What is coronary angiography of the heart?

Coronary angiography of the heart is an radiopaque method for diagnosing the state of the vascular bed. With the help of this method, the localization and degree of vasoconstriction are determined , as well as other arterial lesions (presence of thrombus, spasm, tearing, or presence of myocardial bridge). Today, this method of investigation is considered the most accurate and reliable in the detection of IHD. Coronary angiography of the heart allows choosing the optimal treatment tactics with the use of specific medications. In addition, this technique contributes to a more accurate assessment of the feasibility of bypass or stenting and angioplasty.

The procedure refers to invasive interventions. In other words, the coronary angiography of the heart is performed under operating conditions, with the introduction of a special catheter 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 manipulation.

Terms of intervention

Coronary angiography of the heart is carried out exclusively in the operating room. Usually, hospitalization is necessary for 2-3 days. On the first day, the samples are taken for analysis, allergic test for contrast agent is performed. The second day is the actual study. After the intervention, the patient should observe bed rest during the day . The pressure bandage is eliminated on the third day. The cardiosurgeon examines the patient, analyzes the results and prescribes therapy.

Indications

Diagnosis is assigned with a high risk of complications based on the survey data (with asymptomatic course of IHD including), with ineffective drug therapy for angina pectoris. Intervention is recommended in cases when non-invasive methods can not be applied. Indications include postinfarction, unstable (not amenable to drug treatment) angina pectoris. The study is scheduled for the forthcoming open-heart surgery in patients older than 35 years.

How is coronary angiography performed?

Based on the feedback of patients who underwent this procedure, it can be concluded that the intervention is of a low traumatic nature. The patient during the manipulations of the surgeon is conscious. The study is conducted under local anesthesia. At the initial stage, the specialist performs a puncture of the arteries (radial, axillary, femoral). In some cases, the insertion of the catheter is done through the vessel in the forearm. This shortens the observation period after diagnosis. A hollow tube of a small size is introduced into the artery, its diameter is 2 mm. A catheter is inserted through which a radiocontrast substance is poured. The blood flow is distributed through the coronary vessels. Under the control of an angiograph (a special device), a study is recorded. On average, the procedure lasts 10-20 minutes. According to patients, manipulation does not bring discomfort or discomfort. The recovery process takes a short time.

Coronary angiography of the heart: price

To date, the cost of intervention is about 20-25 thousand rubles.
