The goal of this study is to test the feasibility and acceptability of an informational website to reduce uncertainty, psychological distress, and caregiver burden among close family members of cardiac arrest patients. The investigators hypothesize that participants who receive access to the website will have lower rates of uncertainty, psychological distress, and caregiver burden at 3 months post-hospital discharge compared to participants who receive usual care.
The treatment of coronary bifurcation lesions continue to remain challenges. Due to the special hemodynamics caused by the special anatomical structure of the coronary bifurcation, it is easy to cause vascular crest displacement and plaque formation. The existing single-stent strategy and double-stent strategy are easy to cause vascular crest offset, stent accumulation, in-stent thrombosis, in-stent restenosis and other poor long-term prognosis. Stent-balloon-stent (Stent-balloon-stent, SBS) technique enables the guide wire to enter the side branch from the mesh at the distal end of the main vascular stent, and the drug balloon is used to dilate the opening of the side branch, so that the opening area of the side branch is more than 5mm².The SBS technique reduces the risk of branch vascular dissection, occlusion, snow shoveling phenomenon, maintain the original state of bifurcated blood vessels to the greatest extent, should have a good impact on the long-term prognosis of patients with coronary bifurcation lesions (CBL). The purpose of this study is to explore the feasibility, safety and effectiveness of SBS technique.
The goal of this study is to learn how long-term use of estrogen affects blood vessels in healthy adults who were assigned male at birth. Participants will: - give one blood draw of 5 mL - have a camera placed under the tongue to take pictures of blood vessels - have 2 laser Doppler microdialysis catheters placed on the forearm to monitor blood vessels before and after local drug infusion Researchers will compare blood vessel function of those who take estrogen supplements to those who do not.
Dietary fat plays a crucial role as a modifiable risk factor influencing both non-fasting lipaemia and vascular reactivity. Notably, the intake of dietary saturated fatty acids (SFAs) has been associated with adverse effects on blood lipid profiles, whereas increased consumption of unsaturated fatty acids (UFAs) has shown potential to improve lipid health. Pomegranate seed oil (PSO) stands out due to its high content of conjugated α-linolenic acids (CLnAs). However, research comparing the impact of these fatty acids on postprandial vascular function, particularly in postmenopausal women, remains limited. A cross-over, single-blind, randomised acute postprandial study will be conducted in 15 healthy postmenopausal women. Participants will be assigned to consume the test meals either a placebo (50 g of mixed fat; 4:0.5:0.5 palm oil: rapeseed oil: safflower oil) or PSO (40 g of mixed fat and 10g of PSO) in random order on 2 separate occasions, with 4-6 weeks between each study visit. The anthropometric, blood pressure, and arterial stiffness, will be taken for each study visit. Blood samples will be collected for the measurement of fasting lipids, glucose, insulin, inflammatory markers, and whole blood culture. The findings from this study will contribute to the evidence base on how consuming meals rich in PSO influence the level of blood lipids as well as other biomarkers for cardiovascular disease.
This clinical trial develops and tests a culturally-appropriate educational program (Indigenous SIPin) for reducing sugar-sweetened beverage consumption in men affiliated with Native American athletics communities. Sugary drinks are drinks like pop, soda, and juice. Increased sugar consumption may lead to an increased risk of chronic diseases, including obesity, diabetes, some types of obesity-related cancers, coronary heart disease, hypertension, and dental decay. A culturally sensitive program may help reduce sugar-sweetened beverage consumption in Native American men
This study examines cardiovascular responses to a brief psychological challenge under laboratory conditions among adult volunteers. The study volunteers are asked to complete two study sessions. In one session, the volunteers are asked to provide demographic and health-related information via questionnaires and an interview. In that session, volunteers would then be asked to undergo evaluations of their body composition, blood pressure, heart rate, and other signs of cardiovascular function and health. Lastly, volunteers would be asked to take part in a brief and challenging psychological task after a period of rest while cardiovascular activity is measured. In the other session, volunteers are asked to undergo magnetic resonance imaging and to complete neuropsychological tests of memory, attention, and processing speed. In addition to these two sessions, volunteers are asked to complete online questionnaires. The study is designed to examine associations between transient changes in cardiovascular activity induced by the psychological task, measures of overall cardiovascular health, and measures of cerebrovascular health measured by magnetic resonance imaging. Study results are expected to provide new information about the relationships between cardiovascular activity changes to psychological challenges and cardiovascular and cerebrovascular health in adults.
The purpose of this research is to determine the effects of a chewing gum containing dietary nitrate to gingival and heart health. Dietary nitrates are commonly found in leafy vegetables and beets. The information learned from the study may help further understand the interconnection of oral health and heart health. The study is looking for individuals who present with mild to moderate gum irritation or bleeding. In the study participants will be randomized into either a group that will use a chewing gum containing dietary nitrate, or use a placebo chewing gum during a three-week period. Participants in the study will have a simple gingival exam, x-rays if needed, and small samples of saliva and blood collected. All participants will also undergo a routine tooth cleaning. Participants will be asked to breathe in a tube to sample the levels of nitric oxide. Finally, participants will have their heart health measured with a device that is like a blood pressure cuff.
The goal of this clinical pilot / feasibility study is to determine the feasibility of conducting a large-scale clinical effectiveness trial of the aktivplan digital intervention in cardiac rehabilitation patients. The main questions this study aims to answer are: - Is it feasible to conduct a large-scale (fully powered) effectiveness trial of the aktivplan digital intervention? - What is the usability, user experience and user acceptance of the aktivplan digital intervention? Patients enrolled in a phase II cardiac rehabilitation programme will be randomly allocated to either the intervention group (aktivplan digital intervention) ot the usual care control group and followed-up for 10 weeks after discharge from cardiac rehabilitation. Patients in the intervention group will be given the aktivplan application (app) on their smartphone. A rehabilitation professional will plan a personalised heart-healthy physical activity plan together with the patient and enter it to the aktivplan app. The patient will be asked to follow their personal physical activity plan for 10 weeks, using the aktivplan app to document completed physical activity sessions. Patients in the control group will receive the usual standard of care without the aktivplan digital intervention. Researchers will analyse information such as the rate of recruitment, participant attrition, data completeness and technical stability of the app to determine the feasibility of conducting a large-scale clinical effectiveness trial.
The purpose of this study is to assess the effects of an 8-week supervised high-intensity interval training (HIIT) program (vs. physical activity recommendations according to current guidelines) on a comprehensive panel of circulating sphingolipids in middle-aged females and males at elevated cardiometabolic risk.
