Clinical Trial Summary
RATIONALE AND OBJECTIVE OF THE STUDY
Patients with low functional capacity (frail patients) with cardiovascular disease, in
particular those undergoing invasive procedures or suffering from coronary artery disease,
have a much higher adverse events, death and re-hospitalizations. and complications,
suggesting the need for a more accurate functional stratification and a more careful
evaluation of the risk/benefit ratio of some invasive procedures. An early and ad hoc
physical activity intervention could be improve functional autonomy of these patients early
after discharge with benefit on long-term outcome. The present study is performed to assess
the impact, evaluated by Short Physical Performance Battery (SPPB), of a program of physical
activity early after discharge in elderly patients aged 75 years and older with low physical
performance.
This is an interventional, multicenter, prospective, randomized, phase III study. The present
study is expected to enroll elderly patients admitted to hospital for acute coronary syndrome
undergoing percutaneous coronary angioplasty and stratified with SPPB score predischarge. At
the moment of discharge there will be a screening: patients with SPPB score 0-2 o 10-12 will
be exclusively followed up by clinical visit every year. Patients with SPPB score 3-9 will be
evaluated during the inclusion visit when SPPB will be repeated. If SPPB score will be 0-3 or
10-12, patients will be considered screening failure and will be followed up by clinical
visit; patients with SPPB score between 4 to 9 will be randomized to standard of care (see
below) or to an ad hoc physical activity program (see below). The aim of the study is to
demonstrate 6 months later an improvement in the SPPB score (at least 1 point) in patients
randomized to physical activity intervention versus patients randomized to standard of care.
All patients will be evaluated until 3 years after randomization.
Description:
BACKGROUND Physical activity helps to prevent stroke, type II diabetes mellitus and coronary
artery disease, while physical inactivity has been linked to declines in both muscle strength
and cardiovascular function. Despite the evidence of the benefits of physical activity are
well known, 61% of adults over the age of 65 are not meeting the recommended levels of
physical activity. It has been demonstrated that regular physical exercise benefits in
primary and secondary prevention in patients with cardiovascular diseases and improves
functional capacity. The incidence of cardiovascular disease is higher in older patients
(especially over 75 years old). In Italy, life expectancy at birth has reached 80 years in
men and 85 in women; in about 50 years, life expectancy at the age of 80 has increased by an
extraordinary 61% and 55%, respectively, due to more effective therapies and lower mortality
of many diseases. So, as recommended by guidelines, physical activity should be suggested to
older coronary patients; some studies demonstrated the benefit of physical training also in
older patients, but only few studies enrolled patients aged 65 years and over because of some
difficulties about patients' compliance mainly due to logistic problems and lack of
motivation by doctors. As far as we know no studies have evaluated impact of physical
activity intervention on functional capacity of older patients admitted to hospital for acute
coronary syndrome. Among the numerous tests proposed in the literature for the functional
evaluation and objective measures of physical capability in elderly patient, the Short
Physical Performance Battery (SPPB) and the evaluation of hand grip strength (grip strength)
are those characterized by an improved prognostic ability and an easy administration.
RATIONALE AND OBJECTIVE OF THE STUDY Patients with low functional capacity (frail patients)
with cardiovascular disease, in particular those undergoing invasive procedures or suffering
from coronary artery disease, have a much higher adverse events, death and
re-hospitalizations. and complications, suggesting the need for a more accurate functional
stratification and a more careful evaluation of the risk/benefit ratio of some invasive
procedures. An early and ad hoc physical activity intervention could be improve functional
autonomy of these patients early after discharge with benefit on long-term outcome. The
present study is performed to assess the impact, evaluated by Short Physical Performance
Battery (SPPB), of a program of physical activity early after discharge in elderly patients
aged 75 years and older with low physical performance.
STUDY DESIGN This is an interventional, multicenter, prospective, randomized, phase III
study. The present study is expected to enroll elderly patients admitted to hospital for
acute coronary syndrome undergoing percutaneous coronary angioplasty and stratified with SPPB
score predischarge. At the moment of discharge there will be a screening: patients with SPPB
score 0-2 o 10-12 will be exclusively followed up by clinical visit every year. Patients with
SPPB score 3-9 will be evaluated during the inclusion visit when SPPB will be repeated. If
SPPB score will be 0-3 or 10-12, patients will be considered screening failure and will be
followed up by clinical visit; patients with SPPB score between 4 to 9 will be randomized to
standard of care (see below) or to an ad hoc physical activity program (see below). The aim
of the study is to demonstrate 6 months later an improvement in the SPPB score (at least 1
point) in patients randomized to physical activity intervention versus patients randomized to
standard of care. All patients will be evaluated until 3 years after randomization.
RANDOMIZATION
At discharge an investigator doctor and a study coordinator show to patients the study
protocol, aims, risks and benefit. If the patient accepts to participate to the study, he
signs the informed consent and he will be evaluated with SPPB score and other tests in the
screening evaluation (T0). Patients with SPPB score <3 or >9 will be excluded and will be
followed up with exclusively clinical visit every year. Patients with SPPB score 4-9 will be
enrolled and data will be collected in the study case report form. These patients will be
re-evaluated in the inclusion visit 30 days later (T1); if SPPB score will be 0-3 or 10-12
the patients will be considered screening failure and they will be followed up exclusively
with clinical visit every year; on the contrary, if SPPB score will be 4-9, patients will be
randomized to standard of care group or experimental group. There will be a stratified
randomization by:
- male vs. female
- SPPB value 4-6 vs. SPPB value 7-9
- admission for ST-segment elevation myocardial infarction vs. non ST-segment elevation
acute coronary syndrome
DESCRIPTION OF THE STUDY GROUPS
- STANDARD OF CARE GROUP The standard of care group will be recommended about medications
and a correct life style (physical activity, low salt and low fat diet, no smoking) in
order to prevent cardiovascular events. In this 15-minutes talk study doctor will
explain to patients and relatives the importance of aerobic physical activity (30-60
minutes daily, moderate intensity, for example speedy walking, for at least 5
days/weekly) with the aim of reducing cardiovascular risk. Patients will also receive a
brochure with clear explanations. Study doctor and study coordinator will be helpful for
any question and they will ensure that patients and relatives understand the importance
of physical activity for cardiovascular health.
- EXPERIMENTAL GROUP, PHYSICAL ACTIVITY INTERVENTION Besides standard of care, the
experimental group will participate to a program of physical activity intervention.
Following hospital discharge, participants in stable clinical conditions will be
referred by their cardiologist to the exercise-based secondary prevention program in
dedicated centers. All patients should report no difficulty climbing one flight of
stairs without resting or performing basic activities of daily living. The ultimate goal
of the program is long-term promotion and maintenance of a physically active lifestyle
in order to improve cardiorespiratory fitness and functional ability. Patients will be
treated for cardiovascular and other diseases according to accepted international
guidelines. All exercise testing and training sessions will be performed without
discontinuing the prescribed medications. On admission to the program, and quarterly
during follow-up, each patient will perform a 1-km treadmill walk test as previously
described. Briefly, the test will be carried out as follows: the participants will be
instructed to select a pace that they could maintain for 10 to 30 min at a moderate
perceived exercise intensity using the Borg 6-20 scale. Participants will start the test
walking on the level at 2.0 km/h, with subsequent increases of 0.3 km/h every 30 s up to
a walking speed corresponding to a perceived exertion of 11-13 on the Borg scale. The
test will be then started and the rate of perceived exertion acquired every 2 min.
Walking speed will be adjusted to maintain the selected moderate perceived intensity.
Heart rate will be monitored continuously during the test. Blood pressure will be
monitored at least before and immediately after the test. No individual will be excluded
on the basis of his/her performance on the treadmill protocol. Subjects walking at a
perceived moderate speed < 3.0 km/h will perform the test over the distance of 500-m.
The time to complete either 500-m and 1-km will be recorded and averaged walking speed
calculated accordingly.
