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: O conhecimento das variáveis preditoras de mortalidade é importante para a prática clínica e para o acompanhamento terapêutico na doença da valva mitral. Objetivos: Determinar se um escore de qualidade de vida avaliado com o Functional Evaluation of Cardiac Health poderia auxiliar na predição de mortalidade em cães com doença degenerativa da valva mitral (DDVM). Métodos: Trinta e seis cães de estimação com doença valvar mitral foram submetidos a avaliação clínica, laboratorial e ecocardiográfica no início do estudo e monitorizados durante 6 meses. A morte cardiovascular foi o desfecho primário. Resultados: Os 36 cães foram classificados como sobreviventes ou não sobreviventes. Os valores mais elevados das seguintes variáveis foram obtidos no início do estudo no grupo de não sobreviventes (12 cães): fragmento N-terminal do peptídeo natriurético tipo B (NT-proBNP), norepinefrina plasmática, frequência cardíaca, escore de qualidade de vida, razão da dimensão interna diastólica do ventrículo esquerdo e raiz aórtica, razão da dimensão interna sistólica do ventrículo esquerdo e raiz aórtica e a relação da dimensão do átrio esquerdo e a raiz aórtica. Concentrações de NT-proBNP e o escore de qualidade de vida foram independentemente associados com morte na análise multivariada. Conclusão: O escore de qualidade de vida foi uma variável independente para a morte por doença cardíaca em cães com DDVM. Este resultado é encorajador, pois este escore é de fácil aplicação e não requer o emprego de tecnologia, necessitando apenas de um veterinário e um dono observador.

Abstract Background: The knowledge of the variables predicting mortality is important in clinical practice and for therapeutic monitoring in mitral valve disease. Objectives: To determine whether a quality of life score evaluated with the Functional Evaluation of Cardiac Health questionnaire would predict mortality in dogs with degenerative mitral valve disease (DMVD). Methods: Thirty-six client-owned dogs with mitral valve disease underwent clinical, laboratory, and echocardiographic evaluations at baseline and were monitored for 6 months. Cardiovascular death was the primary outcome. Results: The 36 dogs were classified as survivors or nonsurvivors. Higher values of the following variables were obtained at baseline in the nonsurviving group (12 dogs): amino-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, plasma norepinephrine, heart rate, quality of life score, diastolic left ventricular internal dimension to aortic root ratio, systolic left ventricular internal dimension to aortic root ratio, and left atrium to aortic root ratio. NT-proBNP levels and quality life score were independently associated with death in the multivariable analysis. Conclusion: The quality life score was an independent variable for cardiac death in dogs with DMVD. This result is encouraging, as this score is easy to apply and does not require any technology, only a veterinarian and an observant owner.

Convulsões sociais associadas a catástrofes como enchentes, terremotos e ataques aéreos apresentam maior incidência de infarto do miocárdio. A morte prematura de personagens da mídia com forte apelo popular podem representar fenômenos semelhantes. OBJETIVOS: Analisar o impacto da mídia sobre o serviço de atendimento de emergência do InCor. MÉTODOS: Através do banco de dados do InCor, foi analisado o perfil demográfico dos pacientes atendidos nos dias subseqüentes às repercussões na imprensa leiga da morte por infarto agudo do miocárdio de um importante personagem da mídia (Grupo Bussunda). Esses pacientes foram comparados com um Grupo Controle representado pelos atendimentos no primeiro semestre de 2006. RESULTADOS: Comparado ao Grupo Controle, o grupo Bussunda (Grupo B) apresentou mudanças que foram estatisticamente significativas e foram representadas pela redução da faixa etária e pelo aumento do número de homens atendidos em relação a mulheres. Este achado refletiu uma aproximação do primeiro grupo com o perfil do personagem em questão (homem, 43 anos de idade). Estas mudanças persistiram por quatro dias em relação à idade e por um dia em relação ao gênero. Apesar do aumento absoluto dos atendimentos, não ocorreu aumento do número de óbitos e de internações por infarto do miocárdio. CONCLUSÃO: A divulgação pela mídia das circunstâncias e da morte prematura por infarto agudo do miocárdio de um personagem importante provocou aumento do número de atendimentos e alterações do perfil demográfico dos pacientes que procuram o serviço de emergência cardiológica, sem que houvesse interferência no número de óbitos ou de internações.

INTRODUCTION: Social turmoil associated with catastrophes such as flooding, earthquakes or air raids bring about an increased incidence of acute myocardial infarction. Premature death of media personalities with a strong public appeal may cause similar phenomena. OBJECTIVE: To analyze the impact of this media coverage on the emergency service at a Heart Hospital in Brazil (InCor). METHODS: Demographic profiles of patients collected from the InCor's database were analyzed in the days following the death of an important TV personality (Group B). These patients were compared to a Control Group represented by those attended during the first semester of 2006. RESULTS: When compared to the Control Group, Group B disclosed the following significant statistical changes: patients were younger and more of them were male. These findings reflect a change of profile in the control group tending to a greater similarity with the characteristics of the TV personality (man, 43 years old). These changes remained significant for four days (age) and one day (gender). Furthermore, the greater demand for the cardiologic emergency service was not followed by an increased number of deaths and hospitalizations for acute myocardial infarction. CONCLUSION: Media exposure on the circumstances of premature death by myocardial infarction of an important TV personality was associated with an increase in the number and a change in the profile of the patients seeking the emergency room at the InCor Heart Hospital. Differently from a situation such as catastrophes, this phenomenon was not followed by an increase in the incidence of myocardial infarction

O uso de artéria torácica interna esquerda para descendente anterior se tornou fundamental na revascularização do miocárdio. Este enxerto levou ao aumento da utilização de enxertos arteriais, dos quais a artéria radial é muito popular. O uso de artéria radial em pacientes de emergência foi pouco estudado. Este estudo compara a evolução clínica imediata entre revascularização do miocárdio eletiva vs. emergência com artéria torácica interna esquerda e artéria radial. MATERIAL E MÉTODOS: Estudo retrospectivo de 47 pacientes que se submeteram a revascularização do miocárdio eletiva ou de emergência entre 1996 e 2003. Apresentavam estenose crítica (>70%) em todas as artérias alvo. Apenas a artéria torácica interna esquerda e a artéria radial foram utilizadas. Os pacientes constituíram dois grupos: eletivo (23 casos) e emergência (24 casos). Critérios de emergência foram angina instável e/ou estenose coronariana crítica com alto risco de infarto agudo do miocárdio. Os grupos eram homogêneos para idade e artérias acometidas. RESULTADOS: A média de enxertos de artéria torácica interna esquerda por paciente eletivo e de emergência foi respectivamente 1,17 e 1,38 (P=.17). A média de enxertos de artéria radial por paciente eletivo e de emergência foi respectivamente 2,26 e 2,08 (P=.48). A mortalidade até 30 dias foi zero. No pós-operatòrio não ocorreram casos de choque cardiogênico. Um paciente eletivo (4,4%) e 5pacientes de emergência (20,8%) apresentaram infarto agudo do miocárdio no pós-operatório; tendência não significativa para ocorrência de infarto agudo do miocárdio no grupo de emergência (P=.18). Tempo de internação na unidade de terapia intensiva e hospitalar foi semelhante nos dois grupos. CONCLUSÃO: A revascularização do miocárdio com utilização de artéria torácica interna esquerda e artéria radial pode ser realizada em pacientes de emergência com resultados equivalentes aos pacientes eletivos.

BACKGROUND: Left internal thoracic artery-to left anterior descending artery grafting has become a fundamental part of coronary artery bypass grafting. This grafting has led to increased use of other arterial conduits, of which the radial artery is most popular. Whether radial grafting can be used in the emergency patient is not known. This study compares the short-term clinical evolution between elective vs emergency coronary artery bypass grafting surgery with left internal thoracic artery and radial artery. METHODS: A retrospective study of 47 patients who underwent elective or emergency coronary artery bypass grafting from 1996 to 2003. All patients had coronary stenosis >70% in all target vessels. Only the left internal thoracic artery and radial artery were used as grafts. Patients were divided into elective group (23 patients) and emergency group (24 patients). Emergency criteria were unstable angina and/or critical coronary stenosis with high risk for acute myocardial infarction. Groups were similar for age and number of diseased vessels. RESULTS: The mean number of left internal thoracic artery grafts per patient in the elective and emergency groups were respectively 1.17 and 1.38 (P = .17). The mean number of radial artery grafts per patient in the elective and emergency groups was respectively 2.26 and 2.08 (P = .48). The 30-day mortality was 0. There was no postoperative cardiogenic shock. The elective group had 1 acute myocardial infarction (4.4%) postoperatively, and emergency group had 5 (20.8%). A nonsignificant trend towards acute myocardial infarction was noted in the emergency group (P = .18). Intensive care unit and postoperative stay were similar in both groups. CONCLUSION: Coronary artery bypass grafting using left internal thoracic artery and radial artery accomplishing complete revascularization can be performed in emergency patients with results similar to those for elective patients.

OBJECTIVE: To assess the clinical and demographic characteristics of a population with ischemic heart disease admitted in the final decades of the 20th century. METHODS: This study retrospectively assessed patients hospitalized with ischemic heart disease divided into the following 2 groups: acute group - 11.181 patients with acute myocardial infarction admitted from 1/1/82 to 12/31/94; and chronic group - 4.166 patients undergoing coronary artery bypass graft surgery from 1/1/84 to 12/31/94. RESULTS: In the acute group, an increase in the percentage of females (from 22.7% to 27.7%, P<0.001) and diabetic individuals (from 12.4% to 17.5%, P<0.001) was observed, as was an increase in age (from 57.4±11.5 to 59.9±12.1 years, P<0.05). In-hospital mortality was greater among females (27.8% and 15.7%, P=0.001), among diabetic individuals (24.2% and 17.8%, P=0.001), and among the elderly (60.9±15.2 and 57.7±11.8 years, P=0.0001). In the chronic group, an increase in the percentage of females (from 17.5% to 27.2%, P=0.001) was observed, as was an increase in age (from 56.3±8.6 to 60.5±9.6 years, P=0.0001). In-hospital mortality was greater among females (8.3% and 5.8%, P<0.05) and among the elderly (58.1±9.1 and 62.1±7.9 years, P=0.0001). CONCLUSION: The characteristics of the population studied with ischemic heart disease point towards a worse prognosis, due to the greater percentages of females, older patients, and diabetic patients, groups known to have greater in-hospital mortality.

OBJECTIVE: To obtain information about the profile and behavior of a population with ischemic heart disease undergoing cine coronary angiography and to determine disease severity. METHODS: Retrospective study assessing patients hospitalized at InCor from 1986 to 1995, in which the variables age, sex, and number of major coronary arteries with obstruction degree > 40% were analyzed. RESULTS: We studied 18,221 patients and observed a significant increase in the number of females (22.8% to 25.2%, P=0.001) and an increase in age (57.1±29.3 to 60.4±10.7 years, P=0.0001). A significant increase in the incidence of multivessel disease was observed, which was more frequent among males (69.2% and 64.5%) and among the older patients (59.8±9.8 and 56.8±10.7 years, P=0.0001). A reduction in the incidence of single-vessel disease was also observed (66.2% vs 69.2% and 33.8% vs 30.5%, respectively, P<0.0001). CONCLUSION: A change in the profile of the population studied was observed as follows: patients undergoing cine coronary angiography at InCor were older, had a greater number of impaired major coronary arteries, and the number of females affected increased, leading to indices suggestive of a poorer prognosis.
