Angina

Angina is a condition where a person experiences chest pain and discomfort due to a lack of oxygenated blood to the heart muscle. This is usually caused by a build-up of plaque in the arteries, leading to narrowing and hardening of the arteries. This can make it difficult for the heart to pump enough blood and oxygen to the heart muscle, resulting in chest pain and other symptoms. Angina can be classified into two main types: stable angina and unstable angina. Stable angina is typically caused by physical activity or stress and tends to be relieved with rest or medication. Unstable angina is a more serious condition that can lead to a heart attack if not treated quickly. Symptoms of angina can include chest pain, tightness, pressure, or burning in the chest, neck, and arms, as well as tiredness, dizziness, and shortness of breath. Treatment for angina depends on the type and severity of the condition, but may include lifestyle changes, medications, and in some cases, surgery.
