Albuminuria in patients with type 2 diabetes mellitus and newly diagnosed heart failure with preserved ejection fraction

Abstract Funding Acknowledgements None. Aim To evaluate the frequency of albuminuria in patients with type 2 diabetes and newly diagnosed heart failure with preserved ejection fraction Methods 100 patients with T2DM were included (female, 62%; mean age, 64±10 years). Patients were divided into 2 groups with albuminuria (>30 mg albumin/g creatinine) and without albuminuria (<30 mg albumin/g creatinine). HFA-PEFF score was considered as a diagnostic parameter of heart failure with preserved ejection fraction (HFpEF): low probability/excluded HFpEF (<2 points), high probability/confirmed HFpEF (≥5 points), intermediate probability HFpEF (2 -4 points). The detailed echocardiographic criteria for LV diastolic dysfunction (structural parameters), the natriuretic peptide NT-proBNP, urine albumin to creatinine ratio (UACR) were detected in all patients. Results Albuminuria was detected in 55% (n=55) patients with DM, no albuminuria 45% (n=45). Newly diagnosed HFpEF were identified in 46% (n=46) patients, intermediate probability HFpEF in 37% (n=37), low probability/excluded HFpEF in 11% (n=11). Albuminuria was detected in 71% (n=39) of patients with newly diagnosed HFpEF, 22% (n=12) with intermediate probability HF, in 7% (n=4) with excluded HFpEF. In patients with HFpEF albuminuria was associated with the following echo parameters with: E/e’>9(r=0,51; p < 0,001) and Left ventricular mass index (LVMI) ≥115 g/m² (male) or ≥95 g/m² (female) (r=0,68; p < 0,001). Conclusions In patients with type 2 diabetes and newly diagnosed HFpEF the frequency of albuminuria was significantly high and was associated with echo parameters E/e’ ratio and LVMI.
