Clinical Relationship Between Chagas' Disease And Primary Arterial Hypertension In An Outpatient Reference Service [interação Clínica Entre Moléstia De Chagas E Hipertensão Arterial Primária Em Um Serviço De Referênda Ambulatorial]

Purpose - To evaluate the clinical relationship between Chagas' disease and primary arterial hypertension. Methods - The study involved 878 chronic chagasic outpatients followed by the Chagas' Disease Study Group of the University Hospital (Unicamp), over a 15-year period. Initially, the age, gender, race, clinical form of Chagas' disease and the presence of hypertension were noted for each patient. Subsequently, the data for matched hypertensive and normotensive chagasic patients were compared. Results - Of the chagasic patients 37% were hypertensive, of those, 65% had some form of heart disease compared to 49% in the normotensive group. Of those patients with Chagas' disease and arterial hypertension, 41%were blacks and 35% were caucasians. Fifty percent of the hypertensive chagasic patients were over 45 years old compared to only 29% of the non-hypertensive patients. Conclusion - Most of the hypertensive chagasic patients were 45 or more years old and showed some degree of heart failure compared to the normotensive group.706431434Palmero, H.A., Caeiro, T.F., El desafio de la enfermedad de Chagas (1982) Medicina, 42, pp. 69-75Gallo Jr., L., Morelo, F.J., Maciel, B.C., Marin-Neto, J.A., Barreto, L.E.M., Lima, F.E.C., Functional evaluation of sympathetic and parasympathetic system in Chagas' disease using dynamic exercise (1987) Cardiovasc Res, 21, pp. 922-927Soato, G.G., Vichi, F.L., Neto, A.R., Macedo, R.R., Carvalho, D.S., Prevalência de hipertensão arterial em grupos de pacientes chagásicos e não chagásicos em população de hospital geral (1974) Rev Paul Med, 84, pp. 121-123Mediado Faria, M.A., Yasuda, M.A.S., Araujo, M.J.O., Lancarotte, I., Capano, E.A., Ruiz Neto, P.P., Formas clínicas da doença de Chagas na Grande São Paulo (1982) Arq Bras Cardiol, 38, pp. 99-109Guariento, M.E., Ramos, M.C., Gontijo, J.A.R., Carvalhal, S.S., Doença de Chagas e hipertensão arterial primäna (1993) Arq Bras Caidiol, 60, pp. 71-75Frolich, E.D., Grim, C., Labarthe, D.R., Maxwell, M.H., Perloff, D., Heidman, W.H., Recommendations for human blood pressure determination by sphygmomanometers (1988) Hypertension, 2, pp. 209A-22AOparil, S., Arten al hypertension (1992) Cecil Textbook of Medicine 19th Ed, pp. 253-269. , Wyngaarden JB, Smith LH, Bennett JC, ed Philadelphia: WB SaundersFuchs, F.D., Moreira, L.B., Moraes, R.S., Bredemeier, M., Cardozo, S.C., Prevalência de hipertensão arterial sistêmica e fatores associados na região urbana de Porto Alegie.
