ID: NCT05364463 Active, not recruiting - Myocardial Ischemia Clinical Trials

Effect of Reactive Hyperemia and Ultrasound-guided Puncture on the Success Rate of Radial Artery Cannulation (RadialHUS)

RadialHUS
Start date: February 17, 2022
Phase: N/A
Study type: Interventional

Aims: to evaluate the success rate of radial artery cannulation in patients undergoing cardiac catheterization, using different methods such as palpation, hyperemia or ultrasound-guided puncture, together or each method separately. Specifically, the success rate at the first attempt, the number of attempts with each technique and the time spent will be assessed. The hypothesis is that there are different success rates for each puncture technique when cannulating radial artery for cardiac catheterization. Methods: randomized clinical trial with four parallel groups, with operator blinding. Those patients who will have the radial artery cannulated for an interventional cardiology procedure will be selected. Once the participant agrees to be included in the study and signs the informed consent, they are randomized to one of four groups: ultrasound and hyperemia puncture, only ultrasound puncture, only hyperemia puncture, palpation puncture (control group). Subsequently, an ultrasound assessment of the participant's radial artery (diameter, depth and systolic peak velocity) will be performed. Once in the intervention room, the puncture will be performed according to the corresponding method. The puncturing operator in charge will not perform the randomization or the ultrasound assessment to avoid bias. Variables will be collected in an ad hoc questionnaire designed to respond all study aims. Regarding the sample size, accepting an alpha risk of 0.05 and a beta risk of 0.2 in a bilateral contrast, 92 subjects per group are required to detect significant differences. Therefore, the total sample size would be made up of 368 participants, estimating losses of 5%. For variables description and hypotheses contrast, the statistical program SPSS version 22.0 for Windows will be used, working with a significance level of 5%.

NCT ID: NCT05292287 Active, not recruiting - Clinical trials for Coronary Heart Disease

Remote Maintenance Cardiac Rehabilitation

MAINTAIN
Start date: March 28, 2022
Phase: N/A
Study type: Interventional

The investigators would like to test the feasibility of a remotely prescribed and monitored exercise program in people with coronary heart disease, using a wearable activity device and text message support, compared to usual care after completing cardiac rehabilitation. One group will use a Polar Ignite watch to guide them through exercise sessions at home and will receive text message feedback. The other group will be asked to continue their routine as usual. Assessments of both groups will happen after the completion of cardiac rehabilitation and at three follow-up time points of three, six, and twelve months. The aim of these treatments is to see if the investigators can help people to maintain their exercise adherence and coronary heart disease risk factor management after completing cardiac rehabilitation.

NCT ID: NCT05210725 Active, not recruiting - Clinical trials for Coronary Artery Disease

Trained Immunity by Dual-pathway Inhibition in Coronary Artery Disease

DUALCAD
Start date: March 1, 2022
Phase: Phase 4
Study type: Interventional

Coronary artery disease (CAD) is a manifestation of systemic atherosclerosis for which single antiplatelet therapy (SAPT) is indicated if patients are stable. Recently dual pathway inhibition (DPI) by combining a low-dose factor Xa inhibitor (rivaroxaban2.5mg twice daily) with a single platelet inhibitor (ASA) has been demonstrated to be beneficial in treating CAD. The exact mechanisms underlying the benefits of DPI, are not completely understood. CAD is characterised by a state of chronic low-grade inflammation, where monocytes from CAD patients have a higher immune responsiveness to ex vivo stimulation with lipopolysaccharide (LPS) compared to healthy matched controls. Surprisingly, the investigators have recently observed an elevation in ex vivo immune responsiveness to LPS stimulation when switching from ASA monotherapy to DPI of ASA combined with rivaroxaban inpatients with peripheral arterial disease (n=11; unpublished). Remarkably this was associated with no changes in systemic inflammation, as determined by Olink proteomics analysis. These findings suggest that factor Xa inhibitors can enhance immune cell responsiveness despite being clinically beneficial to CAD. The exact mechanisms contributing to the observed increased immune responsiveness remain unexplored.

NCT ID: NCT05171283 Active, not recruiting - Clinical trials for Cardiovascular Diseases

Meta-analysis of Oat Fiber and Cardiovascular Risk Reduction

Start date: November 1, 2021
Phase:
Study type: Observational

Oat fibre has been shown to lower cholesterol and may have cardioprotective effects. However, whether this translates to actual cardiovascular risk reduction is unclear, as there is a lack of controlled human trials. To address this uncertainty, the investigator proposes to use established cardiovascular disease risk scores, such as those recommended by the Canadian Cardiovascular Society and other clinical practice groups, to create composite risk scores in assessing future risk. The data on oat fibre will be collected through a systematic review of controlled trials, composite cardiovascular risk scores will be calculated for each eligible study, and meta-analyses will be conducted to assess the overall effect. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design.
