Coronary angiography is generally safe but carries some risks. Recovery is quick for most people, often within days.
Risks
Risks are rare but can happen. Doctors watch closely during the procedure.
-
Bleeding or bruising at the catheter site (groin or wrist) is common but mild.
-
Blood vessel damage may occur where the catheter enters.
-
Allergic reaction to the dye affects a few patients; mild rash or nausea.
-
Kidney issues from dye, especially in those with prior kidney problems.
-
Irregular heartbeat (arrhythmia) during or after.
-
Rare serious risks include heart attack, stroke, or infection.
Recovery Timeline
You go to a recovery area right after. Staff check vitals for hours.
Lie flat for 4-6 hours if groin site used. This stops bleeding. Wrist access lets you move sooner.
Care Instructions
Drink lots of fluids. This flushes dye from kidneys.
Avoid heavy lifting or strenuous activity for 2-7 days. Walk lightly to aid circulation.
The site may bruise or feel sore for days. Use ice for swelling.
When to Seek Help
Call a doctor if you notice these signs:
-
Worsening pain, swelling, or bleeding at site.
-
Fever or chills (infection sign).
-
Chest pain, shortness of breath.
-
Leg/arm numbness, color change, or coldness.
-
Trouble urinating or dark urine.
Most return to work in 1-2 days. Full recovery takes 1 week. Follow your doctor’s plan
