Angina is a type of chest pain or discomfort that occurs when the heart muscle (myocardium) does not receive enough oxygen-rich blood.


Types:


1. Stable angina (predictable, triggered by exertion)

2. Unstable angina (sudden, unpredictable, may signal a heart attack)

3. Variant angina (caused by coronary artery spasm)

4. Microvascular angina (caused by small vessel disease)


Causes:


1. Coronary artery disease (narrowing or blockage of arteries)

2. Heart valve problems

3. Heart failure

4. Cardiomyopathy (heart muscle disease)

5. Anemia or low blood pressure


Symptoms:


1. Chest pain or discomfort (pressure, squeezing, or tightness)

2. Pain or discomfort in arms, back, neck, jaw, or stomach

3. Shortness of breath

4. Fatigue

5. Dizziness or lightheadedness


Diagnosis:


1. Electrocardiogram (ECG or EKG)

2. Stress test (exercise or pharmacological)

3. Echocardiogram

4. Coronary angiography

5. Blood tests (e.g., troponin, creatine kinase)


Treatment:


1. Medications (e.g., nitrates, beta blockers, ACE inhibitors)

2. Lifestyle changes (e.g., exercise, diet, stress management)

3. Coronary artery bypass grafting (CABG)

4. Percutaneous coronary intervention (PCI)

5. Cardiac rehabilitation


Complications:


1. Heart attack (myocardial infarction)

2. Heart failure

3. Arrhythmias or abnormal heart rhythms

4. Cardiac arrest

5. Death
