Angina is a type of chest pain or discomfort that you experience when your heart muscle is not receiving enough blood flow. The oxygen that your blood carries is essential for your heart muscle.
Your chest may feel compressed or tight during angina. Indigestion could be the sensation. You might also experience pain in your back, neck, jaw, shoulders, and arms. The most prevalent kind of heart illness, coronary artery disease (CAD), manifests as angina. When plaque, a sticky substance, accumulates in the arteries supplying blood to the heart, it causes CAD by decreasing blood flow.
Angina comes in three different forms:
Angina is most frequently stable. When the heart is working harder than usual, it occurs. The pattern of stable angina is predictable. The commonest remedies include rest and medication.
The most serious type of angina is unstable. It is unpredictable and can occur without any effort on your part. With rest or medication, it does not go away. It is a warning sign that a heart attack might occur shortly.
Rare is variant angina. It takes place when you’re sleeping. Drugs can be helpful.
Not every discomfort or chest pain is angina. You should visit your doctor if you experience chest pain.
