          Abstract

          SUMMARY BACKGROUND The Medical Control Program for Occupational Health establishes the required supplementary exams, according to the activity exercised by the worker and its inherent risks. The Regulatory Norm No. 35, recently deployed, stipulates that at-height workers must undergo electrocardiogram exams as an additional routine examination. OBJECTIVE To evaluate the electrocardiographic standard in at-height. METHODOLOGY A cross-sectional study, developed from May 2014 to January 2015 with male at-height workers. Anthropometric and clinical data were collected after the electrocardiogram (ECG). The workers included in the program were evaluated by an occupational medicine service of Serra Gaúcha, responsible for medical assessment and occupational tests. All workers were assessed by the researcher. RESULTS A total of 561 at-height workers participated in the study. The average age was 35.9 ± 12.2 years. A total of 176 (31%) presented electrocardiographic changes in the analysis of the resting ECG. Regarding the amendments in the resting ECG, 15.7% were attributed to changes in ventricular repolarization, 8% as blocks conductions, and 5.8% as left ventricular overload. Demographic variables were not associated with changes in the electrocardiographic tracing CONCLUSION This study demonstrated the electrocardiographic alterations and the profile of at-height workers. These findings can help determine prevention strategies and provide warnings of possible future harms to the health of these workers.

          RESUMO FUNDAMENTO O Programa de Controle Médico e Saúde Ocupacional estabelece a realização de exames complementares de acordo com a atividade exercida pelo trabalhador e os riscos a ela inerentes. A Norma Regulamentadora n0 35, implantada recentemente, estabelece que trabalhadores que exercem funções em altura realizem o eletrocardiograma como um exame complementar de rotina. OBJETIVO Avaliar o padrão eletrocardiográfico dos trabalhadores em altura por meio da realização do ECG de repouso. MÉTODOS Estudo transversal, desenvolvido de maio de 2014 a janeiro de 2015 com trabalhadores masculinos que exercem funções em altura. Foram coletados dados clínicos e demográficos e, após, realizado o eletrocardiograma (ECG). Os trabalhadores incluídos eram vinculados a um serviço de medicina do trabalho da Serra Gaúcha, destinado à realização de avaliação médica e exames ocupacionais. Todos foram avaliados pela pesquisadora. RESULTADOS Participaram 561 trabalhadores em altura. A média de idade foi de 35,9±12,2 anos, e 176 (31%) apresentaram alterações eletrocardiográficas na análise dos ECG de repouso. Das alterações do ECG de repouso, 15,7% foram atribuídas a alterações da repolarização ventricular; 8% como bloqueios de condução e 5,8% como sobrecarga de ventrículo esquerdo. As variáveis demográficas não estavam associadas com alterações no traçado eletrocardiográfico. CONCLUSÃO Este estudo verificou que a prevalência de sobrecarga de ventrículo esquerdo e alteração da repolarização ventricular, nos trabalhadores em altura, é maior quando comparada a estudos populacionais brasileiros. A associação de fatores de risco e alterações eletrocardiográficas em indivíduos difere de populações específicas.

            The epidemiology of cardiovascular disease in the UK 2014

            Cardiovascular disease (CVD) presents a significant burden to the UK. This review presents data from nationally representative datasets to provide up-to-date statistics on mortality, prevalence, treatment and costs. Data focus on CVD as a whole, coronary heart disease (International Classification of Diseases (ICD):I20–25) and cerebrovascular disease (ICD:I60–69); however, where available, other cardiovascular conditions are also presented. In 2012, CVD was the most common cause of death in the UK for women (28% of all female deaths), but not for men, where cancer is now the most common cause of death (32% of all male deaths). Mortality from CVD varies widely throughout the UK, with the highest age-standardised CVD death rates in Scotland (347/100 000) and the North of England (320/100 000 in the North West). Prevalence of coronary heart disease is also highest in the North of England (4.5% in the North East) and Scotland (4.3%). Overall, around three times as many men have had a myocardial infarction compared with women. Treatment for CVD is increasing over time, with prescriptions and operations for CVD having substantially increased over the last two decades. The National Health Service in England spent around £6.8 billion on CVD in 2012/2013, the majority of which came from spending on secondary care. Despite significant declines in mortality in the UK, CVD remains a considerable burden, both in terms of health and costs. Both primary and secondary prevention measures are necessary to reduce both the burden of CVD and inequalities in CVD mortality and prevalence.
