In this condition, the impairment of arterial blood circulation leads to insufficient blood supply to the myocardium during both rest and exercise, resulting in symptoms such as angina pectoris, dyspnea, and fatigue. Patients, particularly due to their fear of experiencing angina pectoris, tend to adopt a sedentary lifestyle. This situation contributes to exercise intolerance and a reduction in exercise capacity among individuals with CAD. A review of the literature reveals a lack of studies investigating upper and lower extremity exercise capacity and the physiological responses during exercise testing in patients with CAD. Therefore, the aim of this study is to compare arterial stiffness, muscle oxygenation, respiratory muscle fatigue, energy expenditure, perceived dyspnea, and fatigue during upper and lower extremity exercise testing in patients with coronary artery disease.', 'detailedDescription': 'As a consequence of atherosclerosis progresses with aging, the lumen of the arteries narrows and the arterial wall thickens. In patients with coronary artery disease, this process impairs arterial blood flow, resulting in insufficient blood supply to the myocardium. Consequently, due to the inability to meet the oxygen demands of the heart muscle both at rest and during exercise, patients experience symptoms such as angina pectoris, dyspnea, and fatigue. Particularly, fear of developing angina pectoris during physical activity leads patients to develop kinesiophobia and adopt a sedentary lifestyle. This condition further reduces their exercise capacity. In the literature, several studies have assessed the exercise capacity of these patients; however, these studies have predominantly utilized treadmill or cycle ergometers to evaluate lower extremity exercise capacity, and no study has been found that specifically investigates upper extremity exercise capacity. Considering that the upper extremities are used more frequently than the lower extremities during daily living activities, it is of particular importance to evaluate the upper extremity exercise capacity of patients. Moreover, upper extremity exercise testing provides an alternative means of assessment for patients with coronary artery disease who are unable to participate in lower extremity exercise tests due to neurological, vascular, or orthopedic problems. Compared to the lower extremities, the active muscle groups engaged during upper extremity exercise testing are smaller, which leads to lower metabolic demand and reduced peak oxygen consumption. This results in a lower cardiopulmonary workload during the exercise test. Therefore, it is necessary to investigate and compare upper and lower extremity exercise capacities, as well as the physiological responses elicited during exercise testing, in patients with coronary artery disease.\n\nThe primary aim of the study is to compare upper and lower extremity exercise capacities and arterial stiffness levels during exercise testing in patients with coronary artery disease.\n\nThe secondary aim of the study is to evaluate muscle oxygenation, energy expenditure, and the perception of dyspnea and fatigue during upper and lower extremity exercise testing in patients with coronary artery disease.\n\nThe primary outcomes are upper and lower maximal exercise capacities (Cardiopulmonary exercise tests) and arterial stiffness during cardiopulmonary exercise tests (Arteriograph) device).\n\nSecondary outcomes are muscle oxygenation (Near-infrared spectroscopy) device, respiratory muscle fatigue (mouth pressure device), energy consumption (multi sensor activity device), the perception of dyspnea (Modified Borg Scale (MBS)) and fatigue (MBS).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': '30 patients diagnosed with coronary artery disease will be recruited.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adults aged 18-85 with coronary artery disease diagnosed by conventional or CT angiography\n* Clinically stable\n* Willing to participate\n\nExclusion Criteria:\n\n* Heart failure diagnosis\n* Moderate/severe valvular heart disease\n* Orthopedic, neurological, or pulmonary conditions limiting exercise testing/capacity\n* Contraindications per ACSM guidelines\n* Prior coronary artery bypass graft surgery'}, 'identificationModule': {'nctId': 'NCT07148518', 'briefTitle': 'Comparison of Upper and Lower Limb Maximal Exercise Capacities and Arterial Stiffness in Patients With CAD', 'organization': {'class': 'OTHER', 'fullName': 'Gazi University'}, 'officialTitle': 'Comparison of Upper and Lower Limb Maximal Exercise Capacities, Arterial Stiffness, Muscle Oxygenation and Energy Consumption During Tests in Patients With Coronary Artery Disease', 'orgStudyIdInfo': {'id': 'Gazi University 76'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Lower Extremity Group', 'description': 'The first test is the cardiopulmonary exercise test (CPET), which evaluates the maximal exercise capacity of the lower extremities and will be performed on a treadmill.
