Clinical relationship between Chagas' disease and primary arterial hypertension in an outpatient reference service

Maria Elena Guariento et al. José Eduardo Bagnara Orosz José Antonio Rocha Gontijo

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.

Contribution of Doppler echocardiography to the evaluation of systolic and diastolic function of obese women versus a control group

Nathan Herszkowicz et al. Alfonso Barbato Waldir Salvi Daniel Pinheiro … Denise Pantaleão Alfredo Halpern Giovani G. Cerri

OBJECTIVE: To study by doppler echocardiography the cardiac systolic and diastolic functions of health, uncomplicated obese subjects. METHODS: Fifty-nine obese women with an average body mass index (BMI) of 35 kg/m² were evaluated and compared with 19 subjects with an average BMI of 23 kg/m² (control group). RESULTS: In the obese group, a clear tendency was observed toward higher systolic pressure, increased wall thickness and, consequently, myocardial mass, elevation on the circumference stress of the left ventricular wall, and an indisputable presence of diastolic abnormalities. Filling abnormalities were observed with impaired relaxation, with prolonged isovolumic relaxation time (IVRT) and augmented atrium contribution representing early indexes of cardiac dysfunction when systolic performance is still normal. CONCLUSION: Obesity is generally a chronic condition, and doppler echocardiography can be used as a noninvasive instrument for early evaluation of left ventricular diastolic indexes.
