What is dangerous percent artery blockage?

Atherosclerosis, or the buildup of plaque in the arteries, can lead to coronary artery disease (CAD) when it affects the arteries that supply blood to the heart. Plaque is made up of cholesterol, fat, calcium, and other substances. As plaque builds up, it can narrow the arteries and reduce blood flow to the heart.

The severity of artery blockage is typically measured by the percentage of narrowing that has occurred. A blockage of 50% or more is considered significant and can increase the risk of a heart attack. Blockages of 70% or more are considered severe and can cause chest pain, shortness of breath, and other symptoms of CAD.

It is important to note that even a small amount of plaque buildup can increase the risk of a heart attack, especially in people with other risk factors such as high blood pressure, high cholesterol, obesity, diabetes, and smoking.

If you have any symptoms of CAD, it is important to see your doctor immediately. Treatment for CAD can include lifestyle changes, medication, and surgery.
