Background: Outcomes of hospitalized patients with heart failure (HF) and characteristics of advanced HF stage may vary across left ventricular ejection fraction (LVEF) and world regions.

Objectives: This study sought to analyze characteristics of hospitalized advanced HF patients across LVEF spectrum, world regions, and country income.

Methods: Among 18,553 hospitalized patients with acute HF (7,902 new-onset HF and 10,651 decompensated chronic HF) enrolled in the global registry REPORT-HF (International Registry to Assess Medical Practice With Longitudinal Observation for Treatment of Heart Failure), we analyzed characteristics and outcomes of patients with advanced HF, defined as previously diagnosed HF; severe symptoms before current admission (NYHA functional class III/IV); and ≥1 HF-related hospitalization in the preceding 12 months, excluding the current. Differences among hospitalized advanced HF subgroups stratified by LVEF, world region, and country income were examined.

Results: Among 6,999 patients with decompensated chronic HF and available previous NYHA functional class and HF hospitalization status, 3,397 (48.5%; 18.3% of the total population) had advanced HF. Of these, 44.5% had severely reduced (≤30%), 34.9% mildly/moderately reduced (31%-49%), and 20.7% preserved (≥50%) LVEF. Patients from Eastern Europe had the lowest 1-year mortality (23%), whereas those from Southeast Asia had the highest (37%). Patients from lower-middle-income countries were younger, with shorter HF duration and lower comorbidity prevalence, received fewer beta-blockers and HF-devices, and had higher 1-year mortality (34%) than upper-middle- (26%) or high-income countries (27%; P = 0.018). Adjusted 1-year mortality risk did not differ among LVEF subgroups (all P > 0.05), nor did 1-year HF hospitalization rate (P = 0.56).

Conclusions: Hospitalized patients with advanced HF and preserved LVEF had similarly adverse outcomes as those with reduced LVEF. Patients from lower-middle-income countries had less implementation of HF therapies and higher 1-year mortality.

Background: An improved understanding of the natural history in NYHA functional class I patients with obstructive hypertrophic cardiomyopathy (oHCM) is needed.

Objectives: Using a multicenter registry (SHaRe [Sarcomeric Human Cardiomyopathy Registry]), this study described the natural history in patients with oHCM who were classified as NYHA functional class I at the initial visit compared with patients classified as NYHA functional class II and reported baseline characteristics associated with incident clinical events.

Methods: Incident events assessed included a composite of NYHA functional class III to IV symptoms, left ventricular ejection fraction <50%, atrial fibrillation, stroke, ventricular arrhythmias, septal reduction therapy, ventricular assist device or transplantation, or death. Factors associated with incident events were determined using Kaplan-Meier, Cox proportional hazards, and restricted cubic spline models.

Results: Of 7,964 patients with HCM in SHaRe, 1,239 patients with oHCM met inclusion criteria; 598 were in NYHA functional class I at the initial visit (age 48 ± 17 years; 31.1% female; peak gradient, 75 ± 40 mm Hg). At 5-year follow-up, the composite event rate of NYHA functional class I patients was 28% compared with 44% (P < 0.001) in 641 NYHA functional class II patients with oHCM (age 54 ± 16 years; 46.5% female; peak gradient, 83 ± 39 mm Hg). Left atrial (LA) diameter ≥45 mm (HR: 1.56 [95% CI: 1.14-2.12]; P = 0.005), female sex (HR: 1.61 [95% CI: 1.16-2.24]; P = 0.003), and older age (HR: 1.21 per 10 years [95% CI: 1.09-1.34]; P < 0.001), but not the magnitude of left ventricular outflow tract obstruction, were associated with a higher risk of the composite outcome in NYHA functional class I patients.

Conclusions: Although NYHA functional class I patients with oHCM fared better than NYHA functional class II patients, more than one-fourth experienced adverse events over 5-year follow-up, especially if they were older, female, and/or had LA enlargement. Strategies to reduce the rate of clinical outcomes in NYHA functional class I patients warrant further study.

Heart failure (HF) is a leading cause of cardiovascular morbidity, mortality, and health care expenditure. Guideline-directed medical therapy and device-based therapy in HF are well established. However, the role of nonpharmacologic modalities to improve HF care remains underappreciated, is underused, and requires multimodal approaches to care. Diet, exercise and cardiac rehabilitation, sleep-disordered breathing, mood disorders, and substance use disorders are potential targets to reduce morbidity and improve function of patients with HF. Addressing these factors may improve symptoms and quality of life, reduce hospitalizations, and improve mortality in heart failure. This state-of-the-art review discusses dietary interventions, exercise programs, and the management of sleep-disordered breathing, mood disorders, and substance use in individuals with heart failure. The authors review the latest data and provide optimal lifestyle recommendations and recommended prescriptions for nonpharmacologic therapies.

Background: Although clinical evidence supports rapid institution of guideline-directed medical therapy (GDMT) for heart failure (HF), in actual practice, there remain large gaps in adherence to guideline recommendations. Recent data support safety and efficacy of rapid GDMT implementation; however, rapid GDMT deployment within a general cardiology environment remains unexplored.

Objectives: The purpose of this study was to evaluate the efficacy and safety of a GDMT clinic within a general cardiology practice relative to usual care, the impact on prescription of GDMT, HF symptoms, N-terminal pro-B-type natriuretic peptide concentrations and echocardiographic parameters of remodeling.

Methods: Individuals with HF with an abnormal ejection fraction (<50%) referred to the GDMT clinic underwent rapid GDMT titration with close monitoring of clinical data. Rates of GDMT prescription were compared with a matched reference group. Patients underwent echocardiography at baseline and after GDMT clinic completion.

Results: A total of 114 persons were treated in GDMT clinic. The mean age was 67.6 ± 14.6 years, and 32 (28%) were women. Among those referred, 100 (87.7%) had no contraindications for 4-drug GDMT. From baseline to clinic completion (median 15.8 weeks [Q1-Q3: 10.7-23.0 weeks]), patients without medication contraindications experienced significant increases in 4-drug GDMT use (from 21% to 88%; P < 0.001); of 4-drug GDMT recipients, 92% received angiotensin receptor neprilysin inhibitor. GDMT clinic participants achieved higher medication doses than those in usual care, with greater achievement of ≥50% target dose of angiotensin receptor neprilysin inhibitor (52% vs 8%), beta-blocker (78% vs 6.2%), mineralocorticoid receptor antagonist (98% vs 15.6%), and sodium-glucose cotransporter 2 inhibitors (92% vs 6.2%). Target doses of all 4 drugs were reached in nearly 1 in 4 participants. HF symptoms improved (94% to 75% NYHA functional class II/III; P < 0.001) and N-terminal pro-B-type natriuretic peptide concentration decreased (median 587 to 534 ng/L; P = 0.03) despite loop diuretic reduction. Additionally, we observed an absolute 6% LVEF increase (from 37% [Q1-Q3: 31%-41%] to 43% [Q1-Q3: 38%-53%]; P < 0.001) and substantial decrease in moderate or severe mitral regurgitation. GDMT titration was well-tolerated.

Conclusions: Rapid GDMT implementation via an outpatient GDMT clinic was effective, safe, and associated with improvement in key clinical parameters. The more widespread role of GDMT clinics to improve HF care warrants further study.
