Most physicians advise their patients to undergo the angiogram procedure (also known as angiography and arteriogram) when certain symptoms such as a heart attack or chest pain become a source of worry. A stress test is performed on patients who report chest pain, which is then followed by an angiogram test.
Angiography procedure aims at testing the blockages in the coronary arteries apart from any other cardiovascular-related ailments. Angiography and angiogram procedure can both locate narrowing arteries or blockages that may exist in different parts of the body.
Angiography is recommended for patients with coronary heart diseases (CHD), which can cause the heartbeat to stop suddenly and abruptly. The patient may also suffer from severe chest pain. Angiography can also be performed on patients on an emergency basis when they experience a heart attack. If the blockage is not treated immediately, then healthy tissues around the heart start perishing and turn into scar tissue. It can give rise to several long-lasting problems. Angiography may also be required in the case of a patient with aortic stenosis or those who have had an abnormal heart stress test.
Ionizing radiation exposure can be harmful to pregnant women and hence they are advised not to undergo an angiogram test. Damage to the fetus is one of the angiogram risks and therefore, pregnant women are advised against it. Patients who are scheduled to undergo angiogram procedure are asked to avoid eating and drinking 8 hours prior to it. Patients are asked to remove their jewellery and other accessories. Shaving is required in the armpit and groin area before an arterial puncture. An informed consent form detailing the possible complications is signed before the procedure.
The procedure involves administering a sedative for relaxation. An intravenous line is inserted into the vein. This is just a precautionary step to ensure that medication can be provided or blood products can be given in case of unwanted complications that take place during the angiography procedure.
The patient is kept under close observation for at least 6 to 12 hours if the procedure is performed on an outpatient basis. In case of a femoral artery puncture, the leg is almost kept immobile during the observation period.
Blood pressure and other vital signs are continuously monitored. A cold pack is applied to reduce swelling in the area of puncture and medications are given in case of extreme discomfort.
Hematoma may develop in a few patients. This indicates continuous bleeding from the puncture site and has to be watched for. Two to three days of complete rest is advised and driving should be avoided in the case of patients who have had fluorescein angiography. Direct exposure to sunlight should be avoided for at least 12 hours.
