Clinical studies performed in last few years proved great role of inflammatory processes in development of atherosclerosis. Inflammatory markers indicating unstable atherosclerotic plaque were isolated. These biomarkers are used in diagnostics and identification of patients with unstable angina pectoris and miocardial infarct. Moreover usefulness of proinflammatory markers in indicating patients with high cardiovascular risk was confirmed. In result different markers of inflammation found their use in diagnostics of patients with stable and unstable coronary artery disease.
