Blood pressure is the measure of the force of blood pushing against blood vessel walls. High blood pressure, or hypertension, forces the heart to pump blood harder leading to atherosclerosis and heart failure, states WebMD.

Hypertension is more common in men than women and in blacks than whites. After age 65, black women have the highest incidence of high blood pressure.
