Does the combination of ACE inhibitor and calcium antagonist control hypertension and improve quality of life? The LOMIR-MCT-IL study experience

Abstract

The LOMIR-MCT-IL study was designed to investigate the effects of different antihypertensive drugs on the quality of life (QoL) of men with mild-to-moderate hypertension. This report focuses on the subgroup of patients treated with the combination of the angiotensin converting enzyme (ACE) inhibitor captopril and the calcium antagonist isradipine. The LOMIR-MCT-IL was a double-blind multicenter, placebo-controlled, one-year follow-up study in which 368 hypertensive men, aged 40-65 years, were randomly allocated to receive either isradipine, methyldopa or placebo at three titration levels. If diastolic blood pressure (DBP) remained > 90 mmHg, captopril was added openly. The QoL evaluation introduced a qualitative self-structured subjective measure in addition to prestructured quantitative measures. The quality of life was assessed at baseline, after 6 months and at the end of the study. Methyldopa normalized DBP in 50% of patients when given as monotherapy and an additional 34% with the addition of captopril (84% total). With placebo, 36% normalized DBP and another 39% on addition of captopril (75% total) and, with isradipine, 64% normalized DBP and an additional 26% with added captopril (90% total). Assessment of QoL showed that both the placebo and the isradipine+captopril groups showed significant improvement in semantic memory after antihypertensive treatment. The isradipine+captopril group showed a clear tendency towards lower depression scores, better quality of sleep, better subjective evaluation of QoL and a more positive evaluation of personal life events in comparison to the other groups.(ABSTRACT TRUNCATED AT 250 WORDS)
