Abstract Aims  The incidence and outcomes of a requirement for non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV) in acute heart failure (AHF) hospitalization are not clearly established. Thus, we aimed to characterize the incidence and trends in use of IMV and NIV in AHF and to estimate the magnitude of hazard for mortality associated with requiring IMV and NIV in AHF. Methods and results  We used the National Inpatient Sample (NIS) to identify AHF hospitalizations between 2008 and 2014. The exposure variable of interest was IMV or NIV use within 24 h of hospital admission compared to no respiratory support. We analysed the association between ventilation strategies and in-hospital mortality using Cox proportional hazards models adjusting for demographics and comorbidities. We included 6 534 675 hospitalizations for AHF. Of these, 271 589 (4.16%) included NIV and 51 459 (0.79%) included IMV within the first 24 h of hospitalization and rates of NIV and IMV use increased over time. In-hospital mortality for AHF hospitalizations including NIV was 5.0% and 27% for IMV compared with 2.1% for neither (P < 0.001 for both). In an adjusted model, requirement for NIV was associated with over two-fold higher risk for in-hospital mortality [hazard ratio (HR) 2.10, 95% confidence interval (CI) 2.01–2.19; P < 0.001] and requirement for IMV was associated with over three-fold higher risk for in-hospital mortality (HR 3.39, 95% CI 3.14–3.66; P < 0.001). Conclusion  Respiratory support is used in many AHF hospitalizations, and AHF patients who require respiratory support are at high risk for in-hospital mortality. Our work should inform prospective intervention trials and quality improvement ventures in this high-risk population.

Background: The prevalence and prognostic value of heart failure (HF) stages among elderly hospitalized patients is unclear.Methods: We conducted a prospective, observational, multi-center, cohort study, including hospitalized patients with the sample size of 1,068; patients were age 65 years or more, able to cooperate with the assessment and to complete the echocardiogram. Two cardiologists classified all participants in various HF stages according to 2013 ACC/AHA HF staging guidelines. The outcome was rate of 1-year major adverse cardiovascular events (MACE). The Kaplan–Meier method and Cox proportional hazards models were used for survival analyses. Survival classification and regression tree analysis were used to determine the optimal cutoff of N-terminal pro-brain natriuretic peptide (NT-proBNP) to predict MACE.Results: Participants' mean age was 75.3 ± 6.88 years. Of them, 4.7% were healthy and without HF risk factors, 21.0% were stage A, 58.7% were stage B, and 15.6% were stage C/D. HF stages were associated with worsening 1-year survival without MACE (log-rank χ2 = 69.62, P &lt; 0.001). Deterioration from stage B to C/D was related to significant increases in HR (3.636, 95% CI, 2.174–6.098, P &lt; 0.001). Patients with NT-proBNP levels over 280.45 pg/mL in stage B (HR 2; 95% CI 1.112–3.597; P = 0.021) and 11,111.5 pg/ml in stage C/D (HR 2.603, 95% CI 1.014–6.682; P = 0.047) experienced a high incidence of MACE adjusted for age, sex, and glomerular filtration rate.Conclusions : HF stage B, rather than stage A, was most common in elderly inpatients. NT-proBNP may help predict MACE in stage B.Trial Registration: ChiCTR1800017204; 07/18/2018.

Background/Aims: Aim of our study was to describe the association between natremia (Na) fluctuation and hospital mortality in a general population admitted to a tertiary medical center. Methods: We performed a retrospective observational cohort study on the patient population admitted to the Fondazione Policlinico A. Gemelli IRCCS Hospital between January 2010 and December 2014 with inclusion of adult patients with at least 2 Na values available and with a normonatremic condition at hospital admission. Patients were categorized according to all Na values recorded during hospital stay in the following groups: normonatremia, hyponatremia, hypernatremia, and mixed dysnatremia. The difference between the highest or the lowest Na value reached during hospital stay and the Na value read at hospital admission was used to identify the maximum Na fluctuation. Cox proportional hazards models were used to estimate hazard ratios (HRs) for in-hospital death in the groups with dysnatremias and across quartiles of Na fluctuation. Covariates assessed were age, sex, highest and lowest Na level, Charlson/Deyo score, cardiovascular diseases, cerebrovascular diseases, dementia, congestive heart failure, severe kidney disease, estimated glomerular filtration rate, and number of Na measurements during hospital stay. Results: 46,634 admissions matched inclusion criteria. Incident dysnatremia was independently associated with in-hospital mortality (hyponatremia: HR 3.11, 95% CI 2.53, 3.84, p < 0.001; hypernatremia: HR 5.12, 95% CI 3.94, 6.65, p < 0.001; mixed-dysnatremia: HR 4.94, 95% CI 3.08, 7.92, p < 0.001). We found a higher risk of in-hospital death by linear increase of quartile of Na fluctuation (p trend <0.001) irrespective of severity of dysnatremia (HR 2.34, 95% CI 1.55, 3.54, p < 0.001, for the highest quartile of Na fluctuation compared with the lowest). Conclusions: Incident dysnatremia is associated with higher hospital mortality. Fluctuation of Na during hospital stay is a prognostic marker for hospital death independent of dysnatremia severity.

Background: Policymakers need robust data to respond to the COVID-19 pandemic. We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, the world's largest international, standardised cohort of hospitalised patients. Methods: The dataset analysed includes COVID-19 patients hospitalised between January 2020 and May 2021. We investigated how symptoms on admission, comorbidities, risk factors, and treatments varied by age, sex, and other characteristics. We used Cox proportional hazards models to investigate associations between demographics, symptoms, comorbidities, and other factors with risk of death, admission to intensive care unit (ICU), and invasive mechanical ventilation (IMV). Findings: 439,922 patients with laboratory-confirmed (91.7%) or clinically-diagnosed (8.3%) SARS-CoV-2 infection from 49 countries were enrolled. Age (adjusted hazard ratio [HR] per 10 years 1.49 [95% CI 1.49-1.50]) and male sex (1.26 [1.24-1.28]) were associated with a higher risk of death. Rates of admission to ICU and use of IMV increased with age up to age 60, then dropped. Symptoms, comorbidities, and treatments varied by age and had varied associations with clinical outcomes. Tuberculosis was associated with an 86% higher risk of death, and HIV with an 87% higher risk of death. Case fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients. Interpretation: The size of our international database and the standardized data collection method makes this study a reliable and comprehensive international description of COVID-19 clinical features. This is a viable model to be applied to future epidemics.

Abstract Background Remdesivir (RDV) improved clinical outcomes among hospitalized COVID-19 patients in randomized trials, but data from clinical practice are limited. Methods We examined survival outcomes for US patients hospitalized with COVID-19 between Aug-Nov 2020 and treated with RDV within two-days of hospitalization vs. those not receiving RDV during their hospitalization using the Premier Healthcare Database. Preferential within-hospital propensity score matching with replacement was used. Additionally, patients were also matched on baseline oxygenation level (no supplemental oxygen charges (NSO), low-flow oxygen (LFO), high-flow oxygen/non-invasive ventilation (HFO/NIV) and invasive mechanical ventilation/ECMO (IMV/ECMO) and two-month admission window and excluded if discharged within 3-days of admission (to exclude anticipated discharges/transfers within 72-hrs consistent with ACTT-1 study). Cox Proportional Hazards models were used to assess time to 14-/28-day mortality overall and for patients on NSO, LFO, HFO/NIV and IMV/ECMO. Results 28,855 RDV patients were matched to 16,687 unique non-RDV patients. Overall, 10.6% and 15.4% RDV patients died within 14- and 28-days, respectively compared with 15.4% and 19.1% non-RDV patients. Overall, RDV was associated with a reduction in mortality at 14-days (HR[95% CI]: 0.76[0.70−0.83]) and 28-days (0.89[0.82−0.96]). This mortality benefit was also seen for NSO, LFO and IMV/ECMO at 14-days (NSO:0.69[0.57−0.83], LFO:0.68[0.80−0.77], IMV/ECMO:0.70[0.58−0.84]) and 28-days (NSO:0.80[0.68−0.94], LFO:0.77[0.68−0.86], IMV/ECMO:0.81[0.69−0.94]). Additionally, HFO/NIV RDV group had a lower risk of mortality at 14-days (0.81[0.70−0.93]) but no statistical significance at 28-days. Conclusions RDV initiated upon hospital admission was associated with improved survival among COVID-19 patients. Our findings complement ACTT-1 and support RDV as a foundational treatment for hospitalized COVID-19 patients.

Abstract Background Secondhand smoke (SHS) exposure is a well-established cardiovascular risk factor, yet association between SHS and prognosis of heart failure remains uncertain. Method Data were obtained from the US National Health and Nutrition Examination Surveys III from 1988 to 1994. Currently nonsmoking adults with a self-reported history of heart failure were included. Household SHS exposure was assessed by questionnaire. Participants were followed up through December 31, 2011. Cox proportional-hazards models were used to assess the association of household SHS exposure and mortality risk. Potential confounding factors were adjusted. Results Of 572 currently nonsmoking patients with heart failure, 88 were exposed to household SHS while 484 were not. There were totally 475 deaths during follow-up. In univariate analysis, household SHS was not associated with mortality risk (hazard ratio [HR]: 0.98, 95% confidence interval [CI]: 0.76–1.26, p = 0.864). However, after adjustment for demographic variables, socioeconomic variables and medication, heart failure patients in exposed group had a 43% increase of mortality risk compared with those in unexposed group (HR: 1.43, 95% CI: 1.10–1.86, p = 0.007). Analysis with further adjustment for general health status and comorbidities yielded similar result (HR: 1.47, 95% CI: 1.13–1.92, p = 0.005). Conclusion Household SHS exposure was associated with increased mortality risk in heart failure patients.

Aims: The fatalities case due to coronavirus disease 2019 (COVID-19) is escalating. However, information on critical complications in hospitalized patients of COVID-19 is scant. We aimed to explore the prevalence of acute cardiac injury and its association with in-hospital mortality in COVID-19 patients. Methods: This retrospective study analyzed COVID-19 patients in Union Hospital (Wuhan, China) from Jan 24 to March 18, 2020. Clinical outcomes (discharge, or death) were monitored to April 9, 2020, the latest date of follow-up. Demographic, clinical, laboratory, echocardiographic data, treatment and prognosis were analyzed. Results: A total of 235 COVID-19 patients were included in the final analysis. Their median age was 66 years (interquartile range 57 - 73), and 131 (55.7%) were men. 98 (41.7%) patients were diagnosed with acute cardiac injury, of whom 60 (61.2%) died. There were more comorbidities in those who with acute cardiac injury than those without. A higher proportion of patients with acute cardiac injury received glucocorticoid therapy (68.0% vs 37.0%; P < 0.001), immunoglobulin (53.1% vs 30.1%; P < 0.001) and invasive mechanical ventilation (40.8% vs 6.6%; P < 0.001) than those without. The percentage of patients who were admitted to intensive care unit (39.8 % vs 8.0%; P < 0.001) or died during hospitalization (61.2% vs 8.0%, P < 0.001) were also higher in those with acute cardiac injury. Plasma high-sensitivity troponin I level correlated significantly with plasma interleukin -6, procalcitonin and C-reactive protein levels in COVID-19 patients. Echocardiography showed that cardiac function was attenuated in acute cardiac injury patients. Multivariable Cox proportional hazards regression analysis showed acute cardiac injury was an independent risk factor for higher in-hospital mortality in COVID-19 patients (HR, 3.393; 95% CI, 1.647- 6.987, P <0.001). Conclusions: Acute cardiac injury is a common condition and may be related to inflammatory response in COVID-19 patients. In addition, our study highlights an association between acute cardiac injury and a higher risk of in-hospital mortality. It is suggested that clinicians should be alert to acute cardiac injury in COVID-19 patients and take prompt treatments to improve outcomes.

Background: The extent to which CKD is associated with 30-day and 1-year post ischemic stroke mortality and rehospitalization rates has not been well studied. Methods: Data from 232,236 fee for service Medicare patients admitted with ischemic stroke to 1581 AHA GWTG-Stroke participating hospitals between January 2009 and December 2012 were analyzed. Estimated GFR in mL/min/1.73 m2 was determined based on the MDRD study equation categorized as: no CKD (GFR ≥60); stage 3a CKD (GFR 45-59); stage 3b CKD (GFR 30-44); stage 4 CKD, (GFR 15-29); stage 5 CKD (GFR <15 excluding those on dialysis). Dialysis was identified by ICD-9 codes. Multivariable Cox proportional hazards models adjusted for demographics, medical history, NIHSS, arrival hour, and hospital characteristics were used to determine the independent associations of CKD (reference group those without CKD) with mortality and readmission at 30 days and 1 year. Results: After adjustment, 30-days poststroke mortality was highest among those with CKD stage 5 (HR 1.94, 95%CI 1.72-2.18), even after excluding in-hospital mortality and patients discharged to hospice (HR 2.09, 95%CI 1.66-2.63). Unadjusted 1-year mortality and readmission rates were highest among patients on dialysis (Figure). After adjustment, 1-year post-stroke mortality remained highest among patients on dialysis (HR 2.19, 95%CI 2.08-2.31), even after excluding in-hospital mortality and discharge to hospice (HR 2.65, 95%CI 2.49-2.81). For those discharged alive, 30-day and 1-year rehospitalization rates were also highest among patients on dialysis (HR 2.10, 95%CI 1.95-2.26; HR 2.55, 95%CI 2.44-2.66, respectively) as was the 30-day and 1-year composite of mortality and rehospitalization (HR 2.04, 95%CI 1.90-2.18; HR 2.46, 95% CI 2.36-2.56, respectively). Conclusion: Among Medicare beneficiaries with acute ischemic stroke, poststroke mortality and rehospitalization varied by CKD stage and were highest among those with advanced CKD.

The outcome of patients suffering from out-of-hospital cardiac arrest (OHCA) is very poor, and postresuscitation comorbidities increase long-term mortality. This study aims to analyze new-onset postresuscitation comorbidities in patients who survived from OHCA for over one year. The Taiwan National Health Insurance (NHI) Database was used in this study. Study and comparison groups were created to analyze the risk of suffering from new-onset postresuscitation comorbidities from 2011 to 2012 (until December 31, 2013). The study group included 1,346 long-term OHCA survivors; the comparison group consisted of 4,038 matched non-OHCA patients. Demographics, patient characteristics, and risk of suffering comorbidities (using Cox proportional hazards models) were analyzed. We found that urinary tract infections (n=225, 16.72%), pneumonia (n=206, 15.30%), septicemia (n=184, 13.67%), heart failure (n=111, 8.25%) gastrointestinal hemorrhage (n=108, 8.02%), epilepsy or recurrent seizures (n=98, 7.28%), and chronic kidney disease (n=62, 4.61%) were the most common comorbidities. Furthermore, OHCA survivors were at much higher risk (than comparison patients) of experiencing epilepsy or recurrent seizures (HR = 20.83; 95% CI: 12.24–35.43), septicemia (HR = 8.98; 95% CI: 6.84–11.79), pneumonia (HR = 5.82; 95% CI: 4.66–7.26), and heart failure (HR = 4.88; 95% CI: 3.65–6.53). Most importantly, most comorbidities occurred within the first half year after OHCA.

Abstract Background and Aims Obesity is associated with lower circulating levels of N-terminal pro-BNP (NT-proBNP) both in the general population and in patients with heart failure. In asymptomatic patients with CKD, NT-proBNP levels are generally elevated. The prevalence of obesity is markedly increasing among patients with CKD. However, whether obesity affects NT-proBNP levels and thresholds for increased risk of clinical outcomes is unclear. Method We examined the associations between NT-proBNP and obesity in 408 stage 3–5 CKD patients (268 men and 140 women; mean age 65±13 years) free of heart failure at baseline, who were categorized into 3 groups according to body mass index (BMI; kg/m2) as normal (&lt;24.0), overweight (24.0–27.9), and obese (≥28.0). Multivariate Cox proportional hazards models were used to compare the risk associations of NT-proBNP with the composite of ESKD (needing chronic dialysis or kidney transplantation) or all-cause mortality across BMI categories. Results NT-proBNP levels were significantly lower in obese patients than in normal weight and overweight subjects (P &lt;0.001). Within each CKD stage, NT-proBNP levels decreased with increasing BMI. In a multivariate analysis, NT-proBNP was inversely associated with obesity, as well as BMI and its fat and lean body mass components (all P &lt;0.001), independent of demographics, comorbidities, and severity of CKD. During a median follow-up of 2.2 years, 117 patients progressed to ESKD and 46 patients died. Overall, higher NT-proBNP levels were independently associated with ESKD or death (HR, 1.52; 95% CI, 1.22–1.89). Specifically, higher NT-proBNP levels were consistently associated with poor outcomes in all BMI categories (P for interaction = 0.096). Conclusion Obese CKD patients have significantly lower NT-proBNP levels. Nevertheless, BMI category did not modify the relationship between NT-proBNP and clinical outcomes. Increased risk may be seen at relatively lower levels of NT-proBNP in obese CKD patients.
