Systems biology is an emerging field that offers promise in exploring the inter-connectivity and causality between biological pathways. This review focuses on systems biology approaches in cardiovascular disease and on the role of inflammatory lipid mediators in atherosclerosis. The basic concepts of systems biology are presented, with a focus on the integration of “omics” data from multiple technology platforms, applications of multivariate analysis, and network theory. A particular emphasis is placed on the role of multivariate statistics in analyzing data from omics platforms. An overview of selected systems biology-specific bioinformatics tools is provided, with a focus on applications that explore the role of lipids in cardiovascular systems. Systems biology offers the promise of increased insight into the biological pathways involved in cardiovascular disease and in unraveling the mechanistic relationships arising from lipid-artery interactions that lead to immune and inflammatory responses and the onset of disease.
