Coronary angiography is generally harmless under the supervision of a regular physician, and some may occur such as allergies or coronary artery damage.
Coronary angiography is an invasive test that requires a puncture through the radial or femoral arteries to deliver the angiography catheter into the blood vessels of the heart. Since anesthesia is required during the test, allergy to anesthetics is likely to occur.
In addition, the use of contrast medium, which is an iodine-based preparation, is also likely to cause allergic reactions in allergic individuals, ranging from mild allergic reactions such as skin rashes to severe allergic reactions such as laryngeal edema and anaphylactic shock.
In addition, if the coronary angiography catheter is not properly operated, it is likely to damage the coronary artery openings, leading to tearing of the coronary artery clips and the formation of acute thrombus leading to acute myocardial infarction.
In addition, puncture complications, such as arteriovenous fistula or pseudoaneurysm, may occur when performing an arterial puncture.
Coronary angiography should be performed by a medical professional, and any discomfort should be treated aggressively.
