Former Boston Red Sox pitcher Curt Schilling said he suffered a heart attack in 2011 when he was trying to start his video game company, 38 Studios.
Schilling told The Boston Globe he started suffering chest pains while watching his wife run in the New York City Marathon.
He said he went to a Boston hospital when he returned and doctors put in a stent.
Seven months later, 38 Studios went bankrupt.
Schilling said he was devastated by the company's failure and that he lost nearly $50 million of his own money.
