Impact of Implementing the 2013 ACC/AHA Cholesterol Guidelines on Vascular Events in a Statewide Community-Based Practice Registry.

ABSTRACT: Electronic health record data were analyzed to estimate the number of statin-eligible adults with the 2013 American College of Cardiology/American Heart Association cholesterol guidelines not taking statin therapy and the impact of recommended statin therapy on 10-year atherosclerotic cardiovascular disease (ASCVD10 ) events. Adults aged 21 to 80 years in an outpatient network with ≥1 clinic visit(s) from January 2011 to June 2014 with data to calculate ASCVD10 were eligible. Moderate-intensity statin therapy was assumed to lower low-density lipoprotein cholesterol by 30% and high-intensity therapy was assumed to reduce low-density lipoprotein cholesterol by 50%. ASCVD events were assumed to decline 22% for each 39 mg/dL decline in low-density lipoprotein cholesterol. Among 411,768 adults, 260,434 (63.2%) were not taking statins and 103,478 (39.7%) were eligible for a statin, including 79,069 (76.4%) patients with hypertension. Estimated ASCVD10 events were 18,781 without and 13,328 with statin therapy, a 29.0% relative and 5.3% absolute risk reduction with a number needed to treat of 19. The 2013 cholesterol guidelines are a relatively efficient approach to reducing ASCVD in untreated, statin-eligible adults who often have concomitant hypertension.

Project description:ObjectiveWe examined the use of cholesterol-lowering drugs in Taiwan in high-risk patients before and after the release of the 2013 American College of Cardiology and the American Heart Association (ACC/AHA) cholesterol guidelines.DesignRetrospective observational study.SettingKaohsiung Chang Gung Memorial Hospital database, Kaohsiung City, Taiwan.ParticipantsOutpatients aged ≥20 years with atherosclerosis cardiovascular disease, familial hypercholesterolaemia and diabetes.Primary and secondary outcome measuresData on brand and generic names, use and dosage of cholesterol-lowering drugs in 2012 and 2015 were compiled and the total amount used was calculated. Differences in usage and market share were compared. Usage rates of single and fixed-dose combination (FDC) products were compared.ResultsThe number of patients receiving ambulatory care increased from 36 367 in 2012 to 41 807 in 2015. Single (3 679 979-4 568 086 tablets) and FDC (540 522-572 954 tablets) product use increased from 2012 to 2015, respectively. Statins were the most commonly prescribed medications in 2012 (71.14%) and 2015 (72.91%). The average monthly consumption of statin among high-risk patients in 2012 was 269 948.8 tablets, and it increased significantly to 343 975.3 tablets in 2015. The average monthly consumption of pitavastatin was 34 113.4 tablets in 2015, which was significantly higher than 0 in 2012. Conversely, the highest decline was observed for fluvastatin use, with the average monthly consumption being 38 754.3 tablets in 2015, which was significantly lower than 45 929.8 tablets consumed in 2012. Regarding FDC therapy for cholesterol-lowering drugs, Vytorin (ezetimibe 10 mg + simvastatin 20 mg) use was the highest among all FDCs in 2015.ConclusionsThe 2013 ACC/AHA cholesterol guidelines likely promoted the use of fixed-dose, high-intensity and moderate-intensity monotherapy and FDC therapy statins in high-risk groups, and this was consistent with the use of high-intensity or moderate-intensity statins in the present study. Furthermore, these changes were associated with increased effectiveness and reduced adverse effects.

Project description:Background: The recent American College of Cardiology/American Heart Association (ACC/AHA) guidelines redefined blood pressure levels 130-139/80-89 mmHg as stage 1 hypertension. However, the association of stage 1 hypertension with cardiovascular disease (CVD) and its age-specific differences among the rural women in Liaoning province remains unclear. It needs to be quantified in considering guideline adoption in China. Methods: In total, 19,374 women aged ≥35 years with complete data and no cardiovascular disease at baseline were followed in a rural community-based prospective cohort study of Liaoning province, China. Follow-up for the new cases of CVD was conducted from the end of the baseline survey to the end of the third follow-up survey (January 1, 2008-December 31, 2017). Adjusted Cox proportional hazards models were applied to estimate the Hazard Ratios (HR) and 95% Confidence Intervals (CI) with the normal blood pressure as a reference. Results: During the median follow-up period of 12.5 years, 1,419 subjects suffered all-cause death, 748 developed CVD, 1,224 participants suffered stroke and 241 had Myocardial Infarction (MI). Compared with normal BP, Stage 1 hypertension had a HR (95% CI) of 1.694 (1.202-2.387) in CVD mortality, 1.575 (1.244-1.994) in the incidence of stroke. The results obtained that the risk of CVD mortality and incidence of stroke was significantly associated with stage 1 hypertension in rural women aged ≥45 years after adjusting for other potential factors. However, in participants aged 35-44 years, stage 1 hypertension was not associated with an increased risk of cardiovascular disease. Conclusions: The newly defined stage 1 hypertension is associated with an increased risk of CVD mortality and also incidence of stroke in the rural women aged ≥45 years population of Liaoning province. This study can be a good reference for health policy makers and clinicians workers to make evidence-based decisions toward lowering burden of cardiovascular disease more efficient, timely measures on prevention and control of stage 1 hypertension in China.
