Abstract 15632: The Implications of the Recent American College of Cardiology/American Heart Association Guidelines for the Treatment of Blood Cholesterol on a Rural Community: The Heart of New Ulm Project
Introduction: The impact of the new American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines on the volume of statin-eligible patients requires further analysis, particularly in rural communities who are rarely included in traditional large observational cohorts. Methods: We performed a cross-sectional analysis using data from the Heart of New Ulm Project, a population-based program aimed at reducing modifiable cardiovascular disease (CVD) risk factors in rural New Ulm, MN. According to 2010 census data, there were 7,855 adults aged 40-79 years in the target population at that time. The community is served by one health and electronic health records (EHR) system. EHR-based demographics, diagnoses, and medications were analyzed in residents aged 40-79 years in 2012-2013. The prevalence of indications for statin therapy and of use of statins and other lipid-lowering medications were analyzed according to the ACC/AHA guidelines. Results: There were 6,357 residents with a visit during the study period, of which 4,281 had adequate data and were included in the analysis (mean age 59.4 [10.2] years, 52.7% female). In our study sample, 2,529 (59%) met one of the 4 major indications for statin therapy (Table). Of those with an indication, 65% were on a statin, 11% were on a high-intensity statin, and 5% on other lipid-lowering agents. An age stratified analysis demonstrated that 86% of individuals 60-79 years old (n=2,036) are now statin-eligible compared to 35% of individuals 40-59 years old (n=2,245). Conclusion: Using contemporary EHR data from a rural Midwest community, approximately 3 in 5 middle-age residents qualify for statin therapy according to the new guidelines, but only two-thirds of those individuals were taking a statin. Full compliance with the new guidelines will require a significant increase in statin utilization, including more frequent use of high-intensity statins.
