Coronary arteries are important blood vessels that supply blood to the heart, when due to various reasons lead to atherosclerosis, causing narrowing or occlusion of the vascular cavity, patients will have chest pain, chest tightness and other discomfort, this heart disease is called coronary heart disease, its essence is insufficient blood supply to the heart caused by myocardial ischemia, hypoxia or necrosis.
Surgical treatment of coronary heart disease
Treatment of coronary heart disease includes lifestyle improvements, medications, and surgery. For severe coronary heart disease, or patients with ECG examination with ST-elevated myocardial infarction, time is life, it is recommended that such patients be detected early, hospitalized early, and the treatment method is mainly thrombolytic and interventional therapy, which can restore the blood perfusion of the myocardium as soon as possible, thereby reducing complications and mortality.
The so-called interventional therapy, in the popular sense, mainly includes the heart stents familiar to the common people (percutaneous coronary intervention) and heart bypass (coronary bypass transplantation). Among them, bypass surgery requires open chest, mainly for multi-branch, severe coronary stenosis, today we will focus on the postoperative precautions of stent surgery.
Can stents cure coronary heart disease?
Patients often ask, why do you need to take the drug for a long time after implantation? Can implanting a cardiac stent cure coronary heart disease? First of all, we must know that implanting stents is a method of coronary heart disease, but implanting stents can only temporarily solve the problem of narrowing blood vessels, and the most fundamental cause of atherosclerosis cannot be solved by stents. Therefore, after doing the stent, it is still necessary to take the medicine for a long time.
Generally after the stent surgery, the usual medication is aspirin and clopidogrel, these two drugs are anti-platelet aggregation drugs, mainly because after the stent implantation, it has an endothelial process, in this process, in order to prevent the formation of blood clots, to ensure the surgical effect, to insist on taking the above drugs.
In addition, there are statins, mainly to prevent the aggravation of coronary atherosclerosis, if we can reduce low-density lipoprotein cholesterol (LDL-C) to 1.0mmol / L, it can be eliminated. Generally after the stent, we require the patient's low-density lipoprotein cholesterol (LDL-C) to reach 1.4mmol/L, which can stabilize the plaque, will not form new blood clots, our condition is also stable, and the incidence of myocardial infarction will be greatly reduced.
How long do you take stent double antibody drugs?
In the beginning, because some patients did not take aspirin, there were also some medical studies to confirm the initial conclusion that if you do not take aspirin or clopidogrel after the stent, it will cause thrombosis in the stent, but it will cause higher mortality. So, how long do you have to take a dipal antibody?
Patients are generally advised to take dual antiplatelet therapy for one year, and then decide whether to discontinue the drug after professional evaluation. If the patient takes statin drugs and has diabetes or hypertension at the same time, it is necessary to take related drugs to control blood sugar and blood pressure at the same time, which is conducive to disease control for atherosclerosis.
After the stent is done, it is recommended that patients come to the hospital at intervals of one month, three months, half a year, and twelve months for re-examination, including electrocardiogram, myocardial ischemia, blood routine, etc., to determine whether there is a decrease in platelets and a decrease in white blood cells.
In addition, to review the liver and kidney function, long-term use of drugs may have a certain impact on liver and kidney function, if once the liver and kidney damage is caused, it should be found in time and treated in time. Blood lipids are also items to be reviewed, mainly to see whether low-density lipoprotein cholesterol (LDL-C) has reached the standard, if not up to the standard, it is necessary to combine ezezé mebra to lower blood lipids on the basis of statins, so that the effect of treatment can be guaranteed, so that patients can ensure a good quality of life.
