The 43rd president had a heart stent implanted at Texas Health Presbyterian Hospital after the blockage was found during an annual checkup. The obstruction was found on Monday at the Cooper Clinic in Dallas.

A spokesman said the former president is in "high spirits."

"President Bush is in high spirits, eager to return home tomorrow and resume his normal schedule on Thursday," a Bush spokesman said in a statement.

"He is grateful to the skilled medical professionals who have cared for him. He thanks his family, friends and fellow citizens for their prayers and well wishes. And he encourages us all to get our regular check-ups."

Bush's father, former President George H. W. Bush, was hospitalized at the end of 2012 while he fought complications caused by persistent bronchitis. But the younger Bush is said to be healthy, and has long been an avid biker.

The 43rd president has kept a low profile since leaving the office, but has reemerged in public life since the dedication of his presidential library in April.

He recently delivered a speech on the need for immigration reform at a forum at the George W. Bush Presidential Library and Museum.
