The interventional cardiologist performed 100 interventional procedures using either a new protective device (NPD) or a traditional lead clothing (TLC). The cumulative dose outside the NPD or TLC and the first operator at each height (110cm, 90cm, 50cm, 10cm) was measured. The main indicators of the study are the average X-ray shielding efficiency of the NPD and the TLC at four different heights. The investigators will record all operation information in this study.

NCT ID: NCT05081999 Not yet recruiting - Clinical trials for Coronary Artery Disease

De-Adoption of Beta-Blockers in Patients With Stable Ischemic Heart Disease

Start date: June 1, 2022
Phase: Phase 4
Study type: Interventional

Patients with heart disease are often prescribed many medications and these patients may experience drug interactions or negative drug related side effects. With newer medications and treatments available, it is not well known whether older drugs, such as beta-blockers, are still an effective and safe option for treating heart disease. Some evidence suggests beta-blockers should be continued, whereas other evidence suggests beta-blockers might cause unnecessary harm. The study hopes to determine whether continuation or discontinuation of beta-blockers will affect long term cardiovascular outcomes. The study investigators will also examine how beta-blockers continuation or discontinuation affects several quality of life measures.

NCT ID: NCT05075317 Not yet recruiting - Clinical trials for Coronary Artery Disease

Time Restricted Eating and Cardiac Rehabilitation

Start date: November 1, 2021
Phase: N/A
Study type: Interventional

Time restricted eating (TRE) is a form of intermittent fasting where individuals consume ad libitum energy intake within a set window of time, commonly 8 hours, which induces a fasting window of 16 hours per day (i.e., 16:8 TRE). TRE could be an effective addition to cardiac rehabilitation as it has demonstrated cardiovascular health benefits and potential for synergy when combined with exercise training. This study will be a two site (Toronto Rehabilitation Institute and Toronto Western Hospital), 2-arm, parallel group, randomized feasibility trial of cardiac rehabilitation alone or cardiac rehabilitation plus 16:8 TRE. Men and women who are referred through the standard clinical pathways and eligible for either outpatient cardiac rehabilitation program for coronary artery disease and are willing to accept random assignment and complete the study assessments will be enrolled. Both groups will receive the standard, multi-dimensional cardiac rehabilitation program consisting of physician-directed risk factor management, an individualized exercise prescription, and virtual education. All participants will receive an assessment with a registered dietitian and individualized recommendations for a heart healthy diet. During the consultation with the registered dietitian, the TRE group participants will also be counselled to restrict their eating to between 11 am and 7 pm and consume no calories outside of those hours during the program starting the evening of the consultation. The primary outcome is feasibility measured by daily adherence to the 16-hour fast which will be tracked with two daily text messages for the 16 weeks of the cardiac rehabilitation program. The safety outcomes that will be compared between groups include re-hospitalization, death, angina, and nutritional impact symptoms. Before randomization and after completion of the program the following preliminary efficacy outcomes will be assessed: 1) VO2peak; 2) total body and truncal fat, lean mass; 3) metabolic markers: fasted glucose, insulin, hemoglobin A1c, blood pressure and waist circumference. The investigators hypothesize that cardiac rehabilitation and TRE will be feasible, safe, and provide added cardiovascular health benefits compared to cardiac rehabilitation alone.

Effectiveness of a Motivated, Action-based Intervention on Health Outcomes of Coronary Heart Disease Patients

Start date: August 15, 2021
Phase: N/A
Study type: Interventional

Coronary heart disease (CHD), the major group of cardiovascular disorders, is the leading cause of cardiac-associated mortality, causing >9 million death in 2016. American Heart Association (AHA) and the American College of Cardiology Foundation (ACCF) recognized that lifestyle modification including physical activity is the class one-level recommendation for secondary prevention and risk reduction therapy for patients with CHD. The assessment of physical activity and confidence in performing exercise for patients with CHD will help healthcare professionals to develop and implement the appropriate intervention to enhance patients' confidence in performing exercise and physical activity to promote and maintain their health. With the increasing morbidity and mortality from CHD, especially in low and middle-income countries, secondary prevention including exercise-based cardiac rehabilitation (CR) plays an important role to improve the prognosis of CHD patients. High prevalence of physical inactivity, unhealthy dietary practices, poor control of blood glucose, blood pressure (BP), blood lipid, and body weight (BW) was found among CHD patients in the world as well as in Sri Lanka. Therefore, it is important to design and implement an appropriate intervention to improve the physical activity level, exercise self-efficacy, and cardiovascular risk factors in CHD patients in Sri Lanka. This study aims to develop and examine a culturally specific motivated, action-based intervention for improving physical activity level, exercise self-efficacy, and cardiovascular risk factors of CHD patients in Sri Lanka. The participants will be patients who admitted to the coronary care unit (CCU) and medical wards of the Teaching Hospital Batticaloa, Sri Lanka with CHD for the first time confirmed by electrocardiogram with aged 18 years or above, able to reads and speak Tamil, able to attend clinic follow-up, obtain a medical clearance from a cardiologist to perform the exercise and, able to understand and give informed consent. The medical records of the CHD patients will be reviewed to screen for their eligibility. In addition, the cardiologist of the participants will be consulted for their suitability to perform the exercise of the intervention. The purpose of the study, the data collection procedures, the potential risk and benefits, the maintenance of confidentiality, and the voluntary basis of participation will be clearly explained to the participants, and informed written consent will be obtained before data collection. Ethical approval was obtained from The Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee and Ethics Review Committee, Faculty of Health Care-sciences, Eastern University, Sri Lanka. The Statistical Package for Social Science version 22.0 software (SPSS 22.0) will be used to analyze the data and the p-value less than 0.5 will be considered as significant. This study will provide evidence on the effectiveness of a motivated, action-based intervention on the physical activity level, cardiovascular risk factors, and exercise self-efficacy of CHD patients in Sri Lanka. Findings from this study could be useful to promote healthy lifestyle behaviors in CHD patients in a low-resource setting. Furthermore, this study will provide information on which level this intervention could be applied and possible constraints that hinder the outcomes of the results.
