Background: Microalbuminuria is a known risk factor for cardiovascular morbidity and mortality suggesting that it should be a marker of endothelial dysfunction. Albumin to creatinine ratio (ACR) is an available and rapid test for microalbuminuria determination, with a high correlation with the 24-h urine collection method. There is no prospective study that evaluates the prognostic value of ACR in patients with non ST-segment elevation acute coronary syndromes (NSTE-ACS). The purpose of our study was to detect the long-term prognostic value of ACR in patients with NSTE-ACS.
Methods: Albumin to creatinine ratio was estimated in 700 patients with NSTE-ACS at SE 0.04, 2 p = 0.03, with a good calibration with both models. Conclusions: Albumin to creatinine ratio is an independent and accessible predictor of long-term adverse outcomes in NSTE-ACS, providing additional value for risk stratification.
