The coronary angiography is not advised for the accompanying:
● Acute renal failure ● Chronic renal failure and diabetes ● Gastrointestinal bleeding ● Fever, as it can be a sign of infection ● Active infection within the body ● Local infection at the incision site ● Severe anemia ● Acute stroke ● Severe hypertension
Duration Of Operation
30 to 60 minutes
The coronary angiography is generally carried out once other non-invasive tests, such as a stress test, echocardiogram or electrocardiogram have been done.
Eating or drinking anything at least 10 hours prior to the coronary angiography is restricted.Some medicinesmay be prescribed for the patient throughoutthis time.
How It Is Performed
Patients will be asked to lie on an X-ray table before being given a sedative and a local anesthetic. A catheter should be placed into the patient’s blood vessels. Specialists can utilize the groin area or the arm for this aim. The incision placeis shaved, washed, and disinfected. Next, the catheter is introduced into the blood vessel, and it is cautiously oriented to the coronary arteries or the heart. A radio-opaque dye is entered over the catheter. The specialists now can find out any anomalies in the heart or coronary arteries of the patient. If some arteries are excessively narrow, angioplasty might be carried out, or a stent might be put. The procedure lasts about an hour. When the coronary angiography is done, the specialist closes the incision and applies a small bandage.
Patients are asked to lie flat in their beds for about 8 hours after the procedure. They may not move their arms or legs, relying on the place where the catheter was presented. Light pressure might be put on the incision place so as to restrain any bleeding.
Patients should stay away from heavy physical activities for a couple of days after the coronary angiography. They may come back to their normal activities and work, relying upon their test outcomes.
Possible risks and complications of coronary angiography can consist of:
Coronary angiography accompanying side effects might be:
● Slight bruising nearthe incision place ● Mild pain and discomfort ● Slight swelling
According to a survey from 7.412 patients who underwent coronary angiography procedures between 1990 and 2000, the complication rate found at 0.8%, and the overall mortality rate for this procedure was 0%.
Before And After
