As a medical professional with expertise in cardiology, I can explain the various factors that can lead to insufficient blood flow to the heart. This condition, also known as ischemia, can result from several causes:
1. Atherosclerosis: The most common cause of insufficient blood flow to the heart is the buildup of plaque in the coronary arteries. This plaque, which is made up of fat, cholesterol, and other substances, can harden and narrow the arteries, reducing blood flow.
2. Coronary artery spasm: Sometimes, the arteries can suddenly constrict or spasm, which can temporarily reduce blood flow to the heart muscle.
3. Blood clots: A clot can form in a coronary artery, blocking blood flow. This is a serious condition known as a heart attack or myocardial infarction.
4. Anemia: A decrease in the number of red blood cells or their ability to carry oxygen can also lead to reduced blood flow to the heart.
5. Heart failure: When the heart is not able to pump effectively, it can lead to a decrease in the amount of blood reaching the heart muscle.
6. Shock: Severe conditions like septic shock or cardiogenic shock can lead to a drop in blood pressure, which can reduce blood flow to the heart.
7.
Congenital heart defects: Some people are born with heart defects that can affect blood flow.
8.
Vasculitis: Inflammation of the blood vessels can also lead to reduced blood flow.
9.
External compression: In rare cases, pressure from an external source, such as a tumor, can compress a coronary artery and reduce blood flow.
10.
Drugs or medical conditions: Certain medications or conditions can affect the heart's function or the blood's ability to clot, which can impact blood flow.

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).
