Watching football causes heart attacks

The Junkfood science blog writes:

The Super Bowl, and all spectator competitive sports, may be a thing of the past, in accordance with current public health policies. A new study has found such sporting events are associated with a 326% increase in cardiac emergencies among men and nearly a doubled risk among women. These are actual myocardial infarctions and cardiac arrhythmias, not surrogate endpoints for heart problems. For those with heart disease, the risks are twice those of people without a history of heart problems.

He argues that banning the Super Bowl makes about as much sense as banning transfats.
