Myocardial infarction (heart attack) is caused by a blockage or lack of blood flow to the heart due to plaques formed by blood clots.

Common symptoms of myocardial inarction include a sudden tightness in your chest. This tightness in your chest causes severe pain that can also induce nausea, breathing difficulties, vomiting, and hypothermy.

High blood pressure, hyperlipidemia, diabetes, and smoking are all major risks of myocardial infarction. These factors causes plaques to form and narrow the arteries, which can lead to atherosclerosis. Plaques within the arteries block or limit blood flow into the heart, causing myocardial infarction.

LTA (Lymphotoxin-a) gene can also incur myocardial infarction.

Mutation in this gene increases inflammation in the blood vessels, leading to higher risk of having a heart attack.

Prevention 1. Increasing HDL level

HDL (High Density Lipoprotein) reduces the risk of myocardial infarction by removing LDL (Low Density Lipoprotein) from the bloodstream and strengthening blood vessel walls. You can increase the HDL level by eating foods rich with unsaturated fat.

Prevention 2. Low sodium, low fat diet

Salty foods increase blood pressure and promote the development of atherosclerosis. Taking on a low sodium, low fat diet and eating vegetables and fruits are recommended to reduce the risk of myocardial infarction.

Prevention 3. Working out

Exercising 30~40 minutes everyday can prevent hyperlipidemia and obesity, reducing the risk of developing heart diseases. Walking, jogging, and cycling are aerobic exercises that are beneficial for your health.

Myocardial infarction is the leading cause of sudden death in adults. It is recommended that you implement your lifestyle and regular health checkups to prevent myocardial infarction.


Genetic analysis test on myocardial infarction is done in Genoplan Japan.
