Item Open Access Association Between Comorbidities and Outcomes in Heart Failure Patients With and Without an Implantable Cardioverter-Defibrillator for Primary Prevention.(J Am Heart Assoc, 2015-08-06) Khazanie, Prateeti; Hellkamp, Anne S; Fonarow, Gregg C; Bhatt, Deepak L; Masoudi, Frederick A; Anstrom, Kevin J; Heidenreich, Paul A; Yancy, Clyde W; Curtis, Lesley H; Hernandez, Adrian F; Peterson, Eric D; Al-Khatib, Sana MBACKGROUND: Implantable cardioverter-defibrillator (ICD) therapy is associated with improved outcomes in patients with heart failure (HF), but whether this association holds among older patients with multiple comorbid illnesses and worse HF burden remains unclear. METHODS AND RESULTS: Using the National Cardiovascular Data Registry's ICD Registry and the Get With The Guidelines-Heart Failure (GWTG-HF) registry linked with Medicare claims, we examined outcomes associated with primary-prevention ICD versus no ICD among HF patients aged ≥65 years in clinical practice. We included patients with an ejection fraction ≤35% who received (ICD Registry) and who did not receive (GWTG-HF) an ICD. Compared with patients with an ICD, patients in the non-ICD group were older and more likely to be female and white. In matched cohorts, the 3-year adjusted mortality rate was lower in the ICD group versus the non-ICD group (46.7% versus 55.8%; adjusted hazard ratio [HR] 0.76; 95% CI 0.69 to 0.83). There was no associated difference in all-cause readmission (HR 0.99; 95% CI 0.92 to 1.08) but a lower risk of HF readmission (HR 0.88; 95% CI 0.80 to 0.97). When compared with no ICD, ICDs were also associated with better survival in patients with ≤3 comorbidities (HR 0.77; 95% CI 0.69 to 0.87) and >3 comorbidities (HR 0.77; 95% CI 0.64 to 0.93) and in patients with no hospitalization for HF (HR 0.75; 95% CI 0.65 to 0.86) and at least 1 prior HF hospitalization (HR 0.69; 95% CI 0.58 to 0.82). In subgroup analyses, there were no interactions between ICD and mortality risk for comorbidity burden (P=0.95) and for prior HF hospitalization (P=0.46). CONCLUSION: Among older HF patients, ICDs for primary prevention were associated with lower risk of mortality even among those with high comorbid illness burden and prior HF hospitalization.Item Open Access Clinical Outcomes With Metformin and Sulfonylurea Therapies Among Patients With Heart Failure and Diabetes.(JACC. Heart failure, 2022-03) Khan, Muhammad Shahzeb; Solomon, Nicole; DeVore, Adam D; Sharma, Abhinav; Felker, G Michael; Hernandez, Adrian F; Heidenreich, Paul A; Matsouaka, Roland A; Green, Jennifer B; Butler, Javed; Yancy, Clyde W; Peterson, Pamela N; Fonarow, Gregg C; Greene, Stephen JObjectives
The authors sought to characterize associations between initiation of metformin and sulfonylurea therapy and clinical outcomes among patients with comorbid heart failure (HF) and diabetes (overall and by ejection fraction [EF] phenotype).Background
Metformin and sulfonylureas are frequently prescribed to patients with diabetes for glycemic control. The impact of these therapies on clinical outcomes among patients with comorbid HF and diabetes is unclear.Methods
The authors evaluated Medicare beneficiaries hospitalized for HF in the Get With The Guidelines-Heart Failure Registry between 2006 and 2014 with diabetes and not prescribed metformin or sulfonylurea before admission. In parallel separate analyses for metformin and sulfonylurea, patients with newly prescribed therapy within 90 days of discharge were compared with patients not prescribed therapy. Multivariable models landmarked at 90 days evaluated associations between prescription of therapy, and mortality and hospitalization for HF (HHF) at 12 months. Negative control (falsification) endpoints included hospitalization for urinary tract infection, hospitalization for gastrointestinal bleed, and influenza vaccination. Prespecified subgroup analyses were stratified by EF ≤40% versus >40%.Results
Of 5,852 patients, 454 (7.8%) were newly prescribed metformin and 504 (8.6%) were newly prescribed sulfonylurea. After adjustment, metformin prescription was independently associated with reduced risk of composite mortality/HHF (HR: 0.81; 95% CI: 0.67-0.98; P = 0.03), but individual components were not statistically significant. Findings among patients with EF >40% accounted for associations with mortality/HHF (HR: 0.68; 95% CI: 0.52-0.90) and HHF (HR: 0.58; 95% CI: 0.40-0.85) endpoints (all P for interaction ≤0.04). After adjustment, sulfonylurea initiation was associated with increased risk of mortality (HR: 1.24; 95% CI: 1.00-1.52; P = 0.045) and HHF (HR: 1.22; 95% CI: 1.00-1.48; P = 0.050) with nominal statistical significance. Associations between sulfonylurea initiation and endpoints were consistent regardless of EF (all P for interaction >0.11). Neither metformin initiation nor sulfonylurea initiation were associated with negative control endpoints.Conclusions
In this population of older U.S. adults hospitalized for HF with comorbid diabetes, metformin initiation was independently associated with substantial improvements in 12-month clinical outcomes, driven by findings among patients with EF >40%. By contrast, sulfonylurea initiation was associated with excess risk of death and HF hospitalization, regardless of EF.Item Open Access Clinician's guide to the updated ABCs of cardiovascular disease prevention.(Journal of the American Heart Association, 2014-09) Kohli, Payal; Whelton, Seamus P; Hsu, Steven; Yancy, Clyde W; Stone, Neil J; Chrispin, Jonathan; Gilotra, Nisha A; Houston, Brian; Ashen, M Dominique; Martin, Seth S; Joshi, Parag H; McEvoy, John W; Gluckman, Ty J; Michos, Erin D; Blaha, Michael J; Blumenthal, Roger STo facilitate the guideline-based implementation of treatment recommendations in the ambulatory setting and to encourage participation in the multiple preventive health efforts that exist, we have organized several recent guideline updates into a simple ABCDEF approach. We would remind clinicians that evidence-based medicine is meant to inform recommendations but that synthesis of patient-specific data and use of appropriate clinical judgment in each individual situation is ultimately preferred.Item Open Access Initiation, Continuation, or Withdrawal of Angiotensin-Converting Enzyme Inhibitors/Angiotensin Receptor Blockers and Outcomes in Patients Hospitalized With Heart Failure With Reduced Ejection Fraction.(J Am Heart Assoc, 2017-02-11) Gilstrap, Lauren G; Fonarow, Gregg C; Desai, Akshay S; Liang, Li; Matsouaka, Roland; DeVore, Adam D; Smith, Eric E; Heidenreich, Paul; Hernandez, Adrian F; Yancy, Clyde W; Bhatt, Deepak LBACKGROUND: Guidelines recommend continuation or initiation of guideline-directed medical therapy, including angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARB), in hospitalized patients with heart failure with reduced ejection fraction. METHODS AND RESULTS: Using the Get With The Guidelines-Heart Failure Registry, we linked clinical data from 16 052 heart failure with reduced ejection fraction (ejection fraction ≤40%) patients with Medicare claims data. We divided ACEi/ARB-eligible patients into 4 categories based on admission and discharge ACEi/ARB use: continued (reference group), started, discontinued, or not started on therapy. A multivariable Cox proportional hazard model was used to determine the association between ACEi/ARB category and outcomes. Most, 90.5%, were discharged on ACEi/ARB (59.6% continued and 30.9% newly started). Of those discharged without ACEi/ARB, 1.9% were discontinued, and 7.5% were eligible but not started. Thirty-day mortality was 3.5% for patients continued and 4.1% for patients started on ACEi/ARB. In contrast, 30-day mortality was 8.8% for patients discontinued (adjusted hazard ratio [HRadj] 1.92; 95% CI 1.32-2.81; P<0.001) and 7.5% for patients not started (HRadj 1.50; 95% CI 1.12-2.00; P=0.006). The 30-day readmission rate was lowest among patients continued or started on therapy. One-year mortality was 28.2% for patients continued and 29.7% for patients started on ACEi/ARB compared to 41.6% for patients discontinued (HRadj 1.35; 95% CI 1.13-1.61; P<0.001) and 41.7% (HRadj 1.28; 95% CI 1.14-1.43; P<0.001) for patients not started on therapy. CONCLUSIONS: Compared with continuation, withdrawal of ACEi/ARB during heart failure hospitalization is associated with higher rates of postdischarge mortality and readmission, even after adjustment for severity of illness.Item Open Access Kidney Outcomes Among Medicare Beneficiaries After Hospitalization for Heart Failure.(JAMA cardiology, 2024-05) Ostrominski, John W; Greene, Stephen J; Patel, Ravi B; Solomon, Nicole C; Chiswell, Karen; DeVore, Adam D; Butler, Javed; Heidenreich, Paul A; Huang, Joanna C; Kittleson, Michelle M; Joynt Maddox, Karen E; Linganathan, Karthik K; McDermott, James J; Owens, Anjali Tiku; Peterson, Pamela N; Solomon, Scott D; Vardeny, Orly; Yancy, Clyde W; Fonarow, Gregg C; Vaduganathan, MuthiahImportance
Kidney health has received increasing focus as part of comprehensive heart failure (HF) treatment efforts. However, the occurrence of clinically relevant kidney outcomes in contemporary populations with HF has not been well studied.Objective
To examine rates of incident dialysis and acute kidney injury (AKI) among Medicare beneficiaries after HF hospitalization.Design, setting, and participants
This retrospective cohort study evaluated adults aged 65 years or older who were hospitalized for HF across 372 sites in the Get With The Guidelines-Heart Failure registry in the US between January 1, 2014, and December 31, 2018. Patients younger than 65 years or requiring dialysis either during or prior to hospitalization were excluded. Data were analyzed from May 4, 2021, to March 8, 2024.Main outcomes and measures
The primary outcome was inpatient dialysis initiation in the year after HF hospitalization and was ascertained via linkage with Medicare claims data. Other all-cause and cause-specific hospitalizations were also evaluated. The covariate-adjusted association between discharge estimated glomerular filtration rate (eGFR) and 1-year postdischarge outcomes was examined using Cox proportional hazards regression models.Results
Overall, among 85 298 patients included in the analysis (mean [SD] age, 80 [9] years; 53% women) mean (SD) left ventricular ejection fraction was 47% (16%) and mean (SD) eGFR was 53 (29) mL/min per 1.73 m2; 54 010 (63%) had an eGFR less than 60 mL/min per 1.73 m2. By 1 year after HF hospitalization, 6% had progressed to dialysis, 7% had progressed to dialysis or end-stage kidney disease, and 7% had been readmitted for AKI. Incident dialysis increased steeply with lower discharge eGFR category: compared with patients with an eGFR of 60 mL/min per 1.73 m2 or more, individuals with an eGFR of 45 to less than 60 and of less than 30 mL/min per 1.73 m2 had higher rates of dialysis readmission (45 to <60: adjusted hazard ratio [AHR], 2.16 [95% CI, 1.86-2.51]; <30: AHR, 28.46 [95% CI, 25.25-32.08]). Lower discharge eGFR (per 10 mL/min per 1.73 m2 decrease) was independently associated with a higher rate of readmission for dialysis (AHR, 2.23; 95% CI, 2.14-2.32), dialysis or end-stage kidney disease (AHR, 2.34; 95% CI, 2.24-2.44), and AKI (AHR, 1.25; 95% CI, 1.23-1.27), with similar findings for all-cause mortality, all-cause readmission, and HF readmission. Baseline left ventricular ejection fraction did not modify the covariate-adjusted association between lower discharge eGFR and kidney outcomes.Conclusions and relevance
In this study, older adults with HF had substantial risk of kidney complications, with an estimated 6% progressing to dialysis in the year after HF hospitalization. These findings emphasize the need for health care approaches prioritizing kidney health in this high-risk population.Item Open Access Patterns of Referral and Postdischarge Utilization of Cardiac Rehabilitation Among Patients Hospitalized With Heart Failure: An Analysis From the GWTG-HF Registry.(Circulation. Heart failure, 2023-08) Keshvani, Neil; Subramanian, Vinayak; Wrobel, Christopher A; Solomon, Nicole; Alhanti, Brooke; Greene, Stephen J; DeVore, Adam D; Yancy, Clyde W; Allen, Larry A; Fonarow, Gregg C; Pandey, AmbarishBackground
Coverage for cardiac rehabilitation (CR) for patients with heart failure with reduced ejection fraction was expanded in 2014, but contemporary referral and participation rates remain unknown.Methods
Patients hospitalized for heart failure with reduced ejection fraction (≤35%) in the American Heart Association Get With The Guidelines-Heart Failure registry from 2010 to 2020 were included, and CR referral status was described as yes, no, or not captured. Temporal trends in CR referral were assessed in the overall cohort. Patient and hospital-level predictors of CR referral were assessed using multivariable-adjusted logistic regression models. Additionally, CR referral and proportional utilization of CR within 1-year of referral were evaluated among patients aged >65 years with available Medicare administrative claims data who were clinically stable for 6-weeks postdischarge. Finally, the association of CR referral with the risk of 1-year death and readmission was evaluated using multivariable-adjusted Cox models.Results
Of 69,441 patients with heart failure with reduced ejection fraction who were eligible for CR (median age 67 years; 33% women; 30% Black), 17,076 (24.6%) were referred to CR, and referral rates increased from 8.1% in 2010 to 24.1% in 2020 (Ptrend<0.001). Of 8310 patients with Medicare who remained clinically stable 6-weeks after discharge, the CR referral rate was 25.8%, and utilization of CR among referred patients was 4.1% (mean sessions attended: 6.7). Patients not referred were more likely to be older, of Black race, and with a higher burden of comorbidities. In adjusted analysis, eligible patients with heart failure with reduced ejection fraction who were referred to CR (versus not referred) had a lower risk of 1-year death (hazard ratio, 0.84 [95% CI, 0.70-1.00]; P=0.049) without significant differences in 1-year readmission.Conclusions
CR referral rates have increased from 2010 to 2020. However, only 1 in 4 patients are referred to CR. Among eligible patients who received CR referral, participation was low, with <1 of 20 participating in CR.Item Open Access Projected Clinical Benefits of Implementation of SGLT-2 Inhibitors Among Medicare Beneficiaries Hospitalized for Heart Failure.(Journal of cardiac failure, 2022-04) Vaduganathan, Muthiah; Greene, Stephen J; Zhang, Shuaiqi; Solomon, Nicole; Chiswell, Karen; Devore, Adam D; Butler, Javed; Heidenreich, Paul A; Huang, Joanna C; Kittleson, Michelle M; Joynt Maddox, Karen E; Mcdermott, James J; Owens, Anjali Tiku; Peterson, Pamela N; Solomon, Scott D; Vardeny, Orly; Yancy, Clyde W; Fonarow, Gregg CBackground
The sodium-glucose cotransporter-2 (SGLT-2) inhibitors form the latest pillar in the management of heart failure with reduced ejection fraction (HFrEF) and appear to be effective across a range of patient profiles. There is increasing interest in initiating SGLT-2 inhibitors during hospitalization, yet little is known about the putative benefits of this implementation strategy.Methods
We evaluated Medicare beneficiaries with HFrEF (≤ 40%) hospitalized at 228 sites in the Get With The Guidelines-Heart Failure (GWTG-HF) registry in 2016 who had linked claims data for ≥ 1 year postdischarge. We identified those eligible for dapagliflozin under the latest U.S. Food and Drug Administration label (excluding estimated glomerular filtration rates < 25 mL/min per 1.73 m2, dialysis and type 1 diabetes). We evaluated 1-year outcomes overall and among key subgroups (age ≥ 75 years, gender, race, hospital region, kidney function, diabetes status, triple therapy). We then projected the potential benefits of implementation of dapagliflozin based on the risk reductions observed in the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) trial.Results
Among 7523 patients hospitalized for HFrEF, 6576 (87%) would be candidates for dapagliflozin (mean age 79 ± 8 years, 39% women, 11% Black). Among eligible candidates, discharge use of β-blockers, ACEi/ARB, MRA, ARNI, and triple therapy (ACEi/ARB/ARNI+β-blocker+MRA) was recorded in 88%, 64%, 29%, 3%, and 20%, respectively. Among treatment-eligible patients, the 1-year incidence (95% CI) of mortality was 37% (36-38%) and of HF readmission was 33% (32-34%), and each exceeded 25% across all key subgroups. Among 1333 beneficiaries eligible for dapagliflozin who were already on triple therapy, the 1-year incidence of mortality was 26% (24%-29%) and the 1-year readmission due to HF was 30% (27%-32%). Applying the relative risk reductions observed in DAPA-HF, absolute risk reductions with complete implementation of dapagliflozin among treatment-eligible Medicare beneficiaries are projected to be 5% (1%-9%) for mortality and 9% (5%-12%) for HF readmission by 1 year. The projected number of Medicare beneficiaries who would need to be treated for 1 year to prevent 1 death is 19 (11-114), and 12 (8-21) would need to be treated to prevent 1 readmission due to HF.Conclusions
Medicare beneficiaries with HFrEF who are eligible for dapagliflozin after hospitalization due to HF, including those well-treated with other disease-modifying therapies, face high risks of mortality and HF readmission by 1 year. If the benefits of reductions in death and hospitalizations due to HF observed in clinical trials can be fully realized, the absolute benefits of implementation of SGLT-2 inhibitors among treatment-eligible candidates are anticipated to be substantial in this high-risk postdischarge setting.Item Open Access Racial and Ethnic Differences in Presentation and Outcomes for Patients Hospitalized With COVID-19: Findings From the American Heart Association's COVID-19 Cardiovascular Disease Registry.(Circulation, 2021-06) Rodriguez, Fatima; Solomon, Nicole; de Lemos, James A; Das, Sandeep R; Morrow, David A; Bradley, Steven M; Elkind, Mitchell SV; Williams, Joseph H; Holmes, DaJuanicia; Matsouaka, Roland A; Gupta, Divya; Gluckman, Ty J; Abdalla, Marwah; Albert, Michelle A; Yancy, Clyde W; Wang, Tracy YBackground
The coronavirus disease 2019 (COVID-19) pandemic has exposed longstanding racial and ethnic inequities in health risks and outcomes in the United States. We aimed to identify racial and ethnic differences in presentation and outcomes for patients hospitalized with COVID-19.Methods
The American Heart Association COVID-19 Cardiovascular Disease Registry is a retrospective observational registry capturing consecutive patients hospitalized with COVID-19. We present data on the first 7868 patients by race/ethnicity treated at 88 hospitals across the United States between January 17, 2020, and July 22, 2020. The primary outcome was in-hospital mortality. Secondary outcomes included major adverse cardiovascular events (death, myocardial infarction, stroke, heart failure) and COVID-19 cardiorespiratory ordinal severity score (worst to best: death, cardiac arrest, mechanical ventilation with mechanical circulatory support, mechanical ventilation with vasopressors/inotrope support, mechanical ventilation without hemodynamic support, and hospitalization alone. Multivariable logistic regression analyses were performed to assess the relationship between race/ethnicity and each outcome adjusting for differences in sociodemographic, clinical, and presentation features, and accounting for clustering by hospital.Results
Among 7868 patients hospitalized with COVID-19, 33.0% were Hispanic, 25.5% were non-Hispanic Black, 6.3% were Asian, and 35.2% were non-Hispanic White. Hispanic and Black patients were younger than non-Hispanic White and Asian patients and were more likely to be uninsured. Black patients had the highest prevalence of obesity, hypertension, and diabetes. Black patients also had the highest rates of mechanical ventilation (23.2%) and renal replacement therapy (6.6%) but the lowest rates of remdesivir use (6.1%). Overall mortality was 18.4% with 53% of all deaths occurring in Black and Hispanic patients. The adjusted odds ratios for mortality were 0.93 (95% CI, 0.76-1.14) for Black patients, 0.90 (95% CI, 0.73-1.11) for Hispanic patients, and 1.31 (95% CI, 0.96-1.80) for Asian patients compared with non-Hispanic White patients. The median odds ratio across hospitals was 1.99 (95% CI, 1.74-2.48). Results were similar for major adverse cardiovascular events. Asian patients had the highest COVID-19 cardiorespiratory severity at presentation (adjusted odds ratio, 1.48 [95% CI, 1.16-1.90]).Conclusions
Although in-hospital mortality and major adverse cardiovascular events did not differ by race/ethnicity after adjustment, Black and Hispanic patients bore a greater burden of mortality and morbidity because of their disproportionate representation among COVID-19 hospitalizations.Item Open Access Racial differences in the prevalence and outcomes of atrial fibrillation among patients hospitalized with heart failure.(J Am Heart Assoc, 2013-09-26) Thomas, Kevin L; Piccini, Jonathan P; Liang, Li; Fonarow, Gregg C; Yancy, Clyde W; Peterson, Eric D; Hernandez, Adrian F; Get With the Guidelines Steering Committee and HospitalsBACKGROUND: The intersection of heart failure (HF) and atrial fibrillation (AF) is common, but the burden of AF among black patients with HF is poorly characterized. We sought to determine the prevalence of AF, characteristics, in-hospital outcomes, and warfarin use associated with AF in patients hospitalized with HF as a function of race. METHODS AND RESULTS: We analyzed data on 135 494 hospitalizations from January 2006 through January 2012 at 276 hospitals participating in the American Heart Association's Get With The Guidelines HF Program. Multivariable logistic regression models using generalized estimating equations approach for risk-adjusted comparison of AF prevalence, in-hospital outcomes, and warfarin use. In this HF population, 53 389 (39.4%) had AF. Black patients had markedly less AF than white patients (20.8% versus 44.8%, P < 0.001). Adjusting for risk factors and hospital characteristics, black race was associated with significantly lower odds of AF (adjusted odds ratio 0.52, 95% CI 0.48 to 0.55, P < 0.0001). There were no racial differences in in-hospital mortality; however, black patients had a longer length of stay relative to white patients. Black patients compared with white patients with AF were less likely to be discharged on warfarin (adjusted odds ratio 0.76, 95% CI 0.69 to 0.85, P < 0.001). CONCLUSIONS: Despite having many risk factors for AF, black patients, relative to white patients hospitalized for HF, had a lower prevalence of AF and lower prescription of guideline-recommended warfarin therapy.Item Open Access Short- and long-term rehospitalization and mortality for heart failure in 4 racial/ethnic populations.(J Am Heart Assoc, 2014-10-16) Vivo, Rey P; Krim, Selim R; Liang, Li; Neely, Megan; Hernandez, Adrian F; Eapen, Zubin J; Peterson, Eric D; Bhatt, Deepak L; Heidenreich, Paul A; Yancy, Clyde W; Fonarow, Gregg CBACKGROUND: The degree to which outcomes following hospitalization for acute heart failure (HF) vary by racial and ethnic groups is poorly characterized. We sought to compare 30-day and 1-year rehospitalization and mortality rates for HF among 4 race/ethnic groups. METHODS AND RESULTS: Using the Get With The Guidelines-HF registry linked with Medicare data, we compared 30-day and 1-year outcomes between racial/ethnic groups by using a multivariable Cox proportional hazards model adjusting for clinical, hospital, and socioeconomic status characteristics. We analyzed 47 149 Medicare patients aged ≥65 years who had been discharged for HF between 2005 and 2011: there were 39 213 whites (83.2%), 4946 blacks (10.5%), 2347 Hispanics (5.0%), and 643 Asians/Pacific Islanders (1.4%). Relative to whites, blacks and Hispanics had higher 30-day and 1-year unadjusted readmission rates but lower 30-day and 1-year mortality; Asians had similar 30-day readmission rates but lower 1-year mortality. After risk adjustment, blacks had higher 30-day and 1-year CV readmission than whites but modestly lower short- and long-term mortality; Hispanics had higher 30-day and 1-year readmission rates and similar 1-year mortality than whites, while Asians had similar outcomes. When socioeconomic status data were added to the model, the majority of associations persisted, but the difference in 30-day and 1-year readmission rates between white and Hispanic patients became nonsignificant. CONCLUSIONS: Among Medicare patients hospitalized with HF, short- and long-term readmission rates and mortality differed among the 4 major racial/ethnic populations and persisted even after controlling for clinical, hospital, and socioeconomic status variables.Item Open Access The Association Between Beta-blocker and Renin-Angiotensin System Inhibitor Use After Heart Failure With Reduced Ejection Fraction Hospitalization and Outcomes in Older Patients.(Journal of cardiac failure, 2023-04) Gilstrap, Lauren; Solomon, Nicole; Chiswell, Karen; James O'Malley, A; Skinner, Jonathan S; Fonarow, Gregg C; Bhatt, Deepak L; Yancy, Clyde W; Devore, Adam DIntroduction
Beta-blockers (BB) and renin-angiotensin system inhibitors (RASi) are foundational for the treatment of heart failure with reduced ejection fraction (HFrEF). However, given the increased risk of side effects in older patients, uncertainty remains as to whether, on net, older patients benefit as much as the younger patients studied in trials.Methods and results
Using the Get With The Guidelines-Heart Failure registry linked with Medicare data, overlap propensity weighted Cox proportional hazard models were used to examine the association between BB and RASi use at hospital discharge and 30-day and 1-year outcomes among patients with HFrEF. Among the 48,711 patients (aged ≥65 years) hospitalized with HFrEF, there were significant associations between BB and/or RASi use at discharge and lower rates of 30-day and 1-year mortality, including those over age 85 (30-day hazard ratio 0.56, 95% confidence interval 0.45-0.70; 1-year hazard ratio 0.69, 95% confidence interval 0.61-0.78). In addition, the magnitude of benefit associated with BB and/or RASi use after discharge did not decrease with advancing age. Even among the oldest patients, those over age 85, with hypotension, renal insufficiency or frailty, BB and/or RASi use at discharge was still associated with lower 1-year mortality or readmission.Conclusions
Among older patients hospitalized with HFrEF, BB and/or RASi use at discharge is associated with lower rates of 30-day and 1-year mortality across all age groups and the magnitude of this benefit does not seem to decrease with advancing age. These data suggest that, absent a clinical contraindication, BB and RASi should be considered in all patients hospitalized with HFrEF before or at hospital discharge, regardless of age.
