    Full Text Available IntroducciónLa angina inestable (AI se clasifica en primaria (AP y secundaria (AS sobre la base de la presencia o no de causas secundarias de isquemia. Estas condiciones son frecuentes en los ancianos y podrían influir en su pronóstico.ObjetivoEl presente trabajo se llevó a cabo con el objetivo de evaluar las características clínicas y la evolución intrahospitalaria de ancianos con AI primaria y secundaria.Material y métodosSe registraron 298 ancianos (edad ≥ 75 años con diagnóstico final de AI. La muestra se dividió, según la presencia de causas secundarias de isquemia (anemia, taquicardia, hipertensión no controlada, infección, hipertiroidismo, en dos grupos: AS y AP. Secompararon antecedentes, características clínicas al ingreso, tratamientos, procedimientos y la ocurrencia de muerte y muerte o infarto en la fase intrahospitalaria. Se identificaronpredictores univariados de mala evolución.ResultadosCincuenta y dos pacientes (17,45% tenían AS y 246 (82,5% padecían AP. Los pacientes con AS eran más añosos y tenían mayores registros de tensión arterial y de frecuencia cardíaca al ingreso. El tratamiento médico, la cinecoronariografía y la revascularización se utilizaron menos en el grupo AS. La mortalidad (7,7% versus 6,9% [p = 1,00; OR (IC 95 = 1,12 (0,36-3,48] AS y AP, respectivamente y la combinación de muerte o infarto (7,7% versus 9,7%[p = 0,79; OR (CI 95 = 0,77 (0,25-2,32] AS y AP, respectivamente fueron similares. Los predictores univariados de muerte o infarto fueron infradesnivel del ST y desarrollo de insuficiencia cardíaca para ambos grupos y la refractariedad y necesidad de coronariografía y revascularización para el grupo AP. ConclusiónLa AS es una causa común de isquemia en los ancianos y, pese a que requiere un manejo diferente, orientado a su etiología, tiene un pronóstico similar al de la AP.

    Full Text Available FUNDAMENTO: Poucos estudos compararam a atividade inflamatória entre pacientes diabéticos e não-diabéticos com síndrome coronariana aguda, e ainda não foi publicado nenhum somente com portadores de angina instável (AI. OBJETIVO: Este estudo teve dois objetivos. Em primeiro lugar, comparar os níveis séricos de proteína C reativa (PCR e interleucina - 6 (IL-6 em pacientes diabéticos e não-diabéticos com angina instável (AI para determinar se a diferença na atividade inflamatória justifica o pior prognóstico nos pacientes diabéticos. Em segundo, avaliar a correlação entre os marcadores inflamatórios e o perfil metabólico em pacientes diabéticos e entre a resposta inflamatória e os desfechos hospitalares, como morte, infarto agudo do miocárdio, insuficiência cardíaca congestiva e tempo de hospitalização. MÉTODOS: Estudo de coorte prospectivo de 90 pacientes consecutivos admitidos na Unidade de Dor Torácica com angina instável. Os pacientes foram divididos em dois grupos: diabéticos e não-diabéticos. Os níveis séricos de PCR e IL-6, o perfil metabólico e a contagem de leucócitos foram obtidos na chegada ao hospital. RESULTADOS: Dos pacientes analisados, 42 (47% eram diabéticos (idade 62 ± 9 e 48 (53% não eram diabéticos (idade 63 ± 12. Não foram encontradas diferenças entre a mediana da PCR (1,78 vs. 2,23 mg/l, p = 0,74 e da IL-6 (0 vs. 0 pg/ml, p = 0,31 entre os dois grupos. Houve uma correlação positiva entre PCR e colesterol total (rs = 0, 21, p = 0, 05, PCR e colesterol LDL (r s = 0,22, p = 0,04 e PCR e contagem de leucócitos (r s = 0,32, p = 0,02 nos dois grupos. Nenhuma associação foi encontrada entre os marcadores inflamatórios e os desfechos hospitalares. CONCLUSÃO: Não encontramos diferença na atividade inflamatória entre os pacientes diabéticos e não-diabéticos com AI, o que indica que esse quadro clínico pode equilibrar a atividade inflamatória entre os dois grupos e aumentar a

Para conocer estas relaciones se empleó un diseño correlacional. Se crearon tres grupos en función de los niveles de ejecución en comprensión lectora y ortografía y se realizaron diferentes contrastes. En el total de la muestra se encontraron correlaciones significativas entre el rendimiento académico y la comprensión lectora y débiles y sin significación estadística entre las medidas ortográficas y la comprensión lectora. Con respecto al solapamiento entre ambas, el análisis por grupos confirmó que una buena ejecución en comprensión lectora no asegura un desempeño adecuado en decodificación ortográfica. En la discusión se analizan estas relaciones y sus implicaciones educativas.

    son las gonadotrofinas FSH y LH, el estradiol- y en ocasiones la prolactina-, además del cariotipo, o en su defecto, la cromatina sexual. Entre otras ayudas diagnósticas estarían las imagenológicas (ecografía pélvica, Rayos X de silla turca o tomografía computarizada de alta resolución en la misma región, carpograma y otros exámenes radiológicos, la laparoscopia o la laparotomia. En algunas oportunidades se han de realizar pruebas dinámicas para valorar los ejes de hipotálamo-hipófosis con las glándulas efectoras.

    El estudio de estos pacientes lo hacemos en el Hospital San Ignacio de Bogotá, con un equipo multidisciplinario constituido por Endocrinólogos Generales y Ginecológicos, Genetistas, Radiólogos y Patólogos. La mayoría de los casos son referidos a la Consulta de Esterilidad y Endocrinología Ginecológica donde en total se atienden entre 250 y 300 casos al año, de los cuales un 23% corresponde a pacientes con amenorrea y aproximadamente e18% a casos de amenorrea primaria. En ocasiones los pacientes son referidos a la Consulta de Endocrinología General, pero en cualquier eventualidad, el estudio lo hacemos conjuntamente.

    En cuanto a la clasificación, algunos prefieren incluir los casos de amenorrea primaria o secundaria en forma conjunta, tomando como base la presencia o ausencia de anormalidades cromosómicas; otros se basan en el fenotipo (seudohermafroditismos masculino y femenino, hipogonadismos con fenotipo femenino, hipogonadismo con virilización, amenorrea con desarrollo puberal normal, etc.. También se encuentran clasificaciones extensas que tratan de incluir todos los casos posibles. En esta presentación preferiremos hacer una división sencilla, por niveles, clasificando las amenorreas primarias en hipotálamo-hipofisiarias, gonadales, anormalidades anatómicas y las asociadas a trastornos suprarrenales o tiroideos. Otras causas podrían ser las enfermedades sistémicas debilitantes tales como diabetes

Avaliaram-se 932 pacientes adultos entre novembro de 2010 e novembro de 2011. Entre todos, 17,5% faziam consumo de risco (AUDIT ≥ 8, que foi mais frequente em homens, entre as pessoas mais jovens e aqueles sem doenças crônicas. O questionário CAGE foi positivo em 98 (10,5% pacientes, sendo mais frequente em homens. Homens, pessoas com idades ≥ 55 anos, com doenças crônicas ou com consumo alcoólico mais grave foram mais frequentemente questionadas sobre o uso do álcool (438/932; 47,8%. Homens, pessoas de 35 a 54 anos ou com consumo alcoólico mais grave foram mais frequentemente reconhecidos como alcoolistas (22/175; 12,6%. Conclui-se que o consumo do álcool é frequente entre os pacientes atendidos pelas ESF, é pouco reconhecido pelos profissionais e a minoria dos alcoolistas é orientada quanto aos seus riscos.

    1988-01-01

    Abdominal angina due to occlusive disease of the mesenteric arteries has been the to become clinically manifest only in the presence of severe disease in at least two of the following vessels: celiac, SMA, and IMA. Still, many patients who gradually develop significant two-vessel disease have few or no associated symptoms. Differences in collateral circulation and in cardiac index account for some of the clinical variation. The usual clinical manifestations include severe post-prandial pain, sitophobia (fear of eating because of the anticipated symptoms), and profound weight loss. Uncommonly, diarrhea, nausea, or vomiting may be encountered. Smoking is a common historical feature. Most series document a female predilection. Aside from occasional abdominal bruits and (more commonly) findings of peripheral vascular occlusive disease, the physical exam discloses only cachexia. But the differential diagnosis of profound weight loss is extensive. Therefore, abdominal angina has always created a diagnostic challenge. Multiple imaging modalities are often employed, and a seemingly negative evaluation often culminates in biplane aortography. The latter typically reveals stenoses and/or occlusions in at least two of the three mesenteric arteries. The authors discuss how a variety of surgical treatments, including thromboendarterectomy and bypass grafting, have evolved. Recently reported results have been excellent

    Full Text Available La transición entre etapas educativas y, en particular la que se realiza entre la Educación Infantil y la Educación Primaria, resulta un elemento clave y un reto para el adecuado desarrollo y aprendizaje de los alumnos. En el presente trabajo realizamos un acercamiento a la perspectiva que tienen estudiantes de Magisterio de Educación Infantil en relación con la continuidad entre las referidas etapas, a partir de la experiencia en su primer año de prácticas en centros educativos. Nuestro análisis se sustenta en las observaciones, reflexiones y argumentaciones efectuadas por los estudiantes en relación con cuestiones que, en torno a la continuidad, les planteamos al iniciar sus prácticas educativas, así como en las metáforas con las que sintetizaban su perspectiva al respecto. Los resultados constatan una cierta disfunción entre la importancia otorgada a la continuidad en los centros y sus prácticas cotidianas. De lo anterior se desprende la necesidad de instaurar en los centros propuestas armonizadas que faciliten una adecuada transición entre etapas.

    Full Text Available Las pizarras digitales interactivas (PDI son una innovación que en los últimos años ha ganado considerable presencia en las aulas de nuestro país. El objetivo principal de este estudio es investigar las percepciones que estudiantes y docentes de educación primaria tienen del uso de la PDI en el aula, así como los problemas a los que se enfrentan. Los hallazgos confirman que estudiantes y docentes aprueban el uso de esta nueva tecnología en la educación, siendo su uso mayor en la enseñanza de matemáticas, lengua y conocimiento del medio. El estudio muestra que los estudiantes creen que la PDI es efectiva en la mejora de diversos aspectos de su aprendizaje. La actitud positiva del docente hacia el uso de las nuevas tecnologías en la enseñanza juega un papel importante en la ejecución y el éxito del uso de la PDI. Por último, inferimos que las PDI no se emplean en todo su potencial.

    Full Text Available Pese a la gran frecuencia de problemas de salud mental entre los consultantes de atención primaria, persiste el problema de unos inadecuados diagnóstico y tratamiento. Se necesita una buena capacitación de los médicos de familia para el manejo de estos trastornos, a fin de minimizar su impacto sanitario, económico y social. Entre otros elementos, se considera relevante la cooperación con los servicios de salud mental, para la cual existen diferentes modelos. Nuestro departamento de salud inició en 2006 una colaboración estable según el modelo de enlace. Se han obtenido resultados positivos en términos de reducción de demora para las primeras visitas al especialista y de aumento de la satisfacción de los profesionales, aunque deben interpretarse con cautela. Recientemente se han acumulado evidencias sobre la utilidad del modelo colaborativo, aunque su evaluación y extrapolación son complejas. Nos proponemos ahondar en la evaluación de nuestro modelo, de manera análoga a otras iniciativas de nuestro entorno.

    Ischaemic heart disease is the leading cause of mortality and morbidity and one of the primary causes of morbidity in Spain. The variability in the clinical presentation of this condition at both primary care and emergency services level requires a careful history and a thorough physical examination. In the case presented, the main symptoms of angina and dyspnea reported in the anamnesis, and the obvious pallor in the physical examination, were the key data to identify anaemia as a cause of angina.

    Introduction Angina pectoris is the most prevalent symptomatic manifestation of ischemic heart disease, frequently leads to a poor quality of life, and is a major cause of medical resource consumption. Since the early descriptions of nitrite and nitrate in the 19th century, there has been considerable advancement in the pharmacologic management of angina. Areas covered Management of chronic angina is often challenging for clinicians. Despite introduction of several pharmacological agents in last few decades, a significant proportion of patients continue to experience symptoms (i.e., refractory angina) with subsequent disability. For the purpose of this review, we searched PubMed and Cochrane databases from inception to August 2016 for the most clinically relevant publications that guide current practice in angina therapy and its development. In this article, we briefly review the pathophysiology of angina and mechanism-based classification of current therapy. This is followed by evidence-based insight into the traditional and novel pharmacotherapeutic agents, highlighting their clinical usefulness. Expert opinion Considering the wide array of available therapies with different mechanism efficacy and limiting factors, a personalized approach is essential, particularly for patients with refractory angina. Ongoing research with novel pharmacologic modalities is likely to provide new options for management of angina. PMID:28264619

    Full Text Available En Costa Rica, la informática dejó de ser una “nueva tecnología” para ser parte cotidiana de la vida de docentes y estudiantes. Sin embargo, el valor y tipo de uso de las computadoras y otros componentes de la informática en la enseñanza-aprendizaje aún son sujeto de debate entre los teóricos de la educación. La discusión se centra en un aspecto teórico y otro práctico. El teórico: ¿debe enseñarse cómo funciona la computadora o debe enseñarse simplemente a usarla? El práctico: ¿conviene usar la informática durante las lecciones, o sólo como un complemento extra-clase? Tras consultar a 231 mujeres y hombres dedicados a la enseñanza primaria y secundaria en toda Costa Rica, se encontró que la mayoría está a favor de cómo enseñar a usar la computadora (más que cómo funciona, tanto en el aula como fuera de ella. Sin embargo, en la vida real usan la informática más en actividades administrativas que educativas, y no han aprovechado el verdadero potencial de la tecnología de la información y comunicación (TIC en educación, por lo cual no han cosechado los logros que se esperan de su uso. Es urgente entonces un giro radical en la forma en que se apoya al personal docente y en cómo se emplean realmente las computadoras en la educación primaria y secundaria de Costa Rica.

    Current therapy for stable angina includes surgical and percutaneous revascularization, which has been improved tremendously over the last decades. Smoking cessation and regular exercise are the cornerstone for prevention of further cerebrovascular events. Medical treatment includes treatment of cardiovascular risk factors and antithrombotic management, which can be a challenge in some patients. Owing to the fact the coronary revascularization is readily accessible these days in many industrialized countries, the importance of antianginal therapy has decreased over the past years. This article presents a contemporary overview of the management of patients with stable angina in the year 2015.

    It is of clinical relevance in the coronary care unit to evaluate the potential role of 201 Tl scintigraphy in patients with unstable angina. In the present chapter the authors discuss 1) the pattern of 201 Tl scintigraphy in patients with unstable angina; and 2) the potential predictive value of 201 Tl scintigraphy in identifying patients with unstable angina who have a poorer prognosis or greater tendency to subsequently develop acute myocardial infarction. All patients with unstable angina pectoris were purposely studied during the pain free period. It seemed conceivable that injecting 201 Tl during an anginal attack would result in a high percentage of scintigraphic defects and probably diminish a potential discriminative value of the method. Moreover in clinical practice the majority of patients arrive at the coronary care unit some time after the last anginal attack. If a diagnostic test performed at this time could distinguish high and low risk patients, important therapeutic decisions might be made at the earliest possible times. (Auth.)

    To evaluate the coronary circulation and myocardial perfusion dynamics, we performed left coronary digital subtraction angiography (DSA) in 35 patients with vasospastic angina. The left coronary circulation time (CCT) measured from the proximal left coronary artery to the coronary sinus was 5.77±0.86 sec, and the left epicardial conducting artery transmission time (CAT) measured from the proximal left coronary artery to the apical area was 2.65±0.82 sec in normal controls. The CCT and CAT were significantly prolonged in patients with vasospastic angina, indicating that the coronary peripheral vascular resistance is probably greater after the cessation of nitrates and Ca ++ -antagonists. After the intracoronary injection of ergonovine malate, the CCT was slightly shortened, but the apical T 1/2 was significantly prolonged in patients with vasospastic angina. This suggested that coronary vasospasm is present not only in the epicardial arteries but also in coronary arteries with peripheral resistance. These phenomena were not observed in normal controls. We performed left coronary DSA after conventional left coronary cineangiography. When the CCT exceeded 6.7 sec, we considered that the coronary circulation was significantly impaired. We concluded that the coronary DSA is very useful for evaluating abnormal coronary circulation in patients with vasospastic angina during myocardial perfusion. (author)

  11. Myocardial ischemia and angina pectoris

    International Nuclear Information System (INIS)

    Selwyn, A.P.; Fox, K.M.; Jonathan, A.; Lavender, P.; Watson, I.

    1981-01-01

    Ambulatory monitoring of ST segment changes was performed in 60 patients presenting with angina, positive ECG stress tests and coronary artery disease, 85% of ischemic ECG events were asymptomatic, 37% occurred with no increase in heart rate and 15% of episodes either lasted 20 minutes or more or fluctuated in severity. A controlled pilot study in ten patients showed depression. Radionuclide studies in 50 patients with angina and coronary artery disease have shown that stress (i.e., atrial pacing) produced different patterns of disturbed regional myocardial perfusion related to the patient's exercise capacity and eventually leading to a decrease in regional myocardial perfusion during the ischemic episode. ST segment depression appeared only after the decrease in regional myocardial perfusion. These findings combined with past research suggest that patients with angina and coronary artery disease can suffer frequent asymptomatic disturbances of the regional myocardial perfusion. The frequency of these episodes and the time course for the recovery of the metabolic consequences mean that segments of ventricular myocardium may be constantly abnormal. The relative importance of changes in coronary tone and malfunction of platelets in the diseased coronary tree needs to be examined in clinical research. Pilot studies of antiplatelet agents have shown a significant beneficial effect on episodes of ischemia occurring at night and those occurring without any increase in heart rate. The techniques and observations in these patients with coronary artery disease all suggest that acute transient regional myocardial ischemia is caused by a variety of mechnisms. Further research using objective methods is required to discover the causes of ischemia and to rationalize treatment. (orig./MG) [de

  13. Suppression of exercise-induced angina by magnesium sulfate in patients with variant angina

    International Nuclear Information System (INIS)

    Kugiyama, K.; Yasue, H.; Okumura, K.

    1988-01-01

    The effects of intravenous magnesium on exercise-induced angina were examined in 15 patients with variant angina and in 13 patients with stable effort angina and were compared with those of placebo. Symptom-limited bicycle exercise and thallium-201 myocardial scintigraphy were performed after intravenous administration of 0.27 mmol/kg body weight of magnesium sulfate and after placebo on different days. In all patients, serum magnesium levels after administration of magnesium sulfate were about twofold higher than levels after placebo. Exercise-induced angina associated with transient ST segment elevation occurred in 11 patients with variant angina receiving placebo and in only 2 of these patients receiving magnesium (p less than 0.005). On the other hand, exercise-induced angina was not suppressed by magnesium in any patient with stable effort angina. In these patients there was no significant difference in exercise duration after administration of placebo versus after administration of magnesium. The size of the perfusion defect as measured by thallium-201 scintigraphy was significantly less in patients with variant angina receiving magnesium than that in those receiving placebo (p less than 0.001), whereas it was not significantly different in patients with stable effort angina receiving placebo versus magnesium. In conclusion, exercise-induced angina is suppressed by intravenous magnesium in patients with variant angina but not in patients with stable effort angina. This beneficial effect of magnesium in patients with variant angina is most likely due to improvement of regional myocardial blood flow by suppression of coronary artery spasm

Se realizaron entrevistas en profundidad a docentes y a estudiantes repitentes de primer grado, y observaciones participantes en escuelas de San Miguel de Tucumán. El análisis de los datos se efectuó acorde a la teoría fundamentada. Se identificaron categorías y temas en las entrevistas y observaciones participantes, y se triangularon los datos para elaborar una teoría explicativa del fenómeno. Los resultados mostraron que las representaciones docentes inciden en la conformación de las representaciones de los niños repitentes y en las relaciones áulicas. Las docentes, que definieron a la educación de manera unicausal, se manifestaron favorables a la repitencia. Los estudiantes repitentes se representaron negativamente a la repitencia y a los vínculos con docentes y pares. Las interacciones áulicas evidenciaron comunicaciones unidireccionales y una aplicación desigual de normas. Esto permitía a las docentes mantener una autoimagen satisfactoria, pero influía negativamente en la de los niños repitentes. Las docentes que consideraron a la educación como un proceso complejo, definieron a la repitencia como una situación desfavorable. Las representaciones de los alumnos repitentes sobre la repitencia y las relaciones con docentes y pares aunaron aspectos negativos y positivos. Las relaciones áulicas evidenciaron comunicaciones uni y multi-direccionales y una aplicación de normas más equitativa. La autoimagen de las docentes y de los niños repitentes contenía aspectos positivos y negativos.

    Scintigraphic examination using 99m Tc-gluconate was carried out of the condition of the myocardium in 6 patients with a clinical diagnosis of angina pectoris of diverse severity. In all six cases the scan was negative. The results confirmed the previous experimental findings. 99m Tc-gluconate is thereby not suitable for the scintigraphic diagnosis of angina pectoris.

    Full Text Available Fundamentos: Las carencias en la colaboración entre Atención Primaria (AP y Salud Mental (SM constituyen un problema relevante en la atención a los pacientes con depresión. Resulta necesario analizar y evaluar los modelos de colaboración existentes para valorar su aplicabilidad en el sistema de salud español. El objetivo del presente estudio es conocer las principales características de los distintos modelos de colaboración AP-SM en la atención a los pacientes diagnosticados de depresión y la calidad de la evidencia científica acerca de su efectividad. Métodos: Meta-revisión sistemática de los estudios secundarios publicados entre 2001 y 2010 en MEDLINE, PsycINFO, Embase, LILACS, IBECS, IME y la Biblioteca Cochrane. Las revisiones se evaluaron mediante la herramienta AMSTAR. Se realizó una síntesis aproximativa de la calidad de las evidencias encontradas. Resultados: Se evaluaron 69 estudios. La variabilidad según contextos y las carencias metodológicas condicionan que la calidad de las evidencias sea en general baja o dudosa. Las estrategias más efectivas integran intervenciones de responsabilización en el seguimiento de los pacientes, rediseños en la gestión, e información y comunicación compartidas. Las meta-revisiones de estudios secundarios sobre modelos colaborativos favorecen la accesibilidad a las evidencias publicadas, pero conllevan importantes retos metodológicos. Conclusiones: La calidad de la evidencia sobre la efectividad de los modelos de colaboración AP-SM durante la atención sanitaria a las personas con depresión es predominantemente baja o dudosa y su significado y aplicabilidad son menores cuanto más se simplifica el análisis de sus componentes, procesos y circunstancias de implementación.

    Thallium-201 scintigraphy was performed during the pain free period in 98 patients with unstable angina. Scintiscans were positive in 39 patients, questionable in 27 patients and normal in 32 patients. Eighty-one patients responded favorably to treatment (group I). Seventeen patients had complicated courses (group II) and despite maximal treatment with propranolol either developed infarction (six patients) or continued to have angina necessitating coronary surgery (11 patients). In group I during the pain free period 26 of 81 patients had positive thallium-201 scans, whereas 20 patients had an abnormal ECG at that time; during angina 18 patients had transient ECG changes. In group II during the pain free period 13 of 17 patients had positive scans, whereas two patients had abnormal ECG at that time; during angina 12 patients showed transient ECG changes. The sensitivity to recognize group II was 76% for thallium-201 scintigraphy, 11% for ECG during the pain free period; 70% for ECG during angina; 94% for the combination of either positive scans or abnormal ECG. Thus, positive thallium-201 scans occur in patients with unstable angina, positive scans can be obtained during the pain free period, thallium-201 scans are more frequently positive in patients with complicated course

    Many studies show that ivabradine is effective for stable angina.This meta-analysis was performed to determine the effect of treatment duration and control group type on ivabradine efficacy in stable angina pectoris.Relevant articles in the English language in the PUBMED and EMBASE databases and related websites were identified by using the search terms "ivabradine," "angina," "randomized controlled trials," and "Iva." The final search date was November 2, 2015.Articles were included if they were published randomized controlled trials that related to ivabradine treatment of stable angina pectoris.Patients with stable angina pectoris were included.The patients were classified according to treatment duration (Angina outcomes were heart rate at rest or peak, exercise duration, and time to angina onset.Seven articles were selected. There were 3747 patients: 2100 and 1647 were in the ivabradine and control groups, respectively. The ivabradine group had significantly longer exercise duration when they had been treated for at least 3 months, but not when treatment time was less than 3 months. Ivabradine significantly improved time to angina onset regardless of treatment duration. Control group type did not influence the effect of exercise duration (significant) or time to angina onset (significant).Compared with beta-blocker and placebo, ivabradine improved exercise duration and time to onset of angina in patients with stable angina. However, its ability to improve exercise duration only became significant after at least 3 months of treatment.

    Acupuncture therapy on PC 6 (Neiguan) has a therapeutic effect on cardiac and chest ailments including angina pectoris. Additional beneficial acupuncture points are PC 4 (Ximen), HT 7 (Shenmen point), PC 7 (Daling point), PC 5 (Jianshi point), PC 3 (Quze point), CV 17 (Danzhong point), CV 6 (Qihai point), BL 15 (Xinshu point), L 20 (Pishu point), BL 17 (Geshu point), BL23 (Shenshu point), BL18 (Ganshu point), HT 5 (Tongli point), and ST36 (Zusanli point). Acupuncture not only quickly relieve the symptoms of acute angina pectoris, but also improve nitroglycerine's therapeutic effects. Therefore, it is an efficient simple therapeutic method used for emergency and for regular angina treatment. Review of studies on acupuncture therapy has shown effectiveness were between 80% to 96.2% that are almost as effective as conventional drug regimen. When compared with conventional medical treatment, the acupuncture therapy shows the obvious advantage of lacking, adverse side effects commonly associated with the Western anti-anginal drugs such as 1) Nitroglycerine (headache--63% with nitroglycerine patch and 50% with spray; syncope--4%; and dizziness--8% with patch; hypotension--4% with patch; and increased angina 2% with patch). 2) Isosorbide mononitrate (dizziness--3 to 5%; nausea/vomiting--2 to 4% and other reactions including hypotension, and syncope even with small doses). 3) Propranolol (bradycardia, chest pain, hypotension, worsening of AV conduction disturbance, Raynaud's syndrome, mental depression, hyperglycemia, etc.). Many conventional anti-anginal medications cause inter-drug reactions with other medications the patients taking for other diseases. Whereas, acupuncture therapy does not pose such an interference with patient's medications. Nevertheless, surgery is still the treatment of choice when acupuncture or conventional drug therapy fails. Combination of conventional drug therapy and acupuncture would considerably decrease the frequency and the required dosage

    Opinion statement Microvascular coronary dysfunction (MCD) is an increasingly recognized cause of cardiac ischemia and angina, more commonly diagnosed in women. Patients with MCD present with the triad of persistent chest pain, ischemic changes on stress testing, and no obstructive coronary artery disease (CAD) on cardiac catheterization. Data from National Heart, Lung and Blood Institute (NHLBI)-sponsored Women’s Ischemia Syndrome Evaluation (WISE) study has shown that the diagnosis of MCD is not benign, with a 2.5% annual risk of adverse cardiac events including myocardial infarction, stroke, congestive heart failure, or death. The gold standard diagnostic test for MCD is an invasive coronary reactivity test (CRT), which uses acetylcholine, adenosine, and nitroglycerin to test the endothelial dependent and independent, microvascular and macrovascular coronary function. The CRT allows for diagnostic and treatment options as well as further risk stratifying patients for future cardiovascular events. Treatment of angina and MCD should be aimed at ischemia disease management to reduce risk of adverse cardiac events, ameliorating symptoms to improve quality of life, and to decrease the morbidity from unnecessary and repeated cardiac catheterization in patients with open coronary arteries. A comprehensive treatment approach aimed at risk factor managment, including lifestyle counseling regarding smoking cessation, nutrition and physical activity should be initiated. Current pharmacotherapy for MCD can include the treatment of microvascular endothelial dysfunction (statins, angiotensin-converting enzyme inhibitor, low dose aspirin), as well as treatment for angina and myocardial ischemia (beta blockers, calcium channel blockers, nitrates, ranolazine). Additional symptom management techniques can include tri-cyclic medication, enhanced external counterpulsation, autogenic training, and spinal cord stimulation. While our current therapies are effective in the treatment

    Angina pectoris is the consequence of an inequality between the demand and supply of blood to the heart. Angina manifests itself as chest pain or discomfort and is a common complaint of patients in the hospital and in the clinic. There are, in fact, roughly half a million new cases of angina per year. Chest pain, while having many etiologies, is generally considered to be most lethal when related to a cardiac cause. In this review, the authors outline the current medical and surgical therapies that are used in the management of angina. Highlights of the various clinical trials that have assisted in the investigation of these therapies are summarized also. Then, the authors provide a focused review of the novel therapy options for angina that are currently being explored. From new medical treatments to revised surgical techniques to the discovery of stem cell therapy, many innovative options are being investigated for the treatment of angina.

Pretende responder a la cuestión de si las directrices que rigen las actuaciones en torno a la lectura de las bibliotecas escolares de Bizkaia, en el País Vasco, son convenientes y fructíferas. Con este objetivo, primero se ha realizado un análisis detallado de los hábitos lectores y las percepciones sobre la importancia de la lectura que tienen los escolares y sobre quién los induce. Posteriormente hemos elaborado un estudio diagnóstico de las bibliotecas de centros de Educación Primaria, analizando su trabajo como agente lector y su integración e implicación con la comunidad educativa. Y finalmente se ha establecido la relación de los dos análisis anteriores para ver hasta qué punto la existencia de una biblioteca escolar favorece o no los hábitos lectores, concluyendo, por una parte, que la actitud y el estímulo familiar son elementos básicos para favorecer los hábitos lectores y, por otra, que la mera presencia de una biblioteca escolar en el centro no es suficiente para mejorar hábitos o valoración de la lectura, sino que la clave está en el tipo de biblioteca que trabaja con los escolares.

    We evaluated the usefulness of hyperventilation myocardial scintigraphy (HV-SPECT) for diagnosing vasospastic angina pectoris. The subjects consisted of 11 patients with rest angina and 13 with rest and exertional angina in whom coronary spasm was demonstrated by coronary angiography, and 6 with exertional angina in whom a significant stenotic lesion was observed by coronary angiography. Hyperventilation was performed at a rate of 40/min for 5 minutes in all the patients. Ischemia was considered to be present when defect and redistribution were observed by SPECT. HV-SPECT revealed positive findings in 8 patients with rest angina (73%) and 9 with exertional and rest angina (69%) but only in 1 with exertional angina (17%). Ischemic ST changes on monitor ECG were observed in 13 of the 30 patients (43%); ST was enhanced in 4 patients and depressed in 9 patients. In the patients with rest angina, HV-SPECT induced ischemic findings more frequently than exercise SPECT (73% vs 55%). HV-SPECT seems to be useful as a non-invasive method for diagnosing angina pectoris resulting from coronary spasm. (author)

    Full Text Available La informatización de la atención primaria de salud se percibe como un problema que se soluciona creando redes computarizadas entre los consultorios y policlínicos. El artículo brinda una visión panorámica del estado en que se encuentra el arte de la informatización de la atención primaria y la medicina general integral, en el mundo y en Cuba. Para ello, se sintetiza el origen prehistórico de ese nivel de atención y de la especialidad, así como el desarrollo contemporáneo de la informática y sus aplicaciones médicas; se define igualmente la atención primaria y su informática; se resumen los sistemas de información, las aplicaciones informáticas y sus desafíos; y se ofrece una visión práctica de la historia clínica-electrónica: corazón de la informática de atención primaria de salud y medicina general integral. Se concluye que Cuba ha trabajado 20 años informatizando la dispensarización y estadísticas para la gerencia de servicios de este nivel de atención, pero que también podría trabajar con el enfoque centrado en la vida del paciente, que contribuiría a crear una clasificación integradora de la salud con la enfermedad, y a computarizar la información y la toma de decisiones clínicas en el consultorio del médico, y en el futuro hasta en el hogar del paciente, elevando directamente la calidad de la atención primaria de salud.

    Background Globally, an estimated 54 million people have angina, 16 million of whom are from the WHO South-East Asia region. Despite the increasing burden of cardiovascular disease (CVD) in South Asia, there is no evidence of an economic burden of angina on households in this region. We investigated the economic burden of angina on households in South Asia. Methods We applied a novel propensity score matching approach to assess the economic burden of angina on household out-of-pocket (OOP) health spending, borrowing or selling assets, non-medical consumption expenditure, and employment status of angina-affected individual using nationally representative World Health Survey data from Bangladesh, India, Nepal and Sri Lanka collected during 2002-2003. We used multiple matching methods to match households where the respondent reported symptomatic or diagnosed angina with control households with similar propensity scores. Results Angina-affected households had significantly higher OOP health spending per person in the four weeks preceding the survey than matched controls, in Bangladesh (I$1.94, p = 0.04), in Nepal (I$4.68, p = 0.03) and in Sri Lanka (I$1.99, p angina-affected households relative to matched controls in India (9.60%, p Angina-affected households significantly relied on borrowing or selling assets to finance OOP health expenses in Bangladesh (6%, p = 0.03), India (8.20%, p angina-affected individual remained mostly unaffected. We adjusted our estimates for comorbidities, but limitations on comorbidity data in the WHS mean that our results may be upwardly biased. Conclusions Households that had the respondent reporting angina in South Asia face an economic burden of OOP health expenses (primarily on drugs and other outpatient expenses), and tend to rely on borrowing or selling assets. Our analysis underscores the need to protect South Asian households from the financial burden of CVD. PMID:24548585

  6. The economic burden of angina on households in South Asia.

    Globally, an estimated 54 million people have angina, 16 million of whom are from the WHO South-East Asia region. Despite the increasing burden of cardiovascular disease (CVD) in South Asia, there is no evidence of an economic burden of angina on households in this region. We investigated the economic burden of angina on households in South Asia. We applied a novel propensity score matching approach to assess the economic burden of angina on household out-of-pocket (OOP) health spending, borrowing or selling assets, non-medical consumption expenditure, and employment status of angina-affected individual using nationally representative World Health Survey data from Bangladesh, India, Nepal and Sri Lanka collected during 2002-2003. We used multiple matching methods to match households where the respondent reported symptomatic or diagnosed angina with control households with similar propensity scores. Angina-affected households had significantly higher OOP health spending per person in the four weeks preceding the survey than matched controls, in Bangladesh (I$1.94, p = 0.04), in Nepal (I$4.68, p = 0.03) and in Sri Lanka (I$1.99, p finance OOP health expenses in Bangladesh (6%, p = 0.03), India (8.20%, p < 0.01) and Sri Lanka (7.80%, p = 0.01). However, impoverishment, non-medical consumption expenditure and employment status of the angina-affected individual remained mostly unaffected. We adjusted our estimates for comorbidities, but limitations on comorbidity data in the WHS mean that our results may be upwardly biased. Households that had the respondent reporting angina in South Asia face an economic burden of OOP health expenses (primarily on drugs and other outpatient expenses), and tend to rely on borrowing or selling assets. Our analysis underscores the need to protect South Asian households from the financial burden of CVD.

    Ranolazine sustained-release tablets were recently approved in the EU for chronic stable angina as add-on therapy when symptoms are not controlled with first-line agents. The mechanism of action is thought to involve inhibition of late sodium influx in the heart, which can reduce abnormalities...... of contractility and repolarisation associated with ischaemia. Ranolazine increases the exercise capacity, reduces angina, and diminishes the use of nitroglycerine. The drug has an excellent safety profile and may be a valuable addition to the treatment of chronic stable angina....

    Patients with unstable angina fall into a wide prognostic and therapeutic spectrum but, in general, have great access to specialty care and invasive procedures. In the modern era, in which admissions for unstable angina outnumber those for myocardial infarction, and growing economic pressures are placed on health care systems, cardiologists must re-examine clinical strategies for treating unstable angina in the light of health-cost accounting. The aims of the present study were to examine the current management of patients admitted to our cardiology department and to calculate the medical costs. A patient schedule was drawn up to prospectively register the number and type of cardiac processes carried out during hospitalization for all unstable angina patients in the period between March 1st and May 30th, 1995. Time (minutes) actually spent by both physicians and nurses for each cardiac process were carefully recorded in order to calculate the activity budget. The effective economic budget was built for each cardiac process taking into account salaries, consumable supplies, equipment service contracts, depreciation and indirect medical and non medical costs for CCU and ward. Based to the Diagnosis Related Groups (DRG) system, 53 out of 318 patients (16%) were admitted with documented or suspected unstable angina and allocated to discharge into four DRGs: DRG 140-medically treated unstable angina: 18 patients; DRG 124-unstable angina with angiography: 16 patients; DRG 122-unstable angina evolving in myocardial infarction: 6 patients; DRG 112-unstable angina with angioplasty: 13 patients. The mean cost for hospitalized patient with unstable angina was 5,574,958 Italian Liras (DRG 140 = 2,687,719; DRG 124 = 2,800,347; DRG 122 = 6,086,563; DRG 112 = 12,751,454). The difference in costs was essentially related to the procedures involved in medical care, DRGs with expensive cardiac processes having higher costs. Furthermore, these data show a deep discrepancy between

    Asthma is a chronic inflammatory disorder of the airways related to the obstruction of reversible airflow. Asthma presents as recurrent attacks of cough and dyspnea. Poor control causes recurrent admissions to the ICU, and mortality is related to poor drug compliance and follow-up. Angina pectoris is a syndrome of recurrent chest discomfort related to myocardial ischemia. The presence of these two disorders rarely has been reported. We reported a 12-year-old boy who was referred with exacerbation of asthma and developed angina pectoris during hospitalization. He had labored breathing and diffuse wheezing. During treatment of the asthma, the patient developed severe chest pain due to shunt formation and coronary hypoxia, caused by the sole administration of ventolin, since oxygen had been disconnected. After receiving appropriate therapy, both his asthma and angina recovered, and, to date, he has not experienced angina pectoris again.

Cada una de estas funciones se caracteriza por su alta complejidad, variada composición, el alcance de una dimensión social, elevada dinámica de realización y atributos propios. El efecto de esos procesos depende, esencialmente, de su capacidad para integrarse en un sistema armónico y coherente que requiere de la participación multidisciplinaria del sector salud, la intersectorial social y la participación comunitaria.

    Full Text Available OBJECTIVE - To determine the prevalence of hyperhomocystinemia in patients with acute ischemic syndrome of the unstable angina type. METHODS - We prospectively studied 46 patients (24 females with unstable angina and 46 control patients (19 males, paired by sex and age, blinded to the laboratory data. Details of diets, smoking habits, medication used, body mass index, and the presence of hypertension and diabetes were recorded, as were plasma lipid and glucose levels, C-reactive protein, and lipoperoxidation in all participants. Patients with renal disease were excluded. Plasma homocysteine was estimated using high-pressure liquid chromatography. RESULTS - Plasma homocysteine levels were significantly higher in the group of patients with unstable angina (12.7±6.7 µmol/L than in the control group (8.7±4.4 µmol/L (p<0.05. Among males, homocystinemia was higher in the group with unstable angina than in the control group, but this difference was not statistically significant (14.1±5.9 µmol/L versus 11.9±4.2 µmol/L. Among females, however, a statistically significant difference was observed between the 2 groups: 11.0±7.4 µmol/L versus 6.4±2.9 µmol/L (p<0.05 in the unstable angina and control groups, respectively. Approximately 24% of the patients had unstable angina at homocysteine levels above 15 µmol/L. CONCLUSION - High homocysteine levels seem to be a relevant prevalent factor in the population with unstable angina, particularly among females.

    Myocardial radiocardiography and scintigraphy with 99m Tc-pyrophosphate was performed in 58 patients with stable angina and 60 patients with unstable angina. In patients with stable angina, positive scintigrams were mostly recorded after anginal attacks. Their central hemodynamic parameters deteriorated progressively as angina increased in severity. Patients with unstable angina typically showed myocardial accumulation of the label that was unrelated to anginal attacks and recordable by direct-projection scintigraphy. The assessment of myocardial radiocardiographic and scintigraphic data allows one to differentiate between stable and unstable angina

    To evaluate the diagnostic accuracy of detection of angina-related coronary arteries in patients with unstable angina pectoris. Twenty patients with unstable angina pectoris underwent 123 I-BMIPP scintigraphy at rest. A mean duration from last anginal attack to 123 I-BMIPP scintigraphy was 4.8±3.2 days. Seventeen of 20 angina-related coronary territories were detected by reduced 123 -BMIPP uptake. The sensitivity and specificity for detection of angina-related coronary arteries were 85% and 95%, respectively. The decrease in myocardial uptake of 123 I-BMIPP agreed with the decrease in regional wall motion by using ultrasonic echocardiography. 123 I-BMIPP scintigraphy may be useful for detection of angina-related coronary artery in a routine clinical examination in patients with unstable angina pectoris.

    Tc-99m pyrophosphate (PYP) and Tl-201 simultaneous dual energy single photon emission computed tomography (SPECT) were performed in 33 patients with clinically unstable angina. According to the presence or absence of PYP accumulation in the myocardium, the patients were classified as PYP (+) group (n=22) and PYP (-) group (n=11). Clinical features, types of unstable angina, ECG changes, and serial creatine kinase (CK) data were compared in the two groups. The 'new angina at rest' type of unstable angina was more significantly common in the PYP (+) group (16/22) than the PYP (-) group (2/11). The remaining 6 patients in the PYP (+) group and 2 patients in the PYP (-) group had 'angina of effort with changing pattern'. There was a significant difference in the occurrence of ST elevation and ST depression between the group: 59% in the PYP (+) group vs. 18% in the PYP (-) group for ST elevation and 23% in the PYP (+) group vs. 64% in the PYP (-) group for ST depression. The PYP (+) group showed significant improvement in ejection fraction in the stable state (57±12%) as compared with the unstable state (62±11%), although there was no difference between the stable and unstable state in the PYP (-) group. Although wall motion abnormality index (WMI) was poorer in the PYP (+) group than the PYP (-) group, it improved to the same degree as the PYP (-) group one month later. These data suggest that the area showing PYP (+) may reflect stunned myocardium and that Tc-99m PYP accumulation may correlate with clinical features of unstable angina. (N.K.)

    Although metallic coronary stents significantly reduce angina pectoris compared with optimal medical therapy, angina after percutaneous coronary intervention (PCI) remains frequent. We, therefore, sought to compare the incidence of any angina during the 1 year after PCI among the spectrum of commercially available metallic stents. Metallic stent type was classified as bare metal stent, Cypher, Taxus Express, Xience V, Promus Element, and Resolute. The primary end point was patient-reported angina within 1 year of PCI. Multivariable logistic regression was performed to assess the independent association of stent type with any angina at 1 year. Overall, 8,804 patients were queried in regard to angina symptoms; 32.3% experienced angina at some point in the first year after PCI. Major adverse cardiovascular events, a composite of all-cause mortality, target vessel revascularization, and Q-wave myocardial infarction, increased with angina severity: 6.8% for patients without angina, 10.0% for patients with class 1 or 2 angina, and 19.7% for patients with class 3 or 4 angina (p angina at 1 year after PCI. Baseline Canadian Cardiovascular Society class 3 or 4 angina, history of coronary artery bypass grafting, and history of PCI were associated with a higher likelihood of angina at 1 year; increasing age, male gender, presentation with acute coronary syndrome, and higher stented length were associated with less angina. In conclusion, metallic stent type is not associated with the occurrence of angina at up to 1 year after PCI. Copyright © 2016 Elsevier Inc. All rights reserved.

    The authors have found that approximately one third of patients with the syndrome of unstable angina pectoris have abnormal 99mTc-pyrophosphate myocardial scintigrams even in the absence of abnormal enzymes and electrocardiographic confirmation of the presence of acute myocardial necrosis. Thus, 99mTc-pyrophosphate myocardial imaging technique appears to represent a sensitive means to detect acute multicellular injury associated with the clinical syndrome of unstable angina pectoris even when cardiac enzymes are normal and the electrocardiogram does not definitively document the presence of acute myocardial necrosis.

Este instrumento nos ha servido para analizar diferentes temas: la percepción que tienen los niños de ciclo superior sobre el bullying, en qué escenarios del centro escolar se producen más estos comportamientos, los diferentes tipos de bullying (físico, verbal y exclusión social y cuáles se producen más a menudo y analizar las respuestas que nos dan los alumnos en función del género y del curso (5.º y 6.º. Los resultados que hemos obtenido muestran, entre otras cosas: que en los niños se da más el bullying físico, mientras que en las niñas predomina el de tipo verbal y exclusión social; que la única diferencia según el curso es que en 6.º curso se da más exclusión social que en 5.º curso; y que donde se producen más conductas de bullying es en el patio, seguido del aula cuando no se encuentra el docente. Finalmente, partiendo de los resultados obtenidos, hemos elaborado unas propuestas de actuación psicopedagógicas para mejorar la convivencia en la escuela y otros espacios educativos.

    To evaluate the efficacy and safety of Ginkgo Biloba extract for patients with angina pectoris according to the available evidence. Electronic databases were searched for all of the randomized controlled trials (RCTs) of angina pectoris treatments with Ginkgo Biloba extract, either alone or combined with routine Western medicine (RWM), and controlled by untreated, placebo, Chinese patent medicine, or RWM treatment. The RCTs were retrieved from the following electronic databases: PubMed/MEDLINE, ProQuest Health and Medical Complete, Springer, Elsevier, and ProQuest Dissertations and Theses, Wanfang Data, China National Knowledge Infrastructure (CNKI), VIP database, China Biology Medicine (CBM), Chinese Medical Citation Index (CMCI), from the earliest database records to December 2012. No language restriction was applied. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. RevMan 5.1.0 provided by Cochrane Collaboration The data were analysed by using. A total of 23 RCTs (involving 2,529 patients) were included and the methodological quality was evaluated as generally low. Ginkgo Biloba extract with RWM was more effective in angina relief and electrocardiogram improvement than RWM alone. Reported adverse events included epigastric discomfort, nausea, gastrointestinal reaction, and bitter taste. Ginkgo Biloba extract may have beneficial effects on patients with angina pectoris, although the low quality of existing trials makes it difficult to draw a satisfactory conclusion. More rigorous, high quality clinical trials are needed to provide conclusive evidence.

    Full Text Available Aim. To evaluate antianginal and antiischemic efficiency of nebivolol in patients with stable angina pectoris.Material and methods. 100 patients with ischemic heart disease showing stable exertional angina pectoris and having no contraindications to beta-blockers were studied. After 5-7 days of control period 50 randomly selected patients began to take nebivolol in initial dose of 5mg once daily and 50 patients started to take metoprolol in initial dose of 50 mg twice daily. Duration of treatment was 8 weeks. Efficiency of treatment was assessed according to the results of control treadmill assessment and control daily ECG monitoring.Results. 56-day therapy with nebivolol at a dose of 7,5 mg per day results in increase in duration of treadmill test before angina or ST depression (p<0.05. Antianginal and antiischemic effect of nebivolol 7.5 mg once daily is rather similar with that of metoprolol in average daily dose of 175 mg. Nebivolol compared to metoprolol significantly (p<0.05 more effectively reduces the number of silent myocardial ischemia.Conclusion. Nebivolol is an efficient antianginal and antiischemic drug for patients with stable exertional angina pectoris.

    Cabe recordar que a raíz de la promulgación en 1978, se tejieron toda clase de versiones alrededor del significado de la estrategia planteada entonces como un paso fundamental, para un objetivo que parecía inalcanzable. En numerosos debates se hablaba de que se presentaba como una atención elemental de salud, en otros se situaba como el primer contacto de la población con la entidad de salud, en el mejor de los casos se le daba el significado de primera atención, en algunos de atención primordial, en otros de atención básica, no pocos la asimilaban a salud familiar, finalmente cuando se habló en Otawa (Canadá 1986 de la promoción y prevención como fuerzas insustituibles y el Director de la Organización Mundial de la Salud (Mahler 1986 habló de la “reacción favorable frente al fracaso de las acciones anteriores”, tomó fuerza el concepto de atención primaria como el motor insustituible para la promoción y prevención.

El propósito de este estudio es analizar los conocimientos tecnológicos, pedagógicos y disciplinares del profesorado de Educación Primaria, necesarios para la integración de las TIC en la labor docente. Para ello, se llevó a cabo una investigación con una metodología cuantitativa de carácter no experimental en la que participaron 224 profesores de Educación Infantil y Primaria de la provincia de Alicante. Los resultados mostraron que los docentes poseen mayores conocimientos pedagógicos y disciplinares que tecnológicos, lo que conlleva a escasos conocimientos para la integración de las TIC en la labor docente. Se constataron, además, diferencias significativas entre el género y los años de experiencia docente, y la relación entre el uso lúdico de la tecnología y los conocimientos sobre sus aspectos fundamentales. Según los resultados obtenidos, se corrobora la necesidad de una alfabetización digital del profesorado abordada no solo desde una formación tecnológica, sino también pedagógica y disciplinar de forma global. Ello responde al modelo TPACK (Technological, Pedagogical and Content Knowledge, el cual se contempla como un marco de referencia a tener en cuenta por lo que respecta al desarrollo profesional del profesorado y su vinculación a los procesos de enseñanza-aprendizaje en el aula donde las TIC estén presentes.

    A unique case of 'variant' angina pectoris has been observed in a patient with normal coronary arteries and typical chest pain appearing spontaneously at rest, and repeatedly provoked by ergonovine maleate (0.1 mg iv) associated with large transmural perfusion defects on 201 TI-imaging (after ergonovine) and a marked increase in T wave voltage despite no demonstrable spasm of a major coronary artery after the same doses of ergonovine. While saline solution could not provoke chest pain and treatment with a beta-blocking agent increased the frequency of ischemic attacks, a calcium antangonist therapy reduced and eventually eliminated the attacks. Thus, this case provides evidence for yet another aspect of a 'variant' form of angina pectoris: small vessel coronary artery spasm. (orig.) [de

    Drugs for erectile dysfunction (ED) may be contraindicated with nitrates commonly used to treat patients with angina pectoris, and certain antianginal therapies may worsen ED. The American Heart Association and the Princeton Consensus Conference panel of experts recommend that patients with coronary artery disease and ED who experience angina pectoris undergo full medical evaluations to assess the cardiovascular risks associated with resuming sexual activity before being prescribed therapy for ED. Current antianginal therapies include β blockers, calcium channel blockers, short- and long-acting nitrates, and ranolazine, a late sodium current inhibitor. Short- and long-acting nitrates remain a contraindication with phosphodiesterase-5 inhibitors commonly used to treat patients with ED, and the benefits of the other antianginal therapies must be weighed against their effects on cardiovascular health and erectile function. In conclusion, patients with coronary artery disease and ED who wish to initiate phosphodiesterase-5 inhibitor therapy and need to discontinue nitrate therapy need treatment options that manage their angina pectoris effectively, maintain their cardiovascular health, and provide the freedom to maintain their sexual function.

La metodología utilizada fue de tipo cualitativo. Se realizaron entrevistas en profundidad a docentes y a estudiantes repitentes de primer grado, y observaciones participantes en escuelas de San Miguel de Tucumán. El análisis de los datos se efectuó acorde a la teoría fundamentada. Se identificaron categorías y temas en las entrevistas y observaciones participantes, y se triangularon los datos para elaborar una teoría explicativa del fenómeno. Los resultados mostraron que las representaciones docentes inciden en la conformación de las representaciones de los niños repitentes y en las relaciones áulicas. Las docentes, que definieron a la educación de manera unicausal, se manifestaron favorables a la repitencia. Los estudiantes repitentes se representaron negativamente a la repitencia y a los vínculos con docentes y pares. Las interacciones áulicas evidenciaron comunicaciones unidireccionales y una aplicación desigual de normas. Esto permitía a las docentes mantener una autoimagen satisfactoria, pero influía negativamente en la de los niños repitentes. Las docentes que consideraron a la educación como un proceso complejo, definieron a la repitencia como una situación desfavorable. Las representaciones de los alumnos repitentes sobre la repitencia y las relaciones con docentes y pares aunaron aspectos negativos y positivos. Las relaciones áulicas evidenciaron comunicaciones uni y multi-direccionales y una aplicación de normas más equitativa.

    We evaluated the clinical significance of myocardial imaging using 123 I-15-(p-iodophenyl)-3-methyl pentadecanoic acid (BMIPP) scintigraphy in patients with stable effort angina pectoris (SAP) and unstable angina pectoris (UAP). Thirty-three patients with SAP were studied using rest BMIPP and stress 201 TlCl (Tl) myocardial scintigraphy, and 13 patients with worsening effort type of UAP were also examined using both rest BMIPP and Tl scintigraphy. We compared those BMIPP findings with myocardial perfusion images obtained with Tl and the regional wall motion determined by left ventriculography. In 45% of 282 segments of myocardial ischemia of SAP, the degree of myocardial uptake of BMIPP was concordant with that of stress Tl and the defect score of Tl was higher than that of BMIPP. On the other hand, in 32% of 62 segments of ischemia of UAP, the degree of myocardial BMIPP and Tl uptake was concordant and BMIPP defect score was higher than Tl score. In SAP, the decrease in regional wall motion agreed better with the decrease in myocardial uptake of BMIPP than that of Tl. These results suggest that myocardial ischemic regions decreased BMIPP uptake show the disturbance of fatty acid metabolism and lead to abnormal wall motions. Such ischemic regions may be clinically severe state in patients with angina pectoris. (author)

    The purpose of this systematic review is to assess the effectiveness of acupuncture for angina pectoris. Eleven electronic databases were searched until January 2013. The study included randomized controlled trials that the effectiveness of acupuncture alone was compared to anti-angina medicines (in addition to conventional treatment) and the effectiveness of a combination of acupuncture plus anti-angina medicines was compared to anti-angina medicines alone. The trial selection, data extraction, quality assessment and data analytic procedures outlined in the 2011 Cochrane Handbook were involved. The study included 25 randomized controlled trials (involving 2,058 patients) that met our inclusion criteria. The pooled results showed that the number of patients with ineffectiveness of angina relief was less in the combined acupuncture-anti-angina treatment group than in the anti-angina medicines alone group (RR 0.33, 95% CI 0.23-0.47, p angina medicines alone group, fewer patients in the combined treatment group showed no ECG improvement (RR 0.50, 95% CI 0.40-0.62, p angina medicines alone for both outcome measures. Only four trials mentioned adverse effects. One trial found no significant difference between acupuncture and Chinese medicine, and three reported no adverse events. The quality of the trials was found to be low. The findings showed very low evidence to support the use of acupuncture for improving angina symptoms and ECG of angina patients. However, the quality of the trials included in this study was low. Large and rigorously designed trials are needed to confirm the potential benefit and adverse events of acupuncture.

    Ambulatory monitoring of ST segment changes was performed in 60 patients presenting with angina, positive ECG stress tests and coronary artery disease, 85% of ischemic ECG events were asymptomatic, 37% occurred with no increase in heart rate and 15% of episodes either lasted 20 minutes or more or fluctuated in severity. A controlled pilot study in ten patients showed depression. Radionuclide studies in 50 patients with angina and coronary artery disease have shown that stress (i.e., atrial pacing) produced different patterns of disturbed regional myocardial perfusion related to the patient's exercise capacity and eventually leading to a decrease in regional myocardial perfusion during the ischemic episode. ST segment depression appeared only after the decrease in regional myocardial perfusion. These findings combined with past research suggest that patients with angina and coronary artery disease can suffer frequent asymptomatic disturbances of the regional myocardial perfusion. The frequency of these episodes and the time course for the recovery of the metabolic consequences mean that segments of ventricular myocardium may be constantly abnormal. The relative importance of changes in coronary tone and malfunction of platelets in the diseased coronary tree needs to be examined in clinical research. Pilot studies of antiplatelet agents have shown a significant beneficial effect on episodes of ischemia occurring at night and those occurring without any increase in heart rate. The techniques and observations in these patients with coronary artery disease all suggest that acute transient regional myocardial ischemia is caused by a variety of mechanisms. Further research using objective methods is required to discover the causes of ischemia and to rationalize treatment.

Esta es una tarea compleja y difícil ; primero porque la enseñanza de la moral requiere prescindir de referencias a cualquier clase de religión revelada y teología racional alguna y segundo porque es necesario expresar los conceptos morales en términos accesibles a los niños. Los conceptos morales se han identificado con los religiosos, pero moral y religión no son sinónimos, aquí se somete a discusión las diferencias entre ambas. Las dimensiones morales del comportamiento humano se han definido usando conceptos como "deber" "bueno" y "bien moral". En el artículo se reflexiona en torno a las relaciones entre moralidad y organización social. La enseñanza de las ideas morales debe poner en conexión la moral con algo real, por ejemplo, la condición social con la sociedad.

    In the absence of a previous global comparison, we examined the variability in the prevalence of angina across 52 countries and its association with body weight and the poverty index using data from the World Health Organization-World Health Survey. The participants with angina were defined as those who had positive results using a Rose angina questionnaire and/or self-report of a physician diagnosis of angina. The body mass index (BMI) was determined as the weight in kilograms divided by the square of the height in meters. The poverty index (a standard score of socioeconomic status for a given country) was extracted from the United Nations' statistics. The associations of angina with the BMI and poverty index were analyzed cross-sectionally using univariate and multivariate analyses. The results showed that the total participants (n = 210,787) had an average age of 40.64 years. The prevalence of angina ranged from 2.44% in Tunisia to 23.89% in Chad. Those participants with a BMI of poverty status was considered. A tendency was seen for underweight status and a poverty index >14.65% to be associated with the risk of having angina, although these associations were not statistically significant in the multilevel models. In conclusion, significant variations were found in the anginal rates across 52 countries worldwide. An increased BMI was significantly associated with the odds of having angina.

    Angina in patients with coronary artery disease is associated with worse quality of life; however, the relationship between angina frequency and resource utilization is unknown. Using data from the MERLIN-TIMI 36 trial, we assessed the association between the extent of angina after an acute coronary syndrome (ACS) and subsequent cardiovascular resource utilization among 5460 stable outpatients who completed the Seattle Angina Questionnaire at 4 months after an ACS and who were then followed for an additional 8 months. Angina frequency was categorized as none (score, 100; 2739 patients), monthly (score, 61 to 99; 1608 patients), weekly (score, 31 to 60; 854 patients), and daily (score, 0 to 30; 259 patients). Multivariable regression models evaluated the association between angina frequency and overall costs attributable to cardiovascular hospitalizations, outpatient visits and procedures, and medications. As compared with no angina, overall costs increased in a graded fashion with higher angina frequency-no angina, $2928 (reference); monthly angina, $3909 (adjusted relative cost ratio, 1.29; 95% CI, 1.21 to 1.39); weekly angina, $4558 (adjusted relative cost ratio, 1.52; 95% CI, 1.48 to 1.67); and daily angina, $6949 (adjusted relative cost ratio, 2.32; 95% CI, 2.01 to 2.69; P for trend 2-fold increase in resource utilization and incremental costs of $4000 after 8 months of follow-up.

    A previous Cochrane review has shown that exercise-based cardiac rehabilitation (CR) can benefit myocardial infarction and post-revascularisation patients. However, the impact on stable angina remains unclear and guidance is inconsistent. Whilst recommended in the guidelines of American College of Cardiology/American Heart Association and the European Society of Cardiology, in the UK the National Institute for Health and Care Excellence (NICE) states that there is "no evidence to suggest that CR is clinically or cost-effective for managing stable angina". To assess the effects of exercise-based CR compared to usual care for adults with stable angina. We updated searches from the previous Cochrane review 'Exercise-based cardiac rehabilitation for patients with coronary heart disease' by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, DARE, CINAHL and Web of Science on 2 October 2017. We searched two trials registers, and performed reference checking and forward-citation searching of all primary studies and review articles, to identify additional studies. We included randomised controlled trials (RCTs) with a follow-up period of at least six months, which compared structured exercise-based CR with usual care for people with stable angina. Two review authors independently assessed the risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. Two review authors also independently assessed the quality of the evidence using GRADE principles and we presented this information in a 'Summary of findings' table. Seven studies (581 participants) met our inclusion criteria. Trials had an intervention length of 6 weeks to 12 months and follow-up length of 6 to 12 months. The comparison group in all trials was usual care (without any form of structured exercise training or advice) or a no-exercise comparator. The mean age of participants within the trials ranged from 50 to 66 years, the

    Previous studies suggest that among patients with stable coronary artery disease, patients with diabetes mellitus (DM) have less angina and more silent ischemia when compared with those without DM. However, the burden of angina in diabetic versus nondiabetic patients after elective percutaneous coronary intervention (PCI) has not been recently examined. In a 10-site US PCI registry, we assessed angina before and at 1, 6, and 12 months after elective PCI with the Seattle Angina Questionnaire angina frequency score (range, 0-100, higher=better). We also examined the rates of antianginal medication prescriptions at discharge. A multivariable, repeated-measures Poisson model was used to examine the independent association of DM with angina over the year after treatment. Among 1080 elective PCI patients (mean age, 65 years; 74.7% men), 34.0% had DM. At baseline and at each follow-up, patients with DM had similar angina prevalence and severity as those without DM. Patients with DM were more commonly prescribed calcium channel blockers and long-acting nitrates at discharge (DM versus not: 27.9% versus 20.9% [ P =0.01] and 32.8% versus 25.5% [ P =0.01], respectively), whereas β-blockers and ranolazine were prescribed at similar rates. In the multivariable, repeated-measures model, the risk of angina was similar over the year after PCI in patients with versus without DM (relative risk, 1.04; range, 0.80-1.36). Patients with stable coronary artery disease and DM exhibit a burden of angina that is at least as high as those without DM despite more antianginal prescriptions at discharge. These findings contradict the conventional teachings that patients with DM experience less angina because of silent ischemia. © 2017 American Heart Association, Inc.

    Full Text Available Antecedentes: El trastorno depresivo mayor (TDM es una enfermedad frecuente en la población general y una de las principales causas de discapacidad en el mundo. La distinción entre los cambios que normalmente ocurren en el estado del ánimo y aquellos que están presentes en el espectro de los trastornos depresivos no es una tarea fácil, por esta razón se han propuestos varios mecanismos e instrumentos para mejorar la detección de este trastornos en la consulta de atención primaria. Objetivos: Evaluar si la detección sistemática rutinaria con instrumentos de tamizaje, con o sin sistemas de seguimiento y manejo integrado, es más efectiva que la atención usual en identificar pacientes con depresión, facilitar su tratamiento, y mejorar los resultados clínicos, a nivel de la atención primaria. Material y Métodos: Para determinar la utilidad del tamizaje sistemático para depresión a nivel de atención primaria, se llevó a cabo una búsqueda de estudios de casos y controles, cohortes y controlados aleatorizados, revisiones sistemáticas, y meta-análisis, en las bases de datos MEDLINE, Base de datos de revisiones sistemáticas Cochrane, Registro central de estudios controlados Cochrane, PsycINFO, y EMBASE, desde enero de 1976 hasta el 30 de abril de 2013. Resultados: La evidencia existente mostró que muchos casos de depresión no son detectados. Los médicos de atención primaria (MAP logran tasas de detección del trastorno depresivo entre el 30% y 40% (rango 7-70%, sin utilizar herramientas adicionales para el diagnóstico como las escalas de una, dos y tres preguntas. Los pacientes con los cuadros menos severos y más jóvenes son los menos detectados. Conclusiones: La evidencia encontrada muestra que el tamizaje para depresión a nivel de atención primaria con retroalimentación del resultado puede incrementar el reconocimiento del trastorno por parte del MAP. Sin embargo, el efecto de la retroalimentación sobre el tratamiento

    Ethnicity and smoking are well-known risk factors for the pathogenesis of coronary vasospasm. Oxidative stress induced by smoking plays a crucial role in coronary vasospasm, but is not enough to account for the pathogenesis of coronary vasospasm, indicating that genetic factors are strongly involved. The study group comprised 162 vasospastic angina patients (VSAs), 61 microvascular angina patients (MVAs) and 61 non-responders (NRs) diagnosed by acetylcholine provocation test. Four polymorphisms of the oxidative stress related genes, cytochrome b-245, alpha polypeptide gene (CYBA) C242T and A640G, paraoxonase 1 gene (PON1) A632G, phospholipase A2 group VII gene (PLA2G7) G994T were genotyped. Allele frequency of PON1 632-G was significantly higher in both the VSA with dominant fashion and the MVA with recessive fashion compared with NR. This association was strongly influenced by gender in the MVA only. There were no significant associations between the other polymorphisms and coronary vasospasm. In addition, the allele frequency of PON1 632-G in the Japanese was higher than in Caucasians. There was a significant association between PON1 A632G polymorphism and MVA as well as VSA, but the impact of this on VSA and MVA is different in the Japanese.

    Full Text Available La Atención Primaria de la Salud, un concepto amplio y difundido, es colocado en debate en el presente artículo. Sin embargo, esa es, una tarea nada sencilla, dado el fuerte carácter idealista de sus principios y postulados. A través de diversos mecanismos, como develar sus antecedentes inmediatos y remotos, la detección de modelos en conflicto, de contradicciones conceptuales y el uso extensivo de preguntas, diversas afirmaciones doctrinarias, que parecen de toda obviedad, son puestas en entredicho. Se invita así al lector/a a una 'deconstrucción' del concepto de Atención Primaria de la Salud, de cara a producir nuevas propuestas más estratégicas y eficaces para que los trabajadores de salud, donde quiera que se desempeñen, cuenten con herramientas para enfrentar la creciente mercantilización del sector.

Las actividades fueron diseñadas con un enfoque integrador y una perspectiva multidisciplinar orientada a la elaboración de propuestas de enseñanza-aprendizaje globalizadas y consistentes con las distintas áreas disciplinares involucradas en Educación Primaria. Para conocer las actitudes e ideas de los futuros maestros se utiliza un cuestionario formado por 10 preguntas abiertas y 10 ítems de escala Likert de 5 puntos. En este trabajo se analizan los resultados obtenidos en los 10 ítems. Los resultados muestran que todos los grupos presentan mejoras en su actitud hacia la enseñanza del sonido. Además, resulta destacable la reducción de las diferencias existentes inicialmente entre ellos una vez realizada la intervención. Esto nos lleva a considerar que el programa realizado ha cumplido su propósito, que llevando a cabo intervenciones con un enfoque interdisciplinar pueden mejorar significativamente la actitud en los futuros maestros, lo que resulta de interés para su futura práctica docente.

Con el fin de definir un tratamiento racional oportuno y orientar el diagnóstico molecular de las inmunodeficiencias primarias, se estableció un programa para el diagnóstico fenotípico de estas enfermedades en el departamento de Antioquia (Colombia, que comprende un análisis clínico y de laboratorio de los individuos que presentan infecciones recurrentes de evolución anormal. Entre el 1 de agosto de 1994 y el 31 de julio de 2002 se hizo el diagnóstico fenotípico de inmunodeficiencia primaria en 98 pacientes. Similar a lo informado en la literatura especializada, en esta región las deficiencias predominantes de anticuerpos fueron las más frecuentes (40,8% seguidas por las deficiencias combinadas (21,4%. Esta caracterización fenotípica ha permitido iniciar rápidamente el tratamiento adecuado y, en algunos casos, comenzar los estudios funcionales y moleculares que conduzcan al diagnóstico molecular definitivo.

Se trabajó con 60 docentes de Montevideo y zona metropolitana respondiendo el Cuestionario de Ideas de los Docentes sobre Diversidad Familiar –CIDF– (Morgado, Jiménez-Lagares & González, 2009. Los datos obtenidos refieren que los docentes no mantienen una visión homogénea de los distintos tipos de hogares. Las familias adoptivas, las de progenitores divorciados y las monoparentales bajo responsabilidad de madres tuvieron mejor aceptación entre los docentes que las homoparentales o las encabezadas en solitario por un padre. Los ítems relativos a familias homoparentales fueron respondidos por menos personas. Los docentes con formación de posgrado se mostraron más tolerantes y flexibles ante la diversidad familiar. Se discuten estos resultados a la luz de las necesarias adaptaciones en la educación primaria con respecto a la diversidad de familias que allí asisten.

Bajo el sustento de los marcos teóricos de referencia que explican ambas variables, el objetivo del estudio fue analizar las diferencias significativas existentes en la creatividad y las inteligencias múltiples entre niños y niñas de 1º de Educación primaria. La muestra se compuso de 60 estudiantes (chicos=31; chicas=29 de 6 y 7 años escolarizados en un centro público de Zaragoza. Los instrumentos utilizados fueron el Cuestionario del profesorado para diagnosticar Inteligencias Múltiples en Primaria y el Test de Pensamiento Creativo de Torrance. Los resultados mostraron diferencias significativas en la creatividad, siendo las chicas quienes obtuvieron mayores puntuaciones. Respecto a las inteligencias múltiples, la inteligencia interpersonal fue la que mayores puntuaciones obtuvo en ambos géneros. Paralelamente, la inteligencia musical fue la de menor puntuación en ambos géneros, siendo la única que mostró diferencias significativas. Estos hallazgos se discuten argumentando la necesidad de realizar un programa de intervención que potencie la creatividad y la inteligencia musical en ambos géneros a través del resto de inteligencias, significando un aprendizaje transversal que optimice la formación del alumnado de manera íntegra.

El concepto de capital social fue entendido como el resultado de la relación entre Estado y sociedad. En Rosario se lograron mejoras sustantivas en las condiciones de acceso a partir de la creación de nuevas estructuras en donde profesionales de APS establecieron vínculos de cooperación con actores del Estado municipal, movimientos sociales y gestores y médicos especialistas de hospitales. En Vicente López, las mejoras en las condiciones de acceso a los servicios de salud fueron más limitadas debido a que los cambios en la relación Estado y sociedad solo involucraron a profesionales del primer nivel de atención sin mecanismos de cooperación estables con actores claves de los hospitales, el nivel municipal y los movimientos sociales. Por último, en Cochabamba, las mejoras en las condiciones de acceso fueron marginales debido a que los profesionales del sistema de servicios de salud se opusieron a la alianza establecida entre los movimientos sociales y los actores del Estado municipal para generar cambios en el sistema de salud. Este estudio permite reconocer la influencia de la configuración entre Estado y sociedad para modelar las relaciones de poder que subyacen al proceso de implementación de las reformas del sector salud y sus resultados.

    In chronic stable angina, elevated heart rate contributes to the development of symptoms and signs of myocardial ischaemia by increasing myocardial oxygen demand and reducing diastolic perfusion time. Accordingly, heart rate reduction is a well-known strategy for improving both symptoms of myocardial ischaemia and quality of life (QOL). The heart rate-reducing agent ivabradine, a direct and selective inhibitor of the I f current, decreases myocardial oxygen consumption while increasing diastolic time, without affecting myocardial contractility or coronary vasomotor tone. Ivabradine is indicated for treatment of stable angina and chronic heart failure (HF). This review examines available evidence regarding the efficacy and safety of ivabradine in stable angina, when used as monotherapy or in combination with beta-blockers, in particular angina subgroups and in patients with stable angina with left ventricular systolic dysfunction (LVSD) or HF. Trials involving more than 45 000 patients receiving treatment with ivabradine have shown that this agent has antianginal and anti-ischaemic effects, regardless of age, sex, severity of angina, revascularisation status or comorbidities. This heart rate-lowering agent might also improve prognosis, reduce hospitalisation rates and improve QOL in angina patients with chronic HF and LVSD. PMID:29632676

    To clarify the coronary hemodynamics and myocardial perfusion in patients with vasospastic angina, we performed exercise 201 Tl-myocardial scintigraphy (planar and SPECT) in 72 patients and left coronary digital subtraction angiography (DSA) in 37 patients without significant organic coronary artery stenosis. Coronary artery spasm was documented by coronary angiography in all patients. Fifty-four patients (75%) developed exercise-induced 201 Tl-myocardial perfusion defect on SPECT. 201 Tl pulmonary uptake (L/H) was significantly increased in patients with vasospastic angina. Especially, L/H was higher in patients with multiple small perfusion defect on 201 Tl-SPECT, so that exercise-induced left ventricular dysfunction existed in patients with vasospastic angina and especially in cases of multiple small perfusion defect on 201 Tl-SPECT. The left coronary circulation time (CCT) was prolonged in patients with vasospastic angina. The mechanism of prolonged CCT is still unknown, but we suspected that prolonged CCT was induced by increased peripheral coronary vascular resistance in patients with vasospastic angina. It was concluded that the peripheral coronary circulation was disturbed in patients with vasospastic angina, but its abnormal coronary circulation had no relation to location of spasm-induced vessels. We concluded that impaired coronary microcirculation was taken a part of pathophysiology in vasospastic angina. (author)

    Angina pectoris is a common symptom imperiling patients' life quality. The aim of this study is to evaluate the efficacy and safety of acupuncture for stable angina pectoris. Clinical randomized-controlled trials (RCTs) comparing the efficacy of acupuncture to conventional drugs in patients with stable angina pectoris were searched using the following database of PubMed, Medline, Wanfang and CNKI. Overall odds ratio (ORs) and weighted mean difference (MD) with their 95% confidence intervals (CI) were calculated by using fixed- or random-effect models depending on the heterogeneity of the included trials. Total 8 RCTs, including 640 angina pectoris cases with 372 patients received acupuncture therapy and 268 patients received conventional drugs, were included. Overall, our result showed that acupuncture significantly increased the clinical curative effects in the relief of angina symptoms (OR=2.89, 95% CI=1.87-4.47, Pacupuncture therapy was superior to conventional drugs. Although there was no significant difference in overall effective rate relating reduction of nitroglycerin between two groups (OR=2.13, 95% CI=0.90-5.07, P=0.09), a significant reduction on nitroglycerin consumption in acupuncture group was found (MD=-0.44, 95% CI=-0.64, -0.24, Pacupuncture therapy than for traditional medicines (MD=2.44, 95% CI=1.64-3.24, Pacupuncture therapy were found. Acupuncture may be an effective therapy for stable angina pectoris. More clinical trials are needed to systematically assess the role of acupuncture in angina pectoris.

    The role of magnetic resonance imaging in characterizing normal, ischemic and infarcted segments of myocardium was examined in 8 patients with unstable angina, 11 patients with acute myocardial infarction, and 7 patients with stable angina. Eleven normal volunteers were imaged for comparison. Myocardial segments in short axis magnetic resonance images were classified as normal or abnormal on the basis of perfusion changes observed in thallium-201 images in 22 patients and according to the electrocariographic localization of infarction in 4 patients. T2 relaxation time was measured in 57 myocardial segments with abnormal perfusion (24 with reversible and 33 with irreversible perfusion changes) and in 25 normally perfused segments. T2 measurements in normally perfused segments of patients with acute myocardial infarction, unstable angina and stable angina were within normal range derived from T2 measurements in 48 myocardial segments of 11 normal volunteers (42 +/- 10 ms). T2 in abnormal myocardial segments of patients with stable angina also was not significantly different from normal. T2 of abnormal segments in patients with unstable angina (64 +/- 14 in reversibly ischemic and 67 +/- 21 in the irreversibly ischemic segments) was prolonged when compared to normal (p less than 0.0001) and was not significantly different from T2 in abnormal segments of patients with acute myocardial infarction (62 +/- 18 for reversibly and 66 +/- 11 for irreversibly ischemic segments). The data indicate that T2 prolongation is not specific for acute myocardial infarction and may be observed in abnormally perfused segments of patients with unstable angina

    Abstract Background: To systematically evaluate the clinical efficacy and safety of Salvianolate injection in the treatment of unstable angina pectoris (UAP). Methods: Using literature databases, we conducted a thorough and systematic retrieval of randomized controlled trials (RCTs) that using Salvianolate injection for treating UAP. The Cochrane Risk of Bias Assessment Tool was used to evaluate the methodological quality of the RCTs, and then the data were extracted and meta-analyzed by RevMan5.2 software. Results: A total of 22 RCTs with 2050 participants were included. The meta-analysis indicated that the combined use of Salvianolate injection and western medicine (WM) in the treatment of UAP can achieve a superior effect in angina pectoris total effective rate (risk ratio [RR] = 1.22, 95% confidence interval [CI] (1.17, 1.27), Z = 10.15, P < 0.00001], and the total effectiveness rate of electrocardiogram [RR = 1.26, 95% CI (1.19,1.34), Z = 7.77, P < 0.00001]. In addition, Salvianolate injection can improve the nitroglycerin withdrawal rate and the serum level of NO, decrease high-sensitivity C-reactive protein. Adverse drug reactions (ADRs) or adverse drug events (ADEs) were reported in 6 RCTs involving 15 cases; however, there were no serious ADRs/ADEs. Conclusion: Based on the systematic review, the combined use of Salvianolate injection and WM in the treatment of UAP can achieve a better effect; however, there was no definitive conclusion about its safety. More the large-sample and multicenter RCTs are needed to support its clinical usage. PMID:28002341

    An unusual case of typical angina which occurred on a long haul flight is presented. This case is notable as this was the index presentation, with no previous symptoms prior to this. Physiological changes at altitude can be marked, and include hypoxia, tachycardia and an increase in cardiac output. These changes were enough to expose underlying angina in our patient. A 68 year old man presented with typical cardiac chest pain on a long haul flight. His symptoms first started 10-15 min after take-off and resolved on landing. This was his index presentation, and there were no similar symptoms in the past. Background history included hypercholesterolaemia and benign prostatic hypertrophy only. He led a rather sedentary lifestyle. A CT coronary angiogram showed significant disease in the proximal left anterior descending artery and proximal right coronary artery. He went on to have a coronary angiogram with invasive physiological measurements, which determined both lesions were physiologically significant. Both arteries were treated with drug eluting stents. Since treatment, he once again embarked on a long haul flight, and was completely asymptomatic. The presentation of symptoms in this individual was rather unusual, but clearly caused by significant coronary artery disease. Potentially his sedentary lifestyle was not enough in day-to-day activities to promote anginal symptoms. When his cardiovascular system was physiologically stressed during flight, brought about by hypoxia, raised sympathetic tone and increased cardiac output, symptoms emerged. In turn, when landing, with atmospheric conditions normalised, physiological stress was removed, and symptoms resolved. Clinically therefore, one should not exclude symptoms that occur with differing physiological states, such as stress and altitude, as they are also potential triggers for myocardial ischaemia, despite absence of day-to-day symptoms.

    There is a group of patients with chronic refractory chest angina, who are not ideal candidates for surgical or percutaneous revascularization and who although having a good medical handling continues to experience severe episodes of angina. The spinal electrical stimulator is a neuromodulators used as an alternative to treat these patients. The objective is to realize a review of scientific literature regarding the spinal electric stimulation in the treatment of chest angina, its mechanism of action, benefits and its cost effectiveness. Materials and methods: using the Cochrane methodology, a search of articles published from January 1980 to January 2007 in Medline using the terms spinal cord stimulation, was realized. The papers considered most pertinent were selected. Conclusions: the anti-ischemic effect of the electrical spinal stimulator reduces the episodes of chest angina, improves the quality of life and the tolerance to exercise, diminishes the hospital stay and delays the appearance of ischemic signs

    We investigated the washout of 123 I-BMIPP from early and delayed SPECT in 28 patients with vasospastic angina from the standpoint of the intervals from the last angina attack. We divided myocardial wall into 13 segments from the early and delayed SPECT, and visually classified into four grades of defect score ranged from 0 (normal) to 3 (severe defect). Early and delayed severity scores were calculated as a total of defect scores in 3 vessel territories, and washout scores (WS) as (delayed severity score early severity score)/ number of segments. WS of the group within 1 month from last angina attack was compared with the groups more than 1 month. In the territory of the right coronary artery, the group within 1 month showed significantly higher WS than groups more than 1 month (p 123 I-BMIPP may reflect the clinical course of vasospastic angina.

    Variant angina pectoris, also called Prinzmetal's angina, is a syndrome caused by vasospasms of the coronary arteries. It can lead to myocardial infarction, ventricular arrhythmias, atrioventricular block and even sudden cardiac death. We report the case of a 53 year-old male patient with recurrent episodes of chest pain and arrhythmias in the course of related variant angina pectoris. It is likely that the reperfusion following myocardial ischemia was responsible for the ventricular fibrillation while the ST-segment returned to the baseline. This case showed that potential lethal arrhythmias could arise due to variant angina pectoris. It also indicated that ventricular fibrillation could be self-terminated. Copyright © 2015 Elsevier Inc.

    Myocardial thallium scintigraphy was performed in four subjects with variant angina and in one subject with isolated, fixed coronary obstruction. Three subjects with variant angina had short episodes of ischemic ST-segment elevation that lasted 20--100 seconds. Thallium scintigrams demonstrated excess uptake in regions judged to be ischemic by angiographic and electrocardiographic criteria. Two subjects, one with variant angina and the other with a fixed coronary lesion, had prolonged episodes of ischemia that lasted 390--900 seconds. Both had reduced thallium uptake in the ischemic regions. We conclude that myocardial reactive hyperemia is the cause of excess thallium uptake in patients with variant angina who have short episodes of myocardial ischemia

    /sup 99m/Technetium stannous pyrophosphate has been shown to accumulate in acutely infarcted myocardium. To determine if the isotope is also taken up by severely ischemic, but not necrotic myocardium, we performed myocardial scintigraphic studies in 17 patients with chest pains. Seven of the patients satisfied conventional clinical, electrocardiographic, and laboratory criteria for the diagnosis of unstable angina and showed no electrocardiographic or enzymatic evidence of myocardial necrosis. Five of these seven patients with unstable angina demonstrated abnormal localized patterns, and one showed a borderline picture. Myocardial scintiscans were normal in all of a control group of ten patients with stable angina. Thus, scanning with /sup 99m/technetium stannous pyrophosphate is shown to be of value in the objective demonstration of myocardial abnormality in unstable angina

    Patients with diabetes mellitus and coronary artery disease are thought to have painless myocardial ischemia more often than patients without diabetes. We studied 50 consecutive patients with diabetes and 50 consecutive patients without diabetes, all with ischemia, on exercise thallium scintigraphy to show the reliability of angina as a marker for exertional ischemia. The two groups had similar clinical characteristics, treadmill test results, and extent of infarction and ischemia, but only 7 patients with diabetes compared with 17 patients without diabetes had angina during exertional ischemia. In diabetic patients the extent of retinopathy, nephropathy, or peripheral neuropathy was similar in patients with and without angina. Angina is an unreliable index of myocardial ischemia in diabetic patients with coronary artery disease. Given the increased cardiac morbidity and mortality in such patients, periodic objective assessments of the extent of ischemia are warranted

Los participantes son 88 alumnos/as de 8-10 años de edad, de un colegio de la provincia de Málaga. Los resultados muestran que el alumnado evaluado presenta valores normalmente bajos en variables que indican inadaptación escolar y valores normativos en variables que se asocian a una buena adaptación escolar y social. Las correlaciones entre las variables predictoras y criterio muestran dos patrones diferentes: mientras que los datos de padres se asocian más activamente a las variables clima social y violencia sufrida en el caso de los profesores son prosocialidad y violencia sufrida. Los análisis de regresión demuestran también dos patrones diferentes para padres y para profesores, poniendo de manifiesto la importancia que tiene la violencia cotidiana sufrida en los resultados de adaptación o inadaptación escolar y social en alumnado que está en segundo ciclo de Educación Primaria, y la relevancia del comportamiento prosocial para predecir buenos resultados en el ámbito académico.

    Dental infections, such as periodontitis, associate with atherosclerosis and its complications. We studied a cohort followed-up since 1985 for incidence of angina pectoris with the hypothesis that calculus accumulation, proxy for poor oral hygiene, links to this symptom. In our Swedish prospective cohort study of 1676 randomly selected subjects followed-up for 26 years. In 1985 all subjects underwent clinical oral examination and answered a questionnaire assessing background variables such as socio-economic status and pack-years of smoking. By using data from the Center of Epidemiology, Swedish National Board of Health and Welfare, Sweden we analyzed the association of oral health parameters with the prevalence of in-hospital verified angina pectoris classified according to the WHO International Classification of Diseases, using descriptive statistics and logistic regression analysis. Of the 1676 subjects, 51 (28 women/23 men) had been diagnosed with angina pectoris at a mean age of 59.8 ± 2.9 years. No difference was observed in age and gender between patients with angina pectoris and subjects without. Neither was there any difference in education level and smoking habits (in pack years), Gingival index and Plaque index between the groups. Angina pectoris patients had significantly more often their first maxillary molar tooth extracted (d. 16) than the other subjects (p = 0.02). Patients also showed significantly higher dental calculus index values than the subjects without angina pectoris (p = 0.01). Multiple regression analysis showed odds ratio 2.21 (95% confidence interval 1.17-4.17) in the association between high calculus index and angina pectoris (p = 0.015). Our study hypothesis was confirmed by showing for the first time that high dental calculus score indeed associated with the incidence of angina pectoris in this cohort study.

    Ranolazine is a novel antianginal medication approved for the treatment of chronic angina. There are only limited data concerning the efficacy of ranolazine in reducing healthcare resource utilization in patients with refractory angina pectoris. The primary objective of this analysis was to evaluate the efficacy and safety of ranolazine in refractory angina pectoris. In addition, the impact of ranolazine on healthcare resource utilization was assessed. Consecutive patients with refractory angina pectoris treated with ranolazine at two cardiology practices in the state of Nebraska were included in this analysis. The Canadian Cardiovascular Society (CCS) angina class and frequency and type of healthcare resource consumption were determined during the 12 months prior to and the 12 months after initiation of ranolazine. A total of 150 pts (64 % men) with a mean age of 66 ± 12 years were included in this analysis. All patients had previously undergone coronary revascularization. Nitrates, β-adrenoceptor antagonists (β-blockers), and calcium antagonists (calcium channel blockers) were being used in 83, 97, and 75 % of patients, respectively. During ranolazine treatment, a significant improvement in CCS angina class was observed, with 23 patients improving by one class and no patient experiencing a deterioration in functional class (p = 0.025). A total of 53 side effects occurred in 28 (19 %) patients receiving ranolazine. Of those patients with side effects, four required dose reduction and seven required drug discontinuation. The frequency of clinic visits and emergency room visits was lower during ranolazine treatment, but the differences in frequency were not significant. The number of patients hospitalized and the number of hospitalizations were significantly lower during ranolazine therapy than in the pre-ranolazine study period (p = 0.002). Ranolazine improved the CCS angina class and reduced hospitalizations over a 12-month follow-up period in a group

    Due to sensorial autonomic neuropathy, the type and severity of angina pectoris in patients with diabetes mellitus (DM) may be rather different from the type and severity of angina pectoris in patients without DM. The aim of the study was to understand if angina pectoris is related to extensive coronary artery disease (CAD) in patients with DM. The study included 530 patients with DM who underwent coronary angiography at our center in 2009 and 2010. Patients were divided into 4 groups according to type of chest pain: group 1, noncardiac chest pain or no pain; group 2, angina equivalent; group 3, atypical angina; and group 4, typical angina. All angiograms were re-evaluated and Gensini scores were calculated. Three-vessel disease was diagnosed in the presence of stenosis >50% in all 3 coronary artery systems. There were no statistically significant differences between the groups with regard to age, sex, systolic or diastolic blood pressures, body mass index, creatinine clearance, or lipid profile. Fasting blood glucose was significantly higher in group 4 than in group 2. Gensini scores were not statistically different between groups 1 and 2 or between groups 3 and 4; however, the scores for groups 3 and 4 were higher than the score for either group 1 or group 2. Prevalence of 3-vessel disease was significantly higher in groups 3 and 4 compared with the other groups. The presence of angina pectoris was related to extensive CAD in patients with DM. The extent of CAD was not correlated with the type of angina (typical or atypical). © 2013 Wiley Periodicals, Inc.

    Full Text Available Richard KonesThe Cardiometabolic Research Institute, Houston, Texas, USAAbstract: The objectives in treating angina are relief of pain and prevention of disease ­progression through risk reduction. Mechanisms, indications, clinical forms, doses, and side effects of the traditional antianginal agents – nitrates, ß-blockers, and calcium channel ­blockers – are reviewed. A number of patients have contraindications or remain unrelieved from anginal discomfort with these drugs. Among newer alternatives, ranolazine, recently approved in the United States, indirectly prevents the intracellular calcium overload involved in cardiac ischemia and is a welcome addition to available treatments. None, however, are disease-modifying agents. Two options for refractory angina, enhanced external counterpulsation and spinal cord stimulation (SCS, are presented in detail. They are both well-studied and are effective means of treating at least some patients with this perplexing form of angina. Traditional modifiable risk factors for coronary artery disease (CAD – smoking, hypertension, dyslipidemia, ­diabetes, and obesity – account for most of the population-attributable risk. Individual therapy of high-risk patients differs from population-wide efforts to prevent risk factors from appearing or reducing their severity, in order to lower the national burden of disease. Current American College of Cardiology/American Heart Association guidelines to lower risk in patients with chronic angina are reviewed. The Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation (COURAGE trial showed that in patients with stable angina, optimal medical therapy alone and percutaneous coronary intervention (PCI with medical therapy were equal in preventing myocardial infarction and death. The integration of COURAGE results into current practice is discussed. For patients who are unstable, with very high risk, with left main coronary artery lesions, in

    Full Text Available Unstable angina is an acute coronary syndrome without elevation of the ST segment. It is clinically important because of its threatening and crippling nature, due to the possibility that it could precede acute myocardial infarction. That is why it is determined that the patient suffering from this condition must be hospitalized in the Intensive Care Unit. There are various therapeutic strategies and several forms to approach the treatment of each patient, but in many cases it is necessary a percutaneous coronary intervention and this procedure is not carried out in this hospital. That is why it is necessary to establish a guideline for the treatment of this condition with the aim of optimizing the medications and making an adequate selection of the patients who require being transferred to a hospital with interventional cardiology services. A proposal for treatment protocol is presented in this work. It can function as a guideline for those who on daily basis treat patient with this condition at the Roberto Rodriguez Fernandez University Hospital in Morón city.

    We aimed to describe the imaging findings of multidetector CT coronary angiography (MDCTA) in cases of vasospastic angina (VA) and to determine the accuracy of MDCTA in the identification of VA as compared with invasive coronary angiography with an ergonovine provocation test (CAG with an EG test). Fifty-three patients with clinically suspected VA were enrolled in this study. Two radiologists analyzed the stenosis degree, presence or absence of plaque, plaque composition, and a remodeling index of the related-segment in CAG with an EG test, which were used as a gold standard. We evaluated the diagnostic performances of MDCTA by comparing the MDCTA findings with those of CAG with an EG test. Among the 25 patients with positive CAG with an EG test, all 12 patients with significant stenosis showed no definite plaque with the negative arterial remodeling. Of the six patients with insignificant stenosis, three (50%) had non-calcified plaque (NCP), two (33%) had mixed plaque, and one (17%) had calcified plaque. When the criteria for significant stenosis with negative remodeling but no definite evidence of plaque as a characteristic finding of MDCTA were used, results showed sensitivities, specificities, positive predictive values (PPV), and negative predictive values (NPV) of 48%, 100%, 100%, and 68%, respectively. Significant stenosis with negative remodeling, but no definite evidence of plaque, is the characteristic finding on MDCTA of VA. Cardiac MDCTA shows good diagnostic performance with high specificity and PPV as compared with CAG with an EG test.

    In 145 patients with unstable angina (UA) there was analized an efficiency of a drug therapy at different types of heliogeophysical activity (HA) during the 23th solar cycle. 83 patients were examined at the period of a lower HA (Kp-index 16,19±0,18), and 62 patients - at the period of a higher HA (Kp-index 17,25±0,21, p<0,05). Baseline severity of patients' condition with UA at the moment of hospitalization at the studied periods did not differ, but the effectiveness of the therapy depended on the period of HA. At the period of a higher HA antianginal effect was stronger than at the lower period of HA (2,27±0,16 points and 1,75±0,12 points, p<0,05), and the need in nitroglycerin on the background of a drug therapy disappeared for 5-7 days quicker than at the period of a lower HA. Maximal hypotensive effect at a higher HA was achieved quicker - on the 3rd day of the treatment, and at a lower HA - only up to hospital discharge (p<0,05). Blood viscosity did not normalize in both of the studied periods, but in small vessels there was noted a decrease of a BV (p<0,05). So, at a higher HA the effectiveness of a drug therapy in patients with UA is higher than at the period of a lower HA.

    The incidence of ischemic heart disease is higher in patients with HIV/AIDS. However, the frequency of angina pectoris in these patients is still not known. Literature about this subject is still scarce. To evaluate the prevalence of angina pectoris and risk factors for coronary disease and to examine the association between traditional risk factors and HIV-related risk factors and angina pectoris. An epidemiological cross-sectional study, analyzed as case-control study, involving 584 patients with HIV/AIDS. Angina pectoris was identified by Rose questionnaire, classified as definite or possible. Information regarding risk factors was obtained through a questionnaire, biochemical laboratory tests, medical records and anthropometric measures taken during consultations at AIDS treatment clinics in Pernambuco, Brazil, from June 2007 to February 2008. To adjust the effect of each factor in relation to others, multiple logistic regression was used. There was a preponderance of men (63.2%); mean ages were 39.8 years for men, 36.8 years for women. The prevalence of definite and possible angina were 11% and 9.4%, respectively, totaling 20.4%, with independent associations between angina and smoking (OR = 2.88; 95% CI: 1.69-4.90), obesity (OR = 1.62; 95% CI: 0.97-2.70), family history of heart attack (OR = 1.70; 95% CI: 1.00-2.88), low schooling (OR = 2.11; 95% CI: 1.24-3.59), and low monthly income (OR = 2.93; 95% CI: 1.18-7.22), even after adjustment for age. This study suggests that angina pectoris is underdiagnosed, even in patients with medical monitoring, revealing lost opportunities in identification and prevention of cardiovascular morbidity.

    Since the arrival of the universal definition of myocardial infarction more sensitive troponin assays have been developed. How these occurrences have influenced the proportions and clinical features of the components of acute coronary syndrome have not been studied prospectively in unselected hospital patients. During 2010 we evaluated all patients in whom cardiac troponin I had been measured at a single university hospital. The diagnosis of acute myocardial infarction (ST-elevation myocardial infarction [STEMI] or non-ST-elevation myocardial infarction [NSTEMI]) was established in cases of a rise and/or fall of cardiac troponin I together with cardiac ischemic features. Patients with unstable chest discomfort and cardiac troponin I values below the decision limit of myocardial infarction were diagnosed as having unstable angina pectoris. The definition of acute coronary syndrome included unstable angina pectoris, NSTEMI, and STEMI. Mortality data were obtained from the Danish Civil Personal Registration System. Of 3762 consecutive patients, 516 had acute coronary syndrome. Unstable angina pectoris was present in 7%, NSTEMI in 67%, and STEMI in 26%. The NSTEMI patients were older, more frequently women, and had more comorbidities than patients with unstable angina pectoris and STEMI. At median follow-up of 3.2 years 195 patients had died: 14% of unstable angina pectoris, 45% of NSTEMI, and 25% of STEMI patients. Age-adjusted log-rank statistics revealed differences in mortality: NSTEMI vs unstable angina pectoris (P = .0091) and NSTEMI vs STEMI (P = .0045). The application of the universal definition together with the use of a contemporary troponin assay seems to have reduced the proportion of patients with unstable angina pectoris to the benefit of patients with NSTEMI. Despite this, NSTEMI patients have a sustained higher mortality than patients with STEMI. Copyright © 2015 Elsevier Inc. All rights reserved.

    To determine whether unstable angina is co-related to seropositivity to chronic Helicobacter pylori (HP) infection. It is a case control, descriptive study conducted at CCU in Razi Hospital in Ahwaz a city southwest Iran, from 2004 to 2005. We measured serum HP- lgG levels of participants in CCU in a hospital. Blood samples were drawn during study period from 96 patients (mean age 56 years) with Unstable Angina (UA) according to American Heart Association criteria and from 96 participants free of cardiovascular disease (mean age 58 years) and stored at 20 degree C. Serology results were studied in relation to UA. Using chi squared test, odds ratios (OR) and 95% confidence intervals (CI) were calculated, adjusting for age, gender, and established risk factors. Seventy nine (82.3%) of patients with unstable angina and 55(61.1%) in the control group presented a positive anti HP-lgG. Odds ratio was 3 with 95% CI: 1.9 to 4.3. There was significant relation between HP-lgG positivity and unstable angina (P 0.05). Our study revealed relationship between seropositivity of HP-lgG and unstable angina. (author)

    Unstable angina represents a heterogeneous spectrum of clinical entities between chronic stable angina and acute myocardial infraction. Acute ischemic syndromes (including unstable angina) result from abrupt reduction in coronary flow, frequently after atherosclerotic plaque disruption and with or without associated thrombosis or vasospasm. Nuclear cardiology studies and in particular, myocardial perfusion imaging are powerful noninvasive tools for detecting and assessing the severity of acute ischemic syndromes, including unstable angina pec tories. The information derived from a nuclear cardiology study can answer unresolved clinical question and aid in subsequent patient management, specifically jeopardized myocardium detected during spontaneously occurring acute chest pain or controlled stress testing are important determinant of: 1) The need for admission to an intensive care monitoring unit 2) The need for and urgency of coronary angiography 3) The appropriate use of percutaneous or surgical coronary revascularization procedures. Extensive information suggests the stress nuclear perfusion imaging is the best validated technique for predischarge risk stratification with unstable angina patients who have been medically stabilized. Early information suggests avoidance of unecessary coronary angiography or revascularization is the cost effective strategy

    Cigarette smoking is not only one of the most important risk factors for coronary artery disease, but also anginal attacks often occur during smoking. Coronary vasoconstriction is considered to be one of the mechanisms which cause anginal episodes. Thirty patients with angina pectoris, 27 men and 3 women, were investigated. Group I comprised 22 patients with rest angina and group II consisted of 8 patients with effort angina. Five minutes after smoking one cigarette, a first study of 20l Tl myocardial SPECT was performed. Consequently, after sublingual administration of isosorbide denitrate, a second SPECT was done. Most cases improved and it was recognized as positive when changes of localized perfusion defects were observed between both SPECTs. In the group I, 19 out of 22 patients (86%) were positive, but in the group II, 2 out of 8 (25%) were positive. The differences were statistically significant (p<0.05). By the examination of coronarty angiography in 20 patients, the result of myocardial scintigraphy using cigarette smoking and isosorbide dinitrate seemed inversely proportional to the severity of narrowing of the coronary artery. In addition, background factors including risk factors were also compared for both groups. Because the result of this myocardial scintigraphy was positive in the rest angina group and in the group with minimal coronary arteriogrpahic abnormalities, it seggests that myocardial scintigraphy using cigarette smoking and isosorbide dinitrate is useful as a non-invasive auxiliary diagnostic method to detect coronary spasm or coronary vasoconstriction-prone angina pectoris including silent myocardial ischemia.

    The treatment of angina pectoris as a symptom of coronary artery disease usually is focused on restoring the balance between oxygen demand and supply of the myocardium by administration of drugs interfering in heart rate, cardiac pre- and afterload, and coronary vascular tone. For nonresponders to drug therapy or for those with jeopardized myocardium, revascularization procedures such as coronary bypass surgery and percutaneous transluminal coronary angioplasty are at hand. However, the atherosclerotic process is not stopped by these therapies and, at longer terms, angina may recur. It is not always possible to revascularize all the patients who do not positively react to medical treatment. Those with angina, not responding to adequate medication and who are not suitable anymore for revascularization, are considered to suffer from refractory angina pectoris. This group of patients has a poor quality of life, for their exercise tolerance is severely afflicted. For these patients, neurostimulation has been described repeatedly as an effective and safe therapy. The mechanism of action of neurostimulation is not completely known, but recent studies suggest an anti-ischemic effect, exerted through changes in myocardial blood flow. As soon as its safety is sufficiently established, it may become a useful alternative in the treatment of refractory angina pectoris.

    Myocardial uptake of the glucose analog F-18-2-fluoro-2-deoxy-D-glucose (FDG) was assessed by positron emission tomography in 6 normal volunteers, 7 patients with chronic stable angina and 22 patients with unstable angina at rest in fasting conditions. Regional myocardial perfusion was assessed by rubidium-82. The study was repeated a few days later after intravenous infusion of isosorbide dinitrate. FDG uptake was similar in control subjects and patients with stable angina (0.023 +/- 0.032 vs 0.012 +/- 0.008 mol/ml/min, p less than 0.42) but was about 4-fold higher on the average in patients with unstable angina (0.084 +/- 0.047, p less than 0.01). The severity of coronary obstructions in stable and unstable angina patients was similar. The increased uptake involved the whole heart, including areas not distal to critically stenosed vessels; it was not associated with reduced myocardial perfusion and was not related to a recent episode of transient ischemia as assessed by symptoms and by Holter monitoring. After continuous infusion of nitrates, FDG uptake was consistently and significantly reduced toward normal levels both in areas perfused by critically stenosed coronary arteries and by noncritically stenosed vessels

    Patients with a history of typical angina but negative exercise electrocardiography represent a subgroup with an intermediate likelihood of having coronary artery disease and future cardiac events. A retrospective study of the prognostic utility of stress-redistribution thallium-201 scintigraphy was performed in 190 such patients. A second group of 203 patients with typical angina and a positive exercise electrocardiogram were analyzed for comparative scintigraphic purposes. The cardiac event rate for the 144 negative exercise electrocardiogram patients with normal thallium results was 5 vs 15% in the 46 patients with abnormal thallium results (p = 0.01). These patients were further stratified into high (14 to 18%), intermediate (9%) and low (less than 2%) risk groups for future cardiac events based on combining the thallium results with the percentage of maximal predicted heart rate achieved. A multivariate analysis revealed that an abnormal thallium result was the only significant correlate of future cardiac events. Mechanisms responsible for the discordant finding of a negative exercise electrocardiogram in patients with typical angina include (1) false-positive angina symptomatology in low prevalence coronary artery disease groups in whom the thallium test is negative, and (2) electrocardiographically silent ischemia in patients in whom the thallium test is positive. These findings reveal that thallium stress-redistribution scintigraphy can be used to stratify 1-year prognosis in this subgroup of patients with typical angina and negative exercise electrocardiograms

    This meta-analysis aimed to evaluate the efficacy of trimetazidine in combination with other anti-anginal drugs versus other anti-anginal drugs in the treatment of stable angina pectoris (SAP). Randomized controlled trials (RCTs) published in English and Chinese were retrieved from computerized databases: Embase, PubMed, and CNKI. Primary outcomes consist of clinical parameters (numbers of weekly angina attacks and nitroglycerin use) and ergometric parameters (time to 1mm ST-segment depression, and total work (in Mets) and exercise duration (in seconds) at peak exercise) in stable angina pectoris treated by trimetazidine or not. The quality of studies was evaluated using Jadad score. Data analysis of 13 studies was performed using Stata 12.0 software. Results showed that treatment of trimetazidine and other anti-anginal drugs was associated with a smaller weekly mean number of angina attacks (WMD=-0.95, 95%CI: -1.30 to -0.61, Z=5.39, Pangina pectoris. Sensitivity analysis was performed. Sub-group analysis showed that treatment duration was not a significant moderator and patients treated within 8 weeks and above 12 weeks had no difference in the outcomes addressed in this meta-analysis. No publish bias was detected. This meta-analysis confirms the efficacy of trimetazidine in the treatment of stable angina pectoris, in comparison with conventional antianginal agents, regardless of treatment duration.

    Perfusion defects and 201 Tl redistribution on scintigraphic images were compared with clinical findings in 140 patients with myocardial infarction (consisting of 84 with single vessel disease and 56 with double vessel disease), 28 patients with one vessel disease not accompanied by infarction, and 18 healthy persons who underwent left coronary arteriography and 201 Tl stress myocardial scintigraphy. In 30 patients with single vessel disease accompanied by postinfarction angina pectoris, perfusion defects was smaller and Tl redistribution was larger than those in 54 patients with single vessel desease not accompanied by it. The 30 patients with postinfarction angina pectoris had a slight abnormality of left ventricular contraction and marked stenosis of 90% or more of the vessels. These findings were similar to those in the 28 angina patients who had one vessel disease but not accompanied by infarction. In 56 cases of double vessel disease, Tl redistribution was significantly larger in the group with angina than in the group without it. These results suggested that ischemia in an infarct area plays an important role as a mechanism for postinfarction angina pectoris. (Namekawa, K.)

    Alongside the remarkable advances in medical and invasive therapies for the treatment of ischemic heart disease, an increasing number of patients with advanced coronary artery disease unsuitable for revascularization continue to suffer from angina pectoris despite optimal medical therapy. Patients with chronic angina have poor quality of life and increased levels of anxiety and depression. A considerable number of innovative therapeutic modalities for the treatment of chronic angina have been investigated over the years; however, none of these therapeutic options has become a standard of care, and none are widely utilized. Current treatment options for refractory angina focus on medical therapy and secondary risk factor modification. Interventions to create increased pressure in the coronary sinus may alleviate myocardial ischemia by forcing redistribution of coronary blood flow from the less ischemic subepicardium to the more ischemic subendocardium, thus relieving symptoms of ischemia. Percutaneous, transvenous implantation of a balloon expandable, hourglass-shaped, stainless steel mesh in the coronary sinus to create a fixed focal narrowing and to increase backwards pressure, may serve as a new device-based therapy destined for the treatment of refractory angina pectoris.

    Unstable Angina (UA) is widely accepted as a critical phase of coronary heart disease with patients exhibiting widely varying risks. Early risk assessment of UA is at the center of the management program, which allows physicians to categorize patients according to the clinical characteristics and stratification of risk and different prognosis. Although many prognostic models have been widely used for UA risk assessment in clinical practice, a number of studies have highlighted possible shortcomings. One serious drawback is that existing models lack the ability to deal with the intrinsic uncertainty about the variables utilized. In order to help physicians refine knowledge for the stratification of UA risk with respect to vagueness in information, this paper develops an intelligent system combining genetic algorithm and fuzzy association rule mining. In detail, it models the input information's vagueness through fuzzy sets, and then applies a genetic fuzzy system on the acquired fuzzy sets to extract the fuzzy rule set for the problem of UA risk assessment. The proposed system is evaluated using a real data-set collected from the cardiology department of a Chinese hospital, which consists of 54 patient cases. 9 numerical patient features and 17 categorical patient features that appear in the data-set are selected in the experiments. The proposed system made the same decisions as the physician in 46 (out of a total of 54) tested cases (85.2%). By comparing the results that are obtained through the proposed system with those resulting from the physician's decision, it has been found that the developed model is highly reflective of reality. The proposed system could be used for educational purposes, and with further improvements, could assist and guide young physicians in their daily work.

    La criptococosis cutánea es una micosis propia de pacientes inmunodeprimidos, sobre todo aquellos con infección por el virusde la inmunodeficiencia humana (VIH). Sin embargo, existen casos infrecuentes de criptococosis cutánea en pacientes inmunocompetentes, que suelen simular otras dermatosis, lo que retrasa su diagnóstico y tratamiento. Presentamos el caso de un varón pluripatológico de 79 años, con úlceras dolorosas en dorso de mano derecha que no respondían a tratamientos tópicos. A través del estudio histopatológico y micológico se alcanzó el diagnóstico de criptococosis cutánea primaria, lográndose la remisión de las lesiones tras 6 meses de tratamiento con fluconazol.

    A growing number of patients with chronic artery disease suffer from angina, despite the optimal medical management (ie, β-blockers, calcium channel blockers, and long-acting nitrates) and revascularization. Currently, enhanced external counterpulsation (EECP) therapy has been verified as a noninvasive, safe therapy for refractory angina. The study was designed to evaluate the efficacy of EECP in patients with chronic refractory angina according to Canadian Cardiovascular Society (CCS) angina class.We identified systematic literature through MEDLINE, EMBASE, the Cochrane Clinical Trials Register Database, and the ClinicalTrials. gov Website from 1990 to 2015. Studies were considered eligible if they were prospective and reported data on CCS class before and after EECP treatment. Meta-analysis was performed to assess the efficacy of EECP therapy by at least 1 CCS angina class improvement, and proportion along with the 95% confidence interval (CI) was calculated. Statistical heterogeneity was calculated by I statistic and the Q statistic. Sensitivity analysis was addressed to test the influence of trials on the overall pooled results. Subgroup analysis was applied to explore potential reasons for heterogeneity.Eighteen studies were enrolled in our meta-analysis. Pooled analysis showed 85% of patients underwent EECP had a reduction by at least one CCS class (95%CI 0.81-0.88, I = 58.5%, P CCS class was about 84% after EECP (95%CI 0.81-0.88, I = 32.7%, P = 0.1668). After 3 large studies were excluded, the pooled proportion was 82% (95%CI 0.79-0.86, I = 18%, P = 0.2528). Funnel plot indicated that some asymmetry while the Begg and Egger bias statistic showed no publication bias (P = 0.1495 and 0.2859, respectively).Our study confirmed that EECP provided an effective treatment for patients who were unresponsive to medical management and/or invasive therapy. However, the long-term benefits of EECP therapy needed further studies to evaluate in the management of chronic

    Full Text Available El beneficio del tratamiento con aspirina en la reducción del riesgo de infarto de miocardio, accidente vascular cerebral y muerte de origen vascular, está bien documentado en personas con enfermedad cardiovascular previa, incluido el subgrupo portador de una diabetes mellitus. Sin embargo el papel de la aspirina en prevención primaria es menos claro y objeto de discusión: los resultados de los ensayos clínicos disponibles no son consistentes, aunque los meta-análisis son favorables en algunos aspectos. Parece existir una disparidad entre el tipo de beneficio (cuando se observa y el sexo. Y en particular los resultados son contradictorios en personas diabéticas, las cuales representan un pequeño porcentaje de la muestra de población incluida en los estudios. A pesar de esto, la American Diabetes Association desde 1997, y otras sociedades científicas (incluidas varias españolas desde tiempos más recientes, recomiendan el uso de aspirina a dosis bajas en prevención primaria en todo paciente diabético mayor de 40 años, tipo 1 o tipo 2; y en todos los menores de 40 y mayores de 21 años que presenten otro factor de riesgo cardiovascular, además de la diabetes (antecedentes familiares de enfermedad vascular, hipertensión arterial, tabaquismo, dislipidemia o albuminuria. En este trabajo se revisan los resultados de los ensayos clínicos randomizados y controlados sobre la prevención cardiovascular primaria con aspirina, en los que se podrían apoyar las directrices oficiales de la American Diabetes Association, y se llega a la conclusión de que no existen actualmente pruebas científicas suficientes para sostenerlas.

Entre marzo y abril de 2006 se realizaron mediciones de producción y crecimiento foliar en Puerto Warreo (bahía Portete y Cabo de la Vela. Se encontró que la profundidad afectó el comportamiento de las praderas (p < 0,05, con un mayor desarrollo en las praderas someras en la Alta Guajira. Este desarrollo se reflejó en la densidad foliar, densidad de vástagos, biomasa foliar, biomasa total, ancho, longitud, área e índice de área foliar, mientras que en las demás praderas, más profundas, estas variables tienen poca dimensión y el peso de epítos es alto. Los factores ambientales que mejor explican este comportamiento además de la profundidad, son intensidad de luz, sedimentos, ubicación geográfica y surgencia: las praderas con protección de bahía o ensenada, con mayor influencia de la surgencia, con alto contenido de materia orgánica y con mayor proporción de sedimentos finos son más exuberantes. La producción primaria y el crecimiento foliar se fueron medio-altos (2,40 gps m-2 día-1, y 1,24 mm día-1 comparando con otros estudios realizados en el Caribe.

    Non-communicable diseases (NCDs) are becoming a major source of the national disease burden in Myanmar with potentially serious economic implications. Using data on 5484 households from the World Health Survey (WHS), this study assessed the household-level economic burden of two chronic conditions, angina and asthma, in Myanmar. Propensity score matching (PSM) and coarsened exact matching (CEM) methods were used to compare household out-of-pocket (OOP) spending, catastrophic and impoverishment effects, reliance on borrowing or asset sales to finance OOP healthcare payments and employment among households reporting a member with angina (asthma) to matched households, with and without adjusting for comorbidities. Sensitivity analyses were carried out to assess the impacts of alternative assumptions on common support and potential violations of the assumption of independence of households being angina (asthma) affected and household economic outcomes, conditional on the variables used for matching (conditional independence). Households with angina (asthma) reported greater OOP spending (angina: range I$1.94-I$4.31; asthma: range I$1.53-I$2.01) (I$1 = 125.09 Myanmar Kyats; I$=International Dollar) almost half of which was spending on medicines; higher rates of catastrophic spending based on a 20% threshold ratio of OOP to total household spending (angina: range 6-7%; asthma: range 3-5%); greater reliance on borrowing and sale of assets to finance healthcare (angina: range 12-14%; asthma: range 40-49%); increased medical impoverishment and lower employment rates than matched controls. There were no statistically differences in OOP expenses for inpatient care between angina-affected (asthma-affected) households and matched controls. Our results were generally robust to multiple methods of matching. However, conclusions for medical impoverishment impacts were not robust to potential violations of the conditional independence assumption. Myanmar is expanding public

    Patients with symptomatic small vessel coronary artery disease may be inadequate candidates for revascularization procedures. They may suffer from refractory angina, which does not respond to maximal anti-anginal drug therapy. In addition to patients with end stage coronary artery disease and syndrome X, this newly defined group of subjects with an isolated stenosis of a small coronary artery may benefit from electrical neurostimulation. We describe two patients with intractable angina caused by a significant narrowing of a diagonal branch. This treatment modality should be considered as an alternative method for unsatisfactory revascularization procedures.

    Full Text Available Introducción: En España, el grado y las características de la utilización de los servicios sanitarios de atención primaria está siendo objeto de análisis desde, por lo menos, los años ochenta. Uno de los motivos principales es averiguar hasta qué punto dicha utilización se corresponde con unas necesidades de atención sanitaria. De hecho, se ha establecido como prioridad generalmente aceptada un servicio de salud adecuado para los pacientes que más lo necesitan. Factores condicionantes de la utilización: La evidencia muestra que las características del individuo, sobre todo su estado de salud, son las que se relacionan principalmente con la utilización de servicios de atención primaria. Otras características personales, como el sexo y la edad, podrían actuar como moduladores de la necesidad de atención. Algunas variables familiares y/o culturales, así como las variables relacionadas con el profesional sanitario y otras institucionales, podrían explicar también parte de la variabilidad observada en la utilización de los servicios de atención primaria. Respecto a las variables socioeconómicas, como la renta, se produce una situación paradójica. De forma añadida, existe una evidencia empírica que demuestra que la renta constituye el principal determinante, tanto de la utilización como del gasto sanitario. Cuando se analizan los datos individuales, sin embargo, dicha variable no está relacionada con la utilización de servicios de atención primaria. Inconsistencias metodológicas: La situación es controvertida, con implicaciones no simplemente metodológicas sino, sobre todo, respecto al análisis de la eficiencia en la utilización de los servicios sanitarios de atención primaria. El problema es que, revisando la bibliografía, se pueden apreciar ciertas inconsistencias metodológicas que podrían explicar, al menos en parte, la disparidad de los resultados obtenidos. Entre otras, cabe citar las siguientes

    La palabra Inter-és proviene etimológicamente de las palabras latinas inter y esse; y significa “lo que está-entre dos o más personas, o sea lo que las une pero también las separa”. Los prefijos inter- y entre-, en la mayor parte de los casos, describen estados o acciones ambiguas de los términos que preceden.

    Full Text Available Objetivos: Desde 2007 la normativa relativa a la gestión por la Seguridad Social de las Enfermedades Profesionales y al sistema de información para su vigilancia epidemiológica, asigna a los médicos en Atención Primaria un papel como comunicadores a partir de su "sospecha diagnóstica". Este trabajo pretende mostrar algunas de sus necesidades expresadas en relación al conocimiento específico y sus actitudes y sensibilización en su práctica cotidiana respecto al origen laboral de estas patologías. Métodos: Para ello, hemos analizado los textos generados en la interacción entre los alumnos y tutores participantes en 2 ediciones de un curso online ("Enfermedades Profesionales para Médicos de Atención Primaria" realizado sobre el campus electrónico de la Escuela Nacional de Medicina del Trabajo del Instituto de Salud Carlos III, promovido y financiado por el Ministerio de Sanidad, entre otros. Resultados: Los participantes expresan su inquietud en relación con: i su falta de conocimientos específicos, ii la carencia de utilidades o instrumentos habilitados en las historias clínicas informatizadas para orientarles en el diagnóstico de procesos "presumiblemente" laborales, y iii los problemas de comunicación entre los actores del sistema. Conclusiones: Destacamos su interés por saber cómo establecer el origen laboral de algunos procesos en un sentido amplio, más allá de la determinación de Enfermedad Profesional, y cómo apuntan soluciones que contemplarían: aumentar sus conocimientos, facilitarles el asesoramiento por expertos, hacer más visible lo laboral en la historia clínica de atención primaria y habilitar canales de comunicación eficaces con el resto de implicados en la gestión de las enfermedades profesionales.

Además, indagamos sobre la formación profesional docente en sexualidad y género, para lo cual nos basamos en testimonios de cuatro entrevistas efectuadas al profesorado de primaria de los Estados del sureste mexicano de Quintana Roo y Yucatán: dos de quinto grado y dos de sexto. Los resultados muestran que los contenidos de los libros de texto reducen la sexualidad a la reproducción, y no incorporan el erotismo, el cual es considerado relevante en el enfoque de educación integral de la sexualidad. Asimismo, transmiten ideas heteronormativas sobre las vinculaciones afectivas, y no incorporan la perspectiva de género a cabalidad, ya que fracasan en denunciar la desigualdad entre hombres y mujeres. La formación de docentes es deficiente y hace evidente la operación del currículo oculto, pues se transmiten estereotipos y prejuicios de género y sexualidad.

Los resultados demuestran que los docentes necesitan formación en esta área, que la enseñanza en alfabetización mediática es adecuada en términos de contenido pero inadecuada como actividad. Los estudiantes muestran cambios significativos en sus propias percepciones sobre los medios tras recibir clases de alfabetización mediática. Para evaluar el nivel y la actitud de los estudiantes se aplicaron una escala de alfabetización mediática y una escala de actitud. La información se obtuvo a través de un formulario de información privado desarrollado por los investigadores. En las conclusiones se halló una relación significativa, positiva y de bajo nivel entre los grados de actitud hacia los contenidos de la alfabetización mediática. La principal conclusión obtenida es que no existe una diferencia significativa entre los estudiantes que asisten a clases de alfabetización mediática en segundo grado de educación primaria y sus actitudes en el aula y su nivel de alfabetización. Asimismo, tampoco se aprecia una diferencia significativa entre el nivel educativo de los padres y sus actitudes. Sin embargo, sí se aprecian diferencias notables cuando existe hábito de lectura diaria de la prensa y la radio.

Existen múltiples variables que tienen correlación con este elemento de entre los cuales están las competencias sociales (Berra y Dueñas, 2009. En el presente trabajo se describen la aplicación y el diseño de dos estrategias elaboradas bajo la técnica del Entrenamiento en Habilidades Sociales, las cuales tienen como objetivo impactar en la convivencia escolar en un grupo de 12 niños de cuarto año de primaria. Se procedió primeramente con observaciones realizadas dentro del aula, después se elaboraron las actividades y se implementaron a los niños seleccionados, evaluando su eicacia con preguntas relexivas y ensayos conductuales y mediante una entrevista semiestructurada con la maestra titular. En los resultados obtenidos se observó que durante las sesiones los niños no tenían problemas para distinguir entre conductas socialmente positivas y negativas pero hubo diicultad a la hora de los ensayos de conducta. La entrevista con la maestra titular evidenció un cambio en la convivencia escolar dentro del salón de clases, sin embargo las habilidades adquiridas sólo fueron implementadas en situaciones especíicas por lo que se vuelve indispensable la integración de elementos o la modiicación de las actividades para la generalización y formación de competencias sociales.

    Full Text Available OBJECTIVES: To compare health-related quality of life (HRQoL between patients with stable angina and the general population in China and to examine factors associated with HRQoL among patients with stable angina. METHODS: A cross-sectional HRQoL survey of stable angina patients recruited from 4 hospitals (n = 411 and the general population recruited from 3 Physical Examination Centers (n = 549 was conducted from July to December, 2011 in two large cities, Tianjin and Chengdu. HRQoL was assessed using the EQ-5D, EQ-VAS, and SF-6D instruments. The health status specific to patients with stable angina was assessed using the Seattle Angina Questionnaire (SAQ. Information on socio-demographic, clinical, and lifestyle factors were also collected. Nested regressions were performed to explore how these factors were associated with HRQoL in patients with stable angina. RESULTS: Compared with the general population (44.2 ± 10 years, 49.9% females, stable angina patients (68.1 ± 12 years, 50.4% females had significantly lower HRQoL scores in EQ-5D utility index (0.75 ± 0.19 vs. 0.90 ± 0.20, p<0.05, SF-6D utility index (0.68 ± 0.12 vs. 0.85 ± 0.11, p<0.05, and EQ-VAS (71.2 ± 12.3 vs. 83.9 ± 10.9, p<0.05. The differences remained (-0.05 for EQ-5D, -9.27 for EQ-VAS and -0.13 for SF-6D after controlling for socio-economic characteristics. SAQ scores showed that stable angina patients experienced impaired disease-specific health status, especially in angina stability (40.5 ± 34.6. Nested regressions indicated stable angina-specific health status explained most of the variation in HRQoL, among which disease perception, physical limitation, and angina stability were the strongest predictors. More physical exercise and better sleep were positively related with HRQoL. CONCLUSIONS: Compared to the general population, stable angina patients were associated with lower HRQoL and lower health utility scores, which were largely impacted by clinical symptoms

Para ello, los datos obtenidos mediante la Escala de Irritación se contrastaron con otro instrumento que evalúa estrés, el Cuestionario Breve de Burnout adaptado para profesores, esperando obtener correlaciones positivas entre ambos instrumentos. Además, se utilizaron otros dos instrumentos adicionales, la Escala de Autoeficacia General y la Escala de Autorregulación, con la hipótesis de obtener una correlación negativa con la Escala de Irritación. Los resultados obtenidos confirmaron las hipótesis planteadas en este estudio, dado que se obtuvieron correlaciones positivas y significativas entre los resultados de la Escala de Irritación y el Cuestionario Breve de Burnout. Mientras tanto, las correlaciones de la Escala de Irritación con las otras dos escalas fueron negativas y también significativas. Por tanto, los análisis estadísticos corroboran la validación de la Escala de Irritación y su utilidad para la evaluación del estrés entre el profesorado de Educación Primaria.

    Angina pectoris impairs patients' quality of life. In order to assess its impact on quality of life, a questionnaire was developed using a literature review and interviews with patients and clinicians. It consisted of a general profile (SF-36) which measured functional status, well-being, perceived health, and a specific index, the Angina Pectoris Quality of Life Questionnaire, supplemented by new items. The acceptability, internal consistency reliability and clinical validity of this 70-item questionnaire were analysed in a cross-sectional study. Of 197 coronary patients approached, 93% (n = 184) agreed to participate and 86% (n = 170) returned the mailed questionnaire. Mean age of patients was 67 years (+/- 10); 79% were male and 70% were retired. Sixty patients were asymptomatic and 110 reported anginal crises (Canadian Cardiovascular Society Classification: class I: 48; II: 37; III: 13; IV: 0; V: 12). Globally, angina pectoris was found to affect each quality of life concept measured: physical functioning, well-being, and perceived health. Quality of life profiles worsened in accordance with increasing severity of the condition, as stratified by angina pectoris class. Asymptomatic patients reported better general and specific profiles. These results support the feasibility and usefulness of evaluating quality of life using the questionnaire. The validation of the data is very encouraging and enables the questionnaire to be used in clinical trials.

    With the rising incidence as well as the medical expenditure among patients with unstable angina pectoris, the research aimed to investigate the inpatient medical expenditure through the combination of diagnosis-related groups (DRGs) among patients with unstable angina pectoris in a Grade A tertiary hospital to conduct the referential standards of medical costs for the diagnosis. Single-factor analysis and multiple linear stepwise regression method were used to investigate 3933 cases between 2014 and 2016 in Beijing Hospital (China) whose main diagnosis was defined as unstable angina pectoris to determine the main factors influencing the inpatient medical expenditure, and decision tree method was adopted to establish the model of DRGs grouping combinations. The major influential factors of inpatient medical expenditure included age, operative method, therapeutic effects as well as comorbidity and complications (CCs) of the disease, and the 3933 cases were divided into ten DRGs by four factors: age, CCs, therapeutic effects, and the type of surgery with corresponding inpatient medical expenditure standards setup. Data of nonparametric test on medical costs among different groups were all significant (P angina pectoris is conducive in standardizing the diagnosis and treatment behaviors of the hospital and reducing economic burdens among patients.

    A challenge of modern cardiovascular medicine is to find new, effective treatments for patients with refractory angina pectoris, a clinical condition characterized by severe angina despite optimal medical therapy. These patients are not candidates for surgical or percutaneous revascularization. Herein we review the most up-to-date information regarding the modern approach to the patient with refractory angina pectoris, from conventional medical management to new medications and shock wave therapy, focusing on the use of endothelial precursor cells (EPCs) in the treatment of this condition. Clinical limitations of the efficiency of conventional approaches justify the search for new therapeutic options. Regenerative medicine is considered the next step in the evolution of organ replacement therapy. It is driven largely by the same health needs as transplantation and replacement therapies, but it aims further than traditional approaches, such as cell-based therapy. Increasing knowledge of the role of circulating cells derived from bone marrow (EPCs) on cardiovascular homeostasis in physiologic and pathologic conditions has prompted the clinical use of these cells to relieve ischemia. The current state of therapeutic angiogenesis still leaves many questions unanswered. It is of paramount importance that the treatment is delivered safely. Direct intramyocardial and intracoronary administration has demonstrated acceptable safety profiles in early trials, and may represent a major advance over surgical thoracotomy. The combined efforts of bench and clinical researchers will ultimately answer the question of whether cell therapy is a suitable strategy for treatment of patients with refractory angina.

    Some patients of ischemic heart disease have low uptake in 123 I-labeled beta methyl-iodophenyl pentadecanoic acid (BMIPP) SPECT in spite of normal uptake in thallium-201 (Tl) SPECT. To investigate their clinical significance, we performed both Tl and BMIPP myocardial SPECT in 26 cases with stable angina (n=16) and unstable angina (n=10), and compared with clinical backgrounds electrocardiogram (ECG) and left ventriculography (LVG). In 11 patients of them, the uptake of BMIPP was moderately reduced. We divided 26 cases into two groups according to uptake of BMIPP (normal/reduced). The two groups had no differences in length of angina attack and duration of disease, but they had a significant difference in the abnormality of either ECG or LVG. Three to six months after PTCA, we examined LVG in 18 cases, 12 of 16 cases with the abnormality of LVG showed the improvement of wall motion. We concluded the reduced uptake of BMIPP with normal uptake of Tl was related to more severe ischemia in cases with unstable angina. (author)

    Tongxinluo capsule is a medicine consisting of traditional Chinese herbs and insects used for cardiovascular diseases in China and some other Asian countries. To date the evidence of its effect has not previously been subject to systematic review, making it difficult to derive robust conclusions about its actual benefits, and indeed, possible harms. To assess systematically the effects of tongxinluo capsule in people with unstable angina pectoris. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, Issue 4 2004, MEDLINE, EMBASE, Chinese Biomedical Database, China National Knowledge Infrastructure, Japana Centra Revuo Medicina (all 1995 to 2005). We also handsearched the relevant Chinese journals, checked with manufacturers and registers of ongoing studies. Randomised trials comparing either tongxinluo capsule only or standard treatment plus tongxinluo capsule with standard treatment or other anti-angina pectoris drugs, placebo or no intervention. Two authors identified relevant studies for the review independently and went on to abstract data, and assess trial quality. Authors of included studies were contacted to obtain further information as required. 18 short term follow-up trials involving 1413 people were included. The studies did not provide strong support of a benefit of tongxinluo for reducing the combined outcome of acute myocardial infarction, angioplasty (PTCA) coronary artery bypass graft (CABG) and sudden death or all-cause mortality (RR 0.42, 95% CI 0.07 to 2.59, P=0.35; RR 0.33, 95% CI 0.01to 7.78, P=0.49, respectively). Tongxinluo reduced the frequency of acute angina attacks (WMD -1.20, 95%CI -1.38 to -1.02, P<0.00001 and RR -2.36, 95%CI -2.53 to -2.18, P<0.00001, respectively), improved ECG (RR 1.31, 95% CI 1.08 to 1.57, P=0.005) and angina symptoms (RR 1.21, 95% CI 1.06 to 1.40; P=0.007). Tongxinluo in combination with routine angina therapy appears to reduce the risk of subsequent AMI, PTCA or CABG

    Several animal experiments on acute myocardial infarction (AMI) have shown that the cardioprotective effects of ischemic preconditioning are more significant in hypertensive subjects. However, because there are no clinical data on the impact of hypertension on ischemic preconditioning in patients with AMI, whether clinical ischemic preconditioning of prodromal angina was beneficial in AMI patients with hypertension was investigated in the present study. 125 patients with a first anterior AMI who had undergone successful reperfusion therapy were divided into 2 groups, with or without hypertension, and into 2 further subgroups based on the presence or absence of prodromal angina. Dual-isotope (thallium-201(TL)/Tc-99m pyrophosphate) single-photon emission computed tomography (SPECT) was performed within 1 week of reperfusion therapy. Left ventricular (LV) function and LV mass index (LVMI) were measured by left ventriculography and echocardiography, respectively. In patients without hypertension, prodromal angina resulted in significantly less myocardial damage on TL-SPECT, better LV ejection fraction and a greater myocardial blush grade compared to patients without prodromal angina. However, these cardioprotective effects of prodromal angina were significantly diminished in hypertensive patients. Importantly, the myocardial salvage effects of prodromal angina showed a significant negative correlation with LVMI, which was significantly greater in hypertensive patients. The cardioprotective effects of prodromal angina were attenuated in patients with hypertension. Hypertensive LV hypertrophy may crucially limit the effects of ischemic preconditioning in AMI.

    Vascular endothelial growth factor (VEGF) induces mobilization of endothelial progenitor cells (EPCs) with the capacity for proliferation and differentiation into mature endothelial cells, thus contributing to the angiogenic process. We sought to assess the behavior of EPCs in patients with ischemic heart disease and refractory angina who received an intramyocardial injections of 2000 µg of VEGF 165 as the sole therapy. The study was a subanalysis of a clinical trial. Patients with advanced ischemic heart disease and refractory angina were assessed for eligibility. Inclusion criteria were as follows: signs and symptoms of angina and/or heart failure despite maximum medical treatment and a myocardial ischemic area of at least 5% as assessed by single-photon emission computed tomography (SPECT). Exclusion criteria were as follows: age > 65 years, left ventricular ejection fraction < 25%, and a diagnosis of cancer. Patients whose EPC levels were assessed were included. The intervention was 2000 µg of VEGF 165 plasmid injected into the ischemic myocardium. The frequency of CD34+/KDR+ cells was analyzed by flow cytometry before and 3, 9, and 27 days after the intervention. A total of 9 patients were included, 8 males, mean age 59.4 years, mean left ventricular ejection fraction of 59.3% and predominant class III angina. The number of EPCs on day 3 was significantly higher than that at baseline (p = 0.03); however, that on days 9 th and 27 th was comparable to that at baseline. We identified a transient mobilization of EPCs, which peaked on the 3th day after VEGF 165 gene therapy in patients with refractory angina and returned to near baseline levels on 9 th and 27 th days

    To assess the effect (harms and benefits) of nitrates for stable angina. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. Randomized controlled trials with both parallel and crossover design were included. The following outcome measures were evaluated: number of angina attacks weekly and nitroglycerin consumption, quality of life, total exercise duration, time to onset of angina and time to 1 mm ST depression. Fifty-one trials with 3595 patients meeting inclusion criteria were analyzed. Both intermittent and continuous regimens of nitrates lengthened exercise duration significantly by 31 and 53 s respectively. The number of angina attacks was significantly reduced by 2.89 episodes weekly for continuous administration and 1.5 episodes weekly for intermittent administration. With intermittent administration, increased dose provided with 21 s more length of exercise duration. With continuous administration, exercise duration was pronged more in low-dose group. Quality of life was not improved by continuous application of GTN patches and was similar between continuous and intermittent groups. In addition, 51.6% patients receiving nitrates complained with headache. Long-term administration of nitrates was beneficial for angina prophylaxis and improved exercise performance but might be ineffective for improving quality of life. With continuous regimen, low-dose nitrates were more effective than high-dose ones for improving exercise performance. By contrast, with intermittent regimen, high-dose nitrates were more effective. In addition, intermittent administration could bring zero-hour effect. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Purpose: Based on our preclinic studies with autologous unfractionated bone marrow (AUBM) via coronary sinus with transitory occlusion, a clinic study in patients with chronic stable angina was designed. The objectives were to evaluate safety, tolerance and feasibility. Methods and materials: A multicenter prospective study with inclusion and exclusion criteria defined by an Independent Clinical Committee was carried out. Fourteen patients underwent transcoronary sinus administration of freshly aspirated and filtered AUBM (60-120 ml). Safety and tolerance were evaluated. Feasibility was evaluated with Seattle Angina Questionnaire (SAQ), Canadian Cardiovascular Society (CCS) angina classification (baseline-Day 180), myocardial perfusion (baseline-Day 90) with independent core laboratory and coronary angiography (baseline and Day 30). Results: There were no changes in the safety and tolerance parameters. Preliminary clinical efficacy at Day 180 disclosed a significant improvement of 38%, evaluated by the SAQ. The CCS angina classification shows that the mean angina class was 3.0±0.55 at baseline and improved to 2.0±0.00 at Day 180 (P<.001). Semiquantitative radionuclide perfusion imaging (core lab) showed a significant improvement at Day 90 in 13/14 patients, with a mean improvement of 24% at rest (P<.01) and 33% at stress (P<.05). Coronary angiography showed more collateral vessels in 9/14 patients. Conclusions: We can conclude that AUBM via coronary sinus with transitory occlusion is tolerable and safe. Significant improvement in the myocardial perfusion at Day 90 and in the quality of life at Day 180 was observed

    The aim of this prospective study was to determine the value of quantitative exercise thallium-201 scintigraphy for predicting short-term outcome in patients after percutaneous transluminal coronary angioplasty (PTCA). Quantitative exercise thallium-201 scintigraphy was performed 2.2 +/- 1.2 weeks after successful PTCA in 68 asymptomatic patients, 64 (94%) of whom had class III or IV angina before the procedure. Clinical follow-up was obtained in all patients at a mean of 10 +/- 2 months and all were followed for at least 6 months; 45 patients (66%) remained asymptomatic during follow-up and 23 (34%) developed recurrent class III or IV angina at a mean of 2.6 +/- 1.2 months. Multivariate analysis of 22 clinical, angiographic and exercise test variables revealed that thallium-201 redistribution, any thallium scan abnormality, presence of a distal stenosis and treadmill time were the only significant predictors of recurrent angina after PTCA. Using a stepwise discriminant function model, thallium-201 redistribution was the only significant independent predictor. Despite its prognostic value relative to other variables as a predictor, thallium redistribution at 2 weeks after PTCA was only detected in 9 of the 23 patients (39%) who subsequently developed recurrent angina, although only 2 of the 45 patients (9%) who remained asymptomatic during follow-up demonstrated thallium-201 redistribution at the time of early testing. After repeat angiography was performed in 17 of the 23 patients with recurrent angina, 14 (82%) demonstrated restenosis and 3 (18%) had worse narrowing distal to or remote from the site of dilatation

    Epidural spinal cord stimulation (SCS) provides symptom relief in refractory angina pectoris, but its mechanism of action remains incompletely understood. We studied effects of short-term SCS therapy on myocardial ischaemia tolerance, myocardial perfusion reserve (MPR), and endothelium-mediated vasodilatation induced by cold pressor test (CPT) in patients with refractory angina pectoris. We prospectively recruited 18 patients with refractory angina pectoris and studied them after implantation of SCS device at baseline before starting the therapy and after 3 weeks of continuous SCS therapy. Myocardial ischaemia was evaluated by dobutamine stress echocardiography. Global and regional myocardial blood flow (MBF) were measured using positron emission tomography and (15)O-water at rest, during adenosine stress, and in response to CPT. Systemic haemodynamics were comparable before and after 3 weeks of SCS at rest, during adenosine stress and during CPT. Appearance of angina pectoris induced by dobutamine stress was delayed after SCS therapy. Global MPR increased (P = 0.02) from 1.7 ± 0.6 at baseline to 2.0 ± 0.6 after 3-week SCS therapy. This was associated with a significant reduction in global MBF at rest and increase in MBF induced by adenosine in the ischaemic regions. Global MBF response to CPT was improved after SCS (0.27 ± 0.20 vs. 0.40 ± 0.15, P = 0.03). Short-term SCS therapy improved myocardial ischaemia tolerance, absolute MPR, and endothelium-mediated vasomotor function in refractory angina pectoris, indicating that this therapy can alleviate myocardial perfusion abnormalities in advanced CAD.

    In order to determine whether there are differences in myocardial perfusion at rest among patients with various unstable and stable angina syndromes, serial thallium-201 imaging was performed at rest in 19 patients presenting with rapidly worsening exertional angina (unstable angina, group A), 12 patients with rest angina alone without exertional symptoms (unstable angina, group B), and 34 patients with chronic stable angina. No patient had an episode of angina within 4 hours of study. Nineteen of 19 (100%) patients in group A demonstrated transient defects compared to only 3 of 12 (25%) patients in group B (p less than 0.0001) and 4 of 34 (12%) stable angina patients (p less than 0.0001). The majority of zones demonstrating transient defects in group A were associated with hypokinesis of the corresponding left ventriculogram segment without associated ECG evidence of previous infarction. There were no significant differences in the frequency of persistent thallium defects, severity of angiographic coronary artery disease, or frequency of regional wall motion abnormalities of myocardial segments supplied by stenotic coronary arteries among the three groups of patients. Transient defects have been shown to reflect reduction in regional coronary blood flow to viable myocardium. Therefore, we conclude that regional resting hypoperfusion of viable myocardium is far more common in patients with exertional unstable angina symptoms than in patients with rest angina alone or chronic stable angina

The respondent was presented with the short Rose questionnaire with three questions, adapted by Lawlor in 2003 and validated in Brazil, to identify angina pectoris grade I (mild) and II (moderate/severe). The prevalence rate was calculated with a 95% confidence interval (95%CI) according to sex, age, education, and race/color. The prevalence of mild angina (grade I) was of 7.6% (95%CI 7.2 - 8.0) for the entire population, more frequently in women - 9.1% (95%CI 8.5 - 9.7) - than in men - 5.9% (95%CI 5.3 - 6.4). The frequency of moderate/severe angina (grade II) was of 4.2 (95%CI 3.9 - 4.5), also more common in women - 5.2% (95%CI 4.7 - 5.6) - than in men - 3.0% (95%CI 2.7 - 3.4). The prevalence of angina by age group increased progressively with age. The prevalence of angina of any sort was inverse to years of formal study. Despite the higher value of the presence of angina in black people, there was no significant difference by race/skin color. The high prevalence rate of angina pectoris in the population aged 18 years and above was consistent with studies in other countries, revealing the importance of coronary heart disease as a public health problem.

    Full Text Available Aprender a convivir es uno de los temas prioritarios de la educación actual. Los conflictos en educación física muestran la existencia de desequilibrios en la interacción entre iguales. Este trabajo investigó los conflictos motores en una unidad didáctica de juegos de oposición en alumnos de un centro de educación primaria. Se identificó el índice de conflictividad de esas relaciones, las conductas que originaron esos conflictos y también las reacciones. Los resultados aportaron informaciones precisas del perfil conflictivo del grupo en situaciones de juego y sirvieron para reorientar las siguientes intervenciones del profesor orientadas hacia una transformación pedagógica de los conflictos.

En este trabajo se muestran actividades prácticas que buscan explícitamente favorecer en las aulas la equidad de género: cuentos, canciones, preguntas a los niños para propiciar diálogos y conceptualizaciones surgidas de ellos, tareas familiares y reflexiones sobre la didáctica aplicada en la comunidad educativa, comunidad que incluye a maestros, padres de familia, niños y a todo el personal de la escuela. El Programa jvlv se creó en el Departamento de Educación y Comunicación de la uam-x, y hoy se aplica en más de 1000 primarias oficiales del estado de Chiapas. El programa se experimentó como programa piloto primero en diez jardines de niñas y niños en el año escolar 2001-2002, posteriormente en seis primarias oficiales en 2003-2004 y hoy se desarrolla un nuevo programa piloto en 52 primarias en los municipios de Tuxtla Gutiérrez y Suchiapa. La concepción de equidad se tiende a identificar con la de justicia, entendida como dar beneficio a los demás, al medio ambiente y a uno mismo. La equidad de género supone centrar la atención en hacer bien tanto a hombres como a mujeres, sistemáticamente.

    Full Text Available El formato hipertextual aporta una nueva dimensión a la comprensión lectora añadiendo a la propia escritura una estructura en forma de red semántica que aumenta las posibilidades de relacionar conceptos e ideas a medida que se navega por ella. Este trabajo se plantea estudiar los efectos del formato hipertextual sobre la comprensión lectora y la memoria textual en el ámbito de la educación primaria, partiendo de las actuales teorías del procesamiento de la información y los procesos de comprensión y memoria en el campo de la Psicología y la Pedagogía. Esta investigación busca analizar las diferencias entre la comprensión y el recuerdo de un texto presentado de forma lineal e hipertextual a dos grupos de alumnos de quinto curso de primaria, y determinar si estas son significativas y en qué sentido apuntan para profundizar y aportar datos más precisos sobre las herramientas educativas digitales en el contexto del programa de digitalización de las aulas de primaria de la Generalitat de Catalunya. En este sentido, el estudio parte de la hipótesis de que el formato hipertextual de la información mejora su consolidación y almacenamiento a corto y a largo plazo debido a la estructura de sus nodos (fragmentos de información en forma de red, que la asimilan a la forma de organización neuronal del cerebro humano, así como a su funcionamiento por asociación de ideas y conceptos. Dado que la información se organiza en la mente humana a través de una extensa red neuronal, la información procesada y consolidada siguiendo las mismas pautas de asociación y conectividad entre nodos, es relacionada más rápidamente con aquellos conocimientos ya consolidados en el cerebro y, por lo tanto, se asimila más rápidamente, permitiendo un almacenamiento más profundo y duradero en el tiempo.

    Full Text Available En la última década diversos estudios han demostrado que las habilidades fonológicas suprasegmentales o prosódicas (conocimiento de los rasgos prosódicos del lenguaje tales como el acento, las pausas y la entonación influyen en el desarrollo de la lectoescritura. Sin embargo, la mayoría de los estudios se han realizado en inglés y se han centrado fundamentalmente en el análisis de las habilidades suprasegmentales a nivel léxico. Este estudio analiza las relaciones entre las habilidades suprasegmentales y el desarrollo lector en 92 niños españoles de 5º de Educación Primaria. Se tomaron medidas de vocabulario, conciencia fonológica y habilidades suprasegmentales (conciencia del acento en palabras y pseudopalabras, nombres compuestos y ritmo no lingüístico así como de lectura de palabras y comprensión lectora. Los resultados muestran que las habilidades suprasegmentales predicen un porcentaje significativo de la varianza en las habilidades lectoras, una vez controlada la influencia de la conciencia fonológica y del vocabulario. Además, las diferentes habilidades prosódicas (conciencia prosódica a nivel léxico, métrico y ritmo no lingüístico presentan distintos patrones de relación con las habilidades lectoras.

    2016-01-01

    We systematically assess the current clinical evidence of Gualouxiebaibanxia (GLXBBX) decoction for the treatment of angina pectoris (AP). We included RCTs testing GLXBBX against conventional drugs and GLXBBX combined with conventional drugs versus conventional drugs. 19 RCTs involving 1730 patients were finally identified, and the methodological quality was evaluated as generally low. The results of the meta-analysis showed that GLXBBX alone had significant effect on improving angina symptoms (RR: 1.24, 95% CI 1.14 to 1.35; P angina symptoms (RR: 1.17 [1.12,1.22]; P angina symptoms in participants with AP. However, the evidence remains weak due to the poor methodological quality of the included studies. More rigorous trials are needed to confirm the results. PMID:27777598

    Race and sex disparities in in-hospital treatment and outcomes of patients with acute myocardial infarction (MI) have been described, but little is known about race and sex differences in post-MI angina and long-term risk of unplanned rehospitalization. We examined race and sex differences in post-MI angina frequency and 1-year unplanned rehospitalization to identify factors associated with unplanned rehospitalization, testing for whether race and sex modify these relationships. Using TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome) data, we examined 6-week and 1-year angina frequency and 1-year unplanned rehospitalization stratified by race and sex among MI patients treated with percutaneous coronary intervention. We used multivariable logistic regression to assess factors associated with unplanned rehospitalization and tested for interactions among angina frequency, race, and sex. A total of 11 595 MI patients survived to 1 year postdischarge; there were 66.6% white male patients, 24.3% white female patients, 5.3% black male patients, and 3.8% black female patients. Overall, 29.7% had angina at 6 weeks, and 20.6% had angina at 1 year postdischarge. Relative to white patients, black patients were more likely to have angina at 6 weeks (female: 44.2% versus 31.8%; male: 33.5% versus 27.1%; both Prace or sex (adjusted 3-way P interaction =0.41). One-fifth of MI patients treated with percutaneous coronary intervention report 1-year postdischarge angina, with black and female patients more likely to have angina and to be rehospitalized. Better treatment of post-MI angina may improve patient quality of life and quality of care and help to lower rates of rehospitalization overall and particularly among black and female patients, given their high prevalence of post-MI angina.

    Full Text Available Resumen Desde hace casi cuatro años un numeroso grupo de investigadores españoles de más de veinte universidades del país estudian los niveles de competencia mediática de la ciudadanía para promover así programas de alfabetización mediática en las escuelas y entornos no formales. La competencia mediática es un concepto que abarca nuestras habilidades y conocimientos frente a los medios de comunicación y puede ser medida a través de seis dimensiones: lenguaje, tecnología, producción y programación, recepción y audiencias, ideología y valores y finalmente la estética. Concretamente, en el estudio descriptivo que aquí se presenta, se explora el grado de dicha competencia en el caso concreto de escolares de cuarto de Educación Primaria de entre nueve y diez años, en el contexto español. Para ello fue necesario el diseño e implementación de un cuestionario online, adaptado a sus edades tanto en el contenido como en el diseño, para poder conocer si los 581 participantes que componen la muestra son competentes desde el punto de vista mediático. Los resultados muestran que nada es lo que parece. Pese a lo que se pudiera suponer, es necesario una mayor formación en medios entre el alumnado de esta etapa obligatoria y por tanto se precisan programas de alfabetización mediática en las escuelas y también en los entornos familiares.

    Full Text Available Como agente reflexivo de su propia práctica, el profesorado construye creencias pedagógicas sobre el proceso de enseñanza y aprendizaje y, en particular, sobre el rol que sus estudiantes deben asumir en el aprendizaje de un idioma. Este estudio tiene como objetivo identificar las creencias pedagógicas de treinta docentes de inglés de primaria, secundaria y terciaria, en Chile, sobre el rol estudiantil en el proceso didáctico. Un cuestionario, una entrevista semi-estructurada, un diario auto-biográfico y cinco diarios de observación no-participante fueron utilizados para revelar las creencias pedagógicas de sus informantes. Los datos arrojados por los instrumentos fueron analizados con el programa cualitativo ATLASTI, que permitió el levantamiento de tres dimensiones y diez categorías, mediante el uso de la técnica del análisis de contenido semántico. Los resultados muestran que los tres grupos de profesorado declaran que estudiantes que aprenden una lengua extranjera deben tener características personales y académicas relacionadas con la motivación, la participación, la autonomía, entre otras; sin embargo, al interior del aula asumen un rol pasivo y reactivo frente al ambiente de enseñanza altamente estructurado que genera el personal docente. En conclusión, las creencias que cada docente sostiene se alimentan de la teoría y se corroboran o cuestionan en la práctica de aula, a modo de una relación bidireccional entre teoría y práctica, y viceversa.

    Recruitable coronary collaterals may appear when spasm suddenly occludes the coronary artery. We report a patient with variant angina who had visible collateral vessels on a control coronary angiogram, despite the presence of normally appearing coronary arteries. These collaterals disappeared after intracoronary administration of nitroglycerin. These findings suggest that recruitable collateral vessels can remain patent long after spontaneous attacks of angina have resolved, and become visible when there is a pressure difference between two small coronary arteries.

    Coronary Heart Disease (CHD) occurs to a greater extent in developed than developing countries like Pakistan. Our understanding of risk factors leading to this disease in women, are largely derived from studies carried out on samples obtained from developed countries. Since prevalence of CHD in Pakistan is growing, it seems pertinent to infer risk and protective factors prevalent within the Pakistani women. This case control study investigated the role of psychological, traditional and gender specific risk and protective factors for Angina in a sample of Pakistani women aged between 35-65 years. Methods: Female patients admitted with first episode of Angina fulfilling the study inclusion/exclusion criteria were recruited within the first three days of stay in the hospital. One control per case matched on age was recruited. Translated versions of standardized tools: Life Orientation Test (LOT), The Hope Scale, Subjective Happiness Scale and Depression, Anxiety and Stress Scale (DASS) were used to measure the psychological variables. Information on medical conditions like diabetes, hypertension, family history of IHD, presence and absence of menopause and use of oral contraceptive pills was obtained from the participants. Body Mass Index for cases and controls was calculated separately with the help of height and weight recorded for the participants. Results: Multivariate logistic regression analyses revealed that depression, anxiety and stress are risk factors, were as optimism and hope are protective predictors of Angina. 64% and 85 % of variance in Angina were attributed to psychological factors. Menopause, diabetes and hypertension are significantly associated with the risk of Angina, explaining 37% and 49 % of variance in Angina. The study provides evidence for implementation of gender specific risk assessment and preventive strategies for Angina. The study gives directions for large scale prospective, epidemiological, longitudinal as well as interventional

    To assess the clinical significance of iodine-123 beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) single photon emission computed tomography (SPECT), the predictive value of BMIPP imaging in patients with angina pectoris was evaluated. One hundred seventy-four patients who underwent BMIPP imaging in our institution were aged 61.8±11 years. One hundred thirty-five patients had stable angina and 39 had unstable angina at the time of examination. Patients with previous myocardial infarction or myocardial disorders were excluded. Early and delayed images were acquired in BMIPP SPECT, and the images were analyzed visually. Cardiac events were classified into hard and soft events: the former consisted of cardiac death and nonfatal myocardial infarction, and the latter included coronary revascularization and heart failure. The findings of BMIPP imaging were normal in 82 patients and abnormal in 92. During follow-up of 15.5±9.5 months, hard events were observed in 4 patients and soft events in 53. In patients with normal BMIPP imaging, soft events were observed in nine patients, but no hard event was encountered. Furthermore, in patients with both normal BMIPP and stress thallium imagings, no cardiac event was observed during 2 years. In contrast, 4 hard events and 44 soft events occurred in patients with abnormal BMIPP imaging. Patients with abnormal BMIPP imaging had a higher incidence of soft events than those with normal BMIPP imaging, regardless of the type of angina (16/62 vs 3/73, p<0.0005 for stable angina; 28/30 vs 6/9, p<0.0001 for unstable angina). The finding of BMIPP imaging correlates well with the mid-term prognosis of patients with angina pectoris. Since BMIPP SPECT is performed without stress to the patient, this imaging modality is important in evaluating patients with stable or unstable angina. (author)

    Coronary revascularisation is the treatment of choice in patients with stable angina who have significant stenoses. From a pathophysiological point of view, however, mitigation of angina is to be expected only in the presence of reversible ischaemia. Therefore it was the aim of this study to examine the effect of revascularisation on stable angina in relation to the myocardial perfusion imaging (MPI) pattern prior to intervention. Three hundred and eighty-four patients (58.0±8.8 years) referred for angiography underwent MPI. Prior to MPI and at 2-year follow-up, patients were classified as having typical angina, atypical angina, non-cardiac chest pain or no pain, and the severity of chest pain was graded according to the Canadian Cardiovascular Society (CCS) criteria. The patients themselves estimated their pain on a visual analogue scale. Management was based on symptoms and angiographic findings, since the results of MPI were not communicated. Among the 240 patients who were not revascularised, 79% had typical or atypical angina at study entrance versus 40% at follow-up. In comparison, 93% of the 144 revascularised patients had typical or atypical angina before intervention versus only 36% at follow-up. This additional advantage of invasive therapy was present only in patients with reversible defects; revascularisation had no additional effect in patients with normal perfusion or irreversible defects. Similarly, additional, significant reductions in CCS class and visual analogue score were observed exclusively in patients with reversible defects. In patients referred for coronary angiography owing to known or suspected stable angina, revascularisation was significantly more effective than medical treatment exclusively in patients with reversible ischaemia.

    To evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris. Block randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina. The 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P0.05), while they were signifificantly better for KA in the CCSI and II subgroups (Pangina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).

    We evaluated 193 consecutive unstable angina patients by clinical features, hospital course and electrocardiography. All patients were managed medically. Of the 193 patients, 150 (78%) had a technetium-99m pyrophosphate (Tc-PYP) myocardial scintigram after hospitalization. Of these, 49 (33%) had positive scintigrams. At a follow-up of 24.9 +- 10.8 months after hospitalization, 16 of 49 patients (33%) with positive scintigrams died from cardiac causes, compared with six of 101 patients (6%) with negative scintigrams (p < 0.001). Of 49 patients with positive scintigrams, 11 (22%) had had nonfatal myocardial infarction at follow-up, compared with seven of 101 patients (7%) with negative scintigrams (p < 0.01). Age, duration of clinical coronary artery disease, continuing angina during hospitalization, ischemic ECG, cardiomegaly and a history of heart failure also correlated with cardiac death at follow-up. Ischemic ECG and a history of angina with a crescendo pattern also correlated with nonfatal infarction at follow-up. Patients with continuing angina, an ischemic ECG and a positive scintigram constituted a high-risk unstable angina subgroup, with a survival rate of 58% at 6 months, 47% at 12 months and 42% at 24 and 36 months. We conclude that the assessment of clinical features, hospital course, ECG and Tc-PYP scintigraphy may be useful in identifying high-risk unstable angina patients

  14. Intravascular stenting in the superior mesenteric artery for chronic abdominal angina.

    Science.gov (United States)

    Busquet, J

    1997-11-01

    Abdominal angina is an early clinical expression of occlusive mesenteric arterial insufficiency, a condition that requires aggressive treatment to prevent intestinal infarction. We report a case of chronic mesenteric ischemia in a young polyvascular man who had symptoms of abdominal angina. An aortic angiogram revealed a significant ostial stenosis of the superior mesenteric artery (SMA) associated with an occlusion of the inferior mesenteric artery. After predilation of the ostial portion of the SMA, significant residual stenosis remained. A balloon-expandable Palmaz P154 stent was deployed, restoring adequate luminal dimensions and blood flow. The patient was discharged after 2 days and remains asymptomatic at 5 months. Intraluminal stenting for treatment of mesenteric ischemia represents a viable alternative to surgical revascularization in selected cases.

    Full Text Available Refractory angina pectoris is defined as a chronic debilitating condition characterized by the presence of chronic anginal symptoms due to a severe obstructive and/or diffuse coronary artery disease that cannot be controlled by the combination of medical therapy and / or revascularization (percutaneous or surgical. In addition the presence of myocardial ischemia as a cause of the symptoms must have been documented. The coronary sinus Reducer (CSR is a recently introduced percutaneous device to treat patients with severe anginal symptoms refractory to optimal medical therapy and not amenable to conventional revascularization. The purpose of this review is to describe the current evidence from available studies measuring the clinical effect of the CSR implantation on the health and well-being of patients with refractory angina.

    Coronary angiography and the assessment of blood lipoproteins were carried out in 43 patients with recent (not more than three months old) angina. A rise in cholesterol above 270 mg/dl and/or triglycerids bove 200 mg/dl was demonstrated in 19. The level of α-cholesterol was below 35 mg/dl in 11 of 24 normolipidemic patients. The apoprotein B/apoprotein AI ratio was above 1.0 in 7 of 13 patients with normal cholesterol levels. Plasma phospholipid composition was disturbed in 4 of 6 patients with normal apoprotein B/apoprotein AI rations. Therefore atherogenic changes in plasma lipoprotein composition were found in 95% of patients with recent angina

    Selective intra-arterial digital substraction angiography (DSA) is important in the demonstration of the visceral abdominal vessels in angina-abdominalis patients. DSA allows to accurately determine the location of stenoses, vascular occlusions or plaque formations as does conventional angiography; in addition, it provides for simultaneous direct observation which is a major advantage over the conventional technique since suspected lesions can be better focussed in several planes.

    Seasonal peaks in cardiovascular disease incidence have been widely reported, suggesting weather has a role. The aim of our study was to determine the influence of climatic variables on angina pectoris hospital admissions. We correlated the daily number of angina cases admitted to a western Sicilian hospital over a period of 12 years and local weather conditions (temperature, humidity, wind force and direction, precipitation, sunny hours and atmospheric pressure) on a day-to-day basis. A total of 2459 consecutive patients were admitted over the period 1987-1998 (1562 men, 867 women; M/F - 1:8). A seasonal variation was found with a noticeable winter peak. The results of Multivariate Poisson analysis showed a significant association between the daily number of angina hospital admission, temperature, and humidity. Significant incidence relative ratios (95% confidence intervals/measure unit) were, in males, 0.988 (0.980-0.996) (p = 0.004) for minimal temperature, 0.990 (0.984-0.996) (p = 0.001) for maximal humidity, and 1.002 (1.000-1.004) (p = 0.045) for minimal humidity. The corresponding values in females were 0.973 (0.951-0.995) (p < 0.017) for maximal temperature and 1.024 (1.001-1.048) (p = 0.037) for minimal temperature. Environmental temperature and humidity may play an important role in the pathogenesis of angina, although it seems different according to the gender. These data may help to understand the mechanisms that trigger ischemic events and to better organize hospital assistance throughout the year.

    Oral Chinese proprietary medicine (CPM) is commonly used to treat angina pectoris, and many relevant systematic reviews/meta-analyses are available. However, these reviews have not been systematically summarized and evaluated. We conducted an overview of these reviews, and explored their methodological and reporting quality to inform both practice and further research. We included systematic reviews/meta-analyses on oral CPM in treating angina until March 2013 by searching PubMed, Embase, the Cochrane Library and four Chinese databases. We extracted data according to a pre-designed form, and assessed the methodological and reporting characteristics of the reviews in terms of AMSTAR and PRISMA respectively. Most of the data analyses were descriptive. 36 systematic reviews/meta-analyses involving over 82,105 participants with angina reviewing 13 kinds of oral CPM were included. The main outcomes assessed in the reviews were surrogate outcomes (34/36, 94.4%), adverse events (31/36, 86.1%), and symptoms (30/36, 83.3%). Six reviews (6/36, 16.7%) drew definitely positive conclusions, while the others suggested potential benefits in the symptoms, electrocardiogram, and adverse events. The overall methodological and reporting quality of the reviews was limited, with many serious flaws such as the lack of review protocol and incomprehensive literature searches. Though many systematic reviews/meta-analyses on oral CPM for angina suggested potential benefits or definitely positive effects, stakeholders should interpret the findings of these reviews with caution, considering the overall limited methodological and reporting quality. We recommend further studies should be appropriately conducted and systematic reviews reported according to PRISMA standard. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Traditional Chinese medicine (TCM) injection is widely used to treat angina pectoris in China. This overview aims to systematically summarize the general characteristics of systematic reviews (SRs) on TCM injection in treating angina, and assess the methodological and reporting quality of these reviews. We searched PubMed, Embase, the Cochrane Library and four Chinese databases from inception until March 2013. Data were extracted according to a preset form. The AMSTAR and PRISMA checklists were used to explore the methodological quality and reporting characteristics of included reviews, respectively. All data analyses were descriptive. 46 SRs involving over 57,463 participants with angina reviewing 23 kinds of TCM injections were included. The main outcomes evaluated in the reviews were symptoms (43/46, 93.5%), surrogate outcomes (42/46, 91.3%) and adverse events (41/46, 87.0%). Few reviews evaluated endpoints (7/46, 15.2%) and quality of life (1/46, 2.2%). One third of the reviews (16/46, 34.8%) drew definitely positive conclusions while the others (30/46, 65.2%) suggested potential benefits mainly in symptoms, electrocardiogram and adverse events. With many serious flaws such as lack of a protocol and inappropriate data synthesis, the overall methodological and reporting quality of the reviews was limited. While many SRs of TCM injection on the treatment of angina suggested potential benefits or definitely positive effects, stakeholders should not accept the findings of these reviews uncritically due to the limited methodological and reporting quality. Future SRs should be appropriately conducted and reported according to international standards such as AMSTAR and PRISMA, rather than published in large numbers.

    We performed BMIPP myocardial SPECT and Tl myocardial SPECT in patients with unstable angina (UAP) and stable effort angina (SAP), and compared the results for the two groups. Our subjects were 30 patients with the UAP and 25 patients with the SAP. The early and delayed images of the BMIPP were obtained with patients at rest. The early image of the Tl alone was obtained with patients at rest. We calculated severity score (SS) using the polar map based on SPECT short-axis image on the both myocardial SPECT. And, we calculated % uptake of the responsible coronary lesion and regional washout rate (WR) on myocardial SPECT with BMIPP. On coronary angiogram, no difference in % diameter stenosis was seen between the two groups. On myocardial SPECT with Tl, no difference in the SS was seen between the two groups. However, on myocardial SPECT with BMIPP, the SS was significantly higher score in the UAP group than in the SAP group. And, on myocardial SPECT with BMIPP, the % uptake and the WR were significant lower values in the UAP group than in the SAP group. Even if the two groups have almost the same level of myocardial perfusion disorder, the UAP group may have severer myocardial fatty-acid metabolic disorder than the SAP group, because the defects in BMIPP were significantly severer in the UAP group.

  9. Long-term use of short- and long-acting nitrates in stable angina pectoris.

    Science.gov (United States)

    Kosmicki, Marek Antoni

    2009-05-01

    Long-acting nitrates are effective antianginal drugs during initial treatment. However, their therapeutic value is compromised by the rapid development of tolerance during sustained therapy, which means that their clinical efficacy is decreased during long-term use. Sublingual nitroglycerin (NTG), a short-acting nitrate, is suitable for the immediate relief of angina. In patients with stable angina treated with oral long-acting nitrates, NTG maintains its full anti-ischemic effect both after initial oral ingestion and after intermittent long-term oral administration. However, NTG attenuates this effect during continuous treatment, when tolerance to oral nitrates occurs, and this is called cross-tolerance. In stable angina long-acting nitrates are considered third-line therapy because a nitrate-free interval is required to avoid the development of tolerance. Nitrates vary in their potential to induce the development of tolerance. During long-lasting nitrate therapy, except pentaerythritol tetranitrate (PETN), one can observe the development of reactive oxygen species (ROS) inside the muscular cell of a vessel wall, and these bind with nitric oxide (NO). This leads to decreased NO activity, thus, nitrate tolerance. PETN has no tendency to form ROS, and therefore during long-term PETN therapy, there is probably no tolerance or cross-tolerance, as during treatment with other nitrates.

None of them had myocardial infarction or cardiomyopathy. Thallium-201 myocardial scintigraphy and 12-lead ECG recording were performed during supine bicycle ergometer exercise. Perfusion defects in thallium-201 scintigrams in SPECT images were assessed during visual analysis by two observers. In the coronary angiograms obtained during intravenous infusion of nitroglycerin, the luminal diameter of 75% stenosis or less in the AHA classification was regarded as an insignificant organic stenosis. Myocardial perfusion defects in the thallium-201 scintigrams were detected in eight (25%) of the 32 patients. Six of these eight patients had variant angina documented during spontaneous attacks with ST elevations in standard 12-lead ECGs. Perfusion defects were demonstrated at the inferior or infero-posterior regions in six patients, one of whom had concomitant anteroseptal defect. The defects were not always accompanied by chest pain. All but one patient demonstrating inferior or inferoposterior defects showed ST depression in leads II, III and aV F on their ECGs, corresponding to inferior wall ischemia. The exception was a case with right bundle branch block. Thus, 25% of the patients with angina pectoris, who had no evidence of significant organic stenosis on their coronary angiograms, exhibited exercise-induced perfusion defects in their thallium-201 scintigrams. Coronary spasms might have caused myocardial ischemia in these patients. (author)

    Objective:To study the efficacy of fluoxetine combined with conventional drug treatment on unstable angina patients complicated with depression. Methods:120 cases of unstable angina patients with depression were randomly divided into two groups. The anti-depression group received fluoxetine combined with conventional drug therapy; the conventional group received conventional drug therapy. Then contents of monoamine neurotransmitters and their metabolites, antioxidants and inflammatory mediators of both groups were compared. Results:Serum monoamine neurotransmitters NE, 5-HT and HA levels of the anti-depression group were higher than those of the conventional group and metabolites 5-HIAA and HVA contents were lower than those of the conventional group; serum SOD, CAT, GSH and HSP-70 contents of the anti-depression group were higher than those of the conventional group, and hs-CRP, MMP9, MCP1 and HMGB1 contents were lower than those of the conventional group. Conclusion:Fluoxetine combined with conventional drug therapy can increase the contents of monoamine neurotransmitters and antioxidants, and reduce oxidative stress response and inflammatory response; it is an ideal method for treating unstable angina complicated with depression.

    The purpose of this study was to examine the rest thallium-201 perfusion pattern during angina-free periods in 40 patients with rest angina pectoris secondary to coronary artery disease (greater than or equal to 70% diameter narrowing). Seventeen patients had previous Q wave myocardial infarction. The perfusion defects were considered fixed or reversible, depending on the absence or presence of redistribution in the 4-hour delayed images. There were 40 perfusion defects (26 fixed and 14 reversible) in 27 patients whereas 13 patients had normal scans. Reversible perfusion defects were present in 10 patients (25%). Of the 26 fixed perfusion defects, 17 did not have corresponding Q waves. Occluded vessels (63%) had more perfusion defects than vessels with subtotal occlusion (30%) (p less than 0.01). The perfusion defect size was larger in patients with lower ejection fraction than in patients with higher ejection fraction. We conclude: (1) perfusion defects are common in patients with rest angina and are reversible in 25% of patients indicating reduced regional coronary blood flow; (2) the degree of stenosis affects the presence of perfusion defect; (3) fixed defects may be present without corresponding Q waves; and (4) global left ventricular function is related to the size of perfusion defects

    This paper assessed the evidence of Panax notoginseng preparations in patients suffering from UAP using meta-analysis and systematic review methods. Methods were according to the Cochrane Handbook and analysed using Revman 5.3. A search of PubMed, Cochrane Library, Embase, MEDLINE, Chinese national knowledge infrastructure (CNKI), Vip information database, Wanfang data and Chinese Biomedical Literature Database (SinoMed) was conducted to identify randomized controlled trials (RCTs) of P. notoginseng preparations on UAP regardless of blinding, sex and language. The outcomes include all-cause mortality, cardiac mortality, cardiovascular events, UAP symptoms, improvement of electrocardiogram and adverse events. Eighteen RCTs including 1828 patients were identified. The level of reporting is generally poor. Among 18 studies, 16 studies were prescribed P. notoginseng injections, and two studies were oral P. notoginseng preparations. Reduction of cardiovascular events (RR:0.35;95% CI:0.13 to 0.94), alleviation of angina pectoris symptoms (RR:1.23;95% CI 1.18 to 1.29), improvement of ECG (RR:1.22;95% CI 1.15 to 1.28) and reduced frequency of angina pectoris (MD:-1.48; 95% CI -2.49 to -0.48) were observed. Cardiac mortality and duration of angina pectoris were not statistically significant. Panax notoginseng is beneficial to UAP patients; the results of these reviews may have important implications to clinical work. Copyright © 2017 John Wiley & Sons, Ltd.

    To evaluate the beneficial and adverse effects of breviscapine injection in combination with Western medicine on the treatment of patients with angina pectoris. The Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, the China National Knowledge Infrastructure, the Wanfang Database, the Chongqing VIP Information Database and the China Biomedical Database were searched to identify randomized clinical trials (RCTs) that evaluated the effects of Western medicine compared to breviscapine injection plus Western medicine on angina pectoris patients. The included studies were analyzed using RevMan 5.1.0 software. The literature search yielded 460 studies, wherein 16 studies matched the selection criteria. The results showed that combined therapy using Breviscapine plus Western medicine was superior to Western medicine alone for improving angina pectoris symptoms (OR=3.77, 95% Cl: 2.76~5.15) and also resulted in increased electrocardiogram (ECG) improvement (OR=2.77, 95% Cl: 2.16~3.53). The current evidence suggests that Breviscapine plus Western medicine achieved a superior therapeutic effect compared to Western medicine alone.

Los cursos que se consideraron fueron: Introducción a la pedagogía, Didáctica General, Principios de Curriculum, Investigación Educativa, Psicología Educativa, Ciencias en la Educación Primaria, Práctica Docente y Evaluación de los Aprendizajes. La investigación se orientó con el siguiente problema general: ¿Cuáles son las estrategias didácticas en la enseñanza del área pedagógica, aplicadas en la formación inicial de docentes para la Educación Primaria en la Sede de Occidente de la Universidad de Costa Rica? En el estudio se analizaron y se confrontaron los programas de los cursos mencionados, considerando las estrategias didácticas que se aplican para su desarrollo, según el criterio de docentes y alumnos. En este análisis se describe la coherencia entre estos dos aspectos, las tendencias pedagógicas que subyacen en las estrategias didácticas y las innovaciones que se desarrollan como parte de los procesos de enseñanza y aprendizaje. El proceso investigativo demuestra que el plan de estudio considera como referencia pedagógica un enfoque humanista; mientras que los programas de los cursos y la práctica docente no logran desligarse de la didáctica tradicional, con tendencia a incorporar aspectos del Constructivismo y de la Pedagogía Crítica. En el estudio no se logró apreciar la incorporación de estrategias didácticas innovadoras de manera significativa.

    Full Text Available La atención primaria en España ha pasado de una etapa de desarrollo florido, en la década de los ochenta, a otra de estancamiento en los noventa, caracterizada por la escasa creatividad, por la rutinización de las tareas y por la puesta en marcha de carteras de servicios y contratos programa. Por otra parte, los recientes cambios en la orientación de la investigación promovida desde la administración sanitaria, a favor de la investigación básica y en detrimento de la investigación en servicios y la epidemiología clínica, contrastan con la importancia de la atención primaria como ámbito natural de abordaje de numerosos agentes causales y prácticas de riesgo para la salud. A pesar de estas limitaciones, la cultura de la investigación ya se ha instalado en un buen número de centros de salud y de farmacias, y la investigación en atención primaria ha ido teniendo una mayor presencia en las revistas científicas. Sin embargo, es necesario gestionar la investigación, también desde las estructuras de atención primaria, de manera específica y diferenciada, favoreciendo la priorización, la evaluación y la responsabilidad mediante fórmulas organizativas flexibles y sistemas de información específicos. Ello debería incluir fórmulas de contratación y de relación laboral flexibles, que permitan la dedicación a la investigación, siquiera a tiempo parcial, así como modelos de carrera profesional que reconozcan las actividades de investigación y docencia. Las asociaciones científicas y profesionales de la atención primaria tienen ante sí el reto de mantener proyectos de investigación activos, incrementar su presencia entre los profesionales, emitir su opinión ante los problemas del sector y reforzar su organización y comunicación.Primary care in Spain has undergone a burgeoning phase in the 80's, followed by a decade of stagnation in the 90's, with little creativity, a routinisation of tasks, and the set up of service

    To assess the safety and efficacy of extracorporeal shockwave myocardial revascularization (ESMR) therapy in treating patients with refractory angina pectoris. A single-arm multicenter prospective trial to assess safety and efficacy of the ESMR therapy in patients with refractory angina (class III/IV angina) was performed. Screening exercise treadmill tests and pharmacological single-photon emission computed tomography (SPECT) were performed for all patients to assess exercise capacity and ischemic burden. Patients were treated with 9 sessions of ESMR to ischemic areas over 9 weeks. Efficacy end points were exercise capacity by using treadmill test as well as ischemic burden on pharmacological SPECT at 4 months after the last ESMR treatment. Safety measures included electrocardiography, echocardiography, troponin, creatine kinase, and brain natriuretic peptide testing, and pain questionnaires. Fifteen patients with medically refractory angina and no revascularization options were enrolled. There was a statistically significant mean increase of 122.3±156.9 seconds (38% increase compared with baseline; P=.01) in exercise treadmill time from baseline (319.8±157.2 seconds) to last follow-up after the ESMR treatment (422.1±183.3 seconds). There was no improvement in the summed stress perfusion scores after pharmacologically induced stress SPECT at 4 months after the last ESMR treatment in comparison to that at screening; however, SPECT summed stress score revealed that untreated areas had greater progression in ischemic burden vs treated areas (3.69±6.2 vs 0.31±4.5; P=.03). There was no significant change in the mean summed echo score from baseline to posttreatment (0.4±5.1; P=.70). The ESMR therapy was performed safely without any adverse events in electrocardiography, echocardiography, troponins, creatine kinase, or brain natriuretic peptide. Pain during the ESMR treatment was minimal (a score of 0.5±1.2 to 1.1±1.2 out of 10). In this multicenter feasibility

    OBJECTIVE: To ascertain the risk of acute myocardial infarction, invasive cardiac procedures, and mortality among patients with newly diagnosed angina over five years. DESIGN: Incident cohort study of patients with primary care data linked to secondary care and mortality data. SETTING: 40 primary care practices in Scotland. PARTICIPANTS: 1785 patients with a diagnosis of angina as their first manifestation of ischaemic heart disease, 1 January 1998 to 31 December 2001. MAIN OUTCOME MEASURES: Adjusted hazard ratios for acute myocardial infarction, coronary artery bypass grafting, percutaneous transluminal coronary angioplasty, death from ischaemic heart disease, and all cause mortality, adjusted for demographics, lifestyle risk factors, and comorbidity at cohort entry. RESULTS: Mean age was 62.3 (SD 11.3). Male sex was associated with an increased risk of acute myocardial infarction (hazard ratio 2.01, 95% confidence interval 1.35 to 2.97), death from ischaemic heart disease (2.80, 1.73 to 4.53), and all cause mortality (1.82, 1.33 to 2.49). Increasing age was associated with acute myocardial infarction (1.04, 1.02 to 1.06, per year of age increase), death from ischaemic heart disease (1.09, 1.06 to 1.11, per year of age increase), and all cause mortality (1.09, 1.07 to 1.11, per year of age increase). Smoking was associated with subsequent acute myocardial infarction (1.94, 1.31 to 2.89), death from ischaemic heart disease (2.12, 1.32 to 3.39), and all cause mortality (2.11, 1.52 to 2.95). Obesity was associated with death from ischaemic heart disease (2.01, 1.17 to 3.45) and all cause mortality (2.20, 1.52 to 3.19). Previous stroke was associated with all cause mortality (1.78, 1.13 to 2.80) and chronic kidney disease with death from ischaemic heart disease (5.72, 1.74 to 18.79). Men were more likely than women to have coronary artery bypass grafting or percutaneous transluminal coronary angioplasty after a diagnosis of angina; older people were less likely to

    Ranolazine is an antianginal agent that was approved in the EU in 2008 as an add-on therapy for symptomatic chronic angina pectoris treatment in patients who are inadequately controlled by, or are intolerant to, first-line antianginal therapies. These patients' quality of life is significantly affected by more frequent angina events, which increase the risk of revascularization. To assess the cost-utility of ranolazine versus placebo as an add-on therapy for the symptomatic treatment of patients with chronic angina pectoris in Spain. A decision tree model with 1-year time horizon was designed. Transition probabilities and utility values for different angina frequencies were obtained from the literature. Costs were obtained from Spanish official DRGs for patients with chronic angina pectoris. We calculated the incremental cost-utility ratio of using ranolazine compared with a placebo. Sensitivity analyses, by means of Monte Carlo simulations, were performed. Acceptability curves and expected value of perfect information were calculated. The incremental cost-utility ratio was €8,455 per quality-adjusted life-year (QALY) per patient in Spain. Sensitivity analyses showed that if the decision makers' willingness to pay is €15,000 per QALY, the treatment with ranolazine will be cost effective at a 95 % level of confidence. The incremental cost-utility ratio is particularly sensitive to changes in utility values of those non-hospitalized patients with mild or moderate angina frequency. Ranolazine is a highly efficient add-on therapy for the symptomatic treatment of chronic angina pectoris in patients who are inadequately controlled by, or intolerant to, first-line antianginal therapies in Spain.

    Full Text Available Fundamentos: La hiperfrecuentación es un fenómeno preocupante para los sistemas sanitarios occidentales, por la gran carga de trabajo que genera y sus altos costes materiales y humanos. El objetivo de este trabajo es estudiar los significados, categorías y prácticas que las médicas y médicos de Atención Primaria vivencian en torno a la hiperfrecuentación. Métodos: Estudio cualitativo basado en una aproximación sociosubjetiva, a través de entrevistas en profundidad (ocho entrevistas a médicos/as de Atención Primaria de la Comunidad de Madrid. El material discursivo se analizó desde una perspectiva pragmatista. Resultados: La figura del médico de Atención Primaria se encuentra en la intersección de lógicas profesionales-institucionales contradictorias, lo que genera niveles altos de malestar profesional. Los aspectos sociales y psicológicos aparecen de forma confusa en relación con la consideración de todo aquello que no tiene que ver con lo físico como ajeno al ámbito de actuación de la medicina. La hiperfrecuentación resulta problemática porque se sitúa en el centro de la dicotomía signo-síntoma, su manejo requiere mucho tiempo, precisa de un abordaje integral, e imposibilita el cumplimiento del rol médico como profesional que diagnostica e instaura un tratamiento etiológico. Estas dificultades terminan por traducirse en conflictos en la relación profesional-paciente. Conclusiones: Los significados relativos a la hiperfrecuentación van a variar notablemente en función de las posiciones sociosubjetivas, por lo que abordajes como el que aquí se propone ayudan a comprender la complejidad de una problemática que se construye en el seno de las relaciones entre sujetos particulares, atravesados por dinámicas institucionales, conflictos laborales, trayectorias profesionales e ideologías diversas.

MÉTODO: El análisis de accesibilidad espacial mediante sistemas de información geográfica (SIG requirió de tres aspectos: la población sin cobertura médica, la distribución de los CAPS y la red de transporte público que los conecta. RESULTADOS: La construcción de indicadores de demanda (real, potencial y diferencial y el análisis de los factores territoriales que intervienen en la movilidad de la población permitieron caracterizar los CAPS en relación a su entorno, contribuyendo al análisis, tanto en una perspectiva local como regional, y a la detección de diferentes zonas según niveles de conectividad a escala regional. CONCLUSIONES: Los indicadores construidos en el entorno SIG fueron de gran utilidad para el análisis de accesibilidad a los CAPS por la población vulnerable. La zonificación del territorio contribuyó a identificar inequidades al diferenciar áreas de demanda no satisfecha y la fragmentación de la conectividad espacial entre CAPS y transporte público.

  11. La competencia digital de la Generación Z: claves para su introducción curricular en la Educación Primaria

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available La convergencia mediática y el uso masivo de dispositivos conectados a Internet, rasgos distintivos de la sociedad actual, provocan cambios en el modo en el que las nuevas generaciones aprenden y acceden al conocimiento. Además, emergen nuevas competencias, las digitales, que la Generación Z necesita para afrontar los retos de una sociedad digitalizada. El estudio presentado, de corte cuantitativo, con una muestra de 678 alumnos de Educación Primaria, pretende aportar evidencias empíricas sobre el nivel de competencia digital del alumnado perteneciente a dicha generación. Los resultados revelan que no adquieren habilidades digitales de forma inherente sino que precisan de educación al respecto, atisbándose el peligro de una brecha digital, no por uso o acceso a ellas, sino por falta de competencia. La ausencia de diferencia significativa en el nivel general de competencia digital entre el alumnado de diferentes cursos de la etapa de Educación Primaria refleja que, en cierta medida, ese nivel se adquiere más por convivencia con las TIC en contextos informales que por un adecuado desarrollo en el contexto escolar que potencie gradual y progresivamente su adquisición.

    EntreMed has licensed the worldwide rights to the angiogenesis inhibitor Endostatin, a 20 kDa C-terminal fragment of collagen XVIII, from the Children's Hospital of Boston, a teaching affiliate of Harvard Medical School. It is being developed as a potential cancer treatment and may also be useful in certain types of blindness and arthritis [227427]. EntreMed filed an IND for Endostatin in June 1999 [334125] and as of September 1999, phase I trials were underway [341462]. As of April 2000, the company had initiated plans for testing low doses of Endostatin in cancer patients using continuous infusion and sc administration in a further phase I study to be conducted in Europe [361594]. A phase I trial of Endostatin which will evaluate the safety and efficacy of Endostatin at a range of doses in no more than 100 cancer patients has been initiated. The trial will take place at the University of Texas MD Anderson Medical Center and the University of Wisconsin Cancer Center in Madison. The National Cancer Center will be sponsoring the trial, which is expected to be completed in late 2000. As of March 2000, there had been no serious adverse events attributable to Endostatin administration. The first report from this trial is expected in autumn 2000 [341462], [366312]. The mechanism of action for Endostatin remains unclear, although reports from the 91st AACR Meeting in April 2000 showed that recombinant human endostatin bound to a number of tropomyosin cDNAs in a library screen [362039]. In preclinical studies, repeated administration of Endostatin consistently shrank primary tumors and did not produce any drug resistance. In mice, a variety of tumors which had progressed to 1 to 2% of total body weight, regressed to microscopic, dormant lesions following Endostatin treatment [231418], [231470], [270673]. Types of cancers which respond to Endostatin include lung, skin, vascular and fibrosarcomas. Toxicology studies in cynomolgus monkeys showed that bolus injections of

    Full Text Available La acción tutorial constituye un proceso, enmarcado dentro de la orientación educativa, que complementa a la acción docente. No tiene sentido entenderla como una serie de actuaciones independientes y puntales entre sí, sino como un conjunto de intenciones y actividades colectivas y coordinadas, que involucra a todos los miembros de la comunidad educativa: profesorado, alumnado y familias. Por este motivo, tan importante es conocer los posibles recursos para ponerla en marcha como la manera de programar y planificar su desarrollo. El propósito del estudio es conocer el grado de desarrollo de la acción tutorial del profesorado de Educación Infantil y Primaria. La muestra estuvo compuesta por 50 docentes tutores de diferentes centros de la provincia de Granada y se utilizó un cuestionario diseñado ad hoc. Una de las conclusiones que podemos extraer es que el profesorado‐tutor participante ofrece más importancia a las tareas académicas que tienen lugar dentro del aula de entre aquellas que tienen relación con la acción tutorial. Las dificultades que normalmente encuentran los tutores y tutoras en la realización de su labor son la falta de tiempo para completar todas las actuaciones de carácter tutorial que se le exige.

    In the absence of previous international comparisons, we sought to systematically evaluate, across time and participant age, the sex ratio in angina prevalence in countries that differ widely in the rate of mortality due to myocardial infarction. We searched MEDLINE and EMBASE until February 2006 for healthy population studies published in any language that reported the prevalence of angina (Rose questionnaire) in women and men. We obtained myocardial infarction mortality rates from the World Health Organization. A total of 74 reports of 13,331 angina cases in women and 11,511 cases in men from 31 countries were included. Angina prevalence varied widely across populations, from 0.73% to 14.4% (population weighted mean 6.7%) in women and from 0.76% to 15.1% (population weighted mean 5.7%) in men, and was strongly correlated within populations between the sexes (r=0.80, Pethnic groups than among whites. This sex ratio did not differ significantly by participant's age, the year the survey began, or the sex ratio for mortality due to myocardial infarction. Over time and at different ages, independent of diagnostic and treatment practices, women have a similar or slightly higher prevalence of angina than men across countries with widely differing myocardial infarction mortality rates.

An extensive search of 6 medical databases was performed up to August 2013. Randomized controlled trials (RCTs involving XST alone or combined with conventional drugs versus conventional drugs were included. A meta-analysis of reduction of angina symptoms and electrocardiogram (ECG improvement was performed to evaluate the effects of XST on UA. Results. After researching, a total of 6 RCTs with 716 participants were included. Our review showed that XST combined with conventional drugs had significant effect on relieving angina symptoms (RR: 1.14 [1.07,1.22]; P=0.0001 and improving ECG (RR: 1.26 [1.12,1.42]; P=0.0001 compared with conventional drugs alone. Conclusions. XST appears to have beneficial effects on improvement of ECG, reduction of angina symptoms, and decreasing the frequency and duration of angina attack in participants with UA. However, the findings should be interpreted with caution due to the poor methodological quality of the included trials.

    2014-03-28

    To compare psychological and pain-related characteristics of patients with chronic pain and patients with refractory angina pectoris who had been treated with spinal cord stimulation (SCS) therapy. Twenty-four patients receiving SCS therapy were interviewed. Four psychological variables were assessed using standardised questionnaires for pain catastrophising, health locus of control, anxiety sensitivity, and self-efficacy. Patients also completed the revised version of the Short-Form McGill Pain Questionnaire, the Short-Form Health Survey, and self-reported measures of global perceived effect, pain, functionality, and satisfaction with SCS therapy. Most patients reported improvements in pain, functionality, and improvement overall. Some health locus of control dimensions were significantly higher for the angina group than the chronic pain group, and chronic angina patients reported significantly lower levels of intermittent pain. Virtually all patients reported being satisfied with SCS therapy. Most self-rated psychological and pain-related characteristics were no different between the two groups, which gives some support to the view that refractory angina is a form of chronic pain. The results also add to evidence supporting the use of SCS therapy for refractory angina pectoris; however, differences observed on a few variables may indicate points of focus for the assessment and treatment of such patients.

    This study was undertaken to assess the diagnostic value of resting 123 I-BMIPP scintigraphy in patients with effort angina pectoris. One hundred and four patients underwent scintigraphic and angiographic examinations. The subsets of the patients were stable effort angina pectoris (stable type) in 27 cases, new onset of effort angina pectoris (new onset type) in 21 cases, and worsening effort angina pectoris (worsening type) in 35 cases. The remaining 21 cases were subjects without evidences of coronary artery disease (non-CAD). 123 I-BMIPP was injected under resting and pain free condition, then data for single photon emission tomography (SPECT) were acquired. The positive regional 123 I-BMIPP defects in three coronary territories were visually judged on the tomographic images. The overall sensitivity to diagnose the patients was 62.6% (52/83) and the overall specificity to exclude non-CAD subjects was 95.2% (20/21). The detection rate in each subset of the disease was 48.1% (13/27) in stable type, 47.6% (10/21) in new onset type and 77.1% (27/35) in worsening type (p 123 I-BMIPP scintigraphy was therefore valuable in diagnosing patients with effort angina pectoris and involved coronary arteries especially in the subset of patients with worsening type.

    Full Text Available Smoking is a major risk factor in patients with angina pectoris. Interventions that facilitate the rejection of it are an important part of the treatment. Aim. To analyze the cost effectiveness of the partial agonist of nicotinic receptors, varenicline, in patients with angina who require cardiac interventions. Material and methods. The estimation was conducted using a Markov model based on the results of clinical trials and epidemiological studies. The cost of treatment of complications were calculated on the basis of compulsory medical insurance rates for St. Petersburg in 2011. Results. The varenicline therapy in 70-year-old patients before cardiac surgery reduces hospital mortality at an extremely high cost-effectiveness (the cost of preventing one death - 148.8 thousand rubles. The cost/effectiveness ratio in the analysis for the period of survival of patients in this situation was 31.3 thousand rubles for 1 additional year of life. Life expectancy will be increased by an average of 0.147 years. Analysis for the period of survival of 50-year-old patients has shown that in patients after cardiac surgery cost-effectiveness of varenicline is extremely high (in the analysis from the perspective of the health care system the cost/effectiveness ratio was 36.0 thousand rubles for 1 additional year of life, in the analysis, taking into account the social perspective – 17.9 thousand rubles for 1 additional year of life. Increase in the life expectancy of 50 year-old patients will be 0.291 year in average. Conclusion. Varenicline therapy of patients with angina pectoris is the economy before cardiac surgery , and after their execution, and this applies not only young, but older patients. The desirability of varenicline including to federal and regional programs to reduce cardiovascular morbidity and mortality is shown.

    Objective: To examine the effect of enhanced external counterpulsation (EECP) on depression in patients with refractory angina pectoris (Canadian Cardiovascular Society class 2–4). Method: The study was a prospective observational investigation with a 2-month control period preceding the EECP therapy (to minimize a possible effect of the regression-toward-the-mean phenomenon). The patients were examined 2 months before and just before EECP and just after, 3 months after, and 12 months after EECP. Depression was assessed using the Major Depression Inventory and the ICD-10. During EECP, 3 sets of cuffs were fastened around the lower extremities and were inflated sequentially to a pressure of 260 mm Hg in each diastole for 60 minutes 5 days a week for 7 weeks (35 sessions). The study was conducted at a regional hospital in Denmark from May 2006 to January 2011. Results: Fifty patients with angina pectoris and an abnormal coronary angiography, with no possibility for revascularization, were included (72% men, mean age of 63 years) between May 2006 and January 2011. The prevalence of depression before EECP was 18%, just after was 2%, 3 months after was 2%, and 12 months after was 4% (P = .013). The depressive state was more severe at a lower age (P = .016). No significant predictors of effect of EECP on depression were found (P > .05), and no association was detected between decline in depressive state and chest pain (P > .05). Conclusions: The study indicates that EECP is an effective treatment for depression in patients with refractory angina pectoris, that depression is more severe in younger patients, and that the effect of EECP on depression is not related to the effect on chest pain.

    Lipid metabolites are indispensable regulators of physiological and pathological processes, including atherosclerosis and coronary artery disease (CAD). However, the complex changes in lipid metabolites and metabolism that occur in patients with these conditions are incompletely understood. We performed lipid profiling to identify alterations in lipid metabolism in patients with angina and myocardial infarction (MI). Global lipid profiling was applied to serum samples from patients with CAD (angina and MI) and age-, sex-, and body mass index-matched healthy subjects using ultra-performance liquid chromatography/quadruple time-of-flight mass spectrometry and multivariate statistical analysis. A multivariate analysis showed a clear separation between the patients with CAD and normal controls. Lysophosphatidylcholine (lysoPC) and lysophosphatidylethanolamine (lysoPE) species containing unsaturated fatty acids and free fatty acids were associated with an increased risk of CAD, whereas species of lysoPC and lyso-alkyl PC containing saturated fatty acids were associated with a decreased risk. Additionally, PC species containing palmitic acid, diacylglycerol, sphingomyelin, and ceramide were associated with an increased risk of MI, whereas PE-plasmalogen and phosphatidylinositol species were associated with a decreased risk. In MI patients, we found strong positive correlation between lipid metabolites related to the sphingolipid pathway, sphingomyelin, and ceramide and acute inflammatory markers (high-sensitivity C-reactive protein). The results of this study demonstrate altered signatures in lipid metabolism in patients with angina or MI. Lipidomic profiling could provide the information to identity the specific lipid metabolites under the presence of disturbed metabolic pathways in patients with CAD.

    Data comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris. One hundred seventy-seven patients with significant coronary artery stenosis were randomly assigned to either the PCI group (n=90) or the OMT group (n=87). The primary outcome was a composite of major adverse events in the 1-year follow-up period that included cardiovascular death, non-fatal myocardial infarction, coronary revascularization, and stroke. Major adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death [hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041-5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039-4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057-14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106-0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035-0.703, p=0.016). Elective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT.

    This paper demonstrates the basic properties in the systems most commonly considered for costing treatments in the Danish hospitals. The differences between the traditional charge system, the DRG system and the ABC system are analysed, and difficulties encountered in comparing these systems are discussed. A sample of patients diagnosed with stable angina pectoris (SAP) at Odense University Hospital was used to compare the three systems when costing an entire treatment path, costing single hospitalisations and studying the effects of length of stay. Furthermore, it is illustrated that the main idea behind each system is reflected in how the systems over- or underestimate costs. Implications when managing the hospitals, particularly reimbursement, are discussed.

    Myocardial scintigraphy with thallium-201 is a new, non-invasive diagnostic method by means of which on special indications ischaemic heart diseases may be demonstrated. The case history is described of a man with hypertrophic cardiomyopathy and angina pectoris. The electrocardiogram at rest was affected by the cardiomyopathy to such a degree that the interpretation of the ST-T segment during effort was not reliable. Scintigraphy revealed transient ischaemia. A bypass operation was carried out and post-operatively, the improved myocardial perfusion could be confirmed by myocardial scintigraphy. (Auth.)

    Paresthesia-free stimulation such as high frequency and burst have been demonstrated as effective therapies for neuropathic pain. The aim of this meta-analysis was to evaluate the efficacy and safety of conventional spinal cord stimulation (SCS) in the treatment of refractory angina pectoris (RAP). Relevant randomized controlled trials that investigated SCS for patients with RAP were comprehensively searched in Medline, Pubmed, Embase, and Cochrane Library. Five meta-analyses were performed examining the changes in Canadian Cardiovascular Society classes, exercise time, Visual Analog Scale (VAS) scores of pain, Seattle Angina Questionnaire, and nitroglycerin use in RAP patients after SCS therapy. We analyzed standardized mean differences (MD) and 95% confidence intervals (CIs) for each outcome by Review Manager 5.0 and STATA 12.0. A total of 12 randomized controlled trials involving 476 RAP patients were identified. A trend of reduction in the angina frequency (MD=-9.03, 95% CI, -15.70 to -2.36) and nitroglycerin consumption (MD=-0.64, 95% CI, -0.84 to -0.45) could be observed in the SCS group. Compared with the control group, SCS showed benefit on increasing exercise time (MD=0.49, 95% CI, 0.13-0.85) and treatment satisfaction (MD=6.87, 95% CI, 2.07-11.66) with decreased VAS scores of pain (MD=-0.50, 95% CI, -0.81 to -0.20) and disease perception (MD=-8.34, 95% CI, -14.45 to -2.23). However, the result did not reach the significance level in terms of physical limitation (95% CI, -8.75 to 3.38; P=0.39) or angina stability (95% CI, -7.55 to 3.67; P=0.50). The current meta-analysis suggested that SCS was a potential alternative in the treatment of PAP patients. Further investigation for finding the appropriate intensity of stimulation is required before this treatment should be widely recommended and applied.

  1. Percutaneous coronary intervention for poor coronary microcirculation reperfusion of patients with stable angina pectoris.

    Percutaneous coronary intervention (PCI) has been extensively applied to repair the forward flow of diseased coronary artery and can achieve significant curative results. However, some patients with acute myocardial infarction (AMI) develop non-perfusion or poor perfusion of cardiac muscle tissue after PCI, which increases the incidence of cardiovascular events and the death rate. PCI can dredge narrowed or infarct-related artery (IRA) and thus induce full reperfusion of ischemic myocardium. It is found in practice that some cases of AMI still have no perfusion or poor perfusion in myocardial tissue even though coronary angiography suggests opened coronary artery after PCI, which increases the incidence of vascular events and mortality. Therefore, to explore the detailed mechanism of PCI in treating coronary microcirculation of patients with stable angina pectoris, we selected 140 patients with stable angina pectoris for PCI, observing the index of microcirculatory resistance (IMR) of descending branch and changes of myocardial injury markers and left ventricular systolic function, and made a subgroup analysis based on the correlation between clinical indexes, IMR and other variables of diabetic and non-diabetic patients, PCI-related and non-PCI-related myocardial infarction patients. The results suggest that IMR of anterior descending branch after PCI was higher compared to that before PCI, and the difference was significant (P less than 0.05); creatine kinase-MB (CK-MB), myohemoglobin and high sensitive troponin T were all increased after PCI, and the difference was also significant (P less than 0.05); brain natriuretic peptide (BNP) level became higher after PCI, with significant difference (P less than 0.05); left ventricular ejection fraction (LVEF) declined after PCI, and the difference before and after PCI was statistically significant (P less than 0.05). Moreover, subgroup analysis results of the three groups all demonstrated statistically significant

    Full Text Available Ludwig's angina is potentially lethal, rapidly spreading cellulitis of the floor of mouth and neck. The anticipated difficult airway becomes even more challenging when it occurs in children. In children, the larynx is positioned relatively higher in the neck, and one does not have the option for blind nasal intubation or awake fiberoptic, which otherwise is the technique of choice in adult patients. We present the clinical course of 16 children and highlight various problems encountered during the anesthetic management of six children who required emergency surgical drainage under general anesthesia.

    Full Text Available Prinzmetal angina or vasospastic angina is a clinical phenomenon that is often transient and self-resolving. Clinically it is associated with ST elevations on the electrocardiogram, and initially it may be difficult to differentiate from an acute myocardial infarction. The vasospasm induced in this setting occurs in normal or mildly to moderately diseased vessels and can be triggered by a number of etiologies including smoking, changes in autonomic activity, or drug ingestion. While the ischemia induced is usually transient, myocardial infarction and life-threatening arrhythmias can occur in 25% of cases. We present the case of a 65-year-old female where repetitive intermittent coronary vasospasm culminated in transmural infarction in the setting of gastrointestinal bleeding. This case highlights the mortality associated with prinzmetal angina and the importance of recognizing the underlying etiology.

    2010-10-01

    Full Text Available Abstract Background Exercise training has been shown to reduce angina and promote collateral vessel development in patients with coronary artery disease. However, the mechanism whereby exercise exerts these beneficial effects is unclear. There has been increasing interest in the use of whole genome peripheral blood gene expression in a wide range of conditions to attempt to identify both novel mechanisms of disease and transcriptional biomarkers. This protocol describes a study in which we will assess the effect of a structured exercise programme on peripheral blood gene expression in patients with stable angina, and correlate this with changes in angina level, anxiety, depression, and exercise capacity. Methods/Design Sixty patients with stable angina will be recruited and randomised 1:1 to exercise training or conventional care. Patients randomised to exercise training will attend an exercise physiology laboratory up to three times weekly for supervised aerobic interval training sessions of one hour in total duration. Patients will undergo assessments of angina, anxiety, depression, and peripheral blood gene expression at baseline, after six and twelve weeks of training, and twelve weeks after formal exercise training ceases. Discussion This study will provide comprehensive data on the effect of exercise training on peripheral blood gene expression in patients with angina. By correlating this with improvement in angina status we will identify candidate peripheral blood transcriptional markers predictive of improvements in angina level in response to exercise training.

    Full Text Available Abstract Objective: In contrast to unstable angina, optimal therapy in patients with stable angina is debated. Our aim was to evaluate the outcomes of patients with stable angina scheduled for isolated coronary artery bypass grafts and the effect of preoperative use of beta-blockers. Overall and cardiovascular survivals were our primary outcome. Operative mortality and postoperative complications along with subgroup analysis of diabetic patients were our secondary outcomes. Methods: Retrospective evaluation of patients with stable angina scheduled for isolated coronary artery bypass grafts was included. Pre- and postoperative variables were extracted from the institution database. Survival was obtained from the National Registry. Results: We included 282 patients with stable angina, with a mean age of 65.6±9.5 years. 26.6% were female and 38.7% had diabetes. Three-vessel disease was present in 76.6% of patients. Previous beta-blocker treatment was evident in 69.9% of patients. 10-year overall survival in the whole population was 60.5% (95% confidence interval [CI]: 50.3-70.7%. Operative mortality during the study period was 3.5%. Patients with preoperative use of beta-blocker therapy had better overall survival (9.0 years, 95%CI: 8.6-9.5 than those without treatment (7.9 years, 95%CI: 7.1-8.8 years; P=0.048. Predictors for overall survival were: hypertension, diabetes, and age. Predictors for cardiovascular survival in diabetic patients were: beta-blocker use, gender, and age. Conclusion: Coronary artery bypass grafts surgery in patients with stable angina carries low operative mortality, postoperative complications, and excellent long-term cardiovascular survival. The preoperative use of beta-blockers in diabetic patients is associated with better cardiovascular survival after coronary artery bypass grafts.

    We sought to investigate the potential role of elevated levels of thrombopoietin (TPO) in platelet activation during unstable angina (UA). Thrombopoietin is a humoral growth factor that does not induce platelet aggregation per se, but primes platelet activation in response to several agonists. No data concerning its contribution to platelet function abnormalities described in patients with UA are available. We studied 15 patients with UA and, as controls, 15 patients with stable angina (SA) and 15 healthy subjects. We measured TPO and C-reactive protein (CRP), as well as monocyte-platelet binding and the platelet expression of P-selectin and of the TPO receptor, c-Mpl. The priming activity of patient or control plasma on platelet aggregation and monocyte-platelet binding and the role of TPO in this effect also were studied. Patients with UA showed higher circulating TPO levels, as well as increased monocyte-platelet binding, platelet P-selectin expression, and CRP levels, than those with SA and healthy control subjects. The UA patients also showed reduced platelet expression of the TPO receptor, c-Mpl. In vitro, the plasma from UA patients, but not from SA patients or healthy controls, primed platelet aggregation and monocyte-platelet binding, which were both reduced when an inhibitor of TPO was used. Thrombopoietin may enhance platelet activation in the early phases of UA, potentially participating in the pathogenesis of acute coronary syndromes.

    Clinical usefulness of once-daily administration of 20 to 60 mg of efonidipine hydrochloride and coronary hemodynamics during exercise 201 Tl myocardial scintigraphy were investigated in patients with angina pectoris. Out of 11 patients enrolled in this study, 9 patients were included in the evaluation of patients' impression, in improvement rating in subjective symptoms, in the analysis of the exercise test, in the improvement rating of images on 201 Tl myocardial scintigraphy, and in the global improvement rating, while 10 patients were included in the overall safety rating. Four patients in improvement rating in subjective symptoms, 2 in improving rating in the exercise test, and 5 in the global improvement rating were rated 'improved' or better. In the improvement rating on the exercise 201 Tl myocardial scintigraphy image, reduction of the image was observed in 5 patients, 3 out of which were evaluated as 'improved' or better. A distinctive reduction of ischemic regions was observed in 2 patients out of the 3. A significant decrease in the number of angina pectoris events and a decreasing tendency in consumption of fast-acting nitrates were observed in spite of the low number of the patients studied. An adverse effect was observed in 1 patient and abnormal laboratory values were observed in 2 patients which were improved promptly after withdrawal of the drug. It was in 7 patients evaluated as 'no problem', while in 4 patients it was evaluated as 'useful' or more. (author)

    This paper describes the psychometric properties of the French version of the APQLQ (Angina Pectoris Quality of Life Questionnaire), that is to say, scaling assumptions, reliability and validity. This disease-specific Swedish questionnaire provides a global score as well as four subscores measuring physical activities, somatic symptoms, emotional distress, and life satisfaction. The French version was produced according to the forward-backward translation methodology. In a cross-sectional study, 183 coronary patients filled out the APQLQ and the MOS (Medical Outcomes Study) SF-36; 170 sent it back; the rate of missing data was low (1.3%). The factorial structure and the high level of inter-scale correlations (> 0.60) suggested that the APQLQ measured one global concept rather than separate domains. The multitrait analysis identified one problematic item correlated strongly with all domains. The internal consistency was good (alpha Cronbach > 0.70). The correlations with the SF-36 scales were consistent with what was expected. The distribution of the scores of the APQLQ according to the clinical severity of Angina Pectoris (AP) was as hypothesized: the more severe the AP, the more impaired the Quality of Life. The score significantly discriminated between symptomatic (n = 110) and asymptomatic patients (n = 60) except for the emotional distress scale (p = 0.14). We recommend to analyze the French APQLQ as an index rather than as a profile. Its reliability, concurrent and clinical validity allowed its use in clinical trials.

    Objective: To observe changes of plasma neuropeptide Y(NPY) in patients with unstable angina pectoris (UaP), select patients with stable angina pectoris (SAP) and normal subjects as the controls, and recognize their significance. Methods: Immunoradiometric assay was used to measure the plasma NPY levels in 15 UAP patients, 20 SAP patients and 20 normal subjects: Results: It was found that the plasma NPY levels in patients with UAP, SAP and normal subjects were 202.12 +- 35.34, 164.45 +- 24.27 and 156.35 +- 21.84 pg/ml. The NPY levels in UAP patients were significantly higher than that in the others, but down to 159.66 +- 18.75 pg/ml after treatment for 2 weeks. There was a significant difference between pretreatment and post-treatment (P < 0.05). Conclusion: The plasma NPY levels of UAP patients increases significantly during fit. NPY takes part in the process of AP

    1987-01-01

    We studied by equilibrium radionuclide angiography 15 patients admitted to our coronary care unit because of PRINZMETAL's variant angina. Patients were examined mostly in the absence of symptoms. The incidence of ejection fraction abnormalities was low, while regional wall motion was always impaired at the site corresponding to ST-segment elevation at the time of the anginal attack. In 7 patients who underwent coronary angiography, we found an almost complete agreement between the site of atherosclerotic lesions and that of regional wall motion abnormalities. The patients were re-studied during intravenous perfusion of nitroglycerin: A detectable improvement of regional wall motion was found in 8 of them. We concluded that equilibrium radionuclide angiography appears to be a suitable tool for identifying reliably, in patients affected with PRINZMETAL's variant angina, the regional ventricular dysfunction remaining after the remission of symptoms in the presence of normalized ECG or signs of non-transmural ischemia. Equilibrium radionuclide angiography performed during nitroglycerin perfusion allowed us to evaluate in advance the importance of the vasospastic component and hence the efficacy of pharmacologic treatment.

    Full Text Available In a five year period 238 of 594 esophageal manometric studies performed in the authors’ laboratory were done on patients whose major reason for referral was noncardiac angina-like chest pain. Standard eophageal manometry was performed followed by an acid-antacid perfusion period (Bernstein test and then subcutaneous bethanechol (80 μg/kg to a maximum of 5 mg was adminstered. Baseline manometry was normal in 38% of patients and was diagnostic of ‘nutcracker’ esophagus, nonspecific esophageal motility disorder, diffuse esophageal spasm and isolated hypertensive lower esophageal sphincter in 24%, 19%, 16% and 3% of patients, respectively. Ninety-six of 238 patients (40% experienced reproduction of their presenting angina-like chest pain during acid perfusion. In 80% of these patients there were associated esophageal motor abnormal ilies induced by the acid perfusion. Thirty-six of 212 (17% experienced pain reproduction following the injection of bethanechol; however, 16 of these had already had their presenting chest pain reproduced during the acid perfusion study. In two-thirds of the patients with pain reproduction following bechanechol there was an associated bethanechol-induced esophageal motility disorder. Overall 49% of patients had their pain reproduced during provocative testing. The acid perfusion test reproduced the pain much more frequently than bethanechol simulation. This study reaffirms the value of esophageal manometry and provocative testing in this group of patients.

    To determine the effect of the introduction of casemix funding on resource utilisation and clinical outcomes in patients admitted to hospital with suspected unstable angina. A prospective cohort study with a 6-month follow-up. A suburban community hospital in Melbourne, Victoria. 336 consecutive patients admitted to the coronary care unit with suspected unstable angina before (156) and after (180) the introduction of casemix funding. Introduction of casemix funding in July 1993. Indices of resource utilisation: length of stay in hospital, length of stay in the coronary care unit, and total cost of investigations (pathology and radiology). Rates of serious cardiac events during hospital stay and after discharge. Readmissions within 28 days and 6 months of discharge. After the introduction of casemix funding there was a 1% increase in duration of hospital stay and a 5% increase in time spent in the coronary care unit, but neither of these increases was statistically significant. However, there was a significant reduction in total cost of investigations (39% decrease; 95% confidence interval, 14%-70%; P Casemix funding had no effect on short term clinical outcomes but resulted in significantly reduced investigation costs.

Five articles were included. The conclusions suggest that DHI plus conventional medicine treatment was effective for UA pectoris treatment, could alleviate symptoms of angina and ameliorate electrocardiograms. Flaws of the original studies and systematic reviews weaken the strength of evidence. Limitations of the methodology quality include performing an incomprehensive literature search, lacking detailed characteristics, ignoring clinical heterogeneity, and not assessing publication bias and other forms of bias. The flaws of reporting systematic reviews included the following: not providing a structured summary, no standardized search strategy. For the pooled findings, researchers took statistical heterogeneity into consideration, but clinical and methodology heterogeneity were ignored. Conclusion. DHI plus conventional medicine treatment generally appears to be effective for UA treatment. However, the evidence is not hard enough due to methodological flaws in original clinical trials and systematic reviews. Furthermore, rigorous designed randomized controlled trials are also needed. The methodology and reporting quality of systematic reviews should be improved.

    Background Complex angiography lesions and intracoronary thrombus have been identified in unstable angina.Braunwalds categorization has been accepted in the last years.Identifying severe clinical classes class III (angina at rest during the last 48 hours), class C (angina postinfarction) and class c (angina with maximum therapeutic). The main objective of this study was to determine independent associations of Braunwalds classes III, C and c: complex lesions, intracoronary thrombus, total occlusion and distal flux TIMI<3 of the responsible vessel. The secondary objectives were to analyze the angiographic features of the lesion and the responsible vessel. Aprospective study of 300 patients with diagnosed unstable angina, clustered according to Braunwalds clinis classification was done. The angiographic evaluation was performed identifying the responsible lesion and the presence of the complex lesion, intracoronary thrombus, total occlusion and distal flux TIMI<3 of the responsible vessel. A univariate analysis and a multivariate model of binary logistic regression were used. In the 300 patient population, 22 patients with normal coronaries(7.3%) were identified. The responsible lesion was identified in 243 out of the remaining 278 patients (87,4%). Class III was significantly associated with the complex lesion (OR=2.74, IC95%=1,27-5,9) and intracoronary thrombus (OR=2,82 IC95=1,2-6,6). Class C was significantly associated with intracoronary thrombus (OR=3.9),IC95%=1.53-10,0).Class III was and independent predictor for the presence of the complex lesion(OR=1.98, IC 95%=1,01-3,87) and intracoronary thrombus (OR=2,47 IC95%=1,14-5,37). Class C was and independent predictor for the complex lesion (OR=5,05,IC95%=2.25-11,3), infracoronary thrombus (OR=8,04, IC 95%=3,49-18,0), total occlusion (OR=6,49, IC95%=2,67-15,7) and distal flux TIMI<3(OR=3,96,IC 95%=1,87-8,4) There was no significant association between classes III, C and c and the responsible vessel, localization of

    Objective: To evaluate the diagnostic value of resting myocardial tomographic imaging with 123 I labelled BMIPP ( 123 I-BMIPP SPECT) for exercise-induced angina pectoris by comparison with stress myocardial tomographic imaging with 201 Tl( 201 Tl SPECT). Methods: 123 I-BMIPP SPECT and 201 Tl SPECT were performed in 32 patients with exercise-induced angina pectoris and 12 normal controls. Left ventricle was divided into nine segments and uptake of 201 TL and 123 I-BMIPP was evaluated by four classes score method (defect score, DS). Results: In the patients with angina pectoris, segments of 201 Tl distribution abnormality were more than that of 123 I-BMIPP. Concordant rate between DS of the 20 '1Tl SPECT for detecting coronary artery stenosis were 62%, 92% and 70%, respectively, and 201 Tl SPECT were 84%, 83% and 84%, respectively. Sensitivity of 123 I-BMIPP SPECT was significantly lower than that of 201 Tl SPECT (P 123 I-BMIPP SPECT will be. Conclusions: The results indicated that to a certain extent, resting 123 I-BMIPP SPECT may has practical clinical value for detection of coronary artery stenosis, and determination of stenotic degree in the patients with exercise-induced angina pectoris

    We studied regional myocardial perfusion by scintigraphic computer-assisted analysis of initial distribution, washout rates, and residual activity of 133 Xe injected into the left coronary artery of four patients with normal arteriograms and 14 patients with coronary stenosis. At rest, residual activity in poststenotic regions was always greater than in control regions, but initial washout rates were not slower. During angina, following xenon injections, the amount of indicator distributed to the poststenotic regions was markedly reduced; the increase of the initial washout rates was smaller than in control regions relative to rest, and residual activity was higher. Initial washout rates did not differ as much as from those of normal myocardium because in severe ischemia too little indicator is deposited initially in these regions to produce a change of any magnitude. Indeed, when angina was induced immediately after the xenon injection, poststenotic washout rates became much slower during angina than at rest, a finding that implicates functional factors in impairing poststenotic myocardial perfusion during angina

    Medically refractory angina remains a significant health concern despite major advances in revascularization techniques and emerging medical therapies. We aimed to determine the safety and efficacy of extracorporeal shockwave myocardial therapy (ESMT) in managing angina pectoris. A single-arm multicenter prospective study was designed aiming to determine the safety and efficacy of ESMT. Patients of functional Canadian Cardiovascular Society class II-IV, despite stable and optimal medical management, with documented myocardial segments with reversible ischemia and/or hibernation on the basis of echocardiography/single-photon emission computerized tomography (SPECT) were enrolled from 2010 to 2012. A total of 111 patients were enrolled, 33 from Indonesia, 21 from Malaysia, and 57 from Philippines. Patients underwent nine cycles of ESMT over 9 weeks. Patients were followed up for 3-6 months after ESMT treatment. During follow-up, patients were subjected to clinical evaluation, the Seattle Angina Questionnaire, assessment of nitrate intake, the 6-min walk test, echocardiography, and SPECT. The mean age of the population was 62.9±10.9 years. The summed difference score on pharmacologically induced stress SPECT improved from 9.53±17.87 at baseline to 7.77±11.83 at follow-up (P=0.0086).

    To evaluate the activity of natural killer cells through their inhibitory and activating receptors and quantity in peripheral blood mononuclear cells extracted from patients with acute myocardial infarction, stable angina pectoris and the controls. 100 patients with myocardial infarction, 100 with stable angina, and 20 healthy volunteers were recruited into the study. 20 randomly chosen people per group were examined for the whole human genome microarray analysis to detect the gene expressions of all 40 inhibitory and activating natural killer cell receptors. Flow cytometry analysis was applied to all 200 patients to measure the quantity of natural killer cells. In myocardial infarction group, the mRNA expressions of six inhibitory receptors KIR2DL2, KIR3DL3, CD94, NKG2A, KLRB1, KLRG1, and eight activating receptors KIR2DS3, KIR2DS5, NKp30, NTB-A, CRACC, CD2, CD7 and CD96 were significantly down-regulated (Pangina patients and the controls. There was no statistical difference in receptor expressions between angina patients and control group. The quantity of natural killer cells was significantly decreased in both infarction and angina patients compared with normal range (Pangina patients showed a quantitative loss and dysfunction of natural killer cells in myocardial infarction patients.

    Women with angina pectoris and abnormal stress test findings commonly have no epicardial coronary artery disease (CAD) at catheterization. The aim of the present study was to develop a risk score to predict obstructive CAD in such patients. Data were analyzed from 337 consecutive women with angina pectoris and abnormal stress test findings who underwent cardiac catheterization at our center from 2003 to 2007. Forward selection multivariate logistic regression analysis was used to identify the independent predictors of CAD, defined by ≥50% diameter stenosis in ≥1 epicardial coronary artery. The independent predictors included age ≥55 years (odds ratio 2.3, 95% confidence interval 1.3 to 4.0), body mass index stress imaging (odds ratio 2.8, 95% confidence interval 1.5 to 5.5), and exercise capacity statistic of 0.745 (95% confidence interval 0.70 to 0.79), and an optimized cutpoint of a score of ≤2 included 62% of the subjects and had a negative predictive value of 80%. In conclusion, a simple clinical risk score of 7 characteristics can help differentiate those more or less likely to have CAD among women with angina pectoris and abnormal stress test findings. This tool, if validated, could help to guide testing strategies in women with angina pectoris. Copyright © 2013 Elsevier Inc. All rights reserved.

    Inherited chromosomally integrated human herpesvirus-6 (iciHHV-6) results in the germ-line transmission of the HHV-6 genome. Every somatic cell of iciHHV-6+ individuals contains the HHV-6 genome integrated in the telomere of chromosomes. Whether having iciHHV-6 predisposes humans to diseases remains undefined. DNA from 19,597 participants between 40 and 69 years of age were analyzed by quantitative PCR (qPCR) for the presence of iciHHV-6. Telomere lengths were determined by qPCR. Medical records, hematological, biochemical, and anthropometric measurements and telomere lengths were compared between iciHHV-6+ and iciHHV-6- subjects. The prevalence of iciHHV-6 was 0.58%. Two-way ANOVA with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on continuous outcomes. Two-way logistic regression with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on disease prevalence. Of 50 diseases monitored, a single one, angina pectoris, is significantly elevated (3.3×) in iciHHV-6+ individuals relative to iciHHV-6- subjects (P = 0.017; 95% CI, 1.73-6.35). When adjusted for potential confounding factors (age, body mass index, percent body fat, and systolic blood pressure), the prevalence of angina remained three times greater in iciHHV-6+ subjects (P = 0.015; 95%CI, 1.23-7.15). Analyses of telomere lengths between iciHHV-6- without angina, iciHHV-6- with angina, and iciHHV-6+ with angina indicate that iciHHV-6+ with angina have shorter telomeres than age-matched iciHHV-6- subjects (P = 0.006). Our study represents, to our knowledge, the first large-scale analysis of disease association with iciHHV-6. Our results are consistent with iciHHV-6 representing a risk factor for the development of angina.

    Angina pectoris (Angina) is a medical condition related to myocardial ischemia. Although acupuncture has been widely accepted as a clinical approach for angina, there is no sufficient evidence of its effectiveness against this syndrome, and its mechanisms have not yet been well elucidated. We develop this protocol to confirm the clinical efficacy of electro-acupuncture on stable angina pectoris by needling on acupoint Neiguan (PC6). Furthermore, we employ high-throughput sequencing technology to investigate the gene expression profiling and determine involvement of histone modifications in the regulation of genes after electro-acupuncture treatment. A randomized, controlled, double-blinded (assessor and patients) trial will be carried out. Sixty participants will be randomly assigned to two acupuncture treatment groups and one control group in a 1:1:1 ratio. Participants in acupuncture groups will receive 12 sessions of electro-acupuncture treatment across 4 weeks, followed by a 12-week randomization period. The acupuncture groups are divided into Neiguan (PC6) on Pericardium Meridian of Hand-jueyin or a non-acupoint. The primary clinical measure of effect is the frequency of angina attacks between these groups for four weeks after randomization. RNAs are extracted from peripheral neutrophils collected from all participants on day 0, day 30, and week 16, and are processed to RNA-Seq. We then investigate profiles of histone modifications by ChIP-Seq, for H3 Lysine 4 (H3K4me) and acetylation of H3 Lysine 27 (H3K27ac), in the presence or absence of acupuncture treatment. This study determines the efficacy and mechanisms of electro-acupuncture on stable angina pectoris. We focus on effectiveness of acupuncture on alleviating symptoms of myocardial ischemia and the gene regulation and the chromatin remodeling marks, including H3K4me1, H3K4me2, and H3K27ac, which could be key factors for regulating gene expressions caused by electro-acupuncture treatment at Neiguan.

    2002-01-01

    Objective: To evaluate the efficacies of percutaneous coronary intervention (PCI) and drug treatment in patients with unstable angina (UAP). Methods: 248 patients with UAP were divided into two groups: conservative group of 123 patients who received antiplatelet, anticoagulant and antianginal therapies only and invasive group of 125 patients who underwent additional PCI 4.4 days after admission. The occurrence of death, AMI, recurrent angina, readmission were assessed during the first hospitalization year. Results: There was no difference in the incidence of composite endpoint of death or AMI between the two groups during the hospitalization (0.8 % vs 1.6 %, P > 0.05 ), but hospitalization duration was shorter in the invasive group than in the conservative group (10.3 ± 5.6 days vs 14.6 ± 10.7 days, P < 0.01 ). In duration of one year, the incidence of AMI (2.4% vs 8.9%, P<0.03), death (1.6% vs 6.5%, P<0.05), composite endpoint of death or AMI (4.0 % vs 13.0 % P < 0.02), recurrent angina pectoris (26.4 % vs 48.7, P <0.001), CABG (1.6% vs 10.5%, P<0.01) and readmission (24.8% vs 45.5%, P<0.01) were also lower in the invasive group than in the conservative group. Survival rate free of composite death or AMI for 1 year was higher in the invasive group than in the conservative group(96.0 % vs 86.9 %, P < 0.02). There was a definite benefit of the invasive treatment in reducing the risk of composite endpoint of death or AMI in patients with chest pain at rest, troponin T positive and three vessel diseases. Old age, three vessel diseases, LAD disease, lower LVEF, ST-segment depression, diabetes and hypertension were the independent factors associated with composite of death or AMI. Conclusions: In patients with UAP, PCI associated with routine antiplatelet, anticoagulant and antiischemic treatment significantly decreases the incidence of adverse cardiac events and improves the survival rate in one year. Such beneficial effects can be more obvious for high-risk patients

    In this double-blind randomized placebo-controlled crossover trial, we investigated whether oral sodium nitrate, when added to existing background medication, reduces exertional ischemia in patients with angina. Seventy patients with stable angina, positive electrocardiogram treadmill test, and either angiographic or functional test evidence of significant ischemic heart disease were randomized to receive oral treatment with either placebo or sodium nitrate (600 mg; 7 mmol) for 7 to 10 days, followed by a 2-week washout period before crossing over to the other treatment (n=34 placebo-nitrate, n=36 nitrate-placebo). At baseline and at the end of each treatment, patients underwent modified Bruce electrocardiogram treadmill test, modified Seattle Questionnaire, and subgroups were investigated with dobutamine stress, echocardiogram, and blood tests. The primary outcome was time to 1 mm ST depression on electrocardiogram treadmill test. Compared with placebo, inorganic nitrate treatment tended to increase the primary outcome exercise time to 1 mm ST segment depression (645.6 [603.1, 688.0] seconds versus 661.2 [6183, 704.0] seconds, P =0.10) and significantly increased total exercise time (744.4 [702.4, 786.4] seconds versus 760.9 [719.5, 802.2] seconds, P =0.04; mean [95% confidence interval]). Nitrate treatment robustly increased plasma nitrate (18.3 [15.2, 21.5] versus 297.6 [218.4, 376.8] μmol/L, P nitrate treatment). Other secondary outcomes were not significantly altered by the intervention. Patients on antacid medication appeared to benefit less from nitrate supplementation. Sodium nitrate treatment may confer a modest exercise capacity benefit in patients with chronic angina who are taking other background medication. URL: https://www.clinicaltrials.gov/.

    Objective: To explore the significance of platelet parameters, including mean platelet volume, platelet count and other haematological indices, in patients of acute coronary syndrome. Methods: In this one-year retrospective cross-sectional study in 2010, a total of 631 patients were enrolled at the Cardiovascular Research Institute, Tabriz University of Medical Sciences, Iran, and classified into three groups: myocardial infarction, unstable angina, and Control. Cardiovascular risk factors such as smoking, diabetes mellitus, hyperlipidaemia and hypertension status were compared. Blood samples were collected for the measurement of platelet count, mean platelet volume and other haematological indices, including prothrombin time, partial thromoplastin time, blood group and Rh, haematocrit, haemoglobin, and erythrocyte sedimentation rate. SPSS 18 was used for statistical analysis. Results: Of the total, there were 210 (33.3%; 163 men, 47 women) with myocardial infarction whose mean age was 62.7+-14.2 years; 211 (33.3%; 110 men, 101 women) had unstable angina with a mean age of 63.5+-13.1 years and 210 (33.3%; 117 men, 90 women) health controls with a mean age of 60.6+-12.8 years. The mean platelet volume values of patients in the first two groups were significantly higher than the control group (10.14 +-1.05 fL, 9.82 +- 0.93 fL and 9.34+-1.14 fL, respectively; p< 0.001). The platelet count was detected to be significantly lower in the patients than the controls (207.92+-58.40*109/L, 220.18+-65.81*109/L, 238+-56.10*109/L, respectively, p<0.001). While blood cell count was significantly higher in those with myocardial infarction compared to the unstable angina patients and control group (P<0.001). Differences in mean values of mean platelet volume between the two patient groups was not significant, but mean values of platelet count was statistically significant between these two groups (p<0.04). Conclusion: Mean platelet volume and platelet count may be considered

    Twelve patients with stable angina and 12 patients with unstable angina underwent rest iodine-123-β-methyl-iodophenyl-pentadecanoic acid (BMIPP), dipyridamole stress thallium scintigraphy and delayed thallium scintigraphy. In stable angina, sensitivity for detecting ischemic segments was higher in dipyridamole thallium (74%) than rest BMIPP (48%) images (p<0.05), but there was no significant difference between the 2 images in unstable angina. In unstable angina, the incidence of segments with higher defect scores on BMIPP images than on delayed thallium images and the opposite pattern was 27 and 5 (p<0.01). In stable angina, there was no difference. The mean defect score on BMIPP (6.3±5.6) was higher than that on delayed thallium scintigraphy (2.9±2.7) and it was almost the same as on the initial dipyridamole stress test (6.5±5.2). In conclusion, BMIPP scintigraphy is safer and may be as useful in detecting myocardial ischemia in patients with unstable angina as thallium scintigraphy. (author)

    The impact of preoperative stable angina pectoris on postoperative cardiovascular outcomes in patients with previous myocardial infarction (MI) who underwent major noncardiac surgery is not well studied. We studied patients with previous MI who underwent elective major noncardiac surgeries within the American College of Surgeons-National Surgical Quality Improvement Program (2005 to 2011). Primary outcome was occurrence of an adverse cardiac event (MI and/or cardiac arrest). Multivariable logistic regression models evaluated the impact of stable angina on outcomes. Of 1,568 patients (median age 70 years; 35% women) with previous MI who underwent major noncardiac surgery, 5.5% had postoperative MI and/or cardiac arrest. Patients with history of preoperative angina had significantly greater incidence of primary outcome compared to those without anginal symptoms (8.4% vs 5%, p = 0.035). In secondary outcomes, reintervention rates (22.5% vs 11%, p angina. In multivariable analyses, preoperative angina was a significant predictor for postoperative MI (odds ratio 2.49 [1.20 to 5.58]) and reintervention (odds ratio 2.40 [1.44 to 3.82]). In conclusion, our study indicates that preoperative angina is an independent predictor for adverse outcomes in patients with previous MI who underwent major noncardiac surgery, and cautions against overreliance on predictive tools, for example, the Revised Cardiac Risk Index, in these patients, which does not treat stable angina and previous MI as independent risk factors during risk prognostication.

    To understand the effect of hyperventilation (HV) stress in patients with spastic angina, left ventricular (LV) contraction was analyzed by quantitative phase analysis. The study was performed on 36 patients with spastic angina pectoris, including vasospastic angina pectoris (VspAP: 16 patients) and variant angina pectoris (VAP: 20 patients). First-pass radionuclide ventriculography (first-pass RNV) was performed at rest and after HV stress, and standard deviation of the LV phase distribution (SD) was analyzed. The SD was lower in patients with VspAP than in VAP(12.8{+-}1.4 degrees vs. 14.6{+-}2.2 degrees, p<0.005) at rest. After HV stress, the SD (HVSD) tended to increase in VspAP patients (62.5%), whereas the SD decreased in VAP patients (70%). Due to HV stress, the percentage change in SD (%SD) in VspAP patients was 8.9{+-}23.7% whereas that in VAP patients was -9.1{+-}17.3% (p<0.01). Moreover, phase histograms were divided into HVSD increase and HVSD decrease groups. The HVSD increase group had a decrease of HVEF, but the HVSD decrease group tended to have more decreased HVEF than the HVSD increase group. These results indicate that spastic angina pectoris patients show various responses to HV stress. The HVSD increase group might have additional myocardial ischemia due to regional coronary spasm. In contrast, in the HVSD decrease group severe LV dysfunction or diffuse wall motion abnormality might have been generated, and this caused a reduction in the SD value. Phase analysis would therefore add new information regarding electrocardiographically silent myocardial ischemia due to coronary spasm, and HV stress might increase sensitivity for the detection of abnormalities in quantitative phase analysis, especially in VspAP patients.

    There is a clear association between low serum testosterone and coronary artery disease (CAD) in men. Hypotestosteronaemia is associated with accelerated atherosclerosis and a quarter of men with CAD are biochemically hypogonadal. Amongst those with CAD, hypotestosteronaemia is associated with increased mortality. Testosterone vasodilates coronary arteries, and exogenous testosterone reduces ischaemia. Whether hypotestosteronaemia is a cause or a consequence of CAD remains unanswered. The aim of this prospective observational study was to investigate whether coronary revascularization affected androgen status in men with stable angina pectoris. Twenty five men (mean age 62.7, SD 9.18) with angiographically significant CAD and symptomatic angina underwent full coronary revascularization by percutaneous coronary intervention. Androgen status and symptoms of angina, stress, depression and sexual function were assessed before, and at one and 6 months after the coronary revascularization. All patients underwent complete revascularization which was associated with a significant reduction in angina symptoms and ischaemia. No significant difference was seen in total testosterone (11.33 nmol/L baseline; 12.56, 1 month post; 13.04 at 6 months; p = 0.08). A significant and sustained rise in sex hormone-binding globulin was seen (33.99 nm/L baseline; 36.11 nm/L 1 month post PCI; 37.94 nm/L at 6 months; p = 0.03) Overall, there was no significant alteration in any other marker of androgen status including free testosterone or bioavailable testosterone. There was no change in symptoms of anxiety, depression or sexual function. Coronary revascularization has no sustained effect on androgen status. This supports the hypothesis that hypotestosteronaemia is not a consequence of angina pectoris or myocardial ischaemia. © 2016 American Society of Andrology and European Academy of Andrology.

The HVSD increase group had a decrease of HVEF, but the HVSD decrease group tended to have more decreased HVEF than the HVSD increase group. These results indicate that spastic angina pectoris patients show various responses to HV stress. The HVSD increase group might have additional myocardial ischemia due to regional coronary spasm. In contrast, in the HVSD decrease group severe LV dysfunction or diffuse wall motion abnormality might have been generated, and this caused a reduction in the SD value. Phase analysis would therefore add new information regarding electrocardiographically silent myocardial ischemia due to coronary spasm, and HV stress might increase sensitivity for the detection of abnormalities in quantitative phase analysis, especially in VspAP patients.

    Full Text Available neck mass is a common condition in primary care. the most common affected area is the cervical lymph node. the neck region is also prone infection as structurally the nodes and spaces are in close contact with the upper respiratory tract and the alimentary tract. oral cavity is one of the most common route for harbouring infection. Poor oral hygeine and periapical dental problems are the main causes. thus, it is important to perform a complete oral cavity examination even when trismus is present. Besides dental caries, floor of the mouth should be inspected for oedema that may impose threat to the upper airway. We report a case of Ludwig’s angina originating from a periapical lesion of the lower molar stressing the importance of oral examination in patient with neck mass.

    Full Text Available Bullosa Haemorrhagica (ABH is a rare oral blood blisters disorder. This recurrent disorder is restricted to oral mucosa and its difference with other oral vesiculobullos disorders is that blood vesicles are formed after minor trauma and in the absence of any blood dyscrasia, vesiculobullos disease and systemic disorder. This blood blisters are without pain, with color of dark red and full of bloods that rapidly enlarge and rapidly burst. The incidence of Angina Bullosa Haemorrhagica is unknown. Diagnosis of this disorder and differentiation from vesiculobullos disease like pemphigus and pemphiguid is important for patient's health. In this report we introduce a 55 years old woman with a 4­years history of oral blood blisters. These vesicles were in lateral border and ventral surface of tongue and on the ferenum. In medical history the patient had churg strauss syndrome and using inhalation corticosteroid for control of asthmatic attacks (An etiologic factor for appearing or aggravation of the disease.

    Numerous controlled studies have shown that nitrates, beta blockers, and calcium antagonists are effective in the treatment of stable angina pectoris. The pharmacokinetics, pharmacodynamics, and hemodynamic effects of these agents are different, and thus combination therapy offers additive improvement and also counterbalancing of the undesirable side effects of each drug. The choice of therapy depends on the severity of symptoms, associated diseases, compliance, side effects, and status of left ventricular function. The main mechanism of improvement is a decrease in myocardial oxygen consumption, though an increase in coronary blood flow is another potential reason for the use of calcium blockers. This review considers the properties of these drugs, their mechanism of action, and the results of randomized studies.

    Objective: To investigate the short-term prognostic value of thrombus precursor protein (TpP) in patients with unstable angina (UA). Methods: One hundred and ten cases of UA were selected. The TpP was measured by enzyme linked immunosorbent assay (ELISA). The cardiovascular events were observed in 6 months. Results: In the 100 cases of UA, the cardiovascular events were observed in 17 cases. There was an significant difference in three levels of TpP (P<0.05). The risk level was increasing as the increasing of the plasma level of TpP. Conclusion: The level of TpP has certain reference value and plays a role in forecasting of the short-term prognosis of the patients with UA. When the plasma level of TpP increases there is also an increase in OR. (authors)

    Full Text Available OBJETIVO Analisar o padrão de atividade física de gestantes de baixo risco e os fatores associados. MÉTODOS Estudo transversal com 256 gestantes adultas no segundo trimestre gestacional, sorteadas dentre as assistidas pelas unidades de atenção primária à saúde do município de Botucatu, SP, em 2010. As atividades físicas foram investigadas por meio do “pregnancy physical activity questionnaire”, verificando-se tempo e intensidade de atividades ocupacionais, de deslocamento, domésticas e de lazer, expressos em equivalentes metabólicos dia. As gestantes foram classificadas segundo nível de atividade e em relação a atingir 150 min/semana de atividades físicas de lazer, variáveis dependentes do estudo. A associação entre essas variáveis e as socioeconômicas, características maternas, fatores comportamentais e modelo de atenção da unidade de saúde foi avaliada mediante modelos de regressão de Poisson com variância robusta, adotando-se modelo hierárquico. RESULTADOS A maior parte das gestantes era insuficientemente ativa (77,7%, 12,5% moderadamente ativa e 9,8% vigorosamente ativa. Os maiores gastos diários de energia foram com atividades domésticas, seguidas pelas atividades de locomoção; 10,2% atingiram a recomendação de 150 min semanais de atividades físicas de lazer. Trabalho fora de casa reduziu a chance de atingir essa recomendação (RP = 0,39, IC95% 0,16;0,93. Ter tido pelo menos um parto anterior (RP = 0,87, IC95% 0,77;0,99 e excesso ponderal pré-gestacional (RP = 0,85, IC95% 0,731;0,99 reduziram a chance de ser insuficientemente ativa, enquanto consumir menos alimentos saudáveis teve aumento discreto (RP = 1,18, IC95% 1,02;1,36. CONCLUSÕES Gestantes assistidas na atenção primária à saúde são insuficientemente ativas. Ter tido pelo menos um parto e apresentar sobrepeso pré-gestacional foram identificados como fatores protetores contra tal situação, enquanto consumo menos frequente de alimentos

Between graphs and bits  Abstract This paper delves into the intersections of analogue and digital cultures, at the points at which low and high technology converge. While acknowledging the materiality of these two spheres, I aim to produce an enquiry into objects, drawings and documentation practices that can contribute to developing new research methods. Among graphs and bits, I will dissect one object: the #relatograma, in order to analyze its ecology and propose a critical reflection on its digital condition and its ability to produce aggregated landscapes, or what I define as #coreograma. I will thereby explore its ability to be share information and produce knowledge. Keywords: Material culture; research methods; digital objects; drawing; #relatograma.

    To evaluate the cost-effectiveness of trimetazidine (TMZ) as add-on therapy to standard-of-care (SoC) compared to SoC alone in patients with chronic stable angina who did not respond adequately to first line therapy with b-blockers, nitrates or calcium channel antagonists in Greece. A Markov model with 3-month cycles and 1-year time horizon was developed to assess the comparators. The analysis was conducted from a third-party payer perspective. The clinical inputs and utility values were extracted from the published literature. Resource consumption data were obtained from local experts, using a questionnaire developed for the purpose of the study and were combined with unit cost data (in €2016) obtained from official sources. Cost effectiveness was assessed by calculating the incremental cost effectiveness ratio (ICER). Probabilistic sensitivity analysis (PSA) was performed to account for uncertainty and variation in the input parameters of the model. The analysis showed that the cost of TMZ plus SoC was €1755.57 versus €1751.76 of SoC alone. In terms of health outcomes, TMZ plus SoC was associated with 0.6650 QALYs versus 0.6562 QALYs for SoC alone. The incremental analysis resulted in an ICER of €430.67 per QALY gained. PSA revealed that the probability of TMZ plus SoC being cost-effective over SoC was 89 %, at a threshold of €34,000 per QALY gained. The results indicate that TMZ as add -on treatment may be a highly cost-effective option for the symptomatic treatment of patients with chronic stable angina in Greece relative to SoC alone.

    BACKGROUND: Chronic stable angina (CSA) is a major debilitating health problem in Canada. A paucity of relevant cardiovascular data sets has precluded a detailed examination of the impact of interventions on CSA-related costs and its broader economic burden. OBJECTIVES: As part of a larger clinical trial, the authors sought to determine the short-term impact of a standardized self-management training program on CSA-related costs. A secondary objective was to estimate the total annualized cost of CSA per patient from a societal perspective. METHODS: Pre- and three-month post-test cost data were collected on 117 participants using the Ambulatory Home Care Record. Mean annualized direct, indirect and system-related CSA costs (2003 to 2005) were estimated; total per-patient CSA costs from a societal perspective were calculated as the sum of these costs. RESULTS: The mean (± SD) age of participants was 68±11 years; 80% were male. The program did not impact costs in the short-term. Direct annual out-of-pocket costs, including money paid for health care, travel to appointments, medication, equipment and home support totaled $3,267. Indirect costs, reflecting the value of all unpaid time spent by those engaged in angina-related care, were $12,963. System costs, including costs paid by public and private insurers, were $2,979. Total estimated annual CSA costs from a societal perspective were $19,209 per patient. CONCLUSIONS: These data suggest that CSA imposes a major economic burden, comparable with other prevalent conditions such as chronic noncancer pain. Advancements in self-management training research are needed to help reduce the economic burden of CSA in Canada. PMID:18841254
