The primary goal in the treatment of myocardial infarction is to open the infarcted vessel and restore myocardial perfusion as soon as possible. The first choice is coronary intervention, followed by thrombolytic therapy. In general, there is at least one hospital in the city that can perform 24-hour coronary intervention, so you should go to the hospital that has the ability to do emergency coronary intervention as soon as possible; however, some counties and towns do not have hospitals to carry out coronary intervention, and the travel time to the intervention hospital is more than 90 minutes, so do not delay the opening time of the blood vessel, you can go to the county hospital for thrombolysis first, and then transfer to the hospital that has the ability to do coronary intervention The hospital that has the ability to do coronary intervention. Acute heart attack is caused by the rupture of coronary plaque and the formation of thrombus, resulting in acute occlusion of coronary arteries, which leads to myocardial necrosis. Early recanalization of the acutely occluded coronary artery and restoration of myocardial perfusion can save the ischemic myocardium and reduce the infarcted area. 1.Percutaneous coronary intervention Emergency percutaneous coronary intervention is a treatment method to treat acute heart attack by using minimally invasive methods and applying interventional techniques to open the infarct-related arteries. Emergency percutaneous coronary intervention (PCI) is the first and main treatment method for acute heart attack. (1) Indications for intervention For patients with heart attack, direct coronary intervention is almost always considered the first choice; for those who are unsuccessfully recanalized by thrombolytic therapy, remedial coronary intervention should also be performed; or remedial coronary intervention should be performed 3-24 hours after thrombolysis. (2) Pre-intervention preparation Before the intervention, the doctor will talk with the family, explain the risks and sign the informed consent form. At this time, family members please make sure not to hesitate, time is the heart muscle, and the sooner the reperfusion treatment starts, the better. 2.Thrombolysis Thrombolysis is a treatment method to dissolve fresh thrombus in the infarct-related coronary artery by intravenous injection of thrombolytic drugs, so that the occluded artery can be reopened rapidly. Patients who have thrombolysis 3 hours after the onset of disease will benefit the most. (1) Indications for thrombolysis Thrombolysis is preferred when acute infarction occurs within 3 hours of onset and when emergency percutaneous coronary intervention is not available. Patients with infarction <12 hours of onset and no contraindications to thrombolysis can be treated with thrombolysis. Current guidelines recommend that the time from hospital admission to thrombolysis initiation be within 30 minutes in order to open the vessel as soon as possible. (2) Preparation before thrombolysis Before thrombolysis, the doctor will talk to the family, explain the risks and sign an informed consent form. Both the doctor and the patient should sign their names and time on the informed consent form, which should be accurate to the minute. At this point, the family must not hesitate, time is the heart muscle and the sooner the reperfusion treatment starts, the better.
