Abstract:
The purpose of this study was to investigate the association between adiposity using adipose tissue imaging and stroke outcomes in acute ischemic stroke patients treated with intravenous thrombolysis. Methods— A total of 127 patients with acute ischemic stroke treated with intravenous thrombolysis who underwent abdominal computed tomography on admission were enrolled in this prospective cohort study. Patients were grouped according to their visceral adipose tissue (VAT) proportion tertile. The primary outcome was measured using the modified Rankin Scale 3 months after symptom onset. Favorable and excellent outcomes were defined as modified Rankin Scale scores of 0 to 2 and 0 to 1, respectively. Results— As VAT proportion tertile increased, the number of patients exhibiting a favorable or excellent outcome decreased. In the final multivariable analysis after adjustments for confounders, patients in the highest VAT proportion tertile showed a decreased probability of a favorable and excellent outcome compared with those in the lowest tertile (odds ratio=0.18; 95% CI, 0.05−0.60; P =0.005 and odds ratio=0.13; 95% CI, 0.02−0.64; P =0.012, respectively). Obese patients (body mass index ≥25) also showed an excellent outcome compared with nonobese patients (odds ratio=4.88; 95% CI, 1.47−7.85; P =0.011). Among obese patients, those with an excellent outcome presented a significantly lower VAT proportion than those without (38.2% versus 46.1%, P =0.006). Conclusions— Results of this study indicate that low visceral abdominal fat proportion is associated with a favorable and excellent outcome in acute ischemic stroke patients treated with intravenous thrombolysis. Better clinical outcomes in obese patients were also associated with a lower proportion of VAT.
