Coronary angiography: reviews of doctors, the general trend of applying the method for diagnosing cardiac pathologies
For the diagnosis of heart disease is usedseveral instrumental informative methods of research that allow to determine with a high degree of accuracy the presence of a morphological substrate of some organ pathologies. Among such methods, echo cardiography and coronary angiography are most often used. Testimonials of target specialists about them make it possible to isolate these methods as the main ways to establish the severity of pathology. At the same time, every doctor pursues the principle that confirmation of a diagnosis implemented instrumentally is the main task of a doctor, because based on the results of a specific study, adequate therapy or rehabilitation can be planned.
Coronary angiography is an invasive method of diagnosiswith high specificity and informativeness to the coronary arteries of the heart. It allows you to accurately detect the growth of atherosclerotic plaques, as well as assess the degree of occlusion of a particular vessel or its site, which will have prognostic value. Also, coronary angiography, reviews of doctors about which argue rationality of its use, allows you to clearly differentiate the morphology of a particular plaque or thrombus, to recognize the signs of their destruction, to find out the location relative to the walls of the vessel.
The technique of coronary angiography is quiteIt is simple and associated with a small amount of time spent. Initially, the place near the introduction of the introducer, the channel for the installation of the catheter, is cut off with a solution of a local anesthetic, to which a small fraction of adrenaline is added to reduce the resorption of the latter. A radiocontrast substance is fed through the catheter, filling the coronary arteries that extend from the aorta to the time of its arcing. It, spreading with arterial blood, falls into the smaller branches of the arterial vascular bed of the heart.
After the catheter is filled, images are taken,the results of which are processed by computer programs, after which the result is visualized. At the same time, in this form, coronary angiography, reviews of which by the medical staff favorably distinguish this method among other instrumental methods of heart examination, is the most optimal way of visualizing both the coronary arteries themselves and their branches carrying blood to the myocardium.
In this case, the processed result of coronary angiographyallows differentiating areas with contrast, which are X-ray positive tissue, that is, absorbing radiation. These properties are distinguished by blood, while the walls of the artery are not allocated, but have a dark edge. By its curvature, and also by the thickness of the strip of liquid colored by contrast, one can judge the width of the lumen of the arterial vessel in the controlled area. This information is important for the diagnosis of vascular pathologies, atherosclerosis, as well as planning of cardiac surgery.
With such a procedure as coronary angiography,complications are rare. This is partly due to injury to the vessel wall, as well as the possibility of infection of the puncture site, the development of phlebitis. Therefore, the question of whether coronarography has contraindications for carrying out, it is worth to answer unequivocally. It is contraindicated in the presence of inflammatory diseases in the places of prospective puncture of the vessel, as well as in the syndrome of a systemic inflammatory response. Also, coronary angiography is not allowed for allergic reactions to the components of the solution used as a contrast. At the same time, the opinion of many doctors about such a diagnostic procedure as coronary angiography, reviews are characterized on the positive side. Patients of cardiological hospitals adhere to similar tendencies.
