The full name of stenting is coronary stenting. Trimetazidine can be stopped one year after the procedure if you are stable on a class of medications and have no symptoms of intolerance. Coronary stenting is a procedure in which a metal stent is permanently placed into the diseased area of a coronary artery and keeps the coronary artery lumen open. Trimetazidine relieves angina by protecting cellular energy metabolism and stabilizing the intracellular environment during hypoxia or ischemia. Trimetazidine can be used as a second-line and adjunctive treatment for angina pectoris when first-line antianginal therapy is ineffective or intolerable. However, Trimetazidine may cause allergy, Parkinson’s syndrome, cardiac arrhythmia, renal impairment and other adverse reactions, so it is contraindicated in patients with allergy to the drug, Parkinson’s syndrome and severe renal insufficiency. One year after coronary stent implantation, trimetazidine can be discontinued if the condition of taking aspirin, clopidogrel, isosorbide mononitrate, and Rosuvastatin is stable and there are no symptoms of intolerance. It is not recommended to stop trimetazidine by yourself, it is recommended to go to the hospital to check the electrocardiogram, cardiac ultrasound and other items before stopping the drug under the guidance of the doctor.
