Study Notes
Cardiac Rehabilitation Physiology
Definition and Goals
- Cardiac rehabilitation is a medically supervised program designed to improve cardiovascular health in patients with heart disease or heart failure.
- Goals:
- Improve exercise tolerance and functional capacity
- Enhance overall health and well-being
- Reduce symptoms and risk factors
- Improve psychological well-being and quality of life
Physiological Response to Exercise
-
Cardiovascular Response:
- Increased heart rate and cardiac output
- Enhanced stroke volume and ejection fraction
- Improved vasodilation and decreased peripheral resistance
-
Respiratory Response:
- Increased ventilation and oxygen uptake
- Enhanced gas exchange and diffusion
-
Metabolic Response:
- Increased glucose and fatty acid oxidation
- Enhanced mitochondrial function and ATP production
Adaptations to Exercise Training
-
Cardiovascular Adaptations:
- Increased myocardial thickness and contractility
- Enhanced coronary blood flow and vasodilation
- Improved cardiac function and reduced cardiac workload
-
Muscular Adaptations:
- Increased muscle fiber size and strength
- Enhanced mitochondrial function and oxidative capacity
- Improved muscle endurance and fatigue resistance
-
Neurohormonal Adaptations:
- Reduced sympathetic nervous system activity
- Enhanced parasympathetic nervous system activity
- Improved baroreflex sensitivity and blood pressure regulation
Physiological Benefits of Cardiac Rehabilitation
-
Improved Exercise Tolerance:
- Increased peak oxygen uptake (VO2peak)
- Enhanced exercise duration and intensity
-
Reduced Symptoms:
- Decreased dyspnea, fatigue, and angina
- Improved overall health-related quality of life
-
Reduced Morbidity and Mortality:
- Decreased hospitalizations and readmissions
- Improved survival rates and reduced cardiac mortality
