A doctor at the Santiago military hospital says Tuesday former Chilean dictator Augusto Pinochet is out of critical condition following a heart attack.
The 91-year-old former leader is expected to remain in the hospital for a week. He underwent an angioplasty Sunday to reopen his arteries.
General Pinochet has been accused of numerous human rights violations during his 1973 to 1990 rule.
More than 3,000 people disappeared or were killed for political reasons during that time.
On Monday, an appeals court released him from the house arrest imposed last week in connection with the killing of two bodyguards of the president he overthrew in 1973.
On General Pinochet's 91st birthday last month, he said he took what he called "political responsibility" for everything that happened during his rule.
The general has been stripped of the legal immunity granted to former presidents.
But he has avoided prosecution, as Chilean courts have ruled he is physically and mentally unfit to stand trial.
