Abstract Background Nothing is known about ischemic heart disease (IHD) in the Germans who emigrated to Brazil during the last century. Objective We sought to compare age at diagnosis and IHD manifestations between German immigrants and their first-generation descendants in the region of Blumenau, Brazil. Methods We reviewed medical records of hospitals in Blumenau. Comparison of the groups in the evaluation times was made by analysis of variance (ANOVA) with repeated measures, and comparison of two factors was made by two-way ANOVA. The level of significance was set at p <0.05. Results Study population comprised 68 patients who were born in Germany (group G) and 99 descendants (group D). Twenty-nine patients of group D had two German parents and 70 had one. Mean age at diagnosis was 66.8 ± 10.6 years, with a significant difference between the groups, four years higher in Group G than group D (69.0 ± 8.8 vs 65.4 ± 11.5 years old) (p = 0.025). There was no significant difference in risk factors or coronary angiography data between the groups. HDL cholesterol levels were significantly higher in group G than in group D (48.4 ± 11.1 mg/dL vs 43.3 ± 11.2 mg/dL, p = 0.005). Conclusion At the time of first IHD diagnosis, mean age of the group G was significantly higher than group D, with no differences between groups in sex, risk factors, LDL levels, or clinical and angiographic manifestations. An earlier manifestation of the disease could be part of lifestyle changes in descendants, in this population that mantained eating habits characterized by high saturated fat consumption.

Resumo Fundamento A redução da mortalidade e das sequelas de uma vítima de parada cardíaca depende de um atendimento eficaz, rápido e iniciado o mais precocemente possível. O suporte básico de vida (SBV) compreende uma série de etapas que podem ser iniciadas fora do ambiente hospitalar, e ensinadas para qualquer pessoa em cursos específicos. Porém, é importante que o socorrista retenha o conhecimento e as habilidades, pois nunca se sabe quando será necessário realizar uma ressuscitação cardiopulmonar (RCP). Entretanto, estudos mostram que existe uma perda das habilidades em executar uma RCP já com 30 dias após o treinamento, com variações segundo algumas características das pessoas e da atividade profissional. Objetivo Avaliar se os estudantes de medicina são capazes de reter as habilidades por mais de seis meses. Métodos Estudo prospectivo, caso controle, observacional. Estudantes de medicina realizaram um curso sobre morte súbita e parada cardíaca de 40 horas. A avaliação das habilidades foi realizada imediatamente após o curso e seis meses depois. Foram comparadas as notas individuais entre dois momentos, foi avaliada a porcentagem de acerto em cada etapa e uma análise global do atendimento foi classificado como ótimo, bom e ruim. Os avaliadores e critérios foram os mesmos nos dois momentos. Os dados foram analisados pelos teste-t pareado e teste de McNemar, onde para um nível de confiança de 95% o critério para significância foi p < 0,05. Resultados Cinquenta estudantes (27 do sexo feminino) do primeiro ano, com idade entre 18 e 24 anos (média 21), realizaram o curso. O número de etapas cumpridas de forma correta após seis meses foi significativamente menor que logo após o curso (10,8 vs 12,5 p < 0,001). O sexo e idade não interferiram nos resultados. A qualidade global foi considerada ótima em 78% dos atendimentos realizados logo após o curso, significativamente, maior que os 40% após seis meses (p < 0,01). Após seis meses, maior número de erros foi observado nas etapas relacionadas às habilidades mais práticas (como posicionamento das mãos). Conclusão Seis meses após o curso observamos uma perda significativa das habilidades, entre estudantes de medicina, prejudicando a eficácia global do atendimento.

Abstract Background Reduction of mortality and sequelae of cardiac arrest depends on an effective and fast intervention, started as soon as possible. Basic life support involves a series of steps that may be initiated out of the hospital setting and taught to any person in specific courses. However, it is important that the rescuers retain the knowledge and skills to perform cardiopulmonary resuscitation (CPR), as one never knows when they will be required. Studies have shown that a loss of skills occurs as early as 30 days after the training course, with variations according to personal and professional characteristics. Objectives to assess whether medical students are able to retain skills acquired in a BLS course for more than six months. Methods Prospective, case-control, observational study. Medical students attended a 40-hour course on sudden death and cardiac arrest. Skills acquired during the course were evaluated immediately after and six months after the course. Students’ individual scores were compared between these time points, the percentage of correct answers was evaluated, and overall performance was rated as excellent, good, and poor. Observers and evaluation criteria were the same immediately after the course and six months later. Data were analyzed using the paired t-test and the McNemar test. The 95% confidence interval was established, and a p < 0.05 was set as statistically significant. Results Fifty students (27 female) in the first year of medical school aged from 18 to 24 years (mean of 21 years) attended the course. The number of steps successfully completed by the students at six months was significantly lower than immediately after the course (10.8 vs 12.5 p < 0.001). Neither sex nor age affected the results. Overall performance of 78% of the students was considered excellent immediately after the course, and this percentage was significantly higher than six months later (p < 0.01). After six months, the steps that the students failed to complete at six months were those related to practical skills (such as a correct hand positioning). Conclusion A significant loss of skills was detected six months after the BLS course among medical students, compromising their overall performance.

OBJETIVO: Analisar os intervalos de tempo entre o início da Fibrilação Ventricular/Taquicardia Ventricular (FV/TV) e os principais procedimentos realizados. MÉTODOS: Foram realizadas e filmadas 20 simulações de FV/TV em ambiente hospitalar, utilizando-se manequim estático, ocorridas em dia e hora aleatórios. Todas as equipes tinham o mesmo nível de habilidades. Foram analisados os tempos (em s) relativos ao suporte básico de vida (SBV) - chegada da equipe (TC) confirmação da parada (TCP) início da RCP (TI) e os tempos relativos ao suporte avançado de vida (SAV) - 1º desfibrilação (TD) 1º dose de adrenalina (TA) e intubação orotraqueal (TIOT). As variáveis foram analisadas e comparadas em dois grupos: unidade de cuidados intensivos (UCI) e enfermarias com telemetria (ETL). RESULTADOS: ETL x UCI respectivamente - TC (70,2+38,7 x 38,6+49,2); TCP (89,4+57,1 x 71+63,9); TI (166,8+81,1 x 142+66,2); TD (282,5+142,8 x 108,4+52,5); TA (401,4+161,7 x 263,3+122,8) e TIOT (470,3+150,6 x 278,8+98,8). Apresenta a comparação das médias de tempos entre os dois grupos. CONCLUSÃO: As diferenças observadas em relação a TD, TA e TIOT favoráveis à UCI estão associadas às facilidades de realização das manobras de SAV nesse ambiente. Os tempos relacionados ao SBV foram semelhantes nos dois grupos, reforçando a necessidade do uso de desfibriladores semi-automáticos mesmo em ambiente hospitalar.

OBJECTIVE: To analyze the time intervals between the beginning of the Ventricular Fibrilation/Ventricular Taquicardia (VF/VT) and the main procedures made. METHODS: Twenty VF/VT simulations were performed and filmed in a hospital environment, using a static mannequin, on random days at random times. All teams had the same level of skills. The times (in sec.) related to basic life support (BLS) - arrival of the team (AT), confirmation of the arrest (CAT), beginning of the CPR (IT) and the times related to the advanced life support (ALS) - 1st defibrillation (DT), 1st dose of adrenalin (AT) and orotracheal intubation (OTIT). The variables were analyzed and compared in two groups: intensive care unit (ICU) and wards with telemetry (TLW). RESULTS:The results in both groups was in that order (GW x ICU ) - AT (70.2+38.7 x 38.6+49.2); CCA (89.4+57.1 x 71+63.9); SC (166.8+81.1 x 142+66.2); FD (282.5+142.8 x 108.4+52.5); FE (401.4+161.7 x 263.3+122.8) e OI (470.3+150.6x278.8+98.8). Shows the comparison of the average times between the two groups. CONCLUSION: The differences noted in relation to DT, AT and OTIT favorable to ICU are associated to the facility of performance of the ALS maneuvers in such environment. The BLS-related times were similar in both groups, which reinforce the need for the use of semi-automatic defibrillators, even in a hospital environment.

Este trabalho analisa 172 pacientes consecutivos operados de cirurgia valvar e coronária simultânea, no período compreendido entre julho de 1980 e junho de 1989.0 número de pacientes submetidos a revascularização do miocárdio e tratamento cirúrgico da valva aórtica (RAo) foi de 95, sendo que 75 foram submetidos a tratamento cirúrgico da valva mitral e revascularização do miocárdio (RMi). As lesões valvares mais freqüentes foram a estenose aórtica, 44 casos de insuficiência mitral em 40 casos. O número de anastomoses por paciente foi de 1,87 em média para os pacientes RMi e de 1,56 nos pacientes RAo. A mortalidade hospitalar foi de 9,8% sendo que a mortalidade para os pacientes RAo foi de 7,3% e para os pacientes RMi foi de 12%. Não houve diferença significativa (x²=04423) entre a mortalidade dos pacientes portadores de insuficiência mitral isquémica, operados eletivamente ou em caráter de emergência, sendo a mortalidade de 20% nos eletivos e de 37,5% nos de emergência. Não houve relação entre mortalidade e número de anastomoses por paciente. Houve tendência de melhores resultados com relação à mortalidade nos pacientes RMi com cirurgia conservadora (x²=1,6382). A curva actuarial de sobrevida mostra 82,6% em 19 semestres para os pacientes RMi, 90,4% para os pacientes RAo e 86,3% para o estudo global de pacientes. Com uma evolução de 5172 meses/pacientes, 75% apresentam-se em classe funcional I (NYHA).

In the period between July 1980 and June 1989,172 consecutive patients were submitted to combined coronary and valvular surgery. There were patients with predominantly valvular indications and others with predominant coronary indications. In 95 cases, myocardial revascularization and surgical treatment of the aortic valve (RAo) were simultaneously performed. Seventy five patients were submitted to myocardial revascularization and surgical treatment of the mitral valve (RMi). The more frequent valvular lesions were aortic stenosis (44 cases) and mitral insufficiency (40 cases). The mean number of anastomoses per patient was 1,87 for RMi cases and 1,56 for RAo patients. Overall hospital mortality was 9,8%; RAo mortality was 7,3% and RMi mortality was 12%. Mortality of patients with ischemic mitral insufficiency operated on electively (20%) or in an emergency basis (37,5%) was not statistically significant (x²=04423). There was not a relationship between mortality and the number of anastomoses per patient. A tendency for better results regarding mortality was observed in RMi patients in which the valve was preserved (x²=1,6382). The survival actuarial curves in 19 semesters demonstrates a valve of 82,6% for RMi patients, 90,4% for RAo patients and 86,3% for the whole series. After evolution of 5172 months/patients, 75% were in functional class I (NYHA).
