Study Notes
Coronary artery disease (CAD)
- Atherosclerosis is the primary contributor to CAD.
- Endothelial injury and inflammation are the key factors involved in atherosclerosis development.
Angina pectoris
- Angina pectoris is chest pain caused by myocardial oxygen demand exceeding supply.
Left-sided heart failure
- Pulmonary congestion is the most common symptom of left-sided heart failure.
Right ventricle
- The primary function of the right ventricle is to pump blood to the lungs.
Low Intensity Exercise
- Slow walking is considered a low-intensity exercise (1-3 METs).
Exercise and Blood Pressure
- A blood pressure increase of more than 220 mmHg systolic during exercise is an exaggerated response.
- A drop in systolic blood pressure greater than 10 mmHg during exercise may indicate poor cardiac output.
Ejection Fraction (EF)
- A healthy ejection fraction is generally considered to be between 50-70%.
Neurohormonal Activation in Heart Failure
- SNS (Sympathetic Nervous System) and RAAS (Renin-Angiotensin-Aldosterone System) activation increase the workload on the heart.
Types of Heart Failure
- Systolic Heart Failure (HFrEF) is characterized by a reduced ejection fraction.
Cardiac Rehabilitation Monitoring
- Rate of Perceived Exertion (RPE) scale is the best method for monitoring exercise intensity in patients on beta-blockers.
Exercise Intensity and RPE Range
- The target RPE range for moderate-intensity exercise in patients with cardiovascular disease is 6-9.
NYHA Classification of Heart Failure
- Class I heart failure is characterized by no limitation of physical activity.
Right-sided Heart Failure
- A heart failure patient with jugular venous distention is likely experiencing right-sided heart failure.
Cardiac Rehabilitation Phase II
- The typical intensity for aerobic exercise in Cardiac Rehabilitation Phase II is 40-70% of VO2 max.
Exercise Intolerance
- Sudden decrease in respiratory rate is not a common indicator of exercise intolerance.
Diastolic Blood Pressure During Exercise
- Diastolic blood pressure slightly increases or remains unchanged during moderate aerobic exercise in a healthy individual.
Breathing Exercises for Heart Failure
- Diaphragmatic breathing is the most recommended breathing exercise for chronic heart failure.
Function of the Aortic Valve
- The primary function of the aortic valve is to prevent backflow into the left ventricle.
Responding to Palpitations During Rehabilitation
- If a patient experiences palpitations during a rehabilitation session, immediately stop exercise, assess vital signs and reassess the situation.
