Hypertension and raised serum lipids

About 30",, of patients seen in our lipid clinic during 1976 had raised blood pressure, and many patients attending the hypertension clinic have hyperlipidaemia. This apparent association between hypertension and hyperlipidaemia could have arisen because hypertensives tend to have lipid concentrations measured more frequently than people with no risk factors for vascular disease, or might have been due to treatment. We examined the association further by studying fasting lipid, glucose, and insulin concentrations in untreated hypertensives and in controls.
