KARACHI: Prime Minister Nawaz Sharif was discharged from hospital on Monday after a week-long stay following his open heart surgery, state media reported.

The wife of prime minister Kulsom Nawaz and his two sons Hassan Nawaz and Hussain Nawaz accompanied the premier on his way home.

It was the 66-year-old's second major cardiac medical procedure in five years.

The London hospital where the procedure was carried out has not been officially named.

Earlier in the day, premier's daughter Maryam Nawaz had said that Nawaz Sharif will hopefully be discharged from hospital in the afternoon as doctors are satisfied with his progress and latest test reports.

Maryam tweeted on Monday saying “doctors satisfied with PM's progress and latest reports. All being well, Insha'Allah PM will be discharged this afternoon”.

On Sunday, nearly a week after the premier underwent surgery, Maryam had announced that Nawaz Sharif's recovery was on track.

"PM's recovery on course. Was made to walk several times in the corridor during the day, and up and down a flight of stairs twice," Maryam tweeted.

Since Nawaz was hospitalised, Maryam has taken charge of media management in the Sharif camp, feeding the press updates on her father's medical condition.

From announcing the prime minister’s decision to undergo the surgery, to tweeting his first picture after the procedure, Maryam’s Twitter feed has provided minute details about how much time the patient would spend inside the intensive care unit (ICU), as well as his tentative plans to come back home.

Prime Minister Nawaz Sharif underwent a successful open-heart surgery at a London hospital and was moved to an intensive care unit in a stable condition on Tuesday. He is expected to return to Pakistan before the end of Ramazan, Maryam said earlier.

"Three of his arteries were blocked. It will take five or six days for the prime minister to get discharged from the hospital and we expect that he will return home in three to four weeks," she said on Wednesday.

Following his surgery, the premier will be overseeing the affairs of government from London.
