¿Existe alguna diferencia entre los inhibidores de la enzima convertidora y los antagonistas del receptor de angiotensina para la insuficiencia cardiaca?

Angiotensin receptor blockers are usually considered as equivalent to angiotensin converting enzyme inhibitors for patients with heart failure and low-ejection fraction. Some guidelines even recommend the former as first line treatment given their better adverse effects profile. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified four systematic reviews including eight pertinent randomized controlled trials. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded angiotensin receptor blockers and angiotensin converting enzyme inhibitors probably have a similar effect on mortality, and they might be equivalent in reducing hospitalization risk too. Treatment withdrawal due to adverse effects is probably lower with angiotensin receptor blockers than with angiotensin converting enzyme inhibitors.
