Why does myocardium have ischemia, what is myocardial ischemia, and what are your opinions?

Decreased blood pressure, decreased blood supply to the aorta, and blocked coronary arteries can directly lead to a decrease in blood supply to the heart; Valvular heart disease, changes in blood viscosity, and lesions of the heart muscle itself can also reduce the blood supply to the heart. There is also a condition in which the blood supply to the heart is not reduced, but the oxygen requirement of the heart increases, which is a type of relative myocardial ischemia. The blood vessels that supply blood to the heart are called coronary arteries, and their openings are in the ascending aorta.

Clinical results show that the main and most common cause of myocardial ischemia is coronary artery stenosis. And the main cause of coronary artery stenosis is atherosclerosis. Cause.

Coronary atherosclerosis.

The heart disease caused by it is often referred to as coronary heart disease.

Therefore, coronary heart disease is the "main culprit" of myocardial ischemia.

Myocardial ischemia can have many adverse effects on the heart and throughout the body. Oxygen is essential for the activity of heart muscle cells, and oxygen is delivered to cells through the blood. The heart does not have an "oxygen storehouse" and is completely dependent on the blood supply to the myocardium, so once it is ischemia, it will immediately cause hypoxia.

The direct consequence of hypoxia is that the aerobic metabolism of myocardial cells is weakened, and the production capacity is reduced, so that the necessary energy ** for heart activity is insufficient, causing angina, arrhythmia, and decreased cardiac function. At the same time, metabolic wastes cannot be effectively removed in a timely manner, which is prone to adverse effects. Ischemia, hypoxia, and energy deficiency will eventually affect the systolic function of the heart.

Left ventricular failure usually occurs if the myocardium stops contracting in 20 25; If more than 40 percent of the heart muscle fails to contract, severe heart pump failure occurs. If this happens suddenly, a very dangerous cardiogenic shock can occur. Acute myocardial infarction is often associated with this condition.

Myocardial ischemia can also impair diastolic function. The combination of poor systolic and diastolic tends to lead to increased ventricular filling pressure, pulmonary congestion, complex substance metabolism disorders, and myocardial electrical activity abnormalities. Therefore, once myocardial ischemia occurs, it is necessary to find the right symptom to avoid potential serious consequences.

Myocardial ischemia is a type of coronary heart disease, and the first regimen is to choose nitrates (such as isosorbide mononitrate or its extended-release dosage form), which is used to dilate the coronary arteries of the heart and increase the blood supply to the myocardium; Statins (such as avastatin, simvastatin) should also be taken to reduce cholesterol in the plasma on the one hand, stabilize the arterial plaque on the other, and prevent the plaque from falling off to form blood clots, causing stroke, etc.

Beijing Deshengmen Hospital of Traditional Chinese Medicine - Gong Honghai - MD - Cardiovascular and Cerebrovascular Department - What causes myocardial ischemia.

Introduction: With the development of the times, in modern society, many people suffer from myocardial ischemia because of long-term fatigue or incorrect eating rules and work and rest habits. This disease may affect our daily life, and at the same time cause great impact and harm to our health, so when treating myocardial ischemia, if we want to prevent it, we need to have a good routine and diet in our long-term life, then in the treatment of patients with myocardial ischemia, it is necessary to avoid myocardial ischemia in daily life through the doctor's advice and instructions.

So let's talk about myocardial ischemia specifically.

Many people because of long-term lack of sleep and irregular diet, resulting in the body blood is relatively thin, often appear anemia and low blood pressure symptoms, then once the blood supply to the aorta is less, when the heart ischemia can not be timely **, there will be symptoms of myocardial ischemia. When the myocardium is ischemia, it will have a very big impact on our body, if it is not carried out in time, it may cause danger to our lives, and patients with myocardial ischemia will also cause some other complications because of the lack of attention to conditioning in daily life.

Many patients suffering from myocardial ischemia must pay attention to their diet in their daily life, and pay attention to eating more low-fat and high-fiber foods, so that the symptoms of psychological needs can be alleviated and prevention can be carried out at the same time. It is necessary not only to pay attention to diet, but also to have sufficient sleep time, ensure regular work and rest, and develop good living habits, which will alleviate and prevent the symptoms of myocardial ischemia.

To sum up, we can find that the new world will have a great impact on a person's life and health, so in our daily life, we should actively understand the knowledge of myocardial ischemia, which will not only help the recovery of the disease, but also prevent patients who have not suffered from myocardial ischemia.

It can be due to insufficient blood supply, coronary heart disease, or chest pain. Myocardial ischemia must be timely**, otherwise it will cause coronary heart disease, and there will be angina pectoris, which will bring unfavorable factors, there is no way to prevent the disease, and it will cause many problems.

It may be caused by insufficient blood**, or lack of oxygen, or it may be caused by angina. This condition can cause very serious symptoms of the disease, which can affect the heart, blood diseases, or coronary heart disease, and many problems.
