title: High Serum Alkaline Phosphatase Levels in Relation to Multi-Cerebral Microbleeds in Acute Ischemic Stroke Patients with Atrial Fibrillation and/or Rheumatic Heart Disease.
abstract: Elevated alkaline phosphatase (ALP) levels are associated with cerebral small vascular diseases, such as silent brain infarction and cerebral white matter hyperintensity (cWMH), but few prospective data are available for cerebral microbleeds (CMBs). The aim of the study was to investigate associations between serum ALP levels and CMBs in acute ischemic stroke patients with atrial fibrillation and/or rheumatic heart disease. This prospective study involved consecutively recruited acute ischemic stroke patients with atrial fibrillation and/or rheumatic heart disease treated at two large tertiary care hospitals in southwestern China. We used logistic regression to examine the relationships between ALP levels and CMBs. Of 128 patients (56 males; mean age, 68 years) included, 71 (55.5%) patients had CMBs. Compared with the first tertile of ALP concentration, participants in the third tertile were 3.59 times more likely to have multi-CMBs (≥2) [95% confidence interval (CI): 1.21-10.71; P = 0.02] after adjusting for age, gender, smoking habits, drinking habits, ALT (alanine transaminase) levels, AST (aspartate transaminase) levels, renal impairment and cWMH.
