Abstract
- <bold>Introduction: </bold>Primary cardiovascular prevention through simultaneously targeting multiple risk factors may be even more effective than single risk factor modification in older adults. The effects of multicomponent cardiovascular prevention on cardiovascular risk are explored.<bold>Study Design: </bold>Post hoc analysis of the cluster randomized Prevention of Dementia by Intensive Vascular care trial.<bold>Setting/participants: </bold>Community-dwelling older adults aged 70-78 years, free from cardiovascular disease at baseline (n=2,254, 63.9% of the Prevention of Dementia by Intensive Vascular care trial population).<bold>Intervention: </bold>Between 2006 and 2015, the intervention group received nurse-led vascular care every 4 months at the general practitioner practice, the control group received care as usual.<bold>Main Outcome Measures: </bold>Cardiovascular disease events and Systematic COronary Risk Evaluation in Older People (SCORE-OP), an index based on six risk factors for cardiovascular mortality. Effects were adjusted for clustering and assessed using mixed effects Cox proportional-hazard models and linear mixed models respectively.<bold>Results: </bold>There was no effect of the intervention on cardiovascular disease events (hazard ratio=0.99, 95% CI=0.71, 1.38). During a median follow-up of 6.1 years, SCORE-OP increased from 14.0% and 13.9% to 23.9% and 25.0% in the intervention and control group, respectively (adjusted mean difference in increment in SCORE-OP between the study groups 0.60%, 95% CI= -0.01, 1.20). Exploratory analyses showed a larger reduction of 2.4 mmHg (95% CI=0.9, 3.9) in systolic blood pressure and 1.9% (95% CI=0.4, 3.4) in current cigarette smoking in the intervention group compared with the control group.<bold>Conclusions: </bold>Multicomponent cardiovascular prevention did not improve the overall risk profile in older adults in a primary prevention setting, relative to usual care. However, exploratory analyses showed an effect on blood pressure and smoking cessation. Possibly, contrast between study groups was too small because of the Hawthorne (being part of a study) effect and increasing quality of (preventive) health care for older adults, to yield an effect on the risk profile.
