Management of multiple risk factors for coronary heart disease in patients with hypertension.

Hypertension intervention trials, which have involved mainly the use of diuretics and beta-blockers, have demonstrated a disappointing benefit in terms of reduction of coronary heart disease (CHD). Rather than suggesting that elevated blood pressure and CHD are not causally related, these data suggest that the antihypertensive agents used were not optimal for the management of hypertension and a review of the currently recommended therapies is needed. Major risk factors for CHD, which include increased blood pressure, elevated serum cholesterol levels, and smoking, are highly prevalent in the general population and appear to cluster in patients with hypertension. Therefore the treatment of hypertension demands a multifactorial approach, one that takes into consideration all the risk factors for CHD. Diuretics and beta-blockers adversely affect the serum lipid profile, and this could negate some of the CHD benefit afforded by blood pressure reduction.
