Ischemic stroke risk factors during Greek economic crisis.

BACKGROUND: The impact of Greece's economic crisis on healthcare is of great concern. The aim of the present study was to assess the impact of economic crisis on the prevention of cerebral ischemic events. METHODS: Retrospective analysis of patients with ischemic stroke (IS) or transient ischemic attack (TIA) admitted to a tertiary neurological department in northwestern Greece during the period 2008-2014. Using 2011 as the transitional year IS/TIA patients were dichotomized according to their admission date in two subgroups: the "before economic crisis" subgroup and the "after economic crisis" subgroup. Logistic regression analyses were performed to identify predictor variables of statin/antihypertensive pretreatment. RESULTS: Patients admitted after the economic crisis outbreak (mean age: 57.6 ± 13.5 years) were found to have lower waist periphery measurements (p = 0.001), lower incidence of diabetes (p = 0.028), hyperlipidemia (p = 0.002) and metabolic syndrome(p < 0.001), at stroke onset with lower rates of antilipidemic treatment prescription prior to stroke onset compared to those patients with cerebral ischemia that were hospitalized before the financial crisis (mean age: 59.6 ± 11.1 years). However, between the two subgroups were no significant differences in the rates of untreated patients with hyperlipidemia (p = 0.189) and/or hypertension (p = 0.313). Even though statin pretreatment prior to stroke onset was found to be reduced during economic crisis compared to the period before the crisis, (OR = 0.58, 95%CI: 0.34-0.95, p = 0.032), this association did not retain statistical significance in the multivariate logistic regression analysis (OR = 1.69, 95%CI = 0.83-3.42, p = 0.143). CONCLUSIONS: Our study supports that at present financial crisis has not significantly affected the prevention of cerebrovascular events in the citizens of a provincial city area. Data from other regions and time-periods are needed for the final verdict.

Association of TNF-857C>T, TNFRSF1A36A>G, and TNFRSF1B676T>G Polymorphisms with Ischemic Stroke in a Greek Population.

Background. The role of genetic factors in the predisposition to develop ischemic stroke has been assessed by previous studies. The main goal of the current study was to determine any possible role of TNF-857C>T,TNFRSF1A36A>G, and TNFRSF1B676T>G polymorphisms in risk for stroke. Materials and Methods. One hundred seventy-three patients with first ever ischemic stroke of solely atherosclerotic etiology in Northwest Greece and a control group of 179 healthy unrelated subjects were evaluated. Results. TNFα-857TT, TNFR136AA, and TNFR2676TT genotypes were significantly increased in the patient group compared to controls (P = .008, OR = 2.47 (1.26-4.84), P = .005, OR = 1.97 (1.22-3.17), and P = .003, OR = 2.2 (1.43-3.37), resp.). In addition, the TNFR136A and the TNFR2676T alleles were found significantly increased in patients compared to controls (P = .009, OR = 1.48 (1.1-2) and P = .001, OR = 1.75 (1.25-2.46), resp.). Conclusion. The high incidence of these genotypes and alleles in patient group suggests that they are potentially predisposing factors for stroke in the Greek population studied. Large-scale multicenter controlled studies are needed to verify these polymorphisms effects on stroke susceptibility.
