The main risks of cardiovascular angiography are bleeding or edema at the puncture site, contrast nephropathy, and contrast allergy.
1. Bleeding or edema: cardiovascular angiography is an invasive test, during which arteries are punctured. The puncture process may lead to local bleeding, hematoma at the puncture point and damage to the inner wall of the vessel.
2. Contrast nephropathy: During cardiac imaging, a certain amount of contrast agent will be injected into the body, which requires the kidneys to metabolize out of the body, and if the patient suffers from renal insufficiency, it will cause contrast nephropathy.
3. In addition, during cardiac imaging, some patients may experience acute complications such as contrast allergy, angina pectoris, myocardial infarction and cardiovascular spasm.
There are certain risks associated with cardiac angiography, so when performing cardiac angiography, it is necessary to judge whether it is suitable to perform the examination under the guidance of a doctor, and pay attention to care after performing cardiac angiography.
