Estudo comparativo entre pacientes infartados fumantes, ex-fumantes e näo-fumantes / Comparative study of smokers, ex-smokers, and nonsmokers who have experienced myocardial infarction

OBJECTIVE: To assess the impact of smoking on in-hospital morbidity and mortality in patients who have experienced acute myocardial infarction and to assess the association between smoking and other cardiovascular risk factors and clinical data. METHODS: A prospective cohort study analyzed 121 patients, including 54 smokers, 35 ex-smokers, and 32 nonsmokers. RESULTS: Using the chi-square test (P<0.05), an association between smoking and the risk factors sex, age, and diabetes was documented. Among the morbidity and mortality variables, only acute pulmonary edema showed a statistically significant difference (OR=9.5; 95 percent CI), which was greater in the ex-smoker group than in the nonsmoker group. CONCLUSION: An association between smoking and some cardiovascular risk factors was observed, but no statistical difference in morbidity and mortality was observed in the groups studied, except for the variable acute pulmonary edema

Hipertensäo arterial acelerada maligna associada à insuficiência renal aguda / Accelerated-malignant hypertension associated with acute renal failure

Hipertensäo arterial acelerada maligna (HAAM) é considerada uma síndrome constituída por elevaçäo acentuada da pressäo arterial, geralmente com pressäo arterial diastólica acima de 140 mmHg, associada à alteraçäo da retina e perda aguda da funçäo renal. Relatamos e discutimos um caso clínico de hipertensäo arterial acelerada maligna em jovem masculino acompanhado de insuficiência renal aguda, cuja microscopia renal mostra arterioloesclerose com endarterite.
