Left Atrial Remodelling in Hypertension: Effects of Ramipril or Irbesartan - Full Text View

Purpose

Aim of the study is to compare in hypertensive patients the effect of one year therapy with ACE-inhibitor (RAMIPRIL) or angiotensin II receptor blocker (IRBESARTAN) on left atrial remodelling and diastolic function.
