There has been a continuous evolution in hypertensive therapy during the last 30 years. Now, physicians have access to more than 40 agents for treating this widespread condition. Large-scale clinical trials have established that lowering blood pressure in patients with mild to moderate diastolic hypertension results in a decreased incidence of stroke and, to a lesser extent, a reduction in incidence of coronary heart disease [MacMahon SW, Cutler JA, Furberg CD, et al: Prog Cardiovasc Dis 1986; 29 (suppl 1): 99-118]. Even so, the decrease in overall mortality rate is not consistent. Although hypertension occurs with increasing frequency in those over 60 years of age, patients in this age group represent less than 12 percent of the subjects in large trials. Currently, stepped-care is the recommended approach for managing hypertension in patients of all ages. However, the availability of a variety of agents for initial therapy, all with approximately equal efficacy but differing side-effect profiles, calls such an approach into question.
