A pooled analysis of morbidity-mortality trials Inclusion criteria: Morbidity-mortality trials including ACE or ARBs inhibitors in treatment arms conducted from 2000 to June 2010 Trials including mainly hypertensive patients ( >66% of studied population, according to the trial-specific definition) All-cause mortality: a pre-specified or reported in the principal study publication (an integrative end point taking into account both the benefits and severe adverse events of treatment devoided of bias or uncertainty) Exclusion criteria: Heart failure/acute coronary syndromes/acute stroke/ hemodialysis/atrial fibrillation or post-cardiac surgery trials Objective:To evaluate the impact of RAAS inhibitors on further mortality reduction in their main indication, hypertension, in patients representative of those treated in the XXIst century.

Conclusion • Among RAAS inhibitors, only ACE inhibitors have demonstrated a further significant 6% mortality reduction in hypertensive patients (P=0.007) • No significant reduction in all-cause mortality could be demonstrated with ARBs (HR, 0.99 (0.95-1.04), P=0.75) • Perindopril significantly reduced all-cause mortality by 13% among contemporary patients with arterial hypertension (P<0.001) • Treatment with ACE inhibitors would additionally save 12 lives for every 1 000 patients treated for 4 years M.
