High Blood Pressure is also known as hypertension. Its presence is seriously risk factor for elderly. It is dangerous because it reduced blood flow to vital organs and increases the risk of heart attack, heart failure, stroke and renal failure. Kidney damage may be a cause of high blood pressure. High blood pressure adds to the workload of heart and is associated with an increased risk of coronary heart disease. Two methods of measuring pressure of blood: (1) systolic pressure, which measures the force exerted when the heart beats and send blood into the arteries. (2) diastolic pressure, denotes the pressure in the arties when the heart rests between beats. Cardiovascular risk is associated with both syatolicand diastolic hypertension. High blood pressure among elderly is categorized as either isolated systolic hypertension or combined systolic-diastolic hypertension. Isolated systolic is associated with a loss of arterial elasticity and a rigid aorta. Elevated diastolic pressure is a prevalent condition and a strong risk factor for cardiovascular disease. Deficiency of potassium, calcium and magnesium may contribute to high blood pressure. Reduce salt intake is a strong evidence for lowering high blood pressure among humans. Vegetarian diets have also been linked to lower blood pressure.
