Coronary vessels: the purpose and indications for
Coronary angiography - X-ray examination is the vessels of the heart, which is carried out to identify the location and extent of damage.
When carrying out diagnostics for clear radiographs vessels enter special contrast.
Assign heart coronary angiography for the diagnosis of suspected coronary heart disease, chest pain, heart attack, heart failure, angina, ischemic pulmonary edema, ventricular arrhythmias, cardiopulmonary resuscitation before surgery for heart defects.
Before doing coronary angiography patient compulsorily appoint donate blood for general analysis, the establishment of its group, excluding HIV, hepatitis B, C, and undergo an electrocardiogram echocardiogram. In addition, a cardiologist collects history reveals comorbidities and their symptoms. If necessary, the patient before the study recommended more research to pass, prescribe a course of drugs, allergy drugs, analgesics.
Immediately prior to coronary angiography is performed local anesthesia of the heart, and then through an artery in the thigh into the coronary artery catheter and allowed thereon contrast that spreads through the vessels and they become visible in angiography - special equipment that allows for large-format high-speed shooting and subsequent computer processing of the results. Determine the size of vascular lesions, the patient is diagnosed and prescribed treatment.
During the coronary vessels of the patient is observed anesthetist doctor kardioreanimatolog that, if necessary, be able to provide emergency aid to the patient. The risk of complications during coronary heart is minimal, but still there are cases when during the procedure revealed bleeding in the puncture, disturbed heart rhythm, coronary artery thrombosis, stroke, allergy to contrast (itching, swelling, rash, trouble breathing, decrease in pressure, anaphylactic shock).
In some cases, the doctor after consultation with the patient decides to do coronary angiography at the same time carrying out medical procedures: balloon dilatation and stenting.
Rebounding patients after coronary heart only one or two days, as low-traumatic procedure.
Contraindications to angiography
Make coronary angiography without consent can not, the procedure is considered minor surgery. Serious contraindications have no coronary angiography, but it is not recommended for patients with high fever, anemia, prolonged bleeding, including history, disorders of blood clotting, low potassium level.
With care prescribe coronary angiography of blood vessels in elderly patients, with significant variations in weight, untreated kidney failure, diabetes, a serious lung disease.
Contraindication for coronary angiography is the presence of allergy to contrast dye, so before the operation, it is desirable to pass allergy test used to dye.
In addition, it should be noted that the side effect of the contrast in the coronary angiography can not only allergies, but also renal failure, which must take into account when examining patients with heart failure, chronic renal failure, severe diabetes. This group of patients is recommended to prepare for the procedure in a hospital.
