Assessment of absolute cardiovascular risk is a rational method of managing
hypertension. General practitioners and practice nurses were asked to esti
mate absolute risk in a group of elderly hypertensive patients during clini
cal practice. Risk was correctly estimated in 21% of patients, underestimat
ed in 63% of patients, and overestimated in 16% of patients. Unless primary
health care professionals use cardiovascular risk charts or tables, treatm
ent decisions in primary care may not be made against realistic estimates o
f patients' susceptibility to cardiovascular disease.
