Myocardial ischemia can take aspirin. If the myocardial ischemia is mild, usually without clinical manifestations, but mild stenosis of the coronary vessels is found during the electrocardiogram or coronary artery CT, the patient can usually take oral aspirin for secondary prevention. In severe cases, such as those with coronary stenosis greater than 50% or even more, oral aspirin is necessary for conservative treatment or after interventional therapy, and some patients may also take oral aspirin along with oral clopidogrel, dual antiplatelet therapy, plus plaque stabilizing drugs, such as atorvastatin oral antioxidant. When taking oral aspirin, patients should pay attention to whether they have a history of gastric ulcers or gastric bleeding. If there is pain in the stomach or bleeding spots on the body, they should seek medical attention.
