Hypertension, also known as high blood pressure is starting to become a very common cardio vascular diagnosis. Hypertension is classified as a cardiovascular disease caused by elevated blood pressure (Mosby's, 2006, p. 923). Hypertension is more dominant for individuals that have unhealthy lifestyles and have a family history of hypertension. Hypertension is also dominant in individuals that consume more that 5.8 grams of salt per day (Makoff, 2006). Having high blood pressure may cause other health problems if it is not treated. The health problems associated with high blood pressure are dangerous and sometimes fatal. When the blood pressure of a patient rises above 120 over 80 they are medically considered to have high blood pressure (Mosby's, 2006, p. 923).

There are two types of hypertension: essential hypertension and secondary hypertension. Essential hypertension is when there is no specific cause for the increased blood pressure and the condition can not be explained (Brams, 1973, p. 96). Ninety five percent of hypertension cases are classified as essential (Makoff, 2006). Secondary hypertension is when the high blood pressure is a result of another health problem such as kidney disease or certain tumors (Brams, 1973, p. 107). Five percent of hypertension cases are classified as secondary (Makoff, 2006). Essential hypertension is caused by many health factors working together to increase blood pressure. The factors that influence essential hypertension are age, stress, ethnicity, gender, diurnal variations, medications, susceptibility, obesity, salt intake, genetics, and kidney failure (Perry and Potter, 2006, p. 599). Thirty percent of all essential hypertension cases are caused by genetic factors (Makoff, 2006).

Essential and secondary hypertensions are classified by the severity of the high blood pressure. The degrees of severity are "Class I" being mild, "Class II" being moderate, and "Class III" being severe (Brams, 1973, p. 112)....
