As a cardiovascular health specialist, I can explain that an angina attack is typically caused by reduced blood flow to the heart muscle. The heart muscle requires a steady supply of oxygen-rich blood to function properly. When this supply is insufficient, it results in a condition known as ischemia. The primary cause of this reduced blood flow is coronary artery disease (CAD), which is characterized by the narrowing of the coronary arteries due to plaque buildup. This plaque, often made up of fat, cholesterol, and other substances, can restrict blood flow, leading to angina. read more >>

Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn't getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD).read more >>
