ABSTRACT
Background: International studies show a low compliance with norms for the management of cardiovascular risk factors. Aim: To assess the prevalence of risk factors in patients admitted for a coronary or vascular event and to evaluate the proportion of patients that normalize these factors after one year of follow up. Material and Methods: Three hundred and fifty seven patients aged 64±13 years (264 males), admitted to a University Clinical Hospital for a coronary or vascular event were studied. They were educated about cardiovascular risk factors and followed by their treating physicians for a mean of 11.9±2 months. During this period, smoking habits, body mass index. blood pressure, serum lipid levels, blood glucose and the appearance of new cardiovascular events were registered. Results: One year survival was 96% (all 13 deaths were of cardiac origin). Eighty seven percent of patients were free of major cardiovascular events. At discharge from hospital and at the end of follow up 49% and 44% had a total cholesterol over 200 mg/dl respectively, 9,6% and 20,8% had systolic pressure over 140 mmHg. There was no diastolic hypertension in these patients, 27% and 31% had a body mass index over 25 kg/m2 and 2% smoked (versus 32% before the event). Conclusions: After one year of follow up, the prevalence of risk factors in patients that had suffered a cardiovascular event, continues to be high.

Background: Chagas disease is endemic in Chile. Allopurinol and itraconazole have activity against Trypanosoma cruzi and are recommended for the treatment of chronic disease in adults. Aim: To evaluate the chemotherapeutic effects of allopurinol and itraconazole using conventional and non conventional serologic test. Patients and methods: Sera of 90 patients with chonic Chagas disease were studied before and after 9 to 11 months of treatment with allopurinol or itraconazole and after two month of treatment with placebo. Indirect immunofluorescence, ELISA and Western Blot analysis were the conventional serologic tests used and antibody dependent complement mediated lysis (CoML) the non conventional test. Results: There were no differences in ELISA and indirect immunofluorescence tests before and after therapy. Antigenic recognition profiles by Western Blot showed qualitative and quantitative differences in a small number of cases. CoML showed that the greater negativity was achieved in the Chagasic group treated with allopurinol or itraconazole that had a negative xenodiagnosis before drugs treatment (35.8 and 61.6 percent, respectively). Conclusions: There is a reversion of lytic activity in sera of patients with negative xenodiagnosis before treatment, suggesting the parasitemia could be an important parameter to be considered in the chemotherapy of Chagas disease
