More than one year after stenting, fatigue occurs after basic examination and then coronary angiography, and if necessary, stenting can be performed again. Occasional postoperative fatigue may be related to overexertion, which can be relieved after rest. It is recommended to avoid strenuous activities and ensure balanced nutrition. However, if you often feel tired, accompanied by symptoms such as chest tightness and panic, you need to be alert to the possibility of re-infarction. Electrocardiogram is needed first, if it suggests myocardial infarction, it is recommended to undergo coronary angiography to observe whether there is any thrombus or stenosis in the blood vessel. If the stenosis is serious after the operation, another operation should be considered. It should be noted that hypothyroidism can also cause weakness, and it is recommended to take 5 tests of thyroid function to know the levels of thyroxine and thyrotropin, and hormone replacement therapy should be carried out if there is hypothyroidism. After stenting, antiplatelet drugs such as aspirin and clopidogrel, as well as statins such as simvastatin and resuvastatin, should be taken to prevent thrombosis by following the doctor’s instructions correctly.
