Objective: To ascertain the risk of a new vascular event (NVE) occurring after ischemic stroke and evaluate differences in risk based on stroke subtype.
Methods: This was a prospective observational study of consecutive patients with nonfatal stroke recruited at a single tertiary stroke center with follow-up ranging from 2 to 5 years (average, 31 ± 15.9 months). An NVE (vascular death, nonfatal stroke or myocardial infarction, and hospitalization for other atherothrombotic events) was defined according to criteria used in a previously developed large multicenter register of atherothrombotic patients (Reduction of Atherothrombosis for Continued Health Registry [REACH]). We analyzed age, sex, and atherosclerotic burden (AB) based on a number of vascular risk factors, affected vascular areas, and stroke subtype according to Stop Stroke Study Trial of Org 10172 in Acute Stroke Treatment (SSS-TOAST) criteria in cardioaortic, large artery atherosclerosis (LAA), unclassified (more than one causal mechanism), small-artery disease (SAD), and undetermined (without cause) stroke categories.
