Sports fans may be betting on more than their team while watching the big game. They could be putting their hearts on the line, too, a study of German soccer fans shows. Researchers found that the soccer fans more than doubled their risk of having a heart attack, experiencing serious chest pains, or developing an irregular heartbeat known as an arrhythmia while watching their national team play during the 2006 FIFA World Cup, which was played in Germany that year. The Italian national team won the tournament. Germany finished third.
