However, on the advice of doctors, the English midfielder has taken the decision to retire from the game.
Muamba told the club's official website: "Since suffering my heart attack and being discharged from hospital, I have remained utterly positive in the belief I could one day resume my playing career and play for Bolton Wanderers once again.
"As part of my ongoing recovery, last week I travelled to Belgium to seek further medical advice from a leading cardiologist. But the news I received was obviously not what I had hoped it would be and it means I am now announcing my retirement from professional football.
"Football has been my life since I was a teenage boy and it has given me so many opportunities. Above all else, I love the game and count myself very lucky to have been able to play at the highest level.
"While the news is devastating, I have much to be thankful for. I thank God that I am alive and I pay tribute once again to the members of the medical team who never gave up on me.
"I would also like to thank everyone who has supported me throughout my career, and the Bolton fans who have been incredible. I am blessed to have the support of my family and friends at this time."
Muamba also represented Arsenal and Birmingham City.
