Abstract The aim of this study was to evaluate the effects of a supervised cardiac rehabilitation (CR) program on long-
term quality of life (QoL) of patients with heart failure (HF).Methods: A sample of 21 HF patients, previously sedentary,
NYHA II, was randomly divided into two groups: the CR group (N = 13) and the control group (CG = 8). The CR
consisted of sessions of 120 minutes/day, 3 times/week,for 60 days. CR group performed their activities under supervision
at a rehabilitation clinic, and CG received standard care and was instructed to exercise at home. All patients underwent a
maximal symptom-limited test at the beginning and after 30 and 60 days of CR. QoL was monitored after 60-days, 6, 12
and 18 months of CR. Results:Two-way ANOVA for repeated measures, followed by Tukey’s test for statistical analysis
showed significantimprovement in peak VO
2
at 30 and 60-days of CR (p<0.05). QoL improved after 60-days of CR and
remained improved throughout the 18following months in the supervised CR group. The use of hospital emergency
services became less frequent (p=0.023) and there was a trend for better survival after 18 months of follow-up
(p=0.092).Conclusion: CR was effective upon cardiopulmonary and QoL aspects.

1. Introduction
Heart Failure (HF) is, in most of the cases, a status due to
the evolution of a number of illnesses, such as arterial
hypertension or high blood pressure, coronary heart disease
(CHD), acute myocardial infarction (AMI), valvediseases
and cardiac arrhythmic illnesses[1,2]. The main HF
symptoms are dyspnea, physical activity intolerance and
quality of life reduction[2,3]. HF represents the main cause
for hospital admission in individuals aging 65 and beyond.
It is a fact that HF prevalence is increasing, and among the
factors that might be contributing to this situation we
highlightthe increase in life expectancy of the general
population and greater effectiveness of new drugs[4].
However, despite the advent of new drugs, mortality and
morbidity indexes are still high in this type of affection[1,2].
Cardiac rehabilitation (CR) has become mandatory in HF
patients. Objectives of CR include mortality and
morbidityreduction, quality of life improvement and cos
reduction[5-13].

Several studies have already demonstrated the efficacy of
exercise - based CR programs[7-11], but a meta - analysis
of randomized controlled trials[12] has concluded that
quality of life improves to similar levels in patients
receiving CR and standard care.The aim of the present
study was to evaluate the effectiveness of asupervised CR
program in the quality of life of HF subjects, as compared
to standard care. Success indicators were based on
cardiorespiratory capacity analysis, functional capacity,
quality of life, survival and/or mortality.
2. Methods
The present study was based on a longitudinal
prospective design composed by two phases: 1
st
-supervised
CR or non-supervised CR (control) for 60 days; and 2
nd
- 18
months follow-up after CR. All procedures in the study
were in conformation with resolution 196/96 of the
Brazilian Health Council(http://conselho.saude.gov.br/resol
ucoes/1996/Reso196.doc) and the declaration of
Helsinki[14], and were approved by the local University
ethics committee (protocol number: 004/2005).
