What is a heart attack?

A heart attack is a very dangerous situation that occurs when a coronary artery is occluded. The coronary arteries or arteries that carry blood to the heart muscle, and the heart is the one that pumps blood to the rest of the body.

When we have a heart attack it usually occurs because a thrombus has formed inside a coronary artery and occludes and prevents an area of ​​the myocardium, the muscle of the heart, from receiving blood, so that at that moment the heart, that part of the heart, It begins to die.

This can have tragic consequences such as death by an arrhythmia or, in the case of this does not occur, or is controlled, there is a scar on the heart, so that what was previously muscle that was pumping blood is now they become a scar that does not move and that therefore pumps blood, which causes us to enter a situation we call heart failure.


Why is it produced?

Since we are born in our arteries, specifically in our coronary arteries, we start depositing cholesterol and other substances forming what is called coronary arteriosclerosis plaques. When one of these plaques becomes unstable, and this is when a plaque breaks, the contents inside that plaque come in contact with the blood and in that way a clot is produced that is going to be what occludes the blood vessel.

What is the best way to avoid having a clot, that we have a thrombus and therefore avoid a heart attack? Try not to have arteriosclerosis plaques.


Can it be prevented?

Preventing a hundred percent heart attack is practically impossible. Infarction is one of the pathologies, one of the most frequent diseases in our society, in our country. However, we can do things that help us try to avoid or try to prevent us from having a heart attack.

The adequate control of cholesterol levels, of course stop smoking, control our diabetes, exercise, avoid overweight, and control our blood pressure are measures that help us slow down or slow down at least the progression of these arteriosclerosis plaques, try that these plates do not become unstable, and therefore we try to avoid that we develop, that we have a heart attack.


How does it affect the patient's life?

The consequences of a heart attack are multiple. There are people who do not surpass the first minutes since a heart attack starts, in such a way that they usually do a deadly arrhythmia that we call ventricular fibrillation, that if it is not treated at that moment the consequence is the death of the patient.

However, other times it is not produced or managed in time, but if, as we said before, a scar remains to the heart, that scar on the one hand can be the origin of new arrhythmias, and on the other hand reduces the function of the heart as a pump. That scar that used to be muscle and is now an inert tissue that does not move what it produces is that the capacity to pump the heart is considerably reduced, so we have what we call cardiac insufficiency.

This cardiac insufficiency greatly impairs the quality of life of any person and is a marker that tells us that our life expectancy is shortened.
