Former Condé Nast Publications Inc. chief executive officer Steve Florio has been hospitalized and is seriously ill following a recent heart attack. Florio, 58, has a history of heart problems: he had surgery to replace a faulty valve in 1999 and a second surgery a few years later to correct a manufacturer’s defect on the replacement valve.

Florio retired from Condé Nast in February 2004 and remained under contract with the company as vice chairman until January 2007. Since his retirement, he has served as adjunct professor at New York University, in the entertainment, media and technology program, and is an investor in Tutto Il Giorno, a restaurant in Sag Harbor, N.Y.

A spokeswoman for Condé Nast, which also owns WWD, said, “We wish and hope for a good recovery.”
