Area of Science:

  • Cardiovascular Medicine
  • Pharmacology
  • Genetics

Background:

  • Endothelial dysfunction is a key factor in cardiovascular disease.
  • Angiotensin-converting enzyme (ACE) inhibitors are used to manage cardiovascular conditions.
  • Different ACE inhibitors may have varying effects on endothelial function.

Purpose of the Study:

  • To compare the efficacy of quinapril with other vasoactive substances in improving endothelial function.
  • To investigate the impact of genetic variations (ACE-ID and ACE-II genotypes) on treatment response.
  • To explore differential effects of ACE inhibitors on vascular tissue.

Main Methods:

  • The Brachial Artery Normalization of Forearm Function (BANFF) trial assessed flow-mediated brachial artery dilation.

  • Patients with coronary artery disease received quinapril, enalapril, losartan, or amlodipine.
  • Genetic analysis identified ACE insertion/deletion (I/D) polymorphisms.

    • Main Results:

    • Only quinapril significantly improved brachial artery dilation.
    • Enalapril, losartan, and amlodipine did not show significant improvements.
    • Quinapril demonstrated a highly significant effect in patients with ACE-ID or ACE-II genotypes.

    Conclusions:

    • Quinapril effectively improves endothelial function in coronary artery disease patients.
    • Genetic predisposition influences the effectiveness of quinapril.
    • Further research (QUO VADIS trial) is needed to differentiate ACE inhibitors based on vascular effects.
