Chagas disease is an independent risk factor for stroke: baseline characteristics of a Chagas Disease cohort.

Abstract

Chagas disease (CD) is frequently associated with cardioembolic stroke in South America. Our objective was to identify the predictors of stroke in a region where CD is endemic. We screened 305 consecutive cardiopathy patients. Significant predictors of stroke in univariable analyses were included in a multivariable model. Stroke was more frequent in CD (15.0%) compared with other cardiopathies (6.3%; P=0.015). Other predictors of stroke in univariable analyses were previous diabetes or cardioversion and use of amiodarone, antiplatelet agents, and warfarin. In multivariable analysis, remaining predictors of stroke were CD (odds ratio [OR], 1.09; 95% CI, 1.02 to 1.17), cardioversion (OR, 1.07; 95% CI, 1.02 to 1.13), and diabetes (OR, 1.12; 95% CI, 1.01 to 1.24). In conclusion, CD is a risk factor for stroke, independent of systolic dysfunction or presence of cardiac arrhythmias.
