Renoprotective effects of sodium glucose cotransporter 2 inhibitors in type 2 diabetes patients with decompensated heart failure.

ABSTRACT:

Background

Sodium-glucose cotransporter 2 inhibitor (SGLT2i) reduces the risk of the composite renal endpoint and weakens the progressive decline in renal function in patients with chronic heart failure (HF). However, a detailed mechanism of SGLT2i on renal function and outcome remains uninvestigated.

Methods

We prospectively included 40 type 2 diabetic mellitus (T2DM) patients (median 68 years old, 29 male) who were hospitalized for decompensated HF and received SGLT2i during the index hospitalization. Of them, 24 patients had increases in estimated glomerular filtration rate (eGFR) at 12-month follow-up and 16 had decreases in eGFR. We investigated the baseline factors associating with the improvement in renal function.

Results

Lower plasma B-type natriuretic peptide (BNP) level and the use of renin-angiotensin system inhibitor (RASI) were independently associated with increases in eGFR during the follow-up period (p < 0.05 for both). Patients with both low plasma BNP levels and uses of RASI achieved significant increases in eGFR irrespective of the baseline HbA1c levels.

Conclusions

Lower plasma BNP level and the use of RASI at baseline were the key factors contributing to the renoprotective effects of SGLT2i among patients with decompensated HF and T2DM.
