Correlation between cerebral microbleeds and long term aspirin administration in non-hypertensive patients / 实用放射学杂志

ABSTRACT

Objective To investigate the correlation of long term aspirin treatment and cerebral microbleeds(CMBs)incidence in non-hypertensive patients.Methods 56 non-hypertensive patients (the average age of 64.88±6.99)with long term aspirin adminis-tration (100 mg/d)were enrolled in the study from 2005 to 2010 in our hospital,with follow up to compare CMBs 5-10 years later. All patients underwent T2 WI,T1 WI,diffusion-weighted imaging (DWI)and susceptibility weighted imaging (SWI).The CMBs lesions were defined by senior radiologists.Patients’age,gender,total cholesterol level,aspirin,CMBs and CMBs location were taken into account in data analysis.Results CMBs incidence was 14.3% in all participants,lesions were located mostly in lobes.Aged,male and low total cholesterol level were the risk factors of CMBs (P0.05),the potential adverse effect of aspirin needs further investigation.
