RESUMEN

BACKGROUND: Remote monitoring of pulmonary artery (PA) pressures and serial N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurements guide heart failure (HF) treatment, but their association has yet to be described. METHODS AND RESULTS: In the Empagliflozin Evaluation by Measuring the Impact on Hemodynamics in Patients with Heart Failure (EMBRACE-HF) trial, patients with HF and a remote PA pressure monitoring device were randomized to empagliflozin vs placebo. PA diastolic pressures (PADP) and NT-proBNP levels were obtained at baseline and 6 and 12 weeks. We used linear mixed models to examine the association between change in PADP and change in NT-proBNP, adjusting for baseline covariates. Of 62 patients, the mean patient age was 66.2 years, and 63% were male. The mean baseline PADP was 21.8 ± 6.4 mm Hg, and the mean NT-proBNP was 1844.6 ± 2767.7 pg/mL. The mean change between baseline and averaged 6- and 12-week PADP was -0.4 ± 3.1 mm Hg, and the mean change between baseline and averaged 6- and 12-week NT-proBNP was -81.5 ± 878.6 pg/mL. In adjusted analyses, every 2-mm Hg decrease in PADP was associated with an NT-proBNP reduction of 108.9 pg/mL (95% confidence interval -4.3 to 222.0, P = .06). CONCLUSIONS: We observed that short-term decreases in ambulatory PADP seem to be associated with decreases in NT-proBNP. This finding may provide additional clinical context when tailoring treatment for patients with HF.

RESUMEN

PURPOSE OF REVIEW: The following review is intended to provide a summary of contemporary cardiogenic shock (CS) profiling and diagnostic strategies, including biomarker and hemodynamic-based (invasive and noninvasive) monitoring, discuss clinical differences in presentation and trajectory between acute myocardial infarction (AMI)-CS and heart failure (HF)-CS, describe transitions to native heart recovery and heart replacement therapies with a focus on tailored management and emerging real-world data, and emphasize trends in team-based initiatives and interventions for cardiogenic shock including the integration of protocol-driven care. RECENT FINDINGS: This document provides a broad overview of contemporary scientific consensus statements as well as data derived from randomized controlled clinical trials and observational registry working groups focused on cardiogenic shock management. SUMMARY: This review highlights the increasingly important role of pulmonary artery catheterization in AMI-CS and HF-CS cardiogenic shock and advocates for routine application of algorithmic approaches with interdisciplinary care pathways. Cardiogenic shock algorithms facilitate the integration of clinical, hemodynamic, and imaging data to determine the most appropriate patient hemodynamic support platform to achieve adequate organ perfusion and decongestion.

RESUMEN

Patients with heart failure and preserved ejection fraction (HFpEF) have a high burden of symptoms and functional limitations, and have a poor quality of life. By targeting cardiometabolic abmormalities, sodium glucose cotransporter 2 (SGLT2) inhibitors may improve these impairments. In this multicenter, randomized trial of patients with HFpEF (NCT03030235), we evaluated whether the SGLT2 inhibitor dapagliflozin improves the primary endpoint of Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CS), a measure of heart failure-related health status, at 12 weeks after treatment initiation. Secondary endpoints included the 6-minute walk test (6MWT), KCCQ Overall Summary Score (KCCQ-OS), clinically meaningful changes in KCCQ-CS and -OS, and changes in weight, natriuretic peptides, glycated hemoglobin and systolic blood pressure. In total, 324 patients were randomized to dapagliflozin or placebo. Dapagliflozin improved KCCQ-CS (effect size, 5.8 points (95% confidence interval (CI) 2.3-9.2, P = 0.001), meeting the predefined primary endpoint, due to improvements in both KCCQ total symptom score (KCCQ-TS) (5.8 points (95% CI 2.0-9.6, P = 0.003)) and physical limitations scores (5.3 points (95% CI 0.7-10.0, P = 0.026)). Dapagliflozin also improved 6MWT (mean effect size of 20.1 m (95% CI 5.6-34.7, P = 0.007)), KCCQ-OS (4.5 points (95% CI 1.1-7.8, P = 0.009)), proportion of participants with 5-point or greater improvements in KCCQ-OS (odds ratio (OR) = 1.73 (95% CI 1.05-2.85, P = 0.03)) and reduced weight (mean effect size, 0.72 kg (95% CI 0.01-1.42, P = 0.046)). There were no significant differences in other secondary endpoints. Adverse events were similar between dapagliflozin and placebo (44 (27.2%) versus 38 (23.5%) patients, respectively). These results indicate that 12 weeks of dapagliflozin treatment significantly improved patient-reported symptoms, physical limitations and exercise function and was well tolerated in chronic HFpEF.

RESUMEN

AIMS: Improving the health status (symptoms, function, and quality of life) of patients with heart failure with reduced ejection fraction (HFrEF) is a primary treatment goal. Angiotensin receptor neprilysin inhibitors (ARNI) improve short-term health status in clinical practice, but the sustainability of these improvements is unknown. METHODS AND RESULTS: In CHAMP-HF, a multicentre observational study of outpatients with HFrEF, patients initiated on ARNI were propensity score matched 1:2 to patients not using ARNI with Cox regression modelling time to ARNI initiation, adjusted for sociodemographic and clinical variables, medical history, medications, and baseline Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. Repeated measures models for the overall KCCQ score and each domain compared the health status trajectories of patients initiated on ARNI vs. not. Among 3930 participants, 746 (19.0%) began ARNI, of whom 576 were matched to 1152 non-ARNI patients. Prior to matching, participants initiated on ARNI were younger, non-Hispanic, had lower EFs, more commonly had a history of ventricular arrhythmia, were less likely to be taking an ACEI/ARB, and more likely to be treated with beta-blockers and mineralocorticoid receptor antagonists. There were no differences after matching. In the matched cohort, participants initiated on ARNI experienced improved health status by 3 months that persisted through 12 months [KCCQ Overall Summary Score (OSS) = 73.4 vs. 70.8; P < 0.001], with the largest benefit observed in the KCCQ Quality of Life domain (68.7 vs. 64.7; P < 0.001). Similar health status benefits were noted through 18 months (KCCQ-OSS = 73.9 vs. 71.3; P < 0.001). A responder analysis showed that 12 patients would need to be initiated on ARNI for one to experience at least a large improvement (≥10 points) in health status benefit at 12 months. CONCLUSIONS: In outpatient practice, ARNI therapy was associated with improved health status by 3 months and continued to 18 months after initiating therapy.

RESUMEN

Sodium-glucose cotransporter-2 (SGLT2) inhibitors have been shown to reduce the risk of cardiovascular death or worsening heart failure (HF), and improve symptom burden, physical function and quality of life in patients with HF and reduced ejection fraction. The mechanisms of the HF benefits of SGLT2 inhibitors, however, remain unclear. In this substudy of the DEFINE-HF trial, patients randomized to dapagliflozin or placebo had lung fluid volumes (LFVs) measured by remote dieletric sensing at baseline and after 12 weeks of therapy. A significantly greater proportion of dapagliflozin-treated patients (as compared with placebo) experienced improvement in LFVs and fewer dapagliflozin-treated patients had no change or deterioration in LFVs after 12 weeks of treatment. To our knowledge, this is the first study to suggest a direct effect of dapagliflozin (or any SGLT2 inhibitor) on more effective "decongestion", contributing in a meaningful way to the ongoing debate regarding the mechanisms of SGLT2 inhibitor HF benefits.

RESUMEN

AIMS: The aim of our study was to investigate heterogeneity of health status treatment response of sacubitril/valsartan in patients with heart failure with reduced ejection fraction (HFrEF). METHODS AND RESULTS: We leveraged data from CHAMP-HF, an observational registry of 140 US clinics and 5026 outpatients with chronic HFrEF, where health status was serially assessed using the Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 Overall Summary Scale (range from 0 to 100; ≥20-point improvement is a very large improvement). In 334 patients newly initiated on sacubitril/valsartan, we used hierarchical multivariable logistic regression (13 patient-level characteristics as well as baseline KCCQ-12 score) to calculate the odds ratio (OR) of any characteristic being associated with a very large health status improvement. A total of 104/334 (31.1%) of patients achieved the primary endpoint, where only worse baseline health status [KCCQ-12 score of 0-60 points had an OR = 0.86/5-point higher score (CI 0.79, 0.93)], and those with a KCCQ-12 score of 60-80 points had an OR = 0.61/5-point higher score (0.45-0.82), which was associated with a very large benefit. No other patient characteristic was associated with a very large health status improvement (P > 0.05). CONCLUSIONS: We found that, after initiation of sacubitril/valsartan, only worse baseline health status was associated with very large health status improvement. Accordingly, a trial of therapy-particularly in those with worse symptoms, function, and quality of life-and assessing treatment response are likely to be the best prospective strategy.

RESUMEN

Myocardial infarction with no obstructive coronary atherosclerosis (MINOCA) is a distinct clinical syndrome characterized by evidence of myocardial infarction with normal or near-normal coronary arteries on angiography (stenosis severity < 50%). Coronary artery spasm, as seen in "variant angina," usually occurs at a localized segment of an epicardial artery. Here, we present a case of a 58-year-old male who had norepinephrine-induced coronary vasospasm which resulted in ST elevation myocardial infarction on two consecutive admissions.

RESUMEN

BACKGROUND: Outcome trials in patients with type 2 diabetes mellitus have demonstrated reduced hospitalizations for heart failure (HF) with sodium-glucose co-transporter-2 inhibitors. However, few of these patients had HF, and those that did were not well-characterized. Thus, the effects of sodium-glucose co-transporter-2 inhibitors in patients with established HF with reduced ejection fraction, including those with and without type 2 diabetes mellitus, remain unknown. METHODS: DEFINE-HF (Dapagliflozin Effects on Biomarkers, Symptoms and Functional Status in Patients with HF with Reduced Ejection Fraction) was an investigator-initiated, multi-center, randomized controlled trial of HF patients with left ventricular ejection fraction ≤40%, New York Heart Association (NYHA) class II-III, estimated glomerular filtration rate ≥30 mL/min/1.73m2, and elevated natriuretic peptides. In total, 263 patients were randomized to dapagliflozin 10 mg daily or placebo for 12 weeks. Dual primary outcomes were (1) mean NT-proBNP (N-terminal pro b-type natriuretic peptide) and (2) proportion of patients with ≥5-point increase in HF disease-specific health status on the Kansas City Cardiomyopathy Questionnaire overall summary score, or a ≥20% decrease in NT-proBNP. RESULTS: Patient characteristics reflected stable, chronic HF with reduced ejection fraction with high use of optimal medical therapy. There was no significant difference in average 6- and 12-week adjusted NT-proBNP with dapagliflozin versus placebo (1133 pg/dL (95% CI 1036-1238) vs 1191 pg/dL (95% CI 1089-1304), P=0.43). For the second dual-primary outcome of a meaningful improvement in Kansas City Cardiomyopathy Questionnaire overall summary score or NT-proBNP, 61.5% of dapagliflozin-treated patients met this end point versus 50.4% with placebo (adjusted OR 1.8, 95% CI 1.03-3.06, nominal P=0.039). This was attributable to both higher proportions of patients with ≥5-point improvement in Kansas City Cardiomyopathy Questionnaire overall summary score (42.9 vs 32.5%, adjusted OR 1.73, 95% CI 0.98-3.05), and ≥20% reduction in NT-proBNP (44.0 vs 29.4%, adjusted OR 1.9, 95% CI 1.1-3.3) by 12 weeks. Results were consistent among patients with or without type 2 diabetes mellitus, and other prespecified subgroups (all P values for interaction=NS). CONCLUSIONS: In patients with heart failure and reduced ejection fraction, use of dapagliflozin over 12 weeks did not affect mean NT-proBNP but increased the proportion of patients experiencing clinically meaningful improvements in HF-related health status or natriuretic peptides. Benefits of dapagliflozin on clinically meaningful HF measures appear to extend to patients without type 2 diabetes mellitus. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov.

RESUMEN

OBJECTIVES: This study sought to describe the short-term health status benefits of angiotensin-neprilysin inhibitor (ARNI) therapy in patients with heart failure and reduced ejection fraction (HFrEF). BACKGROUND: Although therapy with sacubitril/valsartan, a neprilysin inhibitor, improved patients' health status (compared with enalapril) at 8 months in the PARADIGM-HF (Prospective Comparison of ARNI with ACE inhibitor to Determine Impact on Global Mortality and Morbidity in Heart Failure) study, the early impact of ARNI on patients' symptoms, functions, and quality of life is unknown. METHODS: Health status was assessed by using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ) in 3,918 outpatients with HFrEF and left ventricular ejection fraction ≤40% across 140 U.S. centers in the CHAMP-HF (Change the Management of Patients with Heart Failure) registry. ARNI therapy was initiated in 508 patients who were matched 1:2 to 1,016 patients who were not initiated on ARNI (no-ARNI), using a nonparsimonious time-dependent propensity score (6 sociodemographic factors, 23 clinical characteristics), prior KCCQ overall summary (KCCQ-OS) score, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker status. RESULTS: Multivariate linear regression demonstrated a greater mean improvement in KCCQ-OS in patients initiated on ARNI therapy (5.3 ± 19 vs. 2.5 ± 17.4, respectively; p < 0.001) over a median (interquartile range [IQR]) of 57 (32 to 104) days. The proportions of ARNI versus no-ARNI groups with ≥10-point (large) and ≥20-point (very large) improvements in KCCQ-OS were 32.7% versus 26.9%, respectively, and 20.5% versus 12.1%, respectively, consistent with numbers needed to treat of 18 and 12, respectively. CONCLUSIONS: In routine clinical care, ARNI therapy was associated with early improvements in health status, with 20% experiencing a very large health status benefit compared with 12% who were not started on ARNI therapy. These findings support the use of ARNI to improve patients' symptoms, functions, and quality of life.

RESUMEN

OBJECTIVES: The aim of this study was to use a multicenter, observational outpatient registry of patients with heart failure with reduced ejection fraction (HFrEF) to describe the association between changes in patients' medications with changes in health status. BACKGROUND: Alleviating symptoms and improving function and quality of life for patients with HFrEF are primary treatment goals and potential indicators of quality. Whether titrating medications in routine clinical care improves patients' health status is unknown. METHODS: The association of any change in HFrEF medications with 3-month change in health status, as measured using the 12-item Kansas City Cardiomyopathy Questionnaire Overall Summary Scale, was determined in unadjusted and multivariate-adjusted (25 clinical characteristics, baseline health status) models using hierarchical linear regression. RESULTS: Among 3,313 outpatients with HFrEF from 140 centers, 21.9% had medication changes. Three months later, 23.7% and 46.4% had clinically meaningfully worse (≥5-point decrease) and improved (≥5-point increase) Kansas City Cardiomyopathy Questionnaire Overall Summary Scale scores. The 3-month median change in Kansas City Cardiomyopathy Questionnaire Overall Summary Scale score for patients whose HFrEF medications were changed was significantly larger (7.3 points; interquartile range: -3.1 to 20.8 points) than in patients whose medications were not changed (3.1 points; interquartile range: -4.7 to 12.5 points) (adjusted difference 3.0 points; 95% confidence interval: 1.4 to 4.6 points; p < 0.001). Among patients whose medications were adjusted, 26% had very large clinical improvement (≥20 points) compared with 14% whose regimens were not changed. CONCLUSIONS: In routine care of patients with HFrEF, changes in HFrEF medications were associated with significant improvements in patients' health status, suggesting that health status-based performance measures can quantify the benefits of titrating medicines in patients with HFrEF.

RESUMEN

OBJECTIVES: This study sought to determine the rate of use of target doses of foundational guideline-directed medical therapy (GDMT) in a contemporary cohort of patients with heart failure with reduced ejection fraction (HFrEF) across systolic blood pressure (SBP) categories. BACKGROUND: Patients with HFrEF are infrequently titrated to recommended doses of GDMT. The relationship between SBP and achieving GDMT target doses is not well studied. METHODS: Patients enrolled in the CHAMP-HF (Change the Management of Patients With Heart Failure) registry without documented intolerance to angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitors (ARNIs), and beta blockers (BBs) were assessed at enrollment. We estimated the proportion receiving target doses (% of target dose [95% confidence interval (CI)]) based on the most recent American College of Cardiology/American Heart Association/Heart Failure Society of America heart failure guidelines at baseline in all patients, and by SBP category (≥110 vs. <110 mm Hg). RESULTS: Of the 3,095 patients eligible for analysis, 2,421 (78.2%) had SBP ≥110 mm Hg. The proportion of patients receiving target doses were 18.7% (95% CI: 17.3% to 20.0%; BB), 10.8% (95% CI: 9.7% to 11.9%; ACEI/ARB), and 2.0% (95% CI: 1.5% to 2.5%; ARNI). Among those with SBP <110 mm Hg (n = 674), 17.5% (95% CI: 14.6% to 20.4%; BB), 6.2% (95% CI: 4.4% to 8.1%; ACEI/ARB), and 1.8% (95% CI: 0.8% to 2.8%; ARNI) were receiving target doses. Among those with SBP ≥110 mm Hg (n = 2,421), 19.0% (95% CI: 17.4% to 20.6%; BB), 12.1% (95% CI: 10.8% to 13.4%; ACEI/ARB), and 2.0% (95% CI: 1.5% to 2.6%; ARNI) were receiving target doses. CONCLUSIONS: In a large, contemporary registry of outpatients with chronic HFrEF eligible for treatment with BBs and ACEI/ARB/ARNI, <20% of patients were receiving target doses, even among those with SBP ≥110 mm Hg.

RESUMEN

OBJECTIVES: This study sought to describe the association between chronic total occlusion (CTO) revascularization (CTO percutaneous coronary intervention [PCI]) and health status in patients with and without cardiomyopathy. BACKGROUND: Prior PCI trials for cardiomyopathy have excluded CTO patients. Whether patients with reduced left ventricular ejection fraction (LVEF) receive similar health status benefit from CTO-PCI compared with patients with normal LVEF is unclear. METHODS: We assessed health status change, using the Seattle Angina Questionnaire (SAQ) Summary, SAQ Angina Frequency, and Rose Dyspnea Scale scores, among patients undergoing successful CTO PCI in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion) Registry. Participants were classified by LVEF (normal, ≥50%; mild-moderate, 30% to 49%; and severe, <30%), with higher SAQ and lower Rose Dyspnea Scale scores indicating better health status. Differences in 1-year outcomes were compared using hierarchical multivariable regression. RESULTS: Of 762 patients, 506 (66.4%), 193 (25.3%), and 63 (8.3%) had normal, mild-moderate, and severely reduced LVEF. SAQ Summary score improvements were observed in each group (27.1 ± 20.4, 26.7 ± 21.2, and 20.3 ± 18.1, respectively). Compared with patients with LVEF ≥50%, those with LVEF <30% had less improvement in SAQ Summary Score (-5.2 points; 95% confidence interval: -9.0 to -1.5; p = 0.01) and Rose Dyspnea Scale (+0.5 points; 95% confidence interval: 0.1 to 0.8; p = 0.01), with no difference in odds of angina (odds ratio: 1.3; 95% confidence interval: 0.6 to 3.0; p = 0.48). Health status improvement was similar between patients with LVEF ≥50% and LVEF 30% to 49%. CONCLUSIONS: Although health status improvement was less in patients with severely reduced LVEF compared with those with normal LVEF, each group experienced large health status improvements after CTO-PCI.

RESUMEN

BACKGROUND: The ACC/AHA cholesterol guidelines recommend patients with peripheral artery disease (PAD) be treated with a moderate to high-intensity statin. The extent to which patients with new or worsening PAD symptoms are offered guideline therapy is unknown. HYPOTHESIS: There is significant variability in rate of guideline-directed statin intensification across clinical practices. METHODS: In the PORTRAIT registry, patterns of statin therapy were assessed in 1144 patients at 16 PAD specialty clinics between June 2011 and December 2015 before and after an evaluation for new or worsening claudication symptoms. We documented whether patients were treated with a guideline statin as well as the incidence of statin intensification. Statin intensification was defined as transitioning from no statin or low-intensity statin to moderate or high-intensity statin treatment. Patient factors associated with intensification were examined. Site and provider-level variation in intensification was summarized using an adjusted median odds ratio (aMOR). RESULTS: Among 1144 patients, 810 (70.8%) were initially on guideline therapy compared to 334 (29.2%) that were not. In the latter, 103 (30.8%) received intensification following evaluation. Patients with typical symptoms displayed greater odds of intensification (OR 3.74; 95% CI: 1.23-11.41) while older patients had lower odds of intensification (OR 0.60/decade; 95% CI: 0.41-0.88). Site variability for statin intensification was observed across sites (aMOR = 3.15; 95% CI 1.22-9.60, [P = 0.02]) but not providers (aMOR = 1.89; 95% CI 1.00-3.90, [P = 0.14]). CONCLUSIONS: Most patients evaluated at a PAD specialty clinic for new or worsening claudication symptoms arrived on guideline statin therapy. Only 31% not receiving appropriate therapy underwent statin intensification. These findings highlight an important opportunity to optimize medical therapy for patients with PAD.

RESUMEN

OBJECTIVES: This study sought to evaluate and contribute to the limited data on U.S. hospital practice patterns with respect to respiratory vaccination in patients hospitalized with heart failure (HF). BACKGROUND: Respiratory infection is a major driver of morbidity in patients with HF, and many influenza and pneumococcal infections may be prevented by vaccination. METHODS: This study evaluated patients hospitalized at centers participating in the Get With The Guidelines-HF (GWTG-HF) registry from October 2012 to March 2017. The proportion of patients receiving vaccination was described for influenza and pneumococcal vaccination, respectively. The association of hospital-level vaccination rates with individual GWTG-HF performance measures and defect-free care was evaluated using multivariable modeling. RESULTS: This study evaluated 313,761 patients discharged from 392 hospitals during the study period. The proportion of patients receiving influenza vaccination was 68% overall and declined from 70% in 2012 to 2013 to 66% in 2016 to 2017 (p < 0.001), although this was not statistically significant after adjustment (odds ratio: 1.05 per flu season; 95% confidence interval [CI]: 0.94 to 1.18). The proportion of patients receiving pneumococcal vaccination was 66% overall and decreased over the study period from 71% in 2013 to 60% in 2016 (p < 0.001), remaining significant after adjustment (odds ratio: 0.75 per calendar year; 95% CI: 0.67 to 0.84). Hospitals with higher vaccination rates were more likely to discharge patients with higher performance on defect-free care and individual GWTG-HF performance measures (p < 0.001). In a subset of patients with linked Medicare claims, vaccinated patients had similar rates of 1-year all-cause mortality (adjusted hazard ratio: 0.96 [95% CI: 0.89 to 1.03] for influenza vaccination; adjusted hazard ratio: 0.95 [95% CI: 0.89 to 1.01] for pneumococcal vaccination) compared with those not vaccinated. CONCLUSIONS: Nearly 1 in 3 patients hospitalized with HF at participating hospitals were not vaccinated for influenza or pneumococcal pneumonia, and vaccination rates did not improve from 2012 to 2017. Hospitals that exhibited higher vaccination rates performed well with respect to other HF quality of care measures. Vaccination status was not associated with differences in clinical outcomes. Further randomized controlled data are needed to assess the relationship between vaccination and outcomes.

RESUMEN

OBJECTIVES: This study sought to describe the health status of outpatients with heart failure and reduced ejection fraction (HFrEF) by sex, race/ethnicity, and socioeconomic status (SES). BACKGROUND: Although a primary goal in treating patients with HFrEF is to optimize health status, whether disparities by sex, race/ethnicity, and SES exist is unknown. METHODS: In the CHAMP-HF (Change the Management of Patients with Heart Failure) registry, the associations among sex, race, and SES and health status, as measured by the Kansas City Cardiomyopathy Questionnaire-overall summary (KCCQ-os) score (range 0 to 100; higher scores indicate better health status) was compared among 3,494 patients from 140 U.S. clinics. SES was categorized by total household income. Hierarchical multivariate linear regression estimated differences in KCCQ-os score after adjusting for 31 patient characteristics and 10 medications. RESULTS: Overall mean KCCQ-os scores were 64.2 ± 24.0 but lower for women (29% of sample; 60.3 ± 24.0 vs. 65.9 ± 24.0, respectively; p < 0.001), for blacks (60.5 ± 25.0 vs. 64.9 ± 23.0, respectively; p < 0.001), for Hispanics (59.1 ± 21.0 vs. 64.9 ± 23.0, respectively; p < 0.001), and for those with the lowest income (<$25,000; mean: 57.1 vs. 63.1 to 74.7 for other income categories; p < 0.001). Fully adjusted KCCQ-os scores were 2.2 points lower for women (95% confidence interval [CI]: -3.8 to -0.6; p = 0.007), no different for blacks (p = 0.74), 4.0 points lower for Hispanics (95% CI: -6.6 to -1.3; p = 0.003), and lowest in the poorest patients (4.7 points lower than those with the highest income (95% CI: 0.1 to 9.2; p = 0.045; p for trend = 0.003). CONCLUSIONS: Among outpatients with HFrEF, women, blacks, Hispanics, and poorer patients had worse health status, which remained significant for women, Hispanics, and poorer patients in fully adjusted analyses. This suggests an opportunity to further optimize treatment to reduce these observed disparities.

RESUMEN

BACKGROUND: Although a key treatment goal for patients with heart failure with reduced ejection fraction is to optimize their health status (their symptoms, function, and quality of life), the variability across outpatient practices in achieving this goal is unknown. METHODS AND RESULTS: In the CHAMP-HF (Change the Management of Patients With Heart Failure) registry, associations between baseline practice characteristics and Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary (OS) and Symptom Frequency (SF) scores were assessed in 3494 patients across 140 US practices using hierarchical regression after accounting for 23 patient and 11 treatment characteristics. We then calculated an adjusted median odds ratio to quantify the average difference in likelihood that a patient would have excellent (KCCQ-OS, ≥75) health status or minimal (monthly or fewer) symptoms (KCCQ-SF, ≥75) when treated at one practice versus another, at random. The mean (±SD) KCCQ-OS and KCCQ-SF were 64.2±24 and 68.9±25.6, with 40% (n=1380) and 50% (n=1760) having KCCQ scores ≥75, respectively. The adjusted median odds ratio across practices, for KCCQ-OS ≥75, was 1.70 (95% confidence interval, 1.54-1.99; P<0.001) indicating a median 70% higher odds of a patient having good-to-excellent health status when treated at one random practice versus another. In regard to KCCQ-SF, the adjusted median odds ratio for KCCQ-SF ≥75 was 1.54 (95% confidence interval, 1.41-1.76; P=0.001). CONCLUSIONS: In a large, contemporary registry of outpatients with chronic heart failure with reduced ejection fraction, we observed significant practice-level variability in patients' health status. Quantifying patients' health status as a measure of quality should be explored as a foundation for improving care. CLINICAL TRIAL REGISTRATION: URL: https://www.centerwatch.com.

RESUMEN

BACKGROUND: Prior studies have reported higher in-hospital survival with prompt defibrillation and epinephrine treatment in patients with in-hospital cardiac arrest (IHCA). Whether this survival benefit persists after discharge is unknown. METHODS: We linked data from a national IHCA registry with Medicare files and identified 36 961 patients ≥65 years of age with an IHCA at 517 hospitals between 2000 and 2011. Patients with IHCA caused by pulseless ventricular tachycardia or ventricular fibrillation were stratified by prompt (≤2 minutes) versus delayed (>2 minutes) defibrillation, whereas patients with IHCA caused by asystole or pulseless electric activity were stratified by prompt (≤5 minutes) versus delayed (>5 minutes) epinephrine treatment. The association between prompt treatment and long-term survival for each rhythm type was assessed with multivariable hierarchical modified Poisson regression models. RESULTS: Of 8119 patients with an IHCA caused by ventricular tachycardia or ventricular fibrillation, the rate of 1-year survival was higher in those treated with prompt defibrillation than with delayed defibrillation (25.7% [1466 of 5714] versus 15.5% [373 of 2405]; adjusted relative risk [RR], 1.49; 95% confidence interval [CI] 1.32-1.69; P<0.0001). This survival advantage persisted at 3 years (19.1% versus 11.0%; adjusted RR, 1.45; 95% CI, 1.23-1.69; P<0.0001) and at 5 years (14.7% versus 7.9%; adjusted RR, 1.50; 95% CI, 1.22-1.83; P<0.0001). Of 28 842 patients with an IHCA caused by asystole/pulseless electric activity, the rate of 1-year survival with prompt epinephrine treatment was higher than with delayed treatment (5.4% [1341 of 24 885] versus 4.3% [168 of 3957]; adjusted RR, 1.20; 95% CI, 1.02-1.41; P=0.02), but this survival benefit was no longer present at 3 years (3.5% versus 2.9%; adjusted RR, 1.17; 95% CI, 0.95-1.45; P=0.15) and at 5 years (2.3% versus 1.9%; adjusted RR, 1.18; 95% CI, 0.88-1.58; P=0.27). CONCLUSIONS: Prompt defibrillation for IHCA caused by ventricular tachycardia or ventricular fibrillation was associated with higher rates of long-term survival throughout 5 years of follow-up, whereas prompt epinephrine treatment for asystole/pulseless electric activity was associated with greater survival at 1 year but not at 3 or 5 years. By quantifying the greater survival associated with timely defibrillation and epinephrine administration, these findings provide important insights into the durability of survival benefits for 2 process-of-care measures in current resuscitation guidelines.

RESUMEN

BACKGROUND: Although noninvasive telemonitoring in patients with heart failure does not reduce mortality or hospitalizations, less is known about its effect on health status. This study reports the results of a randomized clinical trial of telemonitoring on health status in patients with heart failure. METHODS AND RESULTS: Among 1521 patients with recent heart failure hospitalization randomized in the Tele-HF trial (Telemonitoring to Improve Heart Failure Outcomes), 756 received telephonic monitoring and 765 usual care. Disease-specific health status was measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ) within 2 weeks of discharge and at 3 and 6 months. Repeated measures linear regression models were used to assess differences in KCCQ scores between patients assigned to telemonitoring and usual care over 6 months. The baseline characteristics of the 2 treatment arms were similar (mean age, 61 years; 43% female and 39% black). Over the 6-month follow-up period, there was a statistically significant, but clinically small, difference between the 2 groups in their KCCQ overall summary and subscale scores. The average KCCQ overall summary score for those receiving telemonitoring was 2.5 points (95% confidence interval, 0.38-4.67; P=0.02) higher than usual care, driven primarily by improvements in symptoms (3.5 points; 95% confidence interval, 1.18-5.82; P=0.003) and social function (3.1 points; 95% confidence interval, 0.30-6.00; P=0.03). CONCLUSIONS: Telemonitoring results in statistically significant, but clinically small, improvements in health status when compared with usual care. Given that the KCCQ was a secondary outcome, the benefits should be confirmed in future studies. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov/. Unique identifier: NCT00303212.
