Background : Patients hospitalized for severe COVID-19 infection are at risk for in-hospital cardiac arrest (IHCA). It is unknown whether certain characteristics of cardiac arrest care and outcomes of IHCAs during the COVID-19 pandemic differed compared to a pre-COVID-19 period. Methods : All patients who experienced an IHCA at our hospital from March 1st through May 15th 2020, during the peak of the COVID-19 pandemic, and those who had an IHCA from January 1st 2019 to December 31st 2019 were identified. All patient data was extracted from our hospital's Get With The Guidelines-Resuscitation (GWTG-R) registry, a prospective hospital-based archive of IHCA data. Baseline characteristics of patients, interventions and overall outcomes of IHCAs during the COVID-19 pandemic were compared to IHCAs in 2019, prior to the COVID-19 pandemic. Results : There were 125 IHCAs during a 2.5-month period at our hospital during the peak of the COVID-19 pandemic compared to 117 IHCAs in all of 2019. IHCAs during the COVID-19 pandemic occurred more often on general medicine wards than in intensive care units (46% vs 33%; 19% vs 60% in 2019, p<0.001), were overall shorter in duration (median time of 11 min (8.5-26.5) vs 15 min (7.0-20.0), p=0.001), led to fewer endotracheal intubations (52% vs 85%, p<0.001) and had overall worse survival rates (3% vs 13%, p=0.007) compared to IHCAs prior to the COVID-19 pandemic. Conclusions : Patients who experienced an IHCA during the COVID-19 pandemic had overall worse survival compared to those who had an IHCA prior to the COVID-19 pandemic. Our findings highlight important differences between these two time periods. Further study is needed on cardiac arrest care in patients with COVID-19.
Septic cardiomyopathy and mortalityBackground: Patients with sepsis are at risk for developing sepsis-induced cardiomyopathy (SIC).Previous studies offer inconsistent results regarding the association of SIC and mortality. This study sought to assess whether SIC is linked to mortality in patients with sepsis and to evaluate predictors of the development of SIC.Methods: In this retrospective study, patients admitted to the medical intensive care unit with a diagnosis of sepsis in the absence of acute coronary syndrome were included. SIC was identified using transthoracic echocardiogram and was defined by a new-onset decline in left ventricular ejection fraction (LVEF) of up to 50% or a decline of at least 10% in LVEF relative to baseline in patients with a history of heart failure with reduced EF. Multivariable logistic regression analysis was performed using the R software program (R Foundation for Statistical Computing). Results: Of the 359 patients in the final analysis, 19 (5.3%) had SIC, and eight (42.1%) of these 19 patients and 60 (17.6%) of the 340 patients in the non-SIC group died. SIC was associated with an increased risk for all-cause in-hospital mortality (odds ratio [OR], 4.46; 95% confidence interval [CI], 1.15-18.69; P=0.03). Independent predictors for the development of SIC were albumin level (OR, 0.47; 95% CI, 0.23-0.93; P=0.03) and culture positivity (OR, 8.47; 95% CI, 2.24-55.61; P=0.006). Concomitant right ventricular hypokinesis was noted in 13 (68.4%) of the 19 SIC patients.Conclusions: SIC was associated with an increased risk for all-cause in-hospital mortality. Low albumin level and culture positivity were independent predictors of SIC.
Background Limited evidence-based therapies exist for the management of heart failure with preserved ejection fraction (HFpEF). Sodium-glucose cotransporter-2 inhibitor (SGLT2i) use in patients with systolic heart failure (HFrEF) and type-2-diabetes mellitus (T2DM) is associated with improved cardiovascular (CV) and renal outcomes. Objective We sought to examine whether there is an association of SGLT2i use with improved CV outcomes in patients with HFpEF. Patients and methodsWe conducted a single-center, retrospective review of patients with HFpEF and T2DM. The cohort was divided into two groups based on prescription of a SGLT2i or sitagliptin. The primary outcome was heart failure hospitalization (HFH); secondary outcomes were all-cause hospitalization and acute kidney injury (AKI). Results After propensity score matching, there were 250 patients (89 in the SGLT2i group, 161 in the sitagliptin group), with a mean follow-up of 295 days. Univariate Cox regression analysis showed that the SGLT2i group had a reduced risk of HFH versus the sitagliptin group (hazard ratio (HR) 0.13; 95% confidence interval (CI) (0.05-0.36); p < 0.001). The SGLT2i group had a decreased risk of all-cause hospitalization (HR 0.48; 95% CI (0.33-0.70); p < 0.001) and SGLT2i had a lower risk of AKI (HR 0.39; 95% CI (0.20-0.74); p = 0.004). Conclusions The use of SGLT2is is associated with a reduced incidence of HFH and AKI in patients with HFpEF and T2DM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
