Abstract

BACKGROUND:

Cerebral white matter lesions (WML) are regarded as manifestations of small vessel disease, but have also been associated with large vessel atherosclerosis. We investigated whether WML have a predictive value for future ischemic events.

METHODS AND RESULTS:

Two-hundred-thirty patients with proven atherosclerotic disease, recent ischemic stroke (IS, n=70), recent myocardial infarction (MI, n=71), or peripheral arterial disease (PAD, n=89) were included. The presence of periventricular lesions (PVL) and deep white matter lesions (DWML) on MRI at entry and ischemic events during follow-up were registered. During follow-up with a mean duration of 3.5+/-1.4 years 22 patients had a MI, 21 patients suffered an IS and 2 patients died suddenly. The frequency of ischemic events during follow-up was higher among patients with PVL than in those without PVL (IS: 18% versus 5%, p=0.001; MI: 15% versus 7%, p=0.03; any ischemic event: 36% versus 11%, p<0.001). DWML was associated only with the combined outcome any ischemic event (p=0.04). In multivariate regression analysis the presence of PVL was independently associated with IS (HR 3.2 (95%CI 1.3-8.4) and MI (HR 3.4 (95%CI 1.4-8.0)).

CONCLUSION:

We observed an association between WML, especially PVL, and future ischemic strokes and myocardial infarctions in patients with established atherosclerotic disease.
