Impact of Heart Failure Center Program on Cardiac Outcomes in Patients With Heart Failure

Completed

Conditions: Death
Congestive Heart Failure

Registration Number: NCT01416285

Lead Sponsor: Chang Gung Memorial Hospital

Brief Summary: Congestive heart failure (CHF) is a major public health problem worldwide. CHF carries a devastating prognosis, which resembles that of some types of malignant cancer. Despite substantial improvements in the management of the disease, the prognosis remains poor especially in advanced stages of the disease. For these patients, self-management plan includes monitoring of symptoms such as fatigue and shortness of breath, daily weighing, and knowing what to do if signs of deterioration appear, and when to report the changes to health. The investigators hypothesize that patients in the heart failure management programs that promote self-management by means of intensive education, edema index-assistance, and telephone follow-up can improve their functional status and quality of life, as well as the biomarkers of CHF, left ventricular systolic function, proteinuria and nutritional status.

Detailed Description: Congestive heart failure (CHF) is a major public health problem world-wide. CHF carries a devastating prognosis which resembles that of some types of malignant cancer. Its incidence rises steadily from 0.02 per 1000 population per year in those aged 25 to 34 years to 11.6 in those aged 85 years or older. Despite substantial improvements in the management of the disease, the prognosis remains poor especially in advanced stages of the disease. About half of the patients diagnosed with CHF die within 4 years of diagnosis. With the increasing number of patients with CHF being referred from hospital to primary health care, the demands for expanded services in primary health care have increased. Caring for patients with CHF often involves a number of physical, medical, behavioral, psychological and social factors, and requires appropriate attention to all aspects of care, both pharmacological and non-pharmacological. Educating patients about CHF treatment and the consequences of CHF has been shown to improve self-management behavior. For patients with CHF, the self-management plan includes monitoring of symptoms such as fatigue and shortness of breath, daily weighing, and knowing what to do if signs of deterioration appear, and when to report the changes to health care provider. In patients with CHF, the prognosis worsens considerably once malnutrition develops. Mortality at 18 months in unselected patients with CHF in whom cardiac cachexia had been diagnosed was as high as 50% compared to in non-cachectic patients from the same study population. In addition, amount of proteinuria has been known to be related to atherosclerosis burden and disease severity regarding lots of disease entities. The atherosclerosis score is also probably modifiable by life style intervention and educational program. CHF can also activate a few neurohormone and natriuretic peptides, among which brain natriuretic peptide is the most world-wide used. Summarized, in this study, to estimate the effect of CHF education and self-management program, the parameters adopted include blood brain natriuretic peptide and albumin levels, atherosclerosis scores, proteinuria, renal function, changes in life quality, left ventricular ejection fraction, and cardiac outcomes. In Taiwan, so far, the investigators don't have this kind of CHF education and self-care system. The investigators hypothesize that patients in the heart failure management programs that promote self-management by means of intensive education, edema index-assistance, and telephone follow-up can improve their functional status and quality of life, as well as the biomarkers of CHF, left ventricular systolic function, proteinuria and nutritional status.

Primary Outcome Measures

Name	Time	Method
All-cause Death, Heart Failure-related Re-hospitalizations, and a Composite Outcome of Both Death and Heart Failure-related Re-hospitalizations	2 year	Follow-up began after randomization. Follow-up data were prospectively obtained every month from hospital records, personal communication with patients' physicians, telephone interviews, and records of regular visits to staff physicians' outpatient clinics. 'Re-hospitalization'was defined as heart failure-related re-hospitalization.'All causes of death' was also considered to be an event. All-cause death was chosen as an endpoint because of the inter-relationship of heart failure with many other comorbidities in the patient cohort. A committee of three cardiologists adjudicated all hospitalizations without knowledge of the patients' clinical data to determine whether events were related to worsening heart failure. Based on these two different endpoints, time to the first event was analyzed.
