Abstract
We conducted a prospective, randomised, open-label, blinded end point (PROBE) study examining the relative efficacy of irbesartan 300 mg/day versus maximising dose of ACE inhibitor, additional to background conventional heart failure therapy. Patients with CHF, NYHA Class II-III and a left ventricular ejection fraction <40% were randomised to one of two treatment arms. All patients were receiving ≤ half target dose of ACE inhibitor as background therapy. 44 patients received an increase in their background ACE inhibitor while 45 patients were given irbesartan (target dose 300 mg/day) in addition to their background ACE inhibitor. The primary end-point was change in brain natriuretic peptide (BNP) from baseline to 6 months. Change in hs-CRP level, 6 min walk distance, and Minnesota living with heart failure quality of life questionnaire (MLWHF) from baseline to 6 months were also evaluated. Patients were well matched at baseline for all end-point parameters as well as for age, gender and baseline systolic ventricular function. There was general improvement in clinical status for all patients but no significant difference between increased ACE inhibitor vs added ARB for change in BNP, hs-CRP, NYHA, 6 min walk or MLWHF (all P>0.05). This PROBE study has demonstrated similar clinical responses with increased dose of ACE inhibitor compared to addition of ARB in patients with systolic CHF. These findings suggest that either approach to increasing renin-angiotensin blockade in patients taking low doses of background ACE inhibitor results in similar clinical outcomes.

Abstract
Chronic heart failure (CHF) is a complex syndrome involving activation of multiple cellular, metabolic, and neurohumoral pathways following the initial myocardial insult. Recently, there have been considerable advances in the pharmacologic management of CHF. The current approach to treatment recognizes the need to target neurohormonal activation, and the use of angiotensin-converting enzyme (ACE) inhibitors and beta blockers should now be regarded as part of standard therapy in many patients with CHF. However, because of the complexity of the disease, blockade of additional pathways is likely to be required to maximize the therapeutic benefit of intervention. To this end, there are several agents under active late-phase clinical evaluation. The most advanced of these new strategies (beyond renin-angiotensin-aldosterone blockade) is inhibition of the endothelin system. There is a substantial body of evidence that this system is intimately involved in CHF disease progression. Early-phase clinical data are very encouraging and support the potential utility of long-term endothelin inhibition. Other novel approaches involve the use of cytokine antagonists (e.g., agents that block tumor necrosis factor-alpha activity) and the augmentation of natriuretic peptides. If all these potential agents prove to be of benefit in CHF, the question of which agent or combination of agents to use in which patients will arise. There is therefore a need to develop scientific approaches in order to be able to identify more accurately patients who will obtain benefit from specific classes or combinations of drugs.
