Although the article published in The News-Gazette is a syndicated column via the AP White House reporter Jill Colvin, the headlines are created locally by each individual newspaper/outlet wishing to publish the story. We have reason to believe this is straight from the editorial desk of News-Gazette, though we're waiting to confirm whether or not this is the case.
Regardless, it reads in an interesting way.
Following the recent physical that Donald J. Trump underwent, the comma is placed... well, just look and read it. It reads as though they're saying the Donald has "no heart", which seems very, very accurate given his track record.
By the way this reads, it sounds like the doctor is saying that Trump has no heart, though he has cognitive issues. Not necessarily that he has no heart issues and no cognitive issues.
