Does an Intervention Designed to Improve Self-management, Social Support and Awareness of Palliative-care Address Needs of Persons with Heart Failure, Family Caregivers and Clinicians?

Aims and Objectives To conduct a formative evaluation of the iPad‐Enhanced Shared Care Intervention for Partners (iSCIP) among persons with heart failure (HF), family caregivers and clinicians. Together, persons with HF and family caregivers are referred to as partners. Background There is growing awareness of the caregiver\u27s contributions to HF self‐management, social support and reciprocal benefits of interventions that involve both partners. The iSCIP engages both partners in a six‐session psychosocial intervention to address three preventable causes of poor outcomes in a HF population: poor self‐management skills, inadequate social support and underutilisation of palliative care. An iPad app is used to organise the intervention. The goals of the iSCIP are to engage partners in HF self‐management, communication about the HF patient\u27s care values and preferences, and future planning. Design A qualitative focus group design was used. Methods Seven clinicians and eight partners participated in focus groups to explore their experiences, needs and reaction to the iSCIP content and technologies employed. Open‐ended questions and closed‐ended surveys were used to collect data. Deductive content analysis was used to analyse the qualitative data. NVivo software was used for qualitative data analysis. Bayesian statistical models were used to analyse numeric data. Results The iSCIP met partners’ and clinicians’ needs to improve self‐management, communicate about care values and preferences and plan for the future. Quantitative analysis of numeric data supported our qualitative findings, in that both groups rated the intervention components useful to very useful. Implications for practice These findings add to the growing evidence of the feasibility and acceptability of programs that address care values and preferences, and care planning. The iSCIP can be used as a guide for developing interventions and software applications, which involve both partners in care and palliative‐care discussions

Favorable Outcomes of LVAD as Bridge to Simultaneous Heart-Kidney Transplantation

Background Chronic kidney disease (CKD) is an established risk factor for incident cardiovascular disease and progression of heart failure disease state, and is associated with decreased survival after left ventricular assist device (LVAD) therapy or heart transplantation (HT). Combined heart-kidney transplantation (HKT) compared with isolated HT recently has been shown to have survival advantage among patients whose estimated glomerular filtration rate is less than 37 ml/min/m2. Data on LVAD to HKT are limited. Methods At our center, a total of 803 patients have received HT, 594 patients LVAD therapy, and 23 patients HKT from single donors; of those 23, 15 were without the use of LVAD and 8 were after support with LVAD. Results Kaplan-Meier survival analysis found LVAD-supported patients with CKD stages 4 or 5 had statistically worse 24-month survival after HT as compared with those with CKD stage 1, 2, and 3 (58% vs 88%, p=0.01). Patients who received combined HKT after LVAD had comparable 24-month survival with those who received HKT without LVAD (87% and 85%, p=NS); both groups had numerically better survival compared with those who had CKD (stage 4-5) with isolated HT (58%). Conclusions Patients supported with LVAD who demonstrate advanced CKD (stage 4-5) have worse 24-month post-HT survival compared with those with less advanced CKD (stage 1-3). Combined HKT after LVAD support is feasible and confers comparable 24-month survival compared with HKT without prior LVAD therapy. Our study supports combined HKT for select LVAD patients with advanced CKD (stage 4-5)

A principal components analysis of factors associated with successful implementation of an LVAD decision support tool

Background A central goal among researchers and policy makers seeking to implement clinical interventions is to identify key facilitators and barriers that contribute to implementation success. Despite calls from a number of scholars, empirical insights into the complex structural and cultural predictors of why decision aids (DAs) become routinely embedded in health care settings remains limited and highly variable across implementation contexts. Methods We examined associations between “reach”, a widely used indicator (from the RE-AIM model) of implementation success, and multi-level site characteristics of nine LVAD clinics engaged over 18 months in implementation and dissemination of a decision aid for left ventricular assist device (LVAD) treatment. Based on data collected from nurse coordinators, we explored factors at the level of the organization (e.g. patient volume), patient population (e.g. health literacy; average sickness level), clinician characteristics (e.g. attitudes towards decision aid; readiness for change) and process (how the aid was administered). We generated descriptive statistics for each site and calculated zero-order correlations (Pearson’s r) between all multi-level site variables including cumulative reach at 12 months and 18 months for all sites. We used principal components analysis (PCA) to examine any latent factors governing relationships between and among all site characteristics, including reach. Results We observed strongest inclines in reach of our decision aid across the first year, with uptake fluctuating over the second year. Average reach across sites was 63% (s.d. = 19.56) at 12 months and 66% (s.d. = 19.39) at 18 months. Our PCA revealed that site characteristics positively associated with reach on two distinct dimensions, including a first dimension reflecting greater organizational infrastructure and standardization (characteristic of larger, more established clinics) and a second dimension reflecting positive attitudinal orientations, specifically, openness and capacity to give and receive decision support among coordinators and patients. Conclusions Successful implementation plans should incorporate specific efforts to promote supportive and mutually informative interactions between clinical staff members and to institute systematic and standardized protocols to enhance the availability, convenience and salience of intervention tool in routine practice. Further research is needed to understand whether “core predictors” of success vary across different intervention types

Regulation of Coronary Blood Flow

The heart is uniquely responsible for providing its own blood supply through the coronary circulation. Regulation of coronary blood flow is quite complex and, after over 100 years of dedicated research, is understood to be dictated through multiple mechanisms that include extravascular compressive forces (tissue pressure), coronary perfusion pressure, myogenic, local metabolic, endothelial as well as neural and hormonal influences. While each of these determinants can have profound influence over myocardial perfusion, largely through effects on end-effector ion channels, these mechanisms collectively modulate coronary vascular resistance and act to ensure that the myocardial requirements for oxygen and substrates are adequately provided by the coronary circulation. The purpose of this series of Comprehensive Physiology is to highlight current knowledge regarding the physiologic regulation of coronary blood flow, with emphasis on functional anatomy and the interplay between the physical and biological determinants of myocardial oxygen delivery. © 2017 American Physiological Society.

Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTIC‐HF: baseline characteristics and comparison with contemporary clinical trials

Aims: The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC‐HF) trial. Here we describe the baseline characteristics of participants in GALACTIC‐HF and how these compare with other contemporary trials. Methods and Results: Adults with established HFrEF, New York Heart Association functional class (NYHA) ≥ II, EF ≤35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic‐guided dosing: 25, 37.5 or 50 mg bid). 8256 patients [male (79%), non‐white (22%), mean age 65 years] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NT‐proBNP 1971 pg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTIC‐HF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure < 100 mmHg (n = 1127), estimated glomerular filtration rate < 30 mL/min/1.73 m2 (n = 528), and treated with sacubitril‐valsartan at baseline (n = 1594). Conclusions: GALACTIC‐HF enrolled a well‐treated, high‐risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation

Validation of the Heart QoL Health-Related Quality of Life Questionnaire in Patients with Chronic Ischemic Cardiomyopathy

Objective: The English HeartQoL health-related quality of life questionnaire has been validated in patients with angina and myocardial infarction living in the USA but not in patients with symptomatic heart failure. The factor structure, reliability, validity and responsiveness of the English HeartQoL was assessed in patients with heart failure due to chronic ischemic cardiomyopathy. Methods: A battery of five questionnaires, including the HeartQoL with a Global scale and Physical and Emotional subscales, was self-administered by 90 patients with chronic ischemic cardiomyopathy in Wisconsin, USA, and the HeartQoL factor structure, reliability and validity were assessed. Responsiveness was examined in a separate cohort of 20 patients undergoing cardiac resynchronization therapy. Results: The 2-factor HeartQoL structure was confirmed. Internal consistency reliability was strong with Cronbach’s α ≥0.88. Convergent validity correlations between similar HeartQoL and Minnesota Living with Heart Failure questionnaire (r=-0.81 to -0.82) and Short Form 36 Health Survey constructs (r=0.74 to 0.78) were strong with significantly weaker correlations between dissimilar constructs. Discriminative validity was confirmed on eight of the 10 a priori hypotheses. Over a 3-month period, responsiveness (minimal important difference and effect size) was confirmed on the HeartQoL Global scale and Physical subscale. Conclusion: The English HeartQoL is a reliable, valid and responsive health-related quality of life questionnaire in patients with symptomatic heart failure due to chronic ischemic cardiomyopathy. The English HeartQoL can be recommended as a core heart disease health-related quality of life questionnaire within and across patients with angina, myocardial infarction or heart failure.</jats:p
