Thus, using a rank correlation analysis, a preliminary analysis of the relationship between the increase / decrease in blood creatinine, blood urea, GFR (Cockcroft-Gault) and GFR (CKD-EPI) after coronary angiography with vascular events was performed. A KaplanMeier survival analysis demonstrated the statistically significant effect of contrast-induced nephropathy on the risk of death from myocardial infarction in patients with long-term acute coronary syndrome.
