[Clinical presentation of chronic Chagas disease in elderly individuals]. / Apresentação clínica da doença de Chagas crônica em indivíduos idosos.

This study had the aim of evaluating the clinical presentation of chronic Chagas disease among the elderly. It was a retrospective analysis of clinical records at an outpatient referral service. The sample was divided into two groups: elderly (>or= 60 years old) and non-elderly. Sex, comorbidities, clinical form, electrocardiogram and serological titers were evaluated. In the elderly group (61 cases), the mean age was 66.03+/-5 years; 67.2% were female; 59% presented comorbidities (most frequently systemic arterial hypertension, in 39.3%); 1.6% had the indeterminate clinical form, 88.5% the cardiac form and 36% the digestive form; and abnormalities were frequently found on electrocardiograms: 41% presented anterosuperior left bundle branch block (AS-LBBB), 32.8% presented right bundle branch block (RBBB) and 22.9% presented ventricular ectopic beats (VEB). In the non-elderly group (61 cases), the mean age was 39.30+/-8.36 years; 54.1% were female; 50.8% presented comorbidities (most frequently systemic arterial hypertension, in 26.2%); 18% had the indeterminate clinical form (p<0.05), 78.7% the cardiac form and 32.8% the digestive form; and abnormalities were frequently found on electrocardiogram: 24.6% presented AS-LBBB, 21.3% RBBB and 18% VEB. It was concluded that there were no clinical differences between elderly and non-elderly Chagas patients. The indeterminate clinical form predominated in patients less than 60 years old.

Apresentação clínica da doença de Chagas crônica em indivíduos idosos / Clinical presentation of chronic Chagas disease in elderly individuals

Com o objetivo de avaliar a apresentação clínica da doença de Chagas em idosos foi realizado estudo retrospectivo utilizando-se os prontuários de doentes atendidos em ambulatório de referência. A casuística foi dividida em idosos (> 60 anos) e não idosos. Avaliou-se: sexo, co-morbidades, forma clínica, eletrocardiograma e títulos das sorologias. Idosos (61 casos): média de idade de 66,0 ± 5 anos, 67,2 por cento do sexo feminino; comorbidades em 59 por cento, mais freqüente a hipertensão arterial sistêmica (HAS)= 39,3 por cento; forma indeterminada= 1,6 por cento, forma cardíaca= 88,5 por cento, forma digestiva= 36,1 por cento; alterações freqüentes no eletrocardiograma: bloqueio divisional ântero-superior esquerdo (BDASE)= 41 por cento, bloqueio completo de ramo direito (BCRD)= 32,8 por cento, extra-sístole ventricular (EV)=22,9 por cento. Não idosos (61 casos): média de idade: 39,30±8,36 anos, 54,1 por cento do sexo feminino; comorbidades em 50,8 por cento, mais freqüente a HAS (26,2 por cento); forma indeterminada= 18 por cento (p<0,05), forma cardíaca= 78,7 por cento, forma digestiva= 32,8 por cento; alterações freqüentes no eletrocardiograma: BDASE= 24,6 por cento, BCRD= 21,3 por cento, EV =18 por cento. Concluindo, não houve diferenças clínicas entre indivíduos idosos e não idosos e a forma indeterminada predominou nos indivíduos abaixo dos 60 anos.
