ABSTRACT
La cardiopatía isquémica es un padecimiento que se caracteriza por la falta de oxígeno del músculo cardiaco y es la principal causa de infarto de miocardio. Existen múltiples factores que predisponen al desarrollo de ésta como la obesidad, la hiperlipidemia, el sedenta- rismo, tabaquismo, diabetes e hipertensión. Dadas las características que configuran la fisiopatología de la cardiopatía isquémica, existen diversas consideraciones que deben ser tomadas en cuenta toda vez que el estomatólogo brinde atención a un paciente con este padecimiento. El objetivo del presente artículo es conocer todo lo relacionado con la fisiopatología de la cardiopatía isquémica, sus manifestaciones clínicas, su tratamiento médico y lo más importante, las consideraciones que deben tomarse en el consultorio dental cuando se atienda a un paciente que padezca esta condición (AU)
Ischemic heart disease is a condition characterized by a lack of oxygen in the heart muscle and is the main cause of myocardial infarction. There are multiple factors that predispose to the development of this, such as obesity, hiyperlipidemia, sedentary lifestyle, smoking, diabetes and hypertension. Given the characteristics that make up the pathophysiology of ischemic heart disease, there are various considerations that must be taken into account whenever the stomatologist provides care to a patient with this condition. The objective of this article is to know everything related to the pathophysiology of ischemic heart disease, its clinical manifestation, its medical treatment and most importantly, the considerations that must be taken in the dental office when caring for a patient with this condition (AU)

As doenças cardiovasculares (DCV) são a principal causa de morte no Brasil e no mundo. As doenças isquêmicas do coração (DIC) e doenças cerebrovasculares (DCBV) estão entre as dez principais causas de mortes no Brasil. A análise de tendência da mortalidade por DCV permite definir populações prioritárias para intervenções, elaborar e avaliar ações em saúde pública. Nesse sentido, o objetivo do estudo foi analisar a tendência da mortalidade por DIC e DCBV nas 27 capitais brasileiras, no período de 1990 a 2018. Trata-se de um estudo ecológico de série temporal, os dados de óbitos foram obtidos através do Sistema de Informações sobre Mortalidade (SIM). Buscando corrigir problemas na qualidade da informação dos registros de óbito do SIM, realizou-se a correção dos óbitos referentes aos dados com sexo e/ou faixa etária ignorada e aos óbitos registrados com causas "mal definidas". As taxas de mortalidade por DIC e DBCV foram padronizadas pelo método direto, tomando-se como população padrão a população do Brasil no ano de 2010. A análise de tendência da mortalidade por DIC e DCBV para a população total, homens e mulheres foi realizada utilizando o modelo de regressão de Poisson. Os resultados mostraram tendência de redução da mortalidade por DCBV tanto para a população total como para homens e mulheres em todas as capitais brasileiras. Vitória, capital da região Sudeste, apresentou a maior redução da taxa de mortalidade total por DCBV dentre todas as capitais brasileiras, -5,6% ao ano (IC95%: -6,0; -5,1%). No entanto, Macapá, capital da região Norte, teve a menor dentre todas as capitais -1,7% ao ano (IC95%: -2,7; -0,7%). Paras as DIC foi observada tendência de redução da mortalidade tanto para a população total como para homens e mulheres nas capitais das regiões Sul, Sudeste e para a maioria das capitais da região Centro-Oeste. As capitais das regiões Norte e Nordeste apresentaram uma variabilidade na tendência da mortalidade por DIC. Conclui-se que as capitais das regiões Sul e Sudeste apresentaram as maiores reduções da tendência da mortalidade por DIC e DCBV. Os achados desse estudo são importantes para prover informações mais detalhadas buscando auxiliar a gestão local na promoção de políticas de saúde pública, planejamento de estratégias e elaboração de medidas e ações em saúde.
Cardiovascular diseases (CVD) are the leading cause of death in Brazil and worldwide. Ischemic heart diseases (IHD) and cerebrovascular diseases (CBVD) are among Brazil's ten main causes of death. The trend analysis of mortality from CVD allows defining priority populations for interventions, designing and evaluating public health actions. In this sense, the study's objective was to analyze the mortality trend from IHD and CBVD in the 27 Brazilian capitals from 1990 to 2018. This is an ecological time-series study with the Mortality Information System (SIM) data. Seeking to correct the quality of the information in the SIM death records, the correction of deaths referring to data with anonymous sex and age group and deaths recorded with "ill-defined" causes was carried out. IHD and CBVD mortality rates were standardized by the direct method, using the population of Brazil in 2010 as the standard population. Trend analysis of IHD and CBVD mortality for the total population, men and women, was performed using the Poisson regression model. The results showed a reduction in the trend of mortality from CBVD for both the total population and for men and women in all Brazilian capitals. Vitória, the capital of the Southeast region, showed the greatest reduction in the total mortality rate from CVD among all Brazilian capitals, -5.6% per year (95%CI: -6.0; -5.1%). However, Macapá, the capital of the North region, had the lowest among all capitals -1.7% per year (95%CI: -2.7; -0.7%). For IHD, a decrease in the mortality trend was observed both for the total population and for men and women in the capitals of the South and Southeast regions and most capitals of the Center-West region. The capitals of the North and Northeast regions showed variability in the trend of IHD mortality. In conclusion, the capitals of the South and Southeast regions showed the greatest reductions in the mortality trend due to IHD and CBVD. The findings of this study are essential to provide more detailed information to assist local management in promoting public health policies, planning strategies, and designing health measures and actions.

Background: In developing countries, Ischemic heart diseases (IHD) is one of the leading causes of morbidity and mortality. The underlying pathology of CAD is atherosclerosis. When this atherosclerotic plaque ruptures, platelets play a crucial role in the prothrombotic events and forms a thrombus on this plaque and as a result coronary artery gets occluded causing ischemia and infarction. Platelet contains many chemokines, cytokines and growth factors. Release of these factors along with interaction with endothelial cells and leukocytes promotes inflammation and progression of atherosclerosis. We aimed to investigate the association between platelet volume indices in patients with diagnosis of Ischemic heart disease in comparison with control group.Methods: By using automated cell counter platelet count and platelet volume indices - were compared with Normal healthy or non-cardiac chest pain patients with the use of unpaired t test.Results: In the present study, we demonstrated that platelet count is significantly low and MPV and PDW are significantly high in Ischemic heart disease as compared to patients with noncardiac chest pain or healthy subjects. The correlation of MPV with PC revealed an inverse correlation between the patients of IHD and healthy or non-cardiac chest pain patients which is statistically significant.Conclusions: The platelet volume indices are an important, simple, effortless and a cost-effective tool useful in predicting the development of an acute coronary event sometimes in the near future and therapeutic modification for improved patient’s cardiovascular care.
ABSTRACT
Objective To establish a cell line stably expressing the tissue plasminogen activator (TPA) in human skin fibroblasts so as to develop the function analysis and gene therapy of TPA in ischemic heart diseases. Methods Eukaryotic expression vector pcDNA3.1(+)TPA was constructed and transferred into human skin fibroblasts. After G418 selection, the exogenous expression and activity of TPA were observed subsequently by reverse transcription-polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), and chromogenic substrate assay. Results Eukaryotic expression vector pcDNA3.1(+)TPA was expressed effectively in human skin fibroblasts. Quantitative ELISA showed that the expression of TPA protein of the experiment group was much higher than that of the hours). And the chromogenic substrate assay showed that the exogenous TPA activity of the experimental group was also much higher than that of the hours). Conclusion The exogenous TPA gene can be expressed effectively after pcDNA3.1(+)TPA was transferred into human skin fibroblasts, suggesting that the cell model will become an important tool in the further study of TPA function and gene therapy in ischemic heart diseases.
