Ischemic heart disease (CHD) is one of the main causes of high mortality, disability and reduced quality of life for adults in London. The most common symptom of CHD is angina pectoris, a compressive pain, an overwhelming nature, most often in the sternum that occurs during a load that can be delivered to the left arm, neck, lower jaw. The pain is resting or eliminated by taking nitroglycerin.
The reason for the occurrence of clinical symptoms of coronary heart disease in 98% is narrowing in the vessels that feed the muscle of the heart – the coronary arteries, and there is a mismatch between the delivery and consumption of oxygen at an increased stress on the heart. In this case, in order to confirm the diagnosis and determine the further optimal treatment tactics, in most cases, after standard diagnostic methods (ECG, echocardiography, tests with metered exercise), it is necessary to perform coronary angiography – the “gold standard” in the diagnosis of coronary heart disease.
In stenosis of the vessel more than 70% is shown interference in order to restore its patency, the so-called revascularization. Such recovery of the coronary artery blood flow can be accomplished in two ways: from the inside of the vessel – stenting (implantation of the endoprosthesis) and externally – coronary bypass surgery.
