When your blood pressure is measured, it is a measure of how hard the heart has to work to pump the blood. When the arteries become hardened with cholesterol plaque and calcium the heart has to strain to pump blood through them. This makes the blood pressure go abnormally high.
Those whose blood pressure are consistently higher than this norm have high blood pressure or hypertension,which can lead to heart attack, stroke, and kidney failure.
