Résumé

OBJECTIVE: To identify the clinical and demographic predictors of in-hospital mortality in acute myocardial infarction with elevation of the ST segment in a public hospital, in the city of Fortaleza, Ceará state, Brazil. METHODS: A retrospective study of 373 patients experiencing their first episode of acute myocardial infarction was carried out. Of the study patients, 289 were discharged from the hospital (group A) and 84 died (group B). Both groups were analyzed regarding: sex; age; time elapsed from the beginning of the symptoms of myocardial infarction to assistance at the hospital; use of streptokinase; risk factors for atherosclerosis; electrocardiographic location of myocardial infarct; and Killip functional class. RESULTS: In a univariate analysis, group B had a greater proportion of the following parameters as compared with group A: non-Killip I functional class; diabetes; age >70 years; infarction of the inferior wall associated with right ventricular impairment; time between symptom onset and treatment at the hospital >12 h; anteroseptal or extensive anterior infarction; no use of streptokinase; and no tobacco use. In a multivariate logistic regression analysis, only non-Killip I functional class, diabetes, and age >70 years persisted as independent factors for death. CONCLUSION: Non-Killip I functional class, diabetes, and age >70 years were independent predictors of mortality in acute myocardial infarction with elevation of the ST segment

Résumé

A partir do registro de prolapso da valva mitral em 28 crianças, pelo ecocardiograma bidimensional, os autores analisaram o ECG obtido. Além de dados conhecidos, verificaram desvio do AQRS para a esquerda (+30- a - 15- no plano frontal), como achado mais significativo, presente na grande maioria do tipo considerado "primário" (65,2%). Baseados na caracterizaçäo dos bloqueios divisionais do ramos direito do feixe de His, os autores discutem uma possivel explicaçäo para o fato

Résumé

Descreve-se curioso achado eletrocardiográfico em gêmeas conjugadas e discute-se esta ocorrência, que é comparável à parassistolia ou dissociaçäo atriais, encontrada também no transplantado cardíaco

Résumé

Menino de 10 anos desenvolveu quadro de infarto do miocárdio por atrite coronária. As causas mais comuns deste evento na infância säo analisadas e a inespecificidade do processo inflamatório do caso é discutida. Näo foi possível estabelecer a natureza da doença. A importância da valorizaçäo de dor precordial em crianças por doença coronária é sublinhada
