1. Nitrate drugs: The more common drug is nitroglycerin tablets. Nitrates have clear anti-myocardial ischemia effects. They can reduce cardiac load by dilating arteries and veins and coronary arteries, increase coronary blood flow, and alleviate the symptoms of myocardial ischemia in patients, but complications such as hypotension must be avoided;

2. β-receptor blockers: can improve the symptoms of myocardial ischemia and inhibit the enhancement of myocardial contractility and the acceleration of heart rate. Improve the balance between myocardial oxygen supply and demand, improve myocardial metabolism, etc. Common ones include metoprolol, atenolol, etc. However, be careful not to use it in patients with severe bradycardia, atrioventricular block and other diseases;

3. Calcium antagonists: Patients with myocardial ischemia can also choose calcium antagonist drugs, such as nifedipine, Diltiazem, etc., can lower blood pressure, improve myocardial blood supply, inhibit myocardial contraction, etc.

In addition, because the occurrence of myocardial ischemia is related to coronary heart disease, hyperlipidemia, thrombosis and other conditions, patients with related conditions often need to take additional anti-lipidemic drugs, antiplatelet drugs, and thrombolytic drugs. Medications, anticoagulants. Therefore, the degree of illness and clinical symptoms vary between patients. When using drug treatment, specific analysis should be carried out according to the specific situation, and a suitable treatment plan should be selected according to the doctor's advice. If the patient's condition is more severe, drug treatment may not be effective. Other treatments, such as interventional therapy or surgical coronary artery bypass grafting, may be chosen to prolong the patient's survival.
