Widespread myocardial ischemia often suggests that ischemia exists in multiple walls of the heart, and can be relieved by improving ischemia, antithrombotic therapy, and revascularization. 1. Improvement of ischemia: After myocardial ischemia, nitrate drugs such as isosorbide dinitrate can be taken to dilate blood vessels and reduce myocardial oxygen consumption so as to improve the symptoms. 2. Antithrombotic therapy: myocardial ischemia may be caused by thrombus blockage of coronary arteries, antiplatelet drugs such as aspirin have the effect of antiplatelet to prevent thrombosis and myocardial ischemia. 3. Revascularization: Revascularization therapy can also improve the symptoms of myocardial ischemia, and the commonly used revascularization surgeries include percutaneous coronary intervention and coronary artery bypass grafting. Widespread myocardial ischemia needs to be treated promptly and actively with the doctor, and should strictly follow the doctor’s arrangement to take medication or undergo surgery. In order to avoid further aggravation of the condition, so that the body is subjected to greater harm.
