The aim of this study was to compare the frequency of precordialgia between chagasic and non-chagasic women. A cross-sectional study comprised 647 female aged 340, chagasic (n = 362) and controls (n = 285) was done at a Brazilian university hospital. Chagasic were classified as cardiac (n = 179), megas (n = 58) or indeterminate (n = 125) clinical forms. Chest pain was ascertained by typical or atypical retrosternal pain. Age (57.0 ± 11.3 vs 57.3 ± 10.4 years), and percentage of white women (75.8% vs 77.1%) were similar between chagasic and controls, respectively. Chest pain was more prevalent (p < 0.01) among chagasic (14.6%) than controls (5.6%), mainly in the cardiac form (relative risk = 2.41; range: 1.38-4.23), a phenomenon possibly related to cardiac parasympathetic denervation and myocardial microvascular changes.
