Influencing factors of hemorrhagic transformation in non-thrombolysis patients with cerebral infarction.

OBJECTIVES

Hemorrhagic transformation (HT) is a serious complication of acute cerebral infarction. The aim of study is to investigate the influencing factors of HT in non-thrombolysis patients with acute cerebral infarction, and to explore its clinical significance.

PATIENTS AND

METHODS

From June 2016 to March 2017, a total of 346 non-thrombolysis patients with acute cerebral infarction hospitalized in the Department of Neurology of Guangdong Second Provincial General Hospital, were chosen and randomly devided into the non-HT group (control) and HT group. A record of 17 indices including the patients'age, gender, hypertension, diabetes, dyslipidemia, hyperhomocystinemia, atrial fibrillation, drinking or smoking, anticoagulation, antithrombosis, international normalized ratio (INR) and platelet count were measured. Then regression analysis was made to find the independent factors for HT.

RESULTS

It was found that 38 of non-thrombolysis patients with acute cerebral infarction involved in this study were with HT. The indices including dyslipidemia, drinking, atrial fibrillation, antiplatelet aggregation, anticoagulation, INR > 1.7, cholesterin, triglyceride and platelet count showed statistical differences between the HT group and the non-HT group (P < 0.05). According to the binary logistic regression analysis, there was a negative correlation between dyslipidemia and HT (odds ratio (OR)=0.371, 95% confidence interval (CI) 0.186-0.740, P = 0.005), while there was a positive correlation between atrial fibrillation (OR=2.476, 95% CI 1.140-5.377, P=0.022), platelet count (OR=1.006, 95% CI 0.682-1.611, P = 0.007), INR>1.7 (OR=10.889, 95% CI 4.760-24.910, P = 0.000) and HT.

CONCLUSION

There is independent correlation between dyslipidemia, atrial fibrillation, platelet count, INR > 1.7 and HT. Dyslipidemia is the protective factor for HT, and atrial fibrillation, platelet count, INR > 1.7 are the risk factors for HT.
