ABSTRACT
Background: Primary percutaneous coronary intervention is the preferred treatment in ST-elevation myocardial infarction. At night period, the delay until performing primary percutaneous coronary intervention may be determinant to prognosis worsening. Objective: To analyze the results of primary percutaneous coronary intervention performed at day and night periods. Methods: Cohort study that included patients admitted with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention from December 2013 until December 2016 in a ST-elevation myocardial infarction reference hospital of a metropolitan region in Brazil, followed from admission to hospital discharge or death, compared according to time of primary percutaneous coronary intervention (night or day). Statistical analysis comprehended the Chi-square test, the Fisher test, the Student's t-test and the analysis of variance, with significance level of 5%. Results: 446 patients were submitted to primary percutaneous coronary intervention, 159 (35.6%) at night time and 287 (64.4%) at day time. No differences were found between the two groups concerning clinical baseline characteristics. Door-to-balloon time (101 ± 81 minutes vs. 99 ± 78 minutes; p = 0,59) and onset-to-ballon time (294 ± 158 minutes vs. 278 ± 174 minutes; p = 0,32) did not differ between the groups. The incidence of combined major adverse cardiac events (15.1% vs. 14.3%; p = 0,58) and in-hospital mortality (9.4% vs. 8.0%; p = 0,61) were similar between the groups, as well as length of hospital stay (6.0 ± 4 days vs. 4.9 ± 4 days; p = 0,91). Conclusion: Primary percutaneous coronary intervention at night time showed similar results as the procedure performed at day time, without significant increase of in-hospital adverse events, length of stay or mortality

Introdução: O uso da via radial em intervenções cardíacas associa-se à redução das complicações vasculares, porém requer maior curva de aprendizado e pode aumentar a exposição do paciente e da equipe à radiação. Este estudo teve como objetivo avaliar o tempo de fluoroscopia, como variável substituta para a exposição à radiação, durante cateterismo cardíaco diagnóstico pelas vias radial e femoral. Métodos: Estudo retrospectivo observacional que incluiu pacientes submetidos ao cateterismo cardíaco entre julho de 2013 e outubro de 2014. Foram comparados os grupos radial e femoral quanto ao tempo total do procedimento, tempo de fluoroscopia, relação tempo de fluoroscopia/procedimento e complicações vasculares. Resultados: Foram incluídos 1.915 procedimentos, sendo 11,2% realizados por via radial e 88,8% realizados por via femoral. Observou-se predomínio do sexo masculino no grupo radial (80% vs. 54,1%; p < 0,01), mas a média de idades (61,6 ± 9,7 vs. 62,4 ± 11,6; p = 0,13), o tempo do procedimento (8,7 ± 3,8 vs. 8,1 ± 4,1 minutos; p = 0,91), o tempo de fluoroscopia (4,8 ± 2,7 vs. 4,1 ± 2,6 minutos; p = 0,89), a relação tempo de fluoroscopia/procedimento (0,56 ± 0,24 vs. 0,49 ± 0,32; p = 0,89) e as complicações maiores (0,0% vs. 0,3%; p = 0,55) foram semelhantes entre os grupos. Conclusões: A utilização da via radial para procedimentos diagnósticos por operadores experientes pode ser feita com um tempo de procedimento aceitável, sem aumentar a exposição radiológica do paciente e da equipe, e com baixo número de complicações...
Background: The use of radial access in cardiac interventions is associated with reduced vascular complications, however it demands a longer learning curve and may increase fluoroscopy time. This study aimed to evaluate the fluoroscopy time as a surrogate marker of radiation exposure, during diagnostic cardiac catheterization by radial and femoral routes. Methods: Retrospective observational study including patients who underwent cardiac catheterization from July 2013 to October 2014. Radial and femoral groups were compared for total procedural time, fluoroscopy time, fluoroscopy to procedural time ratio and vascular complications. Results: The study included 1,915 procedures, 11.2% of which performed by radial approach and 88.8%, by femoral approach. A male prevalence was found in the radial group (80% vs. 54.1%, p < 0.01), but age (61.6 ± 9.7 years vs. 62.4 ± 11.6 years, p = 0.13), total procedural time (8.7 ± 3.8 vs. 8.1 ± 4.1 minutes, p = 0.91), fluoroscopy time (4.8 ± 2.7 vs. 4.1 ± 2.6 minutes, p = 0.89), fluoroscopy/procedure time ratio (0.56 ± 0.24 vs. 0.49 ± 0.32, p = 0.89), and major complications (0.0% vs. 0.3%, p = 0.55) were similar between groups. Conclusions: The use of the transradial approach for diagnostic procedures by experienced operating physicians may be used with an acceptable total procedural time without increasing the radiation exposure of the patient and staff, and with a low incidence of complications...

Introdução: O tratamento do infarto agudo do miocárdio com supradesnivelamento de ST tem a intervenção coronária percutânea primária como método preferencial de reperfusão. Este estudo teve como objetivo avaliar a evolução hospitalar de pacientes com infarto agudo do miocárdio com supradesnivelamento de ST, conforme o tempo total de isquemia, até a realização de intervenção coronária percutânea primária. Métodos: Registro unicêntrico, de pacientes admitidos com infarto agudo do miocárdio com supradesnivelamento de ST submetidos à intervenção coronária percutânea primária entre março de 2012 e fevereiro de 2014, acompanhados da admissão até a alta hospitalar e comparados conforme o tempo total de isquemia (Grupo 1: tempo dor-balão < 6 horas; Grupo 2: tempo dor-balão ≥ 6 e < 12 horas). Resultados: Foram submetidos à intervenção coronária percutânea primária 279 pacientes, sendo 118 do Grupo 1 (42,3%) e 161 do Grupo 2 (57,7%). O Grupo 2 apresentou idade mais avançada, maior prevalência de hipertensão arterial, menor proporção de tabagistas, maior número de pacientes em classe Killip-Kimball ≥ 2 e menor taxa de sucesso da intervenção coronária percutânea primária. As incidências de óbito ou infarto não fatal (11,0% vs. 18,6%; p = 0,08), óbito (8,5% vs. 16,8%; p = 0,04) e insuficiência renal aguda (7,6% vs. 19,9%; p < 0,01) foram maiores no Grupo 2. Conclusões: Pacientes com infarto agudo do miocárdio com supradesnivelamento de ST submetidos à intervenção coronária percutânea primária com tempo dor-balão ≥ 6 horas apresentaram maior complexidade clínica e pior evolução...
Background: Treatment of ST-elevation acute myocardial in -farction has primary percutaneous coronary intervention asthe preferred method of reperfusion. This study aimed to evaluate in-hospital outcomes of patients with ST-elevationacute myocardial infarction according to the total ischemic time until performing primary percutaneous coronary intervention. Methods: Single-center registry of patients admitted withST-elevation acute myocardial infarction undergoing primary percutaneous coronary intervention between March/2012 and February/2014, followed from admission to hospital discharge, and compared according to the total ischemic time (Group 1: symptom onset-to-balloon time < 6 hours; Group 2: symptom onset-to-balloon time ≥ 6 and < 12 hours). Results: Two hundred seventy nine patients underwent primarypercutaneous coronary intervention, 118 in Group 1 (42.3%) and 161 in Group 2 (57.7%). Group 2 was older, had higherprevalence of hypertension, fewer smokers, more patients inKillip-Kimball class ≥ 2 and lower primary percutaneous coronary intervention success rate. The incidences of death or non-fatal infarction (11.0% vs. 18.6%; p = 0.08), death (8.5%vs. 16.8%; p = 0.04) and acute renal failure (7.6% vs. 19.9%; p < 0.01) were greater in Group 2. Conclusions: Patients with ST-elevation acute myocardial infarction undergoing primarypercutaneous coronary intervention with symptom onset-toballoon time ≥ 6 hours presented higher clinical complexityand worse in-hospital outcomes when compared to patients treated earlier. Joint actions in different critical areas of patient care are essential to increase treatment efficacy and reduceadverse outcomes...

Relata-se o caso de paciente masculino, 55 anos, com infarto agudo do miocárdio com supradesnivelamento de ST em parede anterolateral, classe Killip III. Cinecoronariografia de urgência evidenciou tronco da coronária esquerda ocluído, com alta carga trombótica que se estendia para a raiz da aorta. Foi realizada intervenção coronariana percutânea primária com balão, associada à trombectomia aspirativa e trombólise química locorregional intracoronariana, sem necessidade de implante de stent. O paciente apresentou evolução clínica satisfatória e recebeu alta hospitalar após 15 dias.
Case report on a 55-year-old male with antero-lateral ST elevation myocardial infarction, Killip class III. Urgent coronary angiography revealed an occluded left main coronary artery and high thrombotic load that extended to the aortic root. Primary percutaneous coronary intervention was performed with a balloon catheter, associated with aspirative thrombectomy and intracoronary chemical thrombolysis, with no need for a stent implant. The patient presented good clinical progress and was discharged from the hospital fifteen days later.

OBJECTIVE: To assess whether coronary stenting in diabetic patients provides in-hospital results and clinical evolution similar to those in nondiabetic patients. METHODS: From July `97 to April '99 we performed coronary stent implantation in 386 patients with coronary heart disease, who were divided into two groups: diabetic patients and nondiabetic patients. The in-hospital results and the clinical evolution of each group were retrospectively analyzed. RESULTS: The nondiabetic group comprised 305 (79 percent) patients and the diabetic group 81 (21 percent) patients. Basic clinical and angiographic characteristics were similar. Angiographic success was in diabetics = 96.6 percent vs in nondiabetics = 97.9 percent (p=ns). Among the major complications in the in-hospital phase, the rate of myocardial infarction was higher in the diabetic group (7.4 percent vs 1.9 percent) (p=0.022). In the follow-up, a favorable and homogeneous evolution occurred in regard to asymptomatic patients, myocardial infarction, and death in the groups. A greater need for revascularization, however, existed in the diabetic patients (15 percent vs 2.4 percent, p<0.001). CONCLUSION: Coronary stenting in diabetic patients is an efficient procedure, with a high angiographic and clinical success rate similar to that in nondiabetic patients. Diabetic patients, however, had a higher incidence of in-hospital myocardial infarction and a greater need for additional myocardial revascularization

A estenose mitral ainda é uma das valvulopatias mais frequentes em nosso meio, sendo a principal cardiopatia reumática encontrada durante a gravidez. A valvuloplastia mitral com cateter balão (VMCB) é uma opção terapêutica alternativa de grande valia, ao tratamento cirúrgico, nos pacientes portadores de estenose mitral severa adequadamente selecionados. Neste trabalho procuramos demonstrar nossa experiência e resultados com a VMCB. Foram realizadas 305 valvoplastias percutâneas, entre o período de Janeiro/1988 a Setembro/1998; sendo que destas, 30(trinta) eram gestantes em classe funcional III e IV (NYHA) apesar da terapêutica medicamentosa. Foram avaliados a classe funcional, os resultados hemodinâmicos e ecocardiográficos, pré e pós procedimento e durante o follow up. O sucesso do procedimento, definido como área valvar mitral final >1.5cm² na ausência de complicações maiores (insuficiência mitral grave, necessidade de novo procedimento ou cirurgia, óbito), foi de 92 por cento. Houve uma melhora imediata da classe funcional, permanecendo a maioria dos pacientes em CF I e II. A avaliação ecocardiográfica no controle evolutivo demonstrou pequena diminuição da àrea valvar obtida após o porcedimento, mas ainda compatível com estenose mitral de grau leve. Estes resultados favoráveis imediatos e a longo prazo sugerem ser a VMCB o procedimento de escolha para o tratamento de pacientes portadores de estenose mitral adequadamente selecionados
