Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF patients (SECSI Registry).
2021
ABSTRACT Recent studies have proven benefit of SGLT2i drugs in patients with heart failure with reduced ejection fraction (HFrEF), but their safety when combined with ARNI has not been established. The SECSI registry was conducted to address this issue. SECSI registry is a consecutive, observational, retrospective, multicentre study carried out in three Heart Failure Units in Spain. It included 144 HFrEF patients who were treated with ARNI and iSGLT2. Data were collected at baseline, month two and month six. The primary endpoint was the estimated glomerular filtration rate (eGFR), after the initiation of angiotensin-neprilysin inhibitor (ARNI) and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Secondary endpoints included potassium levels and functional class [New York Heart Association (NYHA) class]. There were three prespecified subgroup analyses: Elderly patients (≥70 years), patients with chronic kidney disease (KDIGO classification G3) and the sequence of drug initiation. Mean age was 69.9±10.1 years, and 110(76.4%) were men. Left ventricular ejection fraction was 32±7.8%, and most patients were symptomatic [123(87.2%) NYHA II/III/IV]. eGFR decreased at month two and this trend was maintained at month six (eGFR baseline 68.5±17.3, month two 62±19.7 and month six 64.7±8.6 ml/min/1.73m2 [p<0.01 for both]). In prespecified analysis, elder patients and those who simultaneously initiate both treatments showed the steeper decrease in eGFR. To conclude, co-administration of SGLT2i and ARNI in routine care in HFrEF patients produced a slight decrease in eGFR at 6 months of follow-up. This decrease was especially significant in elder patients and those who initiate both drugs simultaneously.
