Understanding coronary heart disease

Coronary heart disease, the full name is coronary atherosclerotic heart disease. Unlike transient diseases such as colds and fevers, atherosclerosis is like a difficult little devil. It is a progressive, persistent and even lifelong disease! The essence of coronary heart disease is that atherosclerotic plaques emerge in the coronary arteries. Once these plaques cause trouble, the blood vessels of the heart become narrower, the blood supply and oxygen supply to the myocardium are insufficient, and then symptoms such as chest pain and malignant arrhythmia pop up. The occurrence of coronary heart disease is related to many factors, among which lifestyle is a very important influencing factor. If there is a history of high blood pressure and coronary heart disease at a young age in the family, the chance of getting the disease is very high; from middle-aged to elderly age, the probability of getting the disease is even higher; and those who often eat salty, fatty meat, fried foods, but eat less vegetables, coupled with bad lifestyle habits such as smoking, drinking, and not liking to exercise, may accidentally suffer from coronary heart disease.

Limitations of the role of stents

Some people say that coronary heart disease is not scary, and that a stent can be placed to open the blood vessels. In fact, stents are only one of the means of local vascular repair! It can open narrow blood vessels and make the lumen larger, which can improve the blood supply and oxygen supply to the myocardium and make patients with coronary heart disease more comfortable. However, stents have no therapeutic effect on atherosclerosis itself, nor can they reverse coronary artery vascular lesions, let alone fundamentally treat coronary heart disease.

Having a stent installed does not mean that coronary heart disease is completely cured. It just means that the symptoms of chest tightness and chest pain may be relieved and the risk of sudden death is reduced. Although stent implantation can effectively expand the narrowed blood vessels and allow the myocardium to regain blood and oxygen supply, the lesions of the coronary arteries are already there and cannot be reversed. Moreover, a stent is generally only about 1 to 4 centimeters, while the length of the coronary artery of the heart is far more than this length. Therefore, after the stent is implanted, in addition to the possibility of re-stenosis inside the stent, other parts without stents may also become narrow. Therefore, even if a stent is placed for coronary heart disease, coronary heart disease is not completely cured! If the root cause of coronary heart disease, atherosclerosis, is not fundamentally controlled, the chance of recurrence of vascular blockage or even myocardial infarction is very high.

A study investigated patients with coronary heart disease and myocardial infarction in the cardiac intensive care unit and found that more than 60% were recurrent patients, which is enough to illustrate the importance of long-term management of coronary heart disease, especially post-stent management.

Standardized long-term treatment is required after stent implantation

Therefore, after stent implantation, patients must also carry out secondary prevention of coronary heart disease, quit smoking and drinking, take lipid-lowering, antiplatelet, and anti-myocardial ischemia drugs for a long time, and maintain good blood pressure and heart rate. Combined with EECP treatment, better treatment effects can be achieved.
