  • AVC isquémico pericateterismo cardíaco: a propósito de um caso clínico
    Publication . Magno, P; Loureiro, J; Marques, A; Abreu, PF; Cândido, M; Leal, P; Gil, VM
    O AVC isquémico ocorre em 0,2 a 0,4% dos doentes submetidos a cateterização cardíaca esquerda, sendo responsável por 5-10% da mortalidade relacionada com o procedimento. Estão identificados alguns factores predisponentes para esta complicação como sejam o sexo feminino, a presença de placas de aterosclerose complexas na aorta ascendente e/ou de doença arterial periférica. A oportunidade de intervenção dentro da janela de reperfusão reforça a estratégia de uma vigilância clínica rigorosa no período imediato pós-cateterização. O Cardiologista deve estar bem familiarizado com as diferentes modalidades da terapêutica de reperfusão e suas indicações de acordo com a relação temporal do AVC isquémico com o cateterismo, devendo essa decisão ser partilhada com a Neurologia e Neuro-radiologia.

  • Predictors of de novo atrial fibrillation in a non-cardiac intensive care unit
    Publication . Augusto, J; Fernandes, A; Freitas, PT; Gil, V; Morais, C
    OBJECTIVE: To assess the predictors of de novo atrial fibrillation in patients in a non-cardiac intensive care unit. METHODS: A total of 418 hospitalized patients were analyzed between January and September 2016 in a non-cardiac intensive care unit. Clinical characteristics, interventions, and biochemical markers were recorded during hospitalization. In-hospital mortality and length of hospital stay in the intensive care unit were also evaluated. RESULTS: A total of 310 patients were included. The mean age of the patients was 61.0 ± 18.3 years, 49.4% were male, and 23.5% presented de novo atrial fibrillation. The multivariate model identified previous stroke (OR = 10.09; p = 0.016) and elevated levels of pro-B type natriuretic peptide (proBNP, OR = 1.28 for each 1,000pg/mL increment; p = 0.004) as independent predictors of de novo atrial fibrillation. Analysis of the proBNP receiver operating characteristic curve for prediction of de novo atrial fibrillation revealed an area under the curve of 0.816 (p < 0.001), with a sensitivity of 65.2% and a specificity of 82% for proBNP > 5,666pg/mL. There were no differences in mortality (p = 0.370), but the lengths of hospital stay (p = 0.002) and stay in the intensive care unit (p = 0.031) were higher in patients with de novo atrial fibrillation. CONCLUSIONS: A history of previous stroke and elevated proBNP during hospitalization were independent predictors of de novo atrial fibrillation in the polyvalent intensive care unit. The proBNP is a useful and easy- and quick-access tool in the stratification of atrial fibrillation risk.
