Abstract/OtherAbstract:
BACKGROUND: Cerebral microbleeds (CMBs) were found in patients with and without hypertension. We aimed to investigate different distribution patterns of CMBs in patients with and without hypertension. METHODS: We examined acute ischemic stroke patients using a standardized MRI protocol that included T(1), T(2) and gradient-echo T(2)*. Clinical and imaging characteristics were collected from all patients. RESULTS: Among 998 patients, CMBs were detected in 273 patients (27.3%). Of these, 62 did not have hypertension (22.7%). The incidence of CMBs among patients without hypertension (62/335, 18.5%) was lower than among those with hypertension (211/663, 31.8%; p < 0.01). The location of CMBs in patients without hypertension was limited to the cortical-subcortical (CSC) region in 40.3% (25/62) compared to 20.4% of those with hypertension (43/211; p = 0.01). No significant difference was found between CMB locations within the intra-CSC region in both groups. The severity of white matter changes and systolic blood pressure on admission were found to be independent predictors for CMBs in patients without hypertension. CONCLUSIONS: CMBs in patients with and without hypertension have different distribution patterns and may have a different pathogenesis. Blood pressure controlling is important in both groups because systolic blood pressure is an independent predictor of CMBs in patients without hypertension.
