Abstract
In half of cases during coronary angiography (CAG), obstructive coronary artery lesions aren’t detected in patients with chronic coronary artery disease. Such patients mostly have vasospastic angina (VSA) and/or microvascular angina (MVA). These patients can be performed repeated diagnostic tests, including selective coronary angiography, but as a result they are never diagnosed correctly. This review presents modern pathogenetic mechanisms for the development and methods of diagnosing of ischemia with non-obstructive coronary artery disease. It also highlights choice of treatment tactics in accordance with the identified pathophysiological mechanism for the development of chronic coronary artery disease.
