ACE-inhibitors and quality of life.

A review of the literature concerning quality of life aspects on ACE-inhibitors in hypertensive patients is given. In the first part of the eighties two prospective multi-center randomised trials were conducted to determine the effect of captopril in comparison to methyldopa or an unselective beta-blocker on the quality of life in patients with mild to moderate hypertension (Hill et al. and Croog et al.). Both studies revealed slight but significant positive effects on indices of quality of life in captopril treated patients compared to those who had methyldopa or an unselective beta-blocker. Later, another ACE-inhibitor, enalapril, has been compared with a selective beta-blocker (Edmonds et al. and Herrick et al.) with respect to side-effects and the quality of life. The measurements of the quality of life tended to favour enalapril, but the differences were small and the over-all tolerability of the two drugs was similar. In conclusion, comparisons with more long standing forms of antihypertensive therapy suggest a slightly more favourable effect of ACE-inhibitors on the quality of life.
