Initiation and Up-Titration of Guideline-Based Medications in Hospitalized Acute Heart Failure Patients - A Report From the West Tokyo Heart Failure Registry

Effect of basic activities of daily living independence on home discharge and long-term outcomes in patients hospitalized with heart failure

Patients hospitalized for heart failure (HF) experience impairments in functional status, primarily affecting basic activities of daily living (ADL). We investigated the independent effect of functional status for ADL on patient-centered outcomes (i.e., home discharge) and conventional clinical outcomes in HF. We analyzed 2936 consecutive hospitalized patients with HF from a prospective multicenter registry. The functional status of ADL was assessed before discharge by using the Barthel index (BI). Patients were categorized into the lower BI group (≤85; the lowest tertile) and higher BI group (>85). We evaluated the risk-adjusted association between BI and non-home discharge, as well as the two-year all-cause mortality. Exploratory subgroups included patients categorized by age, sex, HF hospitalization, left ventricular ejection fraction, body mass index, and estimated glomerular filtration rate (eGFR). Of the participants (age: 79 [69-85] years; 41.1% women), 86.3% were discharged home. A lower BI was independently associated with non-home discharge (OR: 5.12, 95% CI 3.86-6.80) and higher all-cause mortality rates (HR: 1.96, 95% CI 1.58-2.45). Two-year cardiac and non-cardiac mortality rates were higher in the lower BI group; however, the proportion of cardiac causes in two-year deaths did not differ between the lower and higher BI groups (48.8% vs. 49.5%, P = 0.891). Subgroup analyses consistently demonstrated an association between two-year mortality and lower BI; however, this association was stronger among patients with a higher eGFR (P-value for interaction = 0.004). A lower BI was independently associated with non-home discharge and higher mortality rates because of cardiac- and non-cardiac-related causes in hospitalized patients with HF.

Association between complementary use of Goreisan (a Japanese herbal Kampo medicine) and heart failure readmission: A nationwide propensity score-matched study

BACKGROUND

Goreisan, a Japanese herbal medicine, possesses aquaretic properties to regulate body fluid homeostasis and may therefore be effective as a complement to standard therapy in improving outcomes in patients with heart failure (HF).

METHODS

We retrospectively identified 431,393 patients (mean age 79.2 ± 12.6 years; male 52.3 %) who were admitted for HF for the first time and were discharged alive with standard HF medications between April 2016 and March 2022, using the Japanese Diagnosis Procedure Combination database. We divided patients into two groups according to the prescription of Goreisan at discharge: patients who received standard HF medications plus Goreisan and those who received standard medications alone. We compared the incidence of HF readmission within 1 year after discharge between the groups using propensity score matching.

RESULTS

Overall, Goreisan was prescribed in 1957 (0.45 %) patients at discharge. Patients who received Goreisan were older and received diuretics more frequently than those who did not. One-to-four propensity score matching created a cohort of 1957 and 7828 patients treated with and without Goreisan, respectively. No significant difference was found in the incidence of 1-year HF readmission between the groups [22.1 % vs. 21.7 %; hazard ratio (HR) = 1.02, 95 % confidence interval (CI) = 0.92-1.13]. This result was consistent with that from competing risk analysis (subdistribution HR = 1.02, 95 % CI = 0.92-1.13) and across clinically relevant subgroups except for renal disease. Goreisan use was associated with a lower incidence of HF readmission among patients with renal disease (HR = 0.77, 95 % CI = 0.60-0.97), but not among those without (HR = 1.09, 95 % CI = 0.97-1.23; p for interaction = 0.009).

CONCLUSIONS

This nationwide propensity score-matched analysis did not demonstrate that complementary Goreisan use at discharge was associated with a lower incidence of 1-year HF readmission in patients with HF receiving standard medications. An ongoing randomized trial is awaited to establish the effectiveness of Goreisan use in patients with HF.

Optimizing Guideline-Directed Medical Therapy During Hospitalization Improves Prognosis in Patients With Worsening Heart Failure Requiring Readmissions

BACKGROUND

We previously demonstrated that higher simple guideline-directed medical therapy (GDMT) scores (comprising renin-angiotensin system inhibitors, β-blockers, mineralocorticoid antagonists, and sodium-glucose cotransporter 2 inhibitors) at discharge were correlated with improved prognosis in heart failure (HF) patients. HF readmissions are linked to adverse outcomes, emphasizing the need for enhanced optimization of GDMT.

METHODS AND RESULTS

Using the simple GDMT score, we evaluated the effect of revising and modifying in-hospital GDMT on the prognosis of patients with HF readmissions. In this retrospective analysis of 2,100 HF patients, we concentrated on 1,222 patients with HF with reduced ejection/moderately reduced ejection fraction, excluding patients with HF with preserved ejection fraction, on dialysis, or who died in hospital. A higher current GDMT score was associated with better HF prognosis. Of the 1,222 patients in the study, we analyzed 372 cases of rehospitalization, calculating the simple GDMT scores at admission and discharge. Patients were divided into groups according to score improvement. Multivariate analysis showed a significant association between improved in-hospital simple GDMT score and the composite outcome (HF readmission+all-cause mortality; hazard ratio 0.459; 95% confidence interval 0.257-0.820; P=0.008). Even after propensity score matching to adjust for background, among rehospitalized patients, those with an improved in-hospital simple GDMT score had a better prognosis.

CONCLUSIONS

Our results highlight the potential of robust interventions and score elevation during hospitalization leading to improved outcomes.
