This new conceptual model has first led to the widespread       introduction of angiotensin converting inhibitors in clinical practice; then, the       evidence that sympathetic activation might play an important role in the       progression of heart failure, led the investigators to propose that beta-blocking       agents might be useful in the management of heart failure.
