Coronary angiography is a radiopaque method for diagnosing the state of the vascular bed. Using this method, the localization and degree of narrowing of the vessels, as well as other lesions of the arteries (the presence of a thrombus, spasm, tear or the presence of a myocardial bridge) are determined. Today, this method of research is considered the most accurate and reliable in the detection of coronary heart disease. Coronary angiography of the heart allows you to choose the optimal tactics of treatment using specific medications. In addition, this technique contributes to a more accurate assessment of the feasibility of shunting or stenting and angioplasty.
The procedure refers to invasive methods of intervention. In other words, coronary angiography of the heart is performed under operating conditions, while a special catheter is inserted into the patient’s body. This procedure is carried out both for the purpose of diagnosis and for monitoring the state of blood vessels after surgical interventions. There are no absolute contraindications to the manipulation.
Intervention Conditions
Coronary angiography is performed exclusively in the operating room. Hospitalization for 2-3 days is usually necessary. On the first day, a sampling of tests is performed, an allergy test for a contrast agent is carried out. On the second day, the actual research is performed. After the intervention, the patient should observe bed rest during the day . The pressure dressing is removed on the third day. A heart surgeon examines the patient, analyzes the results and prescribes therapy.
Indications
Diagnosis is prescribed at a high risk of complications on the basis of examination data (with an asymptomatic course of coronary heart disease, including), with the ineffectiveness of drug therapy for angina pectoris. Recommended intervention in cases where non-invasive methods are not possible to apply. Indications include post-infarction, unstable (not amenable to drug treatment) angina pectoris. A study is scheduled for the upcoming open heart surgery in patients older than 35 years.
How is coronary angiography performed: reviews
Based on the reviews of patients who underwent this procedure, it can be concluded that the intervention is less traumatic in nature. The patient during the manipulation of the surgeon is conscious. The study is conducted under local anesthesia. At the initial stage, the specialist performs puncture of the arteries (radiation, axillary, femoral). In some cases, a catheter is inserted through a vessel in the forearm. This shortens the follow-up period after diagnosis.
A small hollow tube is inserted into the artery, its diameter is 2 mm. A catheter is inserted through it, into which a
radiopaque substance is poured
. By the flow of blood, the fluid is distributed through the coronary vessels. Under the control of an angiograph (special device), a study is recorded. On average, the procedure lasts 10-20 minutes. According to patients, manipulations do not cause discomfort or discomfort. The recovery process takes a short time.
Coronary angiography: price
Today, the cost of intervention is about 20-25 thousand rubles.
