The conventional method of measuring BP in the arm (brachial BP) may miss some cases, as individuals can have normal brachial pressure but elevated central systolic pressure, which is a more critical predictor of cardiovascular events. Lowering BP is a key objective in cardiac rehabilitation programs.\n\nExamining BP responses after a single bout of exercise could help predict how effectively exercise lowers BP over time. There is a well-established reduction in BP, known as post-exercise hypotension (PEH), which occurs after exercise. This drop is typically around 8 to 9 mmHg and is observed in individuals with and without hypertension. However, it may not occur in people with CAD. The reason for this difference is unclear but may relate to individual variability in exercise responses.\n\nNo research has closely examined individual responses to PEH in people with CAD, and it remains unclear whether exercise affects central and brachial BP differently, as some medications do. Additionally, exercise intensity may influence the magnitude of the BP reduction post-exercise. Higher-intensity exercise tends to cause a more significant BP drop, both in hypertensive and non-hypertensive individuals, typically within 20 to 60 minutes post-exercise.\n\nTherefore, the present study aimed to determine the acute effects of combined exercise at different intensities on central and brachial blood pressure in individuals with and without coronary artery disease.\n\nThe key research questions were:\n\n1. Is the BP response of central and brachial arteries to acute combined exercise similar? How does coronary artery disease influence these BP responses? Is there individual variability among people with CAD?\n2. Does high-intensity exercise, compared to moderate-intensity exercise, produce more pronounced changes in BP in the post-acute exercise period?\n\nAll participants were asked to:\n\nComplete two combined exercise sessions - one moderate- and one high-intensity bout. The order of the sessions was randomly assigned, similar to flipping a coin.\n\nBP was measured before and after each acute exercise bout in the laboratory. The researchers compared central and brachial BP responses between exercise intensities (high vs. moderate) and populations (individuals with and without CAD).", "detailedDescription"=>"This study was designed as a randomized cross-over, repeated measures experiment. All participants underwent two combined exercise sessions of varying intensities, specifically high (HIGH) and moderate (MOD), in a randomized sequence (http://www.randomizer.org/). Before the exercise sessions, all participants underwent both cardiopulmonary exercise testing and 1RM testing, followed by a DEXA scan during a subsequent visit to the laboratory. Each participant completed all experimental sessions consistently at the same time of the day, specifically in the mornings, with at least 48h between sessions to reduce diurnal variation. Post-exercise measurements were conducted at 5, 15 and 30 min after exercise. Participants reported to the laboratory in a fasted state (≥ 4h), and refrained from vigorous exercise, vitamin supplements, and foods/beverages containing caffeine and alcohol for at least 12 h preceding each experimental session."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"85 years", "minimumAge"=>"55 years", "healthyVolunteers"=>true, "eligibilityCriteria"=>"Inclusion criteria for the coronary artery disease group:\n\n* Middle-aged and older adults with stable coronary artery disease (over 55 years old)\n\nInclusion criteria for the control group:\n\n* Aged-matched healthy adults free of cardiovascular, respiratory, or metabolic disease and with no more than 2 traditional risk factors.\n* Physically active defined as engaging in exercise at least 3 times per week over the past 6 months\n\nExclusion criteria for both groups:\n\n* Cognitive impairment\n* Pulmonary disease\n* Uncontrolled atrial or ventricular dysrhythmia\n* Disability or mental illness\n* Extra-cardiac disease"}, "identificationModule"=>{"nctId"=>"NCT06617117", "briefTitle"=>"Central Vs Brachial BP, Exercise, and Coronary Artery Disease", "organization"=>{"class"=>"OTHER", "fullName"=>"Egas Moniz - Cooperativa de Ensino Superior, CRL"}, "officialTitle"=>"Dynamic Acute Responses of Different Intensity-dependent Exercises on the Autonomic and Vascular Systems in People with Coronary Artery Disease", "orgStudyIdInfo"=>{"id"=>"BRAVE HEARTS"}}, "armsInterventionsModule"=>{"armGroups"=>[{"type"=>"EXPERIMENTAL", "label"=>"Moderate-intensity combined exercise", "description"=>"A one-hour exercise session of moderate-intensity structured as follows: a warm-up (10 min), aerobic exercise (20 min), followed by a circuit resistance exercise (20 min), concluded with passive stretching cool down (10 min).", "interventionNames"=>["Other: Moderate-intensity combined exercise"]}, {"type"=>"EXPERIMENTAL", "label"=>"High-intensity combined exercise", "description"=>"A one-hour exercise session of high-intensity structured as follows: a warm-up (10 min), aerobic exercise (20 min), followed by a circuit resistance exercise (20 min), concluded with passive stretching cool down (10 min).", "interventionNames"=>["Other: High-intensity combined exercise"]}], "interventions"=>[{"name"=>"High-intensity combined exercise", "type"=>"OTHER", "description"=>"The main part consisted of interval cycling exercise, comprising 5x2 min at the second ventilatory threshold interspersed with 4x2 min at the first ventilatory threshold, followed by 2-min unloading pedalling.
