Fitzgerald, an alcoholic since college, became notorious during the 1920s for his extraordinarily heavy drinking, which would undermine his health by the late 1930s. His alcoholism resulted in cardiomyopathy, coronary artery disease, angina, dyspnea, and syncopal spells. According to Zelda's biographer, Nancy Milford, Fitzgerald claimed that he had contracted tuberculosis, but Milford dismisses it as a pretext to cover his drinking problems; however, Fitzgerald scholar Matthew J. Bruccoli contends that Fitzgerald did in fact have recurring tuberculosis, and according to Milford, Fitzgerald biographer Arthur Mizener said that Fitzgerald suffered a mild attack of tuberculosis in 1919, and in 1929 he had "what proved to be a tubercular hemorrhage". In the 1930s, Fitzgerald had told Hemingway of his fear of dying from "congestion of the lungs." Others have suggested that the writer's hemorrhage was caused by bleeding from esophageal varices.
