title: Are angiotensin-converting enzyme inhibitors or angiotensin 2 receptor antagonists effective in heart failure with preserved ejection fraction?
abstract: Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) constitute first line treatment for patients with heart failure with reduced ejection fraction. However, their role in patients with preserved ejection fraction remains controversial. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified five systematic reviews including five randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded ACEI and ARB do not decrease mortality or hospitalization risk in this group of patients.
