A one-year post cardiac stent review does not necessarily require an angiogram. Usually the gold standard for a patient’s review one year after cardiac stent implantation is a coronary angiogram, as the angiogram is generally the most accurate and can clearly see if the narrowed vessel is still open. Cardiac stents do not require an angiogram to be done after one year, and angiography is an invasive test that can cause serious damage, such as in some patients who have poor kidney function and are not recommended to have iodine injected into them, so an angiogram is not always needed. Review after one year of cardiac stenting general cardiac spiral CT, electrocardiogram and cardiac ultrasound can also be reviewed. In addition, patients can also have blood drawn to review lipids and blood glucose, and have their blood pressure measured regularly. If patients do not have symptoms of severe myocardial ischemia, imaging is not necessary. For the review after one year of cardiac stenting, patients are advised to choose the appropriate examination according to their own situation under the guidance of their doctors.
