DENVER -- The family of Colorado Rockies president Keli McGregor said he didn't die of a heart attack or other preventable cardiac condition but from a rare virus that attacked his healthy heart.
In a statement released through the team, his family said they wanted to "share this information with all of those who, like us, have searched for answers."
The family said McGregor, who was 48, likely contracted the virus in the last week of his life, causing lymphocytic myocarditis that led to his death on April 20 while on a business trip in Salt Lake City.
The family said the organism infiltrated his heart and disrupted the electrical pathways that signal the heart to beat properly. McGregor was an advocate for early detection and prevention of cardiovascular disease and had frequent checkups, the family said.
