Systolic pressure rises with age, but diastolic pressure, rises with age until 50 years, and then falls, coinciding with the same time cardiovascular disease incidence rises. The prevalence of systolic hypertension is high in those over the age of 50 years, and accounts for more than 80% of cases of hypertension in those over 70 years of age. In the elderly over 60 years of age with hypertension about 65% of them are seen to suffer from isolated systolic hypertension (ISH). ISH manifests, as increased arterial stiffness in the middle-aged and elderly population, and due to its increased risk for vascular events and stroke, needs to be controlled. Since blood pressure is a product of cardiac output and total peripheral resistance, increase in any or both will cause ISH.
