各位朋友，大家好，现在是“每天健康三分钟”时间，我是道简-心血管康复医生集团、河南中汇心血管医院护士李佳念，今天我们来共同学习下心脏支架的一些小知识。

众所周知，做心脏支架手术可改善冠状动脉狭窄、心肌缺血的问题，还可以告别终身服药的苦恼，当出现急性心梗、不稳定性心绞痛等疾病时，都可以通过植入心脏支架缓解病情，甚至挽救生命。但是有些患者对于心脏支架的好处和坏处不太清楚，所以在选择这种手术时，内心非常的忐忑，那么，做心脏支架的利与弊具体有哪些呢？

一、做心脏支架的好处

1.改善冠状动脉狭窄

一般动脉堵塞75%以上后，医生会建议患者进行心脏支架植入治疗，用支架撑到狭窄的动脉处，防止动脉再次回缩，这样就可以有效的改善动脉狭窄的问题。

2.改善心肌供血

一般出现心梗时，患者会因为血液循环不畅通，出现心绞痛、胸痛等症状，选择心脏支架介入治疗后，动脉狭窄的情况得到改善，血液流通变得畅快，就可以很好的改善心肌供血问题。

3.告别终身服药

目前心脏支架的植入手术中，有金属心脏支架和可溶性心脏支架两类，一般植入金属心脏支架时，还需要终生服药；如果应用可溶性心脏支架，就可以告别终身服药的苦恼。

二、做心脏支架的弊端

1.有出血症状

虽然现在心脏支架手术已经比较成熟，做这种手术是比较安全的，但是做了心脏支架手术后还需要服用药物抗溶，有些患者在长期应用抗血小板的药物后，会出现出血的情况。

2.出现支架内血栓

做的心脏支架手术一年之内很容易在支架内再次出现血栓，这对患者的身体健康也会造成一定的影响。

3.血管再次狭窄

因为在进行心脏支架介入治疗时，大多数应用的是金属支架，这对于心血管来说是一种异物植入，所以病变的血管会出现保护性反应，有更多的细胞包绕支架，就可能导致血管再次出现狭窄。

4.过度医疗

虽然心脏支架手术是一种介入治疗，创伤比较小，恢复快，可以减少心绞痛发作的频率。但是最好是血管狭窄达到75%以上后再采取这种方法进行治疗，目前许多患者狭窄程度不足75%，甚至不足50%，这就造成了过度医疗。

最后祝大家生活愉快，身体健康！想了解更多冠心病科普小知识，请关注我们，咱们下期见。

Advantages and disadvantages of heart stent

Dear friends, nice to meet you!Now it is time for “health talk for three minutes every day”,My name is Li Jianian, a nurse of Daojian Doctor Group of Cardiovascular Rehabilitation and Henan Zhonghui Cardiovascular Hospital.Today we're going to learn something about cardiac stents.

As we all know, cardiac stent surgery can improve the problems of coronary artery stenosis and myocardial ischemia, and also can bid farewell to the pain of lifelong medication. When there are acute myocardial infarction, unstable angina and other diseases, cardiac stent can be implanted to alleviate the disease, or even save lives.But some patients are not clear about the advantages and disadvantages of cardiac stent, so they may be very nervous when choosing the operation method.So, what are the advantages and disadvantages of cardiac stent?

1、 Benefits of heart stenting

1. Improve coronary artery stenosi

Generally, when the artery is blocked by more than 75%,the doctor will recommend the patient to carry out cardiac stent implantation treatment, support the stenotic artery with stent, prevent the artery from retracting again, so as to effectively improve the problem of artery stenosis.

2. Improve myocardial blood supply

In general, patients with myocardial infarction will have angina pectoris, chest pain and other symptoms due to poor blood circulation. After cardiac stent intervention, the situation of arterial stenosis will be improved, and the blood flow will become smooth, which can improve the myocardial blood supply.

3. Farewell to lifelong medication

At present, there are two kinds of heart stent implantation: metal stent and soluble stent.Generally, when metal stent is implanted, life-long medication is needed.If soluble stent is used, life-long medication can be avoided.

2、 Disadvantages of heart stenting

1. Bleeding

Although the cardiac stent surgery is relatively mature now, it is relatively safe to do this kind of surgery, but after the cardiac stent surgery, we still need to take anti platelet aggregation drugs. Some patients will have bleeding after long-term application of anti platelet drugs.

2. Stent thrombosis

It's easy to have thrombosis again in stent implantation within one year after cardiac stent surgery, which will also have a certain impact on the health of patients.

3. Restenosis

Because in the interventional treatment of cardiac stents, most of them are metal stents, which is a kind of foreign body for the human body, so the diseased blood vessels will have a protective reaction, and more cells will wrap around the stents, which may lead to restenosis of blood vessels.

4. Over treatment

Although cardiac stenting is a kind of interventional therapy, it has the advantages of less trauma, faster recovery, and can reduce the frequency of angina pectoris. But it is best to take this method after the vascular stenosis reaches more than 75%. At present, the degree of stenosis of many patients is less than 75%, or even less than 50%, which leads to excessive medical treatment.

Finally, I wish you all a happy life and good health!To learn more about Coronary heart disease, please pay attention to us. See you next time.
