Aims To determine the effect of an integrated heart failure management programme, involving patient and family, primary and secondary care, on quality of life and death or hospital readmissions in patients with chronic heart failure. Methods and ResultsThis trial was a cluster randomized, controlled trial of integrated primary/secondary care compared with usual care for patients with heart failure. The intervention involved clinical review at a hospital-based heart failure clinic early after discharge, individual and group education sessions, a personal diary to record medication and body weight, information booklets and regular clinical follow-up alternating between the general practitioner and heart failure clinic. Follow-up was for 12 months. One hundred and ninety-seven patients admitted to Auckland Hospital with an episode of heart failure were enrolled in the study. There was no significant difference between the intervention and control groups for the combined end-point of death or hospital readmission. The physical dimension of quality of life showed a greater improvement in the intervention group from baseline to 12 months compared with the control group ( 11·1 vs 5·8 respectively, 2P=0·015). The main effect of the intervention was attributable to the prevention of multiple admissions (56 intervention group vs 95 control group, 2P=0·015) and associated reduction in bed days.Conclusions This integrated management programme for patients with chronic heart failure improved quality of life and reduced total hospital admissions and total bed days.

Background: Multidisciplinary heart failure programs including patient education and self-management strategies such as daily recording of body weight and use of a patient diary decrease hospital readmissions and improve quality of life. However, the degree of uptake of individual components of these programs and their contribution to patient benefit are uncertain. Methods: Patients with heart failure admitted to Auckland Hospital were randomised into the management or usual care groups of the Auckland heart failure management study (AHFMS). Patients in the management group were given a heart failure diary for the recording of daily weights, attended a heart failure clinic and were encouraged to attend three education sessions. Patients in the usual care group received routine clinical care, mainly from general practitioners. Patients were followed to 12 months. This study investigated the uptake of self-management by assessing diary use and self-weighing behaviour in the group receiving the heart failure intervention, and compared the level of knowledge of heart failure self-management of the management group to the control group after 12 months. Results: Of the 197 patients in the AHFMS, 100 patients were included in the management group and received a diary and education about heart failure self-management including monitoring weight daily. Of these patients, 76 patients used the diary. These patients were on more medication; were more likely to attend the education sessions, heart failure clinic, and primary care, and had a lower mortality rate over the course of the study. Variables independently associated with use of the diary included less severe symptoms (OR 15, 95% confidence intervals 1.7, 144), frequent attendance at the heart failure clinic (OR 15, 95% CI 3, 78) and attendance at an education session (OR 8, 95% CI 1.5, 42). Of the 76 patients who used the diary, 51 weighed themselves regularly. More of these patients owned scales at home; they were also more likely to attend the education sessions, and experienced fewer hospital admissions than those patients who did not weigh themselves regularly. Variables independently associated with regular self-weighing included the presence of scales at home (OR 6.3, 95% CI 1.7, 14.1), left ventricular ejection fraction )30% (OR 4.3, 95% CI 1.1, 17.5), and attendance at the education session(s) (OR 6.3, 95% CI 1.7, 14.1). Patients in the management group exhibited higher levels of knowledge at 12 months of follow-up and were more likely to monitor their condition using daily weighing, compared to the control group. Conclusions: At 12 months of followup, implementation of self-management strategies including daily weight monitoring and level of education on self-management was significantly higher in the management group than the control group. For the patients in the management group, not using the diary or inability to perform daily weighing were associated with less frequent attendance at the heart failure clinic and education sessions and poorer he...

BackgroundLeft ventricular hypertrophy (LVH) is a strong predictor of cardiovascular disease and is common among patients with type 2 diabetes. However, no systematic screening for LVH is currently recommended for patients with type 2 diabetes. The purpose of this study was to determine whether NT-proBNP was superior to 12-lead electrocardiography (ECG) for detection of LVH in patients with type 2 diabetes.MethodsProspective cross-sectional study comparing diagnostic accuracy of ECG and NT-proBNP for the detection of LVH among patients with type 2 diabetes. Inclusion criteria included having been diagnosed for > 5 years and/or on treatment for type 2 diabetes; patients with Stage 3/4 chronic kidney disease and known cardiovascular disease were excluded. ECG LVH was defined as either the Sokolow-Lyon or Cornell voltage criteria. NT-proBNP level was measured using the Roche Diagnostics Elecsys assay. Left ventricular mass was assessed from echocardiography. Receiver operating characteristic curve analysis was carried out and area under the curve (AUC) was calculated.Results294 patients with type 2 diabetes were recruited, mean age 58 (SD 11) years, BP 134/81 ± 18/11 mmHg, HbA1c 7.3 ± 1.5%. LVH was present in 164 patients (56%). In a logistic regression model age, gender, BMI and a history of hypertension were important determinants of LVH (p < 0.05). Only 5 patients with LVH were detected by either ECG voltage criteria. The AUC for NT-proBNP in detecting LVH was 0.68.ConclusionsLVH was highly prevalent in asymptomatic patients with type 2 diabetes. ECG was an inadequate test to identify LVH and while NT-proBNP was superior to ECG it remained unsuitable for detecting LVH. Thus, there remains a need for a screening tool to detect LVH in primary care patients with type 2 diabetes to enhance risk stratification and management.

This study demonstrates that N-BNP measurement significantly improves the diagnostic accuracy of HF by GPs over and above customary clinical review.

Both E/Ea and NT-proBNP predicted hospitalization and when used in a two-step approach (NT-proBNP first, followed by E/Ea), the combination of both (elevated NT-proBNP and elevated E/Ea) identified those patients at highest risk, thus supporting a complementary approach for echocardiography and NT-proBNP in patients with HF symptoms.
