Lewis suffered numerous heart problems throughout his life; he revealed in the 2011 documentary "Method to the Madness of Jerry Lewis" that he suffered his first heart attack at age 34 while filming "Cinderfella" in 1960. In December 1982, he had another heart attack. Several months later, in February 1983, Lewis underwent emergency open-heart double-bypass surgery. En route to San Diego from New York City on a cross-country commercial airline flight on June 11, 2006, Lewis suffered his third heart attack. It was discovered that he had pneumonia, as well as a severely damaged heart. He underwent a cardiac catheterization days after the heart attack, and two stents were inserted into one of his coronary arteries, which was 90 percent blocked. The surgery resulted in increased blood flow to his heart and allowed him to continue his rebound from earlier lung problems. Having the cardiac catheterization meant canceling several major events from his schedule, but Lewis fully recuperated in a matter of weeks.
