Clinical characteristics of lung cancer associated acute ischemic stroke and atrial fibrillation associated acute ischemic stroke / 中国医师杂志

ABSTRACT

Objective:To analyze the clinical characteristics of lung cancer associated acute ischemic stroke (LCA-AIS) and atrial fibrillation associated acute ischemic stroke (AFA-AIS).Methods:From January 1, 2014 to December 31, 2018, 46 patients diagnosed with LCA-AIS (LCA-AIS group)in Hainan Hospital of Chinese PLA General Hospital were selected, and 46 patients diagnosed with AFA-AIS (AFA-AIS group) were matched according to age and sex.The general situation, laboratory test results and imaging results of the two groups were analyzed.Results:(1) The neurological deficit symptoms in AFA-AIS group were more serious than those in LCA-AIS group; there was significant difference in National Institutes of Health Stroke Scale (NIHSS) score and the Modified Rankin Scale (mRs) score between the two groups ( P=0.001, P=0.003). (2)The D-D polymer concentration in LCA-AIS group was significantly higher than that in AFA-AIS group ( P<0.001), but the hemoglobin, erythrocyte count and hematocrit were significantly lower than those in AFA-AIS group (all P<0.001). (3)There was no significant difference in imaging classification and the number of infarct basins between LCA-AIS group and AFA-AIS group ( P>0.05). LCA-AIS patients was more likely to have poly-period acute ischemic lesions ( P=0.015), while AFA-AIS had significantly larger infarct diameter and more likely to be complicated with acute hemorrhagic stroke or bleeding ( P<0.001). Conclusions:The clinical characteristics of LCA-AIS and AFA-AIS are similar, so it is necessary to distinguish LCA-AIS from AFA-AIS in combination with neurological impairment, laboratory tests and imaging findings to avoid misdiagnosis.
