A web-based tailored nursing intervention (TAVIE en m@rche) aimed at increasing walking after an acute coronary syndrome: Multicentre randomized trial.

From 40%-60% of acute coronary syndrome patients self-report insufficient levels of physical activity. No effect was found on the primary outcome of daily steps. Although not significant, a greater increase in MVPA was found at 12 weeks. The primary outcome can be explained by most of the sample having attained the physical activity recommendation at randomization. Caution in interpreting the non-significant increase in MVPA is warranted due to attrition bias and statistical uncertainty. Future directions may consider the timing of randomization in relation to meeting the needs of insufficiently active acute coronary syndrome patients.
