There are multiple suggestions for prevention of heart attack – screening, genetic testing, medications, lifestyle modifications, treatment of underlying health conditions. However, the first action on your part should be awareness of myths. You need to dispel these wrong notions first and follow expert advice. Let’s look at some of the common myths.

1. I am fit, I need not worry – Your physical fitness is good, and important for the health of your heart. However, it does not protect you from the risk of heart attack. Because there are other factors like your diet, genetics, and lifestyle.
2. I am young, only old people are at risk – Young people are increasingly prone to heart attacks as can be seen from multiple news reports daily. Though it is true that risk increases with age, young people are also at risk due to obesity, smoking, diabetes, or family history.
3. There is family history of heart disease, and I am doomed – This is a wrong assumption. Though family history of heart disease will put you at increased risk, you can greatly reduce the risk. You will need to follow a balanced diet, exercise regularly, quit smoking, and adopt a proper lifestyle. 
4. I got myself tested, I am diagnosed with heart disease, there is nothing that can be done – If you have been diagnosed with heart disease, it is not the end. There are multiple options available to improve your heart health and reduce your risk of heart attacks. This includes following lifestyle recommendations for heart attack prevention, quitting smoking, adopting a heart-healthy diet, with a good exercise regimen. Medications and procedures also considerably mitigate risks. 
5. My gender is feminine, since the risk is only for men, there is no reason for alarm – Both men and women are equally at risk of heart attack. The major difference is the different symptoms experienced by men women. As a result of these changes in symptoms, people end up remaining undiagnosed. 
6. I take vitamins and supplements, and therefore I am not at risk – A balanced diet is good for heart health, and this means more fruits, vegetables, whole grains, and lean proteins. Presently, there is no scientific evidence to claim that supplements offer protection from heart attack. 
7. I take red wine, and this is good for my heart – Some benefits may accrue from moderate consumption; however, it is never a recommendation for everyone. This is because there is a possibility of other risks from such consumption, which may indirectly result in putting you at risk of heart attack.
8. I have low cholesterol levels, and therefore I am not at risk – High cholesterol is a contributing factor to high risk of heart attack. However, there are other factors like blood pressure, smoking, genetics and diabetes. By having low cholesterol levels, you are not free from these risks, and it is necessary to assess all your risk factors, and follow lifestyle recommendations for heart attack prevention. 
9. I avoid all fats and this is the best decision – There are healthy fats, that can actually protect your heart. This includes fat in avocados, nuts, seeds, and fish. Instead of avoiding all fats, the best option is to reduce intake of saturated fats and stay away from trans fats, while consuming healthy fats. 
10. I exercise intensely and therefore I will not get a heart attack – There are multiple examples of people experiencing a heart attack in gyms. There are numerous examples of fully fit, young people having a heart attack. It is true that moderate exercise performed consistently will contribute to heart health. However, this is not a guarantee from risk due to other factors.
