Background And PurposeWhite matter hyperintensities (WMHs) are associated with the presence of left ventricular hypertrophy (LVH). It is unclear if periventricular WMH (PV-WMH) and or deep WMH (D-WMH) are associated with LVH. We evaluated the association of PV-WMH and D-WMH with common transthoracic echocardiogram abnormalities, including LVH in acute ischemic stroke.MethodsPV-WMH and D-WMH were graded on a 0-3 score based on the Fazekas scale. Patients were categorized into clinically significant PV-WMH and D-WMH (score 2-3) and controls (score 0-1). Multivariate logistic regression analysis was performed to determine abnormalities on echocardiogram associated with PV-WMH and D-WMH.ResultsAmong 272 patients, 137 patients had PV-WMH and 93 patients had D-WMH with a score of 2-3 on Fazekas scale. Compared to controls, patients with PV-WMH (mean age±standard deviation: 60.8±14.4 vs. 73.8±11.2 years) and D-WMH (63.4±14.4 vs. 75.0±11.1 years) were older. Compared to controls, PV-WMH was associated with history of stroke (22 [16%] vs. 37 [27%], p = .03) and valvular calcification (33 [24%] vs. 61 [45%], p = .0005); D-WMH was associated with history of atrial fibrillation (25 [14%] vs. 22 [24%], p = .04), valvular calcification (50 [28%] vs. 44 [47%], p = .001), and LVH (30 [17%] vs. 25 [27%], p = .049). In multivariate analysis, PV-WMH was associated with age (odds ratio [OR] = 1.09; 95% confidence interval [CI] = 1.06-1.12) and stroke history (OR = 2.1; 95% CI = 1.1-4.1), and D-WMH was associated with age (OR = 1.07; 95% CI = 1.05-1.10) and LVH (OR = 2.0; 95% CI = 1.0-4.0).ConclusionLVH is associated with D-WMH but not with PV-WMH. Although valvular calcification is common, it is likely age related than due to WMH.© 2021 American Society of Neuroimaging.
