•Adipokines may be involved in acute ischemic stroke (AIS) (within 24 h).•Higher visfatin and lower vaspin and ghrelin serum levels are associated with AIS.•Visfatin and ghrelin may be independent predictors of AIS.•Carotid stenosis and AIS showed pronounced effects on vaspin, visfatin and ghrelin.•Admission visfatin levels in AIS patients correlated with cardiovascular death/stroke/MI during follow-up.
This study evaluated serum levels of novel adipokines in acute ischemic stroke (AIS) and their association with prognosis. We enrolled 168 patients with AIS and 58 stroke-free age- and sex-matched individuals (controls). Clinical parameters, carotid ultrasound, metabolic profile, vaspin, apelin, visfatin, and ghrelin were assayed. Stroke-patients were sampled at hospital admission and were prospectively followed-up (median 16 months) for the cardiovascular endpoint (cardiovascular death/stroke/myocardial infarction). At admission, stroke-patients appeared with higher levels of systolic blood pressure, hsCRP and worse metabolic profile (p < 0.05), (p > 0.05). Compared to controls, AIS group had significantly higher serum concentrations of visfatin (22.92 ± 9.72 ng/ml vs 16.56 ± 7.82 ng/ml, p = 0.006) and lower of vaspin (0.94 ± 0.43 ng/ml vs 1.84 ± 0.82 ng/ml, p = 0.019) and ghrelin (3.47 ± 1.44 ng/ml vs 5.93 ± 2.78 ng/ml, p < 0.001), while apelin did not differ between groups. Similar differences in adipokines were found between stroke subgroups with and without significant ipsilateral carotid stenosis (>50%) (p < 0.05). In stepwise logistic regression analysis adjusted for diabetes, hypertension, dyslipidemia and age, visfatin (p = 0.026) and ghrelin (p = 0.012) proved to be independent predictors of AIS. During follow-up, 27 patients achieved cardiovascular endpoint. In addition to coronary artery disease and NIHSS score, visfatin serum levels was associated with cardiovascular endpoint (HR: 1.255, 95% CI: 1.025–1.576). Our results suggested the association of AIS with higher visfatin and lower vaspin and ghrelin serum levels. Visfatin levels can be a predictor of cardiovascular mortality and morbidity in AIS.
