PURPOSE: To objectively assess, in stable cardiac patients, the adherence to
physical activity (PA) recommendations using an accelerometer at 2 or 12 months
after the discharge of cardiac rehabilitation program (CRP). METHODS: Eighty cardiac patients wore an accelerometer at 2 months (group 1, short-term
adherence, n=41) or one-year (group 2, long-term adherence, n=39) after a CRP
including therapeutic education about regular PA. PA was classified as "light"
(1.8-2.9 Metabolic Equivalent of Task [METs]), "moderate" (3-5.9 METs), or
"intense" (>6METs). Energy expenditure (EE, in Kcal) and time (min) spent in
these three different levels were measured during a one-week period with the
MyWellness Key actimeter (MWK). Motivational readiness for change was also
assessed at the end of CRP. Patients were considered as physically active when a
minimum of 150min of moderate PA during the one-week period was achieved.
RESULTS: Both groups were comparable, except for exercise capacity at the end of
the CRP which was slightly higher in group 1 (167.5+/-42.3 versus 140.7+/-46.1W,
P<0.01). The total weekly active EE averaged 676.7+/-353.2kcal and
609.5+/-433.5kcal in group 1 and 2, respectively. The time spent within the
light-intensity range PA was 319.4+/-170.9 and 310.9+/-160.6min, and the time
spent within the moderate-intensity range averaged 157.4+/-115.4 and
165+/-77.2min per week for group 1 and 2, respectively.
Fifty-three percent and
41% of patients remained active in both groups respectively. CONCLUSION: About
half of the patients are non-adherent to PA after CRP and do not reach target
levels recommended by physicians. The first 2 months following the discharge of
CRP seem to be of outmost importance for lifestyle modifications maintenance, and
further study monitoring more closely PA decrease could help to clarify the
optimal follow-up options.
