Temporal changes in statin prescription and intensity at discharge and impact on outcomes in patients with newly diagnosed atherosclerotic cardiovascular disease-Real-world experience within a large integrated health care system: The IMPRES study.
Journal of Clinical Lipidology 2018 July
BACKGROUND: Statins are indicated for secondary atherosclerotic cardiovascular disease (ASCVD) prevention; however, multiple surveys have found treatment gaps in clinical application.
OBJECTIVE: To determine trends over 15 years in the prevalence and impact of a statin prescription and dose intensity at discharge after a first ASCVD event.
METHODS: The Intermountain Enterprise Data Warehouse was searched to identify all adults with a first encounter for ASCVD between January 1, 1999 and December 31, 2013, including coronary artery disease, cerebrovascular disease, and peripheral arterial disease, who survived the index event and were followed for ≥3 years or until death. Major adverse cardiovascular events (MACE) were assessed overall and in 5-year increments.
RESULTS: A total of 62,070 patients met inclusion criteria. Mean age was 65.9 ± 13.7 years, and most of them were male (64.7%). Increases in any statin (59.3% to 72.6% to 80.8%) and high-intensity prescription (3.1% to 14.2% to 28.1%) occurred over consecutive 5-year intervals and were greatest in coronary artery disease patients. Statin therapy was associated with a reduced risk of 3-year MACE (multivariable hazard ratio = 0.75 [0.72, 0.78], P < .0001), with a significant linear trend across dose intensities.
CONCLUSION: In a real-world experience within a large, integrated health care system, significant reductions in MACE were found in association with both any and high-intensity statin prescriptions following an ASCVD event. Temporal trends indicated progressive improvement in guideline-recommended prescriptions. However, treatment gaps remain in receipt of both any statin and, especially, a high-intensity statin prescription, and these represent prime opportunities for further improvement in secondary ASCVD prevention.
