Background: Many patients with heart failure and preserved ejection fraction have no overt volume overload and normal resting left atrial (LA) pressure., Objectives: This study sought to characterize patients with normal resting LA pressure (pulmonary capillary wedge pressure [PCWP] <15 mm Hg) but exercise-induced left atrial hypertension (EILAH)., Methods: The REDUCE LAP-HF II (A Study to Evaluate the Corvia Medical, Inc. IASD System II to Reduce Elevated Left Atrial Pressure in Patients With Heart Failure) trial randomized 626 patients with ejection fraction ≥40% and exercise PCWP ≥25 mm Hg to atrial shunt or sham procedure. The primary trial outcome, a hierarchical composite of death, heart failure hospitalization, intensification of diuretics, and change in health status was compared between patients with EILAH and those with heart failure and resting left atrial hypertension (RELAH)., Results: Patients with EILAH (29%) had similar symptom severity, but lower natriuretic peptide levels, higher 6-minute walk distance, less atrial fibrillation, lower left ventricular mass, smaller LA volumes, lower E/e', and better LA strain. PCWP was lower at rest, but had a larger increase with exercise in EILAH. Neither group as a whole had a significant effect from shunt therapy vs sham. Patients with EILAH were more likely to have characteristics associated with atrial shunt responsiveness (peak exercise pulmonary vascular resistance <1.74 WU) and no pacemaker (63% vs 46%; P < 0.001). The win ratio for the primary outcome was 1.56 (P = 0.08) in patients with EILAH and 1.51 (P = 0.04) in those with RELAH when responder characteristics were present., Conclusions: Patients with EILAH had similar symptom severity but less advanced myocardial and pulmonary vascular disease. This important subgroup may be difficult to diagnose without invasive exercise hemodynamics, but it has characteristics associated with favorable response to atrial shunt therapy.

Objectives: The purpose of this study was to evaluate the relationship between calorie intake and post-discharge outcomes in hospitalized patients with heart failure (HF)., Background: Malnutrition increases adverse outcomes in HF, and dietary sodium restriction may inadvertently worsen nutritional intake., Methods: In a dietary intervention trial, baseline nutritional intake in HF inpatients was estimated using the Block Food Frequency Questionnaire (FFQ), and the Nutritional Risk Index (NRI) was calculated. Insufficient calorie intake was defined as <90% of metabolic needs, and a 15-point micronutrient deficiency score was created. Adjusted linear, logistic, and negative binomial regression were used to evaluate associations between insufficient calorie intake and quality of life (using the Kansas City Cardiomyopathy Questionnaire Clinical Summary [KCCQ-CS]), readmission risk, and days rehospitalized over 12 weeks., Results: Among 57 participants (70 ± 8 years of age; 31% female; mean body mass index 32 ± 8 kg/m 2 ); median sodium and calorie intake amounts were 2,987 mg/day (interquartile range [IQR]: 2,160 to 3,540 mg/day) and 1,602 kcal/day (IQR: 1,201 to 2,142 kcal/day), respectively; 11% of these patients were screened as malnourished by the NRI. All patients consuming <2,000 mg/day sodium had insufficient calorie intake; this group also more frequently had dietary micronutrient and protein deficiencies. At 12 weeks, patients with insufficient calorie intake had less improvement in the KCCQ-CS score (β = -14.6; 95% confidence interval [CI]: -27.3 to -1.9), higher odds of readmission (odds ratio: 14.5; 95% CI: 2.2 to 94.4), and more days rehospitalized (incident rate ratio: 31.3; 95% CI: 4.3 to 229.3)., Conclusions: Despite a high prevalence for obesity and rare overt malnutrition, insufficient calorie intake was associated with poorer post-discharge quality of life and increased burden of readmission in patients with HF. Inpatient dietary assessment could improve readmission risk stratification and identify patients for nutritional intervention.

Objectives: This study identified sociodemographic and clinical factors that predicted live discharge among home hospice patients with heart failure, and related these findings to perspectives among health care providers about challenges to caring for these patients., Background: Hospice patients with heart failure are frequently discharged from hospice before death ("live discharge"). However, little is known about the factors and circumstances associated with live discharge among patients with heart failure., Methods: Quantitative analyses of patient medical records (N = 1,498) and qualitative interviews were performed with health care providers (n = 19) at a not-for-profit hospice agency in New York City., Results: Thirty percent of home hospice patients with heart failure experienced a live discharge, most frequently due to 911 calls that led to acute hospitalization. The odds of acute hospitalization were higher for younger patients (age 18 to 74 years: adjusted odds ratio [AOR]: 2.10; 95% confidence interval [CI]: 1.34 to 3.28), African American (AOR: 2.06; 95% CI: 1.31 to 3.24) or Hispanic (AOR: 2.99; 95% CI: 1.99 to 4.50) patients, and higher functioning patients (Palliative Performance Scores of 50% to 70%; AOR: 5.68; 95% CI: 3.66 to 8.79). Qualitative interviews with health care providers highlighted the unique characteristics of heart failure (e.g., sudden changes in patients' condition), the importance of patients' understanding of hospice and their own prognosis, and the role of sociocultural and family context in precipitating and potentially preventing live discharge (e.g., absence of social supports in the home)., Conclusions: Live discharge from hospice, especially due to acute hospitalization, is common with heart failure. Greater attention is needed for patients' knowledge of and readiness for hospice care, especially among younger and diverse populations, and for factors related to the social and family context in which hospice care is provided., (Copyright © 2019 American College of Cardiology Foundation.

Objectives: The objective of this study was to evaluate an interhospital collaborative approach to improve 7-day post-discharge follow-up (7dFU) rates and reduce 30-day readmissions in heart failure (HF) patients., Background: Early post-discharge follow-up after HF hospitalization is associated with lower 30-day readmission rates., Methods: Observational analyses of Medicare HF patients discharged from 10 collaborating hospitals (CH) participating in the Southeast Michigan See You in 7 Collaborative were carried out. We compared pre-intervention (May 1, 2011 to April 30, 2012) and intervention (May 1, 2012 to April 30, 2013) 7dFU rates, unadjusted 30-day readmissions, risk-standardized 30-day readmissions (RSRR), and Medicare payments in CH and Michigan nonparticipating hospitals (NPH)., Results: 7dFU rates increased but remained low in both groups (CH: 31.1% to 34.4%; p < 0.001; NPH: 30.2% to 32.6%; p <0.001). During the intervention period, unadjusted readmissions decreased significantly in both groups (CH: 29.0% to 27.3%; p <0.001; NPH: 26.4% to 25.8%, p = 0.004); mean RSRR decreased more in CH than in NPH (CH: 31.1% to 28.5%; p < 0.001; NPH: 26.7% to 26.1%, p = 0.02; p = 0.015 for intergroup comparisons). Findings were similar when CH outcomes were matched 1:1 with similar NPH outcomes. Combined Medicare payments for inpatient and 30 days of post-discharge care decreased by $182 in CH and by $63 in NPH (per eligible HF discharge)., Conclusions: See You in 7 Collaborative participation was associated with significantly lower 30-day readmissions and Medicare payments in HF patients. Increases in 7dFU were modest, but associated processes aimed at this goal may have improved the transition from inpatient to outpatient care. Regional hospital collaboration to share best practices could potentially reduce HF readmissions and associated costs., (Copyright © 2015 American College of Cardiology Foundation.
