Who is myocardial ischemia more likely to occur in?

Three-high and obese people: If hypertension, hyperlipidemia, and hyperglycemia are not controlled in time, or the symptoms of obesity are gradually aggravated, coronary atherosclerosis and stenosis can be induced, thereby causing myocardial ischemia

After women enter menopause, with the decline of estrogen levels, the protective effect of estrogen on cardiovascular and cerebrovascular vessels is reduced, which will lead to atherosclerosis and stenosis of coronary arteries, which can easily cause myocardial ischemia. In addition, menopausal women are prone to mood swings, which can cause myocardial ischemia

Patients with symptomatic myocardial ischemia mainly present with discomfort and pain in the precordial area, and the symptoms in the precordial area will vary in different degrees of myocardial ischemia. Other common symptoms include arrhythmias, difficulty breathing, chest pain radiating to other areas, etc. Severe myocardial ischemia is often associated with arrhythmias and cardiac insufficiency, presenting with a variety of cardiac and systemic concomitant symptoms.

1. Typical symptoms.

1. Sullen pain in the retrosternal or precordial area, or constriction-like pain occurs during exertion or mental tension, and radiates to the left shoulder and left upper arm for 3 5 minutes, which can be relieved by itself after rest, accompanied by heavy sweating.

2. Chest tightness, palpitations, and shortness of breath occur during physical activity, which are relieved by themselves when resting.

3. Exercise-related sore throat, burning, tightness, toothache, etc.

4. Chest pain and tightness after full meals, cold, and drinking.

5. When the pillow is low at night, you feel chest tightness and breathlessness, and you need to lie in a high pillow position to feel comfortable; Sudden chest pain, palpitations, and difficulty breathing while asleep or lying flat during the day require immediate sitting or standing to relieve relief.

6. Palpitation, chest tightness, shortness of breath or chest pain and discomfort during sexual life or straining to defecate.

7. Sudden bradycardia, decreased blood pressure or syncope.

2. Accompanying symptoms.

Mild myocardial ischemia generally has no accompanying symptoms, but as the degree of ischemia increases, arrhythmias, cardiac insufficiency and other manifestations will occur, which can manifest as cardiovascular system, digestive system and systemic symptoms.

1. Arrhythmia-related symptoms: It can be seen in a variety of myocardial ischemic diseases, with myocardial infarction and ischemic cardiomyopathy being the most common, which can have no obvious manifestations, or manifest as chest tightness, palpitations, and may be accompanied by symptoms such as general fatigue, dizziness, and syncope.

4. Other systemic symptoms: 1. Fever: seen in myocardial infarction, it is a reaction caused by the absorption of necrotic substances, which generally does not exceed 39 degrees Celsius, and often appears 1 2 days after infarction and lasts for about 1 week.

2. Shock: It is mainly caused by large-scale myocardial infarction, and the cardiac output is sharply reduced, which can be manifested as symptoms such as decreased blood pressure, irritability, paleness, clammy coldness, rapid pulse, sweating, and apathy.

3. Other symptoms.

Patients without typical symptoms only experience stomach discomfort, nausea, or toothache or cervical spine pain.

What we call myocardial ischemia often refers to coronary atherosclerotic heart disease, coronary artery stenosis, resulting in some clinical conditions in which the relative blood supply to the myocardium is insufficient. Its clinical manifestations are mainly characterized by intermittent chest tightness and chest pain, which can be relieved by rest, and is generally related to activity.

It depends on the degree of atherosclerotic heart stenosis of the coronary arteries, and myocardial ischemia caused by narrower coronary artery stenosis can be treated with medications. If the coronary artery is severely stenosis, we need to open the blood vessels, which we call revascularization**, we can consider the application of interventional means**, with balloon dilation or stent implantation, to make the stenosis unobstructed, the myocardium will be improved, and the patient will be improved. Or enter the surgical bypass technique, so that myocardial ischemia is improved, and the patient will also get a significant improvement after recovery.

What is myocardial ischemia?

Myocardial ischemia mainly refers to the reduction of blood outflow from the heart, and the metabolism of the heart is abnormal, which cannot well support the daily work of the heart. In fact, many times, we have myocardial ischemia, because we suffer from some cardiovascular and cerebrovascular diseases, such as coronary atherosclerosis, which will cause us to have myocardial ischemia. What other diseases can cause myocardial ischemia?

1. Low blood pressure

When blood pressure is too low, it will lead to a decrease in the blood supply to the aorta, which in turn will lead to myocardial ischemia, if this condition exists, it is necessary to strengthen physical exercise, enhance the body's regulatory function, and properly supplement nutrition to stabilize blood pressure to avoid recurrence of myocardial ischemia.

2. Coronary heart disease

Coronary artery stenosis and blockage is also one of the diseases that lead to myocardial ischemia, and the main disease that causes coronary atherosclerosis is coronary heart disease, so coronary heart disease is also one of the important causes of myocardial ischemia. It is recommended that patients always have a quick-acting heart-saving pill by their side in case of emergency.

3. Other cardiovascular diseases

For example, blood thickness, valvular heart disease, and myocardial disease itself lead to a decrease in the amount of blood in the heart, insufficient blood supply to the heart, and a gradual increase in oxygen demand, resulting in myocardial ischemia. Or there is hyperlipidemia, hypertension, and hyperglycemia, which can lead to blockage of blood vessels, and excessive lipid substances in blood vessels can induce coronary heart disease, resulting in myocardial ischemia.

4. Common symptoms of myocardial ischemia

1. Toothache, headache or leg pain during or after exercise, and there is no organic lesion in the painful area.

2. When doing a moderate amount of physical activity, shortness of breath, palpitations or chest tightness will occur, which can be relieved by itself after a little rest.

3. When watching thriller movies and TV dramas, feeling cold or having a full meal, people with symptoms of palpitations and chest pain should be vigilant.

4. Sullen pain in the precordial area or retrosternal area during mental tension or exertion, which can also be constricted, and radiate to the left shoulder and left upper arm, the pain lasts for 3-5 minutes, and can be relieved by itself after appropriate rest.

5. When you hear the noise, you will feel chest tightness or panic, and the discomfort will be reduced after the noise disappears.

6. When sleeping, the pillow will have a feeling of chest tightness and breathlessness, and the height of the pillow and the lying position need to be adjusted to feel comfortable; Sudden palpitations, chest pain, or difficulty breathing during the day when lying flat or asleep requires immediate sitting or standing to relieve relief.

7. In the case of no exercise, there is irregular pulse for many times, and there are symptoms of bradycardia or hypercardia of unknown reasons.

8. When straining to defecate or having sex, uncomfortable symptoms such as chest tightness, palpitation, shortness of breath or chest pain often occur.

The most common cause of myocardial ischemia is coronary atherosclerosis, followed by inflammation (rheumatism, syphilis, Kawasaki disease, and vasoangiitis obliterans, etc.), spasticity, embolism, connective tissue diseases, trauma, and congenital malformations. Epidemiological studies have found that important risk factors associated with atherosclerosis are hyperlipidemia, hypertension, diabetes, smoking, obesity, increased homocysteine, low physical activity, advanced age, and male sex.

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.

Myocardial injury, coronary artery stenosis, etc. have caused myocardial ischemia, ginseng gui capsule has the effect of blood circulation and blood stasis, can improve myocardial ischemia.

1. Narrowing of the vascular lumen including thickening of the tube wall 2. Insufficient blood flow to the myocardium due to vasoconstriction and other reasons.

Caused by narrowing or spasm of blood vessels, there are many conditions of narrowing of blood vessels, the most common being atherosclerosis.

Myocardial ischemia, also known as coronary heart disease, is mainly caused by insufficient blood supply to the heart muscle tissue caused by coronary atherosclerosis or spasticity.

Drinking, staying up late a lot, lack of necessary physical exercise, and not having good rest are the main things.

Caused by coronary atherosclerosis or by spasm of the coronary arteries.

Myocardial ischemia is a decrease in blood perfusion to the heart, resulting in a decrease in the heart's oxygen supply. A pathological state in which myocardial energy metabolism is abnormal and cannot support the normal functioning of the heart. The energy required for heart activity is almost entirely provided by aerobic metabolism, and the rate of oxygen uptake by the myocardium is high even at rest.

Under normal circumstances, the body can promote the relative constant supply and demand of blood through its own regulation, so as to ensure the normal operation of the heart. When some reason leads to myocardial blood imbalance, it causes myocardial ischemia in the true sense.

There are many reasons that can cause myocardial ischemia, such as decreased blood pressure, reduced blood supply to the aorta, and blocked coronary arteries, which can directly lead to a decrease in blood supply to the heart. Valvular heart disease, changes in blood viscosity, and myocardial disease can also reduce the blood supply to the heart, the most common cause of which is coronary atherosclerosis.

Secondly, inflammation, spasticity, connective tissue diseases, trauma and congenital malformations, etc., which are important risk factors associated with atherosclerosis, such as hyperlipidemia, hypertension, diabetes, smoking, obesity, low physical activity, advanced age, etc.

Hello, the causes of myocardial ischemia are as follows:

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.

Clinically, the main and most common cause of myocardial ischemia is coronary (and occasionally pulmonary) stenosis. And the main cause of coronary artery stenosis is atherosclerosis. Heart disease caused by coronary atherosclerosis is often referred to as coronary heart disease.

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

I hope the above reply is helpful to you and I wish you good health.

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

Coronary artery stenosis is a narrowing of the lumen of the blood vessels supplying blood to the heart and a decrease in blood flow, resulting in insufficient blood supply and oxygen supply to the heart muscle. Suggested take: "Heart Link" can improve myocardial insufficiency.

Causes of myocardial ischemia.

1. Excessive myocardial blood consumption. 1. Excessive work; 2. Excessive pressure; 3. Excessive mood swings;

4. Poor blood circulation; 5. Regurgitation of the valve.

2. The blood supply to the myocardium is too small. 1. Volume depletion; 2. The total infusion of the heart is small; 3. Centripetal muscle.

The blood vessels supplying blood are not blocked; 4. The circulating blood flow is not smooth.

Coronary arteries in the heart are narrowed or blocked by plaque, resulting in insufficient blood supply to the heart and heart.
