The effect of kidney function on guideline-directed medical therapy implementation and prognosis in heart failure with reduced ejection fraction.

ABSTRACT:

Background

Kidney dysfunction (KD) is a main limiting factor of applying guideline-directed medical therapy (GDMT) and reaching the recommended target doses (TD) in heart failure (HF) with reduced ejection fraction (HFrEF).

Hypothesis

We aimed to assess the success of optimization, long-term applicability, and adherence of neurohormonal antagonist triple therapy (TT:RASi [ACEi/ARB/ARNI] + βB + MRA) according to the KD after a HF hospitalization and to investigate its impact on prognosis.

Methods

The data of 247 real-world, consecutive patients were analyzed who were hospitalized in 2019-2021 for HFrEF and then were followed-up for 1 year. The application and the ratio of reached TD of TT at hospital discharge and at 1 year were assessed comparing KD categories (eGFR: ≥90, 60-89, 45-59, 30-44, <30 mL/min/1.73 m² ). Moreover, 1-year all-cause mortality and rehospitalization rates in KD subgroups were investigated.

Results

Majority of the patients received TT at hospital discharge (77%) and at 1 year (73%). More severe KD led to a lower application ratio (p < .05) of TT (92%, 88%, 80%, 73%, 31%) at discharge and at 1 year (81%, 76%, 76%, 68%, 40%). Patients with more severe KD were less likely (p < .05) to receive TD of MRA (81%, 68%, 78%, 61%, 52%) at discharge and a RASi (53%, 49%, 45%, 21%, 27%) at 1 year. One-year all-cause mortality (14%, 15%, 16%, 33%, 48%, p < .001), the ratio of all-cause rehospitalizations (30%, 35%, 40%, 43%, 52%, p = .028), and rehospitalizations for HF (8%, 13%, 18%, 20%, 38%, p = .001) were significantly higher in more severe KD categories.

Conclusions

KD unfavorably affects the application of TT in HFrEF, however poorer mortality and rehospitalization rates among them highlight the role of the conscious implementation and up-titration of GDMT.

Project description:AimsGuideline-directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF) is recommended in clinical guidelines, but elderly patients have not fully received GDMT in the clinical situation. The aim of this study was to determine the clinical characteristics of patients who have not received GDMT and the association between implementation of GDMT at discharge and physical frailty in patients with HFrEF who were hospitalized for acute decompensated heart failure (ADHF).Methods and resultsThis study was a cross-sectional study with a retrospective analysis of the Kochi YOSACOI study, a prospective multicentre observational study that enrolled 1061 patients hospitalized for ADHF from May 2017 to December 2019 in Japan. Of 339 patients (32.0%) with HFrEF, 268 patients who were assessed for physical frailty by the Japanese version of the Cardiovascular Health Study criteria were divided into two groups: those with GDMT (135 patients, 50.4%) and those without GDMT (133 patients, 49.6%). GDMT was defined as the prescription of a combination of renin-angiotensin system (RAS) inhibitors (angiotensin-converting inhibitors or angiotensin receptor blockers) and beta-blockers. The median age of patients with HFrEF was 76 years (interquartile range, 67-83 years). Patients without GDMT were older than patients with GDMT (73 years vs. 78 years, P < 0.001). Patients without GDMT tended to have more prior HF admission than did patients with GDMT (P = 0.004), and patients without GDMT had lower levels of estimated glomerular filtration rate (P < 0.001) than those in patients with GDMT. Physical frailty was observed in 54.1% of the patients without GDMT and in 38.5% of the patients with GDMT (P = 0.014). Patients without GDMT had a higher rate of cognitive impairment than that in patients with GDMT (P = 0.009). RAS inhibitors only, beta-blockers only, and both RAS inhibitors and beta-blockers were less frequently prescribed in patients with physical frailty than in patients with physical non-frailty (52.0% vs. 86.7%, P < 0.05; 70.1% vs. 100.0%, P < 0.05; 42.5% vs. 86.7%, P < 0.01, respectively). In logistic regression analysis, compared with physical non-frailty, physical frailty was significantly associated with no implementation of GDMT (odds ratio: 6.900, 95% confidence interval: 1.420-33.600; P = 0.017), independent of older age and severe renal dysfunction.ConclusionsThe results of this study suggest that physical frailty is one of the factors that may withhold GDMT in patients with HFrEF.

Project description:ImportanceOptimal treatment of heart failure with reduced ejection fraction (HFrEF) is scripted by treatment guidelines, but many eligible patients do not receive guideline-directed medical therapy (GDMT) in clinical practice.ObjectiveTo determine whether a remote, algorithm-driven, navigator-administered medication optimization program could enhance implementation of GDMT in HFrEF.Design, setting, and participantsIn this case-control study, a population-based sample of patients with HFrEF was offered participation in a quality improvement program directed at GDMT optimization. Treating clinicians in a tertiary academic medical center who were caring for patients with heart failure and an ejection fraction of 40% or less (identified through an electronic health record-based search) were approached for permission to adjust medical therapy according to a sequential titration algorithm modeled on the current American College of Cardiology/American Heart Association heart failure guidelines. Navigators contacted participants by telephone to direct medication adjustment and conduct longitudinal surveillance of laboratory tests, blood pressure, and symptoms under supervision of a pharmacist, nurse practitioner, and heart failure cardiologist. Patients and clinicians declining to participate served as a control group.ExposuresNavigator-led remote optimization of GDMT compared with usual care.Main outcomes and measuresProportion of patients receiving GDMT in the intervention and control groups at 3 months.ResultsOf 1028 eligible patients (mean [SD] values: age, 68 [14] years; ejection fraction, 32% [8%]; and systolic blood pressure, 122 [18] mm Hg; 305 women (30.0%); 892 individuals [86.8%] in New York Heart Association class I and II), 197 (19.2%) participated in the medication optimization program, and 831 (80.8%) continued with usual care as directed by their treating clinicians (585 [56.9%] general cardiologists; 443 [43.1%] heart failure specialists). At 3 months, patients participating in the remote intervention experienced significant increases from baseline in use of renin-angiotensin system antagonists (138 [70.1%] to 170 [86.3%]; P < .001) and β-blockers (152 [77.2%] to 181 [91.9%]; P < .001) but not mineralocorticoid receptor antagonists (51 [25.9%] to 60 [30.5%]; P = .14). Doses for each category of GDMT also increased from baseline in the intervention group. Among the usual-care group, there were no changes from baseline in the proportion of patients receiving GDMT or the dose of GDMT in any category.Conclusions and relevanceRemote titration of GDMT by navigators using encoded algorithms may represent an efficient, population-level strategy for rapidly closing the gap between guidelines and clinical practice in patients with HFrEF.

Project description:IntroductionHeart failure is associated with recurrent hospitalizations and high mortality. Guideline directed medical treatment (GDMT), including beta blockers (BBs), angiotensin converting enzyme inhibitors (ACE-Is), angiotensin receptor blockers (ARBs) and aldosterone antagonists (AAs) has shown to improve outcomes. Current guidelines recommend the use of these medication classes at maximally tolerated dosages. Despite the evidence, < 25% of patients with heart failure with reduced left ventricular ejection fraction (HFrEF) are on the appropriate medical regimen titrated to the target doses. As such, we sought to assess the utility of a focused GDMT clinic to reduce this gap.MethodsWe conducted a retrospective chart review through existing patient data in a single center teaching hospital of patients referred to a focused GDMT clinic primarily staffed with heart failure trained nurse specialists, physician assistants and cardiologists. Management guidelines were developed with protocols for the initiation and uptitration of all therapeutic agents considered as GDMT.Our primary objective was to determine whether enrollment into a dedicated nursing led guideline directed medical therapy clinic would increase the proportion of patients with heart failure with reduced ejection fraction on appropriate medications as well as medication dosages in patients, the percentage of patients on the following medications and percentage at target doses: Renin-Angiotensin-Aldosterone System Blockers, Evidence Based Beta Blockers, and Aldosterone Antagonists. Our secondary objective was to determine if there was any clinical benefit on objective measures including renal function, hospital admissions, mortality and implantable defibrillator shocks.ResultsBetween October 2015 and March 2017, 63 patients were identified by requisition forms, in which 61 were able to be identified based on legibility of identifying information. Mean duration of follow up was 264.44 ± 162.68 days over 7 ± 3.94 days. Mean ejection fraction was 21.8 ± 7.3%. New onset cardiomyopathies (diagnosed within 30 days) compiled 21% of the patient population while those with demonstrated cardiomyopathies (> 90 days) compiled 48% of the patient population. Patients with NYHA class III heart failure compiled 65% of the patient population.There was a statistically significant increase in the mean number of GDMT at any dose (2.31 ± 0.76 to 2.74 ± 0.66; p < 0.001) and mean number of GDMT at target doses (0.54 ± 0.79 to 1.52 ± 1.1; p < 0.001). Percentage of the population that were on no target doses at initial visit was 62% which was reduced to 18% after intervention.Clinical improvement was reflected in significant improvement in ejection fraction from 21.8 ± 7.8% to 36.2 ± 14.3% (p < 0.001). Increases in sodium and chloride were statistically small but significant. There a significant reduction in heart failure hospitalizations in comparison to a year prior to after the initial encounter in the clinic (p < 0.001).ConclusionThis pilot study showed that a nurse directed GDMT titration program successfully increased the number of GDMT that patients were able to tolerate in a timely fashion, all the while enhancing ejection fraction, sodium and chloride levels, with a reduction in rehospitalization rates.
