A distinctive feature of coronary heart disease patients is that although they suffer from the same disease, the severity of the disease varies greatly. In mild cases, there are no conscious symptoms and the patient can work or study as usual; in slow cases, the disease can last for decades; in severe cases, the disease starts suddenly and progresses rapidly, and if not rescued in time, the patient can die suddenly within a few hours. In view of this feature, help you understand the method of identifying the priority of coronary heart disease. A, look at the type of disease 1, myocardial infarction: if the infarcted myocardium is large and extensive, the patient will have a life-threatening. 2, angina: exertional angina is mostly the precursor of myocardial infarction, and post-infarction angina can occur again at any time, which should be given special attention and active treatment. 3, heart failure: indicates that the condition has entered the advanced stage, the long-term prognosis is not good. 4.Hidden coronary artery disease: It is a milder type. 5.Sudden death: This type of patient can be asymptomatic normally, and often die due to cardiac arrest. 6.Cardiac arrhythmia: the manifestations are diverse and vary in severity, the milder ones work and study as normal, the more severe ones can be life-threatening. If there are no obvious conscious symptoms, the condition is mild; if angina pectoris, chest tightness and severe arrhythmia often occur, it indicates a serious condition. If the patient’s electrocardiogram changes significantly, with more serious myocardial ischemia, myocardial strain, arrhythmia, etc., it indicates a more serious condition; on the contrary, a normal electrocardiogram in a quiet state indicates a less serious condition. Fourth, look at the structure of the heart Through modern diagnostic techniques such as coronary angiography, the narrowing of coronary artery branches can be understood. If the lumen of the diseased artery branch is severely narrowed, it mostly indicates a more serious condition. If the left ventricle of the heart is enlarged, it also indicates a serious condition. If the patient’s blood pressure is significantly elevated, and the effect of lowering blood pressure is not good, or fluctuates greatly, it is not good for recovery. High blood lipids will also accelerate the process of atherosclerosis. Stroke and diabetes mellitus are closely related to coronary heart disease. If a patient suffers from stroke or diabetes at the same time, the condition is more serious and the joint prevention and treatment of the three diseases should be strengthened. If the patient’s heart function is normal and he/she is not restricted from doing moderate physical activities and does not experience palpitations, shortness of breath and other conscious symptoms, the condition is mild; on the contrary, the condition is severe. If someone in the patient’s immediate family, especially parents or siblings, died of coronary heart disease, stroke or diabetes and was younger (less than 60 years old) at the time of death, the patient should be alerted and treatment should be strengthened. Early detection and early treatment of coronary heart disease is important. Prevention of coronary heart disease usually develop good living habits, quit smoking and drinking, and combine work and rest. Receive regular health checkups and seek medical attention without delay once coronary heart disease appears.
