Blood pressure is the force exerted by the blood against the walls of blood vessels, and the magnitude of this force depends on the cardiac output and the resistance of the blood vessels. When the systolic blood pressure (SBP) which is the pressure as the heart pumps blood around the body is 140 mm Hg or more, or a diastolic blood pressure (DBP) which is the pressure as the heart relaxes and refills with blood, is 90 mm Hg or more, and the individual is taking antihypertensive medication, it is called Hypertension (Madhur, 2014). High blood pressure is a major risk factor for various other illnesses and even death due to several cardiac and vascular diseases. It is assessed that about 54% of strokes, 47% of heart attacks, 75% of hypertensive disease, 25% of other heart disease, 13.5% of all mortality, and 6% of morbidity are linked to Hypertension (Khraim & Pike, 2014). Hypertension affects about 70 million adults in the United States. Only about half (52%) of people with hypertension have their blood pressure under control. Nearly 1 in 3 American adults have prehypertension which means that blood pressure numbers are greater than usual, but not in the high blood pressure range. Hypertension costs the country about $46 billion annually. This comprises the cost of health care services, drugs to treat hypertension, and days of absence from work (CDC, 2015).
