Best treatment for myocardial infarction

Myocardial infarction is a heart disease that seriously threatens the life and health of patients. It refers to blood vessel blockage caused by coronary artery sclerosis, which often causes myocardial necrosis. As a patient, you should strengthen prevention in daily life and adopt timely first aid methods to treat the disease once you are ill. Let us learn about this aspect below.

Best treatment for myocardial infarction

"Time is myocardium, time is life." This is a classic quote widely circulated in the rescue of acute myocardial infarction. This sentence tells us very vividly that if we restore blood flow to the infarcted myocardial area as soon as possible, we can save more myocardium and thus reduce the mortality rate.

Currently, there are two main methods to restore blood flow in occluded coronary arteries: one is thrombolytic therapy, and the other is interventional therapy. There are many limitations to thrombolytic therapy: in patients with acute myocardial infarction. Only 1/3 are suitable for thrombolytic therapy; those who receive thrombolytic therapy. The vascular patency rate is only 50% to 70%. After thrombolytic therapy, approximately 1/3 of patients will experience recurrent myocardial ischemia due to the presence of residual stenosis.

Emergency interventional treatment for acute myocardial infarction is to install a tiny mesh alloy tube on a catheter with a compression balloon. When the catheter enters the diseased blood vessel, the balloon expands the stent to make it close to the blood vessel wall. The balloon is then deflated, the catheter is withdrawn, and the stent is permanently placed in place. The blood vessels can be expanded and the blood flow can be kept unobstructed, thus saving the myocardium that is on the verge of necrosis.

This treatment method has the advantages of less trauma, good efficacy, fewer complications and low mortality rate, but emergency interventional treatment requires the technical level and experience of the surgeon. The requirements for instruments and equipment, as well as collaboration among medical teams, are very high. It is also required that interventional treatment should be started within 60-90 minutes after the patient sees the doctor. Therefore, this operation can currently only be performed in some large cardiac intervention centers in China. It must be emphasized that the treatment effect of acute myocardial infarction is closely related to time. The earlier the time, the better the treatment effect.

Is it okay to put the stent in?

Many patients with coronary heart disease have a wrong idea that everything will be fine after a stent is placed. They do not take medicine according to the doctor's advice and do not pay attention to changing their lifestyle. As a result, occlusion of the stent may occur or lesions may develop in other parts of the blood vessels.

Currently, there is increasing evidence suggesting that for patients with acute myocardial infarction, interventional therapy with stent implantation can open the narrowed blood vessels, restore blood flow in the blood vessels, and significantly reduce mortality. However, stents only relieve stenosis and do not target coronary heart disease itself.
