To the Editor. In the recently published study by Lazzeri et al. [1], microalbuminuria and other clinical variables were evaluated in hypertensive, nondiabetic patients with ST elevation myocardial infarction [1]. "The authors concluded that microalbuminuria does not yield prognostic information about the inhospital mortality or complications and claimed an association between acute glucose dysmetabolism and outcomes. We believe that, in this study, the predictive power of microalbuminuria has been overlooked by the authors due to a series of methodological problems.
