UNASSIGNED: Patients with acute heart failure (AHF) exacerbation are susceptible to complications in the setting of COVID-19 infection. Data regarding the racial/ethnic and sex disparities in patients with AHF and COVID-19 remains limited.
UNASSIGNED: We aim to evaluate the impact of race, ethnicity, and sex on the in-hospital outcomes of AHF with COVID-19 infection using the data from the National Inpatient Sample (NIS).
UNASSIGNED: We extracted data from the NIS (2020) by using ICD-10-CM to identify all hospitalizations with a diagnosis of AHF and COVID-19 in the year 2020. The associations between sex, race/ethnicity, and outcomes were examined using a multivariable logistic regression model.
UNASSIGNED: We identified a total of 158,530 weighted AHF hospitalizations with COVID-19 infection in 2020. The majority were White (63.9 %), 23.3 % were Black race, and 12.8 % were of Hispanic ethnicity, mostly males (n = 84,870 [53.5 %]). After adjustment, the odds of in-hospital mortality were lowest in White females (aOR 0.83, [0.78-0.98]) and highest in Hispanic males (aOR 1.27 [1.13-1.42]) compared with White males. Overall, the odds of cardiac arrest (aOR 1.54 [1.27-1.85]) and AKI (aOR 1.36 [1.26-1.47] were higher, while odds for procedural interventions such as PCI (aOR 0.23 [0.10-0.55]), and placement on a ventilator (aOR 0.85 [0.75-0.97]) were lower among Black males in comparison to White males.
UNASSIGNED: Male sex was associated with a higher risk of in-hospital mortality in white and black racial groups, while no such association was noted in the Hispanic group. Hispanic males had the highest odds of death compared with White males.

BACKGROUND: Severe aortic stenosis (AS) is the most common valvular disease in the USA. Patients undergoing urgent or emergent transcatheter aortic valve replacement (TAVR) have worse clinical outcomes than those undergoing non-urgent procedures. No studies have examined the impact of procedural TAVR timing on outcomes in AS complicated by acute heart failure (AHF).
OBJECTIVE: We aimed to evaluate differences in in-hospital mortality and clinical outcomes between early (<48 hours) vs. late (≥48 hours) TAVR in patients hospitalized with AHF using a real-world US database.
METHODS: We queried the National Inpatient Sample database to identify hospitalizations with a diagnosis of AHF, aortic valve disease, and a TAVR procedure (2015-2020). The associations between TAVR timing and clinical outcomes were examined using logistic regression model.
RESULTS: A total of 25,290 weighted AHF hospitalizations were identified, of which 6,855 patients (27.1%) underwent early TAVR, and 18,435 (72.9%) late TAVR. Late TAVR patients had higher in-hospital mortality rate (2.2% vs. 2.8%, p<0.01) on unadjusted analysis but no significant difference following adjustment for demographic, clinical, and hospital characteristics [aOR 1.00 (0.82-1.23)]. Late TAVR was associated with higher odds of cardiac arrest (aOR 1.50, 95% CI: 1.18-1.90) and use of mechanical circulatory support (aOR 2.05, 95% CI: 1.68-2.51). Late TAVR was associated with longer hospital stay (11 days vs. 4 days, p<0.01) and higher costs ($72,851 vs. $53,209, p<0.01).
CONCLUSIONS: Early TAVR was conducted in approximately 25% of the AS patients admitted with AHF, showing improved in-hospital outcomes before adjustment, with no significant differences observed after adjustment.

BACKGROUND: Diuretic resistance is a relevant clinical issue in acute heart failure (AHF), but a standardized, quantitative definition is still missing. The aim of this analysis was to highlight discrepancies between previously proposed definitions of diuretic response and to propose a new urinary sodium (NaU)-based definition of diuretic efficiency (DE) to identify diuretic resistant (DR) patients.
METHODS: Three historical definitions of diuretic response and a new NaU-based DE definition, evaluating total NaU after the first diuretic bolus per 40 mg furosemide administered, were applied in a retrospective analysis to an AHF population treated with intravenous (i.v.) loop diuretics. Baseline characteristics, in-hospital clinical data and outcomes at discharge and mid-term follow-up were collected and compared among DR and non-DR patients for each definition.
RESULTS: Among 53 patients, 39 (73.6%), 51 (96.2%) and 3 (5.7%) were DR according to weight-derived, diuresis-derived, and spot NaU definition, respectively. The median value of the new NaU-based definition was 31 mmol/40 mg and patients were stratified accordingly. DR patients showed lower cumulative diuresis (5200 mL, 3300-6700 vs 9825, mL 6200-12,200, p = 0.007) and weight loss (4 kg, 1-5 vs 6 kg, 3-8.5, p = 0.023), higher BNP levels (808, 443-1037 vs 351, 209-859, p = 0.062) at the conclusion of protocol-guided i.v diuretic therapy, which was less frequently stopped due to decongestion in DR as compared to non-DR patients (57.7 vs 85.2%, p = 0.026). Six-months mortality or HF hospitalizations were more frequent in DR patients (OR 18.6, 95% CI 2.1-161.2, p = 0.008).
CONCLUSIONS: The NaU-based DE definition might solve discrepancies of other previously proposed definitions.

OBJECTIVE: Early evaluation of the natriuretic response is recommended to guide diuretic therapy in acute decompensated heart failure (ADHF). However, its implementation in daily practice is hampered by implementation barriers and increased time constraints. The Readily Available Urinary Sodium Analysis in Patients with Acute Decompensated Heart Failure (EASY-HF) study assessed the feasibility, efficacy and safety of a nurse-led urinary sodium-based diuretic titration protocol with the use of a point-of-care urinary sodium sensor.
RESULTS: The EASY-HF study was a single-centre, randomized, open-label study comparing diuretic management at the treating physician\'s discretion as standard of care (SOC) with a nurse-led natriuresis-guided protocol in patients with ADHF. The LAQUAtwin Sodium Meter (HORIBA) was used as point-of-care sensor to measure urine sodium concentration. The primary endpoint was natriuresis after 48 h. Secondary endpoints included safety profile and user-friendliness of both the protocol and the point-of-care sensor. Sixty patients were randomized towards SOC (n = 30) versus protocolized care (n = 30). The mean age was 80 ± 8 years, 25% were women and median N-terminal pro-B-type natriuretic peptide was 4667 (2667-7709) ng/L. Natriuresis after 48 h was significantly higher in the protocolized versus SOC group (820 ± 279 vs. 657 ± 273 mmol; p = 0.027). Pre-defined safety endpoints were similar among both groups. The sensor-based protocol was evaluated as easy to use by the nursing staff, and preferred over urinary collections.
CONCLUSIONS: A nurse-led diuretic titration protocol via a point-of-care urinary sodium sensor was feasible, safe and resulted in an increased natriuresis in ADHF compared to SOC.

OBJECTIVE: The aim of this propensity score matched cohort study was to assess the outcomes of telehealth-guided outpatient management of acute heart failure (HF) in our virtual ward (HFVW) compared with hospitalized acute HF patients.
RESULTS: This cohort study (May 2022-October 2023) assessed outcomes of telehealth-guided outpatient acute HF management using bolus intravenous furosemide in a HF-specialist VW. Propensity score matching (PSM) was performed using logistic regression to adjust for potential differences in baseline patient characteristics between HFVW and standard care [Get With The Guidelines-HF score, clinical frailty score (CFS), Charlson co-morbidity index (CCI), NT-proBNP, and ejection fraction]. Clinical outcomes (re-hospitalizations and mortality) were compared at 1, 3, 6, and 12 months versus standard care-SC (acute HF patients managed without telehealth in 2021). Five hundred fifty-four HFVW ADHF patients (age 73.1 ± 10.9 years; 46% female) were compared with 404 ADHF patients (74.2 ± 11.8; P = 0.15 and 49% female) in the standard care-SC cohort. After propensity score matching for baseline patient characteristics, re-hospitalizations were significantly lower in the HFVW compared with SC (1 month-HFVW 8.6% vs. SC-21.5%, P < 0.001; 3 months-21% vs. 30%, P = 0.003; 6 months-28% vs 41%, P < 0.001 and 12 months-47% vs. 57%, P = 0.005) and mortality was also lower at 1 month (5% vs. 13.7%; P < 0.001), 3 months (9.5% vs. 15%; P = 0.001), 6 months (15% vs. 21%; P = 0.03), and 12 months (20% vs. 26%; P = 0.04). Multivariate logistic regression analysis showed that compared with standard care, HFVW management was associated with lower odds of readmission (1-month odds ratio (OR) = 0.3 [95% Confidence Interval CI 0.2-0.5], P < 0.0001; 3 month OR = 0.15 [0.1-0.3], P < 0.0001; 6-month OR = 0.35 [0.2-0.6], P = 0.0002; 12-month OR = 0.25 [0.15-0.4], P ≤ 0.001 and mortality (1-month OR = 0.26 [0.14-0.48], P < 0.0001; 3-month OR = 0.11 [0.04-0.27], P < 0.0001; 6-month OR = 0.35, [0.2; 0.61], P = 0.0002; 12-month OR = 0.6 [0.48; 0.73], P = 0.03. Higher GWTG-HF score independently predicted increased odds of re-hospitalization (1-month OR = 1.2 [1.1-1.3], P < 0.001; 3-month OR = 1.5 [1.37; 1.64], P < 0.0001; 6-month OR = 1.3 [1.2-1.4], P < 0.0001; 12-month OR = 1.1 [1.05-1.2], P = 0.03) as well as mortality (1-month OR = 1.21 [1.1-1.3], P < 0.0001; 3-month OR = 1.3 [1.2-1.4], P < 0.0001; 6-month OR = 1.2 [1.1-1.3], P < 0.0001; 12-month OR = 1.3 [1.1-1.7], P = 0.02). Similarly higher CFS also independently predicted increased odds of re-hospitalizations (1-month OR = 1.9 [1.5-2.4], P < 0.0001; 3-month OR = 1.8 [1.3-2.4], P = 0.0003; 6-month OR = 1.4 [1.1-1.8], P = 0.015; 12-month OR 1.9 [1.2-3], P = 0.01]) and mortality (1-month OR = 2.1 [1.6-2.8], P < 0.0001; 3-month OR = 1.8 [1.2-2.6], P = 0.006; 6-month OR = 2.34 [1.51-5.6], P = 0.0001; 12-month OR = 2.6 [1.6-7], P = 0.02). Increased daily step count while on HFVW independently predicted reduced odds of re-hospitalizations (1-month OR = 0.85[0.7-0.9], P = 0.005), 3-month OR = 0.95 [0.93-0.98], P = 0.003 and 1-month mortality (OR = 0.85 [0.7-0.95], P = 0.01), whereas CCI predicted adverse 12-month outcomes (OR = 1.2 [1.1-1.4], P = 0.03).
CONCLUSIONS: Telehealth-guided specialist HFVW management for ADHF may offer a safe and efficacious alternative to hospitalization in suitable patients. Daily step count in HFVW can help predict risk of short-term adverse clinical outcomes.

OBJECTIVE: Incomplete decongestion due to lack of titration of diuretics to effective doses is a common reason for readmission in patients with acute decompensated heart failure (ADHF). The natriuretic response prediction equation (NRPE) is a novel tool that proved to be rapid and accurate to predict natriuretic response and does not need urine collection. However, the NRPE has not been externally validated. The goal of this study was to externally validate the discrimination capacity of the NRPE in patients with ADHF and fluid overload.
RESULTS: Patients admitted with ADHF who required intravenous loop diuretics were included. A spot urine sample was obtained ~2 h following diuretic administration, and a timed 6-h urine collection by study staff was carried out. Urine sodium and urine creatinine from the spot urine sample were used to predict the 6-h natriuretic response using the NRPE. The primary goal was to validate the NRPE to discriminate poor loop diuretic natriuretic response (sodium output <50 mmol in the 6 h following diuretic administration). The NRPE was compared with urine sodium and measured urine output which are the methods currently recommended by international guidelines to assess diuretic response. Eighty-seven diuretic administrations from 49 patients were analysed. Mean age of patients was 57 ± 17 years and 67% were male. Mean estimated glomerular filtration rate was 65 ± 28 mL/min/1.73 m2, and ejection fraction was 35 ± 15%. Median dose of intravenous furosemide equivalents administered the day of the study was 80 mg (IQR 40 - 160). Poor natriuretic response occurred in 39% of the visits. The AUC of the NRPE to predict poor natriuretic response during the 6-h urine collection was 0.91 (95% CI 0.85-0.98). Compared with the NRPE, spot urine sodium concentration (AUC 0.75) and urine output during the corresponding nursing shift (AUC 0.74) showed lower discrimination capacity.
CONCLUSIONS: In this cohort of patients with ADHF, the NRPE outperformed spot urine sodium concentration and all other metrics related to diuretic response to predict poor natriuretic response. Our findings support the use of this equation at other settings to allow rapid and accurate prediction of natriuretic response.

UNASSIGNED: SCAI classification in cardiogenic shock is simple and suitable for rapid assessment. Its predictive behavior in patients with primary acute heart failure (AHF) is not fully known. We aimed to evaluate the ability of the SCAI classification to predict in-hospital and long-term mortality in AHF.
UNASSIGNED: We conducted a single-center study and performed a retrospective analysis of prospectively collected data of consecutive patients admitted with AHF between 2015 and 2020. The primary end points were in-hospital and long-term mortality from all causes.
UNASSIGNED: In total, 856 patients were included. The unadjusted in-hospital mortality was as follows: A, 0.6%; B, 2.7%; C, 21.5%; D 54.3%; and E, 90.6% (log rank, P < .0001), and long-term mortality was as follows: A, 24.9%; B, 24%; C, 49.6%; D, 62.9%; and E, 95.5% (log rank, P < .0001). After multivariable adjustment, each SCAI SHOCK stage remained associated with increased mortality (all P < .001 compared with stage A). With the exception of the long-term end point, there were no differences between stages A and B for adjusted mortality (P = .1).
UNASSIGNED: In a cohort of patients with AHF, SCAI cardiogenic shock classification was associated with in-hospital and long-term mortality. This finding supports the rationale of the classification in this setting.

UNASSIGNED: Acute heart failure (AHF) is a common emergency department (ED) presentation that may have poor outcomes but often does not require hospital admission. There is little evidence to guide dispositional decisions.
UNASSIGNED: The authors sought to create a risk score for predicting short-term serious outcomes (SSO) in patients with AHF.
UNASSIGNED: We pooled data from 3 prospective cohorts: 2 published studies and 1 new cohort. The 3 cohorts prospectively enrolled patients who required treatment for AHF at 10 tertiary care hospital EDs. The primary outcome was SSO, defined as death <30 days, intubation or noninvasive ventilation (NIV), myocardial infarction, or relapse to ED <14 days. The logistic regression model evaluated 13 predictors, used an AIC-based step-down procedure, and bootstrapped internal validation.
UNASSIGNED: Of the 2,246 patients in the 3 cohorts (N = 559; 1,100; 587), the mean age was 77.4 years, 54.5% were male, 3.1% received intravenous nitroglycerin, 5.2% received ED NIV, and 48.6% were admitted to the hospital. There were 281 (12.5%) SSOs including 70 deaths (3.1%) with many in discharged patients. The final HEARTRISK6 Scale included 6 variables: valvular heart disease, tachycardia, need for NIV, creatinine, troponin, and failed reassessment (walk test). Choosing HEARTRISK6 total-point admission thresholds of ≥1 or ≥2 would yield, respectively, sensitivities of 88.3% (95% CI: 83.9%-91.8%) and 71.5% (95% CI: 65.9%-76.7%) and specificities of 24.7% (95% CI: 22.8%-26.7%) and 50.1% (95% CI: 47.9%-52.4%) for SSO.
UNASSIGNED: Using 3 large prospectively collected datasets, we created a concise and sensitive risk scale for patients with AHF in the ED. Implementation of the HEARTRISK6 scale could lead to safer and more efficient disposition decisions.
