What are the signs and symptoms of angina?

As a domain expert in cardiology, I can provide you with a comprehensive overview of the signs and symptoms of angina. Angina is a type of chest pain that occurs when there is reduced blood flow to the heart muscle, often due to the narrowing of the coronary arteries from atherosclerosis. Angina symptoms include: 1. Chest pain or discomfort, which can feel like a sensation of pressure, squeezing, burning, or fullness. This is often the most recognized symptom of angina and typically occurs in the center or left side of the chest. 2. Pain in your arms, particularly the left arm, neck, jaw, shoulder, or back. This pain can travel from the chest to these areas and is often described as aching or sharp. 3. Nausea and indigestion, which can sometimes be mistaken for gastrointestinal issues. 4. Fatigue, particularly after physical exertion or emotional stress. 5. Shortness of breath, which can occur with or without chest pain. 6. Sweating, which may be a sign of the body's response to the pain and stress. 7. Dizziness or lightheadedness, which can be a result of decreased blood flow to the brain. It's important to note that not everyone with angina will experience all of these symptoms, and the intensity can vary from person to person. Some individuals may have what is known as "silent ischemia," where they have no symptoms despite the reduced blood flow to the heart. If you suspect you are experiencing angina, it is crucial to seek medical attention promptly, as it can be a sign of an increased risk for a heart attack.
