About this trial

This study is intended to investigate the effect of angiotensin receptor blockers (ARBs) on mild-to-moderate aortic stenosis.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Normal left ventricular ejection fraction (i.e. ≥50%)

Systolic blood pressure >110 mmHg

Diastolic blood pressure >70 mmHg

Disqualifiers

More than mild aortic or mitral regurgitation, or mitral stenosis

Current use or documented indication for renin-angiotensin system medication or Aliskiren

Known allergy or intolerance to angiotensin II receptor blockers (ARBs)

Alzheimer, dementia or known non-compliant patient
