Background: Loop diuretics are a primary therapy for the symptomatic treatment of heart failure (HF), but whether torsemide improves patient symptoms and quality of life better than furosemide remains unknown. As prespecified secondary end points, the TRANSFORM-HF trial (Torsemide Comparison With Furosemide for Management of Heart Failure) compared the effect of torsemide versus furosemide on patient-reported outcomes among patients with HF. Methods: TRANSFORM-HF was an open-label, pragmatic, randomized trial of 2859 patients hospitalized for HF (regardless of ejection fraction) across 60 hospitals in the United States. Patients were randomly assigned in a 1:1 ratio to a loop diuretic strategy of torsemide or furosemide with investigator-selected dosage. This report examined effects on prespecified secondary end points, which included Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS; assessed as adjusted mean difference in change from baseline; range, 0–100 with 100 indicating best health status; clinically important difference, ≥5 points) and Patient Health Questionnaire-2 (range, 0–6; score ≥3 supporting evaluation for depression) over 12 months. Results: Baseline data were available for 2787 (97.5%) patients for KCCQ-CSS and 2624 (91.8%) patients for Patient Health Questionnaire-2. Median (interquartile range) baseline KCCQ-CSS was 42 (27–60) in the torsemide group and 40 (24–59) in the furosemide group. At 12 months, there was no significant difference between torsemide and furosemide in change from baseline in KCCQ-CSS (adjusted mean difference, 0.06 [95% CI, –2.26 to 2.37]; P =0.96) or the proportion of patients with Patient Health Questionnaire-2 score ≥3 (15.1% versus 13.2%: P =0.34). Results for KCCQ-CSS were similar at 1 month (adjusted mean difference, 1.36 [95% CI, –0.64 to 3.36]; P =0.18) and 6-month follow-up (adjusted mean difference, –0.37 [95% CI, –2.52 to 1.78]; P =0.73), and across subgroups by ejection fraction phenotype, New York Heart Association class at randomization, and loop diuretic agent before hospitalization. Irrespective of baseline KCCQ-CSS tertile, there was no significant difference between torsemide and furosemide on change in KCCQ-CSS, all-cause mortality, or all-cause hospitalization. Conclusions: Among patients discharged after hospitalization for HF, a strategy of torsemide compared with furosemide did not improve symptoms or quality of life over 12 months. The effects of torsemide and furosemide on patient-reported outcomes were similar regardless of ejection fraction, previous loop diuretic use, and baseline health status.

Key Points: Question: Does torsemide reduce all-cause mortality compared with furosemide in patients with heart failure following hospitalization? Findings: In this randomized clinical trial of 2859 patients, 26.1% of patients randomized to torsemide and 26.2% randomized to furosemide died over a median follow-up of 17.4 months without a significant difference between groups. Meaning: Among patients discharged after hospitalization for heart failure, torsemide compared with furosemide did not result in a significant difference in all-cause mortality over 12 months; however, interpretation of these findings is limited by loss to follow-up and participant crossover and nonadherence. Importance: Although furosemide is the most commonly used loop diuretic in patients with heart failure, some studies suggest a potential benefit for torsemide. Objective: To determine whether torsemide results in decreased mortality compared with furosemide among patients hospitalized for heart failure. Design, Setting, and Participants: TRANSFORM-HF was an open-label, pragmatic randomized trial that recruited 2859 participants hospitalized with heart failure (regardless of ejection fraction) at 60 hospitals in the United States. Recruitment occurred from June 2018 through March 2022, with follow-up through 30 months for death and 12 months for hospitalizations. The final date for follow-up data collection was July 2022. Interventions: Loop diuretic strategy of torsemide (n = 1431) or furosemide (n = 1428) with investigator-selected dosage. Main Outcomes and Measures: The primary outcome was all-cause mortality in a time-to-event analysis. There were 5 secondary outcomes with all-cause mortality or all-cause hospitalization and total hospitalizations assessed over 12 months being highest in the hierarchy. The prespecified primary hypothesis was that torsemide would reduce all-cause mortality by 20% compared with furosemide. Results: TRANSFORM-HF randomized 2859 participants with a median age of 65 years (IQR, 56-75), 36.9% were women, and 33.9% were Black. Over a median follow-up of 17.4 months, a total of 113 patients (53 [3.7%] in the torsemide group and 60 [4.2%] in the furosemide group) withdrew consent from the trial prior to completion. Death occurred in 373 of 1431 patients (26.1%) in the torsemide group and 374 of 1428 patients (26.2%) in the furosemide group (hazard ratio, 1.02 [95% CI, 0.89-1.18]). Over 12 months following randomization, all-cause mortality or all-cause hospitalization occurred in 677 patients (47.3%) in the torsemide group and 704 patients (49.3%) in the furosemide group (hazard ratio, 0.92 [95% CI, 0.83-1.02]). There were 940 total hospitalizations among 536 participants in the torsemide group and 987 total hospitalizations among 577 participants in the furosemide group (rate ratio, 0.94 [95% CI, 0.84-1.07]). Results were similar across prespecified subgroups, including among patients with reduced, mildly reduced, or preserved ejection fraction. Conclusions and Relevance: Among patients discharged after hospitalization for heart failure, torsemide compared with furosemide did not result in a significant difference in all-cause mortality over 12 months. However, interpretation of these findings is limited by loss to follow-up and participant crossover and nonadherence. Trial Registration: ClinicalTrials.gov Identifier: NCT03296813 This clinical trial compares the efficacy of torsemide vs furosemide in decreasing the risk of death from any cause among patients hospitalized for heart failure (regardless of ejection fraction).

To evaluate the effects of achieved systolic blood pressure (SBP) during treatment on cardiovascular (CV) outcomes, the authors measured event rates of a composite primary endpoint (CV death or nonfatal myocardial infarction or stroke) at on-treatment SBPs of ≥140 mm Hg and the 10 mm Hg intervals of <140 mm Hg, <130 mm Hg, and <120 mm Hg in 6459 patients with diabetes (mean age, 67) and 4246 patients without diabetes (mean age, 69) from the Avoiding Cardiovascular Events in Combination Therapy in Patients Living With Systolic Hypertension (ACCOMPLISH) trial. In the diabetic cohort, the primary endpoint was 49% lower (P<.001) at <140 mm Hg than at ≥140 mm Hg, and the separate components of this endpoint were also significantly reduced. Further SBP reductions did not improve outcomes, and at <120 mm Hg they were no longer different (except for stroke) from ≥140 mm Hg. In contrast, in the nondiabetic cohort, the primary endpoint event rate fell steadily (although not significantly) through the decreasing SBP categories until it was reduced by 45% (P=.0413) at <120 mm Hg. Total stroke rates for both the diabetic (-56%, P=.0120) and nondiabetic (-68%, P=.0067) cohorts were lowest at <120 mm Hg, and adverse renal events (serum creatinine increase ≥50%) were significantly lowest in the range of 130 mm Hg to 139 mm Hg for both cohorts. Diabetic patients (<140 mm Hg or <130 mm Hg) and nondiabetic patients (<120 mm Hg) may require different SBP targets for optimal CV protection, although stroke and renal considerations should also influence the selection of blood pressure targets.

Background: The STICH Randomized Clinical Trial (Surgical Treatment for Ischemic Heart Failure) demonstrated that coronary artery bypass grafting (CABG) reduced all-cause mortality rates out to 10 years compared with medical therapy alone (MED) in patients with ischemic cardiomyopathy and reduced left ventricular function (ejection fraction ≤35%). We examined the economic implications of these results.Methods: We used a decision-analytic patient-level simulation model to estimate the lifetime costs and benefits of CABG and MED using patient-level resource use and clinical data collected in the STICH trial. Patient-level costs were calculated by applying externally derived US cost weights to resource use counts during trial follow-up. A 3% discount rate was applied to both future costs and benefits. The primary outcome was the incremental cost-effectiveness ratio assessed from the US health care sector perspective.Results: For the CABG arm, we estimated 6.53 quality-adjusted life-years (95% CI, 5.70-7.53) and a lifetime cost of $140 059 (95% CI, $106 401 to $180 992). For the MED arm, the corresponding estimates were 5.52 (95% CI, 5.06-6.09) quality-adjusted life-years and $74 894 lifetime cost (95% CI, $58 372 to $93 541). The incremental cost-effectiveness ratio for CABG compared with MED was $63 989 per quality-adjusted life-year gained. At a societal willingness-to-pay threshold of $100 000 per quality-adjusted life-year gained, CABG was found to be economically favorable compared with MED in 87% of microsimulations.Conclusions: In the STICH trial, in patients with ischemic cardiomyopathy and reduced left ventricular function, CABG was economically attractive relative to MED at current benchmarks for value in the United States.Registration: URL: https://www.Clinicaltrials: gov; Unique identifier: NCT00023595.

Background: Guidelines recommend that patients with low ejection fraction (EF) after myocardial infarction (MI) have their EF reassessed 40 days after MI for implantable cardioverter-defibrillator (ICD) candidacy. This study examines rates of EF reassessment and their association with 1-year ICD implantation in post-MI patients with low EF.Methods: We examined rates of postdischarge EF reassessment and ICD implantation among 10 289 Medicare-insured patients ≥65 years of age with an EF≤35% during the index MI admission from January 2007 through September 2010 in ACTION Registry-GWTG (Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With The Guidelines). Multivariable Cox models tested the association between time-dependent EF reassessment and 1-year ICD implantation, stratified by revascularization status during the index MI admission.Results: Among patients with EF ≤35% during the index MI admission, 66.8% (95% confidence interval [CI], 65.9-67.8) had EF reassessment within the next year. Revascularized patients were more likely to have EF reassessment (76.9% [95% CI, 75.8-78.0)] versus 53.7% [95% CI, 52.2-55.2]; P<0.001) and had shorter times to EF reassessment (median, 67 versus 84 days; P<0.001) than nonrevascularized patients. Among patients with EF reassessment, only 11% received an ICD within 1 year. Reassessment of EF was associated with a higher likelihood of ICD implantation for both revascularized (unadjusted, 12.1% versus 2.4%, P<0.001; adjusted hazard ratio, 10.6, 95% CI, 7.7-14.8) and nonrevascularized (unadjusted, 10.0% versus 1.7%, P<0.001; adjusted hazard ratio, 6.1, 95% CI, 4.1-9.2) patients.Conclusions: In US practice, EF reassessments are commonly performed among patients with MI with an initially reduced EF. Although 1-year EF reassessment is associated with increased likelihood of ICD implantation, 1-year ICD implantation rates remain very low even among patients with EF reassessment, regardless of revascularization status.

Background: Underrepresented racial and ethnic groups (UREGs) with HIV have a higher risk of cardiovascular disease (CVD) compared with the general population. Referral to a cardiovascular specialist improves CVD risk factor management in high-risk individuals. However, patient and provider factors impacting the likelihood of UREGs with HIV to have an encounter with a cardiologist are unknown., Methods: We evaluated a cohort of UREGs with HIV and borderline CVD risk (10-year risk ≥ 5% by the pooled cohort equations or ≥ 7.5% by Framingham risk score). Participants received HIV-related care from 2014-2020 at four academic medical centers in the United States (U.S.). Adjusted Cox proportional hazards regression was used to estimate the association of patient and provider characteristics with time to first ambulatory cardiology encounter., Results: A total of 2,039 people with HIV (PWH) and borderline CVD risk were identified. The median age was 45 years (IQR: 36-50); 52% were female; and 94% were Black. Of these participants, 283 (14%) had an ambulatory visit with a cardiologist (17% of women vs. 11% of men, p < .001). In fully adjusted models, older age, higher body mass index (BMI), atrial fibrillation, multimorbidity, urban residence, and no recent insurance were associated with a greater likelihood of an encounter with a cardiologist., Conclusion: In UREGs with HIV and borderline CVD risk, the strongest determinants of a cardiology encounter were diagnosed CVD, insurance type, and urban residence. Future research is needed to determine the extent to which these encounters impact CVD care practices and outcomes in this population., Trial Registration: ClinicalTrials.gov Identifier: NCT04025125., (© 2023.

Acute Heart failure (AHF) is among the most frequent causes of hospitalization in the United States, contributing to substantial health care costs, morbidity, and mortality. Inpatient initiation of guideline-directed medical therapy (GDMT) is recommended for patients with heart failure with reduced ejection fraction (HFrEF) to reduce the risk of cardiovascular death or HF hospitalization. However, underutilization of GDMT prior to discharge is pervasive, representing a valuable missed opportunity to optimize evidence-based care. The PRagmatic Trial Of Messaging to Providers about Treatment of Acute Heart Failure tests the effectiveness of an electronic health record embedded clinical decision support system that informs providers during hospital management about indicated but not yet prescribed GDMT for eligible AHF patients with HFrEF. PRagmatic Trial Of Messaging to Providers about Treatment of Acute Heart Failureis an open-label, multicenter, pragmatic randomized controlled trial of 1,012 patients hospitalized with HFrEF. Eligible patients randomized to the intervention group are exposed to a tailored best practice advisory embedded within the electronic health record that alerts providers to prescribe omitted GDMT. The primary outcome is an increase in the proportion of additional GDMT medication classes prescribed at the time of discharge compared to those in the usual care arm., Competing Interests: Disclosures JH, TO, JM are employees of AstraZeneca.

Background: Death ascertainment can be challenging for pragmatic clinical trials that limit site follow-up activities to usual clinical care., Methods and Results: We used blinded aggregate data from the ongoing ToRsemide comparison with furoSemide FOR Management of Heart Failure (TRANSFORM-HF) pragmatic clinical trial in patients with heart failure to evaluate the agreement between centralized call center death event identification and the United States National Death Index (NDI). Of 2284 total patients randomized through April 12, 2021, 1480 were randomized in 2018-2019 and 804 in 2020-2021. The call center identified 416 total death events (177 in 2018-2019 and 239 in 2020-2021). The NDI 2018-2019 final file identified 178 death events, 165 of which were also identified by the call center. The study's inter-rater reliability metric (Cohen's kappa coefficient, 0.920; 95% confidence interval, 0.889-0.951) demonstrates a high level of agreement. The time between a death event and its identification was less for the call center (median, 47 days; interquartile range, 11-103 days) than for the NDI (median, 270 days; interquartile range, 186-391 days)., Conclusions: There is substantial agreement between deaths identified by a centralized call center and the NDI. However, the time between a death event and its identification is significantly less for the call center., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Heart failure with reduced ejection fraction (HFrEF) is one of the most common chronic illnesses in the United States and carries significant risk of morbidity and mortality. Use of guideline-directed medical therapy (GDMT) for patients with HFrEF has been shown to dramatically improve outcomes, but adoption of these treatments remains generally low. Possible explanations for poor GDMT uptake include lack of knowledge about recommended management strategies and provider reluctance due to uncertainties regarding application of said guidelines to real-world practice. One way to overcome these barriers is by harnessing the electronic health record (EHR) to create patient-centered "best practice alerts" (BPAs) that can guide clinicians to prescribe appropriate medical therapies. If found to be effective, these low-cost interventions can be rapidly applied across large integrated healthcare systems. The PRagmatic Trial Of Messaging to Providers about Treatment of Heart Failure (PROMPT-HF) trial is a pragmatic, cluster randomized controlled trial designed to test the hypothesis that tailored and timely alerting of recommended GDMT in heart failure (HF) will result in greater adherence to guidelines when compared with usual care. PROMPT-HF has completed enrollment of 1,310 ambulatory patients with HFrEF cared for by 100 providers who were randomized to receive a BPA vs usual care. The BPA alerted providers to GDMT recommended for their patients and displayed current left ventricular ejection fraction (LVEF) along with the most recent blood pressure, heart rate, serum potassium and creatinine levels, and estimated glomerular filtration rate. It also linked to an order set customized to the patient that suggests medications within each GDMT class not already prescribed. Our goal is to examine whether tailored EHR-based alerting for outpatients with HFrEF will lead to higher rates of GDMT at 30 days post randomization when compared with usual care. Additionally, we are assessing clinical outcomes such as hospital readmissions and death between the alert versus usual care group.

Background: Whether the volume of coronavirus disease 2019 (COVID-19) hospitalizations is associated with outcomes has important implications for the organization of hospital care both during this pandemic and future novel and rapidly evolving high-volume conditions., Methods: We identified COVID-19 hospitalizations at US hospitals in the American Heart Association COVID-19 Cardiovascular Disease Registry with ≥10 cases between January and August 2020. We evaluated the association of COVID-19 hospitalization volume and weekly case growth indexed to hospital bed capacity, with hospital risk-standardized in-hospital case-fatality rate (rsCFR)., Results: There were 85 hospitals with 15,329 COVID-19 hospitalizations, with a median hospital case volume was 118 (interquartile range, 57, 252) and median growth rate of 2 cases per 100 beds per week but varied widely (interquartile range: 0.9 to 4.5). There was no significant association between overall hospital COVID-19 case volume and rsCFR (rho, 0.18, P = .09). However, hospitals with more rapid COVID-19 case-growth had higher rsCFR (rho, 0.22, P = 0.047), increasing across case growth quartiles (P trend = .03). Although there were no differences in medical treatments or intensive care unit therapies (mechanical ventilation, vasopressors), the highest case growth quartile had 4-fold higher odds of above median rsCFR, compared with the lowest quartile (odds ratio, 4.00; 1.15 to 13.8, P = .03)., Conclusions: An accelerated case growth trajectory is a marker of hospitals at risk of poor COVID-19 outcomes, identifying sites that may be targets for influx of additional resources or triage strategies. Early identification of such hospital signatures is essential as our health system prepares for future health challenges., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background Racial and ethnic disparities contribute to differences in access and outcomes for patients undergoing heart transplantation. We evaluated contemporary outcomes for heart transplantation stratified by race and ethnicity as well as the new 2018 allocation system. Methods and Results Adult heart recipients from 2011 to 2020 were identified in the United Network for Organ Sharing database and stratified into 3 groups: Black, Hispanic, and White. We analyzed recipient and donor characteristics, and outcomes. Among 32 353 patients (25% Black, 9% Hispanic, 66% White), Black and Hispanic patients were younger, more likely to be women and have diabetes mellitus or renal disease (all, P <0.05). Over the study period, the proportion of Black and Hispanic patients listed for transplant increased: 21.7% to 28.2% ( P =0.003) and 7.7% to 9.0% ( P =0.002), respectively. Compared with White patients, Black patients were less likely to undergo transplantation (adjusted hazard ratio [aHR], 0.87; CI, 0.84-0.90; P <0.001), but had a higher risk of post-transplant death (aHR, 1.14; CI, 1.04-1.24; P =0.004). There were no differences in transplantation likelihood or post-transplant mortality between Hispanic and White patients. Following the allocation system change, transplantation rates increased for all groups ( P <0.05). However, Black patients still had a lower likelihood of transplantation than White patients (aHR, 0.90; CI, 0.79-0.99; P =0.024). Conclusions Although the proportion of Black and Hispanic patients listed for cardiac transplantation have increased, significant disparities remain. Compared with White patients, Black patients were less likely to be transplanted, even with the new allocation system, and had a higher risk of post-transplantation death.

Individuals with established cardiovascular disease or a high burden of cardiovascular risk factors may be particularly vulnerable to develop complications from coronavirus disease 2019 (COVID-19). We conducted a prospective cohort study at a tertiary care center to identify risk factors for in-hospital mortality and major adverse cardiovascular events (MACE; a composite of myocardial infarction, stroke, new acute decompensated heart failure, venous thromboembolism, ventricular or atrial arrhythmia, pericardial effusion, or aborted cardiac arrest) among consecutively hospitalized adults with COVID-19, using multivariable binary logistic regression analysis. The study population comprised 586 COVID-19 positive patients. Median age was 67 (IQR: 55 to 80) years, 47.4% were female, and 36.7% had cardiovascular disease. Considering risk factors, 60.2% had hypertension, 39.8% diabetes, and 38.6% hyperlipidemia. Eighty-two individuals (14.0%) died in-hospital, and 135 (23.0%) experienced MACE. In a model adjusted for demographic characteristics, clinical presentation, and laboratory findings, age (odds ratio [OR], 1.28 per 5 years; 95% confidence interval [CI], 1.13 to 1.45), previous ventricular arrhythmia (OR, 18.97; 95% CI, 3.68 to 97.88), use of P2Y 12 -inhibitors (OR, 7.91; 95% CI, 1.64 to 38.17), higher C-reactive protein (OR, 1.81: 95% CI, 1.18 to 2.78), lower albumin (OR, 0.64: 95% CI, 0.47 to 0.86), and higher troponin T (OR, 1.84; 95% CI, 1.39 to 2.46) were associated with mortality (p <0.05). After adjustment for demographics, presentation, and laboratory findings, predictors of MACE were higher respiratory rates, altered mental status, and laboratory abnormalities, including higher troponin T (p <0.05). In conclusion, poor prognostic markers among hospitalized patients with COVID-19 included older age, pre-existing cardiovascular disease, respiratory failure, altered mental status, and higher troponin T concentrations., (Copyright © 2021 Elsevier Inc.

Background Several studies have shown improved outcomes in closed compared with open medical and surgical intensive care units. However, very little is known about the ideal organizational structure in the modern cardiac intensive care unit (CICU). Methods and Results We retrospectively reviewed consecutive unique admissions (n=3996) to our tertiary care CICU from September 2013 to October 2017. The aim of our study was to assess for differences in clinical outcomes between an open compared with a closed CICU. We used multivariable logistic regression adjusting for demographics, comorbidities, and severity of illness. The primary outcome was in-hospital mortality. We identified 2226 patients in the open unit and 1770 in the closed CICU. The unadjusted in-hospital mortality in the open compared with closed unit was 9.6% and 8.9%, respectively ( P =0.42). After multivariable adjustment, admission to the closed unit was associated with a lower in-hospital mortality (odds ratio [OR], 0.69; 95% CI: 0.53-0.90, P =0.007) and CICU mortality (OR, 0.70; 95% CI, 0.52-0.94, P =0.02). In subgroup analysis, admissions for cardiac arrest (OR, 0.42; 95% CI, 0.20-0.88, P =0.02) and respiratory insufficiency (OR, 0.43; 95% CI, 0.22-0.82, P =0.01) were also associated with a lower in-hospital mortality in the closed unit. We did not find a difference in CICU length of stay or total hospital charges ( P >0.05). Conclusions We found an association between lower in-hospital and CICU mortality after the transition to a closed CICU. These results may help guide the ongoing redesign in other tertiary care CICUs.

Background: Psychiatric comorbidities play a key role in patient selection for left ventricular assist devices (LVADs), but their impact on clinical outcomes is unknown., Objectives: The goal of this study was to examine the clinical impact of psychiatric illness on outcomes in patients receiving LVADs for end-stage heart failure (HF)., Methods: The study identified adults in the Interagency Registry for Mechanically Assisted Circulatory Support with psychiatric comorbidities (history of alcohol abuse, drug use, narcotic dependence, depression, and other major psychiatric diagnoses) receiving continuous-flow LVADs from 2008 to 2017. Demographic characteristics, survival, adverse events, and quality of life scores were compared for patients with and without each psychiatric comorbidity., Results: Over the study period, the prevalence of psychiatric comorbidities was low: alcohol abuse, n = 1,093 (5.5%); drug use, n = 1,077 (5.4%); narcotic dependence, n = 96 (0.5%); depression, n = 401 (2.0%); and other major psychiatric illnesses, n = 265 (1.4%). Narcotic dependence (adjusted hazard ratio: 1.9; 95% confidence interval: 1.2 to 3.0; p = 0.004) and other major psychiatric illnesses (adjusted hazard ratio: 1.4; 95% confidence interval: 1.0 to 1.9; p = 0.02) were associated with increased risk of mortality, whereas alcohol abuse, drug use, and depression were not. All comorbidities except narcotic dependence were associated with increased risk of rehospitalization and device-related infection (both p < 0.05). Kansas City Cardiomyopathy Questionnaire scores were lower from 6 to 24 months' post-implantation among patients with psychiatric comorbidities (p < 0.05)., Conclusions: Despite a low prevalence of psychiatric comorbidities among LVAD recipients, these conditions were associated with mortality risk, adverse events, and poorer quality of life. Further study is needed to understand how specific psychiatric conditions affect outcomes and how to best manage this vulnerable patient population., (Copyright © 2020. Published by Elsevier Inc.)

Background: Current guidelines recommend evaluation for underlying heart disease and reversible conditions for patients with new-onset heart failure (HF). There are limited data on contemporary testing for coronary artery disease (CAD) in patients with new-onset HF., Methods: We performed an observational cohort study using the Get With The Guidelines-Heart Failure registry linked to Medicare claims. All patients were aged ≥65 and hospitalized for new-onset HF from 2009 to 2015. We collected left ventricular ejection fraction (LVEF), prior HF history, and in-hospital CAD testing from the registry, as well as testing for CAD using claims from 90 days before to 90 days after index HF hospitalization., Results: Among 17 185 patients with new-onset HF, 6672 (39%) received testing for CAD, including 3997 (23%) during the index hospitalization. Testing for CAD differed by LVEF: 53% in HF with reduced EF (LVEF ≤40%), 42% in HF with borderline EF (LVEF, 41%-49%), and 31% in HF with preserved EF (LVEF ≥50%). After multivariable adjustment, patients who received testing for CAD, compared with those who did not, were younger and more likely to be male, have a smoking history, have hyperlipidemia, and have HF with reduced ejection fraction or HF with borderline ejection fraction (all P <0.05)., Conclusions: The majority of patients hospitalized for new-onset HF did not receive testing for CAD either during the hospitalization or in the 90 days before and after. The rates of testing for CAD were higher in patients with LVEF ≤40% though remained low. These data highlight an opportunity to improve care by identifying appropriate candidates for optimal CAD medical therapy and revascularization.

Improvement in survival in patients living with human immunodeficiency virus (PLHIV) has led to increased prevalence of cardiovascular disease. Whether HIV-associated immune dysfunction is associated with preclinical left ventricular (LV) dysfunction despite normal LV ejection fraction (LVEF) is unclear. Accordingly, we investigated the relation of immune status and LV function in PLHIV. Global longitudinal strain (GLS) analyses were performed retrospectively on all echocardiograms for PLHIV who had available HIV-1 RNA viral load, nadir, and proximal CD4 cell count data at Duke University Medical Center between 2001 and 2012. The relation between HIV-1 RNA viral load, nadir, and proximal CD4 count and GLS as a continuous dependent variable was assessed with unadjusted and adjusted linear regression. GLS was calculated for 253 PLHIV. Median GLS in our cohort was - 15.1% with interquartile range from (-16.7 to -13.6). All participants had an LVEF ≥50%. In adjusted analyses, proximal CD4 <500 cells/mm 3 and nadir CD4 <250 cells/mm 3 were significantly inversely correlated with GLS (p = 0.01 and p = 0.004, respectively). In PLHIV, patient with plasma HIV RNA <400 copies/ml at baseline had a trend toward significantly more negative values of GLS compared with those patients without viral suppression at baseline (p = 0.08). In conclusion, this study is the first to demonstrate such a high prevalence of abnormal GLS in PLHIV, and the first to identify that proximal and nadir CD4 cell count are independently associated with GLS despite normal LVEF., (Copyright © 2019 Elsevier Inc.

Background: We aimed to determine the association of MR severity and type with all-cause death in a large, real-world, clinical setting., Methods: We reviewed full echocardiography studies at Duke Echocardiography Laboratory (01/01/1995-12/31/2010), classifying MR based on valve morphology, presence of coronary artery disease, and left ventricular size and function. Survival was compared among patients stratified by MR type and baseline severity., Results: Of 93,007 qualifying patients, 32,137 (34.6%) had ≥mild MR. A total of 8094 (8.7%) had moderate/severe MR, which was primary myxomatous (14.1%), primary non-myxomatous (6.2%), secondary non-ischemic (17.0%), and secondary ischemic (49.4%). At 10 years, patients with primary myxomatous MR or MR due to indeterminate cause had survival rates of >60%; primary non-myxomatous, secondary ischemic, and non-ischemic MR had survival rates <50%. While mild (HR 1.06, 95% CI 1.03-1.09), moderate (HR 1.31, 95% CI 1.27-1.37), and severe (HR 1.55, 95% CI 1.46-1.65) MR were independently associated with all-cause death, the relationship of increasing MR severity with mortality varied across MR types (P ≤ .001 for interaction); the highest risk associated with worsening severity was seen in primary myxomatous MR followed by secondary ischemic MR and primary non-myxomatous MR., Conclusions: Although MR severity is independently associated with increased all-cause death risk for most forms of MR, the absolute mortality rates associated with worse MR severity are much higher for primary myxomatous, non-myxomatous, and secondary ischemic MR. The findings from this study support carefully defining MR by type and severity., (Published by Elsevier Inc.)

Objective: The aim of this work was to investigate determinants of structural myocardial abnormalities in persons living with human immunodeficiency virus (PLWH)., Methods and Results: We reviewed archived transthoracic echocardiograms (TTEs) performed on PLWH at Duke University Medical Center from 2001 to 2012. The primary outcomes were presence of left ventricular hypertrophy (LVH) or diastolic dysfunction (DD). TTEs for 498 human immunodeficiency virus-infected persons were reviewed (median age 44 years, 38% female, 72% black, 34% with hypertension, 15% with diabetes). Among those with usable images, LVH was detected in 174 of 473 persons (37%) according to LV mass criteria and in 99 of 322 persons (31%) according to American Society of Echocardiography LV mass index criteria. Definite DD was detected in 18 of 224 persons (8%). LVH was more common in PLWH with a CD4 count ≤ 200 cells/mm 3 proximal to TTE (adjusted OR 1.68, 95% CI 1.08-2.62), CD4 nadir ≤ 200 cells/mm 3 (adjusted OR 1.63, 95% CI 1.04-2.54) and less common in persons with viral suppression (OR 0.46, 95% CI 0.27-0.80). Lower CD4 nadirs (P = .002) and proximal CD4 counts (P = .002) were also associated with DD., Conclusions: Persons with a history of advanced human immunodeficiency virus-associated immune suppression are at higher risk of LVH and DD than infected persons with preserved immune function., (Copyright © 2018.

Aims: The incidence of and factors associated with sudden cardiac death (SCD) early after an acute heart failure (HF) hospital admission have not been well defined., Methods and Results: We assessed SCD and ventricular arrhythmias in the Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND-HF) trial, which included patients with acute HF with reduced or preserved ejection fraction. SCD, resuscitated SCD (RSCD), and sustained ventricular tachycardia/ventricular fibrillation (VT/VF) were adjudicated from randomization through 30 days and were combined into a composite endpoint. Baseline characteristics associated with this composite were determined by logistic regression. RSCD and VT/VF were included as time-dependent variables in a Cox model evaluating the association of these variables with 180-day all-cause mortality. Among 7011 patients, the 30-day all-cause mortality rate was 3.8%; SCD accounted for 17% of these deaths. The 30-day composite event rate was 1.8% (n = 121). Ten patients had more than one event with 30-day Kaplan-Meier event rates of 0.6% for SCD [95% confidence interval (CI) 0.5%-0.9%, n = 43], 0.4% for RSCD (95% CI 0.2%-0.5%, n = 24), and 0.9% for VT/VF (95% CI 0.7%-1.2%, n = 64). In the multivariable model, chronic obstructive pulmonary disease, history of VT, male sex, and longer QRS duration were associated with SCD, RSCD, or VT/VF. A RSCD or VT/VF event was associated with higher 180-day mortality (adjusted hazard ratio 6.6, 95% CI 4.8-9.1, P < 0.0001)., Conclusions: Approximately 2% of patients admitted for acute HF experienced SCD, RSCD, or VT/VF within 30 days of admission, and SCD accounted for 17% of all deaths within 30 days., (© 2017 The Authors.

There are limited data describing outcomes associated with an elevated heart rate in patients with heart failure with reduced ejection fraction (HFrEF) in routine clinical practice. We identified patients with HFrEF at Duke University Hospital undergoing echocardiograms and heart rate assessments without paced rhythms or atrial fibrillation. Outcomes (all-cause mortality or hospitalization and medical costs per day alive) were assessed using electronic medical records, hospital cost accounting data, and national death records. Patients were stratified by heart rate (<70 and ≥70 beats/min) and compared using generalized linear models specified with gamma error distributions and log links for costs and proportional hazard models for mortality/hospitalization. Of 722 eligible patients, 582 patients (81%) were treated with β blockers. The median heart rate was 81 beats/min (25th and 75th percentiles 69 to 96) and 527 patients (73%) had a heart rate ≥70 beats/min. After multivariate adjustment, a heart rate ≥70 beats/min was associated with increased 1-year all-cause mortality or hospitalization, hazard ratio 1.37 (95% CI 1.07 to 1.75) and increased medical costs per day alive, cost ratio 2.03 (95% CI 1.53 to 2.69). In conclusion, at a large tertiary care center, despite broad use of β blockers, a heart rate ≥70 beats/min was observed in 73% of patients with HFrEF and associated with worse 1-year outcomes and increased direct medical costs per day alive., (Copyright © 2016 Elsevier Inc.

Objectives: This study sought to test the hypothesis that end-systolic volume (ESV), as a marker of severity of left ventricular (LV) remodeling, influences the relationship between myocardial viability and survival in patients with coronary artery disease and LV systolic dysfunction., Background: Retrospective studies of ischemic LV dysfunction suggest that the severity of LV remodeling determines whether myocardial viability predicts improved survival with surgical compared with medical therapy, with coronary artery bypass grafting (CABG) only benefitting patients with viable myocardium who have smaller ESV. However, this has not been tested prospectively., Methods: Interactions of end-systolic volume index (ESVI), myocardial viability, and treatment with respect to survival were assessed in patients in the prospective randomized STICH (Comparison of Surgical and Medical Treatment for Congestive Heart Failure and Coronary Artery Disease) trial of CABG versus medical therapy who underwent viability assessment (n = 601; age 61 ± 9 years; ejection fraction ≤35%), with a median follow-up of 5.1 years. Median ESVI was 84 ml/m(2). Viability was assessed by single-photon emission computed tomography or dobutamine echocardiography using pre-specified criteria., Results: Mortality was highest among patients with larger ESVI and nonviability (p < 0.001), but no interaction was observed between ESVI, viability status, and treatment assignment (p = 0.491). Specifically, the effect of CABG versus medical therapy in patients with viable myocardium and ESVI ≤84 ml/m(2) (hazard ratio [HR]: 0.85; 95% confidence interval [CI]: 0.56 to 1.29) was no different than in patients with viability and ESVI >84 ml/m(2) (HR: 0.87; 95% CI: 0.57 to 1.31). Other ESVI thresholds yielded similar results, including ESVI ≤60 ml/m(2) (HR: 0.87; 95% CI: 0.44 to 1.74). ESVI and viability assessed as continuous rather than dichotomous variables yielded similar results (p = 0.562)., Conclusions: Among patients with ischemic cardiomyopathy, those with greater LV ESVI and no substantial viability had worse prognosis. However, the effect of CABG relative to medical therapy was not differentially influenced by the combination of these 2 factors. Lower ESVI did not identify patients in whom myocardial viability predicted better outcome with CABG relative to medical therapy.

Disparities in the quality of cardiovascular care provided to minorities have been well documented, but less is known about the use of quality improvement methods to eliminate these disparities. Measurement is also often impeded by a lack of reliable patient demographic data. The objective of this study was to assess the ability of hospitals with large minority populations to measure and improve the care rendered to Black and Hispanic patients. The Expecting Success: Excellence in Cardiac Care project utilized the standardized collection of self-reported patient race, ethnicity, and language data to generate stratified performance measures for cardiac care coupled with evidence-based practice tools in a national competitively selected sample of 10 hospitals with high cardiac volumes and largely minority patient populations. Main outcomes included changes in nationally recognized measures of acute myocardial infarction and heart failure quality of care and 2 composite measures, stratified by patient demographic characteristics. Quality improved significantly at 7 of the 10 hospitals as gauged by composite measures (p < .05), and improvements exceeded those observed nationally for all hospitals. Three of 10 hospitals found racial or ethnic disparities which were eliminated in the course of the project. Clinicians and institutions were able to join the standardized collection of self-reported patient demographic data to evidence-based measures and quality improvement tools to improve the care of minorities and eliminate disparities in care. This framework may be replicable to ensure equity in other clinical areas., (© 2012 National Association for Healthcare Quality.)

Background: Surgical ventricular reconstruction (SVR) is used in conjunction with coronary artery bypass graft surgery (CABG) to improve left ventricular function and clinical outcomes in selected patients with ischemic heart failure. The impact of SVR on quality of life (QOL) and medical costs is unknown., Methods: We compared CABG plus SVR with CABG alone in 1,000 patients with ischemic heart failure, an anterior wall scar, and a left ventricular ejection fraction or=92% complete. Cost data were collected on 196 (98%) of 200 patients enrolled in the United States., Results: Heart-failure-related QOL outcomes did not differ between the 2 treatment strategies out to 3 years (median Kansas City Cardiomyopathy Questionnaire scores for CABG alone and CABG plus SVR, respectively: baseline 53 versus 54, P = .53; 3 years 85 versus 84, P = .89). There were no treatment-related differences in other QOL measures. In the US patients, total index hospitalization costs averaged over $14,500 higher for CABG plus SVR (P = .004) due primarily to 4.2 extra postoperative, high-intensity care days in the hospital., Conclusions: Addition of SVR to CABG in patients with ischemic heart failure did not improve QOL but significantly increased health care costs.

Objectives: African Americans have a high incidence of heart failure (HF). Limited retrospective observational subgroup analyses of patients with left ventricular systolic dysfunction (LVSD) suggest marginal benefit of angiotensin-converting enzyme inhibitors in the prevention of HF hospitalizations or total mortality in African Americans., Background: Very few data exist concerning the effectiveness of angiotensin receptor blockers in this population., Methods: Baseline characteristics, treatments, and outcomes of patients from the U.S. (3,390 white and 340 African-American patients) in the VALIANT (VALsartan In Acute myocardial iNfarcTion) trial were compared. This trial included patients with an acute myocardial infarction (MI) after initial stabilization and documented LVSD and/or HF. Patients were randomly assigned to receive treatment with valsartan, captopril, or the combination; follow-up continued for up to 3 years (median 24.7 months)., Results: African Americans had more coronary risk factors, more markers of poor outcome after MI, and were less likely to be revascularized when compared with white patients. After adjusting for treatment assignment, baseline characteristics, and post-infarction parameters, no difference was found in the 3-year rate of all-cause mortality, cardiovascular mortality, rehospitalization for HF, recurrent MI, or stroke between the 2 groups., Conclusions: African Americans sustaining an acute MI with LVSD and/or HF had similar clinical outcomes compared with white Americans. Valsartan, captopril, or the combination had comparable effects on cardiovascular morbidity and mortality in African Americans and white Americans.

Background: Avoiding Cardiovascular events through COMbination therapy in Patients LIving with Systolic Hypertension (ACCOMPLISH) is an outcome study investigating aggressive antihypertensive combination treatment. It has achieved a larger fraction of overall patients with blood pressure (BP) <140/90 mmHg (73.3%) and diabetic patients <130/80 mmHg (43.3%) at 12 months of follow-up than any other large outcomes trial. We have analyzed baseline predictors of BPs and BP control at 12 months., Methods: Blinded baseline and 12-month BP was available in 10,173 patients of whom 6132 had diabetes. Univariate and multivariate logistic regression models were used for BP control at 12 months; simple and multiple regression models were used for absolute BP value at 12 months. A stepwise procedure was used to select significant predictors in multivariate analyses., Results: Mean (SD) BP fell from 145.5/80.2 mmHg (18.2/10.7 mmHg) at randomization to 132.7/74.7 mmHg (16/9.6 mmHg) at 12 months. The main baseline predictors of achieving BP control were region (USA), Caucasian race and taking lipid-lowering drugs. The predictors of uncontrolled BP were higher baseline systolic BP values, more previous antihypertensive medications, proteinuria and previous thiazide use., Conclusion: Patients in the USA, Caucasians and patients taking lipid-lowering therapy were most likely to reach BP targets with combination therapy. Strong predictors of uncontrolled hypertension were more severe hypertension, an established need for more antihypertensive drugs and target organ damage.

Background: Surgical ventricular restoration (SVR) is an operation that demonstrates promise to improve outcomes for patients with left ventricular dysfunction. Current use and operative outcomes of SVR have come from centers of expertise, and operative risks of SVR in community practice are unknown. We sought to characterize the performance of SVR nationally and describe the acute risks of mortality and major morbidity plus predictors of adverse outcomes., Methods: We identified patients undergoing an SVR procedure at US hospitals participating in the Society of Thoracic Surgeons (STS) National Cardiac Database from January 2002 to June 2004. Baseline characteristics, operative characteristics, clinical outcomes, and predictors of adverse procedural outcomes were analyzed., Results: There were 731 patients who underwent SVR at 141 of STS's 576 hospitals, and 20 centers performed 10 SVR procedures or more. The operative mortality was 9.3%; reoperation in 14.1%, stroke in 3.3%, renal failure in 8.1%, and prolonged ventilation in 21.5%. Combined death or major complications occurred in 33.5%. Major predictors of this combined end point were age, female sex, creatinine > or = 2 mg/dL, insulin-dependent diabetes, myocardial infarction within 1 week, history of congestive heart failure, 3-vessel coronary disease, severe mitral insufficiency, and status of surgery., Conclusion: This study provides a first look at use and outcomes of SVR in a national sample. Although a quarter of STS sites are performing SVR, most have limited experience and perioperative events are somewhat higher than prior selected series. Further studies of SVR are needed to improve patient selection and procedural performance.

Previous studies have shown that blacks have worse long-term outcomes than whites who have systolic heart failure. The reasons for these racial differences remain unclear. We investigated the effect of race and etiology of heart failure on outcomes of patients who had left ventricular (LV) systolic dysfunction. We studied records of 1,977 patients (27% black) who underwent cardiac catheterization who had New York Heart Association class II to IV symptoms and a LV ejection fraction <40%. Adjusted Cox's proportional hazards regression models were examined for the end points of mortality, rehospitalization, and a composite of the 2. Black versus white patients were younger (median age 56 vs 63 years, p <0.01), more often were women (49% vs 33%, p <0.01), had diabetes (37% vs 31%, p = 0.02), and hypertension (75% vs 56%, p <0.01). Black patients were less likely to have significant coronary artery disease by angiography (41% vs 69%, p <0.01). Race was not an independent predictor of mortality (hazard ratio 1.09, 95% confidence interval 0.93 to 1.28, p = 0.27). After adjusted survival curves were stratified by race and etiology, the estimates indicated that among those patients who had nonischemic LV dysfunction, blacks appeared to have worse survival than whites. Thus, we found no racial differences in the long-term mortality risk of patients who had symptomatic LV systolic dysfunction. In conclusion, after stratifying by ischemic and nonischemic etiologies, we found decreased survival in blacks who had a nonischemic etiology compared with whites. There were no racial differences in rehospitalization between patients who had ischemic LV systolic dysfunction and those who did not.
