How can high blood pressure cause a heart attack?

[ZoeKatsoulis]

High blood pressure progressively leads to hardening of all blood vessels in the body including the coronary arteries that supply the heart muscle. As a consequence, the coronary arteries slowly, become narrowed, limiting the amount of blood flow in the heart. Without oxygen the heart muscle is unable to contract efficiently and suddenly stops its activity, that is heart attack.
