    Full Text Available El beriberi, la deficiencia de tiamina (B1, fue referido en el siglo XVII en la literatura asiática, y pue de manifestarse por síntomas neurológicos (beriberi «seco» donde la neuropatía periférica y la debilidad muscular son los más destacados y/o síntomas cardiovasculares (beriberi «húmedo», con una variante «clásica» donde es predominante la insuficiencia cardíaca derecha con índice cardíaco (IC normal o alto y otra aguda o «shoshin-beriberi», caracterizada por insuficiencia biventricular, acidosis láctica e IC variable y que sin tratamiento precoz evoluciona al colapso vascular y la muerte. Se presenta una paciente de 58 años y antecedente de enolismo, con disnea, oliguria, sígnos de fallo cardíaco biventricular con patrón hiperdinámico, acidosis metabólica, disfunción tubular renal y lactacidemia de 5.6 mEq/L. El exámen neurológico mostró una polineuropatía sensitiva, simétrica y distal en MMII y deterioro cognitivo con sígnos frontales. Horas después de la administración de 100 mg de tiamina ev. se observó una manifiesta mejoría de los valores hemodinámicos y el estado ácido-base. Se concluye que si bien el beriberi cardiovascular agudo es de presentación infrecuente hay consenso en que además es subdiagnosticado. La presencia de acidosis láctica o cuadro de insuficiencia cardíaca de alto volumen minuto sin etiología manifiesta, en pacientes con riesgo de deficiencia de B1, es suficiente para hacer la prueba terapéutica.Beriberi (BB, thiamine deficiency, has been described in the Asian literature in the 17th century and is characterized by peripheral neuropathy and muscle weakness, also called «dry» beriberi (BB to differentiate it from «wet» BB, with essentially cardiovascular manifestations. Wet can be either «classic» wet BB in which signs and symptons of right-sided heart failure with normal or high cardiac output are the presenting features or the «shoshin» BB variant with severe

    Full Text Available La rehabilitación cardiovascular (RC ha impuesto el criterio de constituir un medio favorable para la recuperación de los pacientes que presentan un infarto agudo de miocardio. Basado en estos datos se llevó a la práctica un programa de rehabilitación cardiovascular. El objetivo general fue comparar los resultados de las pruebas ergométricas realizadas a pacientes portadores de un infarto agudo del miocardio antes y después de la rehabilitación cardiovascular. Se realizó un estudio de intervención, longitudinal, prospectivo, que se llevó a cabo en el Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas, en el período comprendido entre enero y diciembre de 2005. A los 38 pacientes que constituyeron la muestra se les realizó una prueba ergométrica pre alta, la cual fue comparada con otra que se realizó tres meses después de comenzada la rehabilitación cardiovascular. Encontramos una disminución significativa de la positividad de las pruebas de 45 % inicialmente, a un 24 % a los tres meses de entrenamiento físico. A pesar del aumento significativo de la carga máxima tolerada, el desplazamiento del segmento ST se mantuvo igual al final del estudio. Alteraciones durante la prueba como la reacción hipertensiva, el dolor precordial típico y la presencia de arritmias disminuyeron significativamente al final del estudio. De los 38 pacientes que comenzaron el estudio, 37 se encontraban en la clase funcional I y II de la escala New York Heart Association (NYHA a los 3 meses. Al estratificar el riesgo se encontró que hubo un aumento significativo de la categoría riesgo bajo (RB a expensa de la de riesgo alto (RA. Se concluyó que hubo una mejoría significativa desde el punto de vista ergométrico de los pacientes que intervinieron en el programa de rehabilitación cardiovascular.The cardiovascular rehabilitation has imposed the criteria that it is a favourable way for the recuperation of the

To review brain MRI findings in infantile encephalitic beriberi from a single institution. A retrospective review of MRI scans in 22 infants with acute-onset beriberi encephalopathy was carried out. Hyperintense lesions on T2-weighted images were seen symmetrically in the putamen in all patients, in the caudate nuclei in 16/22 (73%), the thalami in 7/22 (32%) and the globi pallidi in 3/22 (14%) of the infants. Altered signal intensity lesions in the cerebral cortex were seen in 7/22 (32%). The mammillary bodies were seen in one infant and the periaqueductal gray matter in two. There was restricted diffusion in 14/22 (64%), and 6/8 children with no evidence of restriction had been imaged ≥10 days after presentation. MR spectroscopy showed increased lactate peak in 6/8 infants (75%). Recognition of symmetrical T2-W hyperintense lesions in the basal ganglia with restricted diffusion and prominent lactate peak may allow early diagnosis of encephalitic beriberi in at-risk infants.

  10. [The history of healing; beriberi: 'kind of paralysis'].

    1997-06-14

    Beriberi began to attract increasing attention in the second half of the 19th century, mostly due to the large numbers of victims among Dutch military personnel in the Netherlands East Indies. A study, carried out in Atjeh in 1886 by the Japanese Sugenoya and F. J. Cornelissen, led to the conclusion that there existed a beriberi bacillus which they could make visible in stained microscopical preparations. An extensive disinfection campaign in all barracks followed, but its benefits were a matter of debate. Inadequate nutrition in the investigators' eyes was only a predisposing factor. A.G. Vorderman (1844-1902) assumed a connection between rice feeding and beriberi in prisoners; he reported that the disease coincided with a diet of polished white rice. Beriberi could be prevented by providing the prisoners with 'red rice' (unpolished rice). However, red rice was regarded as inferior and status-lowering so that substitution of red for white rice in the rations was impossible. The concept of a 'lacking substance' (thiamine, vitamin B1) was hesitatingly accepted in the Netherlands. C. Winkler and C. Eijkman, for instance, refused until the early twenties of this century to exclude the possibility of a bacterial infection as the cause. As known, Eijkman in 1929 was awarded the Nobel prize for his contribution to vitamin research. PMID:9380156

    2015-01-01

    Full Text Available Background. Wernicke’s encephalopathy (WE is an acute neurological disorder resulting from thiamine deficiency. It is mainly related to alcohol abuse but it can be associated with other conditions such as gastrointestinal disorders. This vitamin deficiency can also present with cardiovascular symptoms, called “wet beriberi.” Association with folate deficit worsens the clinical picture. Subject. A 70-year-old man with gastric phytobezoar presented with gait instability, dyspnoea, chest pain associated with right heart failure and pericarditis, and folate deficiency. Furosemide was administered and cardiac symptoms improved but he soon developed vertiginous syndrome, nystagmus, diplopia, dysmetria, and sensitive and motor deficit in all four limbs with areflexia. Results. A cerebral magnetic resonance imaging (MRI showed typical findings of WE. He was immediately treated with thiamine. Neurological symptoms improved in a few days and abnormal signals disappeared in a follow-up MRI two weeks later. Conclusion. Patients with malabsorption due to gastrointestinal disorders have an increased risk of thiamine deficiency, and folate deficiency can make this vitamin malabsorption worse. An established deficiency mainly shows neurological symptoms, WE, or rarely cardiovascular symptoms, wet beriberi. Early vitamin treatment in symptomatic patients improves prognosis. We recommend administration of prophylactic multivitamins supplements in patients at risk as routine clinical practice.

    Full Text Available Infantile beriberi (thiamine deficiency occurs mainly in infants breastfed by mothers with inadequate intake of thiamine, typically among vulnerable populations. We describe possible and probable cases of infantile thiamine deficiency in northern Laos.Three surveys were conducted in Luang Namtha Province. First, we performed a retrospective survey of all infants with a diagnosis of thiamine deficiency admitted to the 5 hospitals in the province (2007-2009. Second, we prospectively recorded all infants with cardiac failure at Luang Namtha Hospital. Third, we further investigated all mothers with infants (1-6 months living in 22 villages of the thiamine deficiency patients' origin. We performed a cross-sectional survey of all mothers and infants using a pre-tested questionnaire, physical examination and squat test. Infant mortality was estimated by verbal autopsy. From March to June 2010, four suspected infants with thiamine deficiency were admitted to Luang Namtha Provincial hospital. All recovered after parenteral thiamine injection. Between 2007 and 2009, 54 infants with possible/probable thiamine deficiency were diagnosed with acute severe cardiac failure, 49 (90.2% were cured after parenteral thiamine; three died (5.6%. In the 22 villages, of 468 live born infants, 50 (10.6%, 95% CI: 8.0-13.8 died during the first year. A peak of mortality (36 deaths was reported between 1 and 3 months. Verbal autopsy suggested that 17 deaths (3.6% were due to suspected infantile thiamine deficiency. Of 127 mothers, 60 (47.2% reported edema and paresthesia as well as a positive squat test during pregnancy; 125 (98.4% respected post-partum food avoidance and all ate polished rice. Of 127 infants, 2 (1.6% had probable thiamine deficiency, and 8 (6.8% possible thiamine deficiency.Thiamine deficiency may be a major cause of infant mortality among ethnic groups in northern Laos. Mothers' and children's symptoms are compatible with thiamine deficiency. The severity

  15. A Retrospective Investigation of Thiamin and Energy Intakes Following an Outbreak of Beriberi in the Gambia

    Full Text Available In the early part of the rainy season in 1988, an outbreak of beriberi occurred in free-living adults in a relatively small area in the North Bank region of The Gambia. In 1995 we selected two compounds in a village called Chilla situated within the affected district to retrospectively examine dietary factors potentially contributing to the outbreak. There had previously been cases of beriberi in one compound (BBC but not in the other (NBC. We measured energy and thiamin intakes for four days on six occasions during the year. We calculated energy and thiamin intakes of people living in the two compounds and foods were collected for thiamin analysis through the year. Thiamin:Energy ratios only met international recommendations in the immediate post‑harvest season when energy and thiamin intakes were highest and then fell through the year. In the rainy season when food was short and labour was heaviest, energy intakes were lower in the NBC but thiamin:energy ratios were lower in BBC. Records of rainfall in 1988 collected near the village indicated that the amount in August was twice the average. We suggest the heavy rainfall may have increased farm workload and reduced income from outside-village work activity. The lower energy intakes in the NBC may have forced adults to rest thus sparing thiamin demands and delaying onset of beriberi. In contrast, the higher energy intake of adults in the BBC may have enabled them to continue working, thus increasing demands for thiamin and inducing the earlier onset of beriberi.

    2010-12-01

    Full Text Available Abstract Introduction We describe a case of rapidly progressive and severely debilitating polyneuropathy in a patient with confirmed hypovitaminosis B1, consistent with dry beriberi. Crucially, this is a treatable condition, although sometimes with incomplete recovery, but it is probably under-recognized yet increasingly common given increasing levels of alcohol abuse in the western world. Case presentation A 49-year-old Caucasian British man presented with progressive weakness of both lower limbs of approximately seven months' duration. He noted difficulty climbing stairs. He also complained of lethargy, and loss of muscle bulk, including his thighs. He had a history of type 2 diabetes mellitus and admitted prior alcohol abuse but denied excessive alcohol intake in the five years prior to presentation. Initial clinical and neurophysiological examinations were consistent with a mild peripheral neuropathy and probable proximal myopathy. However, over the subsequent four months he evolved a marked tetraparesis, with profound sensory disturbance of all limbs. Repeat neurophysiology revealed a widespread polyneuropathy with extensive acute and sub-acute denervation changes in all four limbs, and reduced or absent sensory nerve action potentials. Hypovitaminosis B1 was confirmed (45 nmol/L, reference range 66-200 nmol/L. His rapid clinical deterioration was in keeping with dry beriberi. He was treated with thiamine. Subsequent follow-up revealed slow but significant improvement, such that by 15-16 months from the initial onset of symptoms, and approximately six months after the onset of his marked tetraparesis, he was able to stand independently and was gradually gaining confidence in walking pending a period of in-patient neurorehabilitation. Conclusion A potentially wide differential diagnosis exists for this type of presentation. Confirming hypovitaminosis B1 by requesting the assay prior to vitamin replacement ensures accurate diagnosis and

    Full Text Available La hiperglucemia con o sin diabetes preexistente es un hallazgo frecuente en pacientes que cursan un síndrome coronario agudo. Estudios previos han demostrado que la hiperglucemia es altamente prevalente y se asocia a un mayor riesgo de muerte y complicaciones hospitalarias. Los mecanismos fisiopatológicos mediante los cuales la hiperglucemia provoca resultados adversos no son claros, y se desconoce si es un marcador de eventos o su causa. Los efectos perjudiciales de la hiperglucemia en el sistema cardiovascular son múltiples, y el control de los niveles de glucosa con insulina parece mejorar el pronóstico en estos pacientes. Se han desarrollado numerosos protocolos para el control de glucemia que demostraron ser seguros y efectivos. En una iniciativa originada en el Consejo de Emergencias de la Sociedad Argentina de Cardiología, se convocó a expertos de nuestro medio con el propósito de debatir estrategias para el control de la glucemia en pacientes que cursan un síndrome coronario agudo. Este documento refleja lo discutido en este evento académico con la intención de resumir los principales aspectos del control de la glucemia y ofrecer recomendaciones generales de tratamiento en la Unidad Coronaria.

    Full Text Available Fundamento: la detección de calcio en las arterias coronarias confirma la presencia de aterosclerosis y ha demostrado ser una herramienta útil para estratificar el riesgo cardiovascular. Objetivo: determinar la relación entre la presencia y severidad de calcio coronario con la aparición de eventos coronarios agudos. Métodos: se realizó un estudio observacional, descriptivo, prospectivo, tipo serie de casos, en el Hospital Universitario Dr. Gustavo Aldereguía Lima de Cienfuegos, entre enero y diciembre de 2008. La serie estuvo conformada por 137 pacientes, en los que se estudió: sexo, antecedentes patológicos personales, cifras de glucemia en ayunas, creatinina, colesterol total y triglicéridos. Los pacientes fueron seguidos durante dos años para evaluar la aparición de eventos coronarios agudos. Resultados: La edad media fue de 53,2±7,4 años, con predominio del sexo masculino (52,5 %. El mayor porciento de pacientes clasificados como de alto riesgo, según la cuantificación del calcio coronario (16,8 % perteneció al sexo masculino, predominando en los mayores de 70 años. La diabetes se relacionó de forma significativa con la severidad del puntaje de calcio. El infarto agudo del miocardio fue más frecuente en pacientes con puntaje de calcio mayor de 400 unidades Agatston. Conclusiones: la aparición de eventos coronarios agudos fue más frecuente en los pacientes de alto riesgo según cuantificación del calcio coronario.

    Full Text Available Justificación: el infarto agudo del miocardio es un problema mayor de salud pública. Es necesario verificar su adecuado registro en Costa Rica para atender eficientemente su problemática. Materiales y métodos: estudio descriptivo y observacional. Se recopilaron los pacientes egresados del Hospital México con diagnósticos de síndrome coronario agudo, infarto agudo del miocardio, angina inestable y cardiopatía isquémica, de agosto 2005 a julio 2006, analizándose los registros de la oficina de Bioestadística y Unidades (Coronaria, Terapia Intensiva, Hemodinamia y Ecocardiogramas. Resultados: el Hospital México reportó 110 pacientes con el diagnóstico de infarto agudo del miocardio. Al incluir egresados con diagnósticos de síndrome coronario agudo, angor inestable o cardiopatía isquémica y que eran infartos agudos del miocardio, el número aumentó a 172. La muestra analizada finalmente fue de 138 pacientes al eliminar el restante por datos incompletos, significando un subregistro de al menos 36%. El 78.1% fueron hombres y la edad promedio para ambos sexos fue 65.2 años. No se le midió la troponina al 49,3% de la muestra y la cuarta parte no fueron valorados por cardiólogos. El 20.3% de los pacientes que fueron egresados con otros diagnósticos eran portadores también de infarto agudo del miocardio. Conclusiones: existe subregistro de infarto agudo del miocardio en el Hospital México y en oficinas centrales del Ministerio de Salud y la Caja Costarricense de Seguro Social. Este hallazgo también es probable que se presente en otros hospitales costarricenses.

OBJETIVOS: Verificar os efeitos do exercício físico aeróbio agudo sobre as concentrações de CK e FA, bem como, avaliar o estado hídrico em ratos diabéticos experimentais. MATERIAIS E MÉTODOS Foram utilizados ratos Wistar machos, adultos jovens, distribuídos em dois grupos: diabéticos (DA e controles (CA. O diabetes foi induzido por meio da administração de aloxana monoidratado Sigma(r (32 mg/kg de peso corporal. Duas semanas após confirmação do diabetes, ambos os grupos foram submetidos a uma sessão aguda de natação por 30 min, com carga aeróbia (4,5 % do peso corporal. Foram avaliados: glicose, hematócrito, CK, FA, albumina e a cinética de lactato durante o exercício por meio de coletas 25 µL de sangue da cauda dos animais, nos minutos 0, 10, 20 e 30 de exercício. RESULTADOS: ANOVA de dois fatores para medidas repetidas e o teste post hoc de Tukey apontaram diminuição significativa dos valores de glicemia após o exercício para o grupo DA, aumento significativo de CK pós-exercício para o grupo DA, aumento significativo de hematócrito para ambos os grupos após exercício e manutenção da FA após exercício para o grupo DA. CONCLUSÃO: O exercício agudo aeróbio foi eficiente no controle dos níveis glicêmicos de ratos diabéticos. Entretanto, deve ser aplicado com cautela, pois induziu altos valores de CK, sugerindo possíveis lesões teciduais.

  17. The Emerging Role of Cardiovascular Magnetic Resonance Imaging in the Evaluation of Metabolic Cardiomyopathies.

    2015-08-01

    The aim of this review is to discuss the role of Cardiovascular Magnetic Resonance (CMR) in the diagnosis, risk stratification, and follow-up of metabolic cardiomyopathies. The classification of myocardial diseases, proposed by WHO/ISFC task force, distinguished specific cardiomyopathies, caused by metabolic disorders, into 4 types: 1) endocrine disorders, 2) storage or infiltration disorders (amyloidosis, hemochromatosis and familial storage disorders), 3) nutritional disorders (Kwashiorkor, beri-beri, obesity, and alcohol), and 4) diabetic heart. Thyroid disease, pheochromocytoma, and growth hormone excess or deficiency may contribute to usually reversible dilated cardiomyopathy. Glucogen storage diseases can be presented with myopathy, liver, and heart failure. Lysosomal storage diseases can provoke cardiac hypertrophy, mimicking hypertrophic cardiomyopathy and arrhythmias. Hereditary hemochromatosis, an inherited disorder of iron metabolism, leads to tissue iron overload in different organs, including the heart. Cardiac amyloidosis is the result of amyloid deposition in the heart, formed from breakdown of normal or abnormal proteins that leads to increased heart stiffness, restrictive cardiomyopathy, and heart failure. Finally, nutritional disturbances and metabolic diseases, such as Kwashiorkor, beri-beri, obesity, alcohol consumption, and diabetes mellitus may also lead to severe cardiac dysfunction. CMR, through its capability to reliably assess anatomy, function, inflammation, rest-stress myocardial perfusion, myocardial fibrosis, aortic distensibility, iron and/or fat deposition can serve as an excellent tool for early diagnosis of heart involvement, risk stratification, treatment evaluation, and long term follow-up of patients with metabolic cardiomyopathies.

    Full Text Available Objetivo: En algunos Servicios de Emergencias de la CCSS, a los pacientes con infarto agudo de miocardio se les administra una dosis alta -aunque variable- de lovastatina en las primeras horas de evolución de los síndromes coronarios agudos, con la expectativa de lograr efectos pleiotrópicos, un resultado positivo sobre el endotelio y la disminución de mediadores inflamatorios. Analizar la evidencia científica que sustenta el beneficio de esta intervención farmacológica y clarificar la posible dosis oral y el potencial intervalo idóneo. Búsqueda vía electrónica en sistemas secundarios de información científica y análisis de fuentes primarias, con énfasis en ensayos clínicos aleatorizados que evalúen la eficacia de las estatinas en los eventos coronarios agudos; también de fuentes terciarias, específicamente revisiones sistemáticas y guías de consenso para práctica clínica basadas en evidencia y revisiones por instancias evaluadoras de tecnologías con reconocimiento internacional. Resultados: Cuatro ensayos clínicos aleatorizados controlados con placebo, no demostraron diferencias significativas ni clínicamente relevantes en la variable primaria combinada: evento cardiaco mayor, muerte, IAM recurrente fatal, AVC fatal u otra causa de muerte cardiovascular, ninguno usó dosis de carga, ni se inició la administración en las 24 hs del inicio de la sintomatología. Conclusión: Ante la falta de evidencia que permita proyectar con claridad un papel beneficioso para las estatinas en el manejo inicial del síndrome coronario agudo, esta práctica desequilibra la relación beneficio/riesgo y se aleja de los principios del uso racional de medicamentos y la aplicación del paradigma de la medicina basada en evidencia.

La mortalidad por la enfermedad oscila entre 15 y 50%. Aunque en Argentina un concentrado plasmático de C1 inhibidor (pdC1INH ha estado aprobado y disponible por décadas para el tratamiento del ataque agudo, solo 15 (26% de 58 pacientes había recibido pdC1INH alguna vez hasta el año 2008, y solo 2(3.4% lo usaban regularmente. Luego de la aprobación de los nuevos medicamentos para HAE, incluido el icatibant en Argentina y de la publicación de las guías terapéuticas, 42 (82% de 51 pacientes del grupo original tienen pdC1INH para tratar el próximo ataque. Sin embargo, 16 (18% de estos pacientes continúan sin acceso a la medicación y otros 15 (35.7% acceden a través de otro enfermo en forma espuria. Solo 12 (28.6% de los pacientes con el medicamento puede auto tratarse en su domicilio. La mejora en el acceso a la medicación es importante pero debe extenderse a todos los afectados y facilitarse el auto-tratamiento.

    Full Text Available La relación entre las infecciones respiratorias producidas por el virus de la influenza y el neumococo y los eventos cardiovasculares motivaron la reunión de un grupo interdisciplinario (cardiólogos, clínicos e infectólogos, con el objeto de analizar la evidencia entre la asociación de estos fenómenos y el rol de las estrategias de inmunización en la prevención de la enfermedad cardiovascular. El presente documento sintetiza las conclusiones del grupo de trabajo. El análisis de revisiones sistemáticas sugiere una evidencia consistente entre la infección por influenza y neumococo como desencadenantes de infarto agudo de miocardio y muerte cardiovascular. Los estudios publicados en los últimos 15 años sugieren que la vacunación para influenza y neumococo reducen el riesgo de síndromes coronarios agudos. Con la evidencia existente y teniendo en cuenta los análisis de costo-efectividad, ahorro de costos y perfil de seguridad de las vacunas, las sociedades científicas y agencias gubernamentales de salud, tanto nacionales como internacionales, recomiendan fuertemente la incorporación de la inmunización en el grupo de pacientes con enfermedad cardiovascular crónica.

É pertinente que estudos sobre seu ressurgimento no país sejam aprofundados.This study aimed to describe the epidemiological profile of beriberi cases and related deaths reported from 2006 to 2008 in Maranhão State, Brazil. Data were obtained from beriberi notification forms at the State Health Department. The global Moran index was used to evaluate spatial auto-correlation. 1207 cases and 40 deaths were reported. The western and central regions of the State showed strong spatial auto-correlation of incidence rates. Cases and deaths were concentrated from May to August, in young men (20-40 years. Regular alcohol consumption and smoking were recorded among fatal cases. Low income and heavy labor were widespread among cases. Common symptoms were asthenia, numbness, and swollen legs, difficulty walking, and calf pain. The profile of cases and their symptoms (except swollen legs are characteristic of dry beriberi. We recommend further studies on the resurgence of beriberi in Brazil.

    Full Text Available RESUMOA síndrome do desconforto respiratório agudo é uma patologia de início agudo, marcada por hipoxemia e infiltrados na radiografia de tórax, acometendo tanto adultos quanto crianças de todas as faixas etárias. Ela é causa importante de insuficiência respiratória em unidades de terapia intensiva pediátrica associada a significativa morbidade e mortalidade. Apesar disso, até recentemente, as definições e os critérios diagnósticos para síndrome do desconforto respiratório agudo centravam-se na população adulta. No presente artigo, revisamos a evolução da definição da síndrome do desconforto respiratório agudo ao longo de quase cinco décadas, com foco especial na nova definição pediátrica. Discutimos ainda recomendações relativas à aplicação de estratégias de ventilação mecânica no tratamento da síndrome do desconforto respiratório agudo em crianças, assim como o uso de terapias adjuvantes.

    Full Text Available Baixo peso ao nascer, fator de risco recentemente descrito para as doenças cardiovasculares, está associado com mortalidade infantil elevada. Foram comparadas as taxas de mortalidade por infarto agudo do miocárdio no ano 2000, registradas nas regiões Nordeste e Sul do Brasil, com os coeficientes de mortalidade infantil entre os anos 1930/1950. Entre os anos 1930/1950, o Nordeste apresentava um coeficiente médio de mortalidade infantil de 185 por mil nascidos vivos, e a Região Sul, 116 por mil nascidos vivos. Observou-se uma maior mortalidade por infarto agudo do miocárdio na Região Sul (coeficientes ajustados de 60,8 e 41,2 vs. 26,4 e 19,2 por 100 mil habitantes, respectivamente para o sexo masculino e feminino. A desigualdade entre as taxas de mortalidade infantil no Nordeste e Sul no período estudado, ao lado de que o fenômeno da redução da mortalidade infantil não ter representado melhorias importantes das condições de vida, impediu a avaliação do impacto do baixo peso ao nascer sobre as taxas de mortalidade por infarto agudo do miocárdio na vida adulta.Low birth weight is a risk factor for cardiovascular diseases, which constitute the main causes of death both in Brazil and worldwide. High infant mortality rates are associated with low birth weight. The aim of this study was to compare mortality from acute myocardial infarction in 2000 in the Northeast and South of Brazil, regions with different infant mortality rates from 1930 to 1950. Mortality from acute myocardial infarction was higher in southern Brazil, with an adjusted coefficient per 100,000 of 60.8 in males and 41.2 in females (South versus 26.4 in males and 19.2 in females (Northeast.

    Full Text Available Uma condição clínica muito comum é SAOS, que está associada a várias doenças cardiovasculares, incluindo hipertensão arterial sistêmica, fibrilação atrial e aterosclerose. A associação entre SAOS e doença cardiovascular não é somente uma consequência da sobreposição de fatores de risco, incluindo obesidade, sedentarismo, ser do sexo masculino e ter idade maior. Existem evidências crescentes de que SAOS contribui de forma independente para o aparecimento e a progressão de várias doenças cardiovasculares. Os mecanismos pelos quais SAOS pode afetar o sistema cardiovascular são múltiplos e incluem a ativação do sistema nervoso simpático, inflamação sistêmica, resistência a insulina e geração de estresse oxidativo. Existem evidências que o tratamento de SAOS com CPAP pode reduzir a pressão arterial, sinais precoces de aterosclerose, risco de recorrência de fibrilação atrial e mortalidade, principalmente por acidente vascular cerebral e infarto agudo do miocárdio, em pacientes com SAOS grave.Obstructive sleep apnea syndrome (OSAS is a common condition associated with various cardiovascular diseases, including systemic arterial hypertension, atrial fibrillation, and atherosclerosis. The association between OSAS and cardiovascular disease has been related to the overlapping of risk factors, including obesity, having a sedentary lifestyle, being male, and being older. However, there is mounting evidence that OSAS can also independently contribute to the development and progression of various cardiovascular diseases. The mechanisms by which OSAS can affect the cardiovascular system are multiple, including the activation of the sympathetic nervous system, systemic inflammation, insulin resistance, and oxidative stress. There is also evidence that the treatment of OSAS with CPAP can reduce arterial blood pressure, early signs of atherosclerosis, the risk of atrial fibrillation recurrence, and mortality (principally

    As a starting point, the group defined a primary goal of maintaining in flight a level of systemic oxygen transport capacity comparable to each individual's preflight upright baseline. The goal of maintaining capacity at preflight levels would seem to be a reasonable objective for several different reasons, including the maintenance of good health in general and the preservation of sufficient cardiovascular reserve capacity to meet operational demands. It is also important not to introduce confounding variables in whatever other physiological studies are being performed. A change in the level of fitness is likely to be a significant confounding variable in the study of many organ systems. The principal component of the in-flight cardiovascular exercise program should be large-muscle activity such as treadmill exercise. It is desirable that at least one session per week be monitored to assure maintenance of proper functional levels and to provide guidance for any adjustments of the exercise prescription. Appropriate measurements include evaluation of the heart-rate/workload or the heart-rate/oxygen-uptake relationship. Respiratory gas analysis is helpful by providing better opportunities to document relative workload levels from analysis of the interrelationships among VO2, VCO2, and ventilation. The committee felt that there is no clear evidence that any particular in-flight exercise regimen is protective against orthostatic hypotension during the early readaptation phase. Some group members suggested that maintenance of the lower body muscle mass and muscle tone may be helpful. There is also evidence that late in-flight interventions to reexpand blood volume to preflight levels are helpful in preventing or minimizing postflight orthostatic hypotension.

    Full Text Available OBJECTIVE: to assess cardiovascular risk by means of the traditional Framingham score and the version modified through the incorporation of emerging risk factors, such as family history of acute myocardial infarction, metabolic syndrome and chronic kidney disease. METHOD: participants were 50 hypertensive patients under outpatient treatment. The clinical data were collected through a semi-structured interview and the laboratory data from patients' histories. RESULTS: it was verified that the traditional Framingham score was predominantly low (74%, with 14% showing medium risk and 12% high risk. After the inclusion of emerging risk factors, the chance of a coronary event was low in 22% of the cases, medium in 56% and high in 22%. CONCLUSIONS: the comparison between the traditional Framingham risk score and the modified version demonstrated a significant difference in the cardiovascular risk classification, whose correlation shows discreet agreement between the two scales. Lifestyle elements seem to play a determinant role in the increase in cardiovascular risk levels.

    Full Text Available Resumen Introducción y objetivos: En Cuba las estadísticas vitales de la morbi-mortalidad por infarto agudo de miocardio proceden de pequeñas áreas de salud. El objetivo fue identificar las principales características y conducta hospitalaria de los pacientes con infarto a través de un registro hospitalario de infarto. Métodos: Se monitorizaron los casos de infarto ocurridos en pacientes de 45 a 74 años de edad y residentes en Santa Clara, durante los años 2007 y 2008. Las fuentes de información fueron: listados de egresos hospitalarios, registros hospitalarios de infarto de miocardio, certificados de defunción y registros de autopsias nosocomiales. Se utilizó la metodología MONICA (MONItoring Trends and Determinants in CArdiovascular Disease Project. Resultados: Se registraron 297 pacientes con infarto. El 62,7 % de los varones y el 46,8 % de las mujeres recibieron tratamiento de reperfusión. Las letalidades hospitalarias en varones y mujeres fueron de 25,3 % y 45 %. Las variables que se relacionaron con una mayor mortalidad fueron la edad, el sexo femenino, la frecuencia cardíaca alta, el infarto de topografía anterior, la creatinina elevada, así como los antecedentes personales de cardiopatía isquémica previa y diabetes mellitus. Mientras que el tratamiento con fibrinolíticos y/o betabloqueadores se correlacionaron inversamente con la mortalidad. Conclusiones: Existió una elevada prevalencia de dislipidemia desconocida y letalidad hospitalaria a 28 días; así como una baja utilización de las estrategias cruentas. La hipertensión sistólica al ingreso se relacionó con un mejor pronóstico. / Abstract Introduction and objectives: In Cuba, the vital statistics of morbi-mortality due to acute myocardial infarction come from small health areas.

    Full Text Available Introducción: Las enfermedades del corazón constituyen la principal causa de muerte en Cuba.Objetivos: Identificar las características clínico-epidemiológicas de los pacientes con infarto agudo de miocardio y su vínculo con la trombólisis.Método: Estudio observacional descriptivo, de corte transversal, en el Hospital Militar de Matanzas, entre enero de 2011 y enero de 2013. El universo de estudio fue de 96 pacientes con diagnóstico clínico y electrocardiográfico de infarto agudo de miocardio con supradesnivel del segmento ST.Resultados: Existió predominio del sexo masculino (61,4 %, el grupo etario más afectado fue entre 65 y 74 años (39,6 %. La hipertensión arterial constituyó el principal factor de riesgo encontrado (71,9 %. En el 60,2 % de los pacientes que recibieron tratamiento trombolítico, el tiempo puerta-aguja fue entre los 30 y 60 minutos, y la mayoría de los casos [34 (35,4 %] arribaron al hospital entre las 3 y 6 horas del inicio de los síntomas. El alivio del dolor y el regreso del ST se presentaron en el 100 % de las trombólisis efectivas. La causa más frecuente de no trombólisis fue la evolución del episodio isquémico mayor a 12 horas, y falleció un 33,3 % de los pacientes que no recibieron tratamiento trombolítico.Conclusiones: Predominaron el sexo masculino, las edades entre 65 y 74 años, y la hipertensión arterial. La mayoría recibió trombólisis, con tiempo dolor-puerta entre 3 y 6 horas, y puerta-aguja entre 30 y 60 minutos. La complicación que más se presentó durante la trombólisis fue la hipotensión arterial y la causa más frecuente de no realización del procedimiento fue el tiempo dolor-puerta mayor a 12 horas, donde predominaron los fallecimientos. La trombólisis oportuna sigue siendo la principal herramienta para elevar la supervivencia de los pacientes con infarto agudo de miocardio en hospitales sin intervencionismo coronario percutáneo.

    Full Text Available Embora a atenção ao idoso seja uma prioridade emergente no Brasil, pouca ênfase tem sido dada a modelos de organização de serviços hospitalares para pacientes geriátricos. São revisados modelos de serviços hospitalares para admissão e manuseio de casos agudos em idosos, com ênfase na discussão sobre o papel e o posicionamento da medicina geriátrica (incluindo sua interface com especialidades e com a clínica médica no âmbito da atenção hospitalar. Foi realizada pesquisa na base de dados Medline (1989-1999, bem como nos principais livros-texto de geriatria e de gerontologia, buscando identificar descrições de serviços hospitalares para cuidado agudo de pacientes idosos. As características dos modelos identificados foram compiladas e descritas à luz de sua adequação à realidade dos serviços de saúde no Brasil. Exemplos de intervenções em geriatria, com efetividade demonstrada através de revisões sistemáticas, foram também citadas. Os modelos mais freqüentemente relatados foram cuidado prolongado, tradicional, baseado na idade cronológica, não especializado e integrado. Adaptações e variantes de alguns desses modelos foram freqüentemente relatadas, assim como seu impacto potencial na efetividade do cuidado geriátrico. Evidências sobre o melhor modelo a seguir não foram identificadas, mas aqueles modelos favorecendo a integração da geriatria com a clínica geral pareceram mais adequados à nossa realidade. Ressalta a necessidade de reestruturação de serviços de saúde para responder às novas demandas que surgem com o envelhecimento da população, bem como do delineamento de serviços hospitalares para casos agudos, importantes para a efetividade do cuidado geriátrico e que devem ser objeto de maior debate e pesquisa no Brasil.

A las 48 horas presentó el cuadro clínico correspondiente a un glaucoma agudo y, que por no ceder al tratamiento medicamentoso, se le realizó iridectomía periférica con anestesia local. En el análisis de los antecedentes patológicos familiares relacionados con la intervención quirúrgica para apendicectomía y de los medicamentos utilizados, se llegó a la conclusión de que la existencia de historia familiar de glaucoma en esta paciente, unida a la maniobra de laringoscopia, al uso de succinilcolina y la atropina fueron factores que de forma individual o asociados contribuyeron al ataque de glaucoma agudo.The case of a female patient aged 56 who underwent laparotomy with general orotracheal anesthesia with thiopental, succinylcholine, halothane, nitric oxide and oxigen was reported. No immediate complications were observed. 48 hours later he presented the clinical picture corresponding to acute glaucoma. As she did not respond to drug treatment, peripheral iridectomy was performed with local anesthesia. In the analysis of the family pathological history related with appendectomy and with the drugs used, it was concluded that the existance of glaucoma family history in this patient together with the laryngoscopy maneuver, the use of succinylcholine and atropine were factors that in an individual or associated way contributed to the acute glaucoma attack.

    Full Text Available La presente investigación muestra los patrones geográficos de las hospitalizaciones por infarto agudo al miocardio en el seguro público de salud de Costa Rica en el trienio 2010-2012. Para el análisis geográfico por área de salud se utiliza un modelo bayesiano jerárquico espacial. Se estiman razones estandarizadas suavizadas y, como medida de precisión, la probabilidad de que cada área de salud registre un riesgo de hospitalización estadísticamente diferente al promedio nacional. En la determinación de presencia de autocorrelación espacial se utiliza el indicador de la I de Moran. La amplitud entre las variaciones observadas se estima mediante la razón interpercentil (percentil 95/percentil 5 y el coeficiente de variación. La tasa bruta de hospitalizaciones es de 5,8 por 10 mil habitantes en hombres y 2,6 / 10 mil en mujeres. Se registra un rango de variación de más de dos veces en las hospitalizaciones entre las áreas con mayores y menores egresos. Se presenta un patrón de bajas tasas de hospitalizaciones por infarto agudo al miocardio en áreas de salud fuera del Área Metropolitana, donde se encuentran los hospitales nacionales de mayor complejidad. Este elemento podría estar asociado a dificultades en el acceso de los servicios de hospitalización.

    Full Text Available Se realizó un estudio descriptivo transversal prospectivo, para determinar el comportamiento del intervalo QT corregido prolongado, en pacientes con síndrome coronario agudo sin elevación del segmento ST, en el Centro Diagnóstico Integral “Los Arales”, San Diego, año 2009. El universo fue de 48 pacientes y la muestra incluyó a 29 pacientes con ECG normal o sin nuevos cambios isquémicos. Al ingreso se determinaron los valores del intervalo QT corregido, las variables demográficas, antecedentes personales, niveles enzimáticos de CK-MB y el score TIMI. Estos resultados se correlacionaron con la aparición de eventos clínicos (muerte, infarto no fatal y revascularización un mes después del ingreso. De los 29 pacientes analizados sólo 11 (38% presentaron eventos clínicos, mientras que los restantes 18 (62% no los tuvieron. Los pacientes con eventos presentaron valores del iQTc más prolongados por encima del punto de corte. En ambos grupos predominó el sexo masculino y el grupo de edad más frecuente fue el de 60 a 69 años. El tabaquismo, la hipertensión y la hipercolesterolemia fueron los más prevalentes para ambos grupos, así como el uso previo de aspirina. La estratificación de riesgo TIMI y los parámetros basales en los pacientes estudiados fueron mayores y revelan un mayor porcentaje en el grupo con eventos clínicos. Los resultados demuestran que el iQTc predice eventos adversos cardiovasculares hasta 30 días después del ingreso.

    Full Text Available ResumenEl tromboembolismo pulmonar agudo tiene mayor morbilidad y mortalidad en los ancianos, pero puede presentarse en adultos jóvenes; por eso el diagnóstico certero es muy importante en este grupo etario. En este artículo se presenta el caso de un hombre de 37 años de edad, que acude al cuerpo de guardia por dolor precordial, sin alteraciones electrocardiográficas y dilatación de las cavidades derechas en el ecocardiograma. Se realizó AngioTC y se observó una dilatación del tronco de la arteria pulmonar, donde había una imagen hipodensa que ocupaba su porción distal, en relación con tromboembolismo pulmonar agudo. El paciente evolucionó favorablemente con el tratamiento. Mediante este estudio, se evidencia la importancia del AngioTC con tomógrafo de doble fuente, para la evaluación del dolor torácico agudo, en el paciente que no tiene manifestaciones electrocardiográficas, ni enzimáticas de infarto agudo de miocardio. / AbstractAcute pulmonary thromboembolism have increased morbidity and mortality in the elderly, but it can also occur in young adults, which is why an accurate diagnosis is very important in this age group. This article presents the case of a 37-year-old man, who comes to the emergency room for chest pain without electrocardiographic abnormalities and dilatation of the right chambers on echocardiography. CT angiography was performed and it showed a dilated pulmonary trunk, where there was a hypodense image occupying its distal portion, in relation to acute pulmonary thromboembolism. The patient responded favorably to treatment. Through this study, the importance of CT angiography with dual-source CT scanner for evaluation of acute chest pain, in patients with no electrocardiographic manifestations or enzymatic myocardial infarction is demonstrated.

    Type 2 diabetes is characterized by a high risk of micro- and macro-vascular complications. Cardiovascular diseases are the leading cause of death of diabetic patients. In this context, the search for molecules decreasing cardiovascular mortality makes sense. Until the EMPA-REG OUTCOME study published late 2015, showing a reduction of cardiovascular mortality of patients treated with empagliflozin, an SGLT2 inhibitor, there was no molecule known to decrease cardiovascular mortality. The purpose of this article is to review the various existing antidiabetic molecules and their impact (positive/neutral/negative) on cardiovascular mortality. PMID:27487675

Se caracteriza por síntomas de comienzo agudo y curso fluctuante con inatención, pensamiento desorganizado, y con distintos niveles de alteración de la conciencia.En la bibliografía consultada, el SCA como manifestación de un síndrome de abstinencia aguda nicotínica fue descripto en solo ocho casos. Presentamos el caso de un tabaquista grave que, internado por una reagudización de su enfermedad pulmonar obstructiva crónica (EPOC, presentó un cuadro de SCA al tercer día de abstinencia tabacal, cediendo los síntomas tras la administración de un parche de nicotina. Lo descripto sugiere que en pacientes internados que presentan SCA y agitación, con fuertes antecedentes de tabaquismo, un simple ensayo con un parche de nicotina puede ofrecer en pocas horas una notable respuesta terapéutica y a su vez un test confirmatorio. El reconocimiento del SCA como forma de presentación de la abstinencia nicotínica permitirá identificar casos habitualmente complejos en los que se podrá implementar una sencilla y eficaz alternativa terapéutica.Delirium or acute confusional state among hospitalized patients is a frequent and serious problem. It is characterized by acute onset symptoms, fluctuating course, impaired attention, unorganized thinking, and altered level of conciousness. Delirium, as a manifestation of acute nicotine withdrawal syndrome has been reported in the reviewed literature only in eight cases. We report the case of a heavy smoker admitted because of a reagudization of his chronic obstructive pulmonary disease. At the third day of nicotine abstinence, he developed delirium with a rapid improvement of his symptoms after treatment with a transdermal nicotine patch. This description suggests that in hospitalized heavy smokers who develop delirium with agitation, a simple trial with a nicotine patch can offer a dramatic

Sin embargo, estos indicadores han tenido sus variaciones en el Servicio Provincial de Cardiología de Sancti Spíritus.Objetivo: Determinar los factores clínicos-epidemiológicos relacionados con la evolución intrahospitalaria de los pacientes ingresados con este diagnóstico.Método: Se realizó una investigación observacional, descriptiva, retrospectiva en el Servicio de Cardiología del Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus durante el año 2011. La muestra estuvo conformada por los 363 pacientes que ingresaron con algunas de las formas clínicas agudas de cardiopatía isquémica. Se calculó la distribución de frecuencias según variables clínicas y epidemiológicas y se aplicaron pruebas de significación estadística (Chi cuadrado, Regresión logística, Exponencial de beta, que permitieron establecer relaciones con las distintas variables y la mortalidad.Resultados: Las complicaciones que se presentaron con mayor frecuencia fueron: disfunción ventricular izquierda aguda, arritmias ventriculares y angina postinfarto. Los infartos de topografía anterior, el antecedente de infarto previo, la hipertensión arterial y el hábito de fumar, fueron las variables más relacionadas con las complicaciones mecánicas y el infarto recidivante. La mayor sobreestadía estuvo motivada por la angina postinfarto, el reinfarto y el shock cardiogénico.Conclusiones: Existió una disminución de la mortalidad hospitalaria por síndrome coronario agudo en el año 2011 aunque hubo una elevada incidencia de complicaciones mecánicas y arrítmicas que motivaron una mayor estadía en el Servicio de Cardiología.

    Full Text Available ResumenIntroducción y objetivos: La angioplastia primaria restablece de manera rápida y mantenida la permeabilidad de la arteria coronaria responsable del infarto agudo de miocardio, disminuye significativamente la mortalidad, y mejora el pronóstico y la calidad de vida a largo plazo. El objetivo fue describir la evolución clínica de los pacientes con infarto agudo de miocardio tratados con angioplastia primaria. Método: Estudio descriptivo, longitudinal y prospectivo con 69 pacientes, recepcionados de 8:00 am a 4:00 pm, tratados con angioplastia primaria en el Instituto de Cardiología y Cirugía Cardiovascular, desde el 1 de julio de 2007 hasta el 31 de diciembre de 2008. Se realizó seguimiento clínico durante 180 días, donde se evaluó la frecuencia de sucesos clínicos mayores: muerte, reinfarto, angina postinfarto e inestable, necesidad de nueva revascularización y hemorragia mayor. Resultados: El tabaquismo y la hipertensión arterial tuvieron una prevalencia elevada. La localización inferior del infarto y la enfermedad de un vaso fueron las más frecuentes. Prevaleció el resultado inmediato exitoso. Los casos fallidos se relacionaron, con la coronaria derecha, el flujo TIMI 0 - 1 y el tiempo de evolución mayor de seis horas. Los sucesos clínicos mayores en el seguimiento fueron escasos y más frecuentes durante los primeros 30 días de seguimiento. Conclusiones: La angioplastia primaria realizada durante las primeras seis horas después del comienzo de los síntomas, es un procedimiento eficaz para tratar el infarto agudo de miocardio, debido al predominio del resultado exitoso y la escasa frecuencia de sucesos clínicos mayores durante seis meses de seguimiento clínico. / AbstractIntroduction and Objectives: Primary coronary angioplasty reestablishes fast and sustained way the permeability of acute myocardial infarction related artery.

    In the last years opioids have become of great importance in the relief of postoperative and other forms of acute pain. Reasons for this trend have been the availability of agonist opioids like phentanyl. sulphentanyl and alphentanyl and the results of research on the physlology. The pharmacology and the chemistry of drug receptors and neurotransmitters. The studies on chemicals other than opioids that contribute to pain relief when administered through different ways. specially the spinal. Have also influenced such a trend.

    En los últimos años los opiáceos han adquirido gran importancia en el alivio del dolor agudo especialmente del tipo postoperatorio. Una de las razones ha sido la disponibilidad de morfínicos agonistas como el fentanil, el sufentanil y el alfentanil; otra es la investigación de la fisiología, la farmacología y la química de los receptores y los neurotransmisores como de sustancias diferentes a los opláceos, aplicadas por diferentes vías en especial la espinal, que coadyuvan al alivio del dolor.

    International Nuclear Information System (INIS)

    The Morro Agudo Dyke Swarm consists of mafic and ultramafic dykes and ultramafic dykes and stocks that intrude Archean granite-gneiss terranes of the Goias Massif. The dyke swarm was subdivided into five rock groups: Group I-basaltic andesite in dykes; Group II-metadiabase, diabase, metagabbro and amphibolite in dykes: Group III-metadiabase associated with-meta ultramafic rocks in the same dyke; Group IV-meta ultramafic rocks in dykes; Group V-meta ultramafic rocks in stocks. Four basaltic andesite dyke samples were dated using the K-Ar whole-rock method, yielding 2,412 ± 30 Ma, 2,403 ± 48 Ma, 2,254 ± Ma and 2,006 ±45 Ma ages. A Sm-Nd isochronic diagram for Group III mafic-ultramafic dyke yielded a 2,331 ± 101 Ma age with 0.50976 initial ratio. It is believed that this age may be extensive to the other mafic-ultramafic dykes of the dyke swarm. (author)

    Full Text Available En los últimos años se han redoblado los esfuerzos para disminuir y en el mejor de los casos evitar el daño al músculo cardíaco durante el infarto agudo. Las drogas trombolíticas han contribuido positivamente al respecto. Sin embargo, nace la necesidad de buscar formas alternas de tratamiento que proporcionen un más rápido y efectivo restablecimiento de la circulación coronaria. Nos referimos a la Angioplastía Primaria como tratamiento inicial del infarto agudo. Presentamos los primeros 16 casos con infarto agudo al miocardio en curso, tratados con Angioplastía Primaria, 15 de 16 pacientes evolucionaron en forma satisfactoria, sin complicaciones intra-hospitalarias. Hubo una defunción más directamente relacionada a las complicaciones del infarto que al procedimiento de angioplastía per-se. De esta manera reafirmamos la utilidad de esta nueva forma de tratamiento, planteando una alternativa terapéutica adicional en beneficio de los pacientes que están sufriendo un infarto agudo al miocardio.In the last several years there have been increased efforts to reduce, and in the best of cases to avoid , damage to the cardiac muscle during acute myocardial infarction. Thrombolytic drugs have contributed favorably in that respect. However, there has been the need to find alternative methods of treatment to provide faster and more efective reestablishment of coronary circulation. In this paper we refer to primary coronary angioplasty as initial treatment for acute myocardial infarction. We present our first 16 patients with an evolving acute myocardial infarction treated with primary angioplasty, 15 of the 16 patients had a satisfactory course, without inhospital complications. There was one death more directly related to complications of the infarction rather than to the angioplasty procedure itself. In this way we reinforce the utility of this new method of treatment, making it an alternative therapeutic option in benefit of patients with

Sin embargo los sistemas más tradicionales resultan poco adecuados para la población anciana, en los que la incapacidad asociada a la enfermedad resulta determinante para explicar el consumo de recursos y los resultados asistenciales. Por ello, nos planteamos aplicar en servicios especializados de atención al anciano un sistema que contempla este parámetro, los Grupos de Utilización de Recursos (RUG, analizando las características y diferencias en la distribución en función de RUG en cuatro Servicios de Geriatría. Métodos: Se estudian transversalmente, mediante cortes sucesivos en períodos superiores a la estancia media en cada unidad, los pacientes ingresados en las unidades de agudos y media estancia de los Servicios de Geriatría del Hospital Monte Naranco (HMN (n=318, Hospital Central de la Cruz Roja (HCCR (n=384, Hospital General de Guadalajara (HG (n=272 y Hospital Virgen del Valle (HVV (n=390, en lo relativo a su distribución según la clasificación RUG-T18.

El objetivo de este estudio fue evaluar la incidencia de NIC y los factores asociados a su desarrollo en pacientes ingresados en unidad coronaria con requerimiento de cinecoronariografía (CCG. Se realizó un estudio de cohorte retrospectivo. Se incluyeron pacientes consecutivos cursando SCA estudiados con CCG dentro de las 72 horas de su admisión. Se definió NIC al aumento del 25% del valor de creatinina a las 48 h sobre el nivel basal de ingreso. El período de inclusión fue entre el 1° de enero de 2004 hasta el 30 de junio de 2010. Se analizaron 125 casos. La incidencia de NIC fue del 10.4% (n = 13. En el análisis multivariado, los factores asociados independientemente a su desarrollo fueron la edad [OR 1.05 (IC 95% 1.004 - 1.11 p = 0.034], la angioplastia a múltiple vaso [OR 2.2 (IC 95% 1.07 - 4.8, p = 0.03] y el volumen de contraste utilizado [OR 1.007 (IC 95% 1.001 - 1.01, p = 0.014].

    Full Text Available En la Argentina, una de cada tres muertes es de origen cardiovascular y el infarto agudo de miocardio (IAM es una de sus presentaciones más agresivas y frecuentes. Sin embargo, en nuestro país los datos epidemiológicos relacionados al infarto son escasos. Diversas encuestas y registros se han realizado en estos últimos 25 años por las diferentes sociedades científicas, las cuales, si bien aportan valiosa información, sólo representan a una parte de la población con posibilidades de acceso a centros de alta complejidad. Los datos proporcionados por estos registros evidencian un aumento progresivo en la tasa de reperfusión; sin embargo, esto no se tradujo en una reducción de la mortalidad. Esta revisión tiene como objetivo aportar toda la información disponible sobre el IAM en la Argentina, y busca identificar los recursos necesarios para lograr un adecuado manejo diagnóstico-terapéutico de esta enfermedad.In Argentina, one out of three deaths is of cardiovascular origin and acute myocardial infarction (AMI is one of the most aggressive and frequent. In our country epidemiological data related to infarction are scarce. Various surveys and reports have been carried out in the past 25 years by different scientific societies, which, even though they provide valuable information, enclose only a small range of the population with access to high complexity centers. Though these records show a gradual increase in the rate of reperfusion, this has not resulted in a mortality reduction. This review is committed to provide all available information about the AMI in Argentina, in order to provide the necessary resources to the right diagnosis and therapeutic handling of this disease.

    cholesterol might not cause cardiovascular disease as originally thought has now generated renewed interest in raised concentrations of triglycerides. This renewed interest has also been driven by epidemiological and genetic evidence supporting raised triglycerides, remnant cholesterol, or triglyceride......-rich lipoproteins as an additional cause of cardiovascular disease and all-cause mortality. Triglycerides can be measured in the non-fasting or fasting states, with concentrations of 2-10 mmol/L conferring increased risk of cardiovascular disease, and concentrations greater than 10 mmol/L conferring increased risk...... of acute pancreatitis and possibly cardiovascular disease. Although randomised trials showing cardiovascular benefit of triglyceride reduction are scarce, new triglyceride-lowering drugs are being developed, and large-scale trials have been initiated that will hopefully provide conclusive evidence...

    Full Text Available Al describir la ataxia de Friedreich, Nicholaus hizo referencia a la patología cardiaca. Esta enfermedad autosómica recesiva se debe a una mutación dinámica en el gen FRDA, codificándose deficientemente la proteína Frataxina, conduciendo a estrés oxidativo y muerte celular cardiaca. La presente investigación se desarrolló con el objetivo de describir las anomalías cardiovasculares presentes en los pacientes cubanos afectados por ataxia de Friedreich. A los individuos con diagnóstico molecular confirmatorio de la enfermedad se les realizó electrocardiograma y ecocardiograma, así como evaluación clínica mediante escalas validadas internacionalmente: ICARS y SARA. Los trastornos de repolarización ventricular difusos, los trastornos de conducción intraauricular, así como los trastornos de la función diastólica resultaron hallazgos frecuentes. El patrón restrictivo apreciado provee evidencia invivo de que la enfermedad conduce a disfunción diastólica del ventrículo izquierdo. La ocurrencia de un Infarto Agudo del Miocardio silente indica la importancia de identificar formas incipientes de afectación miocárdica.

    Although huge and long-lasting research efforts have been spent on the development of new diagnostic techniques investigating cardiovascular diseases, still fundamental challenges exist; the main challenge being the diagnosis of a suspected or known coronary artery disease or its consequences (myocardial infarction, heart failure etc.). Beside morphological techniques, functional imaging modalities are available in clinical diagnostic algorithms, whereas molecular cardiovascular imaging techniques are still under development. This review summarizes clinical-diagnostical challenges of modern cardiovascular medicine as well as the potential of new molecular imaging techniques to face these. (orig.)

    There is a wealth of evidence linking depression to increased risk for cardiovascular disease (CVD) and worse outcomes among patients with known CVD. In addition, there are safe and effective treatments for depression. Despite this, depression remains under-recognized and undertreated in patients at risk for or living with CVD. In this review, we first summarize the evidence linking depression to increased risk of CVD and worse patient outcomes. We then review the mechanisms by which depression may contribute to cardiovascular risk and poor cardiovascular outcomes. We then summarize prior studies of depression treatment on cardiovascular outcomes. Finally, we offer guidance in the identification and management of depression among CVD populations. Given that 1 in 4 CVD patients has concurrent depression, application of these best-practices will assist providers in achieving optimal outcomes for their CVD patients. PMID:25850976

    In this paper, a novel approach to modeling and diagnosing the cardiovascular system is introduced. A model exhibits a subset of the dynamics of the cardiovascular behavior of an individual by using a recurrent artificial neural network. Potentially, a model will be incorporated into a cardiovascular diagnostic system. This approach is unique in that each cardiovascular model is developed from physiological measurements of an individual. Any differences between the modeled variables and the variables of an individual at a given time are used for diagnosis. This approach also exploits sensor fusion to optimize the utilization of biomedical sensors. The advantage of sensor fusion has been demonstrated in applications including control and diagnostics of mechanical and chemical processes.

    Full Text Available Con muy diversas investigaciones se han demostrado los efectos agudos del ejercicio físico en los procesos cognitivos (memoria, inteligencia, tiempo de reacción, creatividad, etc. según la edad. Sin embargo, gran cantidad de variables se ven involucradas en los diferentes tratamientos. Es, por esto, que se pretendió realizar una investigación específica y homogénea, de manera que los cambios obtenidos en la inteligencia y la memoria en las diferentes edades se deban al tratamiento en sí, y no a la influencia de otros factores. Para esto, se aplicó un tratamiento que consistió en realizar ejercicio aeróbico subiendo y bajando una grada de 27 cm. de alto x 30 cm. de ancho, durante 10 minutos, a una intensidad del 60% de la frecuencia cardíaca máxima. Los sujetos fueron 100 hombres con edades entre la niñez y la edad avanzada. Se ubicaron en 5 subgrupos que realizaron un 'pretest', el tratamiento indicado y un 'postest'. Las pruebas fueron el test de Raven para la inteligencia y el Verbal Script Digit Span para medir la memoria auditiva. Para conocer los resultados se realizó un análisis de varianza Anova 5x2x2 para grupos independientes, utilizando los puntajes obtenidos en las diferencias entre 'pretest' y 'postest', para ambas variables, con su respectivo 'post-hoc' en los casos requeridos. Y para determinar la magnitud del cambio, se obtuvo los tamaños del efecto. Se encontró que con ejercicio aeróbico submaximal, la totalidad de los grupos etarios mejoraron sus resultados en el test de memoria con mejor resultado los de edades promedio de 25.5 y 63.25 años. Para la variable de inteligencia los sujetos de 34.75 y 52.4 años en promedio lograron los mejores resultados, mientras que los jóvenes de 25.5 años y los adultos mayores no tuvieron cambio significativo en este aspecto.

Lamortalidad intrahospitalaria del IAM en la actualidad es de aproximadamente el 10%, almenos en los centros que participan en registros.Su tratamiento está orientado a la reperfusión de la arteria ocluida con angioplastia primariao trombolíticos. Sin embargo, sólo un pequeño número de hospitales disponen deangioplastia primaria y reciben trombolíticos muchos menos pacientes que los que los requieren.Para lograr una reducción de la mortalidad se debe enfatizar la pronta y amplia utilizaciónde trombolíticos, anticoagulantes y antiagregantes.El logro de un impacto trascendente sobre la mortalidad del IAM requiere la formulación deun programa nacional dirigido por las autoridades sanitarias con el consenso de las sociedadescientíficas.Este programa debería concentrarse en al menos en tres puntos:1. Realización rápida e interpretación del electrocardiograma en todos los pacientes condolor torácico, que incluya la utilización de la emergencia prehospitalaria. Una central delectura con médicos expertos puede asistir a los centros de salud que carezcan de personalcapacitado.2. Reperfusión rápida con trombolíticos y/o angioplastia. En la elección del trombolíticodeben balancearse la sencillez de los trombolíticos en bolo y su mayor éxito fibrinolíticoversus el alto costo comparado con la estreptocinasa. El tema de facilitar su aplicación esmuy importante cuando se piensa en administrar trombolíticos en centros de baja complejidad.3. Estructuración de una red para derivar los casos más graves a centros de referencia enunidades equipadas y con personal entrenado. Es posible que el 50% de los IAM requieranderivación por insuficiencia cardíaca grave, fracaso de la trombólisis o isquemia recurrente.REV ARGENT CARDIOL 2010;78:259-263.

    Context Violence, experienced in either childhood or adulthood, has been associated with physical health outcomes including cardiovascular disease. However, the consistency of the existing literature has not been evaluated. Evidence acquisition In 2013, the authors conducted a PubMed and Web of Science review of peer reviewed articles published prior to August 2013 on the relation between violence exposure, experienced in either childhood or adulthood, and cardiovascular outcomes. To meet inclusion criteria, articles had to present estimates for the relation between violence exposure and cardiovascular outcomes (hypertension, blood pressure, stroke, coronary disease, or myocardial infarction) adjusted for demographic factors. Articles focusing on violence from TV, video games, natural disasters, terrorism, or war were excluded. Evidence synthesis The initial search yielded 2,273 articles; after removing duplicates and applying inclusion and exclusion criteria, 30 articles were selected for review. A consistent positive relation was noted on the association between violence experienced during childhood and cardiovascular outcomes in adulthood (i.e., hypertension, coronary heart disease, and myocardial infarction). Associations across genders with varying types of violence exposure were also noted. By contrast, findings were mixed on the relation between adult violence exposure and cardiovascular outcome. Conclusions Despite varying definitions of violence exposure and cardiovascular endpoints, a consistent relation exists between childhood violence exposure, largely assessed retrospectively, and cardiovascular endpoints. Findings are mixed for the adult violence–cardiovascular health relation. The cross-sectional nature of most adult studies and the reliance of self-reported outcomes can potentially be attributed to the lack of findings among adult violence exposure studies. PMID:25599905

    The first marathon run as an athletic event took place in the context of the Olympic Games in 1896 in Athens, Greece. Today, participation in a 'marathon run' has become a global phenomenon attracting young professional athletes as well as millions of mainly middle-aged amateur athletes worldwide each year. One of the main motives for these amateur marathon runners is the expectation that endurance exercise (EE) delivers profound beneficial health effects. However, with respect to the cardiovascular system, a controversial debate has emerged whether the marathon run itself is healthy or potentially harmful to the cardiovascular system, especially in middle-aged non-elite male amateur runners. In this cohort, exercise-induced increases in cardiac biomarkers-troponin and brain natriuretic peptide-and acute functional cardiac alterations have been observed and interpreted as potential cardiac damage. Furthermore, in the cohort of 40- to 65-year-old males engaged in intensive EE, a significant risk for the development of atrial fibrillation has been identified. Fortunately, recent studies demonstrated a normalization of the cardiac biomarkers and the functional alterations within a short time frame. Therefore, these alterations may be perceived as physiological myocardial reactions to the strenuous exercise and the term 'cardiac fatigue' has been coined. This interpretation is supported by a recent analysis of 10.9 million marathon runners demonstrating that there was no significantly increased overall risk of cardiac arrest during long-distance running races. In conclusion, intensive and long-lasting EE, e.g. running a full-distance Marathon, results in high cardiovascular strain whose clinical relevance especially for middle-aged and older athletes is unclear and remains a matter of controversy. Furthermore, there is a need for evidence-based recommendations with respect to medical screening and training strategies especially in male amateur runners over the age of

    Full Text Available Abstract Air pollution is increasingly recognized as an important and modifiable determinant of cardiovascular diseases in urban communities. The potential detrimental effects are both acute and chronic having a strong impact on morbidity and mortality. The acute exposure to pollutants has been linked to adverse cardiovascular events such as myocardial infarction, heart failure and life-threatening arrhythmias. The long-terms effects are related to the lifetime risk of death from cardiac causes. The WHO estimates that air pollution is responsible for 3 million premature deaths each year. The evidence supporting these data is very strong nonetheless, epidemiologic and observational data have the main limitation of imprecise measurements. Moreover, the lack of clinical experimental models makes it difficult to demonstrate the individual risk. The other limitation is related to the lack of a clear mechanism explaining the effects of pollution on cardiovascular mortality. In the present review we will explore the epidemiological, clinical and experimental evidence of the effects of ozone on cardiovascular diseases. The pathophysiologic consequences of air pollutant exposures have been extensively investigated in pulmonary systems, and it is clear that some of the major components of air pollution (e.g. ozone and particulate matter can initiate and exacerbate lung disease in humans 1. It is possible that pulmonary oxidant stress mediated by particulate matter and/or ozone (O3 exposure can result in downstream perturbations in the cardiovasculature, as the pulmonary and cardiovascular systems are intricately associated, and it is well documented that specific environmental toxins (such as tobacco smoke 2 introduced through the lungs can initiate and/or accelerate cardiovascular disease development. Indeed, several epidemiologic studies have proved that there is an association between PM and O3 and the increased incidence of cardiovascular morbidity

    Cardiovascular diseases are among the most frequent complications in pregnancies. Among them preexisting heart diseases including congenital heart disease, genetic cardiomyopathies, myocardial infarction and chemotherapy-induced cardiomyopathies display a special challenge for the mother and her physicians. Moreover, the incidence of cardiovascular disease induced by or associated with pregnancy, i.e. hypertensive disorders and peripartum cardiomyopathies, has increased over the past decades. In the present overview we explain why pregnancy is a stress model for the maternal heart and summarize the current knowledge on the influence of pregnancy on preexisting cardiomyopathies. We highlight recent advances in research with regard to hypertensive complications in pregnancy and peripartum cardiomyopathy (PPCM). Moreover, we summarize etiologies, risk factors, pathomechanisms, diagnosis, treatment, management and prognosis. Finally, interdisciplinarity between different clinical fields and basic science is a key requirement to avoid longterm damage to the cardiovascular system induced by pregnancy associated impacts and with this improve women's health in general.

    Cardiovascular tissue engineering offers the promise of biologically based repair of injured and damaged blood vessels, valves, and cardiac tissue. Major advances in cardiovascular tissue engineering over the past few years involve improved methods to promote the establishment and differentiation of induced pluripotent stem cells (iPSCs), scaffolds from decellularized tissue that may produce more highly differentiated tissues and advance clinical translation, improved methods to promote vascularization, and novel in vitro microphysiological systems to model normal and diseased tissue function. iPSC technology holds great promise, but robust methods are needed to further promote differentiation. Differentiation can be further enhanced with chemical, electrical, or mechanical stimuli. PMID:27303643

    Full Text Available Cardiovascular disease is the leading cause of death for both men and women worldwide. Much emphasis has been placed on the primary and secondary prevention of cardiovascular disease. While depression and anxiety increase the risk of developing cardiovascular disease, cardiovascular disease also increases the risk of developing anxiety and depression. Thus, promoting optimal mental health may be important for both primary and secondary prevention of cardiovascular disease. Like lowering blood pressure, lipids, and body weight, lowering anger and hostility and improving depression and anxiety may also be an important intervention in preventive cardiology. As we strive to further improve cardiovascular outcomes, the next bridge to cross may be one of offering patients nonpharmacologic means for combating daily mental stress and promoting mental health, such as yoga and pranayama. Indeed, the best preventive cardiovascular medicine may be a blend of both Western and Eastern medicine.

Foi realizada pesquisa na base de dados Medline (1989-1999, bem como nos principais livros-texto de geriatria e de gerontologia, buscando identificar descrições de serviços hospitalares para cuidado agudo de pacientes idosos. As características dos modelos identificados foram compiladas e descritas à luz de sua adequação à realidade dos serviços de saúde no Brasil. Exemplos de intervenções em geriatria, com efetividade demonstrada através de revisões sistemáticas, foram também citadas. Os modelos mais freqüentemente relatados foram cuidado prolongado, tradicional, baseado na idade cronológica, não especializado e integrado. Adaptações e variantes de alguns desses modelos foram freqüentemente relatadas, assim como seu impacto potencial na efetividade do cuidado geriátrico. Evidências sobre o melhor modelo a seguir não foram identificadas, mas aqueles modelos favorecendo a integração da geriatria com a clínica geral pareceram mais adequados à nossa realidade. Ressalta a necessidade de reestruturação de serviços de saúde para responder às novas demandas que surgem com o envelhecimento da população, bem como do delineamento de serviços hospitalares para casos agudos, importantes para a efetividade do cuidado geriátrico e que devem ser objeto de maior debate e pesquisa no Brasil.Although the implementation of geriatric services is an emerging priority in Brazil, little emphasis has been put on the type of acute care that should be provided for elderly

    Full Text Available Prodrugs are biologically inactive derivatives of an active drug intended to solve certain problems of the parent drug such as toxicity, instability, minimal solubility and non-targeting capabilities. The majority of drugs for cardiovascular diseases undergo firstpass metabolism, resulting in drug inactivation and generation of toxic metabolites, which makes them appealing targets for prodrug design. Since prodrugs undergo a chemical reaction to form the parent drug once inside the body, this makes them very effective in controlling the release of a variety of compounds to the targeted site. This review will provide the reader with an insight on the latest developments of prodrugs that are available for treating a variety of cardiovascular diseases. In addition, we will focus on several drug delivery methodologies that have merged with the prodrug approach to provide enhanced target specificity and controlled drug release with minimal side effects.

  18. Cardiovascular and interventional radiology

    International Nuclear Information System (INIS)

    This year's cardiovascular section demonstrates a continued growth in the number of digests on cardivascular and general interventional topics and continued progress in MRI studies. The reader will also notice fewer digests on DSA and percutaneous stone removal compared with the 1985 and 1986 Year Books. While newer technology, such as extracorporeal shock wave lithotripsy, has significantly reduced the number of percutaneous procedures for renal calculi, other interventional procedures, such as those involving fibrinolysis, are increasing by leaps and bounds. A number of digests on benign and malignant bile duct strictures continue to shed light on the management of these difficult cases. While abscess drainage is growing and well accepted by most surgeons, articles on esophageal dilatations seem to be declining in the radiology literature, probably on the basis of fewer operations being performed by us and more being performed by endoscopists. Digests on MRI in the cardiovascular system continue to report excellent images of the aorta and of congenital heart disease

  19. Cardiovascular: radioisotopic angiocardiography

    International Nuclear Information System (INIS)

    Radioisotopic angiocardiography, performed after the intravenous injection of 99/sup m/Tc-labeled pertechnetate or albumin, is a simple, rapid, and safe procedure which permits identification and physiologic assessment of a wide variety of congenital and acquired cardiovascular lesions in infants and children. These include atrial and ventricular septal defect, tetralogy of Fallot, pulmonic stenosis, aortopulmonary window, transposition of the great vessels, valvular stenosis and/or insufficiency, myocardial lesions, and lesions of the great vessels. The simplicity of the procedure lends itself to repeated measurements to assess the effects of therapy or to follow the course of the disease. A wide spectrum of congenital and acquired cardiovascular diseases have been studied which have particular application to the pediatric age group. (auth)

    Full Text Available Fundamento. Identificar factores asociados a la demora prehospitalaria en personas que han tenido un síndrome coronario agudo Material y métodos. Se estudiaron mediante encuesta pacientes ingresados por síndrome coronario agudo en los 33 hospitales públicos andaluces, obteniéndose información sobre diferentes tipos de variables: socio-demográficas, contextuales, clínicas, percepción, actuaciones, y transporte. Se aplicaron modelos de regresión logística multivariante para calcular las odds ratio para la demora. Resultados. De los 1.416 pacientes en total, más de la mitad tuvieron una demora superior a la hora. Se asocia a la distancia al hospital y al medio de transporte: cuando el evento ocurre en la misma ciudad del hospital, utilizar medios propios aumenta la demora, odds ratio= 1,51 (1,02-2,23; si la distancia es entre 1-25 kilómetros, no hay una diferencia entre medios propios y ambulancia, odds ratio = 1,41 y odds ratio = 1,43 respectivamente; y cuando supera los 25 kilómetros la ambulancia implica mayor demora, odds ratio = 3,13 y odds ratio = 2,20 respectivamente. Además, la sintomatología típica reduce la demora entre los hombres, pero la aumenta entre las mujeres. Asimismo, no darle importancia, esperar a la resolución de los síntomas, buscar atención sanitaria diferente a urgencias hospitalarias o al 061, tener antecedentes, encontrarse fuera de la vivienda habitual, y tener ingresos menores de 1.500 euros aumentan la demora. Tener síntomas respiratorios la reduce. Conclusiones. La demora prehospitalaria no se ajusta a las recomendaciones sanitarias, asociándose al entorno físico y social, a factores clínicos, y de percepción y actitudinales de los sujetos.

    Full Text Available A síndrome do desconforto respiratório agudo é caracterizada por uma reação inflamatória difusa do parênquima pulmonar, podendo ser induzida por um insulto direto ao epitélio alveolar (síndrome do desconforto respiratório agudo pulmonar ou indireto através do endotélio vascular (síndrome do desconforto respiratório agudo extrapulmonar. Acredita-se que uma terapia eficaz para o tratamento da síndrome do desconforto respiratório agudo deva atenuar a resposta inflamatória e promover adequado reparo da lesão pulmonar. O presente artigo apresenta uma breve revisão acerca do potencial terapêutico das células-tronco na síndrome do desconforto respiratório agudo. Essa revisão bibliográfica baseou-se em uma pesquisa sistemática de artigos experimentais e clínicos sobre terapia celular na síndrome do desconforto respiratório agudo incluídos nas bases de dados MedLine e SciELO nos últimos 10 anos. O transplante de células-tronco promove melhora da lesão inflamatória pulmonar e do conseqüente processo fibrótico, induzindo adequado reparo tecidual. Dentre os mecanismos envolvidos, podemos citar: diferenciação em células do epitélio alveolar e redução na liberação de mediadores inflamatórios e sistêmicos e fatores de crescimento. A terapia com células-tronco derivadas da medula óssea pode vir a ser uma opção eficaz e segura no tratamento da síndrome do desconforto respiratório agudo por acelerar o processo de reparo e atenuar a resposta inflamatória. Entretanto, os mecanismos relacionados à atividade antiinflamatória e antifibrogênica de tais células necessitam ser mais bem elucidados, limitando, assim, o seu uso clínico imediato.Acute respiratory distress syndrome is characterized by an acute pulmonary inflammatory process induced by the presence of a direct (pulmonary insult that affects lung parenchyma, or an indirect (extrapulmonary insult that results from an acute systemic inflammatory response

    2015-12-01

    Patients with rheumatoid arthritis (RA) and other inflammatory joint diseases (IJDs) have an increased risk of premature death compared with the general population, mainly because of the risk of cardiovascular disease, which is similar in patients with RA and in those with diabetes mellitus. Pathogenic mechanisms and clinical expression of cardiovascular comorbidities vary greatly between different rheumatic diseases, but atherosclerosis seems to be associated with all IJDs. Traditional risk factors such as age, gender, dyslipidaemia, hypertension, smoking, obesity and diabetes mellitus, together with inflammation, are the main contributors to the increased cardiovascular risk in patients with IJDs. Although cardiovascular risk assessment should be part of routine care in such patients, no disease-specific models are currently available for this purpose. The main pillars of cardiovascular risk reduction are pharmacological and nonpharmacological management of cardiovascular risk factors, as well as tight control of disease activity. PMID:26282082

    Hyperuricemia, gout as well as arterial hypertension and metabolic syndrom are highly prevalent and clinicians are frequently confronted with both conditions in the same patient. Hyperuricemia and gout are associated with cardiovascular comorbidities and a high cardiovascular risk. Despite coherent pathophysiological concepts, it remains to be determined, if this association is independent and causal. In daily clinical practice, cardiovascular risk factors should be thoroughly identified and consequently treated in all patients with hyperuricemia and gout. If preventive treatment of asymptomatic hyperuricemia with urate-lowering agents may improve cardiovascular risk and outcomes remains to be determined and is recommended only in special situations like young patients with severe hyperuricemia.

    Full Text Available The increased incidence of cardiovascular diseases (CVDs has stimulated research for substances that could improve cardiovascular health. Among them, resveratrol (RES, a polyphenolic compound notably present in grapes and red wine, has been involved in the “French paradox”. RES is known for its antioxidant and anti-inflammatory properties and for its ability to upregulate endothelial NO synthase (eNOS. RES was able to scavenge •OH/O2•− and peroxyl radicals, which can limit the lipid peroxidation processes. Moreover, in bovine aortic endothelial cells (BAEC under glucose-induced oxidative stress, RES restored the activity of dimethylargininedimethylaminohydrolase (DDAH, an enzyme that degrades an endogenous inhibitor of eNOS named asymmetric dimethylarginine (ADMA. Thus, RES could improve •NO availability and decrease the endothelial dysfunction observed in diabetes. Preclinical studies have made it possible to identify molecular targets (SIRT-1, AMPK, Nrf2, NFκB…; however, there are limited human clinical trials, and difficulties in the interpretation of results arise from the use of high-dose RES supplements in research studies, whereas low RES concentrations are present in red wine. The discussions on potential beneficial effects of RES in CVDs (atherosclerosis, hypertension, stroke, myocardial infarction, heart failure should compare the results of preclinical studies with those of clinical trials.

Os procedimentos metodológicos utilizados foram a revisão bibliográfica, pesquisa documental e um estudo de caso, realizado no município de Agudo, Rio Grande do Sul. No estudo de caso, procurou-se obter dados quantitativos e qualitativos, por meio de questionários e entrevistas abertas, dirigidos para 27 agricultores familiares fumicultores, com filhos com menos de 18 anos de idade. Os resultados da pesquisa indicam a existência de um confronto entre diferentes concepções sobre o trabalho da criança no âmbito da agricultura familiar. Os dispositivos legais, os termos de compromissos e os contratos de integração na cadeia produtiva do fumo proíbem o trabalho de menores de 18 anos, fundamentando-se nos princípios internacionais da garantia do pleno desenvolvimento das crianças. Na perspectiva das famílias, o trabalho das crianças é entendido como "ajuda", forma de socialização e formação dos herdeiros.

  18. Assessment of cardiovascular risk.

    2010-10-01

    Atherosclerotic cardiovascular disease (CVD) is the most common cause of death worldwide. Usually atherosclerosis is caused by the combined effects of multiple risk factors. For this reason, most guidelines on the prevention of CVD stress the assessment of total CVD risk. The most intensive risk factor modification can then be directed towards the individuals who will derive the greatest benefit. To assist the clinician in calculating the effects of these multiple interacting risk factors, a number of risk estimation systems have been developed. This review address several issues regarding total CVD risk assessment: Why should total CVD risk be assessed? What risk estimation systems are available? How well do these systems estimate risk? What are the advantages and disadvantages of the current systems? What are the current limitations of risk estimation systems and how can they be resolved? What new developments have occurred in CVD risk estimation?

    Full Text Available Edoardo Mannucci,1 Stefano Giannini,2 Ilaria Dicembrini1 1Diabetes Agency, Careggi Teaching Hospital, Florence, 2Section of Endocrinology, Department of Biomedical Clinical and Experimental Sciences, University of Florence and Careggi University Hospital, Florence, Italy Abstract: Basal insulin is an important component of treatment for both type 1 and type 2 diabetes. One of the principal aims of treatment in patients with diabetes is the prevention of diabetic complications, including cardiovascular disease. There is some evidence, although controversial, that attainment of good glycemic control reduces long-term cardiovascular risk in both type 1 and type 2 diabetes. The aim of this review is to provide an overview of the potential cardiovascular safety of the different available preparations of basal insulin. Current basal insulin (neutral protamine Hagedorn [NPH], or isophane and basal insulin analogs (glargine, detemir, and the more recent degludec differ essentially by various measures of pharmacokinetic and pharmacodynamic effects in the bloodstream, presence and persistence of peak action, and within-subject variability in the glucose-lowering response. The currently available data show that basal insulin analogs have a lower risk of hypoglycemia than NPH human insulin, in both type 1 and type 2 diabetes, then excluding additional harmful effects on the cardiovascular system mediated by activation of the adrenergic system. Given that no biological rationale for a possible difference in cardiovascular effect of basal insulins has been proposed so far, available meta-analyses of publicly disclosed randomized controlled trials do not show any signal of increased risk of major cardiovascular events between the different basal insulin analogs. However, the number of available cardiovascular events in these trials is very small, preventing any clear-cut conclusion.

Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction.

    Full Text Available BACKGROUND: The average lifespan of humans is increasing, and with it the percentage of people entering the 65 and older age group is growing rapidly and will continue to do so in the next 20 years. Within this age group, cardiovascular disease will remain the leading cause of death, and the cost associated with treatment will continue to increase. Aging is an inevitable part of life and unfortunately poses the largest risk factor for cardiovascular disease. CONTENT: We provide an overview of some of the molecular mechanisms involved in regulating lifespan and health, including mitochondria, telomeres, stem cells, sirtuins, Adenosine Monophosphate-activated Protein Kinase, Mammalian Target of Rapamycin and Insulin-like Growth Factor 1. We also provide future perspectives of lifespan and health, which are intimately linked fields. SUMMARY: Aging remains the biggest non-modifiable risk factor for cardiovascular disease. The biological, structural and mechanical changes in senescent cardiovascular system are thought to contribute in increasing incidence of cardiovascular disease in aging. Understanding the mechanisms contributing to such changes is therefore crucial for both prevention and development of treatment for cardiovascular diseases. KEYWORDS: cardiovascular aging, mitochondria, telomeres, sirtuin, stem cells.

    The practice of contrast-enhanced magnetic resonance angiography (CEMRA) has changed significantly in the span of a decade. Concerns regarding gadolinium (Gd)-associated nephrogenic systemic fibrosis in those with severely impaired renal function spurred developments in low-dose CEMRA and non-contrast MRA as well as efforts to seek alternative MR contrast agents. Originally developed for MR imaging use, ferumoxytol (an ultra-small superparamagnetic iron oxide nanoparticle), is currently approved by the US Food and Drug Administration for the treatment of iron deficiency anaemia in adults with renal disease. Since its clinical availability in 2009, there has been rising interest in the scientific and clinical use of ferumoxytol as an MR contrast agent. The unique physicochemical and pharmacokinetic properties of ferumoxytol, including its long intravascular half-life and high r1 relaxivity, support a spectrum of MRI applications beyond the scope of Gd-based contrast agents. Moreover, whereas Gd is not found in biological systems, iron is essential for normal metabolism, and nutritional iron deficiency poses major public health challenges worldwide. Once the carbohydrate shell of ferumoxytol is degraded, the elemental iron at its core is incorporated into the reticuloendothelial system. These considerations position ferumoxytol as a potential game changer in the field of CEMRA and MRI. In this paper, we aim to summarise our experience with the cardiovascular applications of ferumoxytol and provide a brief synopsis of ongoing investigations on ferumoxytol-enhanced MR applications.

Myocardial perfusion imaging is an invaluable tool for the demonstration of transient ischemia and infarction in heart and identification of viable and non-viable myocardial tissue. Thallium chloride (Tl-201) is the agent currently in wide use but its drawbacks have been well recognised. Hence tremendous amount of research work has been carried out to develop a suitable Tc-99m radiopharmaceutical for this purpose which has resulted in the introduction of two Tc-99m labelled radiopharmaceuticals HEXAMIBI and BATO. These are being tried as myocardial imaging agents these days and the choice amongst these depends on concrete clinical situation. The experimental work involving the synthesis of ligand MIBI, formulation into freeze dried KIT form, quality control procedure, biodistribution studies and finally clinical evaluation of locally produced KIT in human volunteers has now been reported here. Our KIT has been produced for the first time in Pakistan and has been tried on forty five patients in Nuclear Medical Centre, AFIP (Rawalpindi). The results obtained are comparable to those of Ti-201 with a slightly higher liver background in case of MIBI but because of the easy availability MIBI has become agent of choice for myocardial perfusion studies.

    The effects of space flight on the cardiovascular system have been studied since the first manned flights. In several instances, the results from these investigations have directly contradicted the predictions based on established models. Results suggest associations between space flight's effects on other organ systems and those on the cardiovascular system. Such findings provide new insights into normal human physiology. They must also be considered when planning for the safety and efficiency of space flight crewmembers.

    In the United States, $2.5 trillion is spent on healthcare annually. Seven chronic diseases account for half of all this expense. Of these 7, cardiovascular disease, hypertension, stroke, and diabetes mellitus are largely preventable. Integrative cardiology programs that focus on risk-factor modification through lifestyle change combined with early detection and advanced lipid management offer a new paradigm to the prevention of cardiovascular disease.

  20. Cardiovascular effects of basal insulins.

    2015-01-01

    Basal insulin is an important component of treatment for both type 1 and type 2 diabetes. One of the principal aims of treatment in patients with diabetes is the prevention of diabetic complications, including cardiovascular disease. There is some evidence, although controversial, that attainment of good glycemic control reduces long-term cardiovascular risk in both type 1 and type 2 diabetes. The aim of this review is to provide an overview of the potential cardiovascular safety of the different available preparations of basal insulin. Current basal insulin (neutral protamine Hagedorn [NPH], or isophane) and basal insulin analogs (glargine, detemir, and the more recent degludec) differ essentially by various measures of pharmacokinetic and pharmacodynamic effects in the bloodstream, presence and persistence of peak action, and within-subject variability in the glucose-lowering response. The currently available data show that basal insulin analogs have a lower risk of hypoglycemia than NPH human insulin, in both type 1 and type 2 diabetes, then excluding additional harmful effects on the cardiovascular system mediated by activation of the adrenergic system. Given that no biological rationale for a possible difference in cardiovascular effect of basal insulins has been proposed so far, available meta-analyses of publicly disclosed randomized controlled trials do not show any signal of increased risk of major cardiovascular events between the different basal insulin analogs. However, the number of available cardiovascular events in these trials is very small, preventing any clear-cut conclusion. The results of an ongoing clinical trial comparing glargine and degludec with regard to cardiovascular safety will provide definitive evidence. PMID:26203281

    Estrogen has pleiotropic effects on the cardiovascular system. The mechanisms by which estrogen confers these pleiotropic effects on cardiovascular function is under active investigation. Until a decade ago, all estrogen signaling was thought to occur by estrogen binding to nuclear estrogen receptors (ERα and ERβ), which bind to DNA and function as ligand activated transcription factors. Estrogen binding to the receptor alters gene expression thereby altering cell function. In 2000 estrogen w...

    The prevalence of obesity has increased worldwide over the past few decades. In 2013, the prevalence of obesity exceeded the 50% of the adult population in some countries from Oceania, North Africa, and Middle East. Lower but still alarmingly high prevalence was observed in North America (≈30%) and in Western Europe (≈20%). These figures are of serious concern because of the strong link between obesity and disease. In the present review, we summarize the current evidence on the relationship of obesity with cardiovascular disease (CVD), discussing how both the degree and the duration of obesity affect CVD. Although in the general population, obesity and, especially, severe obesity are consistently and strongly related with higher risk of CVD incidence and mortality, the one-size-fits-all approach should not be used with obesity. There are relevant factors largely affecting the CVD prognosis of obese individuals. In this context, we thoroughly discuss important concepts such as the fat-but-fit paradigm, the metabolically healthy but obese (MHO) phenotype and the obesity paradox in patients with CVD. About the MHO phenotype and its CVD prognosis, available data have provided mixed findings, what could be partially because of the adjustment or not for key confounders such as cardiorespiratory fitness, and to the lack of consensus on the MHO definition. In the present review, we propose a scientifically based harmonized definition of MHO, which will hopefully contribute to more comparable data in the future and a better understanding on the MHO subgroup and its CVD prognosis.

    Full Text Available Background: cardiovascular hyperreactivity in young people has been associated with different risk factors and a family history of hypertension. Objective: to determine the association between a family history of hypertension and cardiovascular risk factors with cardiovascular hyperreactivity. Method: a correlational, cross-sectional study was conducted in a universe of 77 young individuals aged 18 to 40 years from the Churuguara parish of the Falcon State in Venezuela. The variables were: age, sex, skin color, family history of hypertension, medical history of hypertension, diabetes mellitus, alcohol consumption, salt intake, physical activity and body mass index. The diastolic and systolic blood pressure before and after the pressor response elicited by an isometric exercise were determined as hemodynamic variables. Results: thirteen percent of the participants developed vascular reactivity after the hand-held weight test. Cardiovascular hyperreactivity is three times higher in individuals with a family history of hypertension. Sixty percent of those with a body mass index greater than or equal to 27 kg/m2 are hyperreactive. There is a higher cardiovascular response to the hand-held weight test as the consumption of alcohol increases. Thirty three point three percent of the participants who smoke are hyperreactive. Conclusions: there is a significant association between a family history of hypertension, obesity, salt intake, alcohol consumption and vascular hyperreactivity.

    Full Text Available Vitamin D deficiency, as well as cardiovascular diseases (CVD and related risk factors are highly prevalent worldwide and frequently co-occur. Vitamin D has long been known to be an essential part of bone metabolism, although recent evidence suggests that vitamin D plays a key role in the pathophysiology of other diseases, including CVD, as well. In this review, we aim to summarize the most recent data on the involvement of vitamin D deficiency in the development of major cardiovascular risk factors: hypertension, obesity and dyslipidemia, type 2 diabetes, chronic kidney disease and endothelial dysfunction. In addition, we outline the most recent observational, as well as interventional data on the influence of vitamin D on CVD. Since it is still an unresolved issue whether vitamin D deficiency is causally involved in the pathogenesis of CVD, data from randomized controlled trials (RCTs designed to assess the impact of vitamin D supplementation on cardiovascular outcomes are awaited with anticipation. At present, we can only conclude that vitamin D deficiency is an independent cardiovascular risk factor, but whether vitamin D supplementation can significantly improve cardiovascular outcomes is still largely unknown.

    The mammalian circulatory system comprises both the cardiovascular system and the lymphatic system. In contrast to the blood vascular circulation, the lymphatic system forms a unidirectional transit pathway from the extracellular space to the venous system. It actively regulates tissue fluid homeostasis, absorption of gastrointestinal lipids, and trafficking of antigen-presenting cells and lymphocytes to lymphoid organs and on to the systemic circulation. The cardinal manifestation of lymphatic malfunction is lymphedema. Recent research has implicated the lymphatic system in the pathogenesis of cardiovascular diseases including obesity and metabolic disease, dyslipidemia, inflammation, atherosclerosis, hypertension, and myocardial infarction. Here, we review the most recent advances in the field of lymphatic vascular biology, with a focus on cardiovascular disease. PMID:26846644

    It was apparent that the bed-rest and spaceflight data indicated that decreases in plasma volume and cardiac atrophy along with cardiac remodeling were fundamental changes which predisposed many astronauts to post flight orthostatic intolerance. Despite the recently acquired in-flight and post-flight muscle sympathetic nerve activity findings suggesting that the sympathetic nerve responses were appropriate there remains significant contrary data from bed-rest studies, post- flight stand tests and hind-limb unweighted rat studies that suggest that the vasoconstrictive responses were compromised at least insufficient in susceptible individuals. The key issues raised is whether a diminished increase in sympathetic activity from baseline without changes in 254 First Biennial Space Biomedical Investigators'Workshop Cardiovascular peak response or receptor adaptations is an abnormal response or is an individual variance of response to the accentuated decrease in stroke volume. Data relating autonomic neural control of heart rate were presented to suggest that the vagal and sympathetic control of heart rate was attenuated. Also, bed-rest and space flight induced attenuated baroreflex control of heart rate was shown to be restored to pre-bedrest function by one bout of maximal dynamic exercise. However, these data were confounded by relying on the use of R-R interval as a measure of efferent responses of the baroreflex during a condition in which the baseline heart rate was changed. Clearly the idea that the autonomic control of heart rate may be changed by microgravity needs further investigation. This direction is suggested despite the fact that in the triple product (HR x SV x TPR = MAP) assessment of the regulation of arterial blood pressure during orthostasis the role of the HR reflex may be less influential than that associated. with cardiac atrophy (SV changes) and aberrant sympathetic vasoconstriction (resistance) changes.

    2012-03-01

    The predominant pattern of cardiovascular diseases in sub-Saharan Africa is that of poverty-related conditions (rheumatic heart valve disease, untreated congenital heart disease, tuberculous pericarditis) and diseases of unclear aetiology with a higher prevalence in this part of the world (peripartum cardiomyopathy, endomyocardial fibrosis). However, the prevalence of the traditional risk factors for cardiovascular diseases such as hypertension and marked obesity is high in a number of sub-Saharan settings, although they vary considerably among countries, urban/rural locations and specific subpopulations. In urban settings, hypertensive heart disease with systolic and diastolic function contributes substantially to morbidity. Awareness of the general public and health workers about the burden of cardiovascular diseases in women must be increased, and risk factor control programmes must be included in the health research agenda on the African continent. Improvement in health services with coordination of maternal health services and non-communicable diseases is also needed. This review focuses on the current knowledge of cardiovascular healthcare of women in sub-Saharan Africa, particularly their propensity for various forms of heart disease, access to healthcare, treatment received within the respective healthcare system, response to therapy and mortality. It highlights the gaps in knowledge and the paucity of data in most of these aspects. PMID:22350029

  19. Cardiovascular calcification. An inflammatory disease

    International Nuclear Information System (INIS)

    Cardiovascular calcification is an independent risk factor for cardiovascular morbidity and mortality. This disease of dysregulated metabolism is no longer viewed as a passive degenerative disease, but instead as an active process triggered by pro-inflammatory cues. Furthermore, a positive feedback loop of calcification and inflammation is hypothesized to drive disease progression in arterial calcification. Both calcific aortic valve disease and atherosclerotic arterial calcification may possess similar underlying mechanisms. Early histopathological studies first highlighted the contribution of inflammation to cardiovascular calcification by demonstrating the accumulation of macrophages and T lymphocytes in 'early' lesions within the aortic valves and arteries. A series of in vitro work followed, which gave a mechanistic insight into the stimulation of smooth muscle cells to undergo osteogenic differentiation and mineralization. The emergence of novel technology, in the form of animal models and more recently molecular imaging, has enabled accelerated progression of this field, by providing strong evidence regarding the concept of this disorder as an inflammatory disease. Although there are still gaps in our knowledge of the mechanisms behind this disorder, this review discusses the various studies that have helped form the concept of the inflammation-dependent cardiovascular calcification paradigm.

    Full Text Available As men grow older, testosterone (T levels decline and the significance of this change is debated. The evidence supporting a causal role for lower circulating T, or its metabolites dihydrotestosterone (DHT and estradiol, in the genesis of atherosclerosis and cardiovascular disease (CVD in men is limited. Observational studies associate low baseline T levels with carotid atherosclerosis, aortic and peripheral vascular disease, and with the incidence of cardiovascular events and mortality. Studies using mass spectrometry suggest that when total T is assayed optimally, calculation of free T might not necessarily improve risk stratification. There is limited evidence to support an association of estradiol with CVD. Interventional studies of T therapy in men with coronary artery disease have shown beneficial effects on exercise-induced myocardial ischemia. However, placebo-controlled, randomized clinical trials (RCTs of T therapy in men with the prespecified outcomes of cardiovascular events or deaths are lacking. Meta-analyses of randomized controlled trials of T published up to 2010 found no increase in cardiovascular events, mortality, or prostate cancer with therapy. Recently, in a trial of older men with mobility limitations, men randomized to receive a substantial dose of T reported cardiovascular adverse effects. This phenomenon was not reported from a comparable trial where men received a more conservative dose of T, suggesting a prudent approach should be adopted when considering therapy in frail older men with existing CVD. Adequately powered RCTs of T in middle-aged and older men are needed to clarify whether or not hormonal intervention would reduce the incidence of CVD.

  7. Cardiovascular adverse effects of phenytoin.

    Phenytoin is an established drug in the treatment of acute repetitive seizures and status epilepticus. One of its main advantages over benzodiazepines is the less sedative effect. However, the possibility of cardiovascular adverse effects with the intravenous use of phenytoin cause a reluctance to its usage, and this has lead to a search for safer anticonvulsant drugs. In this study, we aimed to review the studies which evaluated the safety of phenytoin with respect to cardiovascular adverse effects. The original clinical trials and case reports listed in PUBMED in English language between the years of 1946-2014 were evaluated. As the key words, "phenytoin, diphenylhydantoin, epilepsy, seizure, cardiac toxicity, asystole, arrhythmia, respiratory arrest, hypotension, death" were used. Thirty-two clinical trials and ten case reports were identified. In the case reports, a rapid infusion rate (>50 mg/min) of phenytoin appeared as the major cause of increased mortality. In contrast, no serious cardiovascular adverse effects leading to death were met in the clinical trials which applied the recommended infusion rate and dosages. An infusion rate of 50 mg/min was reported to be safe for young patients. For old patients and patients with a cardiovascular co-morbidity, a slower infusion rate was recommended with a careful follow-up of heart rhythm and blood pressure. No cardiovascular adverse effect was reported in oral phenytoin overdoses except one case with a very high serum phenytoin level and hypoalbuminemia. Phenytoin is an effective and well tolerated drug in the treatment of epilepsy. Intravenous phenytoin is safe when given at recommended infusion rates and doses. PMID:26645393

    Full Text Available A síndrome pulmonar e cardiovascular por hantavírus é uma doença de conhecimento relativamente recente e freqüentemente fatal, apresentando-se como síndrome do desconforto respiratório agudo. No Brasil, desde o primeiro surto, relatado em novembro/dezembro de 1993, em Juquitiba, 226 casos já foram registrados pela Fundação Nacional da Saúde. A doença afeta indivíduos previamente hígidos, apresentando-se com pródromo febril e sintomas semelhantes aos de um resfriado comum, podendo rapidamente evoluir para edema pulmonar, insuficiência respiratória aguda e choque. A hemoconcentração e a plaquetopenia são comuns da síndrome pulmonar e cardiovascular por hantavírus, e o quadro radiológico típico é de um infiltrado intersticial bilateral difuso, que progride rapidamente para consolidações alveolares, paralelamente à piora do quadro clínico. A mortalidade inicial era em torno de 75% e declinou para aproximadamente 35%, nos últimos anos. Os pacientes que sobrevivem geralmente recuperam-se completamente, cerca de uma semana após o estabelecimento do quadro respiratório. O agente causal, não reconhecido até há pouco, foi identificado como um hantavírus, cujo reservatório natural são animais roedores da família Muridae, subfamília Sigmodontinae. O tratamento específico antiviral ainda não é bem estabelecido, estando em estudo a eficácia de ribavirina. Cuidados de terapia intensiva como ventilação mecânica e monitoramento hemodinâmico invasivo são necessários nas formas mais graves da doença. Essas medidas, se instituídas precocemente, podem melhorar o prognóstico e a sobrevida dos pacientes com síndrome pulmonar e cardiovascular por hantavírus.

    Full Text Available Background: there are no studies that confirm the association between cardiovascular hyperreactivity and the risk of cardiovascular morbidity. Objective: to determine the association between cardiovascular hyperreactivity and the risk of cardiovascular morbidity in normotensive individuals. Methods: a cross-sectional, correlational study was conducted. The universe consisted of the population aged 15 to 74 years in Cienfuegos municipality; the sample included 644 people. The variables were: sex, skin color, age, total cholesterol, HDL cholesterol, fasting blood glucose, smoking, baseline systolic blood pressure, cardiovascular reactivity, and risk of cardiovascular morbidity. The risk of cardiovascular morbidity was calculated by applying the Framingham Risk Functions. The Pearson’s Chi-square test and the prevalence ratio were used with a 95 % confidence interval. The direction of the relationship between cardiovascular reactivity, age, and systolic blood pressure was analyzed considering the Eta value. Results: the prevalence of cardiovascular hyperreactivity was higher among people aged 65 to 74 years and males. A higher risk of cardiovascular morbidity was observed in cardiovascular hyperreactive individuals. There is an association between non-optimal systolic blood pressure, increasing age, and high risk of cardiovascular morbidity in cardiovascular hyperreactive people. Conclusions: the risk of cardiovascular morbidity is higher in cardiovascular hyperreactive individuals than in normoreactive people. Age and systolic blood pressure showed greater association with high risk of cardiovascular morbidity.

  3. Nuclear imaging of cardiovascular disease

    International Nuclear Information System (INIS)

    Nuclear imaging methods provide noninvasive indexes of myocardial function, perfusion, and metabolism and are well accepted in clinical cardiology. Advances in prevention and treatment of cardiac disease have resulted in decreasing cardiovascular mortality in industrialized nations. The improvement in therapeutic options has increased the demand for diagnostic tests that might guide clinical decision making. Information beyond the pure anatomic characterization of coronary stenoses is required. Nuclear imaging can be used for early detection and monitoring of the severity and extent of disease. The prognostic potential of such functional testing is being increasingly appreciated and used to guide therapy, thereby resulting in improvement of the quality and cost-effectiveness of the workup of patients with cardiovascular disease. Extensive clinical validation has resulted in growing acceptance of these techniques. Furthermore, ongoing improvement of imaging techniques and development of new radiopharmaceuticals will pave the way for disease-specific, molecular-targeted cardiac imaging in the future. (orig.)

    Full Text Available Midlife cardiovascular risk factors, including diabetes, hypertension, dyslipemia, and an unhealthy lifestyle, have been linked to subsequent incidence, delay of onset, and progression rate of Alzheimer disease and vascular dementia. Conversely, optimal treatment of cardiovascular risk factors prevents and slows down age-related cognitive disorders. The impact of antihypertensive therapy on cognitive outcome in patients with hypertension was assessed in large trials which demonstrated a reduction in progression of MRI white matter hyperintensities, in cognitive decline and in incidence of dementia. Large-scale database correlated statin use and reduction in the incidence of dementia, mainly in patients with documented atherosclerosis, but clinical trials failed to reach similar conclusions. Whether a multitargeted intervention would substantially improve protection, quality of life, and reduce medical cost expenditures in patients with lower risk profile has not been ascertained. This would require appropriately designed trials targeting large populations and focusing on cognitive decline as a primary outcome endpoint.

    Many, but not all people experience diminished health, performance and well-being as a function of exposure to stress. However, the underlying neurophysiological processes which characterize hardy or resilient people are not well understood. This study examines psychological hardiness and several indicators of cardiovascular health, including body mass index (BMI) and blood cholesterol markers in a sample of 338 middle-aged adults enrolled in a national security education program. Hierarchical regression analyses reveal that after controlling for the influence of age and sex, high hardiness is related to higher HDL - high density lipoprotein and less body fat (BMI). Lower hardiness is associated with greater total cholesterol to HDL ratio, a cardiovascular disease risk factor. These results suggest that psychological hardiness confers resilience in part through an influence on cholesterol production and metabolism. PMID:26652199

    The recently devised therapy for psoriasis and related skin diseases, consisting of long-wave ultraviolet light and oral 8-methoxypsoralen (PUVA), was investigated for its cardiovascular effects. In seventeen patients, long-wave ultraviolet light therapy in a treatment enclosure (mean duration, 19.3 minutes) resulted in ambient temperatures of 39.2 degrees C +/- 2.1 degrees C (SD) and skin temperatures of 38.2 degrees C +/- 1.4 degrees C. In upright subjects, heart rate rose 30.8% to 114.4 +/- 25.2 beats per minute (bpm). Intensive room air conditioning, outside of the treatment enclosure, although significantly lowering skin and ambient temperatures, did not affect the heart rates significantly. PUVA therapy is associated with a definite cardiovascular stress when the box type of therapeutic unit is used. Possible modifications are discussed

    For more than 15 years the A-bomb survivor studies have shown increased noncancer mortality due to radiation exposures. The most prominent cause of this increase is circulatory disease mortality. Although the estimated relative risk is less than for solid cancers (1.2 versus 1.6 per Sv), there are measurable increases in cardiovascular disease mortality at doses greater than 0.5 Sv. The evidence for circulatory diseases in mortality studies of occupational cohorts exposed to external radiation is less compelling. It is generally accepted that atherosclerosis is an inflammatory disease of the arteries and a risk factor for myocardial infarction. Immunological markers for inflammatory disease have been shown to be dose related in A-bomb survivors. Evidence from animal studies reveals increased cardiovascular mortality and arterial endothelial damage from both neutron and, to a lesser extent, gamma exposures. PMID:17119211

    The cardiovascular sequelae of radiation exposure are an important cause of morbidity and mortality following radiation therapy for cancer, as well as after exposure to radiation after atomic bombs or nuclear accidents. In the United States, most of the data on radiation-induced heart disease (RIHD) come from patients treated with radiation therapy for Hodgkin disease and breast cancer. Additionally, people exposed to radiation from the atomic bombs in Hiroshima and Nagasaki, Japan, and the Chernobyl, Ukraine, nuclear accident have an increased risk of cardiovascular disease. The total dose of radiation, as well as the fractionation of the dose, plays an important role in the development of RIHD. All parts of the heart are affected, including the pericardium, vasculature, myocardium, valves, and conduction system. The mechanism of injury is complex, but one major mechanism is injury to endothelium in both the microvasculature and coronary arteries. This likely also contributes to damage and fibrosis within the myocardium. Additionally, various inflammatory and profibrotic cytokines contribute to injury. Diagnosis and treatment are not significantly different from those for conventional cardiovascular disease; however, screening for heart disease and lifelong cardiology follow-up is essential in patients with past radiation exposure.

    Robotic technology has been used in cardiovascular medicine since the late 1990s. Interventional cardiology, electrophysiology, endovascular surgery, minimally invasive cardiac surgery, and laparoscopic vascular surgery are all fields of application. Robotic devices enable endoscopic reconstructive surgery in narrow spaces and fast, very precise placement of catheters and devices in catheter-based interventions. In all robotic systems, the operator manipulates the robotic arms from a control station or console. In the field of cardiac surgery, mitral valve repair, CABG surgery, atrial septal defect repair, and myxoma resection can be achieved using robotic technology. Furthermore, vascular surgeons can perform a variety of robotically assisted operations to treat aortic, visceral, and peripheral artery disease. In electrophysiology, ablation procedures for atrial fibrillation can be carried out with robotic support. In the past few years, robotically assisted percutaneous coronary intervention and abdominal aortic endovascular surgery techniques have been developed. The basic feasibility and safety of robotic approaches in cardiovascular medicine has been demonstrated, but learning curves and the high costs associated with this technology have limited its widespread use. Nonetheless, increased procedural speed, accuracy, and reduced exposure to radiation and contrast agent in robotically assisted catheter-based interventions, as well as reduced surgical trauma and shortened patient recovery times after robotic cardiovascular surgery are promising achievements in the field.

Mas temos que morrer por alguma coisa.

    Morrer por causa cardiovascular não é desonroso, nem refere-se à atenção clínica imperfeita. O fato de a primeira causa de morte ser a cardiovascular não tem nenhuma relação com os cuidados clínicos e nem deveria assustar.

No presente artigo é relatado caso de crise porfírica inicialmente diagnosticado como abdômen agudo e tratado com laparotomia exploradora inconclusiva, seguido de revisão de literatura. Durante o pós operatório o quadro evoluiu com sinais neurológicos de tetraparesia, tetraplegia e desconforto respiratório que sugeriam o diagnóstico de síndrome de Guillain-Barré, hipótese afastada após análise do líquor que não mostrou dissociação albumino-citológica. Admitida em unidade de terapia intensiva, dado o quadro neurológico e a necessidade de suporte ventilatório, apresentou colúria e crises convulsivas sendo feita a hipótese de crise porfírica, confirmada com a dosagem de porfirinas na urina de 24 horas. Iniciado o tratamento de suporte, porém, sem o uso de derivados do heme devido a indisponibilidade, a paciente evoluiu com infecção hospitalar, disfunção orgânica e óbito. A porfiria deve ser levada em consideração nos casos agudos de dor abdominal de causa desconhecida, associada a sinais neurológicos como paresias, distúrbios hidroeletrolíticos e psiquiátricos, especialmente em pacientes com presença de fatores precipitantes, história de crises recorrentes e história familiar positiva para porfiria.

    Two concepts, positive health and cardiovascular health, have emerged recently from the respective fields of positive psychology and preventive cardiology. These parallel constructs are converging to foster positive cardiovascular health and a growing collaboration between psychologists and cardiovascular scientists to achieve significant improvements in both individual and population cardiovascular health. We explore these 2 concepts and note close similarities in the measures that define them, the health states that they aim to produce, and their intended long-term clinical and public health outcomes. We especially examine subjective health assets, such as optimism, that are a core focus of positive psychology, but have largely been neglected in preventive cardiology. We identify research to date on positive cardiovascular health, discuss its strengths and limitations thus far, and outline directions for further engagement of cardiovascular scientists with colleagues in positive psychology to advance this new field.

    The cardiovascular deconditioning observed during and after space flight is characterized in a review of human space and simulation studies and animal simulations. The various simulation techniques (horizontal bed rest, head-down tilt, and water immersion in man, and immobilization of animals) are examined, and sample results are presented in graphs. Countermeasures such as exercise regimens, fluid replacement, drugs, venous pooling, G-suits, oscillating beds, electrostimulation of muscles, lower-body negative pressure, body-surface cooling, and hypoxia are reviewed and found to be generally ineffective or unreliable. The need for future space experimentation in both humans and animals is indicated.

    In the past ten years digital image processing has contributed decisively to the advance of cardiovascular radiology. Not only images of better diagnostic value could be produced, but also in many cases the risk for the patient was diminished. In this paper three topics are discussed: One of the principal methods is digital angiography especially with functional imaging. In addition, because of the rapid progress of digital imaging data compression became a major issue. Finally there is a good chance that 3D-processing of MRI data will at least partly replace the present invasive techniques

    A multitude of modifiable risk factors during the median phase of life are often causative for cognitive dysfunction (CD) in old age. High evidence exists for cigarette smoking, diabetes, physical inactivity and sleeping disorders. Single large scale population based studies proof it for hypertension, hypercholesterinemia and depression, conflicting evidence exists for obesity and work stress. Little attention is paid to the close association between cardiovascular disease conditions and CD, particularly for atrial fibrillation, heart failure and for older patients with coronary heart disease. Undetected CD may be responsible for non-adherence and failure of self-care programs in chronic heart patients. PMID:27557067

    The cardiovascular surgery in China has achieved great progress both on scale and technology though development over the past thirty years. However, the technical predominance of cardiovascular surgery in therapies for some diseases has been weakened, along with developments of new drugs and interventional technology. Besides, the change of doctor-patient relationship result from internet medical information service and less attraction of cardiovascular surgery discipline to talents bring certain challenge to the development of cardiovascular surgery. Currently, cardiovascular surgeons should practice the "patient first" principle, carry out individual customized treatment and precision therapy, absorb the advantages of other subjects like intervention and imaging in order to achieve technological breakthroughs, create new treatment technologies and models with smaller trauma and better outcome, establish heart team to provide patient oriented treatment. Besides, cardiovascular surgeons should improve knowledge system by learning related technology and science, become hybrid doctors of research. Cardiovascular surgeons should pay high attention to critical effect of research on the disciplinary development, carry out question and demand oriented clinical studies, change the medical practice by virtue of research achievements, direct the treatment for cardiovascular diseases, and finally provide better health service and rebuild the predominance of cardiovascular surgery.

    Cardiovascular needles are now being manufactured from new stainless steel alloys containing high concentrations of nickel, Surgalloy and Ethalloy. The purpose of this study was to compare the biomechanical performance of a cardiovascular needle made of Surgalloy with a comparably sized needle made of Ethalloy. The parameters of biomechanical performance included sharpness, maintenance of sharpness, resistance to bending, and ductility. Because the biomechanical performance of these needles was remarkably similar, cardiovascular needles made of either the Surgalloy or Ethalloy alloys are recommended for cardiovascular surgery.

  9. Radiation-induced cardiovascular effects

    Science.gov (United States)

    Tapio, Soile

    Recent epidemiological studies indicate that exposure to ionising radiation enhances the risk of cardiovascular mortality and morbidity in a moderate but significant manner. Our goal is to identify molecular mechanisms involved in the pathogenesis of radiation-induced cardiovascular disease using cellular and mouse models. Two radiation targets are studied in detail: the vascular endothelium that plays a pivotal role in the regulation of cardiac function, and the myocardium, in particular damage to the cardiac mitochondria. Ionising radiation causes immediate and persistent alterations in several biological pathways in the endothelium in a dose- and dose-rate dependent manner. High acute and cumulative doses result in rapid, non-transient remodelling of the endothelial cytoskeleton, as well as increased lipid peroxidation and protein oxidation of the heart tissue, independent of whether exposure is local or total body. Proteomic and functional changes are observed in lipid metabolism, glycolysis, mitochondrial function (respiration, ROS production etc.), oxidative stress, cellular adhesion, and cellular structure. The transcriptional regulators Akt and PPAR alpha seem to play a central role in the radiation-response of the endothelium and myocardium, respectively. We have recently started co-operation with GSI in Darmstadt to study the effect of heavy ions on the endothelium. Our research will facilitate the identification of biomarkers associated with adverse cardiac effects of ionising radiation and may lead to the development of countermeasures against radiation-induced cardiac damage.

  10. Marijuana Use and Cardiovascular Disease.

    2016-01-01

    Marijuana is currently the most used illicit substance in the world. With the current trend of decriminalization and legalization of marijuana in the US, physicians in the US will encounter more patients using marijuana recreationally over a diverse range of ages and health states. Therefore, it is relevant to review marijuana's effects on human cardiovascular physiology and disease. Compared with placebo, marijuana cigarettes cause increases in heart rate, supine systolic and diastolic blood pressures, and forearm blood flow via increased sympathetic nervous system activity. These actions increase myocardial oxygen demand to a degree that they can decrease the time to exercise-induced angina in patients with a history of stable angina. In addition, marijuana has been associated with triggering myocardial infarctions (MIs) in young male patients. Smoking marijuana has been shown to increase the risk of MI onset by a factor of 4.8 for the 60 minutes after marijuana consumption, and to increase the annual risk of MI in the daily cannabis user from 1.5% to 3% per year. Human and animal models suggest that this effect may be due to coronary arterial vasospasm. However, longitudinal studies have indicated that marijuana use may not have a significant effect on long-term mortality. While further research is required to definitively determine the impact of marijuana on cardiovascular disease, it is reasonable to recommend against recreational marijuana use, especially in individuals with a history of coronary artery disorders.

  16. Cardiovascular Reactivity, Stress, and Physical Activity

    Chun-Jung eHuang

    2013-11-01

    Full Text Available Psychological stress has been proposed as a major contributor to the progression of cardiovascular disease (CVD. Acute mental stress can activate the sympathetic-adrenal-medullary (SAM axis, eliciting the release of catecholamines (NE and EPI resulting in the elevation of heart rate (HR and blood pressure (BP. Combined stress (psychological and physical can exacerbate these cardiovascular responses, which may partially contribute to the elevated risk of CVD and increased proportionate mortality risks experienced by some occupations (e.g., firefighting and law enforcement. Studies have supported the benefits of physical activity on physiological and psychological health, including the cardiovascular response to acute stress. Aerobically trained individuals exhibit lower sympathetic nervous system (e.g., HR reactivity and enhanced cardiovascular efficiency (e.g., lower vascular reactivity and decreased recovery time in response to physical and/or psychological stress. In addition, resistance training has been demonstrated to attenuate cardiovascular responses and improve mental health. This review will examine stress-induced cardiovascular reactivity and plausible explanations for how exercise training and physical fitness (aerobic and resistance exercise can attenuate cardiovascular responses to stress. This enhanced functionality may facilitate a reduction in the incidence of stroke and myocardial infarction. Finally, this review will also address the interaction of obesity and physical activity on cardiovascular reactivity and CVD.

    Cardiovascular disease is the leading cause of morbidity and mortality in postmenopausal women. Although it is a disease of aging, vascular disease initiates much earlier in life. Thus, there is a need to be aware of the potential to prevent the development of the disease from an early age and continue this surveillance throughout life. The menopausal period and early menopause present an ideal opportunity to assess cardiovascular risk and plan accordingly. Generally in this period, women will be seen by primary health-care professionals and non-cardiovascular specialists. This review addresses female-specific risk factors that may contribute to the potential development of cardiovascular disease. It is important for all health-care professionals dealing with women in midlife and beyond to be cognisant of these risk factors and to initiate female-specific preventative measures or to refer to a cardiovascular specialist.

    Full Text Available Recent studies demonstrated that mitochondria play an important role in the cardiovascular system and mutations of mitochondrial DNA affect coronary artery disease, resulting in hypertension, atherosclerosis, and cardiomyopathy. Traditional Chinese medicine (TCM has been used for thousands of years to treat cardiovascular disease, but it is not yet clear how TCM affects mitochondrial function. By reviewing the interactions between the cardiovascular system, mitochondrial DNA, and TCM, we show that cardiovascular disease is negatively affected by mutations in mitochondrial DNA and that TCM can be used to treat cardiovascular disease by regulating the structure and function of mitochondria via increases in mitochondrial electron transport and oxidative phosphorylation, modulation of mitochondrial-mediated apoptosis, and decreases in mitochondrial ROS. However further research is still required to identify the mechanism by which TCM affects CVD and modifies mitochondrial DNA.

    It is well known that regular moderate physical activity, in the context of a healthy lifestyle, significantly reduces the likelihood of cardiovascular events, both in primary and secondary prevention. In addition, it is scientifically proven that exercise can reduce the incidence of diabetes, osteoporosis, depression, breast cancer and colon cancer. Despite this strong evidence, sedentary lifestyle remains a widespread habit in the western world. Even in Italy the adult population has a poor attitude to regular physical activity. It is therefore necessary, as continuously recommended by the World Health Organization, to motivate people to "move" since the transition from inactivity to regular light to moderate physical activity has a huge impact on health, resulting in significant savings of resources. We do not need to be athletes to exercise - it should be part of all our daily routines. PMID:27029874

    Full Text Available Eggs are a major source of phospholipids (PL in the Western diet. Dietary PL have emerged as a potential source of bioactive lipids that may have widespread effects on pathways related to inflammation, cholesterol metabolism, and high-density lipoprotein (HDL function. Based on pre-clinical studies, egg phosphatidylcholine (PC and sphingomyelin appear to regulate cholesterol absorption and inflammation. In clinical studies, egg PL intake is associated with beneficial changes in biomarkers related to HDL reverse cholesterol transport. Recently, egg PC was shown to be a substrate for the generation of trimethylamine N-oxide (TMAO, a gut microbe-dependent metabolite associated with increased cardiovascular disease (CVD risk. More research is warranted to examine potential serum TMAO responses with chronic egg ingestion and in different populations, such as diabetics. In this review, the recent basic science, clinical, and epidemiological findings examining egg PL intake and risk of CVD are summarized.

    Aerobic exercise training leads to cardiovascular changes that markedly increase aerobic power and lead to improved endurance performance. The functionally most important adaptation is the improvement in maximal cardiac output which is the result of an enlargement in cardiac dimension, improved...... arteries is reduced, a factor contributing to increased arterial compliance. Endurance training may also induce alterations in the vasodilator capacity, although such adaptations are more pronounced in individuals with reduced vascular function. The microvascular net increases in size within the muscle...... allowing for an improved capacity for oxygen extraction by the muscle through a greater area for diffusion, a shorter diffusion distance, and a longer mean transit time for the erythrocyte to pass through the smallest blood vessels.

    2015-01-01

    Full Text Available Polymers have found widespread applications in cardiology, in particular in coronary vascular intervention as stent platforms (scaffolds and coating matrices for drug-eluting stents. Apart from permanent polymers, current research is focussing on biodegradable polymers. Since they degrade once their function is fulfilled, their use might contribute to the reduction of adverse events like in-stent restenosis, late stent-thrombosis, and hypersensitivity reactions. After reviewing current literature concerning polymers used for cardiovascular applications, this review deals with parameters of tissue and blood cell functions which should be considered to evaluate biocompatibility of stent polymers in order to enhance physiological appropriate properties. The properties of the substrate on which vascular cells are placed can have a large impact on cell morphology, differentiation, motility, and fate. Finally, methods to assess these parameters under physiological conditions will be summarized.

    2008-01-01

    Full Text Available Cyclooxygenase (COX, also known as prostaglandin endoperoxide synthase, is the key enzyme required for the conversion of arachidonic acid to prostaglandins. Two COX isoforms have been identified, COX-1 and COX-2. Generally, the COX-1 enzyme is produced constitutively (e.g. in gastric mucosa, whereas COX-2 is highly inducible (e.g. at sites of inflammation and cancer. Traditional non-steroidal anti-inflammatory drugs (NSAIDs inhibit both enzymes, and a new class of COX-2 selective inhibitors (COXIBs preferentially inhibit the COX-2 enzyme. This review summarizes our current understanding of the role of COX-1 and COX-2, with emphasis on their role on cardiovascular biology.

    Doping -the abuse of anabolic-androgenic steroids in particular- is widespread in amateur and recreational sports and does not solely represent a problem of professional sports. Excessive overdose of anabolic steroids is well documented in bodybuilding or powerlifting leading to significant side effects. Cardiovascular damages are most relevant next to adverse endocrine effects.Clinical cases as well as forensic investigations of fatalities or steroid consumption in connection with trafficking of doping agents provide only anecdotal evidence of correlations between side effects and substance abuse. Analytical verification and self-declarations of steroid users have repeatedly confirmed the presumption of weekly dosages between 300 and 2000 mg, extra to the fact that co-administration of therapeutics to treat side-effects represent a routine procedure. Beside the most frequent use of medications used to treat erectile dysfunction or estrogenic side-effects, a substantial number of antihypertensive drugs of various classes, i.e. beta-blockers, diuretics, angiotensin II receptor antagonists, calcium channel blockers, as well as ACE inhibitors were recently confiscated in relevant doping cases. The presumptive correlation between misuse of anabolic steroids and self-treatment of cardiovascular side effects was explicitly confirmed by detailed user statements.Two representative fatalities of bodybuilders were introduced to outline characteristic, often lethal side effects of excessive steroid abuse. Moreover, illustrative autopsy findings of steroid acne, thrombotic occlusion of Ramus interventricularis anterior and signs of cardiac infarctions are presented.A potential steroid abuse should be carefully considered in cases of medical consultations of patients exhibiting apparent constitutional modifications and corresponding adverse effects. Moreover, common self-medications -as frequently applied by steroid consumers- should be taken into therapeutic considerations

    With increasing use of pediatric cardiovascular MRI, it is important for all imagers to become familiar with the spectrum of non-cardiovascular imaging findings that can be encountered. This study aims to ascertain the prevalence and nature of these findings in pediatric cardiovascular MRIs performed at our institution. We retrospectively evaluated reports of all cardiovascular MRI studies performed at our institute from January 2008 to October 2012 in patients younger than18 years. Most studies (98%) were jointly interpreted by a pediatric cardiologist and a radiologist. We reviewed the electronic medical records of all cases with non-cardiovascular findings, defined as any imaging finding outside the cardiovascular system. Non-cardiovascular findings were classified into significant and non-significant, based on whether they were known at the time of imaging or they required additional workup or a change in management. In 849 consecutive studies (mean age 9.7 ± 6.3 years), 145 non-cardiovascular findings were found in 140 studies (16.5% of total studies). Overall, 51.0% (74/145) of non-cardiovascular findings were in the abdomen, 30.3% (44/145) were in the chest, and 18.6% (27/145) were in the spine. A total of 19 significant non-cardiovascular findings were observed in 19 studies in individual patients (2.2% of total studies, 47% male, mean age 5.9 ± 6.7 years). Significant non-cardiovascular findings included hepatic adenoma, arterially enhancing focal liver lesions, asplenia, solitary kidney, pelvicaliectasis, renal cystic diseases, gastric distention, adrenal hemorrhage, lung hypoplasia, air space disease, bronchial narrowing, pneumomediastinum and retained surgical sponge. Non-cardiovascular findings were seen in 16.5% of cardiovascular MRI studies in children, of which 2.2% were clinically significant findings. Prevalence and nature of these non-cardiovascular findings are different from those reported in adults. Attention to these findings is important

    Full Text Available En Argentina, el síndrome de distrés respiratorio agudo (SDRA representa el 7.7% de las admisiones en terapia intensiva y está asociado con una alta morbilidad y mortalidad (58%. Con frecuencia la muerte puede ser atribuida a más de una causa. La hipoxemia refractaria es una causa de muerte poco frecuente (15% y en muchos casos puede coexistir con disfunción multiorgánica, sepsis o shock séptico. La utilidad de los esteroides como parte del tratamiento es aún motivo de debate a pesar de las múltiples series de casos y estudios clínicos publicados. En el artículo se evalúa la utilidad de los esteroides en el SDRA a través de la revisión de la bibliografía disponible. Se concluye que los esteroides estarían indicados en un pequeño subgrupo de pacientes con SDRA no resuelto o tardío, después de descartar o controlar una infección activa.The acute respiratory distress syndrome (ARDS represents 7.7% of the intensive care population, and is associated with great morbidity and mortality (58%. Frequently, the mortality can be attributed to more than one cause. Refractory hypoxemia is uncommon (15% and most of the patients also have multiple organic dysfunction, sepsis or septic shock. Although there are many publications concerning series of cases and clinical trials using steroids as a part of the treatment of ARDS, this issue remains controversial. In this article the role of steroids in the ARDS is evaluated by analysis of the available literature. We conclude that steroids are useful in a subgroup of patients with unresolving ARDS, after ruling out an active infection or after treatment with antibiotics.

  16. Residual generator for cardiovascular anomalies detection

    2014-06-01

    This paper discusses the possibility of using observer-based approaches for cardiovascular anomalies detection and isolation. We consider a lumped parameter model of the cardiovascular system that can be written in a form of nonlinear state-space representation. We show that residuals that are sensitive to variations in some cardiovascular parameters and to abnormal opening and closure of the valves, can be generated. Since the whole state is not easily available for measurement, we propose to associate the residual generator to a robust extended kalman filter. Numerical results performed on synthetic data are provided.

  17. Progestins and cardiovascular risk markers.

    Science.gov (United States)

    Sitruk-Ware, R

    2000-01-01

    Several risks are attributed to progestins as a class-effect; however, the progestins used in hormone replacement therapy (HRT) have varying pharmacologic properties and do not induce the same side effects. Natural progesterone (P) and some of its derivatives, such as the 19-norprogesterones, do not exert any androgenic effect and, hence, have no negative effect on the lipids. On the other hand, the 19-nortestosterone derivatives and even some 17-hydroxyprogesterones have a partial androgenic effect, which may explain some of the negative effects observed on surrogate markers of cardiovascular risk. The relevance of the lipid changes induced by sex steroids has been questioned, and studies in the female cynomolgous monkey have not shown a direct relationship to atherosclerosis. Results suggest that estrogens (E) have antiatherogenic effects and that P does not reverse the beneficial effect of estradiol. Also, sex hormones modulate the vasomotor response of the main arteries. E preserves the normal endothelium-mediated dilation of coronary arteries, and P does not reverse this potential cardioprotective mechanism. In the same animal model, the addition of cyclic or continuous medroxyprogesterone acetate (MPA) to E inhibited vasodilatation by 50%, while nomegestrol acetate did not diminish the E-induced vasodilatation. Not all progestins act similarly on vasomotion or affect cardiovascular risk factors in the same way. Progestins, such as MPA or norethisterone acetate (NETA), exert a partial detrimental effect on the beneficial actions of estrogens with regard to lipid changes, atheroma development, or vasomotion. In contrast, progesterone itself does not have this inhibitory effect on lipid changes and vascular reactivity in animal models or on exercise-induced myocardial ischemia in humans. Nonandrogenic molecules of P itself and of derivatives, such as 19-norprogesterones, would appear neutral on the vessels. Several ongoing randomized controlled trials of HRT are

    Cardiovascular disease (CVD) is the leading cause of death and hospitalization in both men and women in nearly all countries of Europe. The most frequent forms of CVD are those of an atherosclerotic origin, mainly ischaemic heart disease, stroke and heart failure. The magnitude of the problem contrasts with the usual paucity and poor quality of data available on incidence and prevalence of CVD, except for few rigorous but limited studies. The objectives of the health interview and health examination surveys (HIS/HES) are to evaluate the frequency and the distribution of the disease, to evaluate trends and treatment effectiveness, to estimate risk factors distribution and prevalence of high risk conditions and to monitor prevention programmes. According to the EUROCISS project (EUROpean Cardiovascular Surveillance Set) recommendations, surveys are aimed at describing the prevalence of the following CVD conditions: myocardial infarction, heart failure, angina pectoris, peripheral arterial disease, stroke, and ischaemic heart disease.HIS and HES were developed to supplement information collected from routine databases and population-based registers to implement consistent public health policies. HIS can be repeated periodically in a new sample of the population, or can follow up over time the population recruited at baseline. Procedures and methods to collect information from participants include self-administered questionnaires, direct interviewer-administered questions and telephone interviews. A minimum set of questions to be administered every year, along with a longer, more detailed module to be administered periodically are recommended to evaluate CVD prevalence. The addition of HES provides more detailed and objective information that can be used to improve estimates regarding prevalence of both risk factors and disease status. The selection of more specialized CVD-specific tests will depend on the objective the survey is designed to achieve, the assumed

  19. Molecular imaging in cardiovascular diseases

    International Nuclear Information System (INIS)

    Cardiovascular diseases remain the leading cause of morbidity and mortality in industrialized and developing countries. In clinical practice, the in-vivo identification of atherosclerotic lesions, which can lead to complications such as heart attack or stroke, remains difficult. Imaging techniques provide the reference standard for the detection of clinically significant atherosclerotic changes in the coronary and carotid arteries. The assessment of the luminal narrowing is feasible, while the differentiation of stable and potentially unstable or vulnerable atherosclerotic plaques is currently not possible using non-invasive imaging. With high spatial resolution and high soft tissue contrast, magnetic resonance imaging (MRI) is a suitable method for the evaluation of the thin arterial wall. In clinical practice, native MRI of the vessel wall already allows the differentiation and characterization of components of atherosclerotic plaques in the carotid arteries and the aorta. Additional diagnostic information can be gained by the use of non-specific MRI contrast agents. With the development of targeted molecular probes, that highlight specific molecules or cells, pathological processes can be visualized at a molecular level with high spatial resolution. In this review article, the development of pathophysiological changes leading to the development of the arterial wall are introduced and discussed. Additionally, principles of contrast enhanced imaging with non-specific contrast agents and molecular probes will be discussed and latest developments in the field of molecular imaging of the vascular wall will be introduced.

    Molecular imaging strives to visualise processes at the molecular and cellular level in vivo. Understanding these processes supports diagnosis and evaluation of therapeutic efficacy on an individual basis and thereby makes personalised medicine possible. Apoptosis is a well-organised mode of cell suicide that plays a role in cardiovascular diseases (CVD). Apoptosis is associated with loss of cardiomyocytes following myocardial infarction, atherosclerotic plaque instability, congestive heart failure and allograft rejection of the transplanted heart. Thus, apoptosis constitutes an attractive target for molecular imaging of CVD. Our current knowledge about the molecular players and mechanisms underlying apoptosis offers a rich palette of potential molecular targets for molecular imaging. However, only a few have been successfully developed so far. This review highlights aspects of the molecular machinery and biochemistry of apoptosis relevant to the development of molecular imaging probes. It surveys the role of apoptosis in four major areas of CVD and portrays the importance and future perspectives of apoptosis imaging. The annexin A5 imaging protocol is emphasised since it is the most advanced protocol to measure apoptosis in both preclinical and clinical studies. (orig.)

  1. Metabolic syndrome and cardiovascular risk

    Full Text Available The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol, elevated blood pressure, impaired glucose tolerance, and central obesity is now classified as metabolic syndrome, also called syndrome X. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria for use in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general, they include a combination of multiple and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics, commonly manifest a prothrombotic state as well as and a proinflammatory state. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB, increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C. The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of atherosclerotic cardiovascular disease (ASCVD risk factors, that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to the components of the syndrome present as well as the other, non-metabolic syndrome risk factors in a particular person.

  2. Platelet proteomics in cardiovascular diseases

    2015-06-01

    Full Text Available In recent years, platelet proteomics has been applied successfully to the study of cardiovascular diseases (CVDs. It is very well known that platelets play a pivotal role in the pathophysiological mechanisms underlying many CVDs, especially acute coronary syndromes (ACSs, since they are implied in thrombus formation after atheroma plaque rupture. This is the reason why molecules involved in platelet activation and aggregation are primary targets for treatment of ACSs. Many efforts are aimed at finding drugs that inhibit platelet activation; however it is difficult to separate the therapeutic benefits from harmful effects because pathological and physiological functions of platelets are due to the same mechanisms. Given that platelets lack a nucleus, proteomics is regarded as an ideal method to approach their biochemistry. Current platelet proteomic studies are focusing on the identification of platelet molecular and functional changes in normal and pathological states, enriching the comprehension of platelet biological function, and screening for new biomarkers and antiplatelet agents. In the present article, we introduce the reader to platelet biology and function, and revise recent advances in platelet proteomics applied to the study of CVDs, including a special emphasis on sample preparation requirements for proteome analysis of platelet clinical samples.

  3. Cardiovascular Involvement in Autoimmune Diseases

    2014-01-01

    Full Text Available Autoimmune diseases (AD represent a broad spectrum of chronic conditions that may afflict specific target organs or multiple systems with a significant burden on quality of life. These conditions have common mechanisms including genetic and epigenetics factors, gender disparity, environmental triggers, pathophysiological abnormalities, and certain subphenotypes. Atherosclerosis (AT was once considered to be a degenerative disease that was an inevitable consequence of aging. However, research in the last three decades has shown that AT is not degenerative or inevitable. It is an autoimmune-inflammatory disease associated with infectious and inflammatory factors characterized by lipoprotein metabolism alteration that leads to immune system activation with the consequent proliferation of smooth muscle cells, narrowing arteries, and atheroma formation. Both humoral and cellular immune mechanisms have been proposed to participate in the onset and progression of AT. Several risk factors, known as classic risk factors, have been described. Interestingly, the excessive cardiovascular events observed in patients with ADs are not fully explained by these factors. Several novel risk factors contribute to the development of premature vascular damage. In this review, we discuss our current understanding of how traditional and nontraditional risk factors contribute to pathogenesis of CVD in AD.

    Full Text Available Abstract Background Little is known regarding the cardiovascular disease risk factors among Chamorros residing in the United States. Methods The Chamorro Directory International and the CDC's Behavioral Risk Factor Surveillance System Questionnaire (BRFSS were used to assess the health related practices and needs of a random sample of 228 Chamorros. Results Inactivity, hypertension, elevated cholesterol and diabetes mellitus were more prevalent in this Chamorro sample compared to the US average. Participants who were 50-and-older or unemployed were more likely to report hypertension, diabetes and inactivity, but they were also more likely to consume more fruits and vegetables than their younger and employed counterparts. Women were more likely to report hypertension and diabetes, whereas men were more likely to have elevated BMI and to have never had their blood cholesterol checked. Conclusion The study provides data that will help healthcare providers, public health workers and community leaders identify where to focus their health improvement efforts for Chamorros and create culturally competent programs to promote health in this community.

  5. Matriarchal model for cardiovascular prevention.

    1994-02-01

    Family patterns of cardiovascular risk behavior are well documented. Significant correlation exists between spouse-spouse, parent-child, and sibling-sibling for cholesterol, high- and low-density lipoprotein, diet, physical activity, and smoking. Family/environmental influences are important in how/if risk and/or preventive behavior is learned. The family matriarch commonly functions as gatekeeper, controlling eating behavior, access to health care, and other patterns. She often acts as menu planner, shopper, and preparer of meals for all family members. She provides information and verbal reinforcement about food and is a powerful model concerning dietary practices. In fact, the mother, as head of household in most single-parent families, may be the only adult model for many children. Because relevance and credibility are the most important characteristics of a behavioral model, parents (especially mothers) are strong models for observational learning by children. Risk factor information and risk reduction activities adopted by the matriarch can be generalized to the entire family if she learns the skills to act as a change agent. Initiation of this process of education and training the matriarch lies with primary care providers for women (Ob-Gyns see most women). By teaching risk reduction to the matriarch as a component of primary care, physician interaction can have a rippling effect. PMID:8164913

  6. Pomegranate for Your Cardiovascular Health

    Full Text Available Pomegranate is a source of some very potent antioxidants (tannins, anthocyanins which are considered to be also potent anti-atherogenic agents. The combination of the above unique various types of pomegranate polyphenols provides a much wider spectrum of action against several types of free radicals. Indeed, pomegranate is superior in comparison to other antioxidants in protecting low-density lipoprotein (LDL, “the bad cholesterol” and high-density lipoprotein (HDL, “the good cholesterol” from oxidation, and as a result it attenuates atherosclerosis development and its consequent cardiovascular events. Pomegranate antioxidants are not free, but are attached to the pomegranate sugars, and hence were shown to be beneficial even in diabetic patients. Furthermore, pomegranate antioxidants are unique in their ability to increase the activity of the HDL-associated paraoxonase 1 (PON1, which breaks down harmful oxidized lipids in lipoproteins, in macrophages, and in atherosclerotic plaques. Finally, unique pomegranate antioxidants beneficially decrease blood pressure. All the above beneficial characteristics make the pomegranate a uniquely healthy fruit.

    2016-02-01

    Can we estimate the consequences of world military expenditures for the physical and mental health of nations that produce and purchase armaments? If anxiety and fear are promoting military expenditures, then those sentiments may well reflect poorer mental health and war-related stress as it influences cardiovascular illness rates. Further, extensive military expenditure by a society implies that other societal needs are allocated fewer resources, including nutrition, water and sanitation, health care, and economic development. We use a model focused on military expenditures to predict cardiovascular mortality in world samples of industrialized and developing countries over 2000-2011. The cardiovascular mortality model controls for economic development, smoking, body mass index, systolic blood pressure, and carbon dioxide emissions. Military expenditures as proportion of gross domestic product show significant positive relations to cardiovascular disease mortality in linear multiple regression analyses, using both cross-sectional and pooled cross-sectional time-series approaches.

    Full Text Available Considering the high mortality and morbidity rate associated with cardiovascular diseases, Cardiacrehabilitation (CR is regarded for prevention and management of cardiovascular diseases. CR servicesare generally provided in an outpatient as comprehensive, long-term programs involving medicalevaluation, prescribed exercise, cardiac risk factor modification, education and counseling. This includesnutritional therapies, weight loss program management of lipid abnormalities with diet and medication,blood pressure control, diabetes management and stress management. The exercise component of a totalapproach to rehabilitation helps to overcome the fears and anxieties that so many people experience aftera heart attack. Aerobic exercise training program improves cardiovascular fitness in both healthyindividual and cardiac patients. Cardiac rehabilitation prevents and treat cardiovascular disease, reducescardiac risk factors, improving patient’s exercise capacity and enhancing quality of life. Aerobicexercise with intensity of approximately 60 to 70% of the maximal heart rate for 30 to 60 minutes, 3 to 4times a week, for 4 to 6 weeks enhances exercise capacity.

    Full Text Available Psoriatic arthritis (PsA is an inflammatory arthritis associated with psoriasis. In addition to skin and joint involvement, there is increasing evidence suggesting that patients with PsA also have an increase in risk of clinical and subclinical cardiovascular diseases, mostly due to accelerating atherosclerosis. Both conventional and nonconventional cardiovascular risk factors contribute to the increased cardiovascular risk in PsA. Chronic inflammation plays a pivotal role in the pathogenesis of atherosclerosis in PsA, acting independently and/or synergistically with the conventional risk factors. In this paper, we discuss the current literature indicating that patients with PsA are at risk of cardiovascular diseases.

    Psychological stress has been proposed as a major contributor to the progression of cardiovascular disease (CVD). Acute mental stress can activate the sympathetic-adrenal-medullary (SAM) axis, eliciting the release of catecholamines (NE and EPI) resulting in the elevation of heart rate (HR) and blood pressure (BP). Combined stress (psychological and physical) can exacerbate these cardiovascular responses, which may partially contribute to the elevated risk of CVD and increased proportionate...

    Future long-distance space missions will be associated with significant exposures to ionizing radiation, and the health risks of these radiation exposures during manned missions need to be assessed. Recent Earth-based epidemiological studies in survivors of atomic bombs and after occupational and medical low dose radiation exposures have indicated that the cardiovascular system may be more sensitive to ionizing radiation than was previously thought. This has raised the concern of a cardiovascular disease risk from exposure to space radiation during long-distance space travel. Ground-based studies with animal and cell culture models play an important role in estimating health risks from space radiation exposure. Charged particle space radiation has dense ionization characteristics and may induce unique biological responses, appropriate simulation of the space radiation environment and careful consideration of the choice of the experimental model are critical. Recent studies have addressed cardiovascular effects of space radiation using such models and provided first results that aid in estimating cardiovascular disease risk, and several other studies are ongoing. Moreover, astronauts could potentially be administered pharmacological countermeasures against adverse effects of space radiation, and research is focused on the development of such compounds. Because the cardiovascular response to space radiation has not yet been clearly defined, the identification of potential pharmacological countermeasures against cardiovascular effects is still in its infancy.

  8. Dietary fibre and cardiovascular health.

    Cardiovascular disease (CVD) is the leading cause of mortality and morbidity in developed countries. CVD is an inflammatory disease associated with risk factors that include hypercholesterolemia and hypertension. Furthermore, the evolution of this disease depends on the amount of modified lipoproteins (e.g. oxidized) present in the arterial subendothelium. Diet is considered the cornerstone for CVD treatment, as it can lower not only atherogenic lipoprotein levels and degree of oxidation, but also blood pressure, thrombogenesis and concentrations of some relevant factors (e.g. homocystein).Among different diets, the Mediterranean diet stands out due to their benefits on several health benefits, in particular with regard to CVD. Rich in vegetable foods, this diet contributes both quantitatively and qualitatively to essential fibre compounds (cellulose, hemicellulose, gums, mucilages, pectins, oligosaccharides, lignins, etc.). The present paper analyzes the effects of fibre consumption on a) cholesterol and lipoprotein levels; b) systolic and diastolic blood pressures; and c) antioxidant availability and profile. Some studies and meta-analysis are revised, as the possible mechanisms by which fibre may decrease plasma total cholesterol and LDL-cholesterol and blood pressure and to act as antioxidant, as well. In addition, author's own publications regarding the effect of fibre matrix (e.g. seaweeds) on arylesterase and the gene expression of some key antioxidant enzymes are reviewed. The paper also includes data concerning the possible interaction between fibre and some hypolipemic drugs, which may make it possible to attain similar hypolipemic effects with lower dosages, with the consequent decrease in possible side effects. The review concludes with a summary of nutritional objectives related to the consumption of carbohydrates and fibre supplements. PMID:22566302

El costo se evaluó con la metodología del ABC. RESULTADOS: El mejoramiento de las actividades de atención en el servicio de Clínica Médica conllevaría un ahorro sustancial en los costos indirectos, equivalente a un porcentaje promedio de 7.11 sobre los productos definidos como consultas por hipertensión arterial (HTA, dislipidemia y diabetes. El ahorro total en el costo unitario por producto que se produciría si se eliminaran las actividades mencionadas, estaría en el orden de 11.78% para el producto HTA, de 13.96% para dislipidemia, de 19.05% para diabetes y de 11.45% para las enfermedades no trazadores. Se asignó o se gastó ineficientemente 66.26% de los costos totales indirectos correspondientes al producto dislipidemia y 61.80% de los correspondientes a diabetes. El costo unitario total de las consultas en el servicio de Clínica Médica, según el método tradicional, es de $22.98, valor que en algunos casos está muy por debajo del costo obtenido a partir del método ABC aplicado en este estudio. CONCLUSIONES: Es necesario trabajar en el rediseño del proceso de atención para evaluar las actividades que no agreguen valor al mismo; éstas únicamente generan molestias y demoras al paciente y provocan ineficiencias en el sistema, dado que se asignan recursos a actividades que no optimizan la gestión y, como

A doença espontânea ocorreu após transferência de bovinos de pastagem madura e seca para outra jovem e viçosa. Todos os bovinos afetados eram vacas das raças holandês e pardo suíço. Os principais sinais clínicos foram dispneia e respiração abdominal dificultosa com o pescoço estendido e a boca aberta. Apresentaram, também, enfisema subcutâneo, queda na produção de leite e recuperação lenta ou morte. Os achados de necropsia foram restritos ao pulmão o qual tinha coloração vermelho escuro, não colabado, de aspecto brilhante e hipercriptante com enfisema interlobular acentuado. As lesões histológicas no pulmão consistiam principalmente de enfisema alveolar e interlobular intercalado por áreas de congestão e edema, degeneração hialina da parede dos alvéolos e infiltrado de macrófagos e eosinófilos, moderado, difuso. A reprodução experimental da doença foi realizada em um bovino, com administração de 0,7mg/kg de peso corporal de L-triptofano por via oral em dose única. O animal morreu no sétimo dia de experimento. Os sinais clínicos e lesões foram idênticos aos observados na doença espontânea.

    Full Text Available INTRODUÇÃO: O alongamento é uma técnica terapêutica e pode ser utilizada como forma de aquecimento para aumentar a flexibilidade ou diminuir a dor ao longo do movimento, com objetivos na melhora da performance e redução do risco de lesões. OBJETIVO: Verificar os efeitos agudos e crônicos de um programa de alongamento estático em relação ao dinâmico na performance em jovens atletas do futebol. MÉTODOS: Estudo clínico randomizado de equivalência realizado entre agosto e novembro de 2010 junto à categoria sub-17 do Grêmio Torrense. Após preencherem os critérios de inclusão, atletas foram aleatoriamente alocados em dois grupos: alongamento estático ou alongamento dinâmico. Todos realizaram uma avaliação inicial e foram submetidos à primeira intervenção. Após, foram novamente avaliados e ao término de 12 sessões de treinamento. Foram avaliadas as valências flexibilidade, impulsão, velocidade, força e recrutamento muscular. RESULTADOS: A impulsão horizontal melhorou significativamente nos dois grupos do estudo, porém esta melhora persistiu na fase crônica apenas no grupo alongamento estático (p = 0,02. A flexibilidade aumentou significativamente em ambos os grupos na fase aguda, porém só no grupo estático se verificou o seguimento desta melhora na fase crônica (p = 0,03. As duas formas de alongamento levaram a perda de rendimento no teste de velocidade. Não se observou melhora da força muscular de isquiotibiais ao longo do período do estudo em ambos os grupos. A atividade elétrica dos isquiotibiais diminuiu significativamente na fase aguda para o grupo alongamento estático (p = 0,035 e aumentou significativamente na fase crônica no grupo alongamento dinâmico (p = 0,038. CONCLUSÃO: Neste estudo conclui-se que alongamentos de forma estática melhoram a flexibilidade e impulsão horizontal, enquanto que alongamentos dinâmicos melhoram a ativação muscular.

  2. Ethical considerations in cardiovascular prevention.

    The fundamental values in medical ethics include the following aspects of professional conduct: (i) actions in the best interest of patients; (ii) first, do no harm; (iii) patients' right to refuse or choose treatments; (iv) fairness and equality in the distribution of healthcare resources; and (v) truthfulness and honesty (informed consent). These values have to be considered in all diagnostic steps and therapeutic decisions. They should also form the basis for discussions of potential conflicts of interest among patients, doctors, healthcare financers and politicians. Cardiovascular (CV) diseases represent the most frequent cause of death and a major healthcare problem in most regions of the world. CV prevention is therefore an important task both in individual subjects and as a means to improve health in the general population. While the merits of treatment in patients with established CV diseases, i.e. secondary prevention, are widely accepted and regarded as necessary, primary prevention with drugs in apparently healthy individuals at an increased risk of future CV events is not free of controversies. The different types of prevention envisaged also give rise to ethical questions: Should all the growing number of classical and newly recognised CV risk markers be a reason for intervention or should they be preferably used for calculating a total risk score? What are the compelling or only relative indications for anti-hypertensive, cholesterol-lowering, anti-diabetic or platelet-inhibiting drugs? Are pre-hypertension, pre-diabetes and marginally elevated cholesterol levels early diseases justifying drug treatment, regardless of the possibility that some prophylactic interventions may be associated with adverse events? Discussions also often arise concerning the role of age, gender and of non-CV co-morbidities for decisions about long-term prevention with drugs. How reliable and applicable are 'evidence-based' guidelines derived from trials in highly selected

    Full Text Available Oxytocin (OT, a nonapeptide, was the first hormone to have its biological activities established and chemical structure determined. It was believed that OT is released from hypothalamic nerve terminals of the posterior hypophysis into the circulation where it stimulates uterine contractions during parturition, and milk ejection during lactation. However, equivalent concentrations of OT were found in the male hypophysis, and similar stimuli of OT release were determined for both sexes, suggesting other physiological functions. Indeed, recent studies indicate that OT is involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of cardiovascular functions. It has long been known that OT induces natriuresis and causes a fall in mean arterial pressure, both after acute and chronic treatment, but the mechanism was not clear. The discovery of the natriuretic family shed new light on this matter. Atrial natriuretic peptide (ANP, a potent natriuretic and vasorelaxant hormone, originally isolated from rat atria, has been found at other sites, including the brain. Blood volume expansion causes ANP release that is believed to be important in the induction of natriuresis and diuresis, which in turn act to reduce the increase in blood volume. Neurohypophysectomy totally abolishes the ANP response to volume expansion. This indicates that one of the major hypophyseal peptides is responsible for ANP release. The role of ANP in OT-induced natriuresis was evaluated, and we hypothesized that the cardio-renal effects of OT are mediated by the release of ANP from the heart. To support this hypothesis, we have demonstrated the presence and synthesis of OT receptors in all heart compartments and the vasculature. The functionality of these receptors has been established by the ability of OT to induce ANP release from perfused heart or atrial slices. Furthermore, we have shown that the heart and large vessels

    Full Text Available Peroxisome proliferators activated receptors (PPARs are ligand-activated nuclear transcription factors that play important roles in lipid and glucose homeostasis. To the extent that PPAR agonists improve diabetic dyslipidaemia and insulin resistance, these agents have been considered to reduce cardiovascular risk. However, data from murine models suggests that PPAR agonists also have independent anti-atherosclerotic actions, including the suppression of vascular inflammation, oxidative stress, and activation of the renin angiotensin system. Many of these potentially anti-atherosclerotic effects are thought to be mediated by transrepression of nuclear factor-kB, STAT, and activator protein-1 dependent pathways. In recent clinical trials, PPARα agonists have been shown to be effective in the primary prevention of cardiovascular events, while their cardiovascular benefit in patients with established cardiovascular disease remains equivocal. However, the use of PPARγ agonists, and more recently dual PPARα/γ coagonists, has been associated with an excess in cardiovascular events, possibly reflecting unrecognised fluid retention with potent agonists of the PPARγ receptor. Newer pan agonists, which retain their anti-atherosclerotic activity without weight gain, may provide one solution to this problem. However, the complex biologic effects of the PPARs may mean that only vascular targeted agents or pure transrepressors will realise the goal of preventing atherosclerotic vascular disease.

    Recent evidence would indicate that high serum uric acid (SUA) levels can be a significant and independent risk factor for hypertension and cardiovascular diseases, such as ischemic heart disease and heart failure. In the last few years an independent risk relationship between hyperuricemia, cardiovascular disease and mortality has also been reported. Hyperuricemia has been shown as an independent risk factor for acute myocardial infarction and an independent and conjoint association of either gout and SUA with total and cardiovascular mortality has been reported, with mortality impact in gout patients increasing with rising SUA concentrations, even for SUA levels in the normal to high range. These findings prompted a growing research interest on the possible benefits of uric acid lowering drugs in cardiovascular diseases. Indeed, clinical studies have reported on the beneficial effects of uric acid lowering drugs, in particular of xanthine oxidase inhibitors, in hypertension, ischemic heart disease and heart failure. Two main mechanisms have been claimed to explain the dangerous effects of hyperuricemia and, as a consequence, the benefits of uric acid lowering therapy: endothelial dysfunction and systemic inflammation. This brief review aims to summarize current evidence from human studies on the role of acid uric lowering therapy in cardiovascular diseases for practical and clinical purposes. The possible mechanisms underlying the benefits of acid uric lowering therapy are also addressed. PMID:26386814

  10. Risk of cardiovascular disease following radiation exposure

    International Nuclear Information System (INIS)

    Excess radiation-induced cardiac mortalities have been reported among radiotherapy patients. Many case reports describe the occurrence of atherosclerosis following radiotherapy for Hodgkin's disease and breast cancer. Some case reports describe the cerebral infarction following radiotherapy to neck region, and of peripheral vascular disease of the lower extremities following radiotherapy to the pelvic region. The association of atomic bomb radiation and cardiovascular disease has been examined recently by incidence studies and prevalence studies of various endpoints of atherosclerosis; all endpoints indicated an increase of cardiovascular disease in the exposed group. It is almost certain that the cardiovascular disease is higher among atomic bomb survivors. However, since a heavy exposure of 10-40 Gy is delivered in radiotherapy and the bomb survivors were exposed to radiation at high dose and dose-rate, the question is whether the results can be extrapolated to individuals exposed to lower levels of radiation. Some recent epidemiological studies on occupationally exposed workers and population living near Chernobyl have provided the evidence for cardiovascular disease being a significant late effect at relatively low doses of radiation. However, the issue of non-cancer mortality from radiation is complicated by lack of adequate information on doses, and many other confounding factors (e.g., smoking habits or socio-economic status). This presentation will evaluate possible radiobiological mechanisms for radiation-induced cardiovascular disease, and will address its relevance to radiation protection management at low doses and what the impact might be on future radiation risk assessments.

    Full Text Available Abstract Although diabetes mellitus is predominantly a metabolic disorder, recent data suggest that it is as much a vascular disorder. Cardiovascular complications are the leading cause of death and disability in patients with diabetes mellitus. A number of recent reports have emphasized that many patients already have atherosclerosis in progression by the time they are diagnosed with clinical evidence of diabetes mellitus. The increased risk of atherosclerosis and cardiovascular complications in diabetic patients is related to the frequently associated dyslipidemia, hypertension, hyperglycemia, hyperinsulinemia, and endothelial dysfunction. The evolving knowledge regarding the variety of metabolic, hormonal, and hemodynamic abnormalities in patients with diabetes mellitus has led to efforts designed for early identification of individuals at risk of subsequent disease. It has been suggested that insulin resistance, the key abnormality in type II diabetes, often precedes clinical features of diabetes by 5–6 years. Careful attention to the criteria described for the cardiovascular dysmetabolic syndrome should help identify those at risk at an early stage. The application of nonpharmacologic as well as newer emerging pharmacologic therapies can have beneficial effects in individuals with cardiovascular dysmetabolic syndrome and/or diabetes mellitus by improving insulin sensitivity and related abnormalities. Early identification and implementation of appropriate therapeutic strategies would be necessary to contain the emerging new epidemic of cardiovascular disease related to diabetes.

    2016-09-01

    Emerging evidence strongly suggests that dietary nitrate, derived in the diet primarily from vegetables, could contribute to cardiovascular health via effects on nitric oxide (NO) status. NO plays an essential role in cardiovascular health. It is produced via the classical L-arginine-NO-synthase pathway and the recently discovered enterosalivary nitrate-nitrite-NO pathway. The discovery of this alternate pathway has highlighted dietary nitrate as a candidate for the cardioprotective effect of a diet rich in fruit and vegetables. Clinical trials with dietary nitrate have observed improvements in blood pressure, endothelial function, ischemia-reperfusion injury, arterial stiffness, platelet function, and exercise performance with a concomitant augmentation of markers of NO status. While these results are indicative of cardiovascular benefits with dietary nitrate intake, there is still a lingering concern about nitrate in relation to methemoglobinemia, cancer, and cardiovascular disease. It is the purpose of this review to present an overview of NO and its critical role in cardiovascular health; to detail the observed vascular benefits of dietary nitrate intake through effects on NO status as well as to discuss the controversy surrounding the possible toxic effects of nitrate.

    Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurobiological disorder exhibited by difficulty maintaining attention, as well as hyperactivity and impulsive behavior. Central nervous system (CNS) stimulants are the first line of treatment for ADHD. With the increase in number of adults on CNS stimulants, the question that arises is how well do we understand the long-term cardiovascular effects of these drugs. There has been increasing concern that adults with ADHD are at greater risk for developing adverse cardiovascular events such as sudden death, myocardial infarction, and stroke as compared to pediatric population. Cardiovascular response attributed to ADHD medication has mainly been observed in heart rate and blood pressure elevations, while less is known about the etiology of rare cardiovascular events like acute myocardial infarction (AMI), arrhythmia, and cardiomyopathy and its long-term sequelae. We present a unique case of AMI in an adult taking Adderall (mixed amphetamine salts) and briefly discuss the literature relevant to the cardiovascular safety of CNS stimulants for adult ADHD.

    Full Text Available Oxidative stress and inflammation are established processes contributing to cardiovascular disease caused by atherosclerosis. However, antioxidant therapies tested in cardiovascular disease such as vitamin E, C and β-carotene have proved unsuccessful at reducing cardiovascular events and mortality. Although these outcomes may reflect limitations in trial design, new, more potent antioxidant therapies are being pursued. Astaxanthin, a carotenoid found in microalgae, fungi, complex plants, seafood, flamingos and quail is one such agent. It has antioxidant and anti-inflammatory effects. Limited, short duration and small sample size studies have assessed the effects of astaxanthin on oxidative stress and inflammation biomarkers and have investigated bioavailability and safety. So far no significant adverse events have been observed and biomarkers of oxidative stress and inflammation are attenuated with astaxanthin supplementation. Experimental investigations in a range of species using a cardiac ischaemia-reperfusion model demonstrated cardiac muscle preservation when astaxanthin is administered either orally or intravenously prior to the induction of ischaemia. Human clinical cardiovascular studies using astaxanthin therapy have not yet been reported. On the basis of the promising results of experimental cardiovascular studies and the physicochemical and antioxidant properties and safety profile of astaxanthin, clinical trials should be undertaken.

  15. Cardiovascular Nursing: From Florence to Melbourne.

    2016-08-01

    This paper, based on the 2015 CSANZ Cardiovascular Nursing Lecture, takes its title from the invitation to give this lecture in Melbourne being received when the author was visiting Florence, after whom Florence Nightingale, the founder of modern nursing, is named. Her work has indirectly shaped and influenced cardiovascular nursing, which has developed over the past 50 years. Despite its relatively short history, cardiovascular nursing has made a major contribution to improving the cardiovascular health and well-being of patients and families through health promotion, risk reduction and disease prevention. Examples include cardiac rehabilitation and secondary prevention and chronic heart failure disease management. Challenges, however, remain, including nurses practising to the full extent of their education and training, working as full partners with physicians and other health professionals in redesigning healthcare, ensuring better data collection and being more active in advocacy and policy initiatives. Cardiovascular nursing has a strong record of innovation but should always remember that it is there to serve the public and, bearing in mind the risk of potential harm versus benefit, be mindful of Florence Nightingale's wise counsel, "First, do no harm".

    While overt vitamin B6 deficiency is not a frequent finding nowadays in medical practice, evidence suggests that insufficiency of this vitamin is rather widespread in a quite large portion of the population such as the elderly or in not unusual conditions such as that of alcohol addiction. Moreover, a mild deficiency in B6 vitamin is a state that may be associated with an increased risk of cardiovascular disease. Epidemiologic evidence from case control and prospective studies have suggested that low dietary intake or reduced blood concentrations of vitamin B6 is associated with an increased risk of cardiovascular disease, although most recent trials demonstrated the ineffectiveness of vitamin B6 supplementation on the prevention of cardiovascular events recurrence. Due to limited and somewhat inconsistent data together with the ample variety of critical functions in which vitamin B6 is involved in the human body, it is very challenging to attempt at establishing a cause and effect relationship between vitamin B6 and risk of cardiovascular disease as it is to delineate the exact mechanism(s) by which vitamin B6 may modulate such risk. In the present chapter we review the currently available knowledge deriving from both epidemiological and mechanistic studies designed to define potential candidate mechanisms for the association of vitamin B6 impairment and risk of cardiovascular disease development.

    Full Text Available Abstract Background Cardiovascular disease (CVD is the major cause of death after renal transplantation. Not only conventional CVD risk factors, but also transplant-specific risk factors can influence the development of CVD in kidney transplant recipients. The main objective of this study will be to determine the incidence of post-transplant CVD after renal transplantation and related factors. A secondary objective will be to examine the ability of standard cardiovascular risk scores (Framingham, Regicor, SCORE, and DORICA to predict post-transplantation cardiovascular events in renal transplant recipients, and to develop a new score for predicting the risk of CVD after kidney transplantation. Methods/Design Observational prospective cohort study of all kidney transplant recipients in the A Coruña Hospital (Spain in the period 1981-2008 (2059 transplants corresponding to 1794 patients. The variables included will be: donor and recipient characteristics, chronic kidney disease-related risk factors, pre-transplant and post-transplant cardiovascular risk factors, routine biochemistry, and immunosuppressive, antihypertensive and lipid-lowering treatment. The events studied in the follow-up will be: patient and graft survival, acute rejection episodes and cardiovascular events (myocardial infarction, invasive coronary artery therapy, cerebral vascular events, new-onset angina, congestive heart failure, rhythm disturbances and peripheral vascular disease. Four cardiovascular risk scores were calculated at the time of transplantation: the Framingham score, the European Systematic Coronary Risk Evaluation (SCORE equation, and the REGICOR (Registre Gironí del COR (Gerona Heart Registry, and DORICA (Dyslipidemia, Obesity, and Cardiovascular Risk functions. The cumulative incidence of cardiovascular events will be analyzed by competing risk survival methods. The clinical relevance of different variables will be calculated using the ARR (Absolute Risk

    Endothelial dysfunction has been associated with the development of atherosclerosis and cardiovascular diseases. Adult endothelial progenitor cells(EPCs) are derived from hematopoietic stem cells and are capable of forming new blood vessels through a process of vas-culogenesis. There are studies which report correlations between circulating EPCs and cardiovascular risk fac-tors. There are also studies on how pharmacotherapies may influence levels of circulating EPCs. In this review, we discuss the potential role of endothelial progenitor cells as both diagnostic and prognostic biomarkers. In addition, we look at the interaction between cardio-vascular pharmacotherapies and endothelial progenitor cells. We also discuss how EPCs can be used directly and indirectly as a therapeutic agent. Finally, we evalu-ate the challenges facing EPC research and how these may be overcome.

    Full Text Available Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Despite considerable advances in cardiovascular pharmacology, significant inter-individual variability in response to drugs affects both their efficacy and safety profile. Drug-gene associations have emerged as important factors determining a spectrum of response to therapy. Pharmacogenomic interactions in cardiovascular medicine are also involved in etiology of adverse effects that may be life-threatening, such as statininduced myopathy or a hemorrhage/thrombosis event during anticoagulant therapy. Introduction of genetic tests prior to the initiation of therapy and implementation of genetically-guided therapy represent a step forward to achieving a goal of individualized medicine in cardiology, already present in recommendations for warfarin and clopidogrel. However, further investigations addressing genomic predictors of variability in response to drugs are still needed and translating these findings into routine clinical practice remains a substantial challenge.

    Primary prevention of cardiovascular disease is a choice of great relevance because of its impact on health. Some biomarkers, such as microparticles derived from different cell populations, have been considered useful in the assessment of cardiovascular disease. Microparticles are released by the membrane structures of different cell types upon activation or apoptosis, and are present in the plasma of healthy individuals (in levels considered physiological) and in patients with different pathologies. Many studies have suggested an association between microparticles and different pathological conditions, mainly the relationship with the development of cardiovascular diseases. Moreover, the effects of different lipid-lowering therapies have been described in regard to measurement of microparticles. The studies are still controversial regarding the levels of microparticles that can be considered pathological. In addition, the methodologies used still vary, suggesting the need for standardization of the different protocols applied, aiming at using microparticles as biomarkers in clinical practice.

    2015-01-01

    Cardiolipin (CL), the signature phospholipid of mitochondrial membranes, is crucial for both mitochondrial function and cellular processes outside of the mitochondria. The importance of CL in cardiovascular health is underscored by the life-threatening genetic disorder Barth syndrome (BTHS), which manifests clinically as cardiomyopathy, skeletal myopathy, neutropenia, and growth retardation. BTHS is caused by mutations in the gene encoding tafazzin, the transacylase that carries out the second CL remodeling step. In addition to BTHS, CL is linked to other cardiovascular diseases (CVDs), including cardiomyopathy, atherosclerosis, myocardial ischemia-reperfusion injury, heart failure, and Tangier disease. The link between CL and CVD may possibly be explained by the physiological roles of CL in pathways that are cardioprotective, including mitochondrial bioenergetics, autophagy/mitophagy, and mitogen activated protein kinase (MAPK) pathways. In this review, we focus on the role of CL in the pathogenesis of CVD as well as the molecular mechanisms that may link CL functions to cardiovascular health. PMID:26301254

To prevent and control of this problem, several main risk factors needed to be known and shall be reexamined and ranked according to the priority. The objectives of this research paper was to identify several dominant risk factor related to cardiovascular problem. A cross sectional study was carried out from March 2000 – June 2001 on a total of 8159 rural population aged 18 and above to measure the prevalence of the common cardiovascular risk factors. Those risk factors are systolic blood pressure, diastolic blood pressure, serum cholesterol level, obesity index, blood glucose level, smoking, physical activity and mental stress. Overall prevalence of common cardiovascular risk factors were higher, dominated by physical inactivity (65.7%, hypercholesterolemia – TC:HC (62.3%, mental stress (55.5% and obesity (53.7%. Smoking was also high at 49.9% especially among men. However systolic hypertension, diastolic hypertension and diabetes mellitus; although increased by age, its prevalence is relatively low at 23.7%, 19.2%, and 6.3% respectively. Cardiovascular risk factors related to lifestyle are much evidenced as compared to risk factors related to the biological influence. Therefore, all initiatives in community health intervention should be mobilized specifically on prevention and control of lifestyle-related risk factors.

    Sedentary lifestyle and overweight are major public health, clinical, and economical problems in modern societies. The worldwide epidemic of excess weight is due to imbalance between physical activity and dietary energy intake. Sedentary lifestyle, unhealthy diet, and consequent overweight and obesity markedly increase the risk of cardiovascular diseases. Regular physical activity 45-60 min per day prevents unhealthy weight gain and obesity, whereas sedentary behaviors such as watching television promote them. Regular exercise can markedly reduce body weight and fat mass without dietary caloric restriction in overweight individuals. An increase in total energy expenditure appears to be the most important determinant of successful exercise-induced weight loss. The best long-term results may be achieved when physical activity produces an energy expenditure of at least 2,500 kcal/week. Yet, the optimal approach in weight reduction programs appears to be a combination of regular physical activity and caloric restriction. A minimum of 60 min, but most likely 80-90 min of moderate-intensity physical activity per day may be needed to avoid or limit weight regain in formerly overweight or obese individuals. Regular moderate intensity physical activity, a healthy diet, and avoiding unhealthy weight gain are effective and safe ways to prevent and treat cardiovascular diseases and to reduce premature mortality in all population groups. Although the efforts to promote cardiovascular health concern the whole population, particular attention should be paid to individuals who are physically inactive, have unhealthy diets or are prone to weight gain. They have the highest risk for worsening of the cardiovascular risk factor profile and for cardiovascular disease. To combat the epidemic of overweight and to improve cardiovascular health at a population level, it is important to develop strategies to increase habitual physical activity and to prevent overweight and obesity in

    Full Text Available A cardiovascular health survey of 1203 persons in households located near the hazardous waste disposal sites and in a reference community, was conducted from 2009 until today to assess whether rates of adverse cardiovascular health outcomes were elevated among persons living near the sites. Data included medical records of reported cardiovascular disease certificates and hospital admission for cardiovascular diseases from hospital database. The study areas appeared similar with respect to mortality, cancer incidence, and pregnancy outcomes. In contrast, rate ratios were greater than 1.5 for 2 of 19 reported diseases, i.e., angina pectoris, and strokes. The apparent broad-based elevation in reported diseases and symptoms may reflect increased perception or recall of conditions by respondents living near the sites. Our study found that cardiovascular risk is associated only with PM2.5 concentrations, derived from uncontrolled burning of municipal solid waste in particular sites of our country. Their analysis demonstrated a relationship between increased levels of eventual fine particulate pollution and higher rates of death and complications from cardiovascular and cerebrovascular diseases. Management of solid waste releases a number of toxic substances, most in small quantities and at extremely low levels. Because of the wide range of pollutants, the different pathways of exposure, long-term low-level exposure, and the potential for synergism among the pollutants, concerns remain about potential health effects but there are many uncertainties involved in the assessment. Future community-based health studies should include medical and psychosocial assessment instruments sufficient to distinguish between changes in health status and effects of resident reporting tendency.

    Full Text Available Hyperhomocysteinemia (Hhcy is a medical condition characterized by abnormally large levels of homocysteine in blood. The involvement of homocysteine (Hcy in various biochemical reactions causes deficiencies of the vitamins like pyridoxine (B6, folic acid (B9, or B12 leading to higher Hcy levels. Hhcy has been considered as an independent risk factor for various cardiovascular diseases like endothelial dysfunction, vascular inflammation, atherosclerosis, hypertension, cardiac hypertrophy and heart failure. The review article critically explains about the mechanisms involved in the Hhcy-induced development and progression of various cardiovascular disorders

    Hypothyroidism presenting with classic signs and symptoms is generally easily recognized. Less often, patients with hypothyroidism may present with symptoms and laboratory abnormalities suggestive of cardiovascular disease. In this article, we describe six such patients. Hypothyroidism was suspected when creatine phosphokinase (CPK) levels were persistently elevated. The diagnosis was confirmed by thyroid function tests, and thyroid hormone therapy resulted in resolution of symptoms and CPK elevations. Persistently elevated CPK levels associated with cardiovascular symptoms but without demonstrable myocardial damage should prompt consideration of covert hypothyroidism. PMID:1951418

  3. Impact of obesity on cardiovascular disease.

    LENUS (Irish Health Repository)

    Zalesin, Kerstyn C

    2012-02-01

    Obesity promotes a cascade of secondary pathologies including diabetes, insulin resistance, dyslipidemia, inflammation, thrombosis, hypertension, the metabolic syndrome, and OSA, which collectively heighten the risk for cardiovascular disease. Obesity may also be an independent moderator of cardiac risk apart from these comorbid conditions. Rates of obesity and cardiac disease continue to rise in a parallel and exponential manner. Because obesity is potentially one of the most modifiable mediators of cardiovascular morbidity and mortality, effective treatment and prevention interventions should have a profound and favorable impact on public health.

    The increased cardiovascular risk in some dermatological diseases has been demonstrated in recent decades. Diseases such as psoriasis and systemic lupus erythematosus are currently included in the guidelines for prevention of cardiovascular disease. Other diseases such as androgenic alopecia, polycystic ovary syndrome, hidradenitis suppurativa or lichen planus have numerous studies that point to an increased risk, however, they have not been included in these guidelines. In this article we review the evidence supporting this association, in order to alert the clinician to the need for greater control in cardiovascular risk factors in these patients. PMID:26383179

    Full Text Available El objetivo del presente estudio fue evaluar el efecto de una inyección de norgestomet en la dinámica folicular de vacas Cebú x Holstein sincronizadas con implantes de norgestomet. Se utilizaron 50 vacas en lactación con más de 60 días posparto, las cuales recibieron un implante de 3 mg de norgestomet y una dosis luteolítica de PGF2a (día cero. El día cinco, a 25 vacas (grupo Norg, se les administraron 1.8 mg de norgestomet intramuscular (IM y 25 vacas (grupo testigo, recibieron 3 ml de solución salina. El noveno día se retiró el implante, se realizó un destete temporal por 72 h y los animales fueron divididos al azar dentro de sus tratamientos para recibir (n = 23 o no (n = 27 500 UI de eCG. Posteriormente, las vacas fueron observadas durante cinco días en forma continua para la detección de signos de estro. Se realizaron diariamente ecografías de los ovarios desde el día de la inserción del implante hasta la presentación de estro. El tratamiento agudo con norgestomet provocó recambio del folículo dominante (FD en 40% (10/25 de las vacas, contra 16% (4/25 del grupo testigo (P 0.05 el porcentaje de vacas que presentaron estro ni el tiempo de presentación del mismo. Se concluye que el tratamiento agudo con norgestomet, durante la sincronización del estro con progestágenos, provoca atresia y recambio folicular. Sin embargo, este efecto depende de la etapa de desarrollo del folículo dominante al momento del tratamiento.

    Full Text Available La nefropatía inducida por contraste (NIC es una de las causas más frecuentes de insuficiencia renal en pacientes internados. En el síndrome coronario agudo (SCA, la presencia de NIC aumenta la morbimortalidad. Las medidas de profilaxis y los factores de riesgo intervinientes de NIC en SCA no han sido determinados con exactitud. El objetivo de este estudio fue evaluar la incidencia de NIC y los factores asociados a su desarrollo en pacientes ingresados en unidad coronaria con requerimiento de cinecoronariografía (CCG. Se realizó un estudio de cohorte retrospectivo. Se incluyeron pacientes consecutivos cursando SCA estudiados con CCG dentro de las 72 horas de su admisión. Se definió NIC al aumento del 25% del valor de creatinina a las 48 h sobre el nivel basal de ingreso. El período de inclusión fue entre el 1° de enero de 2004 hasta el 30 de junio de 2010. Se analizaron 125 casos. La incidencia de NIC fue del 10.4% (n = 13. En el análisis multivariado, los factores asociados independientemente a su desarrollo fueron la edad [OR 1.05 (IC 95% 1.004 - 1.11 p = 0.034], la angioplastia a múltiple vaso [OR 2.2 (IC 95% 1.07 - 4.8, p = 0.03] y el volumen de contraste utilizado [OR 1.007 (IC 95% 1.001 - 1.01, p = 0.014].Contrast induced nephropathy (CIN is one of the most frequent causes of acute renal failure in hospitalized patients. It is associated with an increase in morbidity and mortality in patients hospitalized for acute coronary syndrome (ACS undergoing percutaneous coronary intervention (PCI. Risk factors and prevention strategies are not well defined. The aim of this study was to assess the incidence and clinical risk factors associated to the development of contrast induced nephropathy in patients hospitalized for ACS. In a retrospective cohort we analyzed consecutive patients hospitalized for ACS undergoing urgent PCI within 72 hours from the admission. CIN was defined as a 25% increase of creatinine levels from baseline at 48

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A patogênese da síndrome do desconforto respiratório agudo (SDRA tem sido explicada pela presença de uma agressão direta (SDRA pulmonar e/ou indireta (SDRA extrapulmonar ao parênquima pulmonar. Evidências indicam que a fisiopatologia da doença pode diferir com o tipo de lesão. O objetivo deste estudo foi apresentar breve revisão das diferenças entre a SDRA pulmonar e a SDRA extrapulmonar e discutir as interações entre os aspectos morfofuncionais e a resposta aos diferentes tratamentos. CONTEÚDO: Esta revisão bibliográfica baseou-se em uma pesquisa sistemática de artigos experimentais e clínicos sobre SDRA incluídos nas bases de dados MedLine e SciElo nos últimos 20 anos. Muitos pesquisadores concordam, com base em estudos experimentais, que a SDRA pulmonar e a SDRA extrapulmonar não são idênticas no que diz respeito aos aspectos morfofuncionais, a resposta à pressão positiva ao final da expiração (PEEP, manobra de recrutamento alveolar, posição prona e outras terapias farmacológicas. Entretanto, os estudos clínicos têm descrito resultados contraditórios, os quais podem ser atribuídos à dificuldade de se classificar a SDRA em uma ou outra etiologia, e de se precisar o início, a fase e a gravidade da SDRA nos pacientes. CONCLUSÕES: Pacientes com SDRA de etiologias distintas perduram sendo considerados como pertencendo a uma mesma síndrome e, assim, são tratados da mesma forma. Logo, é fundamental entender as diferenças fisiopatológicas entre a SDRA pulmonar e extrapulmonar para que a terapia seja mais bem direcionada.BACKGROUND AND OBJECTIVES: The pathogenesis of acute respiratory distress syndrome (ARDS has been described by the presence of direct (pulmonary and/or indirect (extrapulmonary insult to the lung parenchyma.

    Full Text Available El mal agudo de montaña (MAM es un conjunto de síntomas inespecíficos padecidos por sujetos que ascienden rápidamente desde baja a alta altura sin adecuada aclimatación. Usualmente es autolimitado, pero las formas graves (edema pulmonar y cerebral pueden causar la muerte. La hipoxemia exagerada en reposo está relacionada con el desarrollo de MAM pero su valor predictivo es limitado. Dado que el ejercicio en altura se acompaña de mayor hipoxemia y síntomas, postulamos el valor predictivo de un simple test de ejercicio para pronosticar MAM grave. Se estudió el valor predictivo de la saturación de oxígeno en reposo y ejercicio submáximo a 2.700 m y 4 300 m en 63 sujetos que ascendían al cerro Aconcagua (6 962 m. Se consideró desaturación de oxígeno con ejercicio a una disminución = 5% respecto al reposo. Se utilizó la escala de Lake-Louise para establecer la presencia de MAM grave. Seis sujetos presentaron MAM grave (9.5% y requirieron evacuación. La saturación de oxígeno en reposo a 2.700 m no fue significativa para clasificar sujetos que luego desarrollaron MAM grave. Por el contrario, la asociación de desaturación durante el ejercicio a 2.700 m más la saturación inapropiada en reposo a 4.300 m fue significativa para clasificar a los sujetos que desarrollaron MAM grave con un valor predictivo positivo de 80% y un valor predictivo negativo del 97%. Nuestros resultados son relevantes para el montañismo y sugieren la adición de un simple test de ejercicio en la predicción del MAM grave.Acute mountain sickness (AMS is a group of non-specific symptoms, seen in subjects that ascend from low to high altitude too quickly, without allowing sufficient time to acclimatize. Usually it is self-limiting, but the severe forms (pulmonary and cerebral edema can be fatal. Exaggerated hypoxemia at rest is related to later development of AMS but its predictive value is limited.

    Full Text Available INTRODUÇÃO: Situs inversus totalis é descoberta importante para a conduta clínica cirúrgica. Corpo estranho no intestino grosso pode ocorrer devido a ingestão ou introdução anal. A perfuração intestinal é acompanhada de elevada morbidade e constitui-se em desafio aos cirurgiões. RELATO DO CASO: Paciente, masculino, 28 anos, deficiente mental, com dor e distensão abdominal há sete dias, anorexia há dois, parada de eliminação de gases e fezes, sem vômitos. Ao exame apresentava dispnéia leve, desidratação (++/4++, PA= 70X40mmHg, anictérico, abdome tenso, difusamente doloroso, distendido e hipertimpânico, ruídos hidroaéreos ausentes. A radiografia de tórax evidenciou dextroversão cardíaca, pneumoperitônio bilateral com bolha gástrica à direita. Devido ao estado geral grave e diagnóstico confirmado de abdome agudo perfurativo, realizou-se reposição hidroeletrolítica venosa e foi submetido à celiotomia exploradora, onde evidenciou-se peritonite fecalóide difusa e perfuração de cólon sigmóide por corpo estranho. Realizaram-se retirada do corpo estranho, limpeza mecânica, ampla lavagem da cavidade peritoneal, retossigmoidectomia à Hartmann e drenagem bilateral. CONCLUSÃO: Apesar de ser entidade rara, o diagnóstico de situs inversus totalis deve ser suspeitado durante o exame físico e confirmado através de exames de imagem, uma vez que as variações anatômicas podem prejudicar o desempenho clinicocirúrgico.BACKGROUND: Situs inversus totalis is an important discovery for the conduct of clinical surgery.
