Methods: Patients from the Cardiac Rehabilitation Unit were included in the study from 2008 to 2018, within a county hospital. The adoption of a healthy diet, exercise and treatment adherence were evaluated by a trained nurse using Nanda/NIC/NOC taxonomies and Likert scale. Compliance was considered when the Likert scale scored 4-5. The influence of these adhesion factors on event-free survival was analyzed. Event was considered as death, acute coronary syndrome, stroke, revascularization or cardiovascular admission.
Results: The mean follow-up was 4.57 years. 241 patients were included: 19% women, mean age 60 years, 54% HTA, 31% diabetics, 62% dyslipidemic, 51.4% smokers.
The influence of healthy diet adoption on event-free survival was analyzed, with a mean of time of 3206 days in the diet compliance group vs 2712, p<0.005. In physical exercise complicance there were no statistically significant differences between the two groups. Treatment adherence improved event-free survival with a mean of time of 3058 days vs 2687, p<0.05.
In the multivariate analysis, only the adoption of a healthy diet showed influence on event-free survival (p<0.05).
Conclusions: Adherence to diet is a basic mainstay of CRP, improving event-free survival, even over treatment adherence or physical activity. This reinforces the fundamental role of self-care in the development of ischemic disease.
