Post-procedure precautions after cardiac angiography

After undergoing cardiac angiography, patients should remain in a strictly supine position and monitor the puncture site for bleeding or swelling, while also paying attention to wound care. Additionally, patients should drink plenty of water to increase urine output and promote the renal elimination of the contrast agent. Moreover, if patients experience any abnormal symptoms such as shortness of breath, difficulty breathing, or chest pain, they must promptly inform their doctor for appropriate management.
