Basal Segmental Longitudinal Strain: A Marker of Subclinical Myocardial Involvement in Anderson-Fabry Disease.

BACKGROUND: Cardiac involvement in Anderson-Fabry disease (AFD) is associated with increased left ventricular (LV) wall thickness. The aim of this study was to evaluate if two-dimensional global and regional strain in patients with AFD can identify early myocardial involvement (when LV wall thickness and function are normal). Additionally, the association of altered strain with adverse cardiovascular events was evaluated. METHODS: In a retrospective cross-sectional study, 43 patients with AFD, before enzyme replacement therapy (mean age, 44 ± 12 years; 58.1% men), were compared with age- and gender-matched healthy control subjects. The mean follow-up duration among patients with AFD for major adverse cardiovascular events (MACE) was 82 months. RESULTS: LV ejection fraction was similar between groups (patients with AFD vs control subjects, 61 ± 8% vs 61 ± 6%; P = .89). However, global longitudinal strain (LS) was impaired in patients with AFD compared with control subjects (-16.5 ± 3.8% vs -20.2 ± 1.7%, P < .001), with greater impairment in patients with AFD with increased LV wall thickness (-15.4 ± 3.9% vs -18.7 ± 2.3%, P < .006). Additionally, LS was most impaired in the basal segments in patients with AFD (-14.8 ± 3.7% vs -20.3 ± 1.1%, P < .001). MACE occurred in 19 of 43 patients (four women, 15 men), and Kaplan-Meier analysis demonstrated that MACE were associated with impaired basal LS. CONCLUSIONS: In patients with AFD, altered basal LS is present even in those with normal LV wall thickness and is associated with MACE. Therefore, basal LS should be considered when screening for cardiac involvement in AFD, particularly in female patients with AFD with normal LV wall thickness.

Addition of Supervised Exercise Training to a Post-Hospital Disease Management Program for Patients Recently Hospitalized With Acute Heart Failure: The EJECTION-HF Randomized Phase 4 Trial.

OBJECTIVES: This study sought to measure the impact on all-cause death or readmission of adding center-based exercise training (ET) to disease management programs for patients with a recent acute heart failure (HF) hospitalization. BACKGROUND: ET is recommended for patients with HF, but evidence is based mainly on ET as a single intervention in stable outpatients. METHODS: A randomized, controlled trial with blinded outcome assessor, enrolling adult participants with HF discharged from 5 hospitals in Queensland, Australia. All participants received HF-disease management program plus supported home exercise program; intervention participants were offered 24 weeks of supervised center-based ET. Primary outcome was all-cause 12-month death or readmission. Pre-planned subgroups included age (<70 years vs. older), sex, left ventricular ejection fraction (≤40% vs. >40%), and exercise adherence. RESULTS: Between May 2008 and July 2013, 278 participants (140 intervention, 138 control) were enrolled: 98 (35.3%) age ≥70 years, 71 (25.5%) females, and 62 (23.3%) with a left ventricular ejection fraction of >40%. There were no adverse events associated with ET. There was no difference in primary outcome between groups (84 of 140 [60.0%] intervention vs. 90 of 138 [65.2%] control; p = 0.37), but a trend toward greater benefit in participants age <70 years (OR: 0.56 [95% CI: 0.30 to 1.02] vs. OR: 1.56 [95% CI: 0.67 to 3.64]; p for interaction = 0.05). Participants who exercised to guidelines (72 of 101 control and 92 of 117 intervention at 3 months) had a significantly lower rate of death and readmission (91 of 164 [55.5%] vs. 41 of 54 [75.9%]; p = 0.008). CONCLUSIONS: Supervised center-based ET was a safe, feasible addition to disease management programs with supported home exercise in patients recently hospitalized with acute HF, but did not reduce combined end-point of death or readmission. (A supervised exercise programme following hospitalisation for heart failure: does it add to disease management?; ACTRN12608000263392).

Exploring beliefs about heart failure treatment in adherent and nonadherent patients: use of the repertory grid technique.

PURPOSE: Beliefs about medicines impact on adherence, but eliciting core beliefs about medicines in individual patients is difficult. One method that has the potential to elicit individual core beliefs is the "repertory grid technique." This study utilized the repertory grid technique to elicit individuals' beliefs about their heart failure treatment and to investigate whether generated constructs were different between adherent and nonadherent patients. METHODS: Ninety-two patients with heart failure were interviewed using a structured questionnaire that applied the repertory grid technique. Patients were asked to compare and contrast their medicines and self-care activities for their heart failure. This lead to the generation of individual constructs (perceptions towards medicines), and from these, beliefs were elicited about their heart failure treatment, resulting in the generation of a repertory grid. Adherence was measured using the Medication Adherence Report Scale (MARS). Patients with a MARS score ≥ 23 were categorized as "adherent" and those with a score ≤ 22 as "nonadherent." The generated grids were analyzed descriptively and constructs from all grids themed and the frequency of these constructs compared between adherent and nonadherent patients. RESULTS: Individual grids provided insight into the different beliefs that patients held about their heart failure treatment. The themed constructs "related to water," "affect the heart," "related to weight," and "benefit to the heart" occurred more frequently in adherent patients compared with nonadherent patients. CONCLUSION: The repertory grid technique elicited beliefs of individual participants about the treatment of their heart failure. Constructs from self-reported adherent patients were more likely to reflect that their medicines and self-care activities were related to water and weight, and affect and benefit to the heart. Providing clinicians with better insight into individuals' beliefs about their treatment may facilitate the development of tailored interventions to improve adherence.

Improving hospital outcomes in patients admitted from residential aged care: results from a controlled trial.

BACKGROUND: residents of aged care are old, frail and frequently require hospital management of intercurrent illness, but hospital outcomes are poor. OBJECTIVE: to identify the impact of an interdisciplinary care model on medical inpatients admitted from residential aged care (RAC). DESIGN: pre-planned subgroup analysis of controlled trial. SETTING: general medical units of a teaching hospital in Brisbane, Australia. SUBJECTS: consecutive patients aged over 65 admitted from RAC (n = 189) or the community (n = 815). METHODS: all admitted general medical patients were allocated by existing cyclical roster to control (usual care) or intervention units (interdisciplinary care consisting of improved allied health staffing, consistent teams, daily team meetings and early discharge planning). Patient characteristics and outcomes of care were compared between RAC and community subgroups. In the RAC subgroup, outcomes were compared between the control and intervention groups. RESULTS: patients admitted from RAC had much higher in-hospital mortality (13 versus 6%) and 6-month mortality (35 versus 17%) than those from community. RAC residents receiving the intervention had a significant reduction in in-hospital mortality (4 versus 22% P < 0.001) sustained at 6 months (28 versus 44% P = 0.02). CONCLUSIONS: poor hospital outcomes for RAC residents may reflect prevailing models of inpatient care.

Exercise training in recently hospitalized heart failure patients enrolled in a disease management programme: design of the EJECTION-HF randomized controlled trial.

AIMS: The Exercise Joins Education: Combined Therapy to Improve Outcomes in Newly-discharged Heart Failure (EJECTION-HF) study will evaluate the impact of a supervised exercise training programme (ETP) on clinical outcomes in recently hospitalized heart failure patients attending a disease management programme (DMP). Methods This multisite, pragmatic randomized controlled trial enrols patients discharged from participating hospitals with clinical evidence of heart failure who are willing and able to participate in a DMP and considered clinically safe to exercise. Enrolment includes participants with impaired and preserved left ventricular systolic function. Baseline assessment and programme commencement occur within 6 weeks of hospital discharge. The control group DMP includes individualized education and follow-up from a multidisciplinary heart failure team; a weekly education programme for 12 weeks; self-management advice; and medical follow-up. Home exercise is recommended for all participants. In addition, intervention participants are offered 36 supervised, structured gym-based 1 h exercise sessions over 24 weeks. Sessions are tailored to exercise capacity and include aerobic, resistance, and balance exercises. Enrolment target is 350 participants. Primary outcome is 12-month mortality and readmissions. Secondary outcomes include blinded evaluation of depressive symptoms, sleep quality, cognition, and functional status (activities of daily living, 6 min walk distance, grip strength) at 3 and 6 months. A cost-utility analysis will be conducted. CONCLUSION: This study will enrol a representative group of hospitalized heart failure patients and measure a range of patient and health service outcomes to inform the design of post-hospital DMPs for heart failure. Enrolment will be completed in 2013. ACTRN12608000263392.

Timing and risk factors for functional changes associated with medical hospitalization in older patients.

BACKGROUND: Older medical patients often experience a decline in function associated with hospitalization. Some of this decline is already established at hospital admission, whereas some occurs during hospitalization. Objectives of this study were to separately describe pre-hospital and in-hospital functional changes in older Australian medical patients and to identify risk factors associated with these functional changes. METHODS: Secondary analysis of data from a prospective controlled trial conducted in general medical units of an Australian tertiary teaching hospital. Participants were 615 consecutive patients aged 65 years or older admitted under a general medical unit for more than 2 days, discharged alive, and not fully dependent at pre-admission baseline. Activities of daily living measured 2 weeks before admission, at admission, and at discharge were used to calculate rates of pre-hospital and in-hospital decline and of in-hospital recovery to pre-admission function. Potential predictors including age, sex, diagnosis, illness severity, pre-admission function, pre-admission supports, and documented "geriatric syndromes" (dementia, falls, malnutrition) were investigated for each functional change outcome using multiple logistic regression models. RESULTS: Sixty-four percent of participants had pre-hospital functional decline; only 42% of these had recovered to pre-admission function by hospital discharge. Only 7% had in-hospital decline. The different functional change variables had distinct patterns of predictors. CONCLUSIONS: Most decline occurred prior to hospitalization and was associated with common indicators of poor outcomes in hospitalized elders. In-hospital decline was uncommon, suggesting that in-hospital recovery may be a more appropriate intervention target.

Optimising care of acute coronary syndromes in three Australian hospitals.

OBJECTIVE: To improve quality of in-hospital care of patients with acute coronary syndromes using a multifaceted quality improvement program. DESIGN: Prospective, before and after study of the effects of quality improvement interventions between October 2000 and August 2002. Quality of care of patients admitted between 1 October 2000 and 16 April 2001 (baseline) was compared with that of those admitted between 15 February 2002 and 31 August 2002 (post-intervention). SETTING: Three teaching hospitals in Brisbane, Australia. STUDY PARTICIPANTS: Consecutive patients (n = 1594) admitted to hospital with acute coronary syndrome [mean age 68 years (SD 14 years); 65% males]. INTERVENTIONS: Clinical guidelines, reminder tools, and educational interventions; 6-monthly performance feedback; pharmacist-mediated patient education program; and facilitation of multidisciplinary review of work practices. MAIN OUTCOME MEASURES: Changes in key quality indicators relating to timing of electrocardiogram (ECG) and thrombolysis in emergency departments, serum lipid measurement, prescription of adjunctive drugs, and secondary prevention. RESULTS: Comparing post-intervention with baseline patients, increases occurred in the proportions of eligible patients: (i) undergoing timely ECG (70% versus 61%; P = 0.04); (ii) prescribed angiotensin-converting enzyme inhibitors (70% versus 60%; P = 0.002) and lipid-lowering agents (77% versus 68%; P = 0.005); (iii) receiving cardiac counselling in hospital (57% versus 48%; P = 0.009); and (iv) referred to cardiac rehabilitation (17% versus 8%; P < 0.001). CONCLUSIONS: Multifaceted approaches can improve care processes for patients hospitalized with acute coronary syndromes. Care processes under direct clinician control changed more quickly than those reliant on complex system factors. Identifying and overcoming organizational impediments to quality improvement deserves greater attention.

Achieving better in-hospital and after-hospital care of patients with acute cardiac disease.

In patients hospitalised with acute coronary syndromes (ACS) and congestive heart failure (CHF), evidence suggests opportunities for improving in-hospital and after-hospital care, patient self-care, and hospital-community integration. A multidisciplinary quality improvement program was designed and instigated in Brisbane in October 2000 involving 250 clinicians at three teaching hospitals, 1080 general practitioners (GPs) from five Divisions of General Practice, 1594 patients with ACS and 904 patients with CHF. Quality improvement interventions were implemented over 17 months after a 6-month baseline period and included: clinical decision support (clinical practice guidelines, reminders, checklists, clinical pathways); educational interventions (seminars, academic detailing); regular performance feedback; patient self-management strategies; and hospital-community integration (discharge referral summaries; community pharmacist liaison; patient prompts to attend GPs). Using a before-after study design to assess program impact, significantly more program patients compared with historical controls received: ACS: Angiotensin-converting enzyme (ACE) inhibitors and lipid-lowering agents at discharge, aspirin and beta-blockers at 3 months after discharge, inpatient cardiac counselling, and referral to outpatient cardiac rehabilitation. CHF: Assessment for reversible precipitants, use of prophylaxis for deep-venous thrombosis, beta-blockers at discharge, ACE inhibitors at 6 months after discharge, imaging of left ventricular function, and optimal management of blood pressure levels. Risk-adjusted mortality rates at 6 and 12 months decreased, respectively, from 9.8% to 7.4% (P = 0.06) and from 13.4% to 10.1% (P = 0.06) for patients with ACS and from 22.8% to 15.2% (P < 0.001) and from 32.8% to 22.4% (P = 0.005) for patients with CHF. Quality improvement programs that feature multifaceted interventions across the continuum of care can change clinical culture, optimise care and improve clinical outcomes.
