Coronary angiography is a diagnostic procedure performed to assess blood flow within the coronary arteries, as well as to evaluate blood flow and pressure in the cardiac atria and ventricles. It is also used to examine the function of the heart valves and to diagnose various abnormalities related to the contraction of the heart walls.
The examination is performed in the presence of any of the following conditions:
- Reduced blood flow to one or more regions of the heart
- Severe angina symptoms, such as chest pain occurring with minimal physical exertion
- A history of myocardial infarction (heart attack)
- Medical conditions that prevent other diagnostic tests from being performed, or when other tests fail to provide sufficient diagnostic information
- Evaluation of the degree of narrowing or disease affecting the aorta
- Preoperative assessment prior to cardiac surgery to evaluate overall cardiac function
Pre-Procedure Instructions
- Refraining from eating or drinking for at least six hours prior to the procedure
- Informing the physician of all medications currently being taken, with particular attention to blood-thinning medications, which may need to be discontinued
- Hospital admission one day prior to the procedure in cases of certain medical conditions, such as renal failure
Potential Risks of Coronary Angiography
- Chest pain
- Shortness of breath
- Dizziness
- Risk of infection
- Coronary angiography is not performed during pregnancy unless it is absolutely necessary.
- If the angiography results are normal, no narrowing of the coronary arteries supplying the heart is expected, nor should any other abnormalities be detected. If the results are abnormal, the physician may identify narrowing or blockage within the coronary arteries.
- Avoid pushing or pulling heavy objects for 5 to 7 days, Refrain from physical activity for 2 to 5 days following the procedure
- Avoid swimming during the first week, Showering is permitted; however, ensure that the catheter insertion site remains dry for the first 24 to 48 hours
- Avoid driving after the procedure due to the lingering effects of anesthesia
