Learning objectives
- Explain angina and emergency discomfort.
- Explain risk assessment and restoring flow.
Angina and emergency discomfort
Symptoms can include chest pressure, tightness, or discomfort spreading to the neck, jaw, shoulder, or arm. Breathlessness and unusual fatigue may occur; some people have no warning symptoms. Symptoms during activity may improve with rest. Persistent discomfort or discomfort at rest needs emergency attention. Reduced circulation can also contribute to heart failure or abnormal rhythms, so the significance goes beyond discomfort alone. Evaluation combines history, examination, and selected tests.
Risk assessment and restoring flow
Evaluation combines history, examination, and selected tests. Blood pressure, cholesterol, glucose, and lifestyle help identify risks. Healthy eating, activity, and avoiding tobacco support care. Medicines may address cholesterol, pressure, glucose, or clot formation. Angioplasty opens a narrowed artery; bypass surgery creates a route around an obstruction. Cardiac rehabilitation supports recovery and healthier habits. Choices depend on the affected vessels and individual clinical circumstances. Coronary arteries supply oxygen-rich blood to heart muscle.
Key concepts
- Plaque and the heart’s blood supply
- Coronary arteries supply oxygen-rich blood to heart muscle.
- Large arteries and small vessels
- Coronary disease is not limited to one completely blocked artery.
- Angina and emergency discomfort
- Symptoms can include chest pressure, tightness, or discomfort spreading to the neck, jaw, shoulder, or arm.
- Risk assessment and restoring flow
- Evaluation combines history, examination, and selected tests.
