Ten year follow up of patients referred for CABG from a single DGH

Sir ,-Bathgate and Irving have wisely pointed out that the 10 year overall clinical results of coronary bypass can be disappointing. 1 However, patients with severe class IV angina experienced pronounced symptom relief, allowing return to work in 91 of 100 consecutive bypassed cases, and an apparent improvement in survival with 88% alive a decade later. 2 It seems that bypass is more beneficial in this group of more severely symptomatic patients, especially in those with advanced triple vessel or left main fixed disease when left ventricular function is impaired.
