Background: Clinical in-stent restenosis (CISR) is the main limitation of coronary angioplasty with stent implantation. Objective: Describe the clinical and angiographic characteristics of CISR and the outcomes over a minimum follow-up of 12 months after its diagnosis and treatment. Methods: We 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. Results: Mean 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. Conclusion: Patients with CISR present in most cases with ACS and with a high frequency of adverse events during a medium-term follow-up.

Identification of high-risk patients undergoing primary angioplasty (PCI) is essential.Identify factors related to the causes of death in PCI patients.This work consisted of a multicenter case-control study using a Brazilian registry of cardiovascular interventions as the data source. The association between each variable and death was assessed using a binary logistic regression model, p0.05 was considered significant.A total of 26,990 records were analyzed, of which 18,834 (69.8%) were male patients, with a median age of 61 (±17) years. In the multivariate analysis, the main variables related to the causes of death with their respective odds ratios and 95%confidence intervals (CI) were advanced age, 70-79 years (2.46; 1.64-3.79) and ≥ 80 years (3.69; 2.38-5.81), p0.001; the classification of Killip II (2.71; 1.92-3.83), Killip III (8.14; 5.67-11.64), and Killip IV (19.83; 14.85-26.69), p0.001; accentuated global dysfunction (3.63; 2,39-5.68), p0.001; and the occurrence of infarction after intervention (5.01; 2.57-9.46), p0.001. The main protective factor was the post-intervention thrombolysis in myocardial infarction (TIMI) III flow (0.18; 0.13-0.24), p0.001, followed by TIMI II (0.59; 0.41 -0.86), p=0.005, and male (0.79; 0.64-0.98), p = 0.032; dyslipidemia (0.69; 0.59-0.85), p0.001; and number of lesions treated (0.86; 0.9-0.94), p0.001.The predictors of mortality in patients undergoing PCI were Killip's classification, reinfarction, advanced age, severe left ventricular dysfunction, female gender, and post-intervention TIMI 0 / I flow.A estratificação do risco de morte dos pacientes no contexto da angioplastia primária (ATC) é fundamental.Identificar os fatores relacionados ao desfecho morte em pacientes submetidos a ATC.Estudo de caso-controle, utilizando como fonte de dados um registro brasileiro. A associação entre cada variável e o desfecho óbito foi avaliada via modelo de regressão logística binária. Consideramos significativo p0,05.Foram analisados 26.990 registros, sendo 18.834 (69,8%) do sexo masculino, com idade mediana de 61 (17) anos. Na análise multivariada, as principais variáveis relacionadas ao desfecho óbito com seus respectivos odds ratio e intervalos de confiança (IC) com nível de significância de 95% foram a idade avançada 70 - 79 anos (2,46; 1,64 - 3,79) e ≥ 80 anos (3,68; 2,38 - 5,81), p0,001, classificação de Killip II (2,71; 1,92 - 3,83), Killip III (8,14; 5,67 - 11,64), Killip IV (19,83; 14,85 - 26,69), p0,001, disfunção global acentuada do ventrículo esquerdo (VE) (3,63; 2,39 - 5,68), p0,001 e ocorrência de infarto após a intervenção (5,01; 2,57- 9,46), p0,001. O principal fator protetor foi o fluxo TIMI III pós-intervenção (0,18; 0,13 - 0,24), p0,001, seguido do TIMI II (0,59; 0,41 - 0,86), p=0,005, sexo masculino (0,79; 0,64 - 0,98), p= 0,032, dislipidemia (0,69; 0,59 - 0,85), p0,001 e número de lesões tratadas (0,86; 0,9 - 0,94), p0,001.Os preditores de mortalidade nos pacientes submetidos a ATC foram: classificação de Killip, reinfarto, idade, disfunção global acentuada do VE, sexo feminino e fluxo TIMI 0/I pós-intervenção.

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. Conclusion: Patients with CISR present in most cases with ACS and with a high frequency of adverse events during a medium-term follow-up. Fundamento: A Reestenose Intrastent Clínica (RISC) é a principal limitação da angioplastia coronariana com implante de stent. Objetivo: Descrever as características clínicas e angiográficas da RISC e os desfechos em seguimento de pelo menos doze meses após seu diagnóstico e tratamento. Métodos: Em 110 pacientes consecutivos com RISC, analisaram-se a apresentação clínica, as características angiográficas, o tratamento e os desfechos primário combinado (morte cardiovascular, Infarto Agudo Miocárdio não fatal [IAM]) e secundário combinado (angina instável com internação, revascularização de vaso alvo e lesão alvo) em seguimento mínimo de um ano. Resultados: A média de idade da amostra foi de 61 ± 11 anos (68,2% do sexo masculino). A apresentação clínica foi como Síndrome Coronariana Aguda (SCA) em 62,7%, com RIS proliferativa em 34,5% dos casos. O tratamento realizado foi o implante de Stent Farmacológico (SF) em 36,4%; de Stent Não Farmacológico (SNF) em 23,6%; cirurgia de revascularização em 18,2%; angioplastia por balão em 15,5%; e tratamento clínico em 6,4%. Com seguimento mediano de 19,7 meses, o desfecho primário ocorreu em 18 pacientes, com seis (5,5%) óbitos e 13 (11,8%) IAM, e o secundário em 24 pacientes. Foram preditores de desfecho primário a RISC em SF (HR = 4,36; [1,44 - 12,85], p = 0,009) e o tratamento clínico da RISC (HR = 10,66, [2,53 - 44,87], p = 0,001). O tratamento da RISC com SNF (HR = 4,08 [1,75 - 9,48], p = 0,001) e tratamento clínico (HR = 6,29 [1,35 - 29,38], p = 0,019) foram preditores do desfecho secundário. Conclusão: A RISC se apresenta como SCA na maioria dos casos e os pacientes apresentam elevada frequência de eventos adversos durante o seguimento de médio prazo.

INTRODUÇÃO: O infarto agudo do miocárdio (IAM) permanece com elevados índices de morbidade e mortalidade e representa problema de saúde pública. Analisamos os resultados e os preditores de risco de eventos adversos hospitalares em pacientes submetidos a intervenção coronária percutânea (ICP) eletiva pós-fibrinólise. MÉTODOS: Foram selecionados 303 pacientes com diagnóstico de IAM submetidos a reperfusão farmacológica e transferidos para um centro terciário para realização de ICP eletiva. RESULTADOS: A população era predominantemente masculina (76,6%), com média de idade de 59,4 + 11,1 anos, 18,1% eram diabéticos e 86,8% estavam em Killip I. Estreptoquinase foi empregada em 91,7%, o tempo médio de realização da ICP eletiva foi de 5,6 + 3,7 dias após a fibrinólise e o fluxo TIMI 3 (74,2%) foi o mais prevalente. Os stents foram implantados em 97,7% dos pacientes e o sucesso angiográfico foi de 95,3%. Mortalidade ocorreu em 3,3% dos pacientes; reinfarto, em 3,6%; revascularização da lesão-alvo, em 1,3%; e sangramentos maiores, em 2%. A análise multivariada apontou sexo feminino, idade > 65 anos, fluxo TIMI 1, presença de trombos no vaso tratado, Killip > I e disfunção grave do ventrículo esquerdo como preditores independentes de eventos adversos hospitalares. CONCLUSÕES: A estratégia de reperfusão farmacológica seguida de transferência para realização de ICP apresenta baixas taxas de eventos adversos hospitalares e é alternativa interessante à ICP primária no cenário nacional. Necessita, no entanto, políticas públicas para aperfeiçoar a logística de manuseio desses pacientes e dispô-la de maneira eficiente a todos os hospitais de baixa e média complexidades nacionais. BACLGROUND: Acute myocardial infarction (AMI) has a high morbidity and mortality and represents a public health problem. We analyzed the results and predictors of in-hospital adverse events in patients undergoing elective percutaneous coronary intervention (PCI) after fibrinolysis. METHODS: Three hundred and three patients with diagnosis of AMI undergoing pharmacological reperfusion and transferred to a tertiary center for elective PCI were selected. RESULTS: The population included mostly men (76.6%), with mean age of 59.4 + 11.1 years, 18.1% were diabetic and 86.8% were in Killip class I. Streptokinase was used in 91.7%, the mean time to perform elective PCI was 5.6 + 3.7 days after fibrinolysis and TIMI 3 flow was achieved in 74.2% of the patients. Stents were implanted in 97.7% and angiographic success was obtained in 95.3% of the cases. Mortality was observed in 3.3%, reinfarction in 3.6%, target lesion revascularization in 1.3%, and major bleedings in 2% of the patients. Multivariate analysis indicated female gender, age > 65 years, TIMI 1 flow, thrombus in the treated vessel, Killip > I and severe left ventricular dysfunction were independent predictors of in-hospital adverse events. CONCLUSIONS: The pharmacological reperfusion strategy followed by transfer to perform elective PCI had low in-hospital adverse event rates and is an interesting alternative to primary PCI in Brazil. However, public policies are required to improve the logistics to better handle these patients and have them available to all low and medium complexity national hospitals.

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. Scientific reports on mesenteric arterial ischemia suggest that the disease is not thoroughly understood, is poorly diagnosed and rarely treated, despite its high lethality. The prognosis of mesenteric ischemia depends on a fast restoration of blood flow, which may be achieved by clinical, surgical and endovascular management or by a combination of all them. This article reviews the diagnostic evidence of mesenteric ischemia and the available therapeutic options including percutaneous intervention as an alternative method to surgery, which is associated to significant mortality and morbidity rates.
