Abstract

Introduction: Limited information is available on race based stroke outcomes among patients with metabolic syndrome.Methods: We conducted a retrospective review of acute ischemic stroke patients between 2008 and 2015 who were admitted to stroke service at a comprehensive stroke center. Patients were categorized to have metabolic syndrome if they have three of the four criteria (history of hypertension or diabetes or triglycerides ≥ 150 mg/dl or high density lipoprotein (HDL) < 50 mg/dl for women or < 40 mg/dl for men). Patients with metabolic syndrome were grouped based on their race. Primary outcome was modified Rankin Scale score at discharge. Secondary outcomes measures were neurological worsening, hospital mortality, in-hospital complications, discharge stroke scale, and length of stay.Results: Total 659 patients were found to have metabolic syndrome. Among these patients, 206 (31%) were non-black and 453 (69%) were of black race. Compared to non-black patients with metabolic syndrome, black patients were more likely to be women (56% vs. 35%, p<0.0001) and have a prior history of stroke (55% vs. 35%, p<0.0001). Median admission diastolic blood pressure was higher among blacks compared to non-blacks (92 vs. 87mmHg, p = 0.0093). Higher proportion of black patients were on anti-platelets (67% vs. 56%, p = 0.01), statins (83% vs. 71%; p =0.001), and anti-hypertensive medications at home (90% vs. 81%, p = 0.001). Non-blacks had higher triglycerides (188 vs. 132 mg/dl, p<0.0001) and lower HDL levels (36 vs. 44 mg/dl, p< 0.0001). There was no difference in discharge modified Rankin Scale score among the groups. In-hospital myocardial infarction was significantly more frequent among non-blacks (9% vs. 4%, p = 0.03). In-hospital mortality was significantly higher in the non-black group (11% vs. 6%, p = 0.02).Conclusion: Non-black race was associated with higher in-hospital mortality among patients with metabolic syndrome admitted for stroke. Further exploration of higher mortality among this group of patients is warranted to improve stroke outcomes.
