Introduction: While cardiovascular (CV) event rates in the U.S. are declining, there is limited data on CV event rates among those with prevalent atherosclerotic CV disease (ASCVD).
Methods: Using MarketScan Research data, we identified adults ≥ 20 years with prevalent ASCVD (defined as coronary heart disease [CHD], cerebrovascular disease, or peripheral arterial disease) and at least 2 years of continuous enrollment prior to a first contact with the healthcare system in 2012. We estimated one-year Kaplan-Meier rates for: all-cause death; hospitalization for myocardial infarction (MI) or unstable angina; or hospitalization for non-hemorrhagic stroke or transient ischemic attack). Results were summarized overall and among pre-specified subgroups. Due to different age distributions, commercially insured and Medicare patients were analyzed separately.
Results: We identified 829,498 patients, including 364,330 commercially insured (mean age 55.5 yrs) and 465,168 Medicare patients (mean age 77 yrs). Overall, 31.3% had diabetes. CHD was present in 64.6%, and 4.2% had an MI in the past year. Figure 1 shows one-year event rates by subgroups.
Discussion: Contemporary rates of CV events in patients with ASCVD remain high. Recurrent ASCVD event rates vary significantly by age, sex, diabetes status, and type of CHD.
