cardiac stent implantation is a common treatment method for coronary heart disease in recent years. It is one of the preferred options for opening restenosis blood vessels and undergoing PCI treatment. More than 75% of patients with coronary vascular stenosis are generally treated with stent placement.
cardiac stent implantation is mainly to place the arterial catheter at the opening of coronary artery through minimally invasive method. After injection of contrast agent, the coronary artery is observed and whether there is stenosis of the lumen is observed. If there is severe stenosis or even occlusion, you can consider putting a stent locally and stretching the stenosis or occlusion section to improve the blood flow of coronary artery and alleviate the symptoms of angina pectoris or myocardial infarction. However, after receiving cardiac stent implantation treatment, some patients still do not improve significantly by chest tightness and chest pain, which is because cardiac stent implantation still has "not good at work".
stent cannot solve the problem of microvascular damage
stent can open the large blood vessels of the heart and win time for saving lives. However, between the large blood vessels in the heart and the cardiomyocytes, there are still dense microveses, which are the "last mile" that transports blood to the cardiomyocytes.
After the large blood vessel is blocked, many of the microvascular connected to it may have been necrotic due to ischemia and hypoxia. In this way, even if the large blood vessels are opened, the blood still cannot be effectively transported to the cardiomyocytes, so the symptoms of chest tightness and chest pain are still not well improved. The phenomenon of is called "no reflux after reperfusion." or when the stent clears the large blood vessels, the sudden recovery of blood flow will violently impact and damage the microvessels, and will cause "reperfusion damage".
The place where the stent is placed may block
Stent surgery cannot be "one and for all". It can clear the blood vessels that are blocked or are about to be blocked, but it does not mean that this blood vessel or this part will not be stenosis or blockage again. stent means a foreign object is placed in the blood vessel. Over time, the place where the stent is placed will be blocked again. , especially , blood lipids , and abnormal blood viscosity are more likely to occur.
In addition, the arterial blood vessels in our human body are a large system, and the formation of atherosclerotic plaques will not occur only in one place. place the stent to clear the blood vessels in the blocked area, but the blood vessels in other places may also have plaques or even blockage again.
Two things to pay attention to after installing the bracket
Putting a stent on the heart is not "insurance" the heart, and everything is not going well. There are two things that cannot be ignored.
. Adhere to the scientific medication
Patients who install cardiac stent still need long-term drug treatment. is currently a common thing. It is to continue taking aspirin, clopidogrel , statin and other drugs under the guidance of a doctor, but this cannot achieve satisfactory recovery of the heart's microvascular blood supply.
In this case, suitable Chinese medicine is added for combined treatment, which can synergize and improve the treatment effect. , for example, is a "heart triple" scheme composed of Tongxinluo capsule , load statin and nicodil . Tongxinluo Capsules have triple effects on blood protection, microvascular protection, and ischemic tissue protection. They are used in combination with two other Western medicines. They can protect micro blood vessels and regulate blood lipids, anti-inflammatory , anticoagulation, prevent the formation of atherosclerotic plaques at the stent and other parts of the body and rupture of plaques, and reduce the recurrence of coronary stenosis and blockage, and reduce the recurrence of myocardial infarction.
2. Lifestyle management
After stent surgery, patients should also pay attention to low-salt and low-fat diet , quit smoking, limit alcohol, control weight, keep stools unobstructed, and avoid fatigue, infection and emotional excitement.
In addition, regular review of should be done after the operation. Re-stenosis is prone to occur one year after the operation. Regular review can detect problems early and treat them symptomatically and adjust medication, so as to achieve the best treatment effect and reduce the possibility of recurrence.
