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, ß-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.

A scoring evaluation for the practical introduction of guideline-directed medical therapy in heart failure patients.

AIMS: The guideline-directed medical therapy (GDMT) has been recommended for heart failure (HF) with reduced ejection fraction (HFrEF) based on the accumulating clinical evidence. However, it is difficult to implement all the trial-proven medications for every patient in the real world. METHODS AND RESULTS: A simple GDMT score was created, according to the combination of GDMT drugs (renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose transporter 2 inhibitors) administration and their dosage (0-9 points). Its impact on the prognosis of HF patients was investigated. Admitted HF patients [HFrEF and HF with mildly reduced ejection fraction (HFmrEF), n = 1054] were retrospectively analysed (excluding those with in-hospital death and dialysis). A simple GDMT score ≥5, but not the number of medications, was significantly associated with a reduction of all-cause death, HF readmission, and composite outcome (HF readmission and all-cause death) (P < 0.001). Subgroup analysis showed that almost all groups with a simple GDMT score of 5 or higher had a better prognosis. CONCLUSIONS: The developed simple GDMT score was associated with prognosis in HFrEF and HFmrEF patients. Even if all four drugs cannot be introduced for some reason, a regimen with a simple GDMT score ≥5 may lead to a prognosis in HF patients.

Early Initiation of Sodium-Glucose Cotransporter 2 Inhibitor Leads to a Shorter Hospital Stay in Patients With Acute Decompensated Heart Failure.

Background: The efficacy of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with acute chronic heart failure (HF) is increasingly being reported. However, it is not clear when SGLT2i should be initiated in patients with acute decompensated HF (ADHF) after hospitalization. We retrospectively analyzed ADHF patients with newly prescribed SGLT2i. Methods and Results: Among the 694 patients hospitalized due to HF between May 2019 and May 2022, data were extracted for 168 patients with newly prescribed SGLT2i during the index hospitalization. These patients were divided into 2 groups: and early group (92 patients who started SGLT2i within 2 days of admission) and a late group (76 patients who started SGLT2i after 3 days). Clinical characteristics were comparable between the 2 groups. The date of cardiac rehabilitation initiation was significantly earlier in the early than late group (2.5±1.2 vs. 3.8±2.2 days; P<0.001). Hospital stay was significantly shorter in the early group (16.4±6.5 vs. 24.2±16.0 days; P<0.001). Although there were significantly fewer HF readmissions within 3 months in the early group (2.1% vs. 10.5%; P=0.044), the association disappeared in a multivariate analysis including clinical confounders. Conclusions: Early initiation of SGLT2i may shorten hospital stays.

Use of a Cutting Balloon Reduces the Incidence of Distal Embolism in Acute Coronary Syndrome Requiring Predilatation Before Stenting.

Background: Acute coronary syndrome (ACS) patients with solid lesions often require predilatation before stenting. Predilatation with high pressure may increase the risk of distal embolism, whereas direct stenting increases the risk of stent underexpansion. We recently reported that, in severely calcified lesions, using a cutting balloon (CB) can provide greater acute gain compared with other scoring balloons. Therefore, we hypothesized that predilatation with CB may reduce the incidence of distal embolism in ACS patients with solid lesions. Methods and Results: This study retrospectively analyzed data for 175 ACS patients who required predilatation, either with a conventional balloon (n=136) or CB (n=39). The occurrence of distal embolism was significantly lower in the CB than conventional balloon group (10.3% vs 32.4%, respectively; P=0.007). Multivariate analysis showed that the occurrence of distal embolism was positively associated with Thrombolysis in Myocardial Infarction (TIMI) grade and the presence of attenuated plaque, but negatively associated with the use of a CB. To support this clinical observation, we compared thrombus dispersal using a CB and non-compliant balloon in an ex vivo experimental model using a pseudo-thrombus. In this model, pseudo-thrombus dispersal was significantly smaller when a CB rather than non-compliant balloon was used (1.8±1.0% vs 2.6±1.2%, respectively; n=20, for each; P=0.002). Conclusions: In ACS patients with solid lesions that require predilatation, predilatation with a CB may reduce the incidence of distal embolism.

Early follow-up at outpatient care after discharge improves long-term heart failure readmission rate and prognosis.

AIMS: It has been reported that congestive heart failure (CHF) readmission has not decreased in the last decade. It is also reported that CHF readmission is likely to occur shortly after discharge. We investigated whether an early follow-up at outpatient care within 2 weeks after discharge affects the long-term readmission rate and prognosis. METHODS AND RESULTS: We reviewed consecutive 1002 patients admitted to our hospital due to CHF. Two-hundred and fifty-nine patients who died in-hospital or were transferred to another hospital or readmitted within 2 weeks were excluded and 743 of discharged patients were analysed. We extracted contributing variables associated with heart failure (HF) readmission and the composite adverse outcome (all cause death or HF readmissions) by univariate and multivariate analysis. Multivariate analysis showed that the early follow-up was independently associated with freedom from HF readmission and the composite outcome. We divided these patients into two groups, with/without early follow-up and performed a propensity score-matching analysis (n = 259 each). HF readmission during 2 year follow-up was significantly less in the early follow-up group [P = 0.02, hazard ratio (HR) = 0.647, 95% confidence interval (CI) = 0.447-0.935] as well as the composite outcome was less in the early follow-up group (P = 0.01, HR = 0.643, 95% CI = 0.456-0.908). Medication adjustments were done in only 33.2% of the patients. Rates of HF readmissions were comparable regardless of whether or not medication adjustment was done at the early follow-up (P = 0.505, HR = 1.208, 95% CI = 0.692-2.106). CONCLUSIONS: The present study demonstrates that an early follow-up approach after discharge in CHF patients may improve the long-term prognosis. These results may not depend on medication adjustment but rather on modifying patient factors early after discharge.
