Switching from high-efficacy lipid-lowering therapies to simvastatin and low-density lipoprotein cholesterol goal attainment in coronary heart disease/coronary heart disease-equivalent patients

Background As mortality due to cardiovascular disease increases throughout the world, accurate data on risk factors such as hyperlipidemia are required. This is lacking in the Asia-Pacific region. Design The observational Dyslipidemia International Study (DYSIS) II was established to quantify the extent of hyperlipidemia in adults with acute and stable coronary heart disease globally. Methods Patients with stable coronary heart disease or hospitalised with an acute coronary syndrome were enrolled across nine Asia-Pacific countries from July 2013 to October 2014. Lipid-lowering therapy and low-density lipoprotein cholesterol target attainment (<70 mg/dL) were assessed. The acute coronary syndrome cohort was followed up 4 months post-discharge. Results Of the 4592 patients enrolled, 2794 had stable coronary heart disease and 1798 were admitted with an acute coronary syndrome. In the coronary heart disease cohort, the mean low-density lipoprotein cholesterol level was 86.9 mg/dL, with 91.7% using lipid-lowering therapy and 31% achieving low-density lipoprotein cholesterol of less than 70 mg/dL. In the acute coronary syndrome cohort at admission, the corresponding values were 103.2 mg/dL, 63.4% and 23.0%, respectively. Target attainment was significantly higher in lipid-lowering therapy-treated than non-treated patients in each cohort (32.6% vs. 12.9% and 31.1% vs. 9.0%, respectively). Mean atorvastatin-equivalent dosages were low (20 ± 15 and 22 ± 18 mg/day, respectively), with little use of non-statin adjuvants (13.0% and 6.8%, respectively). Low-density lipoprotein cholesterol target attainment had improved by follow-up for the acute coronary syndrome patients, but remained low (41.7%). Conclusions Many patients in Asia at very high risk of recurrent cardiovascular events had a low-density lipoprotein cholesterol level above the recommended target. Although lipid-lowering therapy was common, it was not used to its full potential.

Background Determinants of the real-world effectiveness of lipid-lowering therapy have been rarely assessed in an unselected observational coronary heart disease (CHD) community cohort over time. Design Randomly drawn patients (n = 605) from randomly drawn practices (n = 62) were retrospectively followed for a median of 3.6 years (1998-2002) on lipid-lowering therapy (98% statins). Methods Coronary heart disease population-averaged estimates and variances accounting for repeated measurements within patients were obtained using generalized estimating equations. Results Post-treatment low-density lipoprotein-cholesterol (LDL-C) was 124 mg/dl in men and 141 mg/dl in women and was independently associated (all P<0.05) with pre-treatment LDL-C (+ 3.7 mg/dl per 10 mg/dl increment), female sex (+ 14.0 mg/dl), coronary bypass (-9.5 mg/dl), drug-treated diabetes mellitus (-6.8 mg/dl), and era 2002/2001 versus 1999/2000 (- 6.4 mg/dl) in age-adjusted multivariate analyses. Holding pre-treatment LDL-C constant post-treatment LDL-C was associated with pre-treatment Framingham CHD risk in men (- 13.9 mg/dl per doubling of risk), whereas LDL-C control in women resembled that in low-risk men. The likelihood of attaining LDL-C < 100 mg/dl was 0.28 in men and 0.17 in women and was likewise associated with the above factors. Conclusion Low-density lipoprotein-cholesterol control remained low despite lipid-lowering therapy across a wide range of pre-treatment LDL-C and pre-treatment CHD risk. Low-density lipoprotein-cholesterol control in women was inferior to that in men, a finding that warrants attention and clarification.
