Exploration of Cardiology

Risk	Description
Bleeding and hematoma	The insertion site may bleed or develop a hematoma.
Infection	Infection can occur at the catheter insertion site, although rare.
Allergic reactions	Patients may experience allergic reactions to the contrast dye.
Arrhythmias	The procedure can sometimes trigger abnormal heart rhythms.
Contrast-induced nephropathy	The contrast dye can cause kidney damage, particularly in patients with existing kidney conditions.
Radiation exposure	Repeated exposure to X-ray radiation may increase the risk of cancer.
Vascular complications	Injury to the artery used for catheter insertion can occur, which may lead to pseudoaneurysm or arteriovenous fistula.
Heart attack or stroke	The procedure can dislodge plaque, potentially leading to a heart attack or stroke, although this is rare.
Death	In very rare cases, serious complications from coronary angiography can be fatal.
