Sen. Bernie Sanders on Sunday balked at releasing medical records in the wake of a heart attack that briefly took him off the campaign trail last fall — insisting that he is “in good health.”

Speaking on NBC’s “Meet the Press,” the Democratic presidential hopeful said his campaign has “cardiologists who are confirming that I am in good health.”

“We have released as much documentation, I think, as any other candidate,” said Sanders, 78.

“But no other candidate has had a heart attack,” host Chuck Todd shot back.

“Yeah, no other candidate is doing four or five events a day running all over the country,” Sanders replied.

Todd had noted that in a Sept. 14 interview — prior to the heart attack in October — Sanders promised to release his medical records “before the first votes are cast.”

“The American people have a right to know whether the person they’re going to be voting for for president is healthy,” Sanders said at the time. “And we will certainly release our medical records before the primary.”

But he was singing a different tune Sunday, two days before the New Hampshire primary.

“I mean, you can start releasing medical records and it never ends,” he told the host. “We’ve released a substantive part — all of our background. We have doctors who have, cardiologists confirming that I am in good health. I am in good health.”

Sanders said doctors recommended he do more walking and get more sleep.

“My guess is winning will help you sleep a little bit better?” Todd asked.

“Winning will make me sleep a lot better and I think we’re going to do just that,” Sanders said.
