Executive Summary
Bypass surgery patients were less likely to need revascularisation than those treated by PTCA or medication in the Brazilian Medicine Angioplasty or Surgery Study (MASS). None of the bypass patients needed revascularisation during a three-year follow-up period. All three strategies eventually eradicating limiting-angina but bypass and angioplasty gave greater initial relief and better treadmill test scores. There was no difference in mortality or infarction rates, says Dr Whady Hueb, writing in the Journal of the American College of Cardiology (December).
