Study Notes
Angina Pectoris
- Characterized by chest pain or discomfort, often described as pressure, squeezing, or heaviness.
- Caused primarily by reduced blood flow to the heart muscle, usually due to coronary artery disease.
- Pain typically eases with rest or the use of nitroglycerin; this highlights its ischemic nature.
- Main risk includes the potential progression to myocardial infarction or heart attack.
- Pain is commonly located in the chest, but may also radiate to shoulders, neck, arms, or jaw.
Congestive Heart Failure (CHF)
- Main characteristic involves the heart's inability to pump effectively, leading to insufficient blood supply to meet the body's needs.
- Causes include coronary artery disease, hypertension, heart valve disease, and prior heart attacks.
- CHF results in reduced cardiac output, impairing the heart’s ability to deliver adequate blood to peripheral tissues.
- Compensatory responses include increased heart rate, enlargement of the heart chambers, and the release of hormones like norepinephrine and aldosterone to maintain blood flow.
- Remodeling of the heart occurs due to prolonged stress, leading to structural changes that further affect heart function and efficiency.
