Impact of a brief psychological intervention on lifestyle, risk factors and disease knowledge during phase I of cardiac rehabilitation after acute coronary syndrome.

INTRODUCTION: This study examined the efficacy of a brief inpatient psychoeducational intervention on knowledge about acute coronary syndromes (ACS), control of risk factors, and adaptive health habits and lifestyle. The intervention was intended to facilitate rehabilitation after ACS and its short- and medium-term impact was assessed.

METHODS: One hundred and twenty-one patients with ACS, admitted to a central cardiology unit in Portugal, were randomized to an experimental group (EG, n=65) or a control group (CG, n=56). We used the Portuguese versions of the Knowledge Questionnaire and the Health Habits Questionnaire. Patients were assessed at hospital admission, hospital discharge and one- and two-month follow-up.

RESULTS: The intervention had a significant impact, increasing knowledge about ACS (F=500.834; p=0.000) in the EG, which was maintained at two-month follow-up, and changing health habits at two-month follow-up (F=218.129; p=0.000). The CG demonstrated decreased knowledge (F=3.368; p=0.069) during the same period.

CONCLUSIONS: A brief inpatient psychoeducational intervention has a positive effect on knowledge about ACS, risk factor control and promotion of positive health habits, and is effective in improving cardiac rehabilitation.
