Outcomes associated with sodium-glucose cotransporter-2 inhibitor use in acute heart failure hospitalizations complicated by AKI.
This retrospective study examined the association of sodium-glucose cotransporter-2 inhibitor (SGLT2i) use with patients who have KDIGO-defined acute kidney injury (AKI) during acute heart failure (AHF) hospitalizations and their kidney function recovery at 14 days and 30 days using time-varying multivariable Cox-regression analyses. The study looked at 3305 adults hospitalized across 5 Yale New Haven Health Systems between January 2020 and May 2022 with AHF complicated by KDIGO-defined AKI. Of those individuals hospitalized with AHF and AKI, 356 received SGLT2i following AKI diagnosis either as initiation or continuation. The rate of renal recovery was not significantly different among those exposed and unexposed to SGLT2i following AKI (adjusted HR 0.94). SGLT2i exposure was associated with lower risk of 30-day mortality (adjusted HR 0.45). Rates of renal recovery were similar between the exposed and nonexposed cohorts regardless of the proximity of SGLT2i exposure to AKI diagnosis.

Trends in venous thromboembolism anticoagulation in patients hospitalized with COVID-19.
This study’s objective was to characterize frequency, variation across hospitals, and change over time in VTE prophylaxis and treatment-dose anticoagulation in patients hospitalized for COVID-19, as well as the association of anticoagulation strategies with in-hospital and 60-day mortality. This cohort study used adults hospitalized with COVID-19 from 30 pseudorandom hospitals in Michigan from March 7, 2020, to June 17, 2020. Main outcomes measured were the effect of nonadherence and anticoagulation strategies on in-hospital and 60-day mortality. Of a total 1351 patients with COVID-19 with a median age of 64 years, 47.7% women and 48.9% Black, only 18 (1.3%) had a confirmed VTE, and 219 (16.2%) received treatment-dose anticoagulation. Use of treatment-dose anticoagulation without imaging ranged from 0% to 29% across hospitals and increased over time. Of 1127 patients who ever received anticoagulation, 392 missed 2 or more days of prophylaxis. Missed prophylaxis varied from 11% to 61% across hospitals and decreased markedly over time. VTE nonadherence was associated with higher 60-day (adjusted hazard ratio [aHR], 1.31) but not in-hospital mortality (aHR, 0.97). Receiving any dose of anticoagulation (vs no anticoagulation) was associated with lower in-hospital mortality (only prophylactic dose: aHR, 0.36; any treatment dose: aHR, 0.38). However, only the prophylactic dose of anticoagulation remained associated with lower mortality at 60 days (prophylactic dose: aHR, 0.71; treatment dose: aHR, 0.92).

Trends in treatment for patients hospitalized with heart failure with preserved ejection fraction before and after Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT).
This study examined treatment trends for patients hospitalized for heart failure with preserved ejection fraction (HFpEF) after the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, which investigated spironolactone treatment vs placebo in HFpEF patients. This retrospective analysis looked at discharge prescribing data in the Get With The Guidelines-Heart Failure Registry among patients with left ventricular ejection fraction ≥50% discharged between 2009-2016. About 13% of the cohort of 142,201 patients were prescribed mineralocorticoid receptor antagonists (MRAs) at discharge. MRA prescribing increased modestly over time, but the TOPCAT trial did not seem to have an impact.

Diuretic resistance in heart failure.
Diuretic resistance (DR) occurs along a spectrum of relative severity and contributes to worsening of acute heart failure (AHF) during an inpatient stay. This review gives an overview of mechanisms of DR with a focus on loop diuretics and summarizes the current literature regarding the prognostic value of diuretic efficiency and predictors of natriuretic response in AHF.
