Heart bypass surgery
After the operation, the patient will spend 5 - 10 days in the hospital, the first 1 - 3 days in an intensive-care unit (ICU). Chest tubes will be in place for the first 2 to 3 days to drain any residual blood and fluid from around the heart. Heart functions will be monitored. The full benefits from the operation may not be clear until 3 - 6 months after surgery. Sexual activity may be resumed 3 - 4 weeks after surgery. All activities that do not cause fatigue are permitted, but the patient must not strain the healing chest bone (sternum).
