A 56-year-old woman with well-documented Chagas disease was found to have a spontaneous type 1 electrocardiographic (ECG) pattern of Brugada syndrome. It is most likely that this characteristic ST-segment elevation is an unusual manifestation of the pathological changes in Chagas disease. This ECG pattern has been found with other cardiac pathology and has been reported to be induced in patients with Chagas disease.
BackgroundClinical in-stent restenosis (CISR) is the main limitation of coronary angioplasty with stent implantation.ObjectiveDescribe the clinical and angiographic characteristics of CISR and the outcomes over a minimum follow-up of 12 months after its diagnosis and treatment.MethodsWe analyzed in 110 consecutive patients with CISR the clinical presentation, angiographic characteristics, treatment and combined primary outcomes (cardiovascular death, nonfatal acute myocardial infarction [AMI]) and combined secondary (unstable angina with hospitalization, target vessel revascularization and target lesion revascularization) during a minimal follow-up of one year.ResultsMean age was 61 ± 11 years (68.2% males). Clinical presentations included acute coronary syndrome (ACS) in 62.7% and proliferative ISR in 34.5%. CISR was treated with implantation of drug-eluting stents (DES) in 36.4%, Bare Metal Stent (BMS) in 23.6%, myocardial revascularization surgery in 18.2%, balloon angioplasty in 15.5% and clinical treatment in 6.4%. During a median follow-up of 19.7 months, the primary outcome occurred in 18 patients, including 6 (5.5%) deaths and 13 (11.8%) AMI events. Twenty-four patients presented a secondary outcome. Predictors of the primary outcome were CISR with DES (HR = 4.36 [1.44–12.85]; p = 0.009) and clinical treatment for CISR (HR = 10.66 [2.53–44.87]; p = 0.001). Treatment of CISR with BMS (HR = 4.08 [1.75–9.48]; p = 0.001) and clinical therapy (HR = 6.29 [1.35–29.38]; p = 0.019) emerged as predictors of a secondary outcome.ConclusionPatients with CISR present in most cases with ACS and with a high frequency of adverse events during a medium-term follow-up.
Introduction and objective: infectious endocarditis (IE) is a disease with high morbidity and mortality despite improvements in diagnosis and antimicrobial therapy. The early identification of patients at high risk of death or complications can improve the outcome of this disease. The objective was to analyze IE cases in a tertiary hospital and their in-hospital outcomes. Patients and methods: 93 episodes of IE were retrospectively analyzed in 91 patients, between January of 2001 and December of 2008. The analyzed variables were: clinical and infectious data, therapeutic modality, and outcomes during hospital developments. The statistical analysis employed the Chi-square, odds ratio, and Mann-Whitney tests. Results: the in-hospital mortality occurred in 35% (IC 95%; 26-41%), valve prostheses were involved in 60.23% of cases, and blood cultures without isolation occurred in 36.56%. In positive blood cultures, the main etiological agent isolated was Staphylococcus aureus in 31.18%, multi sensitive S. aureus in 22.8%, and S. aureus MARSA in 8.6%. Surgical intervention was performed in 48.39% of the patients and the main surgical indicator was failure of clinical treatment (20.43%) Patients who have had ICC as outcome presented 57.14% mortality (p = 0.004 and OR of 3.76, IC 95%; 1.41-10.03); mortality rate of 66.67% as observed in those with pacemakers as the site of infection. Conclusions: IE remains with high morbidity and mortality. Mortality rates vary according to the etiological agent, prior cardiac state, site of infection, and increased age.
Os relatos científicos a respeito da isquemia arterial mesentérica sugerem que essa doença é pouco entendida, muito pouco diagnosticada e raramente tratada, apesar de sua alta letalidade. O prognóstico da isquemia mesentérica dependerá do rápido restabelecimento do fluxo sanguíneo, seja por meio de medidas clínicas, cirúrgicas, endovasculares ou da combinação destas. Neste artigo revisam-se as principais evidências diagnósticas da isquemia mesentérica bem como as opções terapêuticas disponíveis, incluindo a intervenção percutânea como método alternativo à cirurgia, que é associada a significativas taxas de morbidade e mortalidade.

Buscando a revascularização completa do miocárdio, 165 casos foram analisados dentre 359 pacientes submetidos a cirurgia de revascularização do miocárdio, no período de janeiro de 1995 a janeiro de 1996, com pontes de veia safena e/ou artéria torácica interna, de forma seqüencial, ou associadas como enxertos compostos. Destes, 132 receberam pontes seqüenciais de veia safena servindo a 2 ou mais ramos arteriais coronários, 25 foram tratados através de anastomoses seqüenciais de artéria torácica interna, de forma simples, interessando aos ramos interventricular anterior e diagonais da coronária esquerda, enquanto 8 receberam enxertos compostos de artéria torácica interna direita e esquerda associados a segmentos de veias safenas, que terminavam em ramos das artérias coronárias direita e esquerda. Em 96% os casos a operação programada foi realizada, obtendo-se revascularização completa. Ocorreu um único (0,6%) óbito hospitalar conseqüente a infarto do miocárdio transoperatório, seguido de síndrome de baixo débito cardíaco; a morbidade não diferiu daquela presente nos procedimentos usuais de revascularização cirúrgica do miocárdio. Os cuidados na dissecção e preparo dos pedículos da artéria torácica interna, bem como na retirada e preparo para implante das veias safenas, somados àqueles necessários à obtenção da perfeita anastomose seqüencial, de modo a evitar torções, angulações e acotovelamentos dos enxertos, são enfatizados como fundamentais para o excelente resultado obtido na série analisada. Nossos resultados entusiasmam o emprego da crescente freqüência no uso da técnica da revascularização completa do miocárdio.
The authors analyse 165 patients out of 359 submitted to myocardial revascularization during the period between January 1995 and January 1996, in which the saphenous veins and the internal thoracic arteries have been used as a sequential graft, or associated with a composit graft; 132 received saphenous veins as a sequential graft to two or more coronary branches, 25 had sequential anastomosis of the left internal thoracic artery to IVA and diagonal branches of the left coronary artery, and 8 cases had both saphenous veins and internal thoracic arteries used as a composite graft to branches of the left and right coronary arteries. In 96% of the cases the scheduled surgery was performed, one patient died in the immediate post-operative period (0.6%) and the morbidity was not different from that found in the standard coronary artery surgery. Details of the preparation of the grafts, as well as operative technique is discussed, and the results of this series stimulated us for further use of the sequential grafts aiming for complete myocardial revascularization
