The influence of partners on lifestyle-related risk factors in patients after an acute coronary syndrome
results from the RESPONSE-2 randomized controlled trial
Poster
<p class="MsoNormal" style="line-height:150%"><b>Background </b>Having a partner is associated with better prognosis in patients with cardiovascular disease. However, the influence of partners on modification of patients’ lifestyle-related risk factors (LRFs) is unclear. Therefore, we studied the influence of partners and the level of partner participation on LRF modification in patients after an acute coronary syndrome (ACS) or revascularization. </p> <p class="MsoNormal" style="line-height:150%"><b>Methods </b> The RESPONSE-2 trial was a community-based lifestyle intervention trial comparing nurse-coordinated referral to a comprehensive set of lifestyle interventions (physical activity, weight reduction and/or smoking cessation) to usual care. In the current analysis, we investigated the association of having a partner on the improvement in >1 LRF without deterioration in other LRFs at 12 months follow-up. Secondary, the influence of the level of partner participation (participating partner, non-participating partner and no partner) in the intervention group was studied. </p> <p class="MsoNormal" style="line-height:150%"><b>Results </b>In total 824 individuals (411 intervention, 413 control) were included in the analysis. The presence of a partner was comparable in both groups (intervention 74%, control 69%). In the intervention group, 48% of partners participated in the lifestyle interventions. Overall, having a partner was positively associated with improvement in LRFs (odds ratio (OR) 2.57 (95% confidence interval (CI) 1.57 – 4.21), p<0.001). In the intervention group, having a participating partner was also positively associated with improvement in LRFs compared to patients without a partner (OR 2.45 95% CI 1.25 – 4.79, p=0.009). When analysed the influence of partners on LRFs separately, patients with a participating partner were most successful in reducing weight compared to patients without a partner (OR 2.71 95% CI 1.16 – 6.36, p=0.02).</p> <b>Conclusion </b>Having a partner is associated with improvement on LRFs in patients after ACS or revascularization. Moreover, patients with participating partners in the lifestyle programs were most successful in LRF modification. Involvement of partners in lifestyle interventions should be considered in routine practice.
