Novel Initiative Increasing GDMT Use Among Patients With Heart Failure With Reduced Ejection Fraction.

Guideline-directed medical therapy utilization in patients with heart failure with reduced ejection fraction (HFrEF) remains low despite benefits in morbidity and mortality. The authors describe a unique quality improvement initiative designed to increase angiotensin receptor-neprilysin inhibitor (ARNI) and mineralocorticoid receptor antagonist (MRA) utilization in outpatients with HFrEF in a large cardiology practice, whereby eligible patients were identified in a standardized review process and medication utilization rates were linked to group quality metrics. Eligible HFrEF patients were defined as having a left ventricular ejection fraction (LVEF) ≤40% and NYHA functional class II to IV level of symptoms. Those with an LVEF >40%, no documented LVEF, or with NYHA functional class I symptoms were excluded. ARNI utilization was defined as any dose of sacubitril/valsartan prescribed, and MRA utilization was defined as any dose of either spironolactone or eplerenone prescribed. Group quality metric targets were set at >25% ARNI prescription and >60% MRA prescription in eligible patients. Following project implementation, ARNI utilization rose from 31% to 67% and MRA increased from 28% to 66%. Establishing clear quality metrics and formulating a proactive evaluation process was associated with a significant increase in prescription rates.

Heterogeneity of health status treatment response with sacubitril/valsartan: insights from the CHAMP-HF registry.

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.

Association between sacubitril/valsartan initiation and real-world health status trajectories over 18 months in heart failure with reduced ejection fraction.

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.

Efficacy of Sacubitril/Valsartan in the Setting of Acute Heart Failure: A Systematic Review.

Acute decompensated heart failure (ADHF) is one of the conditions associated with high rates of mortality and morbidity, in addition to its economic burden. Sacubitril/valsartan, the emerging drug in the field of heart failure, has been showing favorable outcomes in patients with heart failure with reduced ejection fraction (HFrEF). However, its efficacy in patients with acute decompensated heart failure remains obscure. This systematic review aims to offer more clarity to this established gap of knowledge. PubMed, ScienceDirect, and ScienceOpen were explored to gain access to studies on this topic. We conducted a systematic review to evaluate the safety and efficacy of using sacubitril/valsartan in the acute setting. Five clinical trials, 10 observational studies, including two abstracts, in addition to seven case reports and one editorial, were obtained and analyzed. Key outcomes of interest were safety and tolerability, efficacy reflected by N-terminal proB-type natriuretic peptide (NT-proBNP), and other serum and echocardiographic parameters. Additionally, target dose attainment, rehospitalization rates, and hemodynamics effect were also outcomes of interest. Based on our findings, the use of sacubitril/valsartan in patients with ADHF and cardiogenic shock is an effective measure. Although most of the results pointed to its safety, some of them showed the outcome of serious adverse events recommending its cautious use.

Milestones in Heart Failure: How Far We Have Come and How Far We Have Left to Go.

Heart failure is a clinically complex syndrome that results due to the failure of the ventricles to function as pump and oxygenate end organs. The repercussions of inadequate perfusion are seen in the form of sympathetic overactivation and third spacing, leading to clinical signs of increased blood pressure, dyspnea, fatigue, palpitations, etc. This article provided a brief overview of the clinical syndrome of heart failure; its epidemiology, risk factors, symptoms, and staging; and the mechanisms involved in disease progression. This article also described several landmark trials in heart failure that tested the efficacy of first-line drugs such as beta-blockers, angiotensin receptor blockers, angiotensin-converting enzyme inhibitors, and the latest drugs in the field of heart failure: angiotensin receptor neprilysin inhibitors. Most studies described in this article were guideline-setting trials that revolutionized the practice of medicine and cardiology.
