    Young patient with a history of smoking, hypertension and use of illicit drugs (cannabis, cocaine and crack) was admitted with precordial pain after physical exercise within the previous two hours. Electrocardiogram demonstrated ST segment elevation in leads V1 to V4 and the patient was referred to cardiac catheterization, which showed total occlusion of the left anterior descending artery and a large amount of thrombi in the right coronary artery. The patient was treated with direct stenting in the left anterior descending artery and triple antiplatelet therapy with aspirin, clopidogrel and abciximab in combination with non-fractioned heparin for 24 hours. Angiography and intravascular ultrasound assessment after 48 hours demonstrated a complete resolution of thrombi in both coronary arteries.Paciente jovem, com histórico de tabagismo, hipertensão arterial e uso de drogas ilícitas (cannabis, cocaína e crack), foi admitido com dor precordial após atividade física, com cerca de duas horas de evolução. O eletrocardiograma demonstrou supradesnivelamento do segmento ST de V1 a V4, e o paciente foi encaminhado para cateterismo cardíaco, que evidenciou oclusão total da artéria descendente anterior e grande quantidade de trombos na coronária direita. Foi tratado com implante direto de stents na artéria descendente anterior e terapia antiplaquetária tripla com aspirina, clopidogrel e abciximab associada a heparina não-fracionada, mantidas por 24 horas. Reavaliações angiográfica e ultrassonográfica após 48 horas demonstraram resolução completa dos trombos em ambas as coronárias.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Setor de Hemodinâmica e Cardiologia IntervencionistaUNIFESP, EPM, Setor de Hemodinâmica e Cardiologia IntervencionistaSciEL

    Tridimensional rotational angiography (3D-RA) as a diagnostic tool for patients with transplant renal artery stenosis

    BACKGROUND: Transplant renal artery stenosis (TRAS) is the major vascular complication associated to adverse events in patients with kidney grafts, whose incidence ranges from 1% to 23%. Angiography is the gold-standard for diagnosis, enabling immediate treatment; however, due to the variable anatomy and location of anastomosis, additional projections are often required, leading to greater exposure to contrast medium and radiation. Tridimensional rotational angiography (3D-RA) appears as a tool for diagnosis and treatment of TRAS. The aim of this paper was to evaluate the accuracy of measurements obtained by 3D-RA in comparison to conventional angiography. METHODS: From April, 2010 to January, 2011, 41 3D-RAs were performed in patients with clinical suspicion of TRAS. Images were analyzed by independent observers; conventional angiography measurements were obtained online and 3D-RA measurements were obtained offline with the Philips Allure 3D-RA software. RESULTS: Thirty-five 3D-RAs (84%) were considered adequate for angiographic measurements, and 20% provided additional and relevant information for the therapeutic strategy. There was no statistically significant difference between measurements obtained from the reference diameter and minimal luminal diameter of the artery using 3D-RA and conventional angiography. In addition, there was a strong correlation between them CONCLUSIONS: 3D-RA comes up as a useful tool for TRAS diagnosis, providing accurate measurements and complementary and relevant information for the diagnosis and treatment, in addition to potentially reducing procedure time and exposure to contrast and radiation.INTRODUÇÃO: A estenose da artéria do rim transplantado (EART) é a principal complicação vascular associada a eventos adversos em pacientes portadores de enxerto renal, cuja incidência varia de 1% a 23%. A arteriografia é o padrão de referência para o diagnóstico, possibilitando tratamento imediato; porém, em decorrência da anatomia variável e da localização da anastomose, muitas vezes são necessárias projeções adicionais, levando a maior exposição ao contraste e à radiação. A angiografia rotacional com reconstrução tridimensional (tridimensional rotational angiography - 3D-RA) surge como ferramenta para o diagnóstico e o tratamento da EART. O objetivo deste estudo foi avaliar a acurácia das medidas obtidas pela 3D-RA, comparativamente à obtida pela angiografia convencional. MÉTODOS: De abril de 2010 a janeiro de 2011, foram realizadas 41 3D-RA em pacientes com alta suspeita clínica de EART. As imagens foram analisadas por observadores independentes, sendo as medidas da arteriografia convencional obtidas no momento do procedimento e as da 3D-RA, após o processamento das imagens pelo software Philips Allure 3D-RA. RESULTADOS: Foram analisadas 35 3D-RA (84%) consideradas adequadas para a realização das medidas angiográficas, das quais 20% contribuíram com informações adicionais relevantes para a estratégia terapêutica. Não houve diferença estatisticamente significante entre as medidas dos diâmetros de referência e luminal mínimo da artéria obtidas pela 3D-RA e pela angiografia convencional, além de ter havido forte correlação entre elas. CONCLUSÕES: A 3D-RA surge como ferramenta útil para o diagnóstico da EART, ao obter medidas acuradas, oferecer informações complementares e relevantes para o diagnóstico e tratamento, além de potencialmente reduzir o tempo do procedimento e a exposição ao contraste e à radiação.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Hospital São PauloUniversidade Federal de São Paulo (UNIFESP) Fundação Oswaldo Ramos Hospital do Rim e HipertensãoUNIFESP, EPM, Hospital São PauloUNIFESP, Fundação Oswaldo Ramos Hospital do Rim e HipertensãoSciEL

    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.Universidade Federal de São Paulo (UNIFESP) Department of CardiologySecretaria de Saude do Municipio de São PauloHospital Municipal TatuapeUNIFESP, Department of CardiologySciEL

    AbstractBackgroundPharmacoinvasive therapy (PIT) is feasible in patients with acute myocardial infarction with ST-segment elevation (STEMI) when timely primary percutaneous coronary intervention (PCI) is unavailable. In this study, we compared women who underwent successful reperfusion PIT with those who required rescue PCI, to identify potential predictors of thrombolytic failure.MethodsFrom January 2010 to November 2014, 327 consecutive women with STEMI were referred to a tertiary hospital, 206 after successful thrombolysis (63%) and 121 who required rescue PCI. The groups were compared regarding demographic, clinical and angiographic outcomes, and clinical (TIMI, GRACE, and ZWOLLE CADILLAC) and bleeding (CRUSADE) risk scores. A multivariate logistic regression model was used to identify predictors of thrombolytic failure.ResultsThere was no significant difference between the demographic characteristics or the medical history of the groups. Rescue PCI group had significantly higher values of the evaluated scores. Clinical hospital complications and mortality (2.5% vs. 22.0%; p < 0.0001) were more frequent in rescue PCI group. The independent variables associated with rescue PCI were pain-to-needle time > 3h (OR: 3.07, 95%CI: 1.64 to 5.75; p < 0.0001), ZWOLLE score (OR: 1.25; 95%CI: 1.14 to 1.37; p = 0.0001) and creatinine clearance (OR: 1.009, 95%CI: 1.0 to 1.02; p = 0.04).ConclusionsWomen with STEMI who underwent PIT and who required rescue PCI had significantly higher mortality compared to those who achieved initial success of PIT with elective PCI. Pain-to-needle time > 3h, ZWOLLE score and creatinine clearance were independent predictors of the need for rescue PCI

    Vascular complications in patients undergoing early percutaneous coronary intervention via the femoral artery after fibrinolysis with tenecteplase: registry of 199 patients

    BACKGROUND: Fibrinolysis is often used in the treatment of acute coronary syndromes with ST segment elevation (STEMI). Major cardiac outcomes were reduced with antiplatelet therapy intensification, but with increased risk of bleeding. Our objective was to assess the risk of vascular bleeding in patients undergoing early percutaneous coronary intervention after thrombolysis. METHODS: Between February 2010 and December 2011, five public emergency rooms in the city of São Paulo and the Emergency Health Care Service (Serviço de Atendimento Móvel de Urgência - SAMU) used tenecteplase (TNK) to treat patients with STEMI. Patients were referred to a single tertiary hospital and were submitted to early cardiac catheterization during hospitalization. All examinations were performed via the femoral artery and BARC criteria were used to classify bleeding. RESULTS: We evaluated 199 patients, of whom 193 had no bleeding of vascular origin (group 1) and 6 (3%) developed this complication (group 2). The median time between the administration of the fibrinolytic agent and catheterization was 24 hours in group 1 and 14.7 hours in group 2. According to BARC criteria, 1 patient had type 3a bleeding (hematoma in the inguinal region with a hemoglobin decrease of 3-5 g/dL), 2 patients had type 3b bleeding (1 not related to vascular access and 1 retroperitoneal hematoma with a hemoglobin decrease ≥ 5 g/dL) and the remaining patients had type 1 bleeding (small inguinal hematomas). Blood transfusions were required in 2 patients. None of the patients died due to vascular complications after the intervention. CONCLUSIONS: In our study, early catheterization via the femoral artery as part of a pharmaco-invasive strategy, using TNK as a fibrinolytic agent, had a low vascular bleeding rate, comparable to that of elective angioplasties.INTRODUÇÃO: A fibrinólise é frequentemente utilizada no tratamento das síndromes coronárias com supradesnivelamento do segmento ST (SCCSST). Desfechos cardíacos maiores foram reduzidos com a intensificação do tratamento antiplaquetário, porém com aumento do risco de sangramento. Nosso objetivo foi avaliar o risco de sangramentos de origem vascular em pacientes submetidos a intervenção coronária precoce pós-trombólise. MÉTODOS: Entre fevereiro de 2010 e dezembro de 2011, 5 prontos-socorros municipais da cidade de São Paulo e o Serviço de Atendimento Móvel de Urgência (SAMU) utilizaram tenecteplase (TNK) para tratamento de pacientes com SCCSST. Os pacientes foram encaminhados a um único hospital terciário e submetidos a cateterismo cardíaco precoce durante a internação. Todos os exames foram realizados por via femoral e os critérios do BARC foram utilizados para a classificação dos sangramentos. RESULTADOS: Foram avaliados 199 pacientes, dos quais 193 não apresentaram sangramento de origem vascular (grupo 1) e 6 (3%) evoluíram com essa complicação (grupo 2). A mediana de tempo entre a administração do fibrinolítico e o cateterismo foi de 24 horas no grupo 1 e de 14,7 horas no grupo 2. Segundo os critérios do BARC, 1 paciente apresentou sangramento do tipo 3a (hematoma em região inguinal com queda de hemoglobina de 3-5 g/dl), 2 pacientes apresentaram sangramento do tipo 3b (1 não relacionado ao acesso vascular e 1 hematoma de retroperitônio, com queda de hemoglobina ≥ 5 g/dl), e os demais apresentaram sangramentos do tipo 1 (pequenos hematomas em região inguinal). Nesse grupo foram necessárias duas hemotransfusões. Nenhum paciente teve óbito relacionado à complicação vascular pós-intervenção. CONCLUSÕES: Em nosso estudo, a cateterização precoce via femoral como parte de uma estratégia fármaco-invasiva, utilizando TNK como fibrinolítico, apresentou baixa taxa de sangramentos de origem vascular, comparável à das angioplastias eletivas.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Hemodinâmica e Cardiologia IntervencionistaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MiocardiopatiasUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaServiço de Atendimento Móvel de UrgênciaUNIFESP, EPM, Depto. de Hemodinâmica e Cardiologia IntervencionistaUNIFESP, EPM, Depto. de MiocardiopatiasUNIFESP, EPMSciEL

    BACKGROUND: Intravascular ultrasound (IVUS) provides a sensitive and reproducible measurement of coronary artery dimensions, atherosclerotic plaque, and arterial lumen. Advances in IVUS technology now allow the characterization of the composition and morphology of atherosclerotic plaques. Although previous studies have reported data using IVUS radiofrequency analysis, the use of a new modality (iMap®, Boston Scientific, Santa Clara, USA) of atherosclerotic plaque characterization is very little known. Our objective is to analyze the morphological, phenotypic and tissue characteristics of culprit and non-culprit atherosclerotic plaques determined by angiography in patients undergoing coronary angiography due to acute myocardial infarction (AMI). METHODS: Prospective, cross-sectional, single center study (Hospital São Paulo - Escola Paulista de Medicina - Universidade Federal de São Paulo (UNIFESP)/UNIFESP, São Paulo, SP, Brazil). Fifty patients will be selected for ultrasound analysis according to the following inclusion criteria: age < 75 years, non-ST-segment elevation AMI or recent ST-segment elevation AMI, with or without previous fribrinolytic agents. CONCLUSIONS: The present study is aimed at obtaining morphological, phenotypic and tissue characteristics of the atherosclerotic plate using an imaging modality not extensively evaluated in patients with AMI.INTRODUÇÃO: O ultrassom intracoronário (USIC) é um método capaz de fornecer medida sensível e reprodutível das dimensões da artéria coronária, da placa aterosclerótica e do lúmen arterial. Avanços em sua tecnologia permitem agora a caracterização da composição e da morfologia das placas ateroscleróticas. Embora estudos prévios tenham reportado dados utilizando USIC com análise de radiofrequência, o uso de uma nova modalidade (iMap®, Boston Scientific, Santa Clara, Estados Unidos) de caracterização da placa aterosclerótica é muito pouco conhecida. Nosso objetivo será analisar as características morfológicas, teciduais e fenotípicas das placas ateroscleróticas consideradas angiograficamente culpadas e não-culpadas em pacientes submetidos a angiografia coronária decorrente de infarto agudo do miocárdio (IAM). MÉTODOS: Estudo prospectivo, transversal, em único centro (Hospital São Paulo - Escola Paulista de Medicina - Universidade Federal de São Paulo (UNIFESP)/UNIFESP, São Paulo, SP, Brasil). Serão selecionados 50 pacientes para análise ultrassonográfica, de acordo com os seguintes critérios de inclusão: idade < 75 anos, IAM sem supradesnivelamento do segmento ST ou IAM com supradesnivelamento do segmento ST recente, com ou sem uso de fibrinolítico prévio. CONCLUSÕES: O presente estudo objetivará a caracterização morfológica, tecidual e fenotípica da placa aterosclerótica utilizando uma nova modalidade de imagem ainda pouco estudada em pacientes com IAM.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Setor de Hemodinâmica e Cardiologia IntervencionistaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaBoston Scientific Setor de Imagem em Cardiologia IntervencionistaHospital Israelita Albert EinsteinUNIFESP, EPM, Setor de Hemodinâmica e Cardiologia IntervencionistaUNIFESP, EPMSciEL
