What is the difference between coronary heart disease, angina pectoris, and myocardial infarction?

Coronary heart diseaseAlso known as coronary atherosclerotic heart disease, it is generally divided into two main categories: chronic coronary disease and acute coronary syndrome. Myocardial infarction is an acute coronary syndrome, which includes acute myocardial infarction, unstable angina and sudden death, and angina pectoris, which includes stable angina and unstable angina.

Coronary heart disease is a general term, which is caused by the hardening of the arteries and blood vessels of the heart and become narrowed or even blocked by blood clots, and to a certain extent, myocardial ischemia will occur, and the four common types of coronary heart disease are angina, myocardial infarction, chronic heart failure and sudden death.

Angina pectorisIt is a clinical syndrome caused by acute and temporary ischemia and hypoxia of the myocardium caused by the increase of myocardial oxygen consumption on the basis of coronary atherosclerosis, but the blood supply of coronary arteries cannot increase accordingly.

Angina pectoris usually occurs due to increased exertional load, lasts less than 20 minutes, and is usually relieved by resting within 15 minutes or using nitrates.

Myocardial infarctionDeath is also based on coronary atherosclerosis, myocardial severe necrosis, coronary blood supply, a sharp reduction, interruption of blood supply, so that the corresponding myocardium severe and long-lasting acute ischemia caused.

The onset of myocardial infarction is generally more severe, the patient has a sense of impending death, and the attack generally has no cause, the duration is generally about 15 to 20 minutes or even longer, nitroglycerin has no effect, and the attack can be accompanied by changes in blood pressure, such as a drop in blood pressure, and even shock.

Can it still be cured?

Whether it is coronary heart disease, angina, myocardial infarction, these three diseases can not be fundamentally reversed, because atherosclerosis of blood vessels is a slowly developing and irreversible disease, leading to arteriosclerosis factors are: age, genetics, smoking, long-term hypertension, diabetes, irregular lifestyle, inactivity, high salt, high oil diet, etc., are the causes of arteriosclerosis. Many factors are beyond our control, such as age, genetics, etc.

Therefore, the current best is to control arteriosclerosis, delay the progression of the disease, delay the onset of the disease, and prolong the time of complications. thereby improving the quality of life.

Angina pectoris and myocardial infarction are usually caused by coronary heart disease, which generally manifests as symptoms of angina pectoris and symptoms of myocardial infarction. Symptoms of myocardial infarction are palpitation, shortness of breath, chest tightness, and myocardial necrosis. Angina pectoris symptoms are sudden pain in the heart that usually lasts for a few minutes and then radiates to the left arm.

Coronary heart disease, angina, and myocardial infarction should be examined for coronary blood vessels, usually with drugs**, acupuncture**, diet**, exercise**, drugs** with blood stasis, anti-thrombosis, anti-arteriosclerosis drugs**.

Angina pectoris and myocardial infarction are two types of coronary heart disease. The difference between angina pectoris and acute myocardial infarction: 1. The site of onset, angina pectoris often occurs after the middle and lower sternum, and acute myocardial infarction can also occur in the upper abdomen, neck, and jaw in addition to this part.

2. The nature of the pain, angina pectoris is mostly squeezing chest pain, and the pain of acute myocardial infarction is heavier than angina. 3. Inducing factors: angina pectoris often has predisposing factors such as emotional agitation, weight labor, and satiety, while acute myocardial infarction usually has no clear predisposing factors.

Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, but in fact, there are other ** (inflammation, spasticity, trauma, compression, embolism, congenital malformations, etc.) that cause coronary artery (coronary) lesions. Since coronary atherosclerosis is the most common (95% to 99%), we are talking about coronary heart disease now by coronary heart disease.

Angina pectoris is a clinical syndrome caused by insufficient coronary blood supply, acute and transient ischemia and hypoxia of myocardium. That is, it is a clinical manifestation of coronary heart disease. Similarly, angina pectoris is most commonly caused by coronary heart disease, but angina can also be caused by other causes of coronary artery disease, obstruction, or coronary ischemia.

Myocardial infarction is myocardial necrosis caused by continuous myocardial ischemia due to complete blockage of the coronary arteries. Similarly, coronary heart disease is the main cause but not the only one.

Coronary heart disease is also called coronary atherosclerotic heart disease. Among them, coronary heart disease includes acute coronary syndrome, and acute coronary syndrome includes acute myocardial infarction, so coronary heart disease and myocardial infarction are inclusional, and acute myocardial infarction refers to acute ischemic necrosis of myocardium, which is an acute and critical manifestation of coronary heart disease. For patients with acute myocardial infarction, the preferred method is coronary intervention, and if coronary intervention is not possible, it can be combined with coronary artery bypass grafting.

If the current patient has complex lesions that cannot be performed by surgery**, then only conservative drugs can be chosen**. Patients with coronary heart disease do not necessarily need to be combined with coronary intervention**, for example, patients with stable angina pectoris, generally speaking, oral medication is conservative**, and at the same time, it should be combined with lifestyle intervention to improve.

In fact, coronary heart disease includes myocardial infarction, which is a special type of coronary heart disease. As we know, coronary heart disease refers to coronary atherosclerotic heart disease, a series of symptoms caused by insufficient blood supply to the coronary arteries.

Angina pectoris is usually short-lived, mild, and often has paroxysmal pain in the precordial area. In acute myocardial infarction, the pain is very severe, and patients often sweat profusely, radiating to the left shoulder or back, accompanied by a sense of impending death.

Coronary heart disease includes myocardial infarction, which is also a special type of coronary heart disease. Coronary heart disease refers to a series of symptoms caused by insufficient blood supply to the coronary arteries.

Because the scope of coronary heart disease is relatively large, because coronary heart disease already includes myocardial infarction, it is also easy to distinguish.

Coronary heart disease is an abnormality in the metabolic function of the heart, and the blood cannot flow in and out of the heart normally. The difference between angina pectoris and myocardial infarction is that myocardial infarction is generally accompanied by the onset of hypertension, hyperlipidemia and other diseases, which is more serious, while angina pectoris is more sudden and generally does not have any symptoms.

To prevent the above cardiovascular and cerebrovascular diseases, we must do the following: light diet, more exercise, frequent examination, good health, and pay attention to our own problems.

It is a common heart disease, especially prominent in the elderly group, angina pectoris and myocardial infarction have different causes, you need to adjust your life and rest, do not stay up late, drink less, and eat lightly can be prevented.
