Myocardial ischemia is mostly caused by coronary artery disease and requires medications to relieve symptoms and improve prognosis, as well as to treat combined high-risk factors and slow down the progression of atherosclerosis. The following drugs are the most basic treatment options: 1. Symptom relieving drugs: mainly include beta-blockers, nitrates and calcium channel blockers. beta-blockers reduce heart rate and myocardial oxygen consumption, such as metoprolol, atenolol and bisoprolol; nitrates dilate blood vessels, relieve angina and prevent angina attacks, such as isosorbide 5-mononitrate, isosorbide mononitrate extended release Calcium channel blockers play a role in relieving angina by improving coronary blood flow and reducing myocardial oxygen consumption, such as amlodipine, felodipine, nifedipine, etc. 2, improve the prognosis of drugs: patients with myocardial ischemia need to prevent blood clots. Aspirin prevents thrombosis through the effect of anti-platelet aggregation, and should be taken by all patients without contraindications. Patients who cannot tolerate aspirin can be treated with clopidogrel as an alternative. Lipid-lowering drugs can play a role in lowering cholesterol, stabilizing plaque and preventing the progression of atherosclerotic plaque, such as atorvastatin and simvastatin. Angiotensin-converting enzyme drugs can play a role in protecting the heart, preventing and improving the prognosis of patients with coronary heart disease combined with heart failure, such as perindopril, etc.; beta-blockers can protect the heart, reduce cardiac oxygen consumption and improve the prognosis of patients with coronary heart disease, such as metoprolol and bisoprolol, etc. 3. Prevention of high-risk factors: Patients with combined hypertension, hyperglycemia and hyperlipidemia also need to control blood pressure, blood sugar and lipid at the same time to slow down the progress of atherosclerosis. The basic treatment of myocardial ischemia is to improve symptoms, improve prognosis and control risk factors, and the general scheme is similar, but what specific drugs should be taken best depends on the specific condition of the patient, while all the above drugs need to be taken under the guidance of a doctor, and patients should not judge the use of drugs on their own.
