Causes of Heart Attack

Published on -

As per the WHO (World Health Organization), heart attack is one of the biggest causes of death worldwide. The major risk factors for heart attacks are high blood pressure, high cholesterol, and smoking, but there are additional unhealthy lifestyle and medical factors that can also raise your risk.

A heart attack, also known as a myocardial infarction, occurs when there is a blockage in the blood vessels that supply the heart muscle with oxygen and nutrients. This blockage is usually caused by a build-up of plaque in the arteries, which can rupture and form a blood clot that blocks the flow of blood.

Here are some major points for Causes of Heart Attack:

Coronary artery disease: This is the most common cause of heart attacks. It occurs when there is a formation of plaque in the coronary arteries, which can restrict blood flow to the heart.

Smoking: Smoking is a major risk factor for heart disease and can damage the lining of the blood vessels, leading to the build-up of plaque.

High blood pressure: High blood pressure can cause damage to the walls of the arteries, making it easier for plaque to form and block the flow of blood.

High cholesterol: High levels of LDL ("bad") cholesterol can contribute to the build-up of plaque in the arteries.

Diabetes: People with diabetes are at higher risk of developing heart disease, and high blood sugar levels can also contribute to the build-up of plaque.

Family history: People with a family history of heart disease are at higher risk of developing heart attacks.

Obesity: Being overweight or obese can increase the risk of developing heart disease, as it can contribute to other risk factors such as high blood pressure and high cholesterol.

Sedentary lifestyle: Lack of physical activity can contribute to the development of many risk factors for heart disease, including obesity, high blood pressure, and high cholesterol.

It's important to be aware of these risk factors and to take steps to manage them to reduce the risk of heart attack.
