Risks associated with coronary angiography

RiskDescription
Bleeding and hematomaThe insertion site may bleed or develop a hematoma.
InfectionInfection can occur at the catheter insertion site, although rare.
Allergic reactionsPatients may experience allergic reactions to the contrast dye.
ArrhythmiasThe procedure can sometimes trigger abnormal heart rhythms.
Contrast-induced nephropathyThe contrast dye can cause kidney damage, particularly in patients with existing kidney conditions.
Radiation exposureRepeated exposure to X-ray radiation may increase the risk of cancer.
Vascular complicationsInjury to the artery used for catheter insertion can occur, which may lead to pseudoaneurysm or arteriovenous fistula.
Heart attack or strokeThe procedure can dislodge plaque, potentially leading to a heart attack or stroke, although this is rare.
DeathIn very rare cases, serious complications from coronary angiography can be fatal.
