Heart attacks are often considered a disease that only affects the elderly. However, heart attacks in young people are becoming increasingly common. Many people aged 30-40 are even experiencing this condition.
Lifestyle changes, unhealthy diets, and prolonged stress are some of the factors that contribute to the increased risk of coronary heart disease in those of productive age. Therefore, it is important to understand the causes, symptoms, and ways to prevent heart attacks early.

What Is a Heart Attack?

A heart attack occurs when blood flow to the heart muscle is obstructed or stopped. This condition is usually caused by a blockage in the coronary arteries, the blood vessels that supply oxygen and nutrients to the heart.
If blood flow is interrupted for too long, the heart muscle can suffer permanent damage. Therefore, a heart attack is a medical emergency that requires immediate treatment.
