Former Vice President Dick Cheney remains hospitalized after heart surgery last month but is out of the intensive care unit and could return home this week, his daughter said Sunday.

Liz Cheney said on “Fox News Sunday” that her father planned to resume fly-fishing and hunting after the operation more than three weeks ago in which doctors implanted a small pump in his heart.

Cheney has a history of heart problems, including five heart attacks, and the procedure he underwent is used in severe cases that require a mechanical pump to keep the circulation going, said Dr. Tim Gardner, former president of the American Heart Association.

Gardner was not involved in Cheney’s treatment.

Cheney suffered his first heart attack in 1978 at age 37. He also suffered heart attacks in 1984 and 1988, and underwent a quadruple bypass surgery to unblock his arteries.

Shortly after Cheney was elected vice president in November 2000, he had a fourth heart attack and received a stent to open an artery.

In February, Cheney suffered his fifth heart attack.
