Heart attacks occur when the interior of one or more coronary arteries narrows due to a gradual build-up of fat deposits called the atheroma. When a piece of fat breaks off, a blood clot forms to repair this damage to the arterial wall. When the blood clot forms, it can block the coronary artery, causing part of the heart muscle to lose blood and oxygen. In this case, a person suffers a heart attack.

There are people who are more prone to a heart attack.

The main risks include:

Have high blood pressure

Blood pressure refers to the force that pumps blood through the circulatory system.

When blood circulation is limited, the heart muscle is lacking in oxygen, resulting in a heart attack. The higher the blood pressure, the higher the likelihood of heart attack.

To be overweight

If a person is overweight, there is a greater risk of medical problems that cause heart disease.

Obesity is associated with an increased risk of cardiovascular disease. If you carry most of your weight around your stomach, there is a high risk of a heart attack.


The carbon monoxide in the tobacco smoke reduces the oxygen content in the blood. This leads to increased blood clotting and thus to an increased risk of heart attack or stroke.

Have high cholesterol

Too much cholesterol in the body means that you are a high risk factor for heart disease. If the blood contains too much cholesterol, it accumulates in the walls of the arteries.

The arteries are narrowed and blood circulation is reduced, resulting in a heart attack.

Have diabetes

People with diabetes are more likely to develop heart disease and have a higher risk of heart attack or stroke.

The blood sugar level of a diabetic patient damages blood vessels and nerves over time and this damage eventually leads to heart attacks.

family history

Genetics that is predisposed to heart attack carries a higher risk of even having a heart attack.

Having a high genetic risk for heart disease doubles the risk of heart attack.

Thankfully, many of these risks can be reduced if a person leads a healthy lifestyle. The foods you eat can reduce the risk of heart disease and stroke.

Sport helps lower high blood pressure and raise HDL (good cholesterol) levels, which is associated with a reduction in heart attack risk.
