Myocardial infarction Subendocardial

Myocardial infarction Subendocardial.

Myocardial infarction is a serious heart disease that can lead to death. One of the most common types of myocardial infarction is subendocardial infarction. In this article we will look at what myocardial infarction is, how it manifests itself and how to treat it.

Definition Myocardial infarction is the necrosis of cardiac muscle tissue, necrosis of part of the myocardium, limited to one or more coronary arteries. In the vast majority of patients, infarction occurs in the subendocardial zone, since there are rarely collaterals between the coronary and

Subendocardial myocardial infarction: causes, symptoms and treatment

Myocardial infarction is a serious heart disease that occurs due to insufficient blood supply to the heart muscle. One form of myocardial infarction is subendocardial myocardial infarction. In this article we will look at the main causes, symptoms and treatment of this condition.

Subendocardial myocardial infarction, also known as subendocardial myocardial infarction, is characterized by damage to the inner layer of the heart muscle. This layer is closer to the heart cavity and is most vulnerable to lack of blood supply. Subendocardial myocardial infarction can occur due to obstruction of the coronary arteries responsible for supplying blood to the heart.

One of the main causes of subendocardial myocardial infarction is atherosclerosis, in which plaques from fatty deposits form on the walls of the coronary arteries. These plaques can lead to the formation of blood clots, which block blood flow to the heart muscle and cause a heart attack.

Symptoms of subendocardial myocardial infarction may include:

1. Chest pain. The patient may experience severe pressing or squeezing pain in the chest area, which may radiate to the left arm, neck, or jaw. The pain may be prolonged and not relieved by rest or nitroglycerin.

2. Dyspnea. The patient may experience difficulty breathing, even at rest or with minor physical exertion.

3. Weakness and fatigue. The patient may feel general weakness and fatigue for no apparent reason.

4. Dizziness and loss of consciousness. In some cases, subendocardial myocardial infarction can cause dizziness and even loss of consciousness.

Treatment of subendocardial myocardial infarction requires immediate medical attention. The primary goal is to restore blood supply to the heart and prevent further damage to the heart muscle.

Standard treatment may include the following measures:

1. Thrombolytic therapy. Medical administration of drugs aimed at destroying the blood clot and restoring blood flow in the blocked artery.

2. Anticoagulant therapy. The use of drugs that prevent the formation of new blood clots and improve blood flow.

3. Antiplatelet therapy. Using medications such as aspirin to prevent platelets from sticking together and forming new blood clots.

4. Dilation of the coronary arteries. In cases where a blood clot has formed in a narrow or obstructed artery, an angioplasty or stenting procedure may be required to restore normal blood flow.

5. Rehabilitation and lifestyle changes. After a subendocardial myocardial infarction, it is important to carry out rehabilitation measures, including physical activity, blood pressure and cholesterol control, a healthy diet and smoking cessation.

It is important to note that subendocardial myocardial infarction is a serious condition that requires immediate medical attention. If you experience the symptoms described above, seek immediate medical attention.
