Project description:AimsIn older patients, guideline-directed medical therapy (GDMT) for heart failure (HF) with reduced ejection fraction (<40%; HFrEF) is not contraindicated, but adherence to guidelines is limited. We investigated the implementation of GDMT in HFrEF across different age strata in a large nationwide cohort.Methods and resultsPatients with HFrEF and HF duration ≥3 months registered in the Swedish HF Registry between 2000-2018 were analysed according to age. Multivariable logistic and multinomial regressions were fitted to investigate factors associated with underuse/underdosing. Of 27 430 patients, 31% were <70 years old, 34% 70-79 years old, and 35% ≥80 years old. Use of treatments progressively decreased with increasing age. Use of renin-angiotensin system/angiotensin receptor-neprilysin inhibitors, beta-blockers and mineralocorticoid receptor antagonists was 80%, 88% and 35% in age ≥80 years; 90%, 93% and 47% in age 70-79 years; and 95%, 95% and 54% in age <70 years, respectively. Among patients with an indication, use of implantable cardioverter defibrillator and cardiac resynchronization therapy (CRT) was 7% and 23% in age ≥ 80 years; 22% and 42% in age 70-79 years; and 29% and 50% in age <70 years, respectively. Older patients were less likely treated with target doses or combinations of HF medications. Except for CRT, after extensive adjustments, age was inversely associated with the likelihood of GDMT use and target dose achievement.ConclusionIn HFrEF, gaps persist in the use of medications and devices. In disagreement with current recommendations, older patients remain undertreated. Improving strategies and a more individualized approach for implementing use of GDMT in HFrEF are required, particularly in older patients.

Project description:AimsThis study aimed to investigate the prognostic value of dynamic changes in left ventricular ejection fraction (EF) for cardiovascular (CV) outcomes in an all-comer heart failure (HF) population with reduced EF (HFrEF, EF < 40%). We sought to identify independent factors related to improvement in EF and to identify risk factors for increased risk of CV events in the subgroups of improved EF (iEF) and non-improved EF (niEF), respecively.Methods and resultsThis is a retrospective sub-analysis from the REDEAL HF trial, which included consecutive patients with chronic HF who were hospitalized from July 2009 to December 2017. Baseline and follow-up echocardiography data (interval ≥12 months) of 573 consecutive patients with HFrEF were analysed. iEF was defined as absolute improvement in EF ≥ 10% and follow-up EF over 40%. The primary endpoint was defined as a composite endpoint of cardiovascular (CV) death, CV hospitalization, or appropriate implantable cardioverter-defibrillator (ICD) therapy for ventricular arrhythmia. EF improved in 37.2% of patients with HFrEF during follow-up (median period of 17 months). iEF was independently associated with shorter HF duration (>4 vs. ≤4 years, odd ratio [OR] = 0.477, 95% CI 0.305-0.745), no coronary artery disease (CAD vs. no CAD, OR = 0.583, 95% CI 0.396-0.858), and no ICD implantation (ICD vs. no ICD, OR = 0.341, 95% CI 0.228-0.511). Compared with niEF, iEF was significantly and independently associated with lower all-cause mortality (22.1% vs. 31.1%, P = 0.019; hazard ratio [HR] = 0.674, 95% CI 0.469-0.968), lower CV mortality (8.9% vs. 16.1%, P = 0.015; HR = 0.539, 95% CI 0.317-0.916), and lower CV events risk (27.2% vs. 49.2%, P < 0.001; HR 0.519, 95% CI 0.381-0.708), after adjustment for age, sex, duration of HF, and other clinical risk factors. Hypertension (HR = 2.452, P = 0.032) and elevated N-terminal prohormone of brain natriuretic peptide (NT-proBNP >1153 pg/mL, HR = 4.372, P < 0.001) were identified as independent risk factors for CV events in the iEF subgroup. ICD implantation (HR = 1.533, P = 0.011), elevated NT-proBNP (HR = 1.626, P = 0.018), increased left atrial volume index (HR = 1.461, P = 0.021), reduced lateral mitral annular plane systolic excursion (HR = 1.478, P = 0.025), and reduced tricuspid plane systolic excursion (HR = 1.491, P = 0.039) were identified as risk factors for CV events in the niEF subgroup.ConclusionsImprovement in EF is independently related to the longer survival and lower CV related mortality and hospitalization rate of HFrEF. Elevated baseline NT-proBNP is identified as the strongest prognostic factor associated with increased CV events risk in HFrEF patients both with and without improved EF, regardless of age, sex, duration of HF, and other clinical risk factors.

Project description:AimsHeart failure with mildly reduced ejection fraction (HFmrEF) is associated with a favourable prognosis compared with heart failure (HF) with reduced ejection fraction (EF). We assessed whether left ventricular ejection fraction (LVEF) trajectory can be used to identify groups of patients with HFmrEF who have different clinical outcomes in a large retrospective study of patients with serial imaging.Methods and resultsPatients with HF and ≥2 echocardiograms performed ≥6 months apart were included if the LVEF measured 40-49% on the second study. Patients were classified as HFmrEF-Increasing if LVEF had increased ≥10% (n = 450), HFmrEF-Decreasing if LVEF had decreased ≥10% (n = 512), or HFmrEF-Stable if they did not meet other criteria (n = 389). The primary outcome was all-cause mortality or cardiovascular hospitalization after the second echocardiogram. Associations with time to first event were assessed with multivariable Cox analyses adjusted for age, co-morbidities, and medications. In total, 1351 patients with HFmrEF (median age 74, 64.2% male) were included with 28.8% exhibiting stable LVEF. During median follow-up of 15.3 months, the composite outcome occurred in 811 patients. During follow-up, patients with HFmrEF-Increasing were less likely to experience the primary outcome [adjusted hazard ratio (HR) 0.72, 95% confidence interval (CI) 0.60-0.88, P < 0.001] compared with HFmrEF-Stable. Patients with HFmrEF-Decreasing were more likely to experience the composite outcome in unadjusted analyses (unadjusted HR 1.19, 95% CI 1.01-1.40, P = 0.040) but not adjusted analyses (adjusted HR 1.16, 95% CI 0.98-1.37, P = 0.092). Associations with death or HF hospitalizations were similar (HFmrEF-Increasing: adjusted HR 0.72, 95% CI 0.59-0.88, P = 0.005; HFmrEF-Decreasing: adjusted HR 1.20, 95% CI 1.01-1.44, P = 0.044). Patients with HFmrEF-Decreasing had a similar risk of the composite outcome as patients with HF with reduced EF (adjusted HR 1.03, 95% CI 0.89-1.20, P = 0.670). Patients with HFmrEF-Increasing were less likely to experience the composite outcome compared with patients with HF with preserved EF (adjusted HR 0.73, 95% CI 0.62-0.87, P < 0.001).ConclusionsAmongst patients with HFmrEF, those exhibiting positive LVEF trajectory were less likely to experience adverse outcomes after correcting for important confounders including medical therapy. Categorizing HFmrEF patients based on LVEF trajectory provides meaningful clinical information and may assist clinicians with management decisions.

Project description:Heart failure (HF) can occur in patients with preserved (HFpEF, EF?50%) or reduced (HFrEF, EF<50%) ejection fraction (EF), but changes in EF after HF diagnosis are not well described.Among a community cohort of incident HF patients diagnosed from 1984 to 2009 in Olmsted County, Minnesota, we obtained all EFs assessed by echocardiography from initial HF diagnosis until death or last follow-up through March 2010. Mixed effects models fit a unique linear regression line for each person using serial EF data. Compiled results allowed estimates of the change in EF over time in HFpEF and HFrEF. Among 1233 HF patients (48.3% male, mean age 75.0 years, mean follow-up 5.1 years), 559 (45.3%) had HFpEF at diagnosis. In HFpEF, on average, EF decreased by 5.8% over 5 years (P<0.001) with greater declines in older individuals and those with coronary disease. Conversely, EF increased in HFrEF (average increase 6.9% over 5 years, P<0.001). Greater increases were noted in women, younger patients, individuals without coronary disease, and those treated with evidence-based medications. Overall, 39% of HFpEF patients had an EF<50% and 39% of HFrEF patients had an EF?50% at some point after diagnosis. Decreases in EF over time were associated with reduced survival whereas increases in EF were associated with improved survival.These data suggest that progressive contractile dysfunction may contribute to the pathophysiology of HFpEF. Prospective longitudinal studies are needed to confirm these observations and establish the mechanism and clinical relevance of decline in EF over time in HFpEF.

Project description:BackgroundChronic congestive heart failure is a common condition that, if untreated, markedly impairs the quality of life and is associated with a high risk of recurrent hospitalization and death.MethodsThis review is based on articles retrieved by a selective search in PubMed, as well as on relevant guidelines.ResultsEvidence-based treatment options are available only for congestive heart failure with a low ejection fraction. Pharma - cotherapy is based on neurohumoral inhibition of the renin-angiotensin-aldosterone system and the adrenergic system. The prognosis of patients with this condition has been further improved recently through the introduction of combined angiotensin receptor antagonists and neprilysin inhibitors. Modern implantable devices are a further component of treatment. Implantable defibrillators and special pacemakers for cardiac resynchronization are well established; the utility of alternative devices (baroreflex modulation or cardiac contractility modulation) needs to be investigated in further studies. It was recently shown that the catheter-based treatment of secondary mitral regurgitation with a MitraClip improves the outcome of selected patients.ConclusionThe treatment of chronic systolic heart failure as recommended in the relevant guidelines, with drugs and implanted devices if indicated, can significantly improve the clinical outcome.

Project description:Left ventricular remodeling, as commonly measured by left ventricular ejection fraction (LVEF), is associated with clinical outcomes. Although change in LVEF over time should reflect response to therapy and clinical course, serial measurement of LVEF is inconsistently performed in observational settings, and the incremental prognostic value of change in LVEF has not been well characterized. The β-Blocker Evaluation of Survival Trial measured LVEF by radionuclide ventriculography at baseline and at 3 and 12 months after randomization. We built a series of multivariable models with 16 clinical parameters plus change in LVEF for predicting 4 major clinical end points, including the trial's primary end point of all-cause mortality. Among 2484 patients with at least 1 follow-up LVEF, change in LVEF was the second most significant predictor (behind baseline creatinine) of all-cause mortality (adjusted hazard ratio for improvement in LVEF by ≥5 U responder versus nonresponder [95% confidence intervals] for all-cause mortality=0.62 [0.52-0.73]). Other end points, including heart failure hospitalization or the composite of all-cause mortality and heart failure hospitalization, yielded similar results. LVEF change ≥5 U was associated with a modest increase in discrimination when added to traditional predictors and was predictive of outcomes in both the bucindolol and placebo treatment groups. LVEF change as a predictor of outcomes was affected by sex and race, with evidence that LVEF improvement is associated with less survival benefit in African Americans and women. Serial evaluation for LVEF change predicts both survival and heart failure hospitalization and provides a dynamic/real-time measure of prognosis in heart failure with reduced LVEF.

Project description:Heart failure management has been repeatedly reviewed over time. This strategy has resulted in improved quality of life, especially in patients with heart failure with reduced ejection fraction (HFrEF). It is for this reason that new mechanisms involved in the development and progression of heart failure, along with specific therapies, have been identified. This review focuses on the most recent guidelines of therapeutic interventions, trials that explore novel therapies, and also new molecules that could improve prognosis of different HFrEF phenotypes.

Project description:BackgroundMicrovascular dysfunction plays an important role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). However, no mechanistic link between systemic microvasculature and congestion, a central feature of the syndrome, has yet been investigated.ObjectivesThis study aimed to investigate capillary-interstitium fluid exchange in HFpEF, including lymphatic drainage and the potential osmotic forces exerted by any hypertonic tissue Na+ excess.MethodsPatients with HFpEF and healthy control subjects of similar age and sex distributions (n = 16 per group) underwent: 1) a skin biopsy for vascular immunohistochemistry, gene expression, and chemical (water, Na+, and K+) analyses; and 2) venous occlusion plethysmography to assess peripheral microvascular filtration coefficient (measuring capillary fluid extravasation) and isovolumetric pressure (above which lymphatic drainage cannot compensate for fluid extravasation).ResultsSkin biopsies in patients with HFpEF showed rarefaction of small blood and lymphatic vessels (p = 0.003 and p = 0.012, respectively); residual skin lymphatics showed a larger diameter (p = 0.007) and lower expression of lymphatic differentiation and function markers (LYVE-1 [lymphatic vessel endothelial hyaluronan receptor 1]: p < 0.05; PROX-1 [prospero homeobox protein 1]: p < 0.001) compared with control subjects. In patients with HFpEF, microvascular filtration coefficient was lower (calf: 3.30 [interquartile range (IQR): 2.33 to 3.88] l × 100 ml of tissue-1 × min-1 × mm Hg-1 vs. 4.66 [IQR: 3.70 to 6.15] μl × 100 ml of tissue-1 × min-1 × mm Hg-1; p < 0.01; forearm: 5.16 [IQR: 3.86 to 5.43] l × 100 ml of tissue-1 × min-1 × mm Hg-1 vs. 5.66 [IQR: 4.69 to 8.38] μl × 100 ml of tissue-1 × min-1 × mm Hg-1; p > 0.05), in keeping with blood vascular rarefaction and the lack of any observed hypertonic skin Na+ excess, but the lymphatic drainage was impaired (isovolumetric pressure in patients with HFpEF vs. control subjects: calf 16 ± 4 mm Hg vs. 22 ± 4 mm Hg; p < 0.005; forearm 17 ± 4 mm Hg vs. 25 ± 5 mm Hg; p < 0.001).ConclusionsPeripheral lymphatic vessels in patients with HFpEF exhibit structural and molecular alterations and cannot effectively compensate for fluid extravasation and interstitial accumulation by commensurate drainage. Reduced lymphatic reserve may represent a novel therapeutic target.

Project description:Heart failure is a common entity encountered in healthcare with a vast socioeconomic impact. Recent advances in pharmacotherapy have led to the development of novel therapies with mortality benefits, improvement in heart failure symptoms and hospitalizations. This article is intended to explore those newer pharmacotherapies and summarize the evidence behind guideline directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF). It has been several years since any significant advances in pharmacotherapy of heart failure have resulted in survival benefit. Angiotensin-neprilysin inhibitors through the PARADIGM-HF and PIONEER-HF trials have shown mortality benefits and a reduction in heart failure hospitalizations and are considered landmark trials in heart failure. Vericiguat is an oral guanylate cyclase stimulator that through the recent VICTORIA trial showed a 10% relative difference in death from cardiovascular cause or hospitalization for heart failure. The sodium-glucose transport protein 2 (SGLT2) inhibitors are another class of medications that have shown promise in the treatment of patients with HFrEF and diabetes mellitus. The CANVAS and EMPA-REG OUTCOME trials showed the potential benefit of SGLT2 inhibitors on cardiovascular mortality, DECLARE-TIMI 58 trial showed that treatment with dapagliflozin reduced the risk of cardiovascular death or hospitalization for heart failure to a greater extent in patients with reduced ejection fraction (EF). Although novel pharmacotherapy is the current focus of intense research, there have been numerous studies on potential benefit of iron supplementation in ferropenic patients with heart failure. Another rapidly expanding area of research in the realm of heart failure is precision medicine and its impact on the development, progression, and treatment of heart failure. The field of heart failure is dynamic and with the influx of data from recent and ongoing trials, newer therapies with morbidity and mortality benefits in HFrEF are now available, nonetheless, much work is still needed.

Project description:ObjectiveThe study investigates the prognostic impact of body mass index (BMI) in patients hospitalized with heart failure with mildly reduced ejection fraction (HFmrEF).BackgroundLimited data regarding the prognostic impact of BMI in patients with HFmrEF is available.MethodsConsecutive patients with HFmrEF (ie, left ventricular ejection fraction 41-49% and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. Risk stratification was performed according to WHO-defined BMI groups. The primary endpoint was all-cause mortality at 30 months (median follow-up). Kaplan-Meier, uni- and multivariable Cox proportional regression analyses were applied for statistics.Results1832 consecutive patients with HFmrEF were included with a median BMI of 26.7 kg/m2 (IQR 24.0-30.8 kg/m2). Patients with lowest BMI (ie, 18.5-24.9 kg/m2) were associated with highest risk of all-cause mortality at 30 months compared to patients with higher BMI values (40.0% vs 29.0% vs 21.4% vs 20.9%; log rank p = 0.001; HR = 0.721; 95% CI 0.656-0.793; p = 0.001). Even after multivariable adjustment, higher BMI values were associated with improved survival at 30 months (HR = 0.963; 95% CI 0.943-0.985; p = 0.001). In contrast, the risk of HF- related rehospitalization at 30 months was not affected by BMI (log rank p = 0.064).ConclusionIn patients hospitalized with HFmrEF, lower BMI was associated with increased risk of all-cause mortality at 30 months, suggesting an obesity paradox in HFmrEF.
