PEACE Trial
Prevention of Events with Angiotensin
Converting Enzyme Inhibition (PEACE) Trial
Presented at
The American Heart Association
Scientific Sessions 2004
Presented by Dr. M. Pheffer
PEACE Trial
8,290 patients with stable coronary artery disease without heart failure
MI, CABG, or PCI at least 3 mo prior to enrollment, normal LV wall motion w/ EF>40%
82% male, mean age 64 years
90% received Aspirin, 60% beta-blockers, 70% lipid-lowering therapy
ACE Inhibitor Trandolapril
4mg/day
At 1 year, Trandolapril or open-label
ACE inhibitor taken by 81.9%
At 3 years, 74.5%
Placebo
At 1 year, 1.5% of patients on Ace
inhibitor
At 3 years, 8.3%

PEACE Trial: Summary
• Among patients with stable coronary artery disease and no heart failure, there was no difference in
the primary composite endpoint of cardiovascular death, nonfatal MI, and coronary revascularization
with the ACE inhibitor trandolapril or placebo.
• All individual components of the primary endpoint were equivalent between the two groups.
• A retrospective analysis of new onset diabetes and CHF as the primary cause of hospitalization or
death was found both to be lower in the trandolapril group.
• Trandolapril was associated with a significantly higher incidence of side effects leading to drug
discontinuation. Additionally, cough and syncope were each significantly higher in the trandolapril
cohort.
• The lack of benefit from ACE inhibitor therapy seen in this trial differs from the results of several
previous trials including the HOPE and EUROPA trials, which showed significantly lower incidences
of cardiovascular death, MI, stroke, and cardiac arrest in patients treated with ACE inhibitors than in
those treated with placebo.
•A possible reason for the lack of benefit with trandolapril could be that most patients were more
aggressively managed for risk factors with lipid-lowering medication and previous revascularization.
In accordance with this hypothesis, the PEACE trial had a lower event rate than the EUROPA and
HOPE trials.
