One year after the heart bypass surgery, generally need to review the electrocardiogram, cardiac ultrasound as well as laboratory tests of blood lipids, blood sugar, liver function, coronary angiography and other items. Because patients after cardiac bypass surgery have to be treated with double antiplatelet aggregation therapy for at least one year, to observe whether the drugs cause thrombocytopenia, liver function damage, and to strictly control the blood lipids and blood glucose after the surgery, so the review after cardiac bypass surgery is usually through the blood sampling to test the control of blood lipids, blood glucose and the recovery of liver function. Review of electrocardiogram and cardiac ultrasound are also needed to help determine the heart, size, shape, valve condition and recovery of heart function. If you still have intermittent chest pain, chest tightness, panic, shortness of breath and other uncomfortable symptoms one year after heart bypass surgery, it is recommended to review coronary angiography to clarify the status of blood vessels. After heart bypass surgery, we must follow the doctor’s instructions for regular review, and if discomfort occurs, we should consult the doctor in time and take active treatment under the guidance of a professional physician.
