Coronary heart disease (CHD) is known to be the largest cause of death globally. This is worrying when considering the substantial investments employed in the research and prevention of CHD. It may be possible that current reductionistic research techniques are not suitable in the study of CHD due to the highly interconnected nature of human biology. It may thus be possible to gain a better understanding of CHD by using a systems engineering approach to develop an integrated model of CHD. An extensive literature review was conducted to develop the integrated model. The model contains information on the pathogenesis, biomarkers, pharmaceuticals and health factors of CHD. Using the integrated model it is possible to analyse typical health factors implicated in CHD progression or mediation. Furthermore, it is possible to analyse pharmaceuticals used in CHD treatment and prevention. Analysis of the integrated model is achieved by using �??connection graphs�?� which elucidate the interactions between health factors or pharmaceuticals and the pathogenesis of CHD through the effect on biomarkers. In this study moderate alcohol consumption and statin therapy were analysed in greater detail by quantifying the biomarker effects. The results indicate that moderate alcohol consumption could decrease CHD risk through actions on coagulation, lipid, metabolic and inflammation as indicated by biomarker quantification. Statin therapy would appear to present increases in CHD risk on coagulation, vascular function and metabolic biomarkers, while decreasing CHD risk through effects on lipid and inflammatory biomarkers.
