Why do heart attacks happen?

There are various risk factors that may have contributed to your heart attack, spanning everything from lifestyle to medical conditions and demographics.


Some risk factors can’t be changed, such as age, gender, and genetics. Others can be managed such as:

  • Lifestyle (diet, exercise, smoking, alcohol)
  • Medical conditions (high cholesterol, diabetes, high blood pressure, obesity)


If you’ve already a heart attack, you are at a higher risk of having another one. This is why it’s so important to understand how making some changes can help reduce this risk.
