title: Efficacy of combination therapy with angiotensin-converting enzyme inhibitor and calcium channel blocker in hypertension.
abstract: BACKGROUND
  There are few clinical trials that provide evidence to support the hypothesis that combined therapies offer a favorable risk-benefit ratio in the reduction of cardiovascular mortality and morbidity. Combined therapies containing an angiotensin-converting enzyme inhibitor (ACEI) with a calcium channel blocker (CCB) is one of the recommended combinations in the reappraisal of the European Society of Hypertension.
  
  
  METHODS
  The authors have performed a systematic review of the available clinical evidence on the use of combined therapies containing an ACEI with a CCB versus other combinations in the management of arterial hypertension (HT) and in the reduction of cardiovascular morbidity/mortality, according to recommendations of The Cochrane Handbook for Systematic Reviews of Interventions. They identified 122 potentially relevant studies. Of these, 38 included combined therapies in one or both treatment arms. Overall, a total of 12 publications were retrieved from the search and provided data on the effects of the combined therapy with an ACEI and a CCB on cardiovascular mortality/morbidity in patients with HT. Clinical evidence corresponds to three double-blind clinical trials: ASCOT-BPLA, ACCOMPLISH and Syst-EUR.
  
  
  CONCLUSIONS
  The analysis demonstrates the superiority of the combined therapy with ACEI/CCB not only in the overall population included in the studies but also in subsets of patients with a high cardiovascular risk such as diabetes and chronic kidney disease.
