[ACE inhibitor or AT1 antagonist. Is there a differential therapy?].
ACE-inhibitors and AT, receptor antagonists play an important role in the treatment of cardiovascular and renal diseases. The criteria of evidence-based medicine indicate that ACE-inhibitors (in appropriate combinations with other cardiovascular agents) continue to represent the treatment of first choice in chronic heart failure, post-myocardial infarction with compromised ventricular function, high cardiovascular risk, and diabetic (type 1) nephropathy. It is here that the AT1 antagonists should be used--in particular when ACE-inhibitors are not tolerated. The AT1 antagonists, Irbesartan and Losartan, are applied, at appropriately high doses, primarily in hypertensives with diabetic (type 2) nephropathy. With the current exception of chronic heart failure, no confirmed data are yet available on the value of combination treatment. The LIFE study has shown that an AT1 antagonist is superior to an established beta blocker in hypertensives with an increased risk (left-ventricular hypertrophy), in particular when diabetes mellitus is impending or already present.
