Paradoxical effect of obesity on hemorrhagic transformation after acute ischemic stroke

چکیده
BACKGROUND Among the patients with established coronary artery diseases, obese patients tend to have a more favorable prognosis, which is called as obesity paradox. Interestingly, mildly obese patients who underwent coronary revascularization had a lower risk of bleeding. In this context, we have investigated the association between obesity and hemorrhagic transformation (HTf) after acute ischemic stroke. METHODS A total of 365 patients with first-ever acute ischemic stroke were included in this study. Demographic, clinical and radiological information was collected and HTf was evaluated through follow-up T2*-weighted gradient-recalled echo MRI performed usually within 1 week after occurrence of stroke. Body mass index was calculated, and obesity was defined using the World Health Organization Western Pacific Regional Office criteria. RESULTS The HTf was identified in 59 patients (16.2%). As the severity of obesity increased, the occurrence of HTf decreased. Compared with the normal weight group and after controlling possible confounders including acute and previous treatment, stroke severity and subtype, the risk of HTf decreased significantly in the obese group (odds ratio, 0.39; 95% confidence interval, 0.17-0.87). CONCLUSIONS The better outcome for HTf seen in obese patients suggests the existence of a "bleeding-obesity paradox" in acute ischemic stroke.

Investigation the frequency of asymptomatic hemorrhagic transformation of infarction in CT scan of acute ischemic stroke patients
Background: Asymptomatic hemorrhagic transformation infarct (AHTI) is known as a complication of ischemic attack and maybe occurs in the entire stroke. However, the role of AHTI in the result of the treatment is still not clear, because it is based on the definition of an asymptomatic and not identifiable. The aim of this study was assessment and evaluation frequency of AHTI in acute ischemic s...

Ischemic stroke accounts for about 87 percent of all cases. It occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. It is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. We know that most of the injuries after an acute ischemic s...
