SVD burden was defined as SVD score &gt;\u20092. ICAD was classified as normal\u2010to\u2010mild, moderate, and severe stenosis\u2010to\u2010occlusion. The outcomes were any ischemic event, ischemic stroke, major bleeding, intracranial hemorrhage, and all\u2010cause mortality. We assessed associations of ICAD with outcomes via Cox regression and mediation analyses, adjusting for SVD burden.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 5250 patients (mean age: 71\u2009\u00b1\u200911\u2009years, 33% women), 3947 (75%) received antiplatelets and 1304 (25%) anticoagulants at baseline. ICAD was normal\u2010to\u2010mild in 3781 (72%), moderate in 571 (11%), and severe\u2010to\u2010occluded in 894 (17%). SVD burden was observed in 1400 (27%). ICAD was associated with a higher frequency of non\u2010lacunar infarcts and a lower frequency of PVS. There was no graded association between ICAD severity and SVD burden. During a median follow\u2010up of 2\u2009years, 278 ischemic events, 197 ischemic strokes, 97 major bleedings, 55 intracranial hemorrhages, and 217 deaths occurred. Severe\u2010to\u2010occluded ICAD independently increased the risk of any ischemic event (adjusted hazard ratio: 1.39 [1.03\u20131.86]) and mortality (2.01 [1.48\u20132.74]); coexisting SVD burden further increased the risk of all outcomes. ICAD directly affected ischemic events, while mortality was mainly driven by its additive interaction with SVD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
