Can myocardial ischemia do bypass

summary

Many heart diseases can cause myocardial ischemia, so myocardial ischemia is also a common disease. Some patients want to know if they can do bypass surgery when they have myocardial ischemia. Generally speaking, they should see according to the doctor's advice. Now let's talk about whether myocardial ischemia can be used as bypass.

Can myocardial ischemia do bypass

First: myocardial ischemia is an important cause of coronary heart disease, in clinical practice, coronary artery stenosis is the better main cause of myocardial ischemia, most patients with myocardial ischemia also have the change of coronary artery stenosis. Clinical coronary angiography showed that although many patients did not have coronary stenosis, they still had myocardial ischemia. Therefore, the bypass operation for myocardial ischemia should be very careful.

Second: coronary artery bypass grafting is to take a segment of autologous great saphenous vein or other blood vessels located in the leg to bypass between the aorta and the distal end of the coronary artery occlusion lesion, so that the blood of the aorta can be supplied to the distal end of the coronary artery through the transplanted blood vessels, so as to restore the blood supply of the corresponding myocardium, improve the myocardial ischemia state, and relieve the symptoms of angina pectoris. To put it simply, it is to establish a channel between the proximal and distal parts of coronary artery stenosis. It usually takes only 6-7 minutes for doctors to build a "bridge". This technique has the advantages of small trauma and quick recovery.

Third: in patients with myocardial ischemia, if angiography finds that a coronary artery is occluded but the myocardium is not necrotic, it means that this part of the myocardium has good collateral circulation. Theoretically speaking, it is equivalent to more than 90% stenosis of this artery. If the myocardial oxygen demand is increased, such as exercise, angina pectoris or myocardial infarction may be induced. If conditions permit, stent implantation or bypass surgery can be performed, If the blood vessel can not be opened, then consider the bypass.

matters needing attention

In general, it is not recommended to perform bypass surgery directly, although the current science and technology have made enough progress. All kinds of medical equipment are also guaranteed, but for bypass surgery, patients also need to have strong physical fitness, and they must follow the doctor's advice.
