['Chagas disease (CD) has been associated with an elevated risk of stroke, but current data are conflicting and prospective controlled studies are lacking. We performed a systematic review and meta-analysis examining the association between stroke and CD.', 'Pubmed, Embase, Cochrane Central, Latin American database, and unpublished data were searched with the use of the following terms: ("Chagas" OR "American trypanosomiasis") AND ("dilated" OR "ischemic" OR "idiopathic" OR "nonChagasic" OR "stroke" OR "cerebrovascular"). We included studies that reported prevalence or incidence of stroke in a CD group compared with a non-CD control group. Odds ratios (ORs) and their 95% confidence intervals (CIs) were computed with the use of a random-effects model.', 'A total of 8 studies and 4,158 patients were included, of whom 1,528 (36.7%) had CD. Risk of stroke was elevated in the group of patients with CD (OR 2.10, 95% CI 1.17-3.78). Similar results were observed in a subanalysis of cardiomyopathy patients (OR 1.74, 95% CI 1.02-3.00) and in sensitivity analysis with removal of each individual study. Furthermore, exclusion of studies at higher risk for bias also yielded consistent results (OR 1.70, 95% CI 1.06-2.71). Subanalysis restricted to studies that included patients with the indeterminate form found no significant difference in the stroke prevalence between CD and non-CD patients (OR 3.10, 95% CI 0.89-10.77).'] Is chagas cardiomyopathy associated with higher incidence of stroke : a meta-analysis of observational studies?
