Abstract
Objective: Currently, it’s not well known what factors influenced the incidence of heart failure with preserved ejection (HFpEF) fraction in patients receiving sodium glucose co-transporter 2 inhibitors (SGLT2i). Objective: To evaluate predictors of HFpEF in patients with type 2 diabetes mellitus (T2DM) receiving SGLT2i Design and method: It was a prospective study in patients with T2DM. Inclusion criteria were: male and female, age 40–65 years, T2DM with duration at least for 1 year, absence of established atherosclerotic cardiovascular disease and HF. Exclusion criteria were: type 1 diabetes mellitus, glycated hemoglobin (HbA1c)> 11% at screening, insulin therapy, atrial fibrillation, clinically significant valvular heart disease, chronic kidney disease, other serious conditions that would make the patient unsuitable for participation in the study. Clinical, laboratory (including biomarkers such as NT-proBNP, sST2, galectin-3, PICP,PIIINP,MMP-9,TIMP-1) and instrumental (echocardiography) data were collected at baseline. Empagliflozin 10 mg daily was prescribed for all patients. After 3 years of follow-up, information about HF events (hospitalization for HF, established HF in outpatient department by cardiologist), other clinically important data were obtained. Results: Seventy-five patients were included in the study. The mean age was 58 (47.9;65.1) years, 45,1% were female. Most patients had T2DM for more than 4 years. Mean HbA1c was 8.6% (7.6;9.5), all patients received oral antihyperglycemic medications. After 3 years of follow-up HFpEF was established in 16 patients. The HF group had higher waist circumference values, higher Nt-proBNP, galectin-3 and P1CP levels at baseline than patients without HF (all p < 0.05). The threshold for galectin-3 level associated with increased risk of HFpEF in this population was 10.3 ng/ml (AUC area = 0.86; sensitivity, 87%; and specificity, 73%; p < 0.001). Multiple logistic regression analysis identified significant risk factors for new onset of HFpEF: age> 60 years, diabetes duration> 10 years and presence of abdominal obesity were independent predictors of HFpEF. Galectin-3 level > 10 ng/ml was associated with increased risk of HF incidence (OR = 2.15; 95% CI, 1.80–5.21; p = 0.01). Conclusions: Predictors for incidence HFpEF in patients with T2DM were age, diabetes duration, presence of abdominal obesity and galectin-3 levels higher than 10 ng/ml.
