At present, there is no special medicine for insufficient blood supply to the heart. Medicines for insufficient blood supply to the heart generally include nitroglycerin drugs, antiplatelet drugs, anticoagulant drugs and so on, and you need to choose the appropriate medication under the guidance of your doctor. 1. Nitroglycerin drugs: such as nitroglycerin tablets, isosorbide nitrate tablets, etc., can reduce myocardial oxygen consumption and improve myocardial perfusion, thus alleviating the discomfort symptoms. 2. Antiplatelet drugs: can inhibit platelet coagulation, avoiding blood vessel blockage and preventing the occurrence of insufficient blood supply to the heart. Commonly used drugs include clopidogrel bisulfate tablets and aspirin. 3. Anticoagulant drugs: such as warfarin sodium tablets, rivaroxaban tablets, etc., can prevent the formation of blood clots in blood vessels, so that the heart can supply blood normally. In case of insufficient blood supply to the heart, you should go to the hospital in time for examination and treatment of the cause.
