How is a CT Scan of the Heart and Coronary Angiography with Contrast Performed?
Patients must arrive 30 minutes earlier for preparation to ensure a successful procedure.
Medical staff will monitor the heart rate (it should be below 65 bpm) and insert an intravenous (IV) catheter.
The examination is performed under cardiac monitoring, with electrodes attached for an electrocardiogram (ECG).
During the scan, the patient lies on the CT scanner table. The procedure is painless, but it is crucial to remain still. Several times during the scan, the patient will need to hold their breath for 10-15 seconds. The total procedure lasts about 20 minutes.
A contrast agent (approximately 100 ml) is injected into the vein, allowing visualization of the heart's blood vessels and chambers. A temporary warmth sensation or an unpleasant taste in the mouth may occur—this is normal and does not indicate any harmful reaction.
After the scan, patients must stay in the medical facility for 15-20 minutes to ensure everything is normal.
What to Bring and Prepare for the Examination:
Doctor’s referral from a general practitioner or specialist.
Blood test results, specifically kidney function indicators (UREA, CREATININE, GFR).
If allergic to iodine, inform the doctor in advance.
Patients with thyroid issues should consult an endocrinologist before the procedure.
Patients with kidney failure should consult a nephrologist to assess feasibility.
Do not eat for 4 hours before the scan.
Drinking is allowed, except for caffeinated beverages (coffee, cola, etc.).
For a successful and high-quality examination, the referring doctor must properly prepare the patient. If necessary, medications will be administered on-site.
