Abstract		Proteinuria and estimated glomerular filtration rate (eGFR) are markers of chronic kidney disease (CKD) and cardiovascular disease. With applanation tonometry, pulse wave analysis and many hemodynamic data are available. One of them is the subendocardial viability ratio (SEVR) which represents a non-invasive measure of myocardial perfusion related to the work of the heart. The aim of our study was to investigate the importance of SEVR in proteinuric CKD patients and healthy subjects. We performed a cross-sectional study in a cohort of 90 non-dialysis CKD patients and 39 healthy controls. SEVR was assessed by radial applanation tonometry (SphygmoCor, Atcor, Australia). Blood samples and urine albumin-to-creatinine ratio (UACR) were analyzed. CKD patients were divided in four groups according to the UACR and eGFR: CKD group 1: UACR>1000 mg/g and eGFR<30 mL/min; CKD group 2: UACR>1000 mg/g and eGFR >30 mL/min; CKD group 3: UACR <1000 mg/g and eGFR<30 mL/min and CKD group 4: UACR<1000 mg/g and eGFR >30 mL/min. Using one-way ANOVA, we found a statistically significant difference in SEVR only between CKD group 1 and all other CKD groups and healthy control group (P<0.022). Results of our study show that only CKD patients with UACR more than 1000 mg/g and eGFR below 30 mL/min have significantly lower SEVR.
