Abstract

BACKGROUND: Cystatin C is the most abundant protease inhibitor in the plasma. Low plasma levels have been found in patients with aortic aneurysms and they seem correlated with the extension of the aortic lesions in early aneurysms detected by ultrasonography. METHODS: In this study, plasma levels of cystatin C have been investigated in patients with acute myocardial infarction (AMI), unstable angina and controls. The effect on plasma levels of the G73A polymorphism of the CST3 gene has been also evaluated. RESULTS: Patients with acute myocardial infarction showed significantly lower levels of cystatin C compared to unstable angina and controls, but levels were nearly normal in a week after the acute event. The genotype distribution of the G73A polymorphism was not different among the groups. Nevertheless, cystatin C levels decreased proportionally with the number of A alleles. Cystatin C levels were positively correlated with age, triglyceride/HDL cholesterol ratio and creatinine, and negatively with HDL cholesterol and the number of A alleles. All variables, but not HDL cholesterol, were independently correlated in a multivariate analysis. CONCLUSIONS: Cystatin C is decreased in acute myocardial infarction. It is still not clear whether lower cystatin C levels are causally linked to the acute event or just represent a negative acute phase response. The CST3 gene G73A polymorphism functionally affects cystatin C plasma levels.
