Abstract:
Initial treatment of elderly hypertensive patients with an angiotensin-converting enzyme inhibitor is currently discouraged due to such patients' typical low-renin profile. To validate this principle, we studied 38 elderly males (aged ≥ 65 years) with mild to moderate hypertension, comparing hemodynamic responses to and subjective impressions of enalapril or hydrochlorothiazide (HCTZ). After gradual withdrawal of existing antihypertensive therapy and a four-week, single-blind placebo period, each patient was randomized in a double-blind fashion to receive either enalapril 10-20 mg/d or HCTZ 12.5-25 mg/d for two to four weeks. Combination therapy with both agents was employed if either alone failed to reduce seated diastolic BP to ≤ 90 mm Hg. Equivalent proportions of patients receiving enalapril or HCTZ (8 of 19 and 10 of 19, respectively; p = ns) responded with significant reductions in systolic and diastolic BP in seated and standing positions. Combination therapy was most effective in patients receiving HCTZ prior to enalapril. In patients receiving enalapril before HCTZ, BP changes were minimal. No adverse effects were observed in the enalapril group but occurred in an equivalent fraction of patients in the other groups (4 of 10 HCTZ alone, 6 of 20 enalapril + HCTZ; p = ns). We conclude that enalapril may be considered a reasonable monotherapeutic antihypertensive agent in some elderly patients. Combination with HCTZ is beneficial in patients who fail to respond adequately to HCTZ alone.
