RESUMO
Advocacy is a core mission of the Society for Cardiovascular Angiography & Interventions (SCAI). SCAI advocates on behalf of interventional cardiologists and our patients. This document provides foundational information and a toolkit for grassroots advocacy by interventional cardiologists. The first half of the document summarizes how health care laws are made, how medical devices are approved, and how procedure reimbursement is determined. The second half of the document is a playbook of advocacy strategies: legislative advocacy, judicial advocacy, advocacy with regulators and payors, advocacy in the media, and participation in SCAI advocacy initiatives, such as the Government Relations Committee and SCAI Political Action Committee. Equipped with this toolbox, interventional cardiologists must increase our advocacy activities with government, payors, and industry.
RESUMO
Evidence-based recommendations for clinical practice are intended to help health care providers and patients make decisions, minimize inappropriate practice variation, promote effective resource use, improve clinical outcomes, and direct future research. SCAI has been engaged in the creation and dissemination of clinical guidance documents since the 1990s. These documents are a cornerstone of the Society's education, advocacy, and quality improvement initiatives. The Publications Committee is charged with the oversight of SCAI's clinical documents program and has published the first iteration of this manual of standard operating procedures in 2019 to ensure consistency, methodological rigor, and transparency in the development and endorsement of the Society's documents. The manual has been updated based on feedback from the implementation of the original version to add specificity and expand the breadth of available document formats. The manual is intended for reference by the Publications Committee, document writing groups, external collaborators, SCAI representatives, peer reviewers, and anyone seeking information about the SCAI documents program.
RESUMO
FUNDAMENTO: O bloqueio completo do ramo esquerdo esforço-induzido (BCRE E-I) é um achado infrequente ao teste de exercício e sua prevalência e significado prognóstico não são claros. OBJETIVO: Avaliar de forma longitudinal a prevalência e o significado prognóstico do BCRE E-I em homens americanos veteranos de guerra. MÉTODOS: Avaliamos 9.623 pacientes que realizaram ergometria em esteira (TE) entre 1987 e 2007. Os desfechos foram comparados entre aqueles com TE NL, os com BCRE E-I e os que apresentaram Dep ST anormal. A mortalidade e a causa das mortes foram identificadas de forma cega para os resultados do TE. RESULTADOS: Nesta coorte prospectiva, 6922 indivíduos apresentaram TE NL (57,2 ± 11,4 anos), 1.739 apresentaram Dep ST anormal (62,7 ± 9,8 anos) e 38 casos de BCRE E-I foram identificados (65,2 ± 11,9 anos). A prevalência do BCRE E-I foi 0,38 por cento. Após 8,8 anos, ocorreram 1.699 mortes por todas as causas e 610 mortes cardiovasculares (CV). Doença arterial coronária e insuficiência cardíaca foram mais prevalentes nos pacientes com BCRE E-I. Pacientes com BCRE E-I tiveram razão de azar de 2,37 (p = 0,002) para mortalidade por todas as causas, mas a mesma não foi significativa quando ajustada para idade ou quando a mortalidade cardiovascular foi o desfecho avaliado. CONCLUSÃO: BCRE E-I é um achado raro. Indivíduos com BCRE E-I apresentam maior mortalidade por todas as causas quando comparados aqueles com TE NL. No entanto, tal fato é explicado por esses pacientes serem significativamente mais velhos e por apresentarem mais enfermidades cardiovasculares associadas.
BACKGROUND: Exercise-induced left bundle branch block (EI-LBBB) is an infrequent finding. Its prevalence and prognostic significance are not clear. OBJECTIVE: To evaluate, in a longitudinal study, the prevalence and prognostic significance of EI-LBBB in American war veterans. METHODS: We evaluated 9,623 patients submitted to an exercise test (ET) in treadmill between 1987 and 2007. The outcomes were compared between those with normal TE, the ones with EI-LBBB and the ones with down-sloping ST-segment. Mortality and causes of death were identified while blinded to the ET results. RESULTS: In this prospective cohort, 6,922 individuals had normal ET results (57.2 ± 11.4 years), 1,739 had abnormal ST-segment depression (62.7 ± 9.8 years), and 38 had EI-LBBB (65.2 ± 11.9 years). The prevalence of EI-LBBB was 0.38 percent. After 8.8 years, there were 1,699 deaths due to all-cause mortality and 610 cardiovascular (CV) deaths; coronary artery disease and heart failure were more prevalent in patients with EI-LBBB. Patients with EI-BCRE had a hazard ratio of 2.37 (p = 0.002) for all-cause mortality, but it was not significant when adjusted for age or when the CV death was the assessed outcome. CONCLUSION: EI-LBBB is a rare clinical finding. Individuals with BCRE-EI have higher all-cause mortality when compared to those with normal ET results. However, this fact is explained by the fact that these patients are significantly older and have more associated cardiovascular diseases.
FUNDAMENTO: El bloqueo completo de rama izquierda esfuerzo-inducido (BCRI E-I) es un hallazgo infrecuente en el test de ejercicio y su prevalencia y significado pronóstico no son claros. OBJETIVO: Evaluar de forma longitudinal la prevalencia y el significado pronóstico del BCRI E-I en los hombres norteamericanos veteranos de guerra. MÉTODOS: Evaluamos 9.623 pacientes que realizaron ergometría en cinta (TE) entre 1987 y 2007. Los resultados fueron comparados entre aquellos con TE normal (TE NL), los con BCRI E-I y los que presentaron infradesnivel del segmento ST (Dep ST) anormal. La mortalidad y la causa de las muertes fueron identificadas de forma ciega para los resultados del TE. RESULTADOS: En esta cohorte prospectiva y después de las exclusiones, 6.922 individuos presentaron EC NL (57,2 ± 11,4 años), 1739 tuvieron Dep ST anormal (62,7 ± 9,8 años), y 32 casos de BCRI E-I fueron identificados (65,2 ± 11,9 años). La prevalencia del BCRI E-I fue del 0,38 por ciento. Después de 8,8 años, ocurrieron 1699 muertes por todas las causas y 610 muertes cardiovasculares (CV). La enfermedad arterial coronaria y la insuficiencia cardíaca fueron las más prevalentes en los pacientes con BCRI E-I. Los pacientes con BCRI E-I presentaron azar de 2,37 (p = 0,002) para la mortalidad por todas las causas, pero ella no fue significativa cuando se ajustó para la edad o cuando la mortalidad cardiovascular fue el desenlace evaluado. CONCLUSIÓN: BCRI E-I es un hallazgo raro. Los individuos con BCRI E-I presentan una mayor mortalidad por todas las causas cuando se les compara con los de EC NL. Sin embargo, ese hecho se explica porque esos pacientes son significativamente más viejos y por presentar más enfermedades cardiovasculares asociadas.
