About 6 per cent of patients who have coronary bypass surgery could suffer a stroke directly afterwards. Of these, 5 per cent die, and nearly half suffer deterioration in their intellectual functions.
These strokes are "common and serious", conclude the researchers who made the discovery and it could mean that more than 48,000 people a year around the world suffer a stroke directly after major heart surgery.
The findings were based on the records of 2108 patients who had bypass surgery at one of 24 US hospitals. Of these, 129 patients or 6.1 per cent of the total suffered a stroke, the Multicenter Study of Perioperative Ischemia Research Group discovered.
