The diagnosis of infection was performed by the complement fixation test, molecular methods (PCR), and, in some cases, indirect haemagglutination and xenodiagnosis. The patients with Chagas disease were classified according to clinical and electrocardiographic (ECG) characteristics [10] as asymptomatic patients without cardiac symptoms (Group A: n = 30, 57% men, 43% women; age range: 33-54 years), patients with arrhythmia-related symptoms (mild heart disease or Group B: n = 30, 57% men, 43% women; age range: 54-65 years), and patients with overt congestive heart failure (severe heart disease or Group C: n = 36, 72% men, 28% women; age range: 65-86 years).
In this phase, it is possible to detect specific antibodies by different serological tests and, in many patients, the parasites can be isolated by blood culture or by xenodiagnosis. These tests are routinely used for parasitological exams (WHO 2013).
