title: Difficult cases in heart failure: Raison d'Être behind ACE inhibitors and AT1 receptor combinations in chronic heart failure: chemical nuances or clinical significance?
abstract: The following case description serves to illustrate the difficulties often faced in clinical practice in implementing what appear to be fairly simple and clear evidence-based guidelines regarding angiotensin-converting enzyme (ACE) inhibitors and no clear guidelines regarding angiotensin receptor blocker (ARB) use or, more importantly, ACE inhibitor and ARB combinations in chronic heart failure.
