What is myocardial insufficiency and what can myocardial insufficiency cause?

The heart needs to be well supplied with energy. The blood supply of the heart itself has two significant characteristics: 1. Although the weight of the heart is less than 1 of the body weight, it needs 20 of the blood volume of the whole body to meet the blood supply of the heart itself; 2 In order to meet the special needs of the heart's blood supply, the human body also has its own blood supply system to ensure adequate blood supply.

The heart has its own blood supply system, which is the coronary circulation.

Myocardial ischemia is mainly due to changes in the substances contained in the blood and pathological changes in the lumen of blood vessels. Most of them are caused by hyperlipidemia and hypercholesterolemia caused by life factors such as unreasonable diet and too little exercise. Cholesterol in the blood is divided into high-density lipoprotein cholesterol (referred to as high-density alcohol) and low-density lipoprotein cholesterol (referred to as low-density alcohol).

In the blood, in addition to supplying the cells, the excess will be deposited in the inner wall of the arterial blood vessels, so that the inner wall of the blood vessels will start from non-smooth changes until the formation of atheromatosis, causing the vascular passage to become narrow or even blocked. Therefore, low dense alcohols are noxious cholesterol. Nitrol will carry the cholesterol in the blood to the liver, convert, and then excrete it through the gallbladder into the intestines, which is protective cholesterol.

In addition, advanced age, high blood pressure, diabetes, obesity, mood swings, tobacco and alcohol habits, and adverse reactions of certain drugs can cause vascular changes leading to myocardial ischemia and intravascular thrombosis.

Cardiovascular disease caused by myocardial ischemia, often asymptomatic in the early stage of the disease, gradually shortness of breath, shortness of breath, shortness of breath, the original three or four floors did not feel much, now just on the second floor there is palpitation, shortness of breath, rapid heartbeat, indicating insufficient myocardial blood supply, heart function weakened, which will be an early hint of cardiovascular disease. If you feel fatigue and weakness and paroxysmal chest pain, it is already a relatively obvious symptom of cardiovascular disease.

Myocardial insufficiency, also known as myocardial ischemia, is mostly due to some clinical symptoms caused by coronary heart disease, that is, coronary atherosclerotic heart disease, such as chest tightness, dyspnea, shortness of breath on exertion, such as many elderly patients who climb stairs or walk for a long time, and have some symptoms of dyspnea.

Hello: It is caused by blood vessel blockage or spasm of ** heart nutrition, in this case, it is recommended to rule out the possibility of coronary heart disease with 64-row CT examination, I hope mine can help you. ydz

It's just that there is not enough blood to supply the heart.

Symptomatic patients may have palpitations, angina, dyspnea, etc., and with the aggravation of the condition, they can also be complicated by heart failure, arrhythmia, etc., and even sudden cardiac death, which seriously threatens the health and life of patients.

The coronary arteries are the blood vessels of the heart itself, divided into left and right coronary arteries, originating from the root of the aorta, when the blood flow to one or more coronary arteries is reduced, it can lead to insufficient blood supply to the heart muscle.

Extended Materials. Cardiac muscle is a type of muscle tissue made up of heart muscle cells. Cardiomyocytes in a broad sense include specially differentiated cardiomyocytes that make up the sinus node, intraatrial tract, atrioventricular junction, atrioventricular bundle (i.e., Hiss bundle), and Purkinje fibers, as well as general atrial muscle and ventricular myocardial working cells. The first five species make up the cardiac pacing conduction system, which contains little or no myofibrils, so none of them have systolic function; However, they are autonomic and conductive and are the functional basis for the autonomic activity of the heart; The latter two are contractile and are the functional basis of cardiac contractile activity.

Cardiomyocytes are short, columnar, and generally have only one nucleus, while skeletal muscle fibers are multinucleated cells. There is a leap disc structure between the cardiomyocytes. The cell membranes are intercalated and differentiated to form desmosomes, which are tightly connected to each other, but there is no protoplasmic continuity between cardiomyocytes.

Myocardial tissue was mistaken for syncytia in the past, and electron microscopy studies found a distinct septum between myocardial cells, which was corrected.

The intercalary disk of the myocardium facilitates the transfer of excitatory from cell to cell. On the one hand, due to the low impedance of the structure to the current, the excitatory wave is easy to pass through; On the other hand, because of the gap connection, there are 15 20 angstroms hydrophilic tubules inside, which can allow calcium ions and plasma to permeate and transport. Therefore, although the normal atrial muscle or ventricular myocytes are separated from each other, they are excited almost at the same time and contract synchronously, which greatly improves the efficiency of myocardial contraction, and functionally reflects the characteristics of syncytia, so it is often called "functional syncytia".

The so-called myocardial insufficiency: it is the blood supply of the heart itself, and the human body also has its own blood supply system to ensure adequate blood supply in order to meet the special needs of the heart blood supply. The heart has its own blood supply system, which is the coronary circulation.

Insufficient blood supply to the myocardium will lead to hypoxia of the myocardium and weakening of heart function, which is the number one enemy that endangers human health. Myocardial ischemia is mostly caused by hyperlipidemia and hypercholesterolemia caused by life factors such as unreasonable diet and too little exercise, which will be deposited on the inner wall of arterial blood vessels until the formation of atheromatosis, resulting in narrowing or even blockage of blood vessels, and eventually evolving into serious diseases such as coronary heart disease. Controlling calories, controlling the quality and quantity of fat intake, controlling sugar intake, and appropriately increasing dietary fiber intake can effectively avoid myocardial insufficiency.

Myocardial insufficiency, also known as myocardial ischemia, is mostly due to some clinical symptoms caused by coronary heart disease, that is, coronary atherosclerotic heart disease, such as chest tightness, dyspnea, shortness of breath on exertion, such as many elderly patients who climb stairs or walk for a long time, and have some symptoms of dyspnea.

Hello, according to your description, there are many causes of insufficient blood supply to the myocardium: arteriosclerosis, especially coronary arteriosclerosis, is the main cause of myocardial ischemia.

Hello, this condition is more common in coronary heart disease myocardial ischemia, related to atherosclerosis, more common in middle-aged and elderly people, combined with hypertension, diabetes and hyperlipidemia are more likely to occur.

Myocardial ischemia refers to a pathological state in which the blood perfusion of the heart is reduced, resulting in a decrease in oxygen supply to the heart, abnormal myocardial energy metabolism, and inability to support the normal work of the heart. Myocardial ischemia seriously endangers the health of middle-aged and elderly people, in recent years, with the improvement of living standards, coronary atherosclerosis shows a trend of younger people, and some young people aged 20-30 also have myocardial ischemia.

Myocardial ischemia usually occurs after the age of 40 years, and the average prevalence is about . With the improvement of people's living standards, the prevalence of myocardial ischemia in China is increasing year by year. Myocardial ischemia is a common and frequent disease in middle-aged and elderly people, people at this age, in daily life, if the following conditions occur, they should seek medical attention in time and diagnose as soon as possible.

1) Retrosternal or precordial pain during exertion or mental tension, or constriction-like pain, which radiates to the left shoulder and left upper arm for 3-5 minutes, and is relieved by itself after rest, accompanied by heavy sweating. (2) Those who have chest tightness, palpitations, and shortness of breath during physical activity, and are relieved by themselves when resting. (3) Exercise-related sore throat, burning, tightness, toothache, etc.

4) Those who have chest pain and tightness after eating, cold, and drinking. (5) Those who feel chest tightness and breathlessness when sleeping with a low pillow at night, and need a high pillow to lie down to feel comfortable; Those who are asleep or have sudden chest pain, palpitations, or difficulty breathing when lying flat during the day, and need to sit up or stand up immediately to relieve it. (6) Palpitation, chest tightness, shortness of breath or chest pain and discomfort during sexual life or straining to defecate.

Angina pectoris, arrhythmia caused by insufficient blood supply to the heart, and myocardial infarction can occur in severe cases, causing large-scale necrosis of the myocardium, which is life-threatening; The main and most common cause of myocardial ischemia** is coronary artery stenosis. According to the number of blood vessels, the degree and length of stenosis of the coronary artery that causes myocardial ischemia and the characteristics of the lesion, the best plan should be formulated and the method of selection (surgery, intervention, drug) should be provided to provide the most scientific basis. At the same time, it is low in fat and high in fiber, avoid emotional agitation, maintain adequate sleep, develop good living habits, and do not overwork.

What is myocardial insufficiency?The doctor gave a clear answer, so let's take a look.

Medications**, stents or bypasses, etc. Mild myocardial ischemia can be treated with Danshen Dripping Pills and nitroglycerin to improve symptoms!Myocardial ischemia is a common ECG manifestation, and common diseases are coronary heart disease and cardiomyopathy

It is recommended that you go to the hospital to check the electrocardiogram and take a film, my symptoms you refer to, I am also chest tightness, sometimes I am out of breath, my left shoulder and heart sometimes hurt, the root of the nail will be purple, I am the myocardial blood supply is insufficient, I also checked the ECG and took a film, the ECG said that the heart rate is too fast, and the ** taken said that it is not abnormal. I think you should be, but you should still check it, I am now a combination of Chinese and Western medicine, that is, some blood and qi supplements, some Chinese medicine such as ejiao and the like, and, I think you have to go to the cardiovascular and cerebrovascular department.

Insufficient blood supply to the myocardium will lead to ischemia and hypoxia of the myocardium, which will directly lead to symptoms such as chest tightness and chest pain, and long-term ischemia can also be used to cause heart rhythm to cause palpitations and palpitations and other symptoms Common in coronary heart disease and myocarditis Cardiomyopathy and other diseases It is best to be clear first** Different ** The drugs used are not the same Yudan wishes you a speedy health.

The heart socket is uncomfortable, the heart socket hurts left and right, the throat is uncomfortable, the feet and hands are weak and incompetent, is it a heart disease?

Your stomach cold can be determined that there are no clear signs of insufficient blood supply to the heart muscle.

**Purpose: 1. Nourish the heart.

2. Nourish the stomach. Recommendations:

1. Long-term use of Danshen tablets (do not compound Danshen tablets, because the "borneol" in the compound is harmful to the stomach) 2. Long-term drinking of Shengmai Drink Oral Liquid (Ginseng Formula).

3. 15 grams of hawthorn is decocted in water each time, and the residue can be chewed as much as possible (2 times a day) 4. Long-term jade screen powder or capsule (health care Chinese medicine to enhance immunity, you can choose not to eat, but it is better to eat).

Avoid eating: 1. Radish.

2. Mung beans. 3. Milk.

4. Crabs. Note:

People with cold stomachs are not suitable for taking drugs that clear the fire such as Yinqiao tablets and bezoar detoxification tablets.

You can take Shuanghuanglian oral liquid or capsule plus gram sensitive tablets, a combination of Chinese and Western**.
