Abstract
Background: Primary care is well positioned to facilitate cardiovascular risk improvement and reduce future cardiovascular disease (CVD) burden.
Methods: The efficacy of risk factor screening, behavioural counselling, and pharmacological treatment to lower CVD risk was assessed via a prospective pre- and postintervention health risk assessment, individualized intervention with behaviour modification, risk factor treatment, and linkage to community programs, with 1-year follow-up and final health risk assessment. Primary outcome was the proportion of subjects with moderate and high baseline Framingham Risk Score (FRS) reducing their risk by 10% and 25%, respectively; the secondary end point was the proportion dropping ≥ 1 risk category.
Results: Patients were enrolled (N = 1509) from March 2006 through October 2008 and 72% completed the study. This analysis focuses on 563 subjects with moderate or high baseline FRS, and excluded 325 low-risk patients and 205 with established CVD or diabetes mellitus. Median age was 56 years, 57.7% were female. The primary outcome was achieved in 31.8% (N = 112; 95% confidence interval [CI], 26.9%-36.6%) of moderate risk FRS participants and 47.9% (N = 101; 95% CI, 41.2%-54.6%) of high-risk participants. The secondary outcome was achieved by 37.2% (N = 210; 95% CI, 33.2%-41.2%). Prevalence of metabolic syndrome fell from 79.2% (N = 446; 95% CI, 75.9%-82.6%) at entry to 52.8% (N = 303; 95% CI, 48.7%-56.9%) at study end. Significant improvements in all modifiable risk factors occurred through lifestyle modification.
Conclusions: Global cardiovascular risk can be effectively decreased via lifestyle changes informed by readiness to change assessment and individualized counselling targeting specific behaviours.
