TORONTO -- Nurse Donna Riley hurried through the drab halls of St. Michael's Hospital to deliver the bad news. Eduard Krause, a 71-year-old retired mechanic, had been waiting more than six weeks for heart-bypass surgery. After fasting for 18 hours, he was lying on a gurney, ready to be rolled into the operating room. Now, he would have to wait a bit longer: An emergency patient had been rushed into surgery, bumping him from the day's schedule.
