Being named as a Communist caused John Garfield to have a heart attack.

 

Well, no, not really. Despite long-term heart problems,  Garfield was a smoker and drink. When he died he was in the midst of a divorce. On the morning of May 20, Garfield, against his doctor's strict orders, played several strenuous sets of tennis with a friend, mentioning the fact that he had not been to bed the night before. He met actress Iris Whitney for dinner and afterward became suddenly ill complaining that he felt chilled. She took him to her apartment, where he refused to let her call a doctor and instead went to bed. The next morning, she found him dead.
