Study Notes
Myocardial Ischemia
- Occurs when the heart muscle doesn't receive enough oxygen-rich blood.
- Caused by:
- Increased oxygen demand: During exercise, stress, or even eating heavy meals.
- Reduced oxygen supply: Blocked or narrowed coronary arteries due to clots (thrombus) or atherosclerosis (plaque buildup).
Angina Pectoris
- Chest pain or discomfort resulting from myocardial ischemia.
- A symptom signaling the heart muscle isn't receiving enough oxygen.
- Caused by a blocked or narrowed artery, making it difficult for the heart to get enough oxygen.
- Typically felt behind the breastbone and can radiate to the arms, neck, or back.
Types of Angina
- Stable Angina:
- Pain occurs during physical activity or stress.
- Relieved with rest.
- Unstable Angina:
- More severe pain, potentially occurring even at rest.
- May not be relieved with rest or nitroglycerin.
- Variant Angina:
- Caused by spasms in the coronary artery.
- Chest pain often occurs at rest.
- Silent Ischemia:
- No symptoms, despite the heart experiencing a lack of oxygen.
- Often seen in people with diabetes.
