ABSTRACT

Resumo Fundamento A oclusão do apêndice atrial esquerdo (AAE) tem se mostrado uma alternativa à terapia de anticoagulação oral (ACO) para prevenção de acidente vascular cerebral (AVC) em pacientes com fibrilação atrial não valvar (FANV). Objetivos Descrever os primeiros resultados de uma experiência inicial multicêntrica no Brasil e investigar a viabilidade, a segurança e a eficácia da oclusão do AAE com o novo dispositivo LAmbre. Métodos Coletamos dados do procedimento e do acompanhamento de 51 pacientes consecutivos com FANV, restrições para ACO em longo prazo e com anatomia adequada, submetidos à oclusão do AAE com o dispositivo LAmbre em 18 centros no Brasil. Indicações para o procedimento foram: sangramento importante em pacientes recebendo ACO (47,1%), AVC ou trombo persistente no AAE apesar de ACO adequada (27.5%), sangramento e AVC (17.6%), outras contraindicações clínicas apara ACO (5,9%), e escolha do paciente devido à prática esportiva (1,9%). Resultados Foram estudados 25 homens (49%) e 26 mulheres (51%), com idade média de 76±7,7 anos, escore CHA2DS2-VASc médio de 4,6± 1,7 e escore HAS-BLED médio de 3.4± 1,1. A taxa de sucesso do procedimento foi de 100%. As complicações imediatas relacionadas ao procedimento foram derrame pericárdico em dois pacientes, e embolização do dispositivo em um caso. Não foram observados shunts residuais > 5mm. Shunts < 5mm foram detectados em quatro pacientes por Doppler colorido ao final do procedimento. Após um período médio de acompanhamento de 18 meses ± 12 meses, não foram observados óbito, AVC ou complicações maiores. Conclusão A oclusão do AAE com o dispositivo LAmbre foi segura e eficaz nesta pequena série de casos. Apesar desses resultados iniciais encorajadores, dado o pequeno número de casos, serão necessários mais estudos com um maior período de acompanhamento.


Abstract Background Left atrial appendage (LAA) closure has been an alternative to oral anticoagulation (OAC) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). Objectives To report the first results of an initial multicenter experience in Brazil and to investigate the feasibility, safety, and efficacy of LAA closure with the new LAmbre device. Methods We collected procedural and follow-up data of 51 consecutive patients with non-valvular atrial fibrillation, restrictions for long-term OAC and suitable anatomy that underwent LAA closure with the LAmbre device in 18 centers in Brazil. Procedural indications were significant bleeding under OAC (47.1%), stroke or persistent LAA thrombus despite OAC (27.5%), bleeding plus stroke (17.6%), other clinical contraindications for OAC (5.9%), and patient's choice due to sports practice (1.9%). Results Twenty-five men (49%) and 26 women (51%), with a mean age of 76±7.7 years, mean CHA2DS2-VASc score of 4.6± 1.7 and mean HAS-BLED score of 3.4± 1.1 were studied. Procedural success rate was 100%. Procedure-related immediate complications were pericardial effusion in two patients, and immediate device embolization in one case. No large residual shunts (> 5 mm) were observed, and small shunts (<5mm) were detected in four patients by color Doppler at the end of the procedure. After a mean follow-up of 18 ± 12 months, there were no deaths, strokes nor any other major complications. Conclusion LAA occlusion with the LAmbre device was safe and effective in this small case series. Despite these encouraging initial results, the small number of cases warrants further studies with longer-term follow-up.

ABSTRACT

Introdução: Apesar do advento dos stents farmacológicos (SF), diabéticos ainda experimentam risco aumentado de eventos cerebrovasculares e cardiovasculares maiores (ECCAM) após intervenção coronária percutânea (ICP). Nosso objetivo foi avaliar a incidência de ECCAM (óbito, acidente vascular cerebral, infarto agudo do miocárdio não fatal ou revascularização da lesão alvo) no seguimento de pelo menos 1 ano, além da capacidade de os escores SYNTAX e SYNTAX residual predizerem eventos. Métodos: Estudo unicêntrico, retrospectivo, de diabéticos com doença coronariana multiarterial, incluindo lesões de tronco de coronária esquerda (TCE), tratados com SF entre 2012 a 2014. Resultados: Foram incluídos 158 pacientes, com média de idades de 65,1 ± 9,1 anos. Em 44,2% dos casos, havia lesão proximal da artéria descendente anterior e 9% apresentavam lesão de TCE. A maioria dos procedimentos foi realizada com SF de segunda geração (91,1%). A média de seguimento foi de 1.054 ± 725 dias, e o ECCAM ocorreu em 17,4% dos pacientes. Entre aqueles com escore SYNTAX baixo (< 23), 10,2% apresentaram ECCAM, enquanto que entre os que foram categorizados como com SYNTAX moderado/alto (≥ 23), a incidência foi de 33,3% (p = 0,003). Dos pacientes com escore SYNTAX residual zero (revascularização completa), 7,5% evoluíram com ECCAM, comparados com 22,0% com revascularização incompleta (p = 0,01). Conclusões: O presente estudo aponta para a factibilidade e a segurança da realização de ICP em diabéticos multiarteriais, especialmente entre aqueles com baixa complexidade angiográfica. A revascularização incompleta foi preditora da maior ocorrência de ECCAM no seguimento de médio/longo prazo


Background: Despite the advent of drug-eluting stents (DES), diabetic patients still have increased risk of major adverse cardiovascular and cerebrovascular (MACCE) after percutaneous coronary intervention (PCI). Our aim was to evaluate the incidence of MACCE (death, stroke, non-fatal acute myocardial infarction, or target-lesion revascularization) during a follow-up of at least 1 year, in addition to the ability of the SYNTAX and residual SYNTAX scores to predict events. Methods: Single-center, retrospective study of diabetic patients with multivessel coronary disease, including left main coronary artery (LMCA) lesions treated with DES between 2012 and 2014. Results: A total of 158 patients were included, with a mean age of 65.1 ± 9.1 years. In 44.2% of the cases, there was a proximal lesion in the left anterior descending artery and 9% had a lesion in the LMCA. Most procedures were performed with second-generation DES (91.1%). Mean follow-up was 1,054 ± 725 days, and MACCE occurred in 17.4% of the patients. Among those with a low SYNTAX score (< 23), 10.2% had MACCE, while among those classified as having a moderate/high SYNTAX score (≥ 23), the incidence was 33.3% (p = 0.003). Of the patients with zero residual SYNTAX score (complete revascularization), 7.5% progressed with MACCE, compared with 22.0% with incomplete revascularization (p = 0.01). Conclusions: The present study points to the feasibility and safety of performing PCI in multivessel diabetic patients, especially among those with low angiographic complexity. Incomplete revascularization was a predictor of a higher occurrence of MACCE in the medium/long-term follow-up

ABSTRACT

PURPOSE: To evaluate the effect of parecoxib (an NSAID) on renal function by measuring plasma NGAL (serum neutrophil gelatinase-associated lipocalin) levels in an induced-ischemia rat model. METHODS: Forty male Wistar rats were randomly assigned to one of four groups: Ischemia (I), Ischemia/parecoxib (IP), No-ischemia (NI), and No-ischemia/parecoxib (NIP). Body weight, mean arterial pressure, heart rate, body temperature, NGAL levels, and renal histology were compared across groups. RESULTS: The Ischemia (I) group, which did not receive parecoxib, showed the highest NGAL levels (p=0.001), while the IP group, which received the medication, had NGAL levels similar to those of the non-ischemic (NI and NIP) groups. CONCLUSION: Parecoxib resulted in renal protection in this experimental model. .
