A heavy meal can dramatically increase a person's risk of having a heart attack soon after eating, according to a new study. The risk increased 10-fold in the first hour following the oversized meal, reduced to 4-fold by the second, and was almost gone 3 hours later—all compared with the risk during the same period the day before, when some people in the study had eaten a normal meal.

Heavy meals could thus be an important trigger of heart attacks among people prone to heart disease—including those with high blood pressure, obesity, and diabetes—says lead researcher Francisco Lopez-Jimenez of Brigham and Women's Hospital in Boston. The boost in risk may not matter as much to a young, healthy person, he says.
