The beliefs about the behaviour are as important as the
beliefs about the disease in predicting various behaviours
related to health. This suggests the possibility that the
interventions of change behaviour with groups of patient
would be more effective, targeting beliefs about the
behaviour, instead of the beliefs about the disease. However,
several authors referred that prospective studies about the
impact of perceptions of the disease and adherence to
secondary prevention in patients with CVD are scarce.12
Thus, we intend to evaluate adherence to treatment and
relate the inÁ uence of beliefs about medicines on adherence
to treatment.
