Plasma homocysteine and calcific aortic valve disease: Table 1

alcific aortic valve disease and coronary atherosclerotic disease both demonstrate histological features of endothelial disruption and subendothelial accumulation of lipid, lipoprotein, and inflammatory cells. 1 These entities also share acknowledged risk factors, 2 including hypercholesterolaemia, hypertension, and diabetes mellitus, believed to cause disease at least partly via endothelial injury. Data suggest that raised homocysteine concentrations, also associated with endothelial damage, 3 may be an independent risk factor for coronary artery disease. Whether raised homocysteine is a risk factor for calcific aortic valve disease is unknown. We hypothesised that increasing homocysteine concentrations might predict the prevalence of calcific aortic valve disease, specifically aortic sclerosis and aortic stenosis, in a group of patients undergoing cardiac surgery.
