Is myocardial ischemia coronary heart disease?Does myocardial ischemia necessarily mean coronary hea

Myocardial ischemia is not the same as coronary heart disease. Myocardial ischemia refers to abnormal metabolism of myocardial cells caused by ischemia and hypoxia;Coronary heart disease refers to structural abnormalities in the coronary arteries, such as coronary atherosclerotic plaques, leading to narrowing of the lumen of the coronary arteries and abnormal coronary artery function, such as spasm of the coronary arteries, resulting in reduced blood flow to the coronary arteries and ischemia and hypoxia of myocardial cells. Coronary heart disease is usually associated with cardiomyocytic ischemia, but cardiomyocytic ischemia is not necessarily coronary artery disease.

The two concepts should not be confused.

Myocardial ischemia is not necessarily coronary artery disease. Myocardial ischemia can be caused by a variety of causes, and in addition to coronary heart disease, some other diseases can also cause symptoms of myocardial ischemia. Therefore, patients cannot determine that they have coronary heart disease based on the single symptom of myocardial ischemia.

Under normal circumstances, after the formation of coronary atherosclerosis, patients may have varying degrees of myocardial ischemia, but if the patient has long-term hypertension, hyperglycemia, excessive obesity, or myocardial oxygen supply and aerobic imbalance, severe anemia, rheumatic heart disease, coronary spasm, coronary artery muscle bridge and other problems, it may also induce myocardial ischemia, at this time, patients can have chest tightness, chest pain, precordial pain, sweating and other symptoms. If the patient suspects that his myocardial ischemia symptoms are caused by coronary heart disease, he or she needs to make a diagnosis based on echocardiography, coronary angiography, coronary artery CT and other related diagnoses. If confirmed, patients need to take statin anticoagulants or other appropriate drugs under the guidance of a medical professional**.

In daily life, patients with myocardial ischemia need to avoid staying up late, drinking, smoking, etc., and avoid excessive activity to avoid symptoms**. At the same time, patients need to pay attention to keeping warm and preventing cold, so as to promote physical recovery.

Coronary atherosclerotic heart disease, referred to as coronary heart disease, is a heart disease caused by atherosclerotic lesions in the coronary arteries, resulting in narrowing or blockage of the lumen of the blood vessels, resulting in myocardial ischemia, hypoxia or necrosis.

Classification of coronary heart disease.

1) Insidious type: the patient has coronary arteriosclerosis, but the lesion is mild or has good collateral circulation, or the patient has a high pain threshold and no pain symptoms.

2) Angina pectoris: on the basis of coronary artery stenosis, due to the increase of myocardial load, causing myocardial abrupt, transient ischemia and hypoxia clinical syndrome.

3) Myocardial infarction type: on the basis of coronary artery lesions, a sharp reduction or interruption of coronary blood supply occurs, so that the corresponding myocardium is severely and persistently acute ischemia leading to myocardial necrosis.

4) Heart failure type: (ischemic cardiomyopathy) myocardial fibrosis, long-term insufficiency of blood supply to myocardium, nutritional disorders and atrophy of myocardial tissue, or fibrous hyperplasia after large-scale myocardial infarction.

5) Sudden death type: it is the most serious one, the occurrence of cardiac arrest is due to the occurrence of coronary artery spasm or embolism on the basis of atherosclerosis, resulting in acute ischemia of myocardium, resulting in local electrophysiological disorders, causing temporary severe arrhythmia leading to sudden death.

Therefore, myocardial ischemia is the main pathological basis of coronary artery disease.

The early manifestations of myocardial ischemia in coronary heart disease are tinnitus, chest tightness and chest pain, and if there are no such symptoms before, you should see a doctor.

Early manifestations include precordial pain, mostly episodic colic or squeezing pain. The pain radiates from the precordial area to the left shoulder and is relieved by nitroglycerin.

Typical myocardial infarction is persistent chest pain that is not relieved, squeezing pain, accompanied by chest tightness, breathlessness and sweating; However, there are many myocardial infarctions that are not so typical, and there are many myocardial infarctions, which may just be persistent toothache, headache, back pain, shoulder pain, upper abdominal pain, chest pain, breath-holding, pharyngeal tightness, sweating and other symptoms, all of which may be myocardial infarction.

There is shortness of breath, chest tightness, chest pain, and some people will radiate to the neck after the pain, and they will feel tightness in the neck, but the degree of this symptom is often mild in the early stage.

It was found that coronary heart disease hurts once every 24 hours in 10 days.
