RESUMEN
We conducted a systematic review to compare the effectiveness and safety of exercise versus no exercise for patients with asymptomatic aortic aneurysm. We followed the guidelines set out in the Cochrane systematic review handbook. We searched Medline, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, ICTRP, and OpenGrey using the MeSH terms "aortic aneurysm" and "exercise". 1189 references were identified. Five clinical trials were included. No exercise-related deaths or aortic ruptures occurred in these trials. Exercise did not reduce the aneurysm expansion rate at 12 weeks to 12 months (mean difference [MD], -0.05; 95% confidence interval [CI], -0.13 to 0.03). Six weeks of preoperative exercise reduced severe renal and cardiac complications (risk ratio, 0.54; 95% CI, 0.31-0.93) and the length of intensive care unit stay (MD, -1.00; 95% CI, -1.26 to -0.74). Preoperative and postoperative forward walking reduced the length of hospital stay (MD, -0.69; 95% CI, -1.24 to -0.14). The evidence was graded as 'very low' level.
Foi realizada revisão sistemática para comparar a efetividade e a segurança de exercícios versus não exercícios em pacientes assintomáticos com aneurisma de aorta. Usamos os termos MeSH aortic aneurysm e exercise para as bases MEDLINE, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, International Clinical Trials Registry Platform (ICTRP) e OpenGrey. Foram obtidas 1.189 referências. Cinco ensaios clínicos foram incluídos. Não houve morte ou rotura associada ao exercício. Além disso, este não reduziu a velocidade de crescimento do aneurisma em 12 semanas a 12 meses [diferença de médias (DM) −0,05; intervalo de confiança de 95% (IC95%) −0,13 a 0,03]. Seis semanas de exercícios pré-operatórios reduziram complicações clínicas renais e cardíacas (razão de risco 0,54; IC95% 0,310,93) e a permanência em unidade de terapia intensiva (DM −1,00; IC95% −1,26 a −0,74). Caminhadas nos períodos pré e pós-operatório reduziram a permanência hospitalar. A evidência foi classificada como de muito baixa qualidade.
RESUMEN
Cardiac diseases are the most common cause of acute arterial emboli, however, cardiac tumors are not as frequent. Cardiac metastases from melanoma are usually silent, and rarely cause symptoms. Only a few reports are found in the literature of metastatic melanoma, causing arterial emboli. Here, we report a case of a cardiac metastasis of melanoma cancer that presented preoperative as arterial emboli. The gross appearance of the emboli already suggested the presence of a cardiac tumor. In selected patients who have a solitary intracardiac melanoma, surgical resection can provide relief from clinical symptoms and minimize potential cardiac sequelae of the tumor.
