One month after the cardiac stent surgery, the cardiac ultrasound results suggest normal, but the patient should continue to improve other tests. Because cardiac ultrasound can only reflect part of the problem, but not completely reflect the state of the heart, it is necessary to improve other related tests, such as electrocardiogram, cardiac enzyme profile, coagulation, fecal occult blood test and so on. One month after cardiac stent surgery, a review is needed to determine the status of the stent and the patient. The review includes physical examination, consultation and auxiliary examination. Consultation and physical examination can determine whether the condition is stable or not from the patient’s symptoms and signs, while the auxiliary examination, except for the cardiac ultrasound, also has special significance. After cardiac stenting, patients need to take oral anticoagulant drugs for a long period of time. At this time, perfect examination of coagulation and fecal occult blood test can help to judge the use of drugs and the bleeding risk of patients. Electrocardiogram, cardiac enzyme profile and other tests can reflect the current state of the heart. After a month after the stenting procedure, the patient needs to be re-examined in time, and the doctor will adjust the use of medication appropriately according to the patient’s condition.
