Combined primary outcome of myocardial infarction, stroke
or cardiovascular death reduced by 25%, (ramipril 15.3%
versus 19.8% placebo).
Myocardial infarction reduced 22%, (ramipril 10.2% versus
12.9% placebo).
Stroke reduced 33%, (ramipril 4.2% versus 6.1% placebo).
Cardiovascular death reduced 37%, (ramipril 6.2% versus
placebo 9.7%).
Secondary outcomes
Total mortality reduced 24%
Revascularisation reduced 17%
Overt nephropathy reduced 24%
Overt nephropathy, laser, therapy or dialysis reduced 16%.
Other outcomes
Any heart failure reduced 20%.
Transient ischaemic attacks reduced 26%.
Worsening angina reduced 13%, (p=0.057).
The benefit of ramipril was noted irrespective of whether
subjects had a history of previous cardiovascular events,
hypertension or microalbuminuria, or whether the patients
had type 1 or 2 diabetes. At the end of the study there is no
significant difference in HbA1C% values.
Blood pressure difference was 2.47/1.00 in favour of ramipril.
After adjustment and changes in blood pressure, ramipril had
the same effect on primary outcomes as before adjustment.
Vitamin E had no significant effect.
Treatment of 1,000 patients with ramipril for four years will
prevent about 150 events in approximately 70 patients.
