The government's prosecutor, Akram Sheikh, objected to the findings in the report, which was submitted by the four-member medical board headed by Maj General Syed Imran Majeed.
Musharraf's lawyer Anwar Mansoor requested the court to keep the report secret.
However, the prosecutor said Musharraf is a public figure and the report should be made public.
He said the Constitution includes a provision for a free press.
Sheikh demanded that another medical board, comprising cardiologists of Aga Khan Hospital, PIMS Hospital and Shifa International Hospital, should be formed to review the report.
He further said the report's findings seemed to imply that all heart patients should be sent abroad for treatment.
Ahmed Raza Kasuri, a key member of Musharraf's legal team, accused Sheikh of hosting an event for the media to turn them against him.
He claimed another medical report on Musharraf had also been made public and was available on the website of a news channel.
The three-judge special court subsequently adjourned proceedings till January 29.
Musharraf faces treason charges for abrogating the Constitution and imposing an emergency in November 2007.
