RESUMO
Inflammation plays an important role in the development of atherosclerotic lesions, affecting several stages of the atheroma's development going from the initial leukocyte recruitment to the eventual rupture of the unstable atherosclerotic plaque. The inflammatory reactions within coronary atherosclerotic plaques influence the clinical outcome of acute coronary syndromes and coronary artery disease. Recent studies suggest that inflammation markers may reflect different aspects of the atherothrombotic process in relation to the stages of acute coronary syndrome. These markers play an important role in the risk of developing coronary artery disease, and may correlate with its severity. Some cytokines, acute phase proteins, acute phase reactants proteins, and adhesion molecules released from the inflammatory cells may reflect the inflammatory process in atherosclerotic plaques. However, it remains to be determined whether these pro- and anti-inflammation markers may confer risk or protection for cardiovascular disease, or simply reflect the underlying disease process. The analysis of the markers may be useful for the development of new strategies for coronary disease prevention and treatment. Therefore, we need a well-designed evaluation of these markers before their use in the clinical practice.
