Albuminuria has been shown to be associated with mortality and cardiovascular events, independent of traditional cardiovascular risk factors. This suggests that albuminuria may not just represent glomerular damage, but may be a marker of more diffuse endothelial dysfunction. We investigated the relationship between urinary albumin levels after an acute coronary syndrome and cardiovascular outcomes in statin treated subjects after acute coronary syndromes (ACS). Furthermore we assessed the effect of intensive statin treatment on albuminuria among patients in the PROVE IT-TIMI 22 trial, in which patients who had been hospitalized with ACS were randomized to pravastatin 40 mg (standard therapy) or atorvastatin 80 mg daily (intensive therapy). In univariate analyses, increasing urine albumin concentration was associated with increased risk of myocardial infarction, stroke, heart failure, and composite of death, myocardial infarction and stroke at 2 years. However, in a multivariable model containing traditional cardiovascular risk factors, albuminuria was not an independent predictor of the primary PROVE IT endpoint of death, myocardial infarction, unstable angina, revascularization and stroke, and was only an independent predictor of all-cause mortality at urinary albumin concentration >300 mcg/ml. There was no significant change in urinary albumin concentration from enrolment to end of study in either the standard or intensive statin therapy groups, and no significant difference between treatment groups. Our results suggest that after an acute coronary syndrome in statin treated patients, microalbuminuria may reflect traditional cardiovascular risk factor burden and offer little prognostic information independent of those factors.
