To support your recovery process after an angiogram, the following important points should be noted: Make sure to consume plenty of water and other non-alcoholic fluids as recommended by your doctor. Absolutely avoid smoking and alcohol consumption. Refrain from taking a shower within the first 24 hours. In case you experience any unexpected changes or discomfort in your body, it is crucial to contact the cardiologist who performed the procedure immediately. Diligently follow your doctor's information and instructions regarding post-angiogram care and potential risks.
