The fast food, fast life diet of the West is heavy on meat, fried foods and salty snacks and low on fruits and vegetables.
But how much can you blame on diet when it comes to heart attacks? And does that differ from country to country?
A group of researchers decided to look at the food habits of thousands of people in 52 countries.
They asked their subjects what they usually ate, then gave each person a dietary score based on a defined set of good and bad foods.
They found that if you compared heart attack patients against those who had no heart disease, the pattern was consistent.
About 30 percent of someone's risk of heart disease is linked to choosing a typical Western diet.
Doctors said a dietary questionnaire is an easy and inexpensive way to measure how likely someone is to have a heart attack.
