The human body is a very complex structure. Every vein and organ, It continues to work non-stop in coordination with each other. The heart is one of them.

Well, even if we don’t feel it at all What happens during a heart attack?

Although a heart attack may seem like a second or minute emergency, the groundwork was laid years or decades ago.

The heart is a muscular organ. The average adult heart is beats 100,000 times a day and pumps about 5.6 liters of nutrient-rich and oxygen-rich blood into the body every minute. Blood first travels from the heart to the lungs, where it is oxygenated.

It then returns to the heart to be pumped into the arteries to deliver nutrients and oxygen to the brain, digestive system, and other tissues of the body. In the process leading to a heart attack Primary coronary arteries, which supply oxygen and nutrients to the heart muscle, narrow over the years.

This condition is largely due to atherosclerosis, the buildup of fatty plaques on the artery walls. In addition, the hard outer surface of the plaques can sometimes crack and break down blood components called platelets. It can stick to cracks and cause the artery to narrow further.

If the arteries are already narrowed by years of build-up of fatty plaque, the clot can completely block blood flow to the heart.

However, pieces of plaque can break off and travel through the arteries, causing the blockage to quickly worsen. Here are such blockages, It causes a heart attack. The muscle cells in the heart are damaged and begin to die within minutes.

Although less common, in the walls of the coronary arteries A sudden spasm or contraction can block blood flow and cause a heart attack. These spasms are most common in smokers and people with high cholesterol or high blood pressure.

In summary, the heart is a very complex organ. The occurrence of a heart attack is as mysterious and As we have repeated, this occurs as a result of long-term problems with the heart and blood vessels.
