Coronary heart disease is the main force in the heart disease, it is absolutely the cardiology department of the “main disease”. It is also the disease that causes the most deaths of our residents, that is to say, coronary heart disease (cardiovascular disease) is the disease that causes the most deaths of our residents! Coronary artery distribution map Second, what is coronary heart disease? Coronary heart disease is due to lipid deposits in the original smooth arterial lining in the arterial lining of some similar atherosclerotic lipid accumulation of plaques, these plaques gradually increased caused by the narrowing of the arterial lumen, so that the blood flow is impeded, resulting in ischemia of the heart, resulting in angina pectoris, and other types of symptoms. In layman’s terms, it’s not that complicated: it’s the narrowing of the blood vessels supplying blood to the heart for various reasons, which leads to and causes all kinds of discomforts, and it’s called coronary heart disease. As shown in the figure below: normal is definitely not called coronary heart disease, 25% is called plaque, stenosis greater than 50% or more is called coronary heart disease. It turns out that coronary heart disease is not that complicated! It is because the cause is the narrowing of the blood vessels supplying the heart itself, so in many clinics, doctors will call coronary heart disease insufficient blood supply to the heart, the reason is also here. Having understood the definition of coronary heart disease, let’s talk about the types of coronary heart disease! Coronary heart disease is divided into five types, angina type, myocardial infarction type, arrhythmia type, asymptomatic type and sudden death type! Third, coronary heart disease will have those symptoms? Typical coronary heart disease most of the following symptoms 1, activity or after a full meal or chest pain in the anterior region of the chest or sternal pain, or tightness pain, and can be accompanied by a sense of neck tightness, can be radiated to the left shoulder, the left upper arm, lasts for several minutes, tens of minutes, can be relieved after rest. 2, physical activities (such as riding a bicycle, doing farm work, etc.), chest tightness, palpitations, shortness of breath, severe cases can not continue to carry out related physical activities, rest on their own to relieve. 3.Headache, toothache, epigastric pain, etc. related to exercise. 4. Those who experience chest pain and tightness when they are full, cold or have severe mood swings. Therefore, to confirm the diagnosis of coronary heart disease, absolutely not a sentence to diagnose! Fourth, how to confirm the diagnosis of coronary heart disease? Coronary heart disease diagnosis is the need for the right coronary artery imaging to diagnose, purely to an electrocardiogram or to a few words on the diagnosis of coronary heart disease is a little too hasty! Therefore, to diagnose coronary artery disease, we need to perform coronary angiography or coronary CTA to determine whether there is a narrowing of the coronary artery. Of the two, coronary angiography is the clearest, and is called the gold standard for coronary heart disease diagnosis.
