Background: Chronic kidney disease (CKD) is defined by the KDIGO (Kidney Disease: Improving Global Outcomes) guideline as abnormal kidney structure or function, present for >3 months, with implications for health. KDIGO-defined CKD is associated with poor outcomes in patients with heart failure (HF). Less is known about whether these associations vary by left ventricular ejection fraction.

Objectives: To determine the prevalence and outcomes of KDIGO-defined CKD in heart failure with preserved ejection fraction (HFpEF), heart failure with mildly reduced ejection fraction (HFmrEF), and heart failure with reduced ejection fraction (HFrEF).

Methods: Of the 1,446,053 veterans with an HF diagnosis (1991-2017) in the national Veterans Affairs electronic health record data, 365,000 with data on EF had KDIGO-defined CKD or normal kidney function (NKF). CKD was defined as 2 values measured 90 days apart of estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m² (categorized into 4 eGFR stages based on the last eGFR: 45-59 mL/min/1.73 m², 30-44 mL/min/1.73 m², 15-29 mL/min/1.73 m², and <15 mL/min/1.73 m²) or urinary albumin-to-creatinine ratio (uACR) >30 mg/g (albuminuria). NKF was defined as 2 values measured >90 days apart of eGFR ≥60 mL/min/1.73 m², without eGFR <60 mL/min/1.73 m² or albuminuria for 3 years before HF diagnosis. Patients were categorized into HFpEF (EF ≥50%, n = 85,855), HFmrEF (EF 41%-49%, n = 39,397), and HFrEF (EF ≤40%, n = 139,748). HRs and 95% CIs for 5-year all-cause mortality and HF hospitalization through December 31, 2022, associated with the 5 CKD groups (vs NKF) were estimated using Cox regression.

Results: Among patients with HF and NKF, mortality occurred in 39%, 37%. and 41%, and HF hospitalization occurred in 12%, 15%, and 21% of those with HFpEF, HFmrEF. and HFrEF, respectively. Compared with NKF, CKD was associated with 16%, 19%, and 26% higher multivariable-adjusted risks for death in patients with HFpEF, HFmrEF, and HFrEF, respectively. Respective risks for HF hospitalization were 31%, 33%, and 32% higher. The eGFR-associated risks were incrementally higher with decreasing eGFR, except for eGFR <15 mL/min/1.73 m², likely because of the initiation of dialysis during follow-up. Albuminuria was associated with 16%, 10%, and 12% higher multivariable-adjusted risks for death and 29, 30%, and 24% for HF hospitalization in HFpEF, HFmrEF, and HFrEF, respectively. All associations were statistically significant.

Conclusions: These findings based on KDIGO-defined CKD and NKF provide new information about the best estimates of true prevalence and outcomes of CKD in HFpEF, HFmrEF, and HFrEF.

Background: Neutrophil-to-lymphocyte ratio (NLR) is an easy-to-use inflammatory biomarker. Baseline NLR is independently associated with incident cardiovascular events and all-cause mortality. However, whether this applies to acute myocarditis (AM) has not been evaluated.

Objectives: The present study aimed to investigate the prognostic value of NLR in patients with AM.

Methods: A total of 1,150 consecutive patients with a diagnosis of AM admitted to 10 international tertiary referral cardiac centers were included in the study. The diagnosis was confirmed using cardiac magnetic resonance or endomyocardial biopsy. The primary outcome measure was a composite of all-cause mortality or heart transplantation. Patients were divided into 2 groups according to an NLR cutoff of 4 derived from spline regression analysis and 70:30 train-test split algorithm.

Results: Patients with an NLR <4 were younger and more likely to present with chest pain, and those with an NLR ≥4 were more likely to present with breathlessness and have other comorbidities. Over a median follow-up of 228 weeks, a NLR ≥4 was associated with a worse prognosis (P < 0.0001). After adjustment for prognostic variables, NLR emerged as an independent predictor of outcome (HR: 3.03 [95% CI: 1.30-7.04]; P = 0.010). Elevated NLR remained associated with worse outcomes among patients with preserved ejection fraction at baseline, who are conventionally considered to be at lower risk of adverse events (P < 0.0001).

Conclusions: In patients with AM, elevated NLR is associated with worse prognosis and may be valuable for stratifying patients, even those conventionally considered at low risk.

Background: Acute decompensated heart failure (ADHF) leads to hospitalizations and functional decline in older adults. Although cardiac rehabilitation (CR) is effective for stable heart failure, its impact on ADHF patients, particularly those without frailty, is unclear.

Objectives: The goal of this study was to evaluate the efficacy and safety of early in-hospital CR for patients hospitalized with ADHF who are not frail.

Methods: In this multicenter trial (ACTIVE-ADHF [Effects of Acute Phase Intensive Exercise Training in Patients with Acute Decompensated Heart Failure]), ADHF patients without physical frailty were randomized 2:1 to undergo either exercise-based CR or standard care. The intervention included early mobilization and structured exercise training. The primary outcome was the change in 6-minute walk distance (6MWD) from baseline to discharge. Secondary outcomes assessed physical and cognitive function, quality of life, and safety.

Results: A total of 91 patients were randomized to treatment, with 59 allocated to the intervention group and 32 to the control group. The primary outcome, 6MWD, improved significantly more in the intervention group, with a mean increase of 75.0 ± 7.8 m vs 44.1 ± 10.2 m in the control group, with an effect size of 30.9 ± 13.1 m (95% CI: 4.8-57.0; P = 0.021). The intervention group showed favorable results in secondary efficacy outcomes, including physical and cognitive function, physical activity, and quality of life. Safety outcomes were similar between groups, except for a greater reduction in B-type natriuretic peptide levels at 90 days' postdischarge in the intervention group.

Conclusions: In patients with ADHF without physical frailty, in-hospital exercise-based CR led to significant improvements in 6MWD at 2 weeks after randomization without compromising safety.

Background: Atrial fibrillation (AF) and heart failure (HF) each contributes to global disease burden and can coexist. The interplay of prior HF, prior AF, and presenting rhythm have not previously been jointly considered in prognostic implication.

Objective: The authors sought to assess 1-year all-cause mortality according to permutations of prior HF, prior AF, and AF as presenting rhythm, in a global cohort of patients hospitalized for HF.

Methods: The REPORT-HF registry enrolled patients during hospitalization for acute HF from 44 countries over 6 continents. Cox proportional hazard models were used to compute HRs for the primary outcome of 1-year all-cause mortality.

Results: Of 13,401 participants (median age 67 years, 61% men), 58% had prior HF. AF prevalence (prior or newly detected) at HF admission was 39%, varying by LVEF and race subgroups. Compared with patients with no prior HF, no prior AF, and presenting in sinus rhythm, 1-year all-cause mortality was elevated in patients with prior HF, prior AF, and presenting in AF (adjusted HR: 1.54; 95% CI: 1.34-1.78; P < 0.001) and in patients with prior HF, no prior AF, and presenting in AF (adjusted HR: 1.51, CI: 1.20-1.90, P < 0.001), but not in patients with no prior HF and with prior AF or presenting in AF. These results were conserved across LVEF and race subgroups.

Conclusions: In a global cohort of patients hospitalized for HF, permutations of prior HF, prior AF, and AF as presenting rhythm differentiate outcome. History of prior HF influences the prognostic implications of AF in patients hospitalized for HF. (Global Noninterventional Heart Failure Disease Registry [REPORT-HF]; NCT02595814).

Background: There is limited published information on outcome adjudication in heart failure (HF) trials, particularly in heart failure with preserved ejection fraction (HFpEF).

Objectives: The study sought to compare investigator reports with clinical events committee (CEC) adjudication and assess the impact of the SCTI (Standardized Data Collection for Cardiovascular Trials) criteria.

Methods: In the EMPEROR-Preserved (EMPagliflozin outcome tRial in Patients with chronic heart Failure With Preserved Ejection Fraction) trial, we compared investigator reports with CEC for concordance, treatment effect on primary composite outcome events and components (first event primary heart failure hospitalization [HHF] or cardiovascular [CV] mortality), prognosis after first HHF, total HHF, and trial duration with and without SCTI criteria.

Results: The CEC confirmed 67.4% investigator-reported events for the primary outcome (CV mortality 82.7%, HHF 66.3%). The HR for treatment effect did not differ between adjudication methods for the primary outcome: investigator reports (HR: 0.77; 95% CI: 0.69-0.87), CEC (HR: 0.79; 95% CI: 0.69-0.90), its components, or total HHFs. The prognosis after the first HHF for all-cause mortality and CV mortality also did not differ between investigator reports and the CEC, nor did investigator reports and HHFs with a different CEC cause. SCTI criteria were present in 92% of CEC HHFs with a similar treatment effect to non-SCTI criteria. The investigator-reported primary events reached the protocol target number 6 months earlier than the CEC (7 months with full SCTI criteria).

Conclusions: Investigator adjudication is an alternative to a CEC with similar accuracy and faster event accumulation in HFpEF. The use of granular (SCTI) criteria did not improve trial performance. Our data suggest that a broader definition of an HHF event could be particularly beneficial in HFpEF clinical trials.

Background: Despite being an evidence-based intervention, the implementation of cardiac rehabilitation (CR) is often unsatisfactory, especially among patients with heart failure (HF). Home-based CR can serve as an alternative to improve accessibility for patients unable to participate in center-based programs.

Objectives: The study sought to compare the clinical impact of center- vs home-based CR in HF patients.

Methods: Single-center, parallel group, noninferiority trial, enrolling HF patients irrespective of ejection fraction. Patients were randomly allocated in a 1:1 ratio, then adjusted to a 1 center/2 home ratio during the COVID-19 pandemic, then adjusted to 12 weeks of a standard center-based (24 supervised exercise sessions) or home-based CR (4 supervised sessions plus 20 sessions at home, asynchronously monitored by telephone using wearable smartwatch data) program. The primary outcome was change in peak oxygen uptake (Vo₂peak) at 12 weeks.

Results: Of the 120 patients (age 62 ± 11 years, 66% men, mean left ventricular ejection fraction 36 ± 11%) who were randomized to center-based (n = 45) or home-based (n = 75) CR, 95 (79%) had complete Vo₂peak data at the 12-week assessment: 34 (76%) in the center-based group and 61 (81%) in the home-based group. No significant between-group differences were found in Vo₂peak change from baseline to week 12 (0.8 mL/kg/min [95% CI: 1.8 to -0.16 mL/kg/min]; P = 0.10). Additionally, no between-group differences were found for changes in the prespecified secondary outcomes: 6-minute walking distance, Minnesota Living with Heart Failure Questionnaire scores, disease-related biomarkers, and physical fitness. Exercise adherence to the CR program was similar between groups (home-based 84% vs center-based 81%).

Conclusions: In a contemporary well-treated HF population, home-based CR was noninferior to the center-based program, supporting the home-based approach as an effective and feasible alternative to the traditional center-based programs.

Background: Adverse pregnancy outcomes, such as preterm delivery and hypertensive disorders of pregnancy, may be associated with higher future risks of heart failure (HF). However, the comparative effects of different adverse pregnancy outcomes on long-term risk of HF, and their potential causality, are unclear.

Objectives: The authors sought to examine 5 major adverse pregnancy outcomes in relation to long-term risk of HF in a large population-based cohort.

Methods: A national cohort study was conducted of all 2,201,638 women with a singleton delivery in Sweden in 1973-2015, followed up for HF identified from nationwide outpatient and inpatient diagnoses through 2018. Cox regression was used to compute HRs for HF associated with preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders of pregnancy, and gestational diabetes, while adjusting for other adverse pregnancy outcomes and maternal factors. Co-sibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors.

Results: In 48 million person-years of follow-up, 667,774 women (30%) experienced an adverse pregnancy outcome, and 19,922 women (0.9%) were diagnosed with HF (median age, 61 years). All 5 adverse pregnancy outcomes were independently associated with long-term increased risk of HF. With up to 46 years of follow-up after delivery, adjusted HRs for HF associated with specific adverse pregnancy outcomes were: gestational diabetes, 2.19 (95% CI: 1.95-2.45); preterm delivery, 1.68 (95% CI: 1.61-1.75); other hypertensive disorders, 1.68 (95% CI: 1.48-1.90); preeclampsia, 1.59 (95% CI: 1.53-1.66); and small for gestational age, 1.35 (95% CI: 1.31-1.40). All HRs remained significantly elevated (1.3- to 3.0-fold) even 30 to 46 years after delivery. These findings were only partially explained by shared familial factors. Women with multiple adverse pregnancy outcomes had further increases in risk (eg, up to 46 years after delivery, adjusted HRs associated with 1, 2, or ≥3 adverse pregnancy outcomes were 1.51 [95% CI: 1.47-1.56], 2.31 [95% CI: 2.19-2.45], and 3.18 [95% CI: 2.85-3.56], respectively).

Conclusions: In this large national cohort, women who experienced any of 5 major adverse pregnancy outcomes had increased risk for HF up to 46 years later. Women with adverse pregnancy outcomes need early preventive actions and long-term clinical care to reduce the risk of HF.

Data from large-scale, randomized, controlled trials demonstrate that contemporary treatments for heart failure (HF) can substantially improve morbidity and mortality. Despite this, observed outcomes for patients living with HF are poor, and they have not improved over time. The are many potential reasons for this important problem, but inadequate use of optimal medical therapy for patients with HF, an important component of guideline-directed medical therapy, in routine practice is a principal and modifiable contributor. In this state-of-the-art review, we focus on digital interventions that specifically target the rapid initiation and titration of medical therapy for HF, typically not involving face-to-face encounters. Early data suggest that digital interventions that use data collected outside of structured episodes of care can facilitate initiation and titration of guideline-directed medical therapy for patients with HF. More data are necessary, however, to understand the safety and efficacy of these interventions compared with current care models. In addition, specific efforts by key constituents are necessary to generate sufficient data on the effectiveness and sustainability of digital interventions in routine practice and to ensure that they do not exacerbate existing disparities in care.
