OBJECTIVES: To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment. METHODS: This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase. ClinicalTrials.gov: NCT01791764 RESULTS: The overall in-hospital mortality rate was 5.8%. Compared with patients who survived, patients who died were more likely to be older, have higher rates of diabetes and chronic renal failure, have a lower left ventricular ejection fraction, and demonstrate more evidence of heart failure (Killip class III or IV). Patients who died had significantly lower rates of successful thrombolysis (39% vs. 68%; p = 0.005) and final myocardial blush grade 3 (13.0% vs. 61.9%; p<0.0001). Based on the multivariate analysis, the Global Registry of Acute Coronary Events score (odds ratio 1.05, 95% confidence interval (CI) 1.02-1.09; p = 0.001), left ventricular ejection fraction (odds ratio 0.9, 95% CI 0.89-0.97; p = 0.001), and final myocardial blush grade of 0-2 (odds ratio 8.85, 95% CI 1.34-58.57; p = 0.02) were independent predictors of mortality. CONCLUSIONS: In this prospective study that evaluated patients with ST-segment elevation myocardial infarction treated by a pharmacoinvasive strategy, the in-hospital mortality rate was 5.8%. The Global Registry of Acute Coronary Events score, left ventricular ejection fraction, and myocardial blush were independent predictors of mortality in this high-risk group of acute coronary syndrome patients.

No presente relato, que descreve a gestação de paciente portadora de arterite de Takayasu, serão avaliadas a interação dessa afecção com a gravidez e as intercorrências materno-fetais, do parto e do recém-nascido.

We describe here the pregnancy follow-up and outcome in a patient with Takayasu's arteritis, with a detailed account of the complications during gestation and delivery and the impact of the disease on the newborn's health.

OBJETIVO: Analisar os resultados imediatos da operação para revascularização do miocárdio sem circulação extracorpórea em pacientes acima de 75 anos. MÉTODOS: De janeiro 2001 a dezembro 2003, 193 pacientes com idade variando de 75 a 94 anos, correspondendo a 100% das operações coronarianas realizadas em pacientes acima de 75 anos, sendo 121 homens e 72 mulheres, foram submetidos a operação para revascularização do miocárdio sem circulação extracorpórea e analisados, retrospectivamente, os dados de internação dos pacientes. RESULTADOS: A hipertensão arterial esteve presente em 174 (90%), seguida de dislipidemia em 115 (59%), tabagismo em 89 (46%) e diabetes em 57 (29%), e 96 (49,7%) com antecedente de infarto do miocárdio. Destes, 53 (27,4%) tinham apresentado evento isquêmico agudo em um período < 30 dias da data da operação. Tinham lesões obstrutivas críticas em três ou mais vasos coronarianos 156 (80,95%) pacientes, enquanto 30 (15%) apresentavam obstrução do tronco da coronária esquerda e 30 (15%) apresentavam fração de ejeção < 30%. A pontuação obtida através do EUROSCORE variou de 3 a 18, com uma mortalidade esperada para o grupo de 7,54±2,69%. O número total de anastomoses distais foi de 639. Houve 7 (3,62%) óbitos, três por broncopneumonia, um por mediastinite, um por causas metabólicas, uma morte súbita após refixação de deiscência de esterno e um choque cardiogênico. Reoperação por sangramento, reintubação orotraqueal e ventilação mecânica prolongada foram fatores associados com aumento da mortalidade. CONCLUSÃO: A operação adotada para revascularização do miocárdio sem circulação extracorpórea foi associada à baixa mortalidade, baixo índice de complicações e curto período de hospitalização.

OBJECTIVE: To assess the immediate results of myocardial revascularization surgery without extracorporeal circulation in a group of patients over 75 years of age. METHODS: From January 2001 to December 2003, 193 (121 men and 72 women) patients with ages ranging from 75 to 94 years, corresponding to 100% of the coronary surgeries performed in patients over the age of 75 years, underwent myocardial revascularization without extracorporeal circulation. Their hospitalization data were retrospectively analyzed. RESULTS: Arterial hypertension was present in 174 (90%), dyslipidemia in 115 (59%), smoking in 89 (46%), and diabetes in 57 (29%). Ninety-six (49.7%) patients had had a previous myocardial infarction, 53 of whom (27.4%) had experienced an acute ischemic event in a period < 30 days after surgery. Critical obstructive lesions in 3 or more coronary vessels were present in 156 (80.95%) patients, while 30 (15%) patients had an important obstruction of the left main coronary artery, and 30 (15%) patients had an ejection fraction < 30%. The score obtained according to the EUROSCORE ranged from 3 to 18, with an expected mortality rate for the group of 7.54±2.69%. The total number of distal anastomoses was 639. Seven (3.62%) patients died, 3 due to bronchopneumonia, 1 due to mediastinitis, 1 due to metabolic causes, 1 due to cardiogenic shock, and another died suddenly after refixation of a sternal dehiscence. Reoperation due to bleeding, orotracheal reintubation, and prolonged mechanical ventilation were factors associated with an increase in mortality. CONCLUSION: The surgery adopted for myocardial revascularization was associated with a low mortality rate, a low complication index, and a short length of stay at the hospital.
