NCT06945003
Congenital heart disease (CHD) is the most common birth defect worldwide and occurs in every 8-10 per 1000 live births in Northern Ireland. The ability to participate in physical activity (PA) is an important aspect to an individual's quality of life. The UK Chief Medical Officer currently recommends that children aged 5-18 years should aim to achieve a minimum of 60 minutes PA per day. However, in Northern Ireland, only 8% of children with CHD are meeting these guidelines. This may be attributed to parents not allowing their child to fully participate in PA due to anxiety regarding its effect on their child's condition. Whilst, several studies to date have investigated the concerns faced by parents/guardians, this study is novel in its inclusion of teachers/coaches. Therefore, the investigators conducted interviews with parents/guardians and teachers/coaches to identify their concerns, highlighting that an individualised PA plan would help alleviate these fears. This has informed a PA intervention, whereby the intervention group will receive an individualised PA plan to implement at home over a 12 week period with a 3 and 6 month follow up. This plan will also be sent out to teachers/coaches to inform them of what PA is both safe and beneficial for each child. The PA plan is adapted specifically for each child to increase their exercise capacity as this will increase their cardiorespiratory function and health related quality of life. It is also anticipated that it will increase PA level, thus increasing the percentage of children with CHD meeting current PA guidelines. Therefore, the overall aim of this randomised control trial (RCT) is to assess the effectiveness of an individualised PA programme on exercise capacity and PA levels in children and adolescents with CHD. This will be assessed using both qualitative and quantitative methods.
NCT06279000
Perioperative myocardial injury and major adverse cardiovascular events (MACE) are common causes of morbidity and mortality in patients at increased cardiovascular risk undergoing non-cardiac surgery. However, research in recent years has yielded limited preventive and therapeutic measures for myocardial injury/MACE. Recent studies in patients with chronic and acute coronary artery disease have shown that colchicine administration can reduce the risk of cardiovascular events. These encouraging results in non-surgical patients ask for a similar investigation in patients undergoing major non-cardiac surgery. The aim of the proposed study is to investigate the effects of perioperative colchicine administration on the incidence of myocardial injury/MACE.
NCT06645327
To investigate the superior vena cava collapsibility index (SVC-CI), measured via transesophageal echocardiography (TEE), as a marker of fluid responsiveness. Two groups will be compared in this study. Groups will be identified by obtaining cardiac output (CO) by standard means using the TEE or pulmonary arterial catheter (PAC). Both of these monitors are considered standard for patient's undergoing coronary artery bypass grafting surgery (CABG) and recording initial CO readings. Based on CO, the patient's will be placed in study groups one or two. Participants with normal and mildly reduced left ventricular ejection fraction (LVEF \>40%) for group one and those with moderately to severely reduced LVEF (\<40%) in the second group. Following group separation, we will measure the SVC-CI and CO metric in both groups. The intervention will be an operating room table tilt test (head up and then head down) to artificially simulate giving the patient additional fluid. Before and after table tilt, the SVC-CI and CO will be obtained and measured. The SVC-CI is a mathematical equation determined by distance measurements taken via TEE to identify how much the superior vena cava has collapsed following table tilt. Participants will be considered responders if the CO increases by 12% following intervention. Non responders less than 12% change in CO following intervention. Our hypothesis is that the SVC-CI can differentiate responders vs non-responders with regards to fluid responsiveness with adequate sensitivity and specificity in participants with CAD undergoing isolated CABG. The SVC-CI numerical values for the two groups, responders and non-responders, will calculate a threshold of sensitivity and specificity percentages for future patients undergoing CABG.
NCT06053177
People with type 2 diabetes are at risk of complications linked with high blood sugars and these are monitored for in healthcare appointments. However, people with type 2 diabetes commonly suffer with additional health conditions that can affect the liver, heart and their breathing while sleeping. These conditions are thought to be caused by a similar underlying process that causes type 2 diabetes, as a result they are very common in people type 2 diabetes. Despite this they are not part of the routine health check for these people. Worryingly, current research suggests that the risk for developing these health problems, and direct complications of type 2 diabetes, can start at blood sugar levels below the threshold of type 2 diabetes. In a group of people said to have prediabetes. These people do not currently undergo annual healthcare appointments to monitor for these health complications or other linked health conditions. This study aims to pilot a new style of clinic to address these issues. The investigators will perform a multi-morbidity assessment, where they will look for several different health problems at the same time. The investigators will be looking at health problems linked with high blood sugars, this will include problems with the liver, heart, nerves, eyes, and participants breathing overnight. They have developed a clinic visit which uses questionnaires, simple examination techniques and modern devices to try and identify these health problems. An important part of healthcare is the burden it places on people with health problems, with this in mind the investigators will be giving the people involved in their study a voice to try and direct future research and healthcare, the investigators will ask them to provide feedback on their experience in taking part in the study and what their thoughts are in undergoing a longer but more comprehensive health appointment.

NCT06935786
The goal of this study is to learn if a simple home exercise program can benefit patients with advanced chronic kidney disease. There is also an observational part of the study without an exercise program. The study will record patients' mortality, cardiovascular events, emergency department visits, hospital stays, need for dialysis and 6 minutes walking distance. Also maximal oxygen uptake, quality of life and bone fractures are recorded and blood tests and X-rays analyzed. The prospective observational part of the study will investigate the link between cardiovascular and kidney health as well as exercise capacity and adverse outcomes.
NCT04693884
This two-phase project seeks to examine the cardiovascular response to consumption of cannabis variants of different cannabinoid composition through different methods (smoking vs. vaporizing), at rest and during aerobic exercise. Multiple measures that have been shown to predict risk factors for chronic-disease and negative health outcomes will be assessed following cannabis consumption at rest or in combination with exercise. These techniques will examine arterial stiffness, vascular function, and cardiac function. In phase I and II, subjects will visit the lab on 6 different occasions; with 1 visit acting as an introductory visit, 1 as an exercise control visit, 2 as resting cannabis visits, and 2 as cannabis + exercise visits. Cannabis used in phase I of this study will consist of approximately 10% THC. On all visits, pulse wave velocity, flow mediated dilation, and echocardiography measures will be performed following cannabis consumption by smoking or vaporizing, and cannabis consumption by smoking or vaporizing followed by 20 minutes of exercise on a cycle ergometer. Phase II of the study will implore a similar design. In favor of altering method of consumption, in all visits cannabis will be consumed by vaporization and will be either a high cannabidiol (CBD: (\~10%)) and low delta-9-tetrahydrocannabinol (THC: (\<1%)), or a high THC (\~10%) and low CBD (\<1%) variant.
NCT06335901
This study evaluated and compared the prognostic value of different Baseline data and clinical variables to develop predictive model in patients with CHD.
NCT06821191
Dual antiplatelet therapy (DAPT) with low-dose aspirin and a P2Y12 inhibitor is the current standard of care in patients with coronary artery disease experiencing an acute event or undergoing percutaneous coronary intervention. However, the ischemic benefits are counterbalanced by a significant increase in bleeding events. Over time, different DAPT de-escalation strategies have been developed to reduce the bleeding risk while maintaining the ischemic protection, but there is currently no head-to-head comparison between them. The purpose of this clinical trial is to conduct a head-to-head comparison on the pharmacodynamic efficacy of DAPT de-escalation by dose reduction to low-dose prasugrel (5 mg od) and DAPT de-escation by switching from standard-dose more potent P2Y12 receptor inhibitor to standard-dose clopidogrel (75 mg). To determine if the PD profiles of these two strategies are comparable, we aim to conduct a non-inferiority study.
NCT06927791
The research project aims to develop clinical decision support tools integrating established diagnostic variables and machine learning (ML) models for rapid diagnosis of acute life-threatening cardiovascular conditions in emergency department (ED) patients with chest pain or dyspnea with the ultimate goal of Improved diagnostic accuracy, faster patient management, and reduced medical errors.

NCT02258724
Due to successes in the last decades in pediatric heart surgery and cardiology, 90-95% of the children with congenital heart disease reach adult age.This results in an increasing number of adults or "grown-ups" with congenital heart disease (ACHD or GUCH patients) that require special health care organization and training programmes. Long term complications of these GUCH patients and optimum treatment strategies are still poorly known. The aim of this registry is to collect quantitative and qualitative data regarding GUCH patients treated in specialised centres in Switzerland.
NCT05817305
The purpose of the study is to investigate the long-term effects of a personalized physical activity program on exercise capacity and quality of life in patients with stable cardiovascular disease. The analysis also intends to evaluate the prognostic value of cardiovascular function estimated through a walking test (1km Treadmill Walking Test, 1k-TWT) in relation to survival, hospitalization, and medical costs. The program considers clinical, socio-economic, and behavioural aspects, psychological support, and risk factor control. Patients receive indications for carrying out a home training program based on the performance of moderate-intensity aerobic activity at least 3-4 days a week for at least 30-60 minutes a day. All patients are also encouraged to improve their daily habits by preferring a more active lifestyle both at home and at work.
