Coronary heart disease, angina pectoris, myocardial infarction, all three have a relationship?

We have talked about the difference between coronary heart disease, angina pectoris and myocardial infarction. Today, what is the relationship between coronary heart disease, angina pectoris and myocardial infarction? All three are cardiovascular diseases, all of which can have a serious impact on the patient's body. Is there a connection between the three? Let's take a look at this issue.

Coronary heart disease, angina pectoris, myocardial infarction, all three have a relationship?

Coronary heart disease is the abbreviation for coronary atherosclerotic heart disease. The heart beats all the time and needs a lot of oxygen and various nutrients, but they are not taken directly from the blood in the heart chamber, but by the left and right sides of the heart called the coronary artery (its shape seems to be one The top hat buckles on the heart, hence the name of the blood vessels supplied. If the two blood vessels are narrowed due to various reasons (such as atherosclerosis), blood flow is not smooth, and the heart muscle does not get enough blood nutrition, myocardial ischemia occurs. This is coronary heart disease, also called deficiency. Bloody heart disease.


According to the clinical symptoms, coronary heart disease is divided into asymptomatic myocardial ischemic coronary heart disease, angina pectoris coronary heart disease, myocardial infarction coronary heart disease, heart failure and arrhythmia coronary heart disease and sudden death coronary heart disease, of which angina pectoris And myocardial infarction coronary heart disease is the most common.

The relationship between angina pectoris and coronary heart disease: angina pectoris is a group of syndromes caused by acute transient myocardial ischemia and hypoxia. In the case of coronary heart disease, due to poor blood supply to the heart muscle, too much metabolites (such as lactic acid) accumulated in the myocardium can not be transported away. These products can stimulate the afferent sympathetic nerves of the heart and pass into the brain to produce pain, so angina is Caused by myocardial ischemia, it is an important symptom of coronary heart disease.

Relationship between myocardial infarction and coronary heart disease: Myocardial infarction is a critical symptom of coronary heart disease. It is often based on frequent and exacerbated angina pectoris, and there are cases of sudden myocardial infarction with no history of angina. When the larger branch of the coronary artery is completely occluded (thrombosis), the myocardium supplied by this blood vessel is necrotic due to lack of blood nutrition, which is called myocardial infarction. Therefore, myocardial infarction is also the most serious consequence of coronary heart disease.

Through the above explanation, I believe that everyone has a preliminary understanding of the relationship between the three. Therefore, when the symptoms of angina pectoris are present, they should be treated actively in time. Otherwise, with the development of the disease, myocardial infarction may develop, causing serious consequences and even life-threatening.
