Hypertension

ABSTRACT

Approximately one in four adults has hypertension; a prevalence that increases with age and may reach to two out of three adults older than 70 years of age. In the Framingham Heart Study 65-75 of hypertension in the elderly is of the isolated systolic hypertension variety. Hypertension causes a two- to threefold increased risk of atherosclerotic cardiovascular events. Hypertension clusters with dyslipidaemia; insulin resistance; glucose intolerance and obesity in more than 80 of cases.1 The great majority of hypertensives thus have additional cardiovascular risk factors. The global cardiovascular risk; of which hypertension is but one component; is best appreciated by the use of risk charts such as the Framingham Risk Score
