Temporal Trends in the Use of High-Dose Potent Statins following Acute Coronary Syndrome in Israel

Abstract

Objectives: This study aimed to evaluate factors associated with the prescription of high-dose potent statin (HDPS) therapy following hospitalization for acute coronary events. Study Design: Sub-analysis was made using the data of 3,525 patients enrolled in the 2008 and 2010 Acute Coronary Syndrome Israeli Surveys (ACSIS). Methods: Analyses were carried out to identify demographic and clinical factors associated with the prescription of HDPS therapy (atorvastatin 40-80 mg/day or rosuvastatin 20-40 mg/day) at discharge compared with the prescription of lower-dose statins. Results: Among the study patients, 1,387 (39%) were discharged on HDPS, 1,860 (53%) with lower-dose statin regimens and 278 (8%) with no recommendation for statin therapy. Multivariate logistic regression analysis showed that pre-admission usage of HDPS and participation in the more recent (2010) ACSIS survey were independently associated with a higher likelihood of HDPS prescription at discharge from the index event (odds ratio, OR, 21.07, p < 0.001, and 5.61, p < 0.001, respectively), whereas factors independently associated with a lack of HDPS prescription included age >75 years (OR 0.76, p = 0.03), low-density lipoprotein-cholesterol levels <100 mg/dl on admission (OR 0.67, p < 0.001) and a history of heart failure prior to the index hospitalization (OR 0.54, p = 0.0018). The 30-day compliance with the HDPS regimen was 98%. Conclusions: The findings show increased use of HDPS therapy in acute coronary syndrome (ACS) patients, although this mode of medical therapy is still underutilized in the important subset of high-risk ACS patients.
