<h4>Background</h4>The relationship between diuretic use or change in diuretic use and outcomes in chronic heart failure (HF) remains poorly defined. We evaluated the association between diuretic use and changes in health status, exercise capacity, and clinical events in a large randomized trial of subjects with HF.<h4>Methods</h4>HF-ACTION randomized 2,331 outpatients with HF and ejection fraction ≤35% to aerobic exercise training versus usual care. We grouped patients according to loop diureti ...[more]

Project description:ObjectivesThe aim of this study was to assess for a treatment interaction between statin use and exercise training (ET) response.BackgroundRecent data suggest that statins may attenuate ET response, but limited data exist in patients with heart failure (HF).MethodsHF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) was a randomized trial of 2,331 patients with chronic HF with ejection fraction ≤35% who were randomized to usual care with or without ET. We evaluated whether there was a treatment interaction between statins and ET response for the change in quality of life and aerobic capacity (peak oxygen consumption and 6-min walk distance) from baseline to 3 months. We also assessed for a treatment interaction among atorvastatin, simvastatin, and pravastatin and change in these endpoints with ET. Multiple linear regression analyses were performed for each endpoint, adjusting for baseline covariates.ResultsOf 2,331 patients in the HF-ACTION trial, 1,353 (58%) were prescribed statins at baseline. Patients treated with statins were more likely to be older men with ischemic HF etiology but had similar use of renin angiotensin system blockers and beta-blockers. There was no evidence of a treatment interaction between statin use and ET on changes in quality of life or exercise capacity, nor was there evidence of differential association between statin type and ET response for these endpoints (all p values >0.05).ConclusionsIn a large chronic HF cohort, there was no evidence of a treatment interaction between statin use and short-term change in aerobic capacity and quality of life with ET. These findings contrast with recent reports of an attenuation in ET response with statins in a different population, highlighting the need for future prospective studies.

Project description:AimsA 5-point change in the Kansas City Cardiomyopathy Questionnaire (KCCQ) is commonly considered to be a clinically significant difference in health status in patients with heart failure. We evaluated how the magnitude of change relates to subsequent clinical outcomes.Methods and resultsUsing data from the HF-ACTION trial of exercise training in chronic heart failure (n = 2331), we used multivariable Cox regression with piecewise linear splines to examine the relationship between change in KCCQ overall summary score from baseline to 3 months (range 0-100; higher scores reflect better health status) and subsequent all-cause mortality/hospitalization. Among 2038 patients with KCCQ data at the 3-month visit, KCCQ scores increased from baseline by ≥5 points for 45%, scores decreased by ≥5 points for 23%, and scores changed by <5 points for the remaining 32% of patients. There was a non-linear relationship between change in KCCQ and outcomes. Worsening health status was associated with increased all-cause mortality/hospitalization (adjusted hazard ratio 1.07 per 5-point KCCQ decline; 95% confidence interval 1.03-1.12; P < 0.001). In contrast, improving health status, up to an 8-point increase in KCCQ, was associated with decreased all-cause mortality/hospitalization (adjusted hazard ratio 0.93 per 5-point increase; 95% confidence interval 0.90-0.97; P < 0.001). Additional improvements in health status beyond an 8-point increase in KCCQ was not associated with all-cause death or hospitalization (P = 0.42).ConclusionIn patients with heart failure, small changes in KCCQ are associated with changing future risk, but more research will be necessary to understand how different magnitudes of improving health status affect outcomes.

Project description:ObjectivesThis study compared combination diuretic strategies in acute heart failure (AHF) complicated by diuretic resistance (DR).BackgroundCombination diuretic regimens to overcome loop DR are commonly used but with limited evidence.MethodsThis study was a randomized, double-blinded trial in 60 patients hospitalized with AHF and intravenous (IV) loop DR. Patients were randomized to oral metolazone, IV chlorothiazide, or tolvaptan therapy. All patients received concomitant high-dose IV infusions of furosemide. The primary outcome was 48-h weight loss.ResultsThe cohort exhibited DR prior to enrollment, producing 1,188 ± 476 ml of urine in 12 h during high-dose loop diuretic therapy (IV furosemide: 612 ± 439 mg/day). All 3 interventions significantly improved diuretic efficacy (p < 0.001). Compared to metolazone (4.6 ± 2.7 kg), neither IV chlorothiazide (5.8 ± 2.7 kg; 1.2 kg [95% confidence interval (CI)]: -2.9 to 0.6; p = 0.292) nor tolvaptan (4.1 ± 3.3 kg; 0.5 kg [95% CI: -1.5 to 2.4; p = 0.456) resulted in more weight loss at 48 h. Median (interquartile range [IQR]) cumulative urine output increased significantly and did not differ among those receiving metolazone (7.78 [IQR: 6.59 to 10.10] l) and chlorothiazide (8.77 [IQR: 7.37 to 10.86] l; p = 0.245) or tolvaptan (9.70 [IQR: 6.36 to 13.81] l; p = 0.160). Serum sodium decreased less with tolvaptan than with metolazone (+4 ± 5 vs. -1 ± 3 mEq/l; p = 0.001), but 48-h spot urine sodium was lower with tolvaptan (58 ± 25 mmol/l) than with metolazone (104 ± 16 mmol/l; p = 0.002) and with chlorothiazide (117 ± 14 mmol/l; p < 0.001).ConclusionsIn this moderately sized DR trial, weight loss was excellent with the addition of metolazone, IV chlorothiazide, or tolvaptan to loop diuretics, without a detectable between-group difference.

Project description:PurposeLoop diuretics are recommended to treat congestive symptoms in patients with heart failure. However, observational studies have indicated that loop diuretic treatment in heart failure is associated with increased mortality. Therefore, loop diuretic discontinuation or dose reduction, when clinically possible, is recommended. Our aim was to study nationwide temporal trends in loop diuretic treatment from 2005 to 2014 in real-life patients with chronic heart failure.MethodsData from the nationwide Swedish National Patient, Prescribed Drug and Cause of Death Registers were linked. The annual proportions of patients with chronic heart failure treated with loop diuretics from 2005 to 2014 were calculated. In addition, the annual median loop diuretic doses (DDD) in patients with chronic heart failure treated with loop diuretics from 2005 to 2014 were calculated.ResultsThe proportion of real-life patients with chronic heart failure treated with loop diuretics decreased from 73.2% in 2005 to 65.7% in 2014 (p for trend < 0.001). The median loop diuretic DDD in real-life patients with chronic heart failure decreased from 2.13 (IQR 1.09-2.77) in 2005 to 1.63 (IQR 1.09-2.25) in 2014 (p = 0.001 for trend).ConclusionsLoop diuretic treatment decreased from 2005 to 2014 in real-life patients with chronic heart failure. The prognostic impact of changes in loop diuretic treatment in patients with heart failure remains unclear.

Project description:BackgroundIn the DAPA-HF trial (Dapagliflozin and Prevention of Adverse-Outcomes in Heart Failure), the sodium-glucose cotransporter 2 inhibitor dapagliflozin reduced the risk of worsening heart failure and death in patients with heart failure and reduced ejection fraction. We examined the efficacy and tolerability of dapagliflozin in relation to background diuretic treatment and change in diuretic therapy after randomization to dapagliflozin or placebo.MethodsWe examined the effects of study treatment in the following subgroups: no diuretic and diuretic dose equivalent to furosemide <40, 40, and >40 mg daily at baseline. We examined the primary composite end point of cardiovascular death or a worsening heart failure event and its components, all-cause death and symptoms.ResultsOf 4616 analyzable patients, 736 (15.9%) were on no diuretic, 1311 (28.4%) were on <40 mg, 1365 (29.6%) were on 40 mg, and 1204 (26.1%) were taking >40 mg. Compared with placebo, dapagliflozin reduced the risk of the primary end point across each of these subgroups: hazard ratios were 0.57 (95% CI, 0.36-0.92), 0.83 (95% CI, 0.63-1.10), 0.77 (95% CI, 0.60-0.99), and 0.78 (95% CI, 0.63-0.97), respectively (P for interaction=0.61). The hazard ratio in patients taking any diuretic was 0.78 (95% CI, 0.68-0.90). Improvements in symptoms and treatment toleration were consistent across the diuretic subgroups. Diuretic dose did not change in most patients during follow-up, and mean diuretic dose did not differ between the dapagliflozin and placebo groups after randomization.ConclusionsThe efficacy and safety of dapagliflozin were consistent across the diuretic subgroups examined in DAPA-HF.

Project description:The purpose of this study was to investigate whether a surrogate for renal neurohormonal activation, blood urea nitrogen (BUN), could identify patients destined to experience adverse outcomes associated with the use of high-dose loop diuretics (HDLD).Loop diuretics are commonly used to control congestive symptoms in heart failure; however, these agents cause neurohormonal activation and have been associated with worsened survival.Subjects in the BEST (Beta-Blocker Evaluation of Survival Trial) receiving loop diuretics at baseline were analyzed (N = 2,456). The primary outcome was the interaction between BUN- and HDLD-associated mortality.In the overall cohort, HDLD use (?160 mg/day) was associated with increased mortality (hazard ratio [HR]: 1.56; 95% confidence interval [CI]: 1.35 to 1.80). However, after extensively controlling for baseline characteristics, this association did not persist (HR: 1.06; 95% CI: 0.89 to 1.25). In subjects with BUN levels above the median (21.0 mg/dl), both the unadjusted (HR: 1.59; 95% CI: 1.34 to 1.88) and adjusted (HR: 1.29; 95% CI: 1.07 to 1.60) risk of death was higher in the HDLD group. In patients with BUN levels below the median, there was no associated risk with HDLD (HR: 0.99; 95% CI: 0.75 to 1.34) and after controlling for baseline characteristics, the HDLD group had significantly improved survival (HR: 0.71; 95% CI: 0.49 to 0.96) (p interaction = 0.018).The risk associated with HDLD use is strongly dependent on BUN concentrations with reduced survival in patients with an elevated BUN level and improved survival in patients with a normal BUN level. These data suggest a role for neurohormonal activation in loop diuretic-associated mortality.

Project description:Guidelines recommend that exercise training be considered for medically stable outpatients with heart failure. Previous studies have not had adequate statistical power to measure the effects of exercise training on clinical outcomes.To test the efficacy and safety of exercise training among patients with heart failure.Multicenter, randomized controlled trial of 2331 medically stable outpatients with heart failure and reduced ejection fraction. Participants in Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) were randomized from April 2003 through February 2007 at 82 centers within the United States, Canada, and France; median follow-up was 30 months.Usual care plus aerobic exercise training, consisting of 36 supervised sessions followed by home-based training, or usual care alone.Composite primary end point of all-cause mortality or hospitalization and prespecified secondary end points of all-cause mortality, cardiovascular mortality or cardiovascular hospitalization, and cardiovascular mortality or heart failure hospitalization.The median age was 59 years, 28% were women, and 37% had New York Heart Association class III or IV symptoms. Heart failure etiology was ischemic in 51%, and median left ventricular ejection fraction was 25%. Exercise adherence decreased from a median of 95 minutes per week during months 4 through 6 of follow-up to 74 minutes per week during months 10 through 12. A total of 759 patients (65%) in the exercise training group died or were hospitalized compared with 796 patients (68%) in the usual care group (hazard ratio [HR], 0.93 [95% confidence interval {CI}, 0.84-1.02]; P = .13). There were nonsignificant reductions in the exercise training group for mortality (189 patients [16%] in the exercise training group vs 198 patients [17%] in the usual care group; HR, 0.96 [95% CI, 0.79-1.17]; P = .70), cardiovascular mortality or cardiovascular hospitalization (632 [55%] in the exercise training group vs 677 [58%] in the usual care group; HR, 0.92 [95% CI, 0.83-1.03]; P = .14), and cardiovascular mortality or heart failure hospitalization (344 [30%] in the exercise training group vs 393 [34%] in the usual care group; HR, 0.87 [95% CI, 0.75-1.00]; P = .06). In prespecified supplementary analyses adjusting for highly prognostic baseline characteristics, the HRs were 0.89 (95% CI, 0.81-0.99; P = .03) for all-cause mortality or hospitalization, 0.91 (95% CI, 0.82-1.01; P = .09) for cardiovascular mortality or cardiovascular hospitalization, and 0.85 (95% CI, 0.74-0.99; P = .03) for cardiovascular mortality or heart failure hospitalization. Other adverse events were similar between the groups.In the protocol-specified primary analysis, exercise training resulted in nonsignificant reductions in the primary end point of all-cause mortality or hospitalization and in key secondary clinical end points. After adjustment for highly prognostic predictors of the primary end point, exercise training was associated with modest significant reductions for both all-cause mortality or hospitalization and cardiovascular mortality or heart failure hospitalization.clinicaltrials.gov Identifier: NCT00047437.

Project description:Psychosocial factors may influence adherence with exercise training for heart failure (HF) patients. We aimed to describe the association between social support and barriers to participation with exercise adherence and clinical outcomes.Of patients enrolled in Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION), 2279 (97.8%) completed surveys to assess social support and barriers to exercise, resulting in the perceived social support score (PSSS) and barriers to exercise score (BTES). Higher PSSS indicated higher levels of social support, whereas higher BTES indicated more barriers to exercise. Exercise time at 3 and 12 months correlated with PSSS (r= 0.09 and r= 0.13, respectively) and BTES (r=-0.11 and r=-0.12, respectively), with higher exercise time associated with higher PSSS and lower BTES (All P<0.005). For cardiovascular death or HF hospitalization, there was a significant interaction between the randomization group and BTES (P=0.035), which corresponded to a borderline association between increasing BTES and cardiovascular death or HF hospitalization in the exercise group (hazard ratio 1.25, 95% confidence interval 0.99, 1.59), but no association in the usual care group (hazard ratio 0.83, 95% confidence interval 0.66, 1.06).Poor social support and high barriers to exercise were associated with lower exercise time. PSSS did not impact the effect of exercise training on outcomes. However, for cardiovascular death or HF hospitalization, exercise training had a greater impact on patients with lower BTES. Given that exercise training improves outcomes in HF patients, assessment of perceived barriers may facilitate individualized approaches to implement exercise training therapy in clinical practice.URL: http://www.clinicaltrials.gov.

Project description:Depression is common in patients with cardiac disease, especially in patients with heart failure, and is associated with increased risk of adverse health outcomes. Some evidence suggests that aerobic exercise may reduce depressive symptoms, but to our knowledge the effects of exercise on depression in patients with heart failure have not been evaluated.To determine whether exercise training will result in greater improvements in depressive symptoms compared with usual care among patients with heart failure.Multicenter, randomized controlled trial involving 2322 stable patients treated for heart failure at 82 medical clinical centers in the United States, Canada, and France. Patients who had a left ventricular ejection fraction of 35% or lower, had New York Heart Association class I to IV heart failure, and had completed the Beck Depression Inventory II (BDI-II) score were randomized (1:1) between April 2003 and February 2007. Depressive scores ranged from 0 to 59; scores of 14 or higher are considered clinically significant.Participants were randomized either to supervised aerobic exercise (goal of 90 min/wk for months 1-3 followed by home exercise with a goal of ?120 min/wk for months 4-12) or to education and usual guideline-based heart failure care.Composite of death or hospitalization due to any cause and scores on the BDI-II at months 3 and 12.Over a median follow-up period of 30 months, 789 patients (68%) died or were hospitalized in the usual care group compared with 759 (66%) in the aerobic exercise group (hazard ratio [HR], 0.89; 95% CI, 0.81 to 0.99; P = .03). The median BDI-II score at study entry was 8, with 28% of the sample having BDI-II scores of 14 or higher. Compared with usual care, aerobic exercise resulted in lower mean BDI-II scores at 3 months (aerobic exercise, 8.95; 95% CI, 8.61 to 9.29 vs usual care, 9.70; 95% CI, 9.34 to 10.06; difference, -0.76; 95% CI,-1.22 to -0.29; P = .002) and at 12 months (aerobic exercise, 8.86; 95% CI, 8.67 to 9.24 vs usual care, 9.54; 95% CI, 9.15 to 9.92; difference, -0.68; 95% CI, -1.20 to -0.16; P = .01).Compared with guideline-based usual care, exercise training resulted in a modest reduction in depressive symptoms, although the clinical significance of this improvement is unknown.clinicaltrials.gov Identifier: NCT00047437.

Project description:Findings from previous studies of the effects of exercise training on patient-reported health status have been inconsistent.To test the effects of exercise training on health status among patients with heart failure.Multicenter, randomized controlled trial among 2331 medically stable outpatients with heart failure with left ventricular ejection fraction of 35% or less. Patients were randomized from April 2003 through February 2007.Usual care plus aerobic exercise training (n = 1172), consisting of 36 supervised sessions followed by home-based training, vs usual care alone (n = 1159). Randomization was stratified by heart failure etiology, which was a covariate in all models.Kansas City Cardiomyopathy Questionnaire (KCCQ) overall summary scale and key subscales at baseline, every 3 months for 12 months, and annually thereafter for up to 4 years. The KCCQ is scored from 0 to 100 with higher scores corresponding to better health status. Treatment group effects were estimated using linear mixed models according to the intention-to-treat principle.Median follow-up was 2.5 years. At 3 months, usual care plus exercise training led to greater improvement in the KCCQ overall summary score (mean, 5.21; 95% confidence interval, 4.42 to 6.00) compared with usual care alone (3.28; 95% confidence interval, 2.48 to 4.09). The additional 1.93-point increase (95% confidence interval, 0.84 to 3.01) in the exercise training group was statistically significant (P < .001). After 3 months, there were no further significant changes in KCCQ score for either group (P = .85 for the difference between slopes), resulting in a sustained, greater improvement overall for the exercise group (P < .001). Results were similar on the KCCQ subscales, and no subgroup interactions were detected.Exercise training conferred modest but statistically significant improvements in self-reported health status compared with usual care without training. Improvements occurred early and persisted over time.clinicaltrials.gov Identifier: NCT00047437.
