Resumo
[Abstract]
Background and purpose: To assess whether neuroimaging markers of chronic cerebral small vessel disease (cSVDm) influence early recovery after acute ischemic stroke (AIS).
Methods: Retrospective analysis of patients diagnosed with AIS and included in the Spanish Neurological Society Stroke Database.
Inclusion criteria: (1) Brain MRI performed after acute stroke and (2) Premorbid modified Rankin scale (mRS) = 0.
Exclusion criteria: (1) Uncommon stroke etiologies, (2) AIS not confirmed on neuroimaging, or (3) Old territorial infarcts on neuroimaging. Patients scored from 0 to 2 according to the amount of cSVDm. Patients were divided into lacunar ischemic stroke (LIS) and nonlacunar ischemic stroke (NLIS) groups according to TOAST classification.
Primary outcome: Distribution of mRS at discharge.
Secondary outcomes: NIHSS improvement more than or equal to 3 at 24 hours and at discharge, NIHSS worsening more than or equal to 3 points at 24 hours.
Results: We studied 4424 patients (3457 NLIS, 967 LIS). The presence of cSVDm increased the risk of worsening 1 category on the mRS at discharge in the LIS group ([1] cSVDm: OR 1.89 CI 95% 1.29-2.75, P = .001. [2] cSVDm: OR 1.87, CI 95% 1.37-2.56 P = .001) and was an independent factor for not achieving an improvement more than or equal to 3 points on the NIHSS at discharge for all the patients and the LIS group (all stroke patients: [1] cSVDm: OR 0.81 CI 95% .68-.97 P = .022. [2] cSVD: OR 0.58 CI95% .45-.77, P = .001./LIS: [1] cSVDm: OR 0.64, CI 95% .41-.98, P = .038. [2] cSVDm: OR 0.43, CI 95% .24-.75 P = .003).
Conclusions: Pre-existing SVD limits early functional and neurological recovery after AIS, especially in LIS patients.
