Severe consequences of myocardial infarction

To better understand why the consequences of myocardial infarction are so serious, let's figure out what constitutes this serious disease, which becomes younger and more and more lives year after year. What provokes the appearance of dangerous symptoms?

Myocardial infarction - consequences of atherosclerosis

Before there is a myocardial infarction, there is a violation of blood supply in the muscle layer of the heart as a result of blockage of blood vessels, which, in turn, leads to the necrosis of these tissues. This pathology requires urgent treatment, otherwise the consequences of it will lead not only to disability, but also to death.

The main cause of these disorders is atherosclerosis - a disease of the coronary arteries that feed the heart muscle. It manifests itself in the narrowing of the lumen of the blood vessels, and this, in turn, leads to a chronic lack of oxygen in that part of the heart muscle that they feed. At the moment of pulsation, the lost elasticity, the deformed arteries can crack, which triggers the formation of a thrombus. It closes the lumen completely, and the tissue, which has lost its nutrition, begins to die, giving rise to acute myocardial infarction.

Myocardial infarction: causes and consequences of the disease

According to bitter statistics, about half of people who have had a heart attack die within the first hours. All this happens, because the disease affects the whole body in the most serious way. Those who survived on the site of necrosis of the heart tissue formed a scar, because of which the heart muscle will never be able to function as productive as before.

The transferred infarct creates foci of intracardiac conduction disturbances that cause failures in the rhythm of the heart. The appearance of paroxysmal ventricular tachycardia and atrial fibrillation may further lead to acute heart failure.

There are other, no less severe pathologies caused by a heart attack.

Consequences of myocardial infarction - pulmonary edema and cardiac asthma

Against the background of a heart attack after a breach of pressure in the left ventricle of the heart, the so-called left ventricular failure is formed, which leads to an increase in pressure in the vessels of the lungs and the release of blood into the lung tissue. All this provokes pulmonary edema, which causes an attack of asthma in the patient.

The consequences of myocardial infarction - heart rupture and pulmonary artery occlusion

Rupture of the heart is the most rare consequence of this disease, and the mortality rate is 100%. It occurs in the first days of a heart attack, manifested by severe pain, not susceptible to analgesics, and a picture of cardiogenic shock. Tamponade of the heart causes it to stop quickly, which leads to death.

No less serious consequence is a blockage of the pulmonary artery, which causes a thrombus, which gets into it from the right ventricle of the heart. Corking also leads to instant death.

Consequences of myocardial infarction - disruption of the internal organs

Because of the violation of blood circulation against the background of a heart attack, paresis of the gastrointestinal tract, ulcers and erosion of its mucous membrane, as well as atony of the bladder may occur. All these diseases are called abdominal syndrome and develop in the acute period of a heart attack.

No less frequent are the mental disorders that are more common in older people. They are manifested by depression, followed by euphoria and are associated with hypoxia and thrombosis of the cerebral vessels that have arisen against the background of a heart attack.
