#1122 Anaemia in CKD and cardiovascular risk; all cut from the same cloth?

Abstract Background and Aims Anaemia in chronic kidney disease (CKD) has been repeatedly associated with increased cardiovascular morbidity and mortality, but most studies have not investigated its longitudinal association by sex and age. Our aim was to study the association between haemoglobin (Hb) current value and the hazard of major adverse cardiovascular event (MACE) in specific subgroups of CKD patients defined by age and sex. Because erythropoiesis-stimulating agents (ESA) are incriminated to modify the effect of Hb level on the hazard of event for high level of Hb, we have here only focused in non-ESA users CKD patients. Method We used data from the CKD-REIN cohort, which included 3033 patients with moderate to severe CKD from 40 nationally representative nephrology clinics in France between 2013 and 2016. We included patients with at least one Hb, estimated glomerular filtration rate (eGFR), transferrin saturation (TSAT) or ferritin measurement. We studied all Hb measurements available until a first MACE defined as the first event among cardio-vascular death, myocardial infarction, stroke or hospitalization for acute heart failure; initiation of kidney replacement therapy; death from other causes; or initiation of ESA therapy, whichever came first. First, we estimated the individual trajectories of Hb, eGFR, TSAT, ferritin using multivariate share random effect joint model. Then, we estimated the association between Hb current value and MACE using a cause specific multivariate Cox model in 4 specific subgroups separately: women ≤ and >70 years, men ≤ and >70 years. All models were adjusted on current value of eGFR, TSAT, Ferritin, and baseline value of albumin-to-creatinine ratio, age, CKD aetiology, heart failure past history, alcohol consumption, iron treatment, antithrombotic and anticoagulant. When appropriate, spline functions were used for continuous variables to account for potential non-linear effects. Reference value of Hb for computing hazard ratio was 12 g/dL in women, and 13 in men according to current definition of anaemia. Results A total of 2742 patients were included in the analysis (median eGFR 33 ml/min/1.73 m2, median age at inclusion 69 years) together with 28423 Hb measurements (median of 13 per patient) collected during a median follow-up of 5.0 years. There were 551 women ≤70 (median Hb 12.4 g/dL, 34 (6.2%) MACE), 349 women > 70 (12.2 g/dL, 61 (17.5%) MACE), 1009 men ≤ 70 (13.4 g/dL, 104 (10.3%) MACE) and 833 men > 70 (13.0 g/dL, 163 (19.6%) MACE). No statistical significant association was found in males whatever their age (Hazard ratio of MACE for each 1 g/dL increase in Hb 1.0 (95% CI 0.9-1.1) in men < 70 and 0.9 (95% CI 0.8-1.1) in men > 70). For women, the hazard of MACE raised as the Hb values decreased, with a more pronounced increase in women > 70 (Fig. 1). For example, the hazard ratio for a Hb value of 10 g/dL compared to the reference was 2.0 (95% CI 0.9-4.7) in women < 70 and 3.3 (95% CI 1.5-7.2) in women > 70. Conclusion In non-ESA users CKD patients, anaemia is associated with the occurrence of MACE in females, especially those older than 70 years. These results raise question about a one-size-fits-all approach in the interpretation of low values of haemoglobin and anaemia management. It also suggests to evaluate the effect of anaemia therapies in men and women separately.

#2334 Elevated serum admission creatinine in acute heart failure hospitalizations: lifting the veil to understand outcome differences

Abstract Background and Aims Organ crosstalk in heart failure and kidney dysfunction is prevalent and is associated to a high event rate. In this setting elevated serum creatinine (sCr) at acute decompensated heart failure (ADHF) admissions is a strong risk factor for poor outcomes. Current accepted cardiorenal syndrome (CRS) classification is based on timing and initial organ dysfunction and fails at capturing its nature and prognosis. We sought to describe patient (P) profile and outcomes in P hospitalized for ADHF with high admission sCr in function of current CRS classification and assess for stratifying predictors. Method We conducted an observational, analytical and cross-sectional study, with prospective and consecutive data acquisition. We included P over 18 years-old, who were admitted to the Intensive Care Telemetry Unit in our Hospital between July, 2011 and Dec, 2023 due to ADHF. P who received a heart transplant during index admission or those on chronic dialysis were excluded. Clinical, epidemiological and biochemical variables were registered. Renal dysfunction was defined under admission sCr >1.4 mg/dl and divided according to Ronco et al classification, as initially cardiac (type 2) or renal (type 4) origin. We constructed multivariate logistic and survival regression models, with selection of relevant predictors by resampling and regularization of a Lasso regression model. Statistical significance was considered with a 5% of alpha error level. Analysis was conducted using R (R Core Team, 2023). Results A total of 1868 consecutive P were included. P population consisted in type 2: 124 and type 4: 258 P, respectively. We found no differences in gender (p = 0.47), while type 4 were older (75 ± 12 vs 71 ± 12; p < 0.01). Ventricular dysfunction was more severe in type 2 (left ventricular ejection fraction 34 ± 17 vs 41 ± 16%; p < 0.001). While ischaemic heart disease was more prevalent in type 4 (32.8 vs 23.5%; p = 0.001), idiopathic cardiomyopathy was more frequent in type 2 (18.8 vs 7.2%; p = 0.001). Clinical phenotypes differed between groups, being clinical hypoperfusion more frequent in type 2 (32.4 vs 12.3%; p < 0.001). Admission sCr was higher in type 4 (1.9 [0.8] vs 1.6 [0.58] mg/dl; p < 0.001), as was 1st day natriuresis (81 vs 67 mEq; p = 0.01). Both groups experienced a similar diuretic resistance rate (21.2 vs 17.1%; p = 0.34), while type 4 received rescue ultrafiltration more frequently (11.3 vs 3.5%; p < 0.01). Type 2 received a higher inotropic support rate (47.1 vs 19.5%; p < 0.01) and had a longer length of stay (9 vs 7 days; p = 0.01). In-hospital (11.8 vs 11.3%; p = 0.99); 6-month and 1-year mortality rates (66.8 vs 72.8% and 55.1 vs 64.6% respectively; p = 0.3). In a similar way, 1-month (94.8 vs 94.7%), 6-month (72 vs 74.7%) and 1-year readmission rates (59.2 vs 60.9%; p = 0.6) were similar in both groups. A multiple logistic regression model (AUCROC 0.82) identified admission sCr (OR 2.6; CI 95% 2.2-3.2; p < 0.001), inotropic need (OR 1.87; CI 95% 1.4-2.6; p < 0.001), anasarca phenotype (OR 1.63; CI 95% 1.06-2.5; p = 0.02), moderate to severe right ventricular dysfunction (OR 1.4; CI 95% 1.03-1.9; p = 0.03) as independent predictors for a descending sCr behavior during hospitalization, while the lower T3 levels were associated with less probability for a descent of sCr (OR 0.21; CI 95% 0.1-0.46; p < 0.001). Conclusion Organ crosstalk in ADHF hospitalizations was associated with a high event rate. One-year mortality and readmission rates were similar in both groups. Renal support therapies were more frequent under lower kidney reserve conditions. Ventricular dysfunction and systemic congestion phenotype are relevant to a better understanding for potential reversibility at the admission time and may promote actions for outcome enhancing.

#83 Cardiovascular outcomes in home hemodialysis and peritoneal dialysis patients

Abstract Background and Aims Cardiovascular disease is the leading cause of morbidity and mortality in patients with end-stage kidney disease. Little is known about differences in cardiovascular outcomes between home hemodialysis (HHD) and peritoneal dialysis (PD). Methods We evaluated 68 645 patients who initiated home dialysis between 1/1/2005 and 12/31/2018 using the United States Renal Data System with linked Medicare claims. Rates for incident cardiovascular events of acute coronary syndrome, heart failure, and stroke hospitalizations were determined. Using adjusted time-to-event models, the associations of type of home dialysis modality with the outcomes of incident cardiovascular events, cardiovascular death, and all-cause death were examined. Results The mean age of patients in the study cohort was 64 ± 15 years, and 42.3% were women. Mean time of follow up was 1.8 ± 1.6 years. The unadjusted cardiovascular event rate was 95.1 per thousand person-years [PTPY] (95% CI, 93.6-96.8), with a higher rate in patients on HHD than on PD (127.8 PTPY; 95% CI, 118.9-137.2 vs. 93.3 PTPY; 95% CI, 91.5-95.1). However, HHD was associated with a slightly lower adjusted risk of cardiovascular events than PD (HR, 0.92; 95% CI, 0.85 to 0.997). Compared to PD patients, HHD patients had 42% lower adjusted risk of stroke (HR, 0.58; 95% CI, 0.48-0.71), 17% lower adjusted risk of acute coronary syndrome (HR, 0.83; 95% CI, 0.72-0.95), and no difference in risk of heart failure (HR, 1.05; 95% CI, 0.94-1.16). HHD was associated with 22% lower adjusted risk of cardiovascular death (HR, 0.78; 95% CI, 0.71-0.86) and 8% lower adjusted risk of all-cause death (HR, 0.92; 95% CI, 0.87-0.97) as compared to PD. Conclusion Relative to PD, HHD is associated with decreased risk of stroke, acute coronary syndrome, cardiovascular death, and all-cause death. Further studies are needed to better understand the factors associated with differences in cardiovascular outcomes by type of home dialysis modality in patients with kidney failure.

The utility of qSOFA in assessing outcomes of patients with acute heart failure in a level II hospital: a single-center retrospective analysis

Abstract Funding Acknowledgements None. Introduction High all-cause mortality is associated with acute heart failure (AHF) hospitalization, both when the condition first develops and when it worsens. Although there are several risk models for patients with chronic heart failure (CHF), it is unknown whether these scoring systems may be applied to patients with ADHF to predict their chance of developing the condition. Purpose Acute Heart failure (AHF) patients benefit from accurate risk assessment. Those stratified with worse prognosis may benefit more from continuous and close monitoring, with subsequent prompt intervention in case of deterioration. Currently, there is a lack of a universally accepted risk score that can accurately predict outcomes in acute heart failure (AHF). Undeniably, sepsis and AHF share several clinical features. These similarities encourage the sepsis-to-AHF translation of SOFA and qSOFA scores. We compared different scoring systems used in sepsis and assessed their predictive accuracy. Methodology This retrospective study included all patients with acute heart failure admitted in a private teaching hospital between January 2014 and January 2023. This study included newly admitted adult patients with new-onset AHF or acute on chronic heart failure. Baseline qSOFA, SIRS, and SOFA values were determined. Receiver Operating Characteristics - Area under the Curve (ROC-AUC) analysis assessed these scores' ability to predict mortality, whereas chi-square and Fischer's exact test assessed secondary outcome risk. Results 545 patients were included in the study. The majority were males with a mean age of 65 years. Most patients in the study required oxygen support, were classified as NOHRIA A, and with NYHA Functional Class II. Renal and respiratory failures were prominent upon arrival. About 11% met ≥2 points in qSOFA. Therein, systolic BP of <100 mmHg was the most frequent criterion met. The primary endpoint, that is in-hospital mortality, occurred in 9.52% of patients. A positive qSOFA, defined as a score of 2 or more, was consistent in the majority of those meeting the primary endpoint (Chi2 = 264.698, p<0.001). The ROC analysis of qSOFA (AUC 0.949, 95% CI 0.924–0.974, accuracy of 73%), SOFA (AUC 0.935, 95% CI 0.887–0.983, accuracy of 72%), and SIRS criteria (AUC 0.939, 95% CI 0.917–0.961, accuracy of 72%) show no fundamental differences regarding the prediction of the primary endpoint. Patients with positive qSOFA criteria were more frequently affected by organ failure (OR 5.386, p <0.001), needed more vasopressors (OR 4.921, p < 0.001), notably with an ejection fraction <40% (OR 3.363, p <0.001), and required mechanical ventilator support more often (OR 3.794, p<0.001). Conclusion In conclusion, qSOFA used in Acute Heart Failure is a valuable tool in the early detection of in-hospital mortality and detection of worse outcomes, hence should be considered when making therapeutic strategies and decisions.AUC for Primary OutcomesSecondary Outcomes

Chlorthalidone vs Hydrochlorothiazide for Hypertension Treatment After Myocardial Infarction or Stroke

Patients with prior myocardial infarction (MI) or stroke have a greater risk of recurrent cardiovascular (CV) events. To evaluate the association of chlorthalidone (CTD) vs hydrochlorothiazide (HCTZ) with CV outcomes and noncancer deaths in participants with and without prior MI or stroke. This was a prespecified secondary analysis of the Diuretic Comparison Project (DCP), a pragmatic randomized clinical trial conducted within 72 participating Veterans Affairs health care systems from June 2016 to June 2021, in which patients aged 65 years or older with hypertension taking HCTZ at baseline were randomized to continue HCTZ or switch to CTD at pharmacologically comparable doses. This secondary analysis was performed from January 3, 2023, to February 29, 2024. Pharmacologically comparable daily dose of HCTZ or CTD and history of MI or stroke. Outcome ascertainment was performed from randomization to the end of the study. The primary outcome consisted of a composite of stroke, MI, urgent coronary revascularization because of unstable angina, acute heart failure hospitalization, or noncancer death. Additional outcomes included achieved blood pressure and hypokalemia (potassium level <3.1 mEq/L; to convert to mmol/L, multiply by 1.0). The DCP randomized 13 523 participants to CTD or HCTZ, with a mean (SD) study duration of 2.4 (1.4) years. At baseline, median age was 72 years (IQR, 69-75 years), and 96.8% were male. Treatment effect was evaluated in subgroups of participants with (n = 1455) and without (n = 12 068) prior MI or stroke at baseline. There was a significant adjusted interaction between treatment group and history of MI or stroke. Participants with prior MI or stroke randomized to CTD had a lower risk of the primary outcome than those receiving HCTZ (105 of 733 [14.3%] vs 140 of 722 [19.4%]; hazard ratio [HR], 0.73; 95% CI, 0.57-0.94; P = .01) compared with participants without prior MI or stroke, among whom incidence of the primary outcome was slightly higher in the CTD arm compared with the HCTZ arm (597 of 6023 [9.9%] vs 535 of 6045 [8.9%]; HR, 1.12; 95% CI, 1.00-1.26; P = .054) (P = .01 for interaction). The incidence of a nadir potassium level less than 3.1 mEq/L and hospitalization for hypokalemia differed among those with and without prior MI or stroke when comparing those randomized to CTD vs HCTZ, with a difference only among those without prior MI or stroke (potassium level <3.1 mEq/L: prior MI or stroke, 43 of 733 [5.9%] vs 37 of 722 [5.1%] [P = .57]; no prior MI or stroke, 292 of 6023 [4.9%] vs 206 of 6045 [3.4%] [P < .001]; hospitalization for hypokalemia: prior MI or stroke, 14 of 733 [1.9%] vs 16 of 722 [2.2%] [P = .72]; no prior MI or stroke: 84 of 6023 [1.4%] vs 57 of 6045 [0.9%] [P = .02]). Results of this secondary analysis of the DCP trial suggest that CTD may be associated with reduced major adverse CV events and noncancer deaths in patients with prior MI or stroke compared with HCTZ.

Differential sex-related effect of left ventricular ejection fraction trajectory on the risk of mortality and heart failure readmission following hospitalization for acute heart failure: A longitudinal study.

There is limited information on the sex-specific longitudinal changes of left ventricular ejection fraction (LVEF) after an acute heart failure (AHF) hospitalization. We aimed to investigate whether LVEF trajectories over time and their impact on mortality and AHF readmission rates differ between men and women. We conducted a retrospective sex-specific analysis of longitudinal LVEF measurements (n = 9581) in 3383 patients with an index hospitalization for AHF in a single tertiary-level hospital. Statistical techniques suited for longitudinal data analysis were used. The mean age of the sample was 73.8 ± 11.2 years, and 47.9% were women. The mean LVEF was 49.4 ± 15.3%. At a median follow-up of 2.58 years (interquartile range 0.77-5.62), we registered 2197 deaths (64.9%) and 2597 AHF readmissions in 1302 (38.5%) patients. The longitudinal analysis showed that women had consistently higher LVEF values throughout the follow-up with both trajectories characterized by an early peak-approximately at 1 year-followed by decreasing values in men but a plateau in women. Multivariate between-sex comparisons across LVEF categories revealed that women had lower rates of AHF readmissions when LVEF ≤40%. On the contrary, women displayed an excess risk of AHF readmissions when LVEF >60%. A trend in the same direction was found for cardiovascular and all-cause mortality. Sex was a significant factor in determining the follow-up trajectory of LVEF and predicting differences in outcomes after an AHF admission. The findings suggest that women have a higher risk of AHF readmissions at higher LVEF values, while men have a higher risk at lower LVEF values. For all-cause and cardiovascular mortality, the same direction of the association was inferred but they were not significant.

N-terminal pro-B-type natriuretic peptide post-discharge monitoring in the management of patients with heart failure and preserved ejection fraction-a randomized trial: The NICE study.

There is a lack of specific studies assessing the impact of natriuretic peptide monitoring in the post-discharge management of patients with heart failure (HF) and preserved ejection fraction (HFpEF), throughout the vulnerable phase following acute HF hospitalization. The NICE study aims to assess the clinical benefit of incorporating N-terminal pro-B-type natriuretic peptide (NT-proBNP) into the post-discharge management of HFpEF patients. Individuals admitted with HFpEF (left ventricular ejection fraction >50%) were included in a multicentre randomized controlled study employing an open-label design with event blinding (NCT02807168). Upon discharge, 157 patients were randomly allocated to either NT-proBNP monitoring (n = 79) or no access to NT-proBNP (control group, n = 78) during pre-scheduled visits at 2, 4 and 12 weeks. Clinical endpoints were evaluated at 6 months. The primary endpoint of HF rehospitalizations occurred in 12.1% patients, without significant differences observed between the NT-proBNP monitoring group (12.8%) and the control group (11.4%) (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.47-2.81, p = 0.760). Regarding secondary endpoints, the NT-proBNP monitoring group demonstrated a significantly lower risk of death (1.3% vs. 10.1%; HR 0.12, 95% CI 0.02-0.98; p = 0.048), whereas non-HF hospitalizations (12.8% vs. 19.0%, p = 0.171) and any adverse clinical event (26.9% vs. 36.7%, p = 0.17) did not reach statistical significance [Correction added on 29 April 2024, after first online publication: In the preceding sentence, "95% CI 0.02 - 0.09" has been corrected to "95% CI 0.02 - 0.98; p = 0.048" in this version.]. Awareness of NT-proBNP levels were associated with higher doses of diuretics and renin-angiotensin system inhibitors (angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers) in the NT-proBNP monitoring group. Post-discharge monitoring of NT-proBNP in HFpEF patients did not exhibit an association with reduced rates of HF hospitalization in this study. Nonetheless, it appears to enhance global clinical management by optimizing medical therapies and contributing to improved overall survival.

Efficacy and Safety of Dapagliflozin in Patients With Acute Heart Failure

BackgroundThe primary goals during acute heart failure (AHF) hospitalization are decongestion and guideline-directed medical therapy (GDMT) optimization. Unlike diuretics or other GDMT, early dapagliflozin initiation could achieve both AHF goals. ObjectivesThe authors aimed to assess the diuretic efficacy and safety of early dapagliflozin initiation in AHF. MethodsIn a multicenter, open-label study, 240 patients were randomized within 24 hours of hospital presentation for hypervolemic AHF to dapagliflozin 10 mg once daily or structured usual care with protocolized diuretic titration until day 5 or hospital discharge. The primary outcome, diuretic efficiency expressed as cumulative weight change per cumulative loop diuretic dose, was compared across treatment assignment using a proportional odds model adjusted for baseline weight. Secondary and safety outcomes were adjudicated by a blinded committee. ResultsFor diuretic efficiency, there was no difference between dapagliflozin and usual care (OR: 0.65; 95% CI: 0.41-1.02; P = 0.06). Dapagliflozin was associated with reduced loop diuretic doses (560 mg [Q1-Q3: 260-1,150 mg] vs 800 mg [Q1-Q3: 380-1,715 mg]; P = 0.006) and fewer intravenous diuretic up-titrations (P ≤ 0.05) to achieve equivalent weight loss as usual care. Early dapagliflozin initiation did not increase diabetic, renal, or cardiovascular safety events. Dapagliflozin was associated with improved median 24-hour natriuresis (P = 0.03) and urine output (P = 0.005), expediting hospital discharge over the study period. ConclusionsEarly dapagliflozin during AHF hospitalization is safe and fulfills a component of GDMT optimization. Dapagliflozin was not associated with a statistically significant reduction in weight-based diuretic efficiency but was associated with evidence for enhanced diuresis among patients with AHF.

The effects of oxygenation on acute vasodilator challenge in pulmonary arterial hypertension.

Identification of long-term calcium channel blocker (CCB) responders with acute vasodilator challenge is critical in the evaluation of patients with pulmonary arterial hypertension. Currently there is no standardized approach for use of supplemental oxygen during acute vasodilator challenge. In this retrospective analysis of patients identified as acute vasoresponders, treated with CCBs, all patients had hemodynamic measurements in three steps: (1) at baseline; (2) with 100% fractional inspired oxygen; and (3) with 100% fractional inspired oxygen plus inhaled nitric oxide (iNO). Those meeting the definition of acute vasoresponsiveness only after first normalizing for the effects of oxygen in step 2 were labeled "iNO Responders." Those who met the definition of acute vasoresponsiveness from a combination of the effects of 100% FiO2 and iNO were labeled "oxygen responders." Survival, hospitalization for decompensated right heart failure, duration of CCB monotherapy, and functional data were collected. iNO responders, when compared to oxygen responders, had superior survival (100% vs. 50.1% 5-year survival, respectively), fewer hospitalizations for acute decompensated right heart failure (0% vs. 30.4% at 1 year, respectively), longer duration of CCB monotherapy (80% vs. 52% at 1 year, respectively), and superior 6-min walk distance. Current guidelines for acute vasodilator testing do not standardize oxygen coadministration with iNO. This study demonstrates that adjusting for the effects of supplemental oxygen before assessing for acute vasoresponsiveness identifies a cohort with superior functional status, tolerance of CCB monotherapy, and survival while on long-term CCB therapy.

Predicting One-Year Mortality after Discharge Using Acute Heart Failure Score (AHFS).

Background: Acute heart failure (AHF) represents a leading cause of unscheduled hospital stays, frequent rehospitalisations, and mortality worldwide. The aim of our study was to develop a bedside prognostic tool, a multivariable predictive risk score, that is useful in daily practice, thus providing an early prognostic evaluation at admission and an accurate risk stratification after discharge in patients with AHF. Methods: This study is a subanalysis of the STADE HF study, which is a single-centre, prospective, randomised controlled trial enrolling 123 patients admitted to hospital for AHF. Here, 117 patients were included in the analysis, due to data exhaustivity. Regression analysis was performed to determine predictive variables for one-year mortality and/or rehospitalisation after discharge. Results: During the first year after discharge, 23 patients died. After modellisation, the variables considered to be of prognostic relevance in terms of mortality were (1) non-ischaemic aetiology of HF, (2) elevated creatinine levels at admission, (3) moderate/severe mitral regurgitation, and (4) prior HF hospitalisation. We designed a linear model based on these four independent predictive variables, and it showed a good ability to score and predict patient mortality with an AUC of 0.84 (95%CI: 0.76-0.92), thus denoting a high discriminative ability. A risk score equation was developed. During the first year after discharge, we observed as well that 41 patients died or were rehospitalised; hence, while searching for a model that could predict worsening health conditions (i.e., death and/or rehospitalisation), only two predictive variables were identified: non-ischaemic HF aetiology and previous HF hospitalisation (also included in the one-year mortality model). This second modellisation showed a more discrete discriminative ability with an AUC of 0.67 (95% C.I. 0.59-0.77). Conclusions: The proposed risk score and model, based on readily available predictive variables, are promising and useful tools to assess, respectively, the one-year mortality risk and the one-year mortality and/or rehospitalisations in patients hospitalised for AHF and to assist clinicians in the management of patients with HF aiming at improving their prognosis.

Abstract P531: Contralateral Differences in Ankle Systolic Blood Pressure and Pulse Wave Velocity: Associations With Incident Heart Failure and Mortality

Introduction: Contralateral differences in systolic blood pressure (SBP) are a risk assessment tool and indicative of underlying cardiovascular issues. Most of the available studies focused on brachial blood pressure and its clinical impact. This study evaluated whether interankle SBP differences and contralateral differences in pulse wave velocity (PWV) are associated with incident heart failure (HF) and all-cause and cardiovascular mortality in a community-dwelling sample of older adults. Methods: Sample included 5,077 participants (75.2 ± 5.1 years old) of the Atherosclerosis Risk in Communities (ARIC) study. The OMRON VP-1000 plus was used to measure PWV and blood pressure in the ankles. PWV was assessed between the brachial artery and ankle (baPWV) and heart and ankle (haPWV) on the right and left sides. Cut points for contralateral differences in PWV were set at the 90th percentile in our sample. Outcomes included incident HF (first definite or probable hospitalization for acute decompensated HF), all-cause and cardiovascular mortality (until December 31, 2020). Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI). Results: Over a mean follow-up of 7.5 ± 2.1 years, incident HF was diagnosed in 457 participants, and 1,275 all-cause and 363 cardiovascular deaths occurred. The prevalence of interankle SBP difference ≥10 and ≥15 mmHg was 24.9% (1,268) and 12.0% (605), respectively. The prevalence of contralateral differences in baPWV (&gt;240 cm/s) and haPWV (&gt;80 cm/s) was 10.1% (513) and 9.1% (464), respectively. Interankle SBP difference ≥10 mmHg (HR 1.13; 95% CI 1.00-1.29), ≥15 mmHg (HR 1.25; 95% CI 1.06-1.48), contralateral difference in baPWV &gt;240 cm/s (HR 1.18; 95% CI 1.00-1.41), and haPWV &gt;80 cm/s (HR 1.21; 95% CI 1.01-1.44) were each independently associated with all-cause mortality after adjustment for demographics, traditional cardiovascular risk factors, and extreme values of ankle-brachial index ≤0.9 or &gt;1.40. Contralateral differences in ankle SBP ≥15 mmHg (HR 1.55; 95% CI 1.16-2.06), and haPWV &gt;80 cm/s (HR 1.40; 95% CI 1.02-1.91) were both independently associated with cardiovascular mortality. Crude analysis revealed that those with contralateral differences in ankle SBP ≥10 and ≥15 mmHg, baPWV &gt;240 cm/s, and haPWV &gt;80 cm/s had a significantly higher risk of HF (p&lt;0.05 for all). However, these HF relationships were no longer statistically significant after adjustment for confounders. Conclusions: Contralateral differences in ankle SBP and PWV were independently associated with all-cause and cardiovascular mortality risk even after accounting for traditional cardiovascular risk factors and the ankle-brachial index. These results underscore the significance of evaluating contralateral differences in ankle SBP and PWV as potential markers of increased mortality risk among older adults.

Timing of previous heart failure hospitalization as a prognostic factor for emergency department heart failure patients.

To investigate whether the timing of a previous hospital admission for acute heart failure (AHF) is a prognostic factor for AHF patients revisiting the emergency department (ED) in the subsequent 12-month follow-up. All ED AHF patients enrolled in the previously described EAHFE registry were stratified by the presence or absence of an AHF hospitalization admission in the prior 12months. The primary outcome was 12-month all-cause mortality postED visit. Secondary end points were hospital admission, prolonged hospitalization (> 7days), mortality during hospitalization and a 90-day post-discharge adverse composite event (ACE) rate, defined as ED revisits due to AHF, hospitalizations due to AHF, or all-cause mortality. Outcomes were adjusted for baseline and AHF episode characteristics.Of 5,757 patients included, the median age was 84years (IQR 77-88); 57% were women, and 3,759 (65.3%) had an AHF hospitalization in the previous 12months. The 12-month mortality was 37% (41.7% vs. 28.3% p < 0.001), hospital admission was 76.1% (78.8% vs. 71.1% p < 0.001) ACE was 60.2% (65.1% vs. 50.5% p < 0.001). In the adjusted analysis, patients with AHF hospitalization in the prior 12months had a higher mortality (HR = 1.41; 95% CI 1.27-1.56), 90-day ACE rate (HR = 1.45: 95% CI 1.32-1.59), and more hospital admissions (OR = 1.32; 95% CI 1.16-1.51), with shorter times since the previous hospitalization being related to the outcomes analyzed. One-year mortality, adverse events at 90days, and readmission rates are increased in ED AHF patients previously admitted within the last 12months.

Immediate pharmacotherapy intensification after cardiac resynchronization therapy: incidence, characteristics, and impact.

Cardiac resynchronization therapy (CRT) is an established treatment for drug-refractory heart failure (HF) in patients with left bundle branch block (LBBB). Acute haemodynamic improvement after CRT implantation may enable the intensification of HF medication soon thereafter. Immediate pharmacotherapy intensification (IPI) after CRT implantation achieves a synergetic effect, possibly leading to a better prognosis. This study aimed to explore the incidence, characteristics, and impact of IPI on real-world outcomes among CRT recipients with a history of hospitalization for acute HF. This multicentre retrospective study enrolled CRT recipients with LBBB morphology, a QRS width ≥120ms, a left ventricular ejection fraction ≤35%, and New York Heart Association II-IV HF symptoms. All patients had previous HF hospitalizations within the previous year and received guideline-directed medical therapy before CRT implantation. Patient baseline characteristics, including HF medication, were collected. IPI was defined as the intensification of beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists within 30days of CRT implantation. The primary endpoint was all-cause death or first hospitalization for HF; the secondary endpoint was all-cause death. We enrolled 194 patients (75% male; mean age, 65±13years; 78% with non-ischaemic cardiomyopathy). One hundred five (54%) patients received IPI. Patients who received IPI exhibited a significantly shorter QRS duration (159±26 vs. 171±32ms; P=0.004), higher estimated glomerular filtration rate (55.2±20.0 vs. 47.8±24.7mL/min/1.73m2 ; P=0.022), and more dilated cardiomyopathy. During a median follow-up period of 29months, 70 (36%) patients reached the primary endpoint and 42 (22%) patients died. Patients with IPI showed significantly better outcomes for the primary and secondary endpoints than patients without IPI. The volumetric responder ratio at 6months after implantation was not significantly different between patients with and without IPI; however, patients who received IPI had reduced mortality even at 6months after implantation. In the multivariate analysis, IPI was an independent predictor of the primary endpoint (hazard ratio, 0.51; 95% confidence interval, 0.27-0.97; P=0.043). Immediate intensification of HF medication was achieved in 54% of CRT recipients and was significantly higher in patients without excessive QRS prolongation, preserved renal function, and dilated cardiomyopathy than others. In patients with LBBB morphology and QRS≥120ms, IPI was associated with a significantly better prognosis and fewer HF hospitalizations after CRT implantation than others.

Blood pressure and intensive treatment up-titration after acute heart failure hospitalization: Insights from the STRONG-HF trial.

A high-intensity care (HIC) strategy with rapid guideline-directed medical therapy (GDMT) up-titration and close follow-up visits improved outcomes, compared to usual care (UC), in patients recently hospitalized for acute heart failure (AHF). Hypotension is a major limitation to GDMT implementation. We aimed to assess the impact of baseline systolic blood pressure (SBP) on the effects of HIC versus UC and the role of early SBP changes in STRONG-HF. A total of 1075 patients hospitalized for AHF with SBP ≥100 mmHg were included in STRONG-HF. For the purpose of this post-hoc analysis, patients were stratified by tertiles of baseline SBP (<118, 118-128, and ≥129 mmHg) and, in the HIC arm, by tertiles of changes in SBP from the values measured before discharge to those measured at 1 week after discharge (≥2 mmHg increase, ≤7 mmHg decrease to <2 mmHg increase, and ≥8 mmHg decrease). The primary endpoint was 180-day heart failure rehospitalization or death. The effect of HIC versus UC on the primary endpoint was independent of baseline SBP evaluated as tertiles (pinteraction = 0.77) or as a continuous variable (pinteraction = 0.91). In the HIC arm, patients with increased, stable and decreased SBP at 1 week reached 83.5%, 76.2% and 75.3% of target doses of GDMT at day 90. The risk of the primary endpoint was not significantly different between patients with different SBP changes at 1 week (adjusted p = 0.46). In STRONG-HF, the benefits of HIC versus UC were independent of baseline SBP. Rapid GDMT up-titration was performed also in patients with an early SBP drop, resulting in similar 180-day outcome as compared to patients with stable or increased SBP.

Cardiovascular Outcomes in Patients on Home Hemodialysis and Peritoneal Dialysis.

Cardiovascular disease is the leading cause of morbidity and mortality in patients with end-stage kidney disease. Little is known about differences in cardiovascular outcomes between home hemodialysis (HHD) and peritoneal dialysis (PD). We evaluated 68,645 patients who initiated home dialysis between 1/1/2005 and 12/31/2018 using the United States Renal Data System with linked Medicare claims. Rates for incident cardiovascular events of acute coronary syndrome, heart failure, and stroke hospitalizations were determined. Using adjusted time-to-event models, the associations of type of home dialysis modality with the outcomes of incident cardiovascular events, cardiovascular death, and all-cause death were examined. The mean age of patients in the study cohort was 64±15 years, and 42.3% were women. Mean time of follow up was 1.8±1.6 years. The unadjusted cardiovascular event rate was 95.1 per thousand person-years [PTPY] (95% CI, 93.6-96.8), with a higher rate in patients on HHD than on PD (127.8 PTPY; 95% CI, 118.9-137.2 vs. 93.3 PTPY; 95% CI, 91.5-95.1). However, HHD was associated with a slightly lower adjusted risk of cardiovascular events than PD (HR, 0.92; 95% CI, 0.85 to 0.997). Compared to PD patients, HHD patients had 42% lower adjusted risk of stroke (HR, 0.58; 95% CI, 0.48-0.71), 17% lower adjusted risk of acute coronary syndrome (HR, 0.83; 95% CI, 0.72-0.95), and no difference in risk of heart failure (HR, 1.05; 95% CI, 0.94-1.16). HHD was associated with 22% lower adjusted risk of cardiovascular death (HR, 0.78; 95% CI, 0.71-0.86) and 8% lower adjusted risk of all-cause death (HR, 0.92; 95% CI, 0.87-0.97) as compared to PD. Relative to PD, HHD is associated with decreased risk of stroke, acute coronary syndrome, cardiovascular death, and all-cause death. Further studies are needed to better understand the factors associated with differences in cardiovascular outcomes by type of home dialysis modality in patients with kidney failure.

Short-Stay Units vs Routine Admission From the Emergency Department in Patients With Acute Heart Failure

More than 80% of patients who present to the emergency department (ED) with acute heart failure (AHF) are hospitalized. With more than 1 million annual hospitalizations for AHF in the US, safe and effective alternatives are needed. Care for AHF in short-stay units (SSUs) may be safe and more efficient than hospitalization, especially for lower-risk patients, but randomized clinical trial data are lacking. To compare the effectiveness of SSU care vs hospitalization in lower-risk patients with AHF. This multicenter randomized clinical trial randomly assigned low-risk patients with AHF 1:1 to SSU or hospital admission from the ED. Patients received follow-up at 30 and 90 days post discharge. The study began December 6, 2017, and was completed on July 22, 2021. The data were analyzed between March 27, 2020, and November 11, 2023. Randomized post-ED disposition to less than 24 hours of SSU care vs hospitalization. The study was designed to detect at least 1-day superiority for a primary outcome of days alive and out of hospital (DAOOH) at 30-day follow-up for 534 participants, with an allowance of 10% participant attrition. Due to the COVID-19 pandemic, enrollment was truncated at 194 participants. Before unmasking, the primary outcome was changed from DAOOH to an outcome with adequate statistical power: quality of life as measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). The KCCQ-12 scores range from 0 to 100, with higher scores indicating better quality of life. Of the 193 patients enrolled (1 was found ineligible after randomization), the mean (SD) age was 64.8 (14.8) years, 79 (40.9%) were women, and 114 (59.1%) were men. Baseline characteristics were balanced between arms. The mean (SD) KCCQ-12 summary score between the SSU and hospitalization arms at 30 days was 51.3 (25.7) vs 45.8 (23.8) points, respectively (P = .19). Participants in the SSU arm had 1.6 more DAOOH at 30-day follow-up than those in the hospitalization arm (median [IQR], 26.9 [24.4-28.8] vs 25.4 [22.0-27.7] days; P = .02). Adverse events were uncommon and similar in both arms. The findings show that the SSU strategy was no different than hospitalization with regard to KCCQ-12 score, superior for more DAOOH, and safe for lower-risk patients with AHF. These findings of lower health care utilization with the SSU strategy need to be definitively tested in an adequately powered study. ClinicalTrials.gov Identifier: NCT03302910.

Rates of diabetic ketoacidosis with empagliflozin use during hospitalization for acute heart failure.

There is concern that sodium-glucose cotransporter-2 inhibitorsduring hospitalization for acute heart failure (aHF) may precipitate diabetic ketoacidosis (DKA). A retrospective study of all hospitalization encounters for aHF defined by a primary HF International Classification of Diseases (ICD)-10 code in 15 Kaiser Permanente Southern California medical centers hospitalized between January 1, 2021 and August 31, 2023 was performed to describe rates of DKA with empagliflozin use. DKA was defined by the presence of either a DKA ICD-10 code or ketoacidosis lab criteria (bicarbonate <18 mmol/L and urine ketone 1+ or more or elevated serum beta-hydroxybutyrate within 12 h) during hospitalization. Among 21,630 hospital encounters (15,518 patients) for aHF, 1678 (8%) had empagliflozin use. There were 2 (0.1%) probable DKA cases in empagliflozin encounters and 15 (0.1%) in nonexposed encounters. These rates were similar when stratified by diabetes status and ejection fraction. Empagliflozin may be safe during aHF hospitalization.
