Spokesman Freddy Ford says the 43rd president is expected to be discharged Wednesday. He would not give a specific time.
Doctors at Texas Health Presbyterian Hospital on Tuesday inserted a stent to help prop open an artery. The blockage was discovered Monday during Bush's annual physical at a clinic in Dallas, where he lives.
Ford says the 67-year-old former president is expected to resume his normal schedule by Thursday.
Bush has a reputation as a fitness buff and is known to enjoy jogging, riding bicycles and doing other exercise to keep in shape.
