Effect of Optimizing Guideline-Directed Medical Therapy Before Discharge on Mortality and Heart Failure Readmission in Patients Hospitalized With Heart Failure With Reduced Ejection Fraction.

Guideline-directed medical therapy (GDMT) is recommended for patients with heart failure with reduced ejection fraction (HFrEF). However, the prognostic impact of medication optimization at the time of discharge in patients hospitalized with heart failure (HF) is unclear. We analyzed 534 patients (73 ± 13 years old) with HFrEF. The status of GDMT at the time of discharge (prescription of angiotensin converting enzyme inhibitor [ACE-I]/angiotensin receptor blocker [ARB] and β blocker [BB]) and its association with 1-year all-cause mortality and HF readmission were investigated. Patients were divided into 3 groups: those treated with both ACE-I/ARB and BB (Both group: n = 332, 62%), either ACE-I/ARB or BB (Either group: n = 169, 32%), and neither ACE-I/ARB nor BB (None group: n = 33, 6%), respectively. One-year mortality, but not 1-year HF readmission rate, was significantly different in the 3 groups, in favor of the Either and Both groups. A favorable impact of being on GDMT at the time of discharge on 1-year mortality was retained even after adjustment for covariates (Either group: hazard ratio [HR] 0.44, 95% confidence interval [CI] 0.21 to 0.90, p = 0.025 and Both group: HR 0.29, 95% CI 0.13-0.65, p = 0.002, vs None group). For 1-year HF readmission, no such association was found. In conclusion, optimization of GDMT before the time of discharge was associated with a lower 1-year mortality, but not with HF readmission rate, in patients hospitalized with HFrEF.

Discharge treatment with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker after a heart failure hospitalisation is associated with a better prognosis irrespective of left ventricular ejection fraction.

Medical therapy could improve the prognosis of real-life patients discharged after a heart failure (HF) hospitalisation. To determine the impact of discharge HF treatment on mortality and readmissions in different left ventricular ejection fraction (LVEF) groups. Multicentre prospective registry in 20 Spanish hospitals. Patients were enrolled after a HF hospitalisation. A total of 1831 patients was included (583 (31.8%) HF with reduced ejection fraction (HFrEF); 227 (12.4%) HF with midrange ejection fraction (HFmrEF); 610 (33.3%) HF with preserved ejection fraction (HFpEF), and 411 (22.4%) with unknown LVEF). Angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARB) at discharge were independently associated with a reduction in: (i) all-cause mortality: hazard ratio (HR) 0.55, 95% confidence interval (CI) 0.41-0.74, P < 0.001, with a similar effect in the four groups; (ii) mortality due to refractory HF HR 0.45, 95% CI 0.29-0.64, P < 0.001, with a similar effect in the three groups with known LVEF; (iii) mortality/HF admissions (HR 0.61; 95% CI: 0.50-0.74), more evident in HFrEF (HR 0.54; 95% CI: 0.38-0.78) compared with HRmEF (HR 0.64; 95% CI 0.40-1.02), or HFpEF (HR 0.70; 95% CI 0.53-0.92). In patients with HFrEF triple therapy (ACE inhibitor/ARB + beta blocker + mineralocorticoid receptor antagonist) was associated with the lowest mortality risk (HR 0.21; 95% CI: 0.08-0.57, P = 0.002) compared with patients that received none of these drugs. Discharge treatment with ACE inhibitor/ARB after a HF hospitalisation is associated with a reduction in all-cause and refractory HF mortality, irrespective of LVEF.

Effectiveness of guideline-consistent heart failure drug prescriptions at hospital discharge on 1-year mortality: Results from the EPICAL2 cohort study.

We aimed to assess the effectiveness of recommended drug prescriptions at hospital discharge on 1-year mortality in patients with heart failure (HF) and reduced ejection fraction (HFREF). We used data from the EPICAL2 cohort study. HF patients ≥18years old with left ventricular ejection fraction (LVEF) <40% and alive at discharge were included and followed up for mortality. Socio-demographic, clinical and therapeutic data were collected at admission. Therapeutic data were collected at discharge and at 6month. Prescription of an angiotensin-converting enzyme (ACE) inhibitor (or an angiotensin II receptor blocker [ARB] in case of ACE inhibitor intolerance) and a β-blocker at discharge were considered "guideline-consistent discharge prescription" (GCDP). A frailty Cox model after propensity score (PS) matching was used to assess the association of GCDP with survival. Among 624 patients included, the mean (SD) age was 73.6 (12.8) years; 65% were male. A total of 412 (65.6%) patients received GCDP, and 82.8% still had guideline consistent prescription at 6months. A total of 166 patients died during the follow-up, 78 in the GCDP group and 88 in the other group. Before PS matching, patients with GCDP were younger (|StDiff|=48.32%) and had higher body mass index (BMI) (|StDiff|=11.71%), lower LVEF (|StDiff|=23.13%) and lower Charlson index (|StDiff|=55.27%) than patients without GCDP. After PS matching, all characteristics were balanced between the two treatment groups, and GCDP was associated with reduced mortality (pooled HR=0.51, 95% CI [0.35-0.73]). Prescription of ACE (or ARB) inhibitors and β-blockers for patients with HFREF may be low despite the evidence for morbidity and mortality improvement with these medications but remains associated with reduced 1-year mortality in unselected HFREF patients.

Prescribing patterns of evidence-based heart failure pharmacotherapy and outcomes in the ASIAN-HF registry: a cohort study.

Angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), β blockers, and mineralocorticoid receptor antagonists (MRAs) are of proven benefit and are recommended by guidelines for management of patients with heart failure and reduced ejection fraction (HFrEF). We aimed to examine the first prospective multinational data from Asia on prescribing patterns of guideline-directed medical therapies and analyse its effect on outcomes. In the prospective multinational ASIAN-HF registry (with enrolment from 46 centres in 11 countries in Asia), we enrolled patients aged 18 years or older, with symptomatic heart failure (stage C, with at least one episode of decompensated heart failure in the past 6 months that resulted in admission to hospital or was treated in an outpatient clinic) and left ventricular systolic dysfunction (ejection fraction ≤40% on baseline echocardiography, consistent with 2016 European Society of Cardiology guidelines). We excluded patients with heart failure caused by severe valvular heart disease, life-threatening comorbidity with a life expectancy of less than 1 year, who were unable or unwilling to give consent, or who had concurrent participation in a clinical trial. Patients were followed up for 3 years for the outcomes of death and cause-specific admittance to hospital. Primary outcomes were uptake of guideline-directed medical therapies (as proportions) by therapeutic class, achieved doses as proportions of guideline-recommended doses, and their association with 1-year composite outcome of all-cause death or admittance to hospital because of heart failure. This study is registered with ClinicalTrials.gov, number NCT01633398. Between Oct 1, 2012, and Dec 31, 2015, we enrolled 5276 patients with HFrEF (mean age 59·6 years [SD 13·2], 77% men, body-mass index 24·9 kg/m2 [5·1], 33% New York Heart Association class III or IV). Follow-up data were available for 4544 (90%) of 5061 eligible patients taking medication for heart failure, with median follow-up of 417 days (IQR 214-735). ACE inhibitors or ARBs were prescribed to 3868 (77%) of 5005 patients, β blockers to 3975 (79%) of 5061, and MRAs to 2998 (58%) of 5205, with substantial regional variation. Guideline-recommended dose was achieved in only 17% of cases for ACE inhibitors or ARB, 13% for β blockers, and 29% for MRAs. Country (all three drug classes), increasing body-mass index (ACE inhibitors or ARBs and MRAs), and in-patient recruitment (ACE inhibitors or ARBs and β blockers) were associated with attainment of guideline-recommended dose (all p<0·05). When adjusted for indication bias, increasing drug doses, from low dose (1-<25% of guideline-recommended dose) upwards were associated with lower hazards of a 1-year composite outcome for ACE inhibitors or ARBs and β blockers compared with non-users. The lowest adjusted hazards were in the group that attained guideline-recommended doses above 50% (hazard ratio [HR] 0·54, 95% CI 0·50-0·58 for ACE inhibitors or ARBs [50-99·9%]; HR 0·47, 0·46-0·50 for β blockers, and HR 0·77, 0·72-0·81 for MRAs [≥100%]). Guideline-directed medical therapies at recommended doses are underutilised in patients with HFrEF. Improved uptake and uptitration of guideline-directed medical therapies are needed for better patient outcomes.

Assessing Guideline-Directed Medication Therapy for Heart Failure in End-Stage Renal Disease.

Treatment of heart failure with reduced ejection fraction (HFrEF) requires guideline-directed medication therapy (GDMT) consisting of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker in combination with an indicated beta-blocker. There is concern that end-stage renal disease (ESRD) patients are not being prescribed GDMT. The study aim was to determine whether outcomes differ for patients with HFrEF and ESRD receiving GDMT compared to those not receiving GDMT. Adult patients with ESRD and HFrEF admitted to a tertiary teaching hospital over a 2-year period were included. Patients were categorized into GDMT or non-GDMT groups based on their home medications. The length of stay (LOS), mortality, and 30-day hospital readmissions were compared between groups. The incidence of hyperkalemia, hypotension and bradycardia were also evaluated. A total of 109 patients were included: 88% African-American, 61% males, median age 63 (28-93) years with 25 in the GDMT group and 84 in the non-GDMT group. The LOS did not differ between the GDMT (5 days; 3-14) compared to the non-GDMT group (7 days; 3-28), P = 0.14. Thirty-day hospital readmission and in-hospital mortality were also similar. Hypotension occurred less frequently in the GDMT group compared to the non-GDMT group, 4% versus 27% (P = 0.01). Although there were no differences in the primary outcomes, the shorter LOS in the GDMT group may be clinically significant. The fact that most patients with ESRD and HFrEF were not receiving GDMT is a finding that requires further evaluation.
