Active clinical trials for "Coronary Artery Disease"

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.

To determine the effect of exercise training on cardiac outcomes in coronary artery disease patients after Stenting. There is a need to develop strategies, not only to prevent restenosis but also to improve patients' functional status and perception of well-being. In particular, it is not well defined whether exercise training can reduce the restenosis rate and improve the outcome after PCI.

The purpose of this study is to determine if performed force measurements yield a different recommended weight lifted during the sternotomy healing process than the traditional gold standard of 5 pounds. A secondary endpoint data obtained will be scores from the pre and post-activity questionnaires.

The goal of this observational study is to learn about the factors which determine how well ventricular tachycardia (VT) is tolerated. The main questions it aims to answer are: What impact does coronary artery disease have on the ability for a patient to tolerate VT? Does treatment of coronary artery disease with stents improve the tolerability of VT? Participants who are undergoing a clinically indicated coronary angiogram or coronary angioplasty procedure will have measurements of blood pressure, coronary pressure and coronary flow made during pacing at a range of heart rates.

To determine the effects of exercise training on ankle-brachial index and Quality of Life in coronary artery disease patients after stenting. There is a need to develop strategies, not only to prevent restenosis but also to improve patients' functional status and perception of well-being. In particular, it is not well defined whether exercise training can reduce the restenosis rate and improve the outcome after percutaneous intervention (PCI), and its effects on the Ankle-brachial index are not yet well known.

Prospective, multi-center, single arm study designed to evaluate the safety and performance of the Shockwave Coronary Rx Lithoplasty® System to treat calcified lesions in the coronary arteries for the purpose of enhancing the placement of stents and reducing the ultimate residual stenosis. Patients will be followed through discharge and at 30 and 180 days.

Patients with diabetes mellitus (DM) are at increased risk of atherothrombotic events. Importantly, DM is a key risk factor for the development of chronic kidney disease (CKD), which further enhances atherothrombotic risk. Clopidogrel is the most widely used platelet P2Y12 receptor inhibitor. However, despite its clinical benefit, patients with DM and CKD frequently experience recurrent atherothrombotic events. Ticagrelor is an oral, reversible, non-competitive P2Y12 receptor inhibitor with more potent and consistent platelet inhibition than clopidogrel. In large-scale clinical investigation, ticagrelor significantly reduced ischemic events to a greater extent than clopidogrel, a finding that was consistent also among DM patients. To date there has been no analysis on the efficacy of ticagrelor in DM patients according to CKD status. Moreover, although pharmacodynamic (PD) studies showed enhanced platelet inhibition associated with ticagrelor, it is unknown how this may be affected by CKD status. Ultimately, how PK/PD profiles of different ticagrelor dosing regimens may be affected by DM and CKD status is also unknown. The proposed study is aimed to show the impact of CKD status among patients with DM and coronary artery disease) CAD on PD and PK profiles of ticagrelor used at 2 doses (90mg bid and 60mg bid) in the setting of a prospective, randomized, cross-over trial.

The EVOLVE Short DAPT Study is a prospective, multicenter, single-arm study designed to assess the safety of 3-month DAPT in subjects at high risk for bleeding undergoing PCI with a SYNERGY Stent System.

It is not uncommon that patients requiring dual antiplatelet therapy (DAPT) also need to be treated with oral anticoagulant therapy, such as those with atrial fibrillation (AF). Warfarin and clopidogrel are still the most widely utilized oral anticoagulant and P2Y12 receptor inhibitor, respectively. However, over the past years, several non-vitamin K antagonist oral anticoagulants, including edoxaban, have been studied in the setting of AF showing encouraging safety and efficacy profiles as compared with warfarin. However, the effects of edoxaban in combination with DAPT in the setting of patients with coronary artery disease (CAD) are unexplored. Moreover, the role of edoxaban as part of a dual antithrombotic treatment strategy, including clopidogrel and stopping aspirin, represents another important area of clinical interest. This investigation is a prospective, randomized, parallel-design, open label, pharmacodynamic study conducted in patients with CAD on DAPT with aspirin and clopidogrel testing two different edoxaban dosing regimens in addition to DAPT with aspirin and clopidogrel, as well as in combination with clopidogrel only (after stopping aspirin).

The sample of this randomized controlled trial was obtained in the Cardiovascular Prevention and Rehabilitation Unit, of the Hospital Centre of Porto, Santo Antonio General Hospital. The target population was individuals who have completed the training phase of cardiovascular rehabilitation program, volunteers and referenced by the responsible for the service. This study has as main objective to analyze the influence of a specific exercise program, maintenance phase of cardiovascular rehabilitation , in home care context, for a period of 6 months, using a virtual format (computer and Kinect) or a conventional format (paper manual) in subjects with coronary artery disease. It was intended to analyze the immediate effect of exercise program on body composition and food consumption patterns, functional muscle strength of lower limb, level of physical activity: total volume of activity as well as the profile of this intensity, kyphotic index, balance, cognitive and executive function, as well as in the quality of life. The aim is also to examine the effects, approximately 3 months after the end of the exercise program, in the lipid profile, the level of physical activity: total volume of activity as well as the profile of this intensity and cardiovascular fitness: maximum double product ; metabolic equivalents; and proof and recovery time. The individuals were distributed at random, every 3 individuals, using the capabilities of Microsoft Excel 2010 RANDBETWEEN command, by three groups: the experimental group 1- a cardiovascular rehabilitation program, in home care context, using a computer and Kinect, virtual format, the experimental group 2- in cardiovascular rehabilitation program, in home care context, using a paper-based manual, conventional format, and control group-only subject to education for cardiovascular risk factors. The program defined 3 training sessions per week. The rehabilitation program was oriented by the guidelines for exercise prescription. Participants perform the a program of specific exercises independently and individually, with remote supervision, using communication (phone, email, etc.) and a routine scheduled individual meetings.
