Framingham score for public transportation drivers in the city of Teresina, Piauí.

OBJECTIVE: To estimate the absolute risk of the public transportation drivers in the city of Teresina, Piauí, to develop coronary heart disease over the course of ten years based on the Framingham risk score. METHODS: An observational, descriptive, cross-sectional study using the Framingham score was conducted with 107 public transportation drivers in the city of Teresina, Piauí, to assess level of risk and its association with the Framingham predictors that include: age, total cholesterol, HDL cholesterol, systolic blood pressure, diastolic blood pressure, diabetes mellitus and smoking. The significance test used was Chi2. The prevalence rate was used as the association measurement. RESULTS: Mean risk was 5% and the greatest majority of the participants were situated in the low risk category (85.05%). Mean values for the variables were: 42 years of age, total cholesterol 200 mg%, HDL cholesterol 49 mg%, systolic blood pressure 130 mmHg and diastolic blood pressure 85 mmHg. The associations between diabetes mellitus, smoking and HDL cholesterol with level of risk were not statistically significant; however other variables had a great influence on the level of risk obtained. CONCLUSION: The mean absolute risk estimate for the public transportation drivers in the city of Teresina to develop coronary heart disease over the next ten years based on the Framingham score is low. The majority of the participants in the study (85.05%) were situated in the low risk category, that is, with a relative risk less than or equal to 10%.

[Systemic hypertension at emergency units. The use of symptomatic drugs as choice for management].

OBJECTIVE: Compare the therapeutic response of symptomatic, hypertensive patients to symptomatic medication or anti-hypertensive drugs at the Emergency Unit. METHODS: A randomized, blind clinical trial involving 100 (one hundred) patients assisted at the Cardiology Emergency Unit at Oswaldo Cruz University Hospital (HUOC). All patients reported symptoms associated to systolic pressure (SBP) between 180 and 200 mmHg and/or diastolic pressure (DBP) between 110 and 120 mmHg. Patients were randomized for treatment with symptomatic (dipirone or diazepan) or anti-hipertensive drug (captopril). Those reporting any associated clinical condition and in need of immediate treatment at the Emergency Unit were excluded from the study. Patients reporting no symptoms, and systolic pressure reduced to levels under 180 mmHg and diastolic pressure under 110 mmHg after the 90-minute period were considered as having met discharge criteria. RESULTS: Mean age of population studied was 54.4 years old, most commonly females. Patients were chronic hypertensive, on irregular pharmacological treatment, with low compliance to non-pharmacologic actions, and classified as overweight and obese grade I. Headache, type D (non-angina) chest pain, and dyspnea were the most frequent complaints. The number of patients treated with symptomatic drug who reached discharge criteria was similar to that of patients treated with anti-hypertensive (p=0.165). No association was found between previous high blood pressure (HBP) diagnosis (p=0.192), pharmacological treatment (p=0.687), and non-pharmacological treatment and discharge criteria. CONCLUSION: Blood pressure (BP) was reduced below levels for discharge criteria for a (non-significant) higher rate of patients treated with symptomatic drug, who were turned into asymptomatic after the observation period.

[Measurement of human brain natriuretic peptide in patients with Chagas' disease].

OBJECTIVE: To measure the serum levels of brain natriuretic peptide (BNP) in patients with chronic chagasic heart disease and in individuals with positive serology for Chagas' disease and no heart impairment, and to correlate the serum BNP levels with the degree of cardiac impairment, cardiac dimensions, presence of a pacemaker, and ejection fraction. METHODS: Serum BNP concentrations were determined by use of the Triage-BNP Test produced by BIOSITE. Serum BNP was assessed in 25 patients from the Chagas' disease outpatient clinic of the Hospital Universitario Oswaldo Cruz, who were divided into 2 groups as follows: 1) G1--comprising 13 asymptomatic patients with positive serology for Chagas' disease and no heart disease detectable on electrocardiography, chest X-ray, and echocardiography; and 2) G2--comprising 12 patients with Chagas' disease and heart impairment. RESULTS: Significantly more elevated BNP levels were detected in the chagasic patients with cardiac impairment: (G1=4.4 +/-4.4 pg/ml, G2=293.0+/-460.2 pg/ml); (P<0.01). In the 2 groups, the serum levels of BNP correlated neither with age nor with sex. The levels were directly proportional to functional class and cardiac area on chest X-ray. Although a trend towards an increment in systolic function impairment was observed, no linear correlation with the ejection fraction on echocardiography occurred. The presence of definitive pacemaker and electrocardiographic alterations did not change the serum BNP levels. CONCLUSION: Asymptomatic individuals with a positive serology for Chagas' disease and no evidence of ventricular dysfunction have serum BNP levels similar to those of the general population.
