I heard from the key points of knowledge listed by Student Pan, and other students nodded frequently.

Yue Wentong did not deny: "The patient is taking warfarin."

As a patient after PCI surgery, following the doctor's advice, he must take warfarin anticoagulants for a long time, with the purpose of preventing thrombosis in the stent. Intrastent thrombosis is more fatal than restenosis in the stent. Acute myocardial infarction caused by the thrombosis segment will cause the mortality rate to reach 20 to 40%.

It is not enough to use anticoagulants alone. Doctors often prescribe doctors to patients to take aspirin as antiplatelet therapy. Aspirin is the most widely used antiplatelet drug in clinical practice and is an inhibitor of thromboin A2                                                                                                                                                                                                                               �

When laymen may find it strange when they hear it, is monoclonal anticoagulants not good? Why do you need to add antiplatelet drugs? Are they all the same antithrombotics? There are three types of antithrombotic drugs. In addition to the above two, the other one is the most direct, called thrombolytic drugs. In fact, thrombolytic drugs are a common treatment plan for clinical rescue of patients with acute myocardial infarction when there is no drug stent in the early stage and no medical insurance reimbursement with naked stents, it is a common treatment plan for patients with acute myocardial infarction in clinical practice. thrombolytic drugs are as expensive, but they are cheaper than stent surgery and bypass surgery. Think about its technical key points, you know where the cheaper is. There is no need to perform surgery. The technical requirements for hospitals and doctors are low. Small and medium-sized hospitals can carry out the former. The former must be carried out in large hospitals.

The people are poor and have no choice.

Doctors in major hospitals do not like this because the use of thrombolytic drugs must be based on timing. It is best to use them within three hours of myocardial infarction, otherwise the effect will be greatly reduced and ineffective. Secondly, thrombolytic drugs are ineffective against stubborn thrombosis, which means that even if thrombolytics are done, an angiography must be performed and then stents must be put on. Moreover, the drugs affect the whole body, unlike surgery limited to local body parts, and complications caused by thrombolytic treatment will be terrible. Many patients with underlying diseases must use them with caution, and elderly people with high age and various problems throughout the body are contraindications. There are many myocardial infarctions in the elderly.

For patients who are a little money, the doctor persuaded them to immediately pk the thrombolytic treatment and thrombolytic drugs. After the operation, use two other antithrombotic drugs combined to make the effect better.

Although anticoagulants and antiplatelet drugs are both antithrombotic drugs, they seem to be similar to thrombolysis, but they are really two types of drugs with completely different mechanisms of action. Whether it is physiological hemostasis or abnormal thrombosis, they are actually two processes of platelet aggregation and coagulation. The protagonist of the former is platelets, and the platelets run to a piece adhered to the wall of the blood vessel to stop bleeding or form a thrombus. The important role of the latter is the coagulation factor, which is activated from a quiet state when the blood vessel is damaged, prompting the fibrin to change from soluble to insoluble, and blood cells are pulled into blood clots.

According to this principle, the researched antiplatelet drugs should drive away the platelets and not release aggregated adhesions. Anticoagulants should prevent the coagulation factor from being activated or converted.

What Xie Wanying knew before and after her rebirth was that she wanted patients to truly antithrombosis after PCI, using warfarin and aspirin was not effective enough. What she needed was anticoagulant plus dual antiplatelet therapy, which was abbreviated as DAPT in English.
