Is cardiac angiography harmful to the body?

Cardiac angiography is generally considered safe, but it may involve certain minor risks or discomfort. Cardiac angiography is a diagnostic procedure that involves injecting a contrast agent and using X-ray imaging to observe the condition of the heart's blood vessels. In most cases, this examination does not cause significant harm to the body, although some individuals may experience temporary side effects, such as mild allergic reactions to the contrast agent, nausea, or pain at the puncture site. In rare cases, serious complications such as kidney function impairment or vascular injury caused by the contrast agent may occur, but these are uncommon and can be effectively managed under the care of a professional medical team.

To ensure the procedure goes smoothly, it is recommended to inform your doctor about your health status in advance, especially whether you have any history of allergies, kidney dysfunction, or other medical conditions. Prior to the exam, you should follow your doctor's instructions regarding fasting or discontinuation of certain medications, and maintain a positive mental state to reduce anxiety. After the exam, pay attention to your body's response, particularly whether there is swelling or bleeding at the puncture site. If you experience any abnormal symptoms such as difficulty breathing, severe chest pain, or persistent fever, seek medical attention immediately. Maintaining regular sleep patterns and a healthy diet in daily life can help improve your body's tolerance, facilitate a successful examination, and reduce associated risks.
