    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.

OBJETIVO: Este estudio tuvo dos objetivos. En primer lugar, comparar los niveles séricos de proteína C reactiva (PCR y interleuquina-6 (IL-6 en pacientes diabéticos y no-diabéticos con angina inestable (AI para determinar si la diferencia en la actividad inflamatoria justifica el empeoramiento pronóstico en los pacientes diabéticos. En segundo, evaluar la correlación entre los marcadores inflamatorios y el perfil metabólico en pacientes diabéticos y entre la respuesta inflamatoria y los desenlaces hospitalarios, como muerte, infarto agudo de miocardio, insuficiencia cardiaca congestiva y tiempo de hospitalización. MÉTODOS: Estudio de cohorte prospectiva de 90 pacientes consecutivos, ingresados a la Unidad de Dolor Torácico con angina inestable. Se dividieron a los pacientes en dos grupos: diabéticos y no-diabéticos. Los niveles séricos de PCR e IL-6, el perfil metabólico y el conteo de leucocitos se obtuvieron al ingreso al hospital. RESULTADOS: De todos los pacientes analizados, 42 (47% eran diabéticos (edad 62 ± 9 y 48 (53% no eran diabéticos (edad 63 ± 12. No se encontraron diferencias entre la mediana de la PCR (1,78 vs. 2,23 mg/l, p = 0,74 y de la IL-6 (0 vs. 0 pg/ml, p = 0,31 entre los dos grupos.

    To investigate the probable ictal origin of unexplained episodic chest pain and if possible to lateralize and localize the epileptic focus. A 14 year old boy presented with episodic short lasting localized chest pain. His cardiac and other systemic work-up were normal. MRI brain did not reveal any structural pathology. Video telemetry was done for characterization of the paroxysms. Interictal record showed left fronto-central epileptiform discharges. A left hemispheric, predominantly centroparietal ictal rhythm was identified. The possible localizations of this unusual semiology are somatosensory areas I and II, supplementary sensorimotor area, posterior insula and cingulate cortex. Patient responded remarkably to antiseizure drugs. Pain is a rare manifestation of epilepsy observed in less than 1% of patients. When present, it is usually accompanied by other focal features. This rare occurrence of epileptic seizures masquerading as angina is a novel observation.

    2004-09-01

    Full Text Available Las mutaciones inestables constituyen un tipo de alteración genética descubierta en la década de los noventa. En condiciones normales, regiones específicas de los genes están constituidas por repeticiones de una secuencia corta que puede ser de tres, cuatro, cinco o más nucleótidos; por ejemplo CAG, CGG, ATTCT, etc. Este nuevo tipo de mutación consiste en un aumento en la cantidad de éstas repeticiones, lo que causa una alteración en la expresión de dichos genes. Son inestables porque se ha observado que el tamaño de la secuencia repetida varía cuando las células se dividen por mitosis o meiosis, lo cual tiene implicaciones sobre la herencia y por consiguiente sobre el consejo genético que debe brindarse a los afectados. Estas mutaciones se han encontrado en genes importantes para la función neurológica normal del ser humano, donde pueden alterar el transporte de los ARN desde el núcleo al citoplasma, provocar la inactivación del gen o producir una proteína con funciones nuevas. La mayoría de las enfermedades causadas por estas mutaciones afectan el sistema nervioso, son degenerativas y presentan el fenómeno de anticipación genética, es decir que los afectados dentro de una familia se enfermarán más jóvenes y en forma más severa con el paso de las generaciones. La cantidad de repeticiones de la secuencia repetida presenta una correlación negativa con la edad de manifestación, así como una correlación positiva con la severidad de la enfermedad. En este momento existen veinte padecimientos identificados que son causados exclusivamente por este tipo de mutación. Este trabajo es una breve revisión actualizada del tema.Unstable mutations, new challenges for genetic counseling of inherited disorders. Unstable mutations or amplification of DNA tandem repeats sequences constitute a new kind of genetic alteration discovered in the 90´s that cause hereditary diseases.

    While the incidence of Ludwig angina is decreasing, this is an important disease process because failure to control the airway can have catastrophic consequences. Accurate diagnosis, airway control, antibiotic therapy, and, occasionally, surgical management are essential for patient safety. Ludwig angina is caused by a rapidly expanding cellulitis of the floor of the mouth and is characterized by hardened induration of the floor and suprahyoid region bilaterally with an elevation of the tongue potentially obstructing the airway. In the preantibiotic era, Ludwig angina was frequently fatal; however, antibiotics and aggressive surgical treatment have significantly lowered mortality.

    2007-10-01

    Full Text Available Resumen: En los últimos años se han desarrollado diversos métodos para controlar sistemas mecánicos subactuados. De hecho, dichos métodos no lineales han conseguido resolver problemas muy interesantes desde el punto de vista de control. Sin embargo, para obtener una solución con estos métodos, normalmente es necesario resolver un sistema de ecuaciones diferenciales en derivadas parciales, lo cual no siempre es posible. En este artículo, se presenta una metodología constructiva para diseñar un controlador para una clase de sistemas mecánicos inestables en bucle abierto y con grado de subactuación uno. Para el diseño se emplean principalmente las técnicas de linealización por realimentación y Lyapunov. La metodología consiste en proponer una salida ficticia que se pueda rediseñar de forma constructiva para resolver el problema planteado, dando lugar a una ley de control explícita, que permite tener en cuenta la fricción incluso en las coordenadas no actuadas.

    Patterson, H C; Kelly, J H; Strome, M

    1982-04-01

    Despite a reduction in preantibiotic mortality rates that exceeded 50%, Ludwig's angina remains a potentially lethal entity primarily because of rapidly progressive airway obstruction. Since the reports of several large series in the 1940's, there have been put sporadic case reports because of widespread use of antibiotics in orodental infection, improved dental care, as well as adherence to strict diagnostic criteria. Since this entity is now uncommon, unnecessary delay in diagnosis and management may occur and may result in serious complications. This presentation will consist of an historical review, discussion of pathogenesis followed by clinical presentation, bacteriology and treatment, as well as a detailed analysis of our most recent 20 cases. There were no complications and no deaths. The infection resolved with medical therapy in 11 patients, while 9 patients required surgical procedures. Penicillin, clindamycin or chloramphenicol were started initially in all cases. Four of these 9 patients developed a localized abscess, while on antibiotics, which required drainage. Tracheotomy or intubation was necessary in 7 patients. Early and aggressive use of appropriate antibiotics and protection of the airway are the mainstays of a successful treatment regimen. Judicious surgical intervention is indicated in those patients who develop localized abscesses while on antibiotics or are unresponsive to medical management.

    A 37-year-old 91 kg man presented with features of Ludwig's angina. Anaesthesia for incision and drainage of his submandibular abscess was undertaken by two specialist anaesthetists with an otorhinolaryngological surgeon prepared for immediate tracheostomy. After preoxygenation, gas induction with sevoflurane in oxygen was followed by a gush of pus into the oral cavity and laryngospam causing acute upper airway obstruction. This resolved with 25 mg of suxamethonium and an endotracheal tube was passed into the trachea with difficulty. Options for management of the difficult airway in Ludwig's angina are discussed.

    Ludwig's angina is caused by a rapidly expanding cellulitis of the floor of the mouth and is characterized by a brawny induration of the floor and suprahyoid region (bilaterally), with an elevation of the tongue potentially obstructing the airway. In the pre-antibiotic era, Ludwig's angina was frequently fatal; however, antibiotics and aggressive surgical intervention have significantly reduced mortality. We reviewed nine patients with Ludwig's angina between July 1996 and June 2002, all of whom presented with fever, neck swelling, bilateral submandibular swelling and elevation of the tongue. In eight patients (89%) a dental infection appeared to be the underlying cause. High-dosage intravenous antibiotics directed towards the suspected causative microorganisms were given to all of the patients: two were treated successfully with conservative medical management, while seven underwent surgical drainage (a tracheotomy was necessary in one patient). Routine aerobic cultures were done on samples of drained material and the predominant microorganisms were Streptococcus species in two patients; there were none in the other five. Two patients had post-operative complications, but all recovered.

    Modern dental care and use of antibiotics for oral infections have made Ludwig's angina rare. To avoid acute airway obstruction, emergency physicians must be able to rapidly recognize and treat this condition. A typical case of Ludwig's angina is presented, followed by a review of clinical findings and therapeutic modalities. Emphasis is made on airway management, antibiotics, and surgical drainage.

    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

Para el análisis de datos se siguieron las reglas del método etnográfico y procedimientos de la teoría fundamentada. La interacción de los indígenas con la sociedad antioqueña muestra superposición de sistemas de cosmovisión con la religión católica y pérdida de sistemas propios de subsistencia para adoptar sistemas ajenos sin ninguna garantía de mejoría de las condiciones de vida y, en ocasiones empeoran las condiciones previas. Las condiciones externas adversas de inseguridad, pobreza, marginalidad y exclusión no permiten que las acciones y prácticas de sobrevivencia tengan eficacia, lo cual da como resultado un equilibrio inestable de pervivencia como sociedad culturalmente diferenciada.This paper presents the category unstable balance that emerged as part of a larger study on survival on ethnic minorities in weak living conditions. The study is ethnographic and uncovers the Chamibida practices to achieve cultural and social survival . It took place in an indigenous reserve in Antioquia during 150 days of field work. To analyse data procedures of the ethnographic method and grounded theory were followed. The interaction of the indigenous shows an overlap of traditional belief system with catholic religion and a loss of their own systems of survival in order to adopt other systems with no guarantee to improve living conditions and sometimes they worsen previous living conditions.

    A case of Ludwig's angina which developed after mandibular fractures in a 14-year-old male patient is reported. We emphasise the serious nature of this condition and the aggressive treatment it requires. It is important to recognise cases of Ludwig's angina at an early stage, as well as cases which are at risk of developing into true Ludwig's angina if treatment is delayed. Management should be aimed at maintaining an open airway by nasotracheal intubation or cricothyroidotomy, together with treatment of the infection by removal of the source, drainage of pus and parenteral antibiotic therapy. In addition, investigation and management of contributing medical conditions and timely specialist consultation are essential.

    Ludwig's angina (LA) is a dangerous surgical condition that can cause severe airway compromise and death. There is controversy regarding the best way to manage the airway of patients with LA. Options range from conservative management involving close observation and i.v. antibiotics to airway intervention, including tracheostomy and endotracheal intubation using fibre-optic nasoendoscopy. We present evidence supporting a role for conservative airway management in a select subset of patients. This paper reviews 9 years' experience of treating patients with LA at Liverpool Hospital. Twenty-one out of 29 (72%) of our patients were treated conservatively following initial clinical assessment. One of these patients subsequently deteriorated requiring emergency intubation. Of those treated non-conservatively at initial presentation, seven patients were able to be intubated using fibre-optic nasoendoscopy and one patient required tracheostomy under local anaesthesia. A general discussion of issues related to the management of LA is presented. Based on our experience we conclude that there is a subset of patients with LA who can be managed safely with conservative management.

    Early awareness, recognition, and treatment of angina can help prevent or delay an acute myocardial infarction and potentially delay death. A patient's educational level may affect a physician's diagnosis of angina and/or a patient's symptom recognition. The objective of this study was to determine whether low education is a risk factor for undiagnosed angina. This was a cross-sectional observational study based on data from the National Health and Nutrition Examination Survey 2001 to 2008, providing a nationally representative sample of adults ≥40 years of age with angina based on physician diagnosis, presence of angina symptoms based on the Rose Questionnaire, or both. Educational attainment (high school or less vs more than high school) was the independent variable of interest. Undiagnosed angina (angina symptoms in the absence of angina diagnosis) was the dependent variable. We used logistic regression to control for age, sex, race/ethnicity, income, and health care visit during the past year. Low education was associated with undiagnosed angina (odds ratio: 1.43; 95% confidence interval: 1.01-2.03). Other undiagnosed angina predictors included being female, being black, and having no health care visit during the past year. Low education is associated with undiagnosed angina. These results underscore the need for providers to ask about angina symptoms and confirm patients' understanding of their angina diagnosis among those with low education.

    As many as 1 in 3 of cases of Ludwig's angina occur in children and adolescents, and pediatricians are therefore ideally situated to detect these individuals at an early stage of their potentially life-threatening disease. The early identification and referral of children afflicted with Ludwig's angina to tertiary care centers allows for the rapid initiation of medical therapy and the consultation of those emergency services critical to providing such patients with optimal diagnostic and therapeutic interventions. This review provides an overview of the anatomical and pathophysiological considerations in Ludwig's angina and describes practical management principles to assist pediatricians in the diagnosis and treatment of this disease. Included in this review is an evidence-based algorithm for airway management.

    Inhalation of small amounts of carbon monoxide diminishes the pain threshold in patients with stable angina pectoris. The aim of this study was to identify and describe patients who had been exposed unknowingly to toxic inhalations of this gas and subsequently presented to hospital with a clinical picture of unstable angina. Blood carboxyhaemoglobin levels of 104 patients referred with unstable angina to a coronary care unit were determined on admission. The likely source of carbon monoxide was identified in all patients. Three patients had definite carbon monoxide intoxication. Another five patients had evidence of minor exposure. When the three cases with carbon monoxide poisoning were excluded, the mean carboxyhaemoglobin level was 2.5% (+/- 1.3) for smokers (n = 30) and 0.6% (+/- 0.5) for non-smokers (n = 71). Use of fossil fuel combustion in an enclosed environment was responsible for the three most serious intoxications and one of the minor cases. We suggest that a number of patients admitted for coronary care with unstable angina may have significant carbon monoxide poisoning. This intoxication is often overlooked by attending physicians with the result that high concentration oxygen therapy is not administered, when it is in fact a necessary part of treatment.

    Refractory angina (RFA) is an unfavourable condition that is characterized with persistent angina due to reversible myocardial ischemia in patients with coronary artery disease that remains uncontrollable despite an optimal combination of pharmacological agents and revascularization. Despite significant advances in revascularization techniques and agents used in pharmacological therapy, there is still a significant population suffering from RFA and the global prevalence is even increasing. Anti- anginal treatment and secondary risk-factor modification are the traditional approaches for this group of patients. Furthermore, now there is still a large number of alternative treatment options. In order to review traditional and alternative treatment strategies in patients with RFA, we searched Pubmed for articles in English using the search terms "pharmacological therapy, refractory angina", "alternative therapy, refractory angina" between inception to June 2016. We also went through separately for each alternative treatment modality on Pubmed. To identify further articles, we handsearched related citations in review articles and commentaries. We also included data from the European Society of Cardiology (2013), and the Canadian Society of Cardiology/ Canadian Pain Society (2012) guidelines. Data show that besides traditional pharmacological agents, such as nitrates, beta- blockers or calcium channel blockers, novel antiischemic drugs and if symptoms persist, several non- invasive and/ or invasive alternative strategies may be considered. Impact of some pharmacological agents, such as rho- kinase inhibitors, and novel alternative treatment modalities, such as coronary sinus reducers, stem cell therapy, gene and protein therapy, on outcomes are still under investigation.

    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

    2014-01-01

    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

    2007-12-01

    Ludwig angina remains a potentially lethal disease, rapidly spreading bilateral cellulitis of the submental, sublingual, and submandibular spaces, which bears the threat for rapid airway obstruction. Since the introduction of antibiotics in 1940s, the mortality was reduced significantly. This resulted in the rare occurrence of the disease, leaving many physicians with limited experience of Ludwig angina. Although the occurrence of Ludwig angina in adults is rare, its presence in the pediatric edentulous population is even more uncommon. Because the unfamiliarity with this disease is now increasing, unnecessary delaying diagnosis or inadequate management may occur and may result in serious complications. This presentation will consist of a historical review, discussion of pathophysiology, followed by clinical presentation, etiology, bacteriology, and management. With early diagnosis, airway observation and management, aggressive intravenous antibiotic therapy, and judicious surgical intervention, the disease should resolve without complications. In addition, the source of infection should be determined and eliminated if possible. A thoughtful, individualized management strategy seems to be the most reasonable approach to the disease.

    Patients with deep neck infections present challenging airways for an anesthesiologist. Patients with Ludwig's angina may die as a result of the inability to effectively manage the airway. Here we discuss the anesthetic management with fiberoptic intubation of a 45-year-old man with Ludwig's angina scheduled for emergency drainage. Awake fiberoptic intubation under topical anesthesia may be the ideal method to secure the airway in advanced cases of Ludwig's angina. When fiberoptic bronchoscopy is not feasible, not available or has failed, an awake tracheostomy may be the preferred option.

    Full Text Available Resumen: El término síndrome X o angina microvascular se emplea habitualmente para definir a un grupo de pacientes que presentan dolor torácico característico, depresión del segmento ST durante el esfuerzo y arterias coronarias angiográficamente normales. Muchos datos apuntan a un posible origen isquémico de los síntomas. Es más frecuente en mujeres y en casi el 50 % de ellas, el dolor anginoso se atribuye específicamente a cambios en la microvasculatura coronaria. Debido a que el pronóstico no es tan benigno como se creía hace años, en pacientes con angina y coronarias epicárdicas normales, se impone una evaluación clínica (incluyendo un cuidadoso análisis de los factores de riesgo e imagenológica, con el propósito de detectar isquemia funcionalmente significativa. La enfermedad coronaria microvascular es, por tanto, una enfermedad que requiere atención por parte del médico de asistencia. En este artículo se presenta una paciente con este diagnóstico, y se muestran las imágenes electrocardiográficas, ecocardiográfica, ergométricas y angiográficas. / Abstract: The term cardiac syndrome X or microvascular angina is commonly used to describe a group of patients who show a typical chest pain, ST segment depression during exercise and angiographically normal coronary arteries. Many data suggest the symptoms may have an ischemic origin. It is more common in women, and, in almost 50% of them, anginal pain is specifically attributed to changes in the coronary microvasculature. The prognosis is not as benign as it was believed for years; therefore, in patients with angina and a normal epicardial coronary, a clinical and imaging assessment is necessary (including a careful analysis of risk factors in order to detect a functionally significant ischemia. Therefore, coronary microvascular disease is a condition that requires attention by the attending physician. A patient with this diagnosis is reported in this article, and

    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.

    Ludwig's angina is an uncommon but potentially fatal condition which presents as a hard swelling of the floor of the mouth. It spreads rapidly as a gangrenous process that may cause death through local airway obstruction. Ludwig's angina carried a 54% mortality rate in the preantibiotic era which has now been reduced to approximately 4%. Diagnosis is based on history and clinical observation. Currently described treatment involves protecting the airway and managing the infection with antibiotics and surgical drainage when indicated.

    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

    Bevacizumab, an inhibitor of vascular endothelial growth factor (VEGF)-A, is currently used to treat patients with ovarian or colon cancer. While several cardiovascular toxicities related to bevacizumab-containing regimens have been reported, the effect of bevacizumab on the coronary microcirculation has not been fully elucidated. Here we report a case of 54-year-old female patient who developed microvascular angina after a series of bevacizumab-containing chemotherapeutic regimen. The discontinuation of bevacizumab and nicorandil administration was effective in alleviating her chest discomfort and the ischemic changes on her ECG. This highlights the possibility that coronary microvascular angina can be induced in patients treated with bevacizumab-containing chemotherapy. It should also be noted that nicorandil can be effective in managing microvascular angina.

    This case is of a 76-year-old man who presented to the emergency department with a 24-h history of a progressive tense, tender midline neck swelling. A computed tomography scan revealed Ludwig's angina and the patient went on to develop respiratory compromise and was admitted to the intensive care unit. The patient's clinical course later became complicated by abscess formation requiring drainage under general anaesthetic. He was eventually discharged home some 9 days after his initial presentation. The emergency medicine management issues surrounding Ludwig's angina are discussed briefly. This case highlights the dynamic airway changes seen in this uncommon condition. Whereas Ludwig's angina has previously been associated in the emergency medicine literature with a younger age group and in patients with a history of dental infection or treatment, this case highlights the fact that it may occur despite these two common associations.

    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.

    Description of the chest pain of angina pectoris by patients is commonly used in the diagnosis, evaluation and monitoring of ischaemic heart disease. Whilst certain descriptive terms have been identified as describing angina and not other causes of chest pain, these terms have not been systematically evaluated among local Malaysian patients. Reliance on a translation of the description used by Western patients may not be totally correct in the local context. Seventy-one Malay patients with documented ischaemic heart disease were asked, by questionnaire and by interview, to identify the descriptive terms they used for their angina pectoris. Common terms used by these patients were sempit (constrictive) [56.3%], mencuck (pricking) [54.9%], berat (heavy) [53.5%], panas (burning) [50.7%], menekan (pressing) [46.4%], and pedih (smarting) [43.7%]. Other less common descriptions used were tajam (sharp), mencengkam (strangulating), hempap (compressive), ngilu, hiris (knife-like), lengoh (aching). Two-thirds of the patients used more than three terms to describe their angina pectoris. Direct translation of the description of angina may not only be inaccurate but could also be misleading. It is suggested that the actual words used by the patients in Bahasa Malaysia be recorded in the patient's notes rather than a translation of these. More studies are required to determine whether the terms used by the patients in this study are related to local dialect (in this case Terengganu) or are actually common in Malaysia. Further, similar studies among Chinese and Indian patients are also required.

  12. Emerging clinical role of ranolazine in the management of angina

    Full Text Available David S Vadnais, Nanette K WengerDivision of Cardiology, Emory University School of Medicine, Atlanta, Georgia, USAAbstract: Chronic stable angina is an exceedingly prevalent condition with tremendous clinical, social, and financial implications. Traditional medical therapy for angina consists of beta-blockers, calcium channel blockers, and nitrates. These agents decrease myocardial oxygen demand and ischemia by reducing heart rate, lowering blood pressure, and/or optimizing ventricular loading characteristics. Unique in its mechanism of action, ranolazine is the first new antianginal agent approved for use in the US for chronic angina in over 25 years. By inhibiting the late inward sodium current (INa, ranolazine prevents pathologic intracellular calcium accumulation that leads to ischemia, myocardial dysfunction, and electrical instability. Ranolazine has been proven in multiple clinical trials to reduce the symptoms of angina safely and effectively and to improve exercise tolerance in patients with symptomatic coronary heart disease. These benefits occur without reduction in heart rate and blood pressure or increased mortality. Although ranolazine prolongs the QTc, experimental data indicate that ranolazine may actually be antiarrhythmic. In a large acute coronary syndrome clinical trial, ranolazine reduced the incidence of supraventricular tachycardia, ventricular tachycardia, new-onset atrial fibrillation, and bradycardic events. Additional benefits of ranolazine under investigation include reductions in glycosylated hemoglobin levels and improved left ventricular function. Ranolazine is a proven antianginal medication in patients with symptomatic coronary heart disease, and should be considered as an initial antianginal agent for those with hypotension or bradycardia.Keywords: chronic angina, myocardial ischemia, ranolazine, pharmacotherapy, antianginal, sodium current

    A 71-year-old woman with cellulitis of the floor of the mouth, referred to as "Ludwig's angina", underwent emergency tracheostomy under general anesthesia, for the control of airway narrowing caused by sublingual and submandibular swelling with tongue elevation. Because difficult airway had been suspected by preoperative assessment, feasible options of intubation in our hospital, including laryngeal mask, fiberoptic intubation and transtracheal jet ventilation, were prepared prior to induction of anesthesia. Anesthetic induction was carried out with propofol and suxamethonium, and subsequently tracheal intubation could be performed with difficulty under condition of partial visualization of vocal cord. Anesthetic maintenance with local anesthesia and continuous infusion of propofol 6 mg.kg-1.hr-1 was carried out during tracheostomy procedure, and this procedure was done uneventfully. Because airway control still remains a top priority in Ludwig's angina, feasible options of airway control should be prepared before induction of anesthesia if tracheostomy was required in a patient with this disease.

    A 20 year-old female in her 32nd week of gestation presented to the Emergency Department with dysphonia and dysphagia associated to a recent recurrence of a periapical abscess. Her oral examination showed trismus, elevated tongue and neck swelling. A clinical diagnosis of Ludwig's angina was reached, and empirical antibiotic coverage was started. The decompression and drainage placement was performed successfully under local anesthesia without airway compromise. At the moment, no clear guidelines exist for the acute treatment of Ludwig's angina. Establishment of a secure airway has long been considered the gold standard, yet new literature suggests a more conservative management. Ascertaining an early diagnosis at the Emergency Department, and involvement of Anesthesia, Obstetrics, and, Ear, Nose and Throat specialist services is vital for materno-fetal wellbeing. Careful evaluation of the airway status in addition to prompt antimicrobial therapy with surgical decompression may represent a plausible alternative in pregnant patients.

    Ludwig's angina (LA) is an infection of the submandibular space, first described by Wilhelm Frederick von Ludwig in 1836. It represents an entity difficult to manage due to the rapid progression and difficulty in maintaining airway patency, a major challenge in medical practice, resulting in asphyxia and death in 8-10% of patients. Describe a case of a patient with Ludwig's angina undergoing surgery, with emphasis on airway management, in addition to reviewing the articles published in the literature on this topic. Male patient, 21 years, drug addict, admitted by the emergency department and diagnosed with LA. Difficult airway was identified during the anesthetic examination. In additional tests, significant deviation from the tracheal axis was seen. Undergoing bilateral thoracoscopic pleural drainage, we opted for airway management through tracheal intubation using fiberoptic bronchoscopy, and balanced general anesthesia was proposed. There were no complications during the surgical-anesthetic act. After the procedure, the patient remained intubated and mechanically ventilated in the intensive care unit. Airway management in patients with Ludwig's angina remains challenging. The choice of the safest technique should be based on clinical signs, technical conditions available, and the urgent need to preserve the patient's life.

    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.

    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

    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.

    Despite the amply evidence and guidelines in treating coronary artery disease (CAD) with lipid-lowering therapy, physicians still have concerns in treating acute myocardial infarction (AMI) patients who have the low serum lipid level. We explored the adequacy of lipid-lowering therapy in treating AMI patients. Over 3000 CAD lipid profile data were collected, their data were divided into 3 groups (AMI; stable angina pectoris (SAP) and unstable angina pectoris (UAP) group) based their clinical characteristics. Statistical analyses were performed to compare their baseline lipid levels and clinical feature. The total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) level in AMI patients were the lowest, followed by UAP patient group and SAP patient group. There were significant differences in white blood count (WBC) and ejection fraction (EF) between 3 groups. A good correlation was confirmed between EF% and the lipid parameters of TC, LDL-c, HDL-c, non-HDL-c. WBC did not correlate with the lipid except HDL-c. AMI is an acute inflammatory reaction that is accompanied with the change of lipid level. Although the level of TC, LDL-c and HDL-c are lower in AMI, but it is related with acute inflammatory reaction during the rupture of atherosclerotic plaques. Lipid-lowering therapy should not be delayed in treating AMI patients with lower lipid level.

    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

    Ludwig's angina is a rapidly progressing cellulitis involving the submandibular neck space. It is characterized by brawny induration of the submental region and floor of mouth, bearing the potential for rapid airway obstruction. Airway management, antibiotics, and judicious surgical intervention are the mainstays of successful therapy. We present a case of Ludwig's angina in a 5-year-old child and offer a meta-analysis of pediatric cases of Ludwig's angina described in the literature over the past 30 years. The presentation, etiology, management, and potential complications of this disorder in the pediatric population are discussed.

    In order to evaluate the effects of acupuncture in moderate, stable angina pectoris, 49 patients were randomized to either genuine or sham acupuncture. In sham acupuncture needles were inserted into points within the same spinal segment as in genuine acupuncture, but outside the Chinese meridian...... system. The effect was evaluated from exercise tests, anginal attack rate and nitroglycerin consumption. There were no significant differences between the effects of genuine and sham acupuncture either on exercise test variables or on subjective variables. In patients receiving genuine acupuncture...... there was a significant increase in exercise tolerance (median 9%) and in delay of onset to pain (median 10%). No significant changes were observed in patients receiving sham acupuncture. Within both groups there was a median reduction of 50% in anginal attack rate and nitroglycerin consumption...

    Dilatation of the pulmonary artery may lead to the compression of adjacent structures. Of those, the extrinsic compression of the left main coronary artery is the most worrisome. We present the case of a 48-year-old woman who was diagnosed with pulmonary artery dilatation due to severe, thromboembolic pulmonary hypertension. She also had angina and coronary angiography revealed a 70% ostial stenosis of the left main coronary artery. The presence of this isolated lesion in a young woman without risk factors for atherosclerosis suggests extrinsic compression of the left main coronary artery by the dilated pulmonary artery as the likely mechanism. The patient underwent direct stenting of the left main coronary stenosis with a good result.

    Full Text Available Myocardial ischemia in pediatric population is uncommon and usually due to congenital heart disease or extracardiac conditions leading to poor coronary perfusion. A 6-day-old newborn presented with respiratory distress and signs of heart failure. ECG, echocardiography, and laboratory results were consistent with myocardial ischemia. Coronary angiography was performed to exclude anomalous origin of coronary arteries, showing normal coronary artery origin and course. Thrombophilia and extra-cardiac causes were ruled out. Clinical conditions improved with mechanical ventilation and diuretics, enzyme levels lowered, repolarisation and systolic function abnormalities regressed, but ischemic electrocardiographic and echocardiographic signs still presented during intense crying. Becaues of suspicion of microvascular angina, therapy with ASA and beta-blocker was started. At 5 month followup, the baby was in good clinical condition and no more episodes were recorded. We believe it is an interesting case, as no similar cases have been recorded till now.

    Thirty patients who had severe incapacitating angina pectoris which had not reacted to the conventional therapeutic measures and which required massive daily opioid consumption were treated with electrical spinal cord stimulation (SCS) by means of a completely implantable stimulation system....... The therapeutic effect was good in 87% of the patients who experienced considerably reduced frequency of attacks and markedly reduced opioid consumption (p less than 0.00005). Nine of the patients could reduce opioid consumption and 14 out of 27 could cease their otherwise daily opioid consumption. In four...... patients, the therapeutic effect was unsatisfactory. In the first 22 patients in whom a unipolar electrode was introduced, displacement of the electrode and subsequent reoperation was a frequent problem. This problem disappeared after change to multipolar electrodes as slight changes in placing...

    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.

    Full Text Available La inestabilidad en la combustión es una condición indeseada en algunos sistemas de combustión como en turbinas de gas por ejemplo. Se refiere a la presencia autogenerada de oscilaciones en la presión que pueden afectar a la cámara de combustión y de paso llegar a generar ruido. Una reciente tendencia generalizada en los procesos de combustión apunta al uso de mezclas pobres para la reducción de contaminantes, no obstante que este tipo de mezclas son más susceptibles a la inestabilidad en la combustión. Las complicadas relaciones que gobiernan el fenómeno se pueden resumir como el acoplamiento entre la llama y la acústica del sistema. En el presente trabajo se presenta un planteamiento numérico que permite aproximarse al fenómeno a través de la solución de un modelo de combustión básico implementado computacionalmente. En este modelo se simula una autoexcitación del sistema a través de oscilaciones en la entrada de flujos de reactantes. Finalmente, se comparan los resultados de la simulación numérica con otras simulaciones y datos experimentales.The Combustion instability is an undesirable condition reached in some combustion systems, as during the operation of gas turbines. It refers to self-excited oscillations of pressure that may affect the combustion chamber and generate noise. A recent generalized tendency in combustion processes aims to the use of lean combustion (low fuel/air ratios for pollutants reduction, nevertheless this sort of mixtures are more susceptible to combustion instabilities. The complex relationship that generates the phenomenon can be summarized as the coupling between flame and acoustics. In this paper it is outlined a numerical approach to this phenomenon by solving a basic computational combustion model (by Direct Numerical Simulation. In this model a self-excited system is simulated through imposed oscillations in reactants flows. Finally, results for this numerical simulation are compared

    To compare the characterization of coronary atherosclerotic plaques in patients with unstable angina pectoris (UAP) and stable angina pectoris (SAP) by optical coherence tomography (OCT). OCT was performed in 47 patients (23 UAP and 24 SAP) undergoing coronary angiography. Lipid-rich plaque (defined by > or = 2 quadrants of the cross-section area), thin cap fibroatheroma (TCFA), thickness of fibrous cap, plaque rupture, calcification and thrombus visualized by OCT were compared between UAP and SAP patients. OCT imaging was successfully in 44 out of 47 patients (22 UAP, 22 SAP). Proportion of lipid-rich plaques was similar between UAP and SAP groups [91% (20/22) vs. 73% (16/22), P = 0.741]. The minimum thickness of fibrous cap in the UAP group was significantly thinner than that in SAP group [(69.5 +/- 34.7) microm vs. (141.1 +/- 68.5) microm, P = 0.000] and the rate of fibrous cap erosion in the UAP group was significantly higher than that in the SAP group [59% (13/22) vs. 9% (2/22), P = 0.000]. Percents of TCFA [73% (16/22) vs. 14% (3/22), P = 0.000] and plaque rupture [50% (11/22) vs. 9% (2/22), P = 0.003] were significantly higher in UAP group compared those in SAP group. Incidence of thrombus and calcification were similar between two groups. OCT imaging can clearly define plaque characterization of coronary atherosclerosis. UAP patients have thinner fibrous cap, higher incidences of fibrous cap erosion, plaque rupture and TCFA compared patients with SAP.

    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

    OBJECTIVES: CMD could be the explanation of angina pectoris with no obstructive CAD and may cause ventricular repolarization changes. We compared T-wave morphology and QTc interval in women with angina pectoris with a control group as well as the associations with CMD. METHODS: Women with angina...... pectoris and no obstructive coronary artery disease (n=138) and age-matched controls were compared in regard to QTc interval and morphology combination score (MCS) based on T-wave asymmetry, flatness and presence of T-wave notch. CMD was assessed as a coronary flow velocity reserve (CFVR) by transthoracic...... was attenuated after multivariable adjustment (p=0.08). CONCLUSION: This study suggests that women with angina pectoris have alterations in T-wave morphology as well as longer QTc interval compared with a reference population.

    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

    Full Text Available 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.

    Unstable angina is a clinical diagnosis that may present with or without electrocardiographic changes. The "giant R wave" on electrocardiogram has been reported as a manifestation of acute ischemia; however, it is a rare finding in current clinical practice. We describe a case of a patient with unstable angina and a transient "giant R wave" pattern with a culprit lesion in the right coronary artery.

    The study of angina prevalence has received little attention in the analysis of the dimension of coronary heart disease. The aim of this study was to determine the prevalence of angina and cardiovascular risk factors in the 45- to 74-year-old population of the different autonomous regions of Spain. A sample of 10,248 subjects was recruited. Sampling was stratified by gender and age groups (45-54, 55-64 and 65 to 74 years), and proportional to the population distribution of the different autonomous regions. A multistage sampling was performed, firstly 200 villages were randomly selected, secondly three different socio-economic household were chosen. Sample unit was neighbouring households. Rose questionnaire of angina and a structured questionnaire to collect socio-demographic and risk factor variables were administered. Angina prevalence in the 45- to 74-year-old Spanish population was 7.5%. The autonomous regions with the higher and lower prevalence were Baleares (11.4%) and Basque Country (3.1%), respectively. The Pearson correlation coefficient between angina prevalence and ischemic heart disease or cardiovascular disease mortality in men and women was 0.52 and 0.55, and 0.31 and 0.44, respectively. The self reported prevalence of hypertension, dyslipemia, diabetes and smoking was 31.1%, 24.2%, 14.3% and 34.6% respectively. Angina prevalence in Spain is similar to that of developed countries although significant differences were observed among the autonomous regions of Spain. These differences correlate with those observed in ischemic heart disease or cardiovascular mortality among them and are associated with the cardiovascular risk factors prevalence which also varies among communities.

    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

    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.

    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.

  5. Angina pectoris in patients with HIV/AIDS: prevalence and risk factors

    Josefina Cláudia Zirpoli

    Full Text Available INTRODUCTION: 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. OBJECTIVE: 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. METHOD: 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. RESULTS: 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. CONCLUSION: This study suggests that angina pectoris is underdiagnosed, even in patients with medical monitoring, revealing lost opportunities in identification and prevention of cardiovascular morbidity.

  6. Critical evaluation of ivabradine for the management of chronic stable angina

    Full Text Available Waqas Khan, Jeffrey S BorerDivision of Cardiovascular Medicine and the Department of Medicine, State University of New York Downstate Medical Center and College of Medicine, Brooklyn and New York, NY, USAAbstract: Angina pectoris is the most common symptom of coronary artery disease (CAD. Angina results from an imbalance between myocardial oxygen supply and demand. Heart rate (HR reduction can beneficially alter both elements of this imbalance by increasing diastolic filling time and reducing myocardial oxygen demand. Therefore, HR reduction is an accepted approach to angina prevention. ß-blockers, calcium-channel blockers, and long-acting nitrates are currently the cornerstones in prevention and management of stable angina. However, use of these treatments may be limited by adverse effects or development of tolerance. Thus, additional approaches to angina prevention may be useful for many patients with CAD. The discovery of the f-channel and the resulting current, If, that modulates the rate of spontaneous diastolic depolarization of sinoatrial nodal (SAN myocytes led to the study of these channels as targets for lowering HR. This resulted in the development of a novel agent, ivabradine, a selective and specific If inhibitor. Ivabradine slows the slope of diastolic depolarization of the action potential in the SAN cells, decreasing HR at rest and during exercise, but has no other cardiovascular effects. In different subpopulations with chronic stable angina, ivabradine markedly improves exercise capacity and significantly decreases the number of ambient angina attacks. In a post-hoc analysis of the BEAUTIFUL trial (morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with coronary disease and left-ventricULar dysfunction, ivabradine also reduced mortality, myocardial infarctions, and heart failure hospitalizations among patients with angina.

    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)

    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.

    To evaluate the clinical efficacy of safflower yellow injection combined with conventional therapy in treating unstable angina pectoris. We searched online databases: Chinese journal full-text database, China National Knowledge Infrastructure, Wanfang database, Chinese journal full-text database, Pubmed, ScienceDirect, Embase, and the Cochrane Library with manual-screening of relevant literature. Eligible randomized controlled trials (RCT) on angina pectoris were included. We conducted meta-analysis using the RevMan 5.1 software from The Cochrane Collaboration. We treated the relief rate of angina symptoms and electrocardiograph (ECG) as evaluation. Seven articles, including in 1134 patients, were enrolled after the evaluation. There was no significant heterogeneity among the studies (chi2 = 1.08, df = 6, P = 0.98, I2 = 0%). The safflower yellow injection with conventional therapy has a higher effective rate than the control group in relieving the symptoms of angina pectoris [odds ratio (OR)= 2.95, 95% (CI) (1.81, 4.81)] and improving ischemic ECG [OR = 2.85, 95% CI (1.67, 4.86)]. The difference was statistically significant in the "80 mg dosage" and "100 mg dosage" subgroups (P unstable angina and improving ECG over basic therapy alone. However, the conclusions should be interpreted with care until more high-quality RCTs are reported.

    Two cases of Ludwig's angina treated successfully led us to review the main English language literature from 1945 to January 1979. The most common cause of Ludwig's angina is dental, and the organism cultured most often is streptococcus. However, other avenues of infection and numerous pathogens have been implicated in this disease. Penicillin remains the preferred primary antibiotic, with combinations of this drug and other antibiotics being used by various authors. In both the pre-antibiotic and antibiotic era, the airway remains the prime concern of the surgeon in the management of this potentially life-threatening disease. Of the 75 cases reviewed, there were seven deaths, but four of these patients had pre-existing fatal systemic problems and Ludwig's angina was not the cause of death. The other three deaths were due to Ludwig's angina, yielding a 4% mortality rate. Thus, aggressive management of Ludwig's angina, with respect to airway, antibiotics, and early surgical intervention, has resulted in a significant drop in the mortality rate of this disease which once led "almost uniformly to a fatal ending."

  13. Newer Therapies for Management of Stable Ischemic Heart Disease With Focus on Refractory Angina.

    Singh, Mukesh; Arora, Rohit

    Ischemic heart disease remains a major public health problem nationally and internationally. Stable ischemic heart disease (SIHD) is one of the clinical manifestations of ischemic heart disease and is generally characterized by episodes of reversible myocardial demand/supply mismatch, related to ischemia or hypoxia, which are usually inducible by exercise, emotion, or other stress and reproducible-but which may also be occurring spontaneously. Improvements in the treatment of acute coronary syndromes along with increasing prevalence of cardiovascular risk factors, including diabetes and obesity, have led to increasing population of patients with SIHD. A significant number of these continue to have severe angina despite medical management and revascularization procedures performed and may progress to refractory angina. This article reviews the newer therapies in the treatment of SIHD with special focus in treating patients with refractory angina.

    We diagnosed and treated a case of Ludwig's angina in a 45-year-old man who had edema of the floor of mouth and the tongue along with bilateral submandibular sialadenitis and sialolithiasis. We secured the patient's airway via nasal fiberoptic intubation in the surgical intensive care unit and administered intravenous antibiotics. The edema subsided, and the patient was extubated on the third postoperative day and discharged shortly thereafter. To our knowledge, this is the first reported case of a patient with bilateral submandibular sialadenitis and sialolithiasis presenting as Ludwig's angina. Despite the decreasing incidence of this disease, Ludwig's angina remains an important disease process because a failure to control the airway can have disastrous consequences. Proper diagnosis, airway control, antibiotic therapy, and occasionally surgical management are essential to ensure the safety of the patient.

    Objectives. To review the current protocols used for management of Ludwig's angina and to assess the efficacy of conservative measures in these cases. Methods. A retrospective review of patients who were admitted to our institution for management of Ludwig's angina between 2003 and 2010. Results. Two patients were identified. Both were managed successfully with conservative measures and close airway observation. None needed an emergency intubation or surgical tracheostomy. There were no mortalities, and both had a short hospital stay. Conclusion. Recently, management of Ludwig's angina has evolved from aggressive airway management into a more conservative one. This is based on close airway observation on a specialised airway unit and a serial clinical airway assessment. Improved imaging modalities, antibiotic therapy, surgical skills, and clinical experience are the key factors behind this change in practice.

    Ludwig's angina is a serious and rapidly progressive infectious process that spreads through the floor of the mouth and neck. In this paper we present an infrequent case of a patient who suffered an odontogenic infection with poor response to the previous treatment, which evolved towards a Ludwig's angina combined with ketoacidosis in the context of a diabetes mellitus not known before. According to the literature reviewed, this case report represents the first contribution of a Ludwig's angina and ketoacidosis as an initial manifestation of a diabetes mellitus. The airway management, the antibiotic prescription and the surgical drainage allowed the healing of the patient without medical complications. Factors of co-morbidity like the diabetes mellitus together with focus tooth of infection may eventually turn into serious medical complications as the diabetic ketoacidosis and develop potentially lethal cervical infections.

    Temporary sympathectomy by injection of bupivacaine at the site of the left stellate ganglion is used in the management of refractory angina at several UK centres. Although patients frequently report significant reduction in symptoms, efficacy has not been established by double-blind, randomised placebo-controlled trial (RCT). To investigate the efficacy of the procedure for the first time by a double-blind RCT. Consecutive patients referred to the authors' National Health Service (NHS) angina centre who were candidates for temporary sympathectomy were invited to participate in a trial. A total of 65 patients were randomised to receive either bupivacaine or saline injections. Identical syringes were prepared remotely, blinding patients and staff from randomisation. Cardiac autonomic function was measured 3 hours pre- and post-injection using new heart rate variability (HRV) analyses. Angina episodes were recorded contemporaneously by patients in study diaries in the 7-day periods pre- and post-injection. In 51 patients suitable for analysis, no significant differences between the active and placebo groups were found in patient-recorded frequency or intensity of angina episodes pre- and post-injection. However, across both groups combined, a significant difference was found in the frequency of angina episodes pre- and post-injection. The reduction in frequency of angina episodes produced by this procedure may not be due to drug pharmacology. It may be a placebo response or due to the mechanical effects of the injection of fluid. There is a need for further work using a larger patient cohort considering both mechanical and psychological factors.

    The present study is an angiographic demonstration of coronary artery spasm during both spontaneous and exercise-induced angina in three patients with variant angina. In each case, clinical, ECG, coronary angiographic, and left ventriculographic observations were made at rest, during spontaneous angina, and during exercise-induced angina. The character of chest pain was similar during spontaneous and exercise-induced episodes. ST segment elevation was present in the anterior ECG leads during both episodes. The left anterior descending coronary artery became partially or totally obstructed during both types of attacks. When coronary spasm was demonstrated during both types of attacks, left ventriculography disclosed akinetic or dyskinetic wall motion in the area supplied by the involved artery. In those patients with reproducible exercise-induced ST segment elevation and chest pain, thallium-201 scintigraphy showed areas of reversible anteroseptal hypoperfusion. Thus in selected patients exercise-induced attacks of angina were similar to spontaneous episodes

To evaluate antianginal efficacy and safety of nicorandil for angina attack prevention and relief in patients with ischemic heart disease (IHD and symptoms of stable angina class 2-3.Material and methods. 30 patients with stable angina class 2-3 (17 men, 13 women; aged 58.6±5.8 y.o. were included into the study. All patients received amlodipine 10 mg QD within 2 weeks. For angina attack relief patients used nicorandil 10-20 mg and in case of its inefficacy — nitroglycerin. In 2 weeks all patients were randomized in 2 groups. Patients of the 1st group (n=15 received nicorandil 20 mg TID, patients of the 2nd group (n=15 — amlodipine 10 mg QD. The study duration was 3 months. The efficiency evaluation was based on the analysis of hemodynamic indicators (heart rate, blood pressure, bioelectric heart activity (electrocardiogram, velocity exercise tolerance test, ambulatory blood pressure monitoring indicators. The pain severity was defined with Borg's scale, and the quality of life — with General Health Questionnaire (GHQ-28. Therapy safety was evaluated in according to laboratory tests results.Results. Frequency of angina attacks reduced by 60% (р<0.05 and 47% (р<0.05 in 12 weeks of nicorandil and amlodipine therapy, respectively. Duration of angina decreased by 38% and 37% (р<0.05 in 12 weeks of nicorandil and amlodipine therapy, respectively. Eexercise duration before angina attack onset increased by 56% (р<0.05 in 1 month of nicorandil therapy. A number of myocardial ischemia episodes reduced by 64% (р<0.05 and 54% (р<0.05 due to nicorandil and amlodipine therapy, respectively. General GHQ-28 score decreased by 54% (р<0.05 and 44% (р<0.05 in patients of the 1st and the 2nd groups, respectively. Tolerability of nicorandil was good in 13 (86.7% and satisfactory in 2 (13.3% patients.Conclusion. Nicorandil can be prescribed both for the prevention and for relief of angina attacks in IHD patients.

    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

    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.

    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

    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.

    To compare the efficacy and safety profile of dalteparin, a low-molecular-weight heparin with a standard unfractionated heparin in patients with unstable angina pectoris. This was a 6-month, prospective, parallel, randomized and open-labeled study. Patients of angina pectoris were randomized to receive either unfractionated heparin or dalteparin for 5 days. They were followed for 21 days during three visits on 1(st), 5(th) and 21(st) days. A series of resting electrocardiogram were undertaken in all patients on each visit. The frequency of the combined clinical outcome of death, myocardial infarction and recurrence of angina was similar during 21 days of follow-up with either dalteparin or intravenous unfractionated heparin. In patients who received dalteparin 2.43% patients developed minor bleeding in the form of epistaxis and 2.5% patients who received unfractionated heparin developed minor bleeding in the form of macroscopic hematuria. Dalteparin is as effective and safe as unfractionated heparin in the treatment of unstable angina. Dalteparin does not require routine laboratory monitoring as with unfractionated heparin.

    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 unstable angina pectoris is conducive in standardizing the diagnosis and treatment behaviors of the hospital and reducing economic burdens among patients.

    Some patients of ischemic heart disease have low uptake in {sup 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)

    Wolfe, Mary M; Davis, James W; Parks, Steven N

    2011-02-01

    Deep neck infections are potentially life-threatening conditions because of airway compromise. Management requires early recognition, antibiotics, surgical drainage, and effective airway control. The Surgical Education and Self-Assessment Program 12 states that awake tracheostomy is the treatment of choice for these patients. With advanced airway control techniques such as retrograde intubation, GlideScope, and fiberoptic intubation, surgical airway is not required. A retrospective analysis of all deep neck abscesses treated from December 1999 to July 2006 was performed. All patients who underwent urgent or emergent surgery for Ludwig angina and submental, submandibular, sublingual, and parapharyngeal abscesses (Current Procedural Terminology codes 41015, 41016, 41017, 42320, and 42725) were included in our review. Charts were studied for age, presence of true Ludwig angina, presence of airway compromise, airway management, morbidity/mortality, and the requirement for surgical airway. Of 29 patients, 6 (20%) had symptoms consistent with true Ludwig angina. Nineteen (65.5%) had evidence of airway compromise. Eight (42%) of these 19 patients required advanced airway control techniques. No patient required a surgical airway, and no mortality resulted from airway compromise. Advance airway control techniques were required more often in patients with airway compromise (P Ludwig angina and deep neck abscesses requires good clinical judgment. Patients with deep neck infections and symptoms of airway compromise may be safely managed with advanced airway control techniques. Copyright © 2011 Elsevier Inc. All rights reserved.

    To review Ludwig's angina medical and surgical approach with small incisions. Retrospective, open, noncomparative, longitudinal. All patients with Ludwig's angina who received medical, metabolic, airway management, and surgical treatment from January 1, 1983 to December 31, 2000. Antibiotic treatment, surgical treatment, hospitalization time, associated diseases, etiologic factors, recuperation time. Age range was 18 to 87 years, with a female-to-male ratio of 1.1:1 (68 females, 53 males). Thirty patients belonged to middle or high socioeconomic status. The primary site of infection was odontogenic in 107 of the patients. All the patients were managed with surgical drainage made within the first 12 hours after hospital admission. The most common antibiotic treatments were the combination of clindamycin with crystalline penicillin G. The hospital stay for more than half of patients was 6 days or less. In 62 patients we found extension into the parapharyngeal space and in 32 cases we found retropharyngeal extension of the Ludwig's angina. Forty-six patients had or were diagnosed as having diabetes mellitus. Tracheotomy was required in 34 patients. The airway of the rest of patients was controlled with nasotracheal intubation. Only 33 patients had major complications, such as mediastinitis, sepsis, or death. Drainage using small incisions is a safe and effective method as part of treatment of Ludwig's angina.

    Patients with Systemic Lupus Erythematosus (SLE) carry an increased risk for the development of coronary artery disease (CAD). The R131 allele of the Fc gamma receptor IIa (FcγRIIa) is associated with SLE incidence and disease severity but also with CAD. Compared to stable angina pectoris (SAP) the unstable angina (UAP), as a manifestation of destabilizing CAD, is associated with increased risk of persistent instability, myocardial infarction, and death. Identification of clinically relevant determinants for unstable angina promises reduction of UAP-associated mortality in patients with SLE. We conducted a clinical study among 553 consecutive patients with stable angina pectoris (n = 330) and unstable angina pectoris (n = 223). All patients were genotyped for a frequent functional variant at position 131 of the mature FcγRIIa. UAP, but not SAP was significantly associated with the R/R131 genotype (P angina carrying the R/R131 genotype the odds ratio for suffering from UAP was 4.02 (95% confidence interval, 2.52-6.41) compared to those with non-R/R131 genotypes. In a multivariable analysis, the R/R131 genotype independently predicted the risk for development of UAP in a model adjusted for classical atherogenic risk factors. Our data imply that risk stratification of SLE- and other high risk patients with troponin-negative angina could be significantly improved by FcγRIIa genotyping.

    2004-01-01

    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 treatment of patients with angina pectoris refractory to medical therapy and unsuitable for revascularization procedures has yet not been well standardized. Previous retrospective studies and small prospective studies have suggested beneficial effects of spinal cord stimulation (SCS) in these patients. We created a Prospective Italian Registry of SCS to evaluate the short- and long-term clinical outcome of patients who underwent SCS device implantation because of severe refractory angina pectoris. Overall, 104 patients were enrolled in the registry (70 men, aged 68 +/- 17 years), most of whom (83%) had severe coronary artery disease. Average follow-up was 13.2 +/- 8 months. Overall, 17 patients (16%) died, 8 (8%) due to cardiac death. Among clinical variables, only age was found to be significantly associated both with total mortality (p = 0.04) and cardiac mortality (p = 0.02) on Cox regression analysis. A significant improvement of anginal symptoms (> or =50% reduction of weekly anginal episodes, compared with baseline) occurred in 73% of patients, and Canadian Cardiovascular Society angina class improved by > or =1 class in 80% and by > or =2 classes in 42% of patients, with a relevant reduction in the rate of hospital admission and days spent in the hospital because of angina (p <0.0001 for both). No life-threatening or clinically serious complications were observed. The most frequent side effect consisted of superficial infections, either at the site of puncture of electrode insertion or of the abdominal pocket, which occurred in 6 patients. In conclusion, our prospective data point out that SCS can be performed safely and is associated with a sustained improvement of anginal symptoms in a relevant number of patients with refractory stable angina pectoris.

    Recent reports have suggested that cytomegalovirus (CMV) infection may contribute to risk of cardiovascular disease. However, relationship between CMV infection and unstable angina (UA) is controversial and studies about this subject in Iran and even region are lacking. The aim of this study was to determine whether unstable angina is related to seropositivity to chronic cytomegalovirus infection. We measured serum CMV IgG levels in a case control study participants in CCU in Razi Hospital, Ahvaz, Iran, from 2004 to 2005. Blood samples were drawn during study period from 96 patients (mean age 56 years) with UA according to American Heart Association Criteria and from 96 participants free of cardiovascular disease (mean age 58 years) and stored at -20°C. Blood samples of patients were undertaken for investigating the specific anti CMV-IgG by ELISA method. Data were analyzed in SPSS 11.5 by using chi square test, odds ratios (OR) with 95% confidence intervals (CI). Ninety three percent of patients with unstable angina and 96.7% in the control group presented a positive anti CMV-IgG. Odds ratio was 0.52 with 95% CI: 0.10 to 2.42. There was no significant correlation between CMV-IgG positivity and unstable angina (P>0.05). There was also no differences in CMV-IgG positivity in clinical groups of UA (P>0.05). The relationship between seropositivity of CMV-IgG and unstable angina has been restituted by the results of this study. However, further population based cohort studies for relationship between CMV infection and coronary artery disease must be conducted.

    A 61-year-old man presented with recurrent angina pectoris at rest for 3 days. The medical history revealed hypertension and an elevated cholesterol level as cardiovascular risk factors. The physical examination revealed no pathological findings. ECG at admission showed no signs of ischemia, while high-sensitive Troponin T was slightly elevated. Echocardiography showed diastolic dysfunction and biatrial dilatation. During another episode of angina at rest, ECG showed T-wave inversion in lead aVL. Therefore, coronary angiography was performed. At the beginning of the examination the patient complained of angina at rest and ECG showed ST-elevation in the inferior leads. Coronary angiography revealed a subtotal stenosis in the middle part of the RCA. After intracoronary nitroglycerin injection there was a high-grade stenosis in this region. An intracoronary acetycholin provocation test was performed which reproduced a focal spasm in the area of the RCA stenosis with simultaneous changes in the ECG and reproduction of the patient's unusual angina. After implantation of a bare metal stent a subsequent ACH-test did not elicit any further coronary spasm. Four weeks after the procedure the patient had no further complaints under medical treatment. This case illustrates a patient with a focal Prinzmetal-type spasm with ST-elevation on top of a high-grade stenosis of the right coronary artery as an explanation for the unstable angina. Coronary spasm of the Prinzmetal-type can occur in vessels with epicardial stenosis as well as in vessels without stenosis. In some cases focal coronary spasm can be prevented by the implantation of a stent. © Georg Thieme Verlag KG Stuttgart · New York.

  19. Thunderclap-like headache triggered by micturition and angina as an initial manifestation of bladder pheochromocytoma. A case report

    Directory of Open Access Journals (Sweden)

    You Jin Han

    Full Text Available CONTEXT: Pheochromocytoma is a catecholamine-producing tumor characterized by hypertension, headache, tachycardia, excessive diaphoresis and angina. The thunderclap headache is so named because the pain strikes suddenly and severely. Although the symptoms of bladder pheochromocytoma are rather evident, the diagnosis of this rare neuroendocrine tumor can be missed. CASE REPORT: This study reports the case of a woman diagnosed with bladder pheochromocytoma who experienced thunderclap headache triggered by micturition and angina as an initial manifestation. CONCLUSION: This case study suggests that thunderclap headache and angina occurring concurrently with sudden blood pressure elevation during or immediately after micturition are important diagnostic clues for bladder pheochromocytoma.

    The EARISA Registry was designed to describe diagnostic and therapeutic resources used in Italian cardiology centers for patients with the epidemiologically most relevant cardiac diseases. This article focuses on patients with unstable angina; characteristics associated with invasive procedures were specifically analyzed. Information was collected over a 2-week period on 1420 patients with unstable angina discharged from 308 cardiology centers. The mean length of stay was 9 +/- 6 days; 51% of patients were admitted to a coronary care unit (mean length of stay, 4 +/- 3 days). Noninvasive procedures included echocardiography (64%), Holter monitoring (25%), exercise stress testing (24%), and echocardiographic stress testing or nuclear imaging (7%). Invasive procedures were coronary angiography (39%) and percutaneous transluminal coronary angioplasty or coronary artery bypass grafting (13%). Unstable angina had a greater impact on invasive procedures than acute myocardial infarction. Variables independently associated with a higher rate of coronary angiographic procedures were younger age, higher technologic level of the hospital, and need for intravenous therapy. In Italy, approximately half the patients with unstable angina are admitted to hospitals without catheterization laboratories or cardiac surgery facilities. This fact supports the concept that treatments that can be administered in all types of hospitals are more likely to affect the outcome of patients with unstable angina. Overall, the rates of coronary angiography and revascularization procedures appeared low, and the setting where cardiologists practice, rather than patient characteristics, is the major determinant of the care given to patients with unstable angina.

    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

    Cardiac Syndrome X (CSX) was considered a stable coronary syndrome, yet due to its nature, CSX symptoms often have a great impact on patients’ Quality of Life (QoL). According to ESC 2013 stable coronary artery disease criteria, CSX was replaced by Microvascular Angina (MA).Unfortunately, most CSX or MA patients, after classical angina (involving main coronary vessels) has been ruled out, often do not receive proper treatment.

    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.

    In a randomized double-blind study, treatment with either metoprolol, nifedipine, or their combination was compared for effects on ischemic variables and heart rate obtained during ambulatory monitoring in 42 patients with chronic stable angina. All patients had severe chronic stable angina...... of at least 6 months' duration despite medical treatment, and exhibited coronary artery stenosis of 75% in one or more coronary arteries. Metoprolol reduced the frequency of total (p less than 0.01) and asymptomatic ischemic episodes (p less than 0.05), the duration of ischemia (p less than 0.......05), and the ischemic burden (p less than 0.05), which contrasted to the lack of any similar significant effect during nifedipine monotherapy. During combination therapy, there was a tendency to further improvement, which did not reach statistical significance compared with metoprolol monotherapy. Heart rate...

    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.

    Bronchiectasis is characterized by the abnormal and permanent dilatation of bronchi. Clinical manifestations of bronchiectasis include persistent or recurrent cough, purulent sputum, hemosputum, and hemoptysis. A 75-year-old man with bronchiectasis required coronary bypass grafting for unstable angina pectoris with severe stenosis of the left main trunk. Computed tomography showed fistulae between the dilated bronchial arteries and the left pulmonary artery. Cardiac catheter examination showed significant left-right shunt and left ventricular dilatation. To avoid perioperative massive hemoptysis, embolizations of 2 bronchial arteries and an inferior phrenic artery were performed preceding the coronary artery bypass grafting. Both transcatheter embolization and coronary artery bypass grafting were successfully performed without any complications. Herein, we illustrate a very rare case of bronchiectasis in a patient with unstable angina pectoris who underwent transcatheter embolization for a systemic-pulmonary shunt preceding coronary artery bypass grafting with cardiopulmonary bypass.

    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.

    Diagnostic models used in the management of suspected angina provide no explicit information about prognosis. We present a new prognostic model of 10-year coronary mortality in patients presenting for the first time with suspected angina to complement the Diamond-Forrester diagnostic model of disease probability. A multicentre cohort of 8762 patients with suspected angina was followed up for a median of 10 years during which 233 coronary deaths were observed. Developmental (n=4412) and validation (n=4350) prognostic models based on clinical data available at first presentation showed good performance with close agreement and the final model utilised all 8762 patients to maximise power. The prognostic model showed strong associations with coronary mortality for age, sex, chest pain typicality, smoking status, diabetes, pulse rate, and ECG findings. Model discrimination was good (C statistic 0.83), patients in the highest risk quarter accounting for 173 coronary deaths (10-year risk of death: 8.7%) compared with a total of 60 deaths in the three lower risk quarters. When the model was simplified to incorporate only Diamond-Forrester factors (age, sex and character of symptoms) it underestimated coronary mortality risk, particularly in patients with reversible risk factors. For the first time in patients with suspected angina, a prognostic model is presented based on simple clinical factors available at the initial cardiological assessment. The model discriminated powerfully between patients at high risk and lower risk of coronary death during 10-year follow-up. Clinical utility was reflected in the prognostic value it added to the updated Diamond-Forrester diagnostic model of disease probability. Published by the BMJ Publishing Group Limited.

Patients with T2DM have more extensive CAD and present at a younger age; therefore, identification and management of chronic angina in these patients presents an opportunity to limit both cardiovascular symptoms and adverse outcomes. This article reviews the role of screening and treatment for chronic angina in patients with T2DM. There is a strong evidence base for modifying lifestyle as a way of reducing adverse cardiovascular outcomes in the diabetic population and this article reviews evidence of lifestyle modification as an important and necessary adjunct to pharmacologic intervention. Management of chronic stable angina is addressed by looking at treatments that reduce ischemic symptoms and those that reduce adverse cardiovascular outcomes. Trials specific to the diabetic population are limited, with information largely obtained from the diabetic subgroup analysis of large intervention trials. The growing diabetic population with increased propensity to cardiovascular disease mandates trials specifically in this patient population. Revascularization in patients with diabetes is associated with more complications than in the non-diabetic population. Recent trials specific to this population suggest surgical revascularization to be associated with better long-term outcomes and therefore, this article reviews the evidence for the optimal mode of revascularization in this population.

Patients were randomized into 2 groups (G1 and G2. G1 patients were treated with betaxolol, and G2 patients – with metoprolol tartrate. Ambulatory BP and electrocardiogram monitoring, exercise stress-test, echocardiography, evaluating of respiratory function, blood analysis was performed initially and in 30 and 90 days of treatment.Results. Target BP level was reached in 44 (88% patients treated with betaxolol (average daily dose 10±4 mg. 34 patients of G1 took 10 mg daily. Target BP level was reached in 41 (82% patients treated with metoprolol tartrate (average daily dose 150±27 mg. 30 patients of G2 took 150 mg daily. Exercise tolerance increased and a number of ischemic ST segment depressions reduced significantly in both groups. There were no significant differences in antihypertensive, antianginal, and antiischemic efficacy between groups.Conclusion. Betaxolol advantage is an ability to maintain target BP level more than 24 hours. A possibility to take betaxolol once a day raises patient’s compliance with therapy.

    We performed exercise thallium-201 myocardial scintigraphy in 32 patients with angina pectoris to study the incidence of perfusion defects, who had no significant organic stenosis on coronary angiography. 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)

    Puerarin is an effective ingredient isolated from Radix Puerariae, a leguminous plant. In China, a large number of early studies suggest that puerarin may be used in the treatment of coronary heart disease. In recent years, puerarin injection has been widely used to treat coronary heart disease and angina pectoris. To systematically evaluate the clinical efficacy and safety of puerarin injection in the treatment of unstable angina pectoris (UAP). Data were retrieved from digital databases, including PubMed, Excerpt Medica Database (EMBASE), China Biology Medicine (CBM), the Cochrane Library, and Chinese databases. Compared with patients who were treated with conventional Western medicines alone, the patients who were treated with conventional Western medicines in combination with puerarin injection exhibited significant improvements in the incidence of angina pectoris, electrocardiogram findings, nitroglycerin consumption and plasma endothelin levels. Strong evidence suggests that, the use of puerarin in combination with conventional Western medicines is a better treatment option for treating UAP, compared with the use of conventional Western medicines alone.

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 observe plasma vascular endothelial growth factor(VEGF) levels and related factors in patients with unstable angina pectoris(UAP). A total of 108 consecutive patients with chest pain hospitalized in our department from October to December 2014 were included. They were divided into UAP (n=78) and non-CHD group (n=30) by the result of coronary angiography(CAG). Coronary artery lesion was assessed according to the Gensini score, serum lipids, homocysteine(Hcy) levels and other biochemical indicators were also determined. The peripheral arterial tonometry was evaluated by reactive hyperemia index(RHI) measured by Endo-PAT2000 Noninvasive Diagnostic System.The level of plasma VEGF was detected in patients with unstable angina pectoris. Multiple linear regression analysis was used to analyze the correlations between VEGF and various related factors. Percent of male gender, triglyceride (TG) and Hcy levels were significantly higher in UAP group than in no-CHD group(all Punstable angina pectoris, and VEGF level is significantly associated with the degree of coronary artery stenosis, Gensini score and RHI. V EGF level might serve as a new biochemical indicator for coronary artery lesion in patients with UAP.

    To explore the correlation between common syndrome essential factors and the symptoms and signs of unstable angina (UA). Eight hundred and fifteen patients with UA confirmed by coronary angiography were identified from several centers. Common syndrome essential factors were selected on the basis of expert experience. The correlations between common syndrome essential factors and symptoms and signs of UA were analyzed using binary logistic regression analysis. The common syndrome essential factors in unstable angina were blood stasis, qi stagnation, phlegm turbidity, heat stagnancy, qi deficiency, yin deficiency, and yang deficiency. Symptoms such as chest pain, hypochondriac distention, ecchymosis, dark orbits, dark and purplish tongue, and tongue with ecchymosis and petechiae were significant diagnostic features of "blood stasis". Aversion to cold and cool limbs, weakness in the waist and knees, and clear abundant urine were significant diagnostic features of"yang deficiency". These results were in accordance with the understanding of traditional clinical Chinese medical practice. This clinical study analyzed the correlations between common syndrome essential factors and the symptoms and signs of unstable angina. The results provide the basis for establishing diagnostic criteria for syndrome essential factors.

    The left atrial size has been considered as a useful marker of adverse cardiovascular outcomes. However, it is not well known whether left atrial area index (LAAI) has predictive value for prognosis in patients with unstable angina pectoris (UAP). This study was aimed to assess the association between LAAI and outcomes in UAP patients. We enrolled a total of 391 in-hospital patients diagnosed as UAP. Clinical and echocardiographic data at baseline were collected. The patients were followed for the development of adverse cardiovascular (CV) events, including hospital readmission for angina pectoris, acute myocardial infarction (AMI), congestive heart failure (CHF), stroke and all-cause mortality. During a mean follow-up time of 26.3 ± 8.6 months, 98 adverse CV events occurred (84 hospital readmission for angina pectoris, four AMI, four CHF, one stroke and five all-cause mortality). In a multivariate Cox model, LAAI [OR: 1.140, 95% CI: 1.016-1.279, P = 0.026], diastolic blood pressure (OR: 0.976, 95% CI: 0.956-0.996, P = 0.020) and pulse pressure (OR: 1.020, 95% CI: 1.007-1.034, P = 0.004) were independent predictors for adverse CV events in UAP patients. LAAI is a predictor of adverse CV events independent of clinical and other echocardiographic parameters in UAP patients.

    To assess the efficacy and safety of Dengzhanxixin injection for unstable angina pectoris. All clinical studies of Dengzhanxixin injection for unstable angina pectoris (UAP) were searched from Cochrane library, Medline, EM-base, CBM, CNKI, Wanfang and VIP. Quality assessment and information extraction were done by two independent screening . The quality of the included documents was evaluated by the Cochrane Collaboration's tool for assessing risk of bias and allocation concealment. Revman 5.1.4 software was used for data analysis. A total of 17 randomized controlled trials were included (1 644 patients), in which, only 2 studies were true RCT, 1 study used single blind method, while other studies did not mention allocation concealment, blind and loss-up information. Meta-analysis showed that the Dengzhanxixin injection group was better than the conventional treatment group in efficiency (OR = 3.54, 95% CI [2.60-4.82]) and ECG (OR = 2.36, 95% CI[1.88-2.96]). Researches with ADR/AE information of Dengzhanxixin injection showed that the symptoms of ADR/AE were slight. This study may exist publication bias. Dengzhanxixin injection on the basis of conventional treatment can improve the efficacy of the treatment of unstable angina pectoris. However, due to the sample size of included studies were small and of lower quality, conclusions above still need high-qualitied randomized, double-blind, controlled trials be confirmed.

    Multislice computed tomography (MSCT) coronary angiography (CAG) is a noninvasive technique with a reported high diagnostic accuracy for coronary artery disease (CAD). Women, more frequently than men, are known to develop atypical angina symptoms. The purpose of this study was to investigate whether the diagnostic accuracy of MSCT in women with atypical presentation differs from that in men. We enrolled 396 in-hospital patients (141 women and 255 men) with suspected or proven CAD who successively underwent both MSCT and invasive CAG. CAD was defined as any coronary stenosis of ≥50% on conventional invasive CAG, which was used as the reference standard. The patients were divided into typical and atypical groups based on their symptoms of angina pectoris. The diagnostic accuracy of MSCT, including its sensitivity, specificity, negative predictive value, and positive predictive value (PPV), was calculated to determine the usefulness of MSCT in assessing stenoses. The diagnostic performance of MSCT was also assessed by constructing receiver operating characteristic (ROC) curves. The PPV (91% vs. 97%, χ2 = 5.705, P accuracy (87% vs. 93%, χ2 = 5.093,Pwomen than in men. Atypical presentation was an independent influencing factor on the diagnostic accuracy of MSCT in women (odds ratio = 4.94, 95% confidence intervals: 1.16-20.92, Walds = 4.69, P women with typical angina pectoris had higher PPV (98% vs. 74%, χ2 = 17.283.

    We performed exercise thallium-201 myocardial scintigraphy in 32 patients with angina pectoris to study the incidence of perfusion defects, who had no significant organic stenosis on coronary angiography. 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{sub 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).

    Reverse redistribution and rapid washout of 99m Tc-sestamibi are observed in patients with acute myocardial infarction and may indicate viable myocardium. However, the clinical significance of this phenomenon has not been rigorously examined in other cardiac diseases. Thus, we investigated whether reverse redistribution and washout of 99m Tc-sestamibi could be used in the diagnosis and follow-up of patients with coronary spastic angina. Thirty patients diagnosed as coronary spastic angina were examined. During coronary arteriography, spasm was induced by provocation test with ergonovine, and only total or subtotal occlusion was considered positive. Myocardial perfusion tomography was obtained 45 min (early) and 3 hr (delayed) after 99m Tc-sestamibi injection. Segmental defect score was visually graded from 0 (normal) to 4 (defect), and a total defect score was determined as the sum of defect scores for all segments. Washout rate of 99m Tc-sestamibi from the myocardium was calculated for each segment. After medical treatment with calcium antagonists and nitrates for 3 months, 99m Tc-sestamibi imaging was repeated. Out of 30 patients, on the early images 17 (57%) patients demonstrated decreased 99m Tc-sestamibi uptake in spastic segments; on the other hand, 24 (80%) patients did decreased 99m Tc-sestamibi uptake in spastic segments on delayed images. Total defect scores in delayed images were higher than those in early images (6.9±0.3 vs. 3.6±0.4, p 99m Tc-sestamibi was observed in 17 out of 30 patients (57%) with coronary spastic angina. Washout rate of 99m Tc-sestamibi from spastic segments was higher than that from non-spastic segments (16±2% vs. 11±5%, p 99m Tc-sestamibi was observed in patients with coronary spastic angina and might indicate that the ability of myocyte to retain the tracer was impaired due to repetitive brief ischemia by coronary spasm. The early and delayed 99m Tc-sestamibi imaging provides useful information for the diagnosis and responses

    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.

    Prevalence rates of coronary artery disease are reported to be very high in Asian Indians. Traditional risk factors alone fail to explain the high rates of coronary artery disease in Indians. Acute phase reactants C-reactive protein and C3 in Indian subjects with unstable angina were evaluated and compared them with suitable controls to test the hypothesis that a relationship exists between acute phase reactants and unstable angina. Forty cases of unstable angina and forty suitable controls were enrolled for the study. Cases of unstable angina had significantly increased level of CRP as compared to control group (p = 0.01098). Statistically significant difference was found between case and control groups in TLC (p = 0.0037) and ESR (p = 0.0368), TLC and ESR being more in case group as compared to control group. C-reactive protein was significantly correlated with TLC, ESR and C3 in case group and TLC and ESR in control group. C3 was significantly correlated with all the other three inflammatory markers. C-reactive protein, TLC and ESR in case group while no correlation was observed with any variable in control group. The present study concludes that a relationship exists between acute phase reactants studied and unstable angina.

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.

    The aim of our study was to investigate the relationship between coronary artery disease (CAD), angina, and clinical outcomes in patients with heart failure and preserved ejection fraction enrolled in the irbesartan in patients with heart failure and preserved systolic function (I-Preserve) trial. The mean follow-up period for the 4128 patients enrolled in I-Preserve was 49.5 months. Patients were divided into 4 mutually exclusive groups according to history of CAD and angina: patients with no history of CAD or angina (n=2008), patients with no history of CAD but a history of angina (n=649), patients with a history of CAD but no angina (n=468), and patients with a history of CAD and angina (n=1003); patients with no known CAD or angina were the reference group. After adjustment for other prognostic variables using Cox proportional-hazard models, patients with CAD but no angina were found to be at higher risk of all-cause mortality (hazard ratio [HR], 1.58 [1.22-2.04]; P<0.01) and sudden death (HR, 2.12 [1.33-3.39]; P<0.01), compared with patients with no CAD or angina. Patients with CAD and angina were also at higher risk of all-cause mortality (HR, 1.29 [1.05-1.59]; P=0.02) and sudden death (HR, 1.83 [1.24-2.69]; P<0.01) compared with the same reference group and had the highest risk of unstable angina or myocardial infarction (HR, 5.84 [3.43-9.95]; P<0.01). Patients with heart failure and preserved ejection fraction and CAD are at higher risk of all-cause mortality and sudden death when compared with those without CAD.

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.

    To observe the effect of Yiqi Yangyin Decoction (, YQYYD) on the quality of life (QOL) of patients with unstable angina pectoris (UAP). A total of 108 patients with UAP of qi-yin deficiency syndrome confirmed by coronary angiography were enrolled and assigned to the treated group (treated with YQYYD and conventional therapy of Western medicine) and the control group (treated with conventional therapy of Western medicine), by the use of the PROC PLAN of the SAS 6.12 software, in a prospective, randomized, controlled design. The clinical total effective rate, symptom score, QOL scale [Seattle Angina Questionnaire (SAQ)] and incidence of important clinical events were defined as the observation indices to evaluate the interventional effect of YQYYD on the QOL of patients with UAP of the qi-yin deficiency syndrome. During the study, three cases dropped out in the treated group, one case dropped out in the control group, and 104 cases, including 51 cases in the treatment group and 53 cases in the control group, finished the trial. After four weeks of treatment, the total clinical effective rates in the treated group and the control group were 80.4% and 75.5% respectively, and there was no obvious difference between them (P>0.05). However, the symptom score of the treated group (9.31 + or - 2.02) was significantly lesser than that of the control group (11.62 + or - 3.04, Pangina stability, angina frequency, and treatment satisfaction were significantly ameliorated when compared with the control group after treatment (P0.05). YQYYD could improve the clinical symptoms of patients with UAP of qi-yin deficiency syndrome and greatly improve their QOL.

    Full Text Available O autor traz à consideração clínica a "facilitação" que Sherrington apreciou nos experimentos de neurofisiologia, e que explica aspectos clínicos importantíssimos em psicologia e em neurologia visceral. Pretende o autor explicar seus casos de dor (um de causalgia no membro superior e três de angina de peito em portadores de esclerose coronária. Ora a anestesia terapêutica no gânglio estrelado, ora na cadeia ganglionar torácica simpática, ora a radioterapia, ora a psicoterapia removeram a dor "facilitada" a tal ponto que se tornara "dominante", isto é, mesmo estímulos inadequados a provocavam. Os doentes eram inválidos e recuperaram-se. A neurofisiologia moderna autoriza a interpretação dessa terapêutica: suprimiu-se - com a anestesia, com a radioterapia e com a psicoterapia - o circuito neural auto-alimentado reverberante, hiperfuncionante em todo ou em parte de seu trajeto, quer aferente ao córtex quer aferente às coronárias. O autor discute o valor clínico dos acessos anginosos apontando fatos que documentam que o acesso "ilegítimo" (psicógeno deve ter como causa a estimulação das aferências vegetativas ao córtex em qualquer ponto (ganglionar, medular ou cortical. Os acessos "legítimos", produzindo lesões transitórias ou definitivas e até morte,, devem ser explicados pela atividade das eferências vagais que executam os efetôres espásticos das coronárias. A dor é apresentada como fenômeno de "gravação neural", aprendido, memorizado e automatizado, ativado em feed-back ora nas aferências vegetativas ao córtex, ora nas eferências, mais perigosas e mortais. Debate-se a superestimada psicogenia da angina de peito.

    It is shown for the first time that changes of self-actualization (SA) in patients with CHD are the main risk factor of myocardial infarction (MI) and unstable angina (UA). The clinical course and prognosis of MI correlate with SA prior to the development of an acute coronary event. Isolated correlations exist between CHD risk factors and results of SA questionnaire studies. SA personality peculiarities in patients with MI and UA account for more than 50% dispersion of the results of linear factor analysis.

    Full Text Available A 60-year-old man presented with typical angina and had a positive stress test. He declined both drug therapy and invasive testing. Instead, he chose to adopt a whole-food plant-based diet, which consisted primarily of vegetables, fruits, whole grains, potatoes, beans, legumes, and nuts. His symptoms improved rapidly, as well as his weight, blood pressure, and cholesterol levels. Plant-based diets have been associated with improved plasma lipids, diabetes control, coronary artery disease and with a reduction in mortality. Adoption of this form of lifestyle therapy should be among the first recommendations for patients with atherosclerosis.

    Ludwig's angina is a rapidly spreading cellulitis that may produce upper airway obstruction often leading to death. The present paper reviews the management of Ludwig's angina in the third trimester of pregnancy. The inherent dangers to the mother and her unborn child are highlighted. The case files of pregnant patients who had emergent incision and drainage for life-threatening facial cellulitis at the maxillofacial unit of the Murtala Mohammed Specialist Hospital in Kano, Nigeria, over a 2 year period were retrieved and demographic and clinical characteristics were retrospectively obtained and analyzed descriptively using the statistical package for social sciences (SPSS version 13.0, for Windows, September 2004, Chicago, Illinois). Comparative statistics were determined using Pearson's Chi-square, Fisher's exact tests and independent t tests as appropriate. A P value of less than 0.05 was considered significant. A total of 10 patients were seen within the study period, age ranges from 23 to 40 years, mean 29.5 (5.3) years. Majority of the women were in their third decade [60% (6/10)] while the remaining 40% (4/10) were in their fourth decade of life. Two of the patients presented within the period of less than 1 week of onset of symptoms while those who presented within the periods of 1-2 weeks and periods of over 2 weeks accounted for 50% (5/10) and 30% (3/10) respectively. All the patients presented during the third trimester of their pregnancy and odontogenic infections were responsible for 80% (8/10) of the Ludwig's angina. There were 20% mortality among the patients and this was significant for those with underlying systemic conditions (P = 0.02). The time of presentation was not significant for the survival rate of the gravid patient (P = 0.36) but was significant for survival of the fetus (P = 0.01). During a life-threatening infectious situation such as Ludwig's angina, risks of maternal and fetal morbidity include both septicemia and asphyxia. Attending

    The purpose of this study is to determine the diagnostic accuracy for detection of culprit lesions in patients with unstable angina. Both ATP {sup 201}Tl SPECT and coronary angiography were performed in 51 patients with unstable angina pectoris within a week since the last attack. SPECT images were divided into 17 segments and the regional uptakes were scored semiquantitatively (0=normal to 3=no activity) and compared with the coronary angiographic findings. ATP {sup 201}Tl SPECT revealed decreased uptakes in 54 of 56 culprit lesions. The sensitivity, specificity and accuracy for detection of culprit lesions were 96.4%, 89.5% and 92.4%, respectively. Although adverse effects during ATP administration were complicated in 28 (54.9%) patients, all the complications were mild and resolved within two minutes. ATP {sup 201}Tl SPECT is sensitive and reliable method for detecting culprit lesions and can be performed safely even at acute phase in patients with unstable angina pectoris. (author)

    2013-01-01

    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. PMID:24826293

    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.

Se evaluó: calidad de vida, utilizando la escala de WOMAC reducida convertida a una escala del 1 al 100, recuperación funcional en función del tiempo en que se logró la bipedestación, necesidad de ortesis al final del seguimiento, y el regreso a las tareas de la vida diaria utilizando la sub-escala de función de la Sociedad Americana de Tumores Musculoesqueléticos. Resultados A los 14 meses el promedio de WOMAC total fue 77. El 73 % de la población caminó dentro de las 36 hs de la cirugía. El 48% retornó a las actividades diarias con una restricción mínima, el resto tuvo restricciones recreacionales y parciales. El 71% del grupo que no utilizaba ortesis conservó tal condición al finalizar el seguimiento. La incidencia de complicaciones intraoperatorias y postoperatoria fue 6,5% y 23%. La fractura distal al clavo y el “cut-out” se produjeron solo en el 1%. Discusión La baja incidencia de “cut-out” y fractura distal al clavo con la posibilidad de inserción temprana a las actividades, conservando una buena calidad de vida y función, convierten al ITST en un alternativa de elección para el tratamiento de las fracturas intertrocantéricas inestables de cadera.

    In an aging western population, a significant number of patients continue to suffer from angina once all revascularization and optimal medical treatment options are exhausted. Under experimental conditions, oral supplementation with inorganic nitrate was shown to exhibit a blood pressure-lowering effect, and has also been shown to promote angiogenesis, improve endothelial dysfunction and mitochondrial efficiency in skeletal muscle. It is unknown whether similar changes occur in cardiac muscle. In the current study, we investigate whether oral sodium nitrate treatment will improve myocardial ischemia in patients with stable angina.

    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)

    1993-02-01

    The article studies the average angina morbidity in the military unit during 9 years which resulted in 48.4% (scarlet fever--0.34%). Laboratory diagnostics is needed to make the estimation of streptococcal infection which has an acute respiratory infectious character during its clinical course. Among the whole number of patients 89.2% have come through this illness for one time, 9% twice, and 4.8%--three times. The dynamics of the angina morbidity had a periodical cycle of 2-3 years which was independent from the morbidity cycle of local civilian population. The authors show a statistic dependency between average morbidity index and the quantity of servicemen in one dormitory, its square and volume per one man. Application of "time before illness" index for 24 months made it possible to disclose the phase character in the development of streptococcal infection among personnel of the same call-up period. The general tendency towards reduction of the morbidity index was accompanied with regular upgrades of the infection after each spring or autumn renovation of personnel.

    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.

  14. Effect of oral aminophylline in patients with angina and normal coronary arteriograms (cardiac syndrome X).

    Elliott, P. M.; Krzyzowska-Dickinson, K.; Calvino, R.; Hann, C.; Kaski, J. C.

    1997-01-01

    BACKGROUND: Patients with syndrome X (exertional angina, positive exercise test, normal coronary arteriogram) have an altered perception of cardiac pain. This symptom may arise from increased sensitivity to adenosine. Previous studies suggest that intravenous aminophylline (an adenosine receptor blocker) improves exercise tolerance in patients with this disorder. OBJECTIVE: To examine the efficacy of oral aminophylline in syndrome X. METHODS: 13 patients (11 women and two men, mean (SD) 54 (6) years) with syndrome X were studied. Patients were randomised in a double blind crossover study to receive either oral aminophylline or placebo for three weeks. All patients underwent symptom limited exercise testing and ambulatory electrocardiography at the end of each three week period. RESULTS: 10 patients completed the study. The time to angina during exercise testing in patients who were given aminophylline was longer than for the placebo group (mean (SD) 632 (202) seconds v 522 (264) seconds, P = 0.004). Peak exercise ST depression did not differ significantly between patients who received aminophylline and those administered placebo (mean (SD) -1.9 (0.7) mm v -1.5 (0.8) mm). Six patients taking aminophylline reported a reduction in the total number of episodes of chest pain during the three weeks, but the frequency and duration of ST segment depression during Holter monitoring was unchanged. CONCLUSION: Oral aminophylline has a favourable effect on exercise induced chest pain threshold in patients with syndrome X. The disparate effects on symptoms and ST segment changes are intriguing and further study is warranted. PMID:9227295

    Full Text Available This study evaluated whether statin therapy changed a diagnostic validity of lipid and inflammatory markers in ischemic heart disease (IHD patients. Levels of lipids, lipoproteins, apolipoproteins, inflammatory markers, and atherogenic indexes were determined in 49 apparently healthy men and women, 82 patients having stable angina pectoris (SAP, 80 patients with unstable angina (USAP, and 106 patients with acute ST-elevation myocardial infarction (STEMI treated or not treated with statins. Diagnostic accuracy of markers was determined by ROC curve analysis. Significantly lower apoA-I in all statin-treated groups and significantly higher apoB in statin-treated STEMI group compared to non-statin-treated groups were observed. CRP showed the best ROC characteristics in the assessment of STEMI patients. Lp(a is better in the evaluation of SAP and USAP patients, considering that Lp(a showed the highest area under the curve (AUC. Regarding atherogenic indexes, the highest AUC in SAP group was obtained for TG/apoB and in USAP and STEMI patients for TG/HDL-c. Statins lowered total cholesterol, LDL-c, and TG but fail to normalize apoA-I in patients with IHD.

  16. O MAPA COMO RELATO

    Full Text Available Este ensaio propõe uma reflexão crítica sobre o mapa como modelo privilegiado de representação do espaço. Partindo da iconografia historicamente verificada com a disseminação do imaginário do globo terrestre e buscando os possíveis estratos heterotópicos ou margens de desobediência cartográfica atuantes nos mapas existentes bem como na emergência de novos mapas, aborda algumas das suas transformações históricas na tensão constantemente experimentada entre inventário e invenção, através de um conjunto selecionado de reflexões e proposições de autores vindos não da geografia mas das artes visuais e da literatura tais como Joaquín Torres-García, Georges Perec, Joan Brossa, Julio Cortázar e outros. Frente à análise da aplicabilidade do mapa como relato subjetivo e da sua aproximação com uma experiência cartográfica múltipla e diversa capaz de inventariar, nos lugares estudados, a qualidade poética da vida, o mapa ressurge, assim, como ciência das qualidades em detrimento de campo das quantidades. Propõe-se, conclusivamente, repensar a cartografia como uma plataforma científica que, mesmo nas suas origens, já guardava uma potência mítica para relatos abertos e transversais à ciência e que, no contexto atual, pode tornar-se uma plataforma de ação criativa em prol de novas sensibilidades perceptivas, novos mundos estéticos e novos movimentos prospectivos de transformação imaginativa do espaço, ampliando e complexificando o esforço de conhecer as nossas relações geográficas.

    Angina often persists or returns in populations following percutaneous coronary intervention (PCI). We hypothesized that ranolazine would be effective in reducing angina and improving quality of life (QOL) in incomplete revascularization (ICR) post-PCI patients. In RIVER-PCI, 2604 patients with a history of chronic angina who had ICR post-PCI were randomized 1:1 to oral ranolazine versus placebo; QOL analyses included 2389 randomized subjects. Angina and QOL questionnaires were collected at baseline and months 1, 6, and 12. Ranolazine patients were more likely than placebo to discontinue study drug by month 6 (20.4% versus 14.1%, Pdiabetics (mean difference 3.3; 95% CI 0.6, 6.1; P=0.02) and those with more angina (baseline SAQ angina frequency ≤60; mean difference 3.4; 95% CI 0.6, 6.2; P=0.02), but was not maintained at month 12. Despite ICR following PCI, there was no incremental benefit in angina or QOL measures by adding ranolazine in this angiographically-identified population. These measures markedly improved within 1 month of PCI and persisted up to 1 year in both treatment arms. URL: http://www.clinicaltrials.gov.

    Twelve patients with stable angina and 12 patients with unstable angina underwent rest iodine-123-{beta}-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)

    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

    Experimental studies demonstrate that granulocyte colony stimulating factor (G-CSF) promotes neovascularisation and confers cardioprotection. To assess the efficacy of repeated low dose G-CSF plus exercise on myocardial ischaemia in patients with severe chronic ischaemic heart disease. 18 patients with Canadian Cardiovascular Society class III-IV angina completed a randomised, double blind, crossover study of dose adjusted G-CSF versus placebo. Exercise was commenced 6 weeks prior and continued for the duration of the study. G-CSF or placebo was administered daily for 5 consecutive days at fortnightly intervals for three cycles, followed by crossover after 6 weeks. Primary outcome was myocardial perfusion by cardiac magnetic resonance imaging (MRI). Secondary outcomes were: Seattle Angina and Utility Based Quality of Life Heart Questionnaire (SAQ/UBQ-H), Exercise Stress Test (EST) and quantification of endothelial progenitor cells (EPC) by flow cytometry and angiogenic cytokines by immunoassay. Compared with placebo, G-CSF had no effect on myocardial ischaemia by cardiac MRI, EST or SAQ/UBQ-H, despite effective EPC mobilisation (peak fold increase: CD34+ =19, CD34+ CD133+ = 37, CD34+ vascular endothelial growth factor receptor 2 (VEGFR-2)+ = 5, CD34+ CD133+ VEGFR-2+ = 3; all p<0.05 vs. placebo). Plasma levels of stromal cell derived factor 1, angiopoietin 1, interleukin 8 and tumour necrosis factor α decreased after a symptom limited EST while vascular endothelial growth factor and platelet derived growth factor remained unchanged. All cytokines were unchanged following G-CSF. Seven troponin I positive events occurred with G-CSF compared with three with placebo (p=0.289). High sensitivity C reactive protein and N terminal prohormone brain natriuretic peptide increased with G-CSF (both p<0.01 vs. placebo). In patients with chronic ischaemic heart disease, G-CSF mobilises EPCs but does not improve myocardial perfusion or angina. G-CSF increases plasma levels of

    In this study, we aimed to investigate the impact of prophylactic intracoronary adenosine administered during percutaneous coronary intervention (PCI) due to unstable angina pectoris on myonecrosis by measuring post-procedural levels of cardiac troponin I (cTnI) and creatine kinase-myocardial band (CK-MB). A total of 122 patients with unstable angina undergoing PCI were included in this single-center, double-blind, randomized study. The patients were randomly allocated to adenosine and placebo groups. In the adenosine group, a single-dose of intracoronary adenosine (100 μg for the right coronary artery and 150 μg for the left coronary artery) was administered. Primary endpoint was post-PCI myonecrosis, which was defined as abnormal levels of periprocedural cTnI. Secondary endpoints were defined as elevated cTnI levels [5 × upper limit of normal (ULN)], abnormal CK-MB levels, angiographic coronary flow measured by Thrombolysis In Myocardial Infarction (TIMI) frame count (TFC), the cumulative incidence of in-hospital death and in-hospital urgent target vessel revascularization (TVR). Clinical and angiographic characteristics of both adenosine (61 patients, 61 ± 9 years) and placebo (61 patients, 59 ± 10 years) groups were similar (p > 0.05 for all). Post-procedural abnormal cTnI levels in the adenosine group were significantly lower than the placebo group (32 % vs. 55 %, p: 0.011). cTnI >5 × ULN (21 % vs. 31 %, p: 0.217) and abnormal CK-MB levels (11 % vs. 19 %, p: 0.263) were similar in both groups. Post-procedural TFCs in the adenosine group were significantly lower than the placebo group (24 ± 4 vs. 27 ± 5, p: 0.004). In-hospital events including death and urgent TVR were not observed in either group. Intracoronary administration of single-dose adenosine in patients with unstable angina undergoing PCI is associated with decreased periprocedural myonecrosis and improved coronary blood flow.

    Microvascular angina (MVA) is an incompletely understood clinical entity. Computational analysis of coronary Computed Tomography Angiography (CTA) has shown an association between low coronary lumen volume to myocardial mass (V/M) ratio and lower Fractional Flow Reserve values, independent of plaque measures. We hypothesized that low V/M ratio may be present in patients with MVA. A retrospective case-control analysis was performed using patients fulfilling guideline criteria for MVA with controls matched for age, gender, coronary risk factors and atherosclerotic plaque burden. V/M was extracted off site (Heartflow Inc; Redwood City, CA) employing allometric scaling laws that allow the definition of the coronary circulation beyond the epicardium. FFR CT values were calculated in the major epicardial coronary arteries for each group. A total of 30 patients with MVA and 32 matched controls were included in the study. Mean total coronary lumen volume (2302 mm 3  ± 109 vs 2978 mm 3  ± 134, p < 0.001) and mean myocardial mass (90.4 g ± 13.7 vs 100.4 g ± 20.1, p = 0.029) were lower in MVA patients compared to controls. Mean V/M ratio was significantly lower in MVA compared to controls (25.6 mm 3 /g ± 5.9 vs 30.0 mm 3 /g ± 6.5, p = 0.007; c-statistic 0.69). V/M ratio did not differ significantly between subclasses of angina severity (p = 0.747). No difference in mean nadir FFR CT values was found between MVA and control groups in the LAD (0.86 ± 0.07 vs 0.83 ± 0.07, p = 0.154), LCX (0.90 ± 0.05 vs 0.90 ± 0.06, p = 0.240) and RCA (0.90 ± 0.04 vs 0.90 ± 0.03, p = 0.773) vessels. Patients with microvascular angina demonstrate a significantly lower coronary CTA-derived coronary volume/myocardial mass ratio than asymptomatic controls.

    Full Text Available As informações sobre alimentação estão mais acessíveis e democráticas. As tendências alimentares são inspiradas por diversos fatores, mas sempre estão associados à moda, mídia e como forma de conjectura de um estilo de vida. Há pouco tempo, as grandes cidades brasileiras foram invadidas por uma nova mania: as paletas mexicanas, que, na verdade, não são “tão mexicanas”. Esses sorvetes apresentam qualidades organolépticas marcantes, em virtude, entre outros fatores, ao alto teor de açúcar e, em alguns casos, de gorduras. A concepção gourmetizada e natural dessa iguaria, seu custo e as propriedades nutricionais são peculiares e, aparentemente, um modismo. Esse trabalho teve como objetivo conhecer a composição desses produtos, a partir das informações nutricionais contidas nos sites das empresas produtoras, bem como as suas peculiaridades e concepções. Apesar da conotação natural e gastronômica, alto valor calórico, gorduras (especialmente na versão recheada sabor brigadeiro e elevadas quantidades de açúcares, foram encontrados, em média, por unidade: 207,2 Kcal; 38,4g de carboidratos; 3,9g de proteínas e 5,3g de gorduras.

    To evaluate the efficiency of 6-month therapy with xenical (gastrointestinal lipase inhibitor) in combination with diet in patients with stable angina pectoris associated with obesity and hyperlipemia. An open comparative randomized study of the efficiency of xenical in combination with diet was carried out in patients with stable angina pectoris concomitant with obesity and hyperlipemia. Thirty coronary patients aged 45-65 years with stable angina of effort (functional class I-II) with body weight index 28.1-45.6 kg/m2 (mean 33.5 kg/m2) were examined. All patients presented with dyslipemia (low density lipoprotein (LDL) cholesterol more than 4.14 mmol/liter, triglycerides (TG) more than 2.2 mmol/liter). Controls (n = 15) were treated with diets alone for 6 months. In the main group diets were supplemented by xenical in a dose of 360 mg/day. Body weight index decreased in both groups (by 9.9% in the main group and by 4.2% in the control). Body weight stabilization during 6 months of treatment and the fact that it was slow and gradual were essential. In patients treated with xenical total cholesterol level decreased by 10.9% and of LDL cholesterol by 12.2% after 6 months (p < 0.05). Changes in the levels of high density lipoprotein cholesterol and TG were insignificant. The drug did not affect the incidence of angina attacks and improved exercise tolerance after 6-month therapy. Blood biochemistry (transaminases, alkaline phosphatase, glucose, and creatinine) changed negligibly. No side effects were observed; all patients received a complete 6-month course. The results confirm that xenical (orlistat) can be used for long therapy of patients with stable angina of effort concomitant with obesity and hyperlipemia.

  20. Paradoxical effect of smoking in the Spanish population with acute myocardial infarction or unstable angina: results of the ARIAM Register.

    The paradoxical effect of smoking after acute myocardial infarction (AMI) is a phenomenon consisting of a reduction in the mortality of smokers compared to nonsmokers. However, it is not known whether the benefit of this reduction in mortality is due to smoking itself or to other covariables. Despite acceptance of the paradoxical effect of smoking in AMI, it is not known whether a similar phenomenon occurs in unstable angina. The objective of this study was to investigate the paradoxical effect of smoking in AMI and unstable angina, and to study specifically whether smoking is an independent prognostic variable. The study population was selected from the multicentric ARIAM (Análisis del Retraso en el Infarto Agudo de Miocardio [analysis of delay in AMI]) Register, a register of 29,532 patients with a diagnosis of unstable angina or AMI. Tobacco smokers were younger, presented fewer cardiovascular risk factors such as diabetes or hypertension, fewer previous infarcts, a lower Killip and Kimball class, and a lower crude and adjusted mortality in AMI (odds ratio, 0.774; 95% confidence interval, 0.660 to 0.909; p = 0.002). Smokers with unstable angina were younger, with less hypertension or diabetes. In the multivariate analysis, no statistically significant difference in mortality was found. The reduced mortality observed in smokers with AMI during their stay in the ICU cannot be explained solely by clinical covariables such as age, sex, other cardiovascular factors, Killip and Kimball class, or treatment received. Therefore, smoking may have a direct beneficial effect on reduced mortality in the AMI population. The lower mortality rates found in smokers with unstable angina are not supported by the multivariate analysis. In this case, the difference in mortality can be explained by the other covariables.

    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.

    The aim of this study was to investigate whether the Japan Arteriosclerosis Longitudinal Study (JALS) score, which is calculated from the traditional atherosclerotic coronary risk, is associated with the incidence of coronary vasospasms. We performed vasospasm provocation tests with acetylcholine in 109 patients referred to our hospital due to suspected vasospastic angina and subsequently calculated the atherosclerotic risk score according to the JALS score. Consequently, coronary vasospasms were evoked in 51 patients. The patients were divided into three groups according to the tertile of the JALS score: 1st, 42, n=37. The third tertile exhibited the greatest risk for vasospasms. A multivariate logistic regression analysis revealed that the JALS score (odds ratio: 1.686, pJALS score can serve as a useful tool for evaluating patients with suspected coronary vasospasms.

    Ninety cases of angina pectoris patients with the Deficiency of Heart Qi Syndrome (DHQS), Deficiency of Heart-Yin Syndrome (DHYS) and blood stasis in Heart vessels Syndrome (BSHVS) were studied. The number of patients were 30 for each group. Their regulatory polypeptides:atrial natri-uretic polypeptide (ANP), beta-Endorphine (beta-EP), Endothelin (ET), Angiotensin (A-II) were tested. Results showed that in comparing with normal level, P BSHVS > normal group > DHYS. ET and A-II of them: DHYS > BSHVS > normal group > DHQS. And the comparison between groups revealed that P < 0.05 or < 0.01. So ANP, beta-EP, ET and A-II were the principal material basis, and they could be the specific objective parameters of the Syndrome Differentiation.

    This study aimed to explore the related metabolic biomarkers and to observe the effects of Yangxin Decoction (YXD) on plasma metabolism of patients with unstable angina (UA). In total, 10 patients with UA (intervention group) and 10 healthy participants (control group) were recruited for this study from January 2009 to December 2010. Plasma samples from both groups were analyzed using liquid chromatography mass spectrometry (LC-MS). Principle component analysis (PCA) and partial least squares (PLS) were used to explore the correlations between metabolic markers in patients with UA. The LC-MS results indicated that the serum levels of 5 potential metabolic markers, namely, ceramide, glycocholic acid, allocholic acid, lithocholic acid, and leukotriene (LT) B4, were significantly higher in the intervention group than those in the control group. The results of this study demonstrated potential metabolic markers that can be used to distinguish and diagnose patients with UA.

    The origin of hemorheologic and endothelial defects in patients with unstable angina (comparing with healthy persons) is determined by a solar activity period: the blood viscosity increases in a period of high solar activity in the vessels of small, medium and macro diameters, a local decompensate dysfunction of small vessels endothelium had been fixed (microcirculation area). In the period of a low solar activity there is an increase of a blood viscosity in vessels of all diameters, generalized subcompensated endothelial dysfunction is developed (on the background of the III phase blood clotting activating). In the period of a high solar activity a higher blood viscosity had been fixed, comparing with the period of a low solar activity.

    ABO blood groups are genetically transmitted through chromosome 9 at locus 9q34. It is supposed that there is a locus on 9p21, which has a role in developing coronary artery disease. Our study population consisted of 309 patients with unstable angina admitted to the Ziaeian Hospital, Tehran, Iran, who underwent coronary angiography. The association between types of blood group (O and non-O) with the severity of coronary artery disease was investigated. Compared to the non-O groups, the O group had more severe coronary artery involvement (P = 0.004). Our study supports recent suggestions on the association between blood group and coronary artery disease. Further studies are needed to evaluate the effect of blood group on atherosclerosis.

    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)

    Ludwig's angina is a deep neck space infection. Unlike other abscesses elsewhere in the body, rapid progression of the disease results in serious complications such as airway oedema, distortion, total obstruction with loss of airway and death. Thus, early diagnosis and skilful airway management is necessary. For safe airway management, fibreoptic intubation or tracheostomy under local anaesthesia is recommended.1 We describe a case report where an initial attempt at fibreoptic intubation failed and subsequently bleeding ensued causing difficulty in viewing the larynx by fibreoptic bronchoscopy. Radiological investigations such as ultrasound and computer tomography (CT) are commonly ordered by surgeons and emergency physicians to know the extension of disease, but airways and larynx are seldom included. We discuss the role of ultrasound in airway assessment in such critical cases to ensure safe and uncomplicated airway access.

    To systematically evaluate the clinical effectiveness and safety of Danshen Injection (, DS) as one adjuvant treatment for conventional therapy with Western medicine (WM) for unstable angina pectoris (UAP). Using literature databases, a thorough and systematic retrieval of randomized controlled trials (RCTs) comparing DS plus WM with WM was conducted from inception to April 2015. The extracted data from included studies was analyzed by Review Manager 5.2 software. The Cochrane risk of bias tool was used to assess the quality of included studies, and Begg's and Egger's tests conducted by Stata 12.0 were used to evaluate the potential presence of publication bias. A total of 17 RCTs, which involving 1,433 participants, were identified and reviewed. The meta-analysis indicated that the combined use of DS and WM was significantly superior to WM alone for UAP in terms of the total effectiveness rate of angina pectoris [risk ratio (RR) =1.23, 95% confidence interval (CI): 1.17, 1.29, P<0.01] and the total effectiveness rate of electrocardiogram (ECG) [RR=1.18, 95%CI: 1.06, 1.30, P=0.001]. Additionally, DS could also further reduce the content of fibrinogen, adjust blood lipid level, correct T wave inversion, and so on. Fifteen adverse drug reactions were reported in two studies, Four of which appeared in the experimental group. Based on the systematic review, the combined use of DS and WM was more effective than WM alone, it can be further widely used in clinic, however, there was no exact conclusion for its safety.

    Vaspin was a recently identified adipokine, playing a protective role in many metabolic diseases. The present study aimed to investigate the association between vaspin plasma level and stable angina pectoris (SAP) and unstable angina pectoris (UAP). A total of 88 patients with angiographically-proved coronary artery disease (CAD) (SAP 47, UAP 41) and 103 control subjects without cardiovascular diseases were enrolled in this study. Circulating vaspin, mRNA expression of vaspin in peripheral blood mononuclear cells (PBMC), clinical parameters, lipid profile and high-sensitivity C-reactive protein (hsCRP) were assayed. The severity of CAD was also assessed according to the number of vessels diseased. There are significant differences in circulating vaspin levels and mRNA levels of PBMC between SAP and UAP groups (SAP 0.91±0.95 ng/mL and UAP 0.43±0.38 ng/mL, p<0.01 in circulating vaspin level; SAP 1.19±0.85 and UAP 0.82±0.56, p<0.05 in mRNA level of PBMC). An inverse correlation between the number of diseased vessels and plasma vaspin concentration was observed (r=-0.350, p<0.01) in the CAD group. Construction of receiver operating characteristic curves confirmed that vaspin plasma concentrations significantly differentiated CAD patients (area under the curve=0.684, p<0.001), as well as UAP (area under the curve=0.640, p<0.05). Decreased vaspin plasma levels and mRNA levels in PBMC were observed in patients with UAP. Low vaspin concentrations correlate with CAD severity. The findings suggested that vaspin could serve as a novel biomarker of CAD as well as UAP.

    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

    Intravascular ultrasound (IVUS) enables the identification of calcification with more details and quantification of calcification, but there is not a proper method to quantify the calcification with IVUS. Previous IVUS studies used arc or length of calcium, respectively, to quantify calcification, but calcium is determined by a combination of arc and length. We devised a new method to quantify calcium as arc area (AA) in the present study, and AA is two-dimensional and irrelevant to vessel size. We selected 201 patients with stable angina pectoris (SAP), unstable angina pectoris (UAP), or acute myocardial infarction (AMI) who underwent IVUS imaging of a de novo native atherosclerotic lesion considered to be the culprit lesion before percutaneous coronary intervention between December 2001 and December 2007. The culprit lesion site for analysis was the 10 mm-long segment including the smallest lumen cross-sectional area. The arc of each calcium deposit in each image was measured with a protractor centered on the lumen and the length of each calcium deposit was calculated with the number of images containing the calcium deposit minus 1, then multiplying 0.5 mm (the images were 0.5 mm apart). Finally, the AA was calculated by arc (degree) multiplying length (mm). The average number of calcium deposits in the culprit lesions of patients with acute myocardial infarction (AMI) was significantly larger than patients with SAP or UAP, and the number of calcium deposits of patients with SAP or UAP was almost the same (mean +/- SD, AMI 2.21 +/- 1.98, SAP 1.15 +/- 1.01, UAP 1.20 +/- 1.15, AMI versus SAP or UAP; p < 0.0005). The average AA per calcium deposit was significantly different in culprit lesions of patients with SAP and UAP or AMI, the calcium deposits were bigger in SAP than in UAP or AMI, and there were no differences between UAP and AMI (mean +/- SD, SAP 788.6 +/- 767.0 degree x mm, UAP 136.6 +/- 189.3 degree x mm, AMI 148.4 +/- 217.1 degree x mm, SAP versus UAP or

    Full Text Available La presión social por constituir una forma indentitaria que sea acorde con el referente biológico es de origen histórico y se encuentra al servicio de prácticas de control y dominación social. Este artículo presenta una discusión sobre el lugar actual de la idea de identidad, especialmente en el plano de la sexualidad. Para esto recurre a la tesis de la filósofa Judith Butler, quien propone desde una visión deconstructivista y post-estructuralista una nueva definición de idenridad en términos de la iteración performativa. La identiclad es entendida entonces como una exigencia de inteligibiliclacl ante la sociedad, la cual limita las posibiliclades de expresión sexual.

    Full Text Available O artigo tenta demonstrar que todos os textos, mesmo aqueles cuja natureza é teórica, têm alguma forma de narrativa. Nem sempre são personagens que os ocupam, podem ser ideias, mas mesmo assim há um enredo conceitual que se passa. Modernamente, a forma dessa narrativa foi sobretudo o sistema, com a pretensão totalizadora presente, por exemplo, na filosofia de Hegel. Contemporaneamente, porém, a forma do ensaio – surgida ainda na era moderna – ganha destaque por sua forma descontínua de narrar. O objetivo do artigo é apontar que, se o ensaio é uma forma, como explicitaram Lukács, Benjamin e Adorno, ele é também uma forma de narrar – ainda que de narrar conceitualmente objetos da cultura.

    Personal digital assistants (PDAs) are popular with physicians: in 2003, 33% of Canadian doctors reported using them in their practices. We do not know, however, whether using a PDA changes the behaviour of practising physicians. We studied the effectiveness of a PDA software application to help family physicians diagnose angina among patients with chest pain. Prospective randomized controlled pilot trial using a cluster design. Primary care practices in the Toronto area. Eighteen family physicians belonging to the North Toronto Primary Care Research Network (Nortren) or recruited from a local hospital. We randomized physicians to receive a Palm PDA (which included the angina diagnosis software) or to continue conventional care. Physicians prospectively recorded the process of care for patients aged 30 to 75 presenting with suspected angina, over 7 months. Did the process of care for patients with suspected angina improve when their physicians had PDAs and software? The primary outcomes we looked at were frequency of cardiac stress test orders for suspected angina, and the appropriateness of referral for cardiac stress testing at presentation and for nuclear cardiology testing after cardiac stress testing. Secondary outcome was referrals to cardiologists. The software led to more overall use of cardiac stress testing (81% vs 50%). The absolute increase was 31% (P = .007, 95% confidence interval [CI] 8% to 58%). There was a trend toward more appropriate use of stress testing (48.6% with the PDA vs 28.6% control), an increase of 20% (P = .284, 95% CI -11.54% to 51.4%). There was also a trend toward more appropriate use of nuclear cardiology following cardiac stress testing (63.0% vs 45.5%), an absolute increase of 17.5% (P =.400, 95% CI -13.9% to 48.9%). Referrals to cardiologists did not increase (38.2% with the PDA vs 40.9%, P =.869). A PDA-based software application can lead to improved care for patients with suspected angina seen in family practices; this finding

    To estimate the cost-effectiveness of ranolazine when added to standard-of-care (SoC) antianginals compared with SoC alone in patients with stable coronary disease experiencing ≥3 attacks/week. An economic model utilising a UK health system perspective, a 1-month cycle-length and a 1-year time horizon. Patients with stable coronary disease experiencing ≥3 attacks/week starting in 1 of 4 angina frequency health states based on Seattle Angina Questionnaire Angina Frequency (SAQAF) scores (100=no; 61-99=monthly; 31-60=weekly; 0-30=daily angina). Ranolazine added to SoC or SoC alone. Patients were allowed to transition between SAQAF states (first cycle only) or death (any cycle) based on probabilities derived from the randomised, controlled Efficacy of Ranolazine in Chronic Angina trial and other studies. Patients not responding to ranolazine in month 1 (not improving ≥1 SAQAF health state) discontinued ranolazine and were assumed to behave like SoC patients. Costs (£2014) and quality-adjusted life-years (QALYs) for patients receiving and not receiving ranolazine. Ranolazine patients lived a mean of 0.701 QALYs at a cost of £5208. Those not receiving ranolazine lived 0.662 QALYs at a cost of £5318. The addition of ranolazine to SoC was therefore a dominant economic strategy. The incremental cost-effectiveness ratio was sensitive to ranolazine cost; exceeding £20,000/QALY when ranolazine's cost was >£203/month. Ranolazine remained a dominant strategy when indirect costs were included and mortality rates were assumed to increase with worsening severity of SAQAF health states. Monte Carlo simulation found ranolazine to be a dominant strategy in ∼71% of 10,000 iterations. Although UK-specific data on ranolazine's efficacy and safety are lacking, our analysis suggest ranolazine added to SoC in patients with weekly or daily angina is likely cost-effective from a UK health system perspective.

    Full Text Available El artículo de Emmanuel Housset implica un esfuerzo de rehabilitación del concepto «persona» para la filosofía contemporánea y la fenomenología. Para ello el autor busca mostrar cómo poco a poco «persona» tomó otra significación que la de «personaje» o sujeto de derecho. Es en autores como san Agustín y santo Tomás de Aquino que se halla un acceso diferente que pone el énfasis más bien en su carácter relacional y responsivo de la persona, antes que en su dimensión autónoma y autotélica. Tal dimensión aparece, según Housset, junto con la idea de persona como creatura y en oposición a la de individuo racional dueño de sí. La dimensión afectiva, la personalidad despertada por las diversas figuras de la alteridad son algunas de las dimensiones de la persona que examina el autor a partir del examen de la carne, las pasiones, la memoria, la historicidad y el amor alteridad.Emmanuel Housset's paper is an effort to revitalize the concept of 'person' for contemporary philosophy and phenomenology To this end the author looks to show how little by little the understanding of 'person' took on a different meaning to that of 'character' or "right bearing individual". It is in authors such as St. Augustine and St. Thomas Aquinas that a different approach is found, one that puts emphasis on the relational and responsive character of a person, rather than on the autonomous and auto telic dimension. According to Housset, such a dimension appears together with the idea of the person as a creation, and in opposition to the idea of the rational individual, that is his own master. The emotional dimension and the personality that is awoken by the many figures of alterity are some of the dimensions of the person that the author analyzes, based on examining the flesh, passions, memory historicity and love.

Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

Nos sonhos traumáticos, segundo Ferenczi, já existe a convocação de um terceiro. Não se trata da testemunha da esfera do Direito, tampouco do lugar do pai ou da Lei simbólica. Trata-se de um terceiro espaço que pode ser chamado de potencial, espaço intersticial, indeterminado e informe no qual circula - e aos poucos ganha forma -, algo que a princípio seria incomunicável. Esse espaço permite e suporta a literalidade da narrativa testemunhal, seus titubeios, paradoxos e silêncios. Mais do que uma teoria do trauma, a noção de espaço potencial seria a grande contribuição da psicanálise às pesquisas teóricas e clínicas com sobreviventes de campos de extermínio, de situações de tortura e de violência.

    We investigated whether impaired flow-mediated dilation (FMD) and plasma biomarkers reflecting endothelial dysfunction are associated with coronary microvascular dysfunction (CMD) in women with angina and no obstructive coronary artery disease (CAD). Patients (n = 194) were randomly selected women with angina pectoris and no obstructive CAD (<50% stenosis). A reference population of asymptomatic women without CAD (n = 25) was included. We measured FMD in the brachial artery by high-resolution ultrasound. Coronary flow velocity reserve (CFVR) was assessed by transthoracic Doppler flow echocardiography (TTDE) of the left anterior descending artery during rest and high-dose dipyridamole infusion. CMD was defined as CFVR <2. FMD and CFVR were measured in 128 patients and 21 controls. Mean (SD) age was 64.5 (8.9) years, mean CFVR was 2.3 (2.0-2.7), and mean FMD was 8.4% (4.8%) in angina patients. Angina patients had a higher risk factor burden compared with the reference population. Measures of peripheral endothelial dysfunction and endothelial plasma biomarkers did not differ according to angina or CFVR. CFVR and FMD did not correlate (Spearman ρ = -0.07, p = 0.45). FMD and biomarkers of endothelial dysfunction did not identify individuals with CMD assessed as impaired CFVR by TTDE in women with angina and no obstructive CAD. © 2017 S. Karger AG, Basel.

    Late onset of angina pectoris associated with subclavian artery (SA) atherosclerotic occlusive disease is a rare and recognized cause of myocardial ischemia when the lesion is proximal to a left internal mammary artery (LIMA) to coronary bypass. The symptoms typically exacerbate by increasing the flow demand in the extremity; this phenomenon is known as late coronary-subclavian steal syndrome. We describe the case of a 66-year-old woman who underwent coronary artery bypass grafting from the LIMA to the left anterior descending coronary artery in 2000. Years later, she experienced refractory angina pectoris associated to an occlusive lesion in the proximal left SA. SA endarterectomy with eversion technique and subclavian-carotid transposition restored the antegrade flow with resolution of the symptomatology. Copyright © 2016 Elsevier Inc. All rights reserved.

    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 heart disease(CHD) has become a major public health problem in the world, while the unstable angina (UA) is one of an important type. Hypofunction of yang qi in chest and cardiac blood stasis has been considered as the basic pathogenesis of UA.According to the deficiency of yang and blood stasis run through the process of CHD, fu yang and activating blood circulation could be main treatment. Wenxin decoction which has the function of fu yang and activating blood circulation, not only can effectively improve the symptoms of angina pectoris, the ischemic ECG, but also can significantly improve blood rheology, blood lipids and so on. So deepening the theory of ″fu yang and activating blood circulation″ and the application of ″Wenxin decoction″ in the treatment of UA would have an important clinical value for improving the therapeutic efficacy of CHD.

    This study aims to assess the predictive role of the preprocedural circulating monocyte to high-density lipoprotein (HDL) cholesterol ratio (MHR) on the occurrence of stent restenosis (SR) in patients with stable and unstable angina pectoris undergoing successful bare-metal stenting (BMS). Between February 2008 and June 2014, a total of 831 patients with stable and unstable angina pectoris who underwent successful BMS were retrospectively analyzed. Demographic and clinical characteristics of the patients were recorded. Left ventricular ejection fraction and laboratory data were also noted. In the receiver operating characteristics curve analysis, MHR >14 had 71% sensitivity and 69% specificity in predicting SR. Our study results show that preprocedural MHR is an independent predictor of SR in this patient population.

We have looked at the notion of the imperativeness of Law the central theme of the work -drawing on the views of Miguel Reale, for whom the juridical nonn cannot be reduced to a "command of a volitional nature", but rather the obligatory character of the juridical nonn arises from the pressure of social values. Del Vecchio, who is also quoted, recognized that imperativeness exists in the juridical norm, whether it is preceptive (a positive command or permissive. Also mentioned is the opinion of Tercio Sampaio Ferraz, for whom the juridical norm has imperativeness to the extent that the imposition of behaviour is unconditionally guaranteed.

    Full Text Available Introduction. Abdominal angina, also known as chronic mesenteric ischemia or intestinal angina, is a rare disease caused by intestinal flow reduction due to stenosis or occlusion of mesenteric arteries. A case of successful treatment of a patient with abdominal angina by percutaneous transuliminal angioplasty of high-grade superior mesenteric artery and coeliac trunk stenosis was presented. Case Outline. A 77-year-old male patient was admitted at our Clinic for severe postprandial abdominal pains followed by frequent diarrhoeas. Extensive gastrointestinal investigations were performed and all results were normal. Multislice computerized (MSCT arteriography was indicated which revealed ostial celiac trunk and superior mesenteric artery subocclusion. Percutaneous transluminal angioplasty of the superior mesenteric artery and coeliac trunk was done with two stents implantation. Just a few hours following the intervention, after food ingestion, there were no abdominal pains. Six months later, the patient described a significant feeling of relief after food ingestion and no arduousness at all. Conclusion. High-grade visceral arteries stenoses in patients with intestinal ischemia symptoms can be treated by either surgical procedures or percutaneus transluminal angioplasty. In cases when a low operative risk is anticipated, surgical treatment is recommended due to a better anatomical outcome, while percutaneus angioplasty is advised to elderly patients in whom increased operative risks can be expected.

    This study investigated the changes in the blood rheology of patients with angina pectoris and ischemia reperfusion injury and their effect on thromboxane B 2 (TXB 2 ) levels to examine their relationship. Forty patients with unstable angina pectoris who underwent elective percutaneous coronary intervention (PCI) were selected for the unstable angina group (UA group) and forty patients deemed free of coronary heart disease by coronary angiography were selected for the control group. Venous blood samples were drawn from all participants; patients in the UA group had blood drawn 1 day before and 1 day after the PCI procedure. Blood samples were used to analyze blood rheology and examine hemodynamic parameters, at the same time radioimmunoassay was applied to measure the concentrations of serum endothelin-1 (ET-1) and TXB 2 , and an automatic biochemical analyzer was used to detect the content of superoxide dismutase (SOD) and malondialdehyde (MDA). Our results showed the patients in the UA group all presented hyperviscosity; however the levels were higher for the patients in the UA group (after surgery) than for those in the UA group (before surgery). Patients in the control group exhibited normal levels, and the differences among groups were significant in pairwise comparisons (Pangina pectoris and ischemia reperfusion injury. The higher than normal TXB 2 levels can be used as a marker of platelet activation and a reference for clinical risk stratification, thus having great significance for the prevention and treatment of ischemia reperfusion injury and assessment of disease progression.

    Full Text Available Objective To analyze and compare the differentially expressed plasma proteins between patients with stable angina pectoris (SAP and unstable angina pectoris (UAP, and search for the biomarkers that maybe used for early diagnosis of UAP. Methods Sixty plasma samples were collected respectively from normal controls group (N group, SAP group and UAP group during Jun. 2014 to Apr. 2015 from the Third Affiliated Hospital of Southern Medical University. Ten samples (100μl of each group were selected randomly to pool into 3 groups severally. After removing high-abundance proteins from plasma, two- dimensional difference gel electrophoresis (DIGE was used to isolate the total proteins, and then the protein spots with more than 2-fold changes between UAP and SAP were picked up after the differential software analysis. Afterward, the varied proteins were identified by matrix assisted laser desorption ionization-time of flight/time of flight (MALDI-TOF/TOF mass spectrometry (MS. Finally, 40 plasma samples were collected respectively from N, SAP and UAP group, and the UAP specific differential proteins were selected to be verified by ELISA. Results A total of 10 varied protein spots with more than 2-fold changes in UAP and SAP were found including 9 up-regulated proteins and 1 down-regulated one. MS identification indicated that the up-regulated proteins included fibrinogen gamma chain (FGG, complement C4-B (C4B, immunoglobulin (Ig kappa chain C region (IGKC and hemoglobin subunit alpha (HBA1, whereas the down-regulated one was haptoglobin (HP. After comparing the varied proteins with that in N group, 2 specifically UAP-related proteins, IGKC and HP, were detected totally. IGKC was selected to validate by ELISA, and the corresponding results showed that IGKC was increased specifically in UAP plasma (P<0.05 when compared with N and SAP group, which was consistent with DIGE. Conclusion IGKC and HP have been detected as specifically related proteins to UAP

    Full Text Available The diagnosis of stable angina involves the use of probability estimates based on clinical presentation, age, gender and cardiovascular risk factors. In view of the link between the cardiac and systemic vasculature we tested whether non-invasive measures of systemic micro- and macrovascular structure and function differentiate between individuals with flow-limiting coronary artery disease (CAD and those with normal coronary arteries (NCA.We recruited 84 patients undergoing elective coronary angiography for investigation of symptoms of stable angina. Patients were selected for either having significant CAD or NCA (n = 43/41; age, 56±7 vs 57±7 years, P = 0.309. Only microvascular endothelial function, measured using the Endo-PAT2000 device to determine reactive hyperaemia index (CAD vs. NCA; 1.9 [1.5; 2.3] vs. 2.1 [1.8; 2.4], P = 0.03 and sonographic carotid plaque score (CAD vs. NCA; 3.0 [1.5; 4.5] vs. 1.2 [0; 2.55], P<0.001 were significantly different between patients with CAD and NCA. No significant differences were detected in reflection magnitude (CAD vs. NCA; 1.7 [1.5; 1.8] % vs 1.7 [1.5; 1.9] %, P = 0.342, pulse wave velocity (CAD vs. NCA; 7.8±1.4 m/sec vs. 8.3±1.5 m/sec, P = 0.186, carotid intima-media thickness (CAD vs. NCA; 0.73±0.10 mm vs. 0.75±0.10 mm, P = 0.518 or carotid distensibility (CAD vs. NCA; 3.8±1.2 10-3/kPa vs. 3.4±0.9 10-3/kPa, P = 0.092. Also, the c-statistic of the pre-test probability based on history and traditional risk factors (c = 0.665; 95% CI, 0.540-0.789 was improved by the addition of the inverse RHI (c = 0.720; 95% CI, 0.605-0.836, carotid plaque score (c = 0.770, 95% CI, 0.659-0.881, and of both markers in combination (c = 0.801; 95% CI, 0.701-0.900.There are distinct differences in the systemic vasculature between patients with CAD and NCA that may have the potential to guide diagnostic and therapeutic decisions. Carotid artery plaque burden and microvascular function appear to be most promising in

    Full Text Available Abstract Background Rural-to-urban migration in low- and middle-income countries causes an increase in individual cardiovascular risk. Cost-effective interventions at early stages of the natural history of coronary disease such as angina may stem an epidemic of premature coronary deaths in these countries. However, there are few data on the prevalence of angina in developing countries, whilst the understanding the aetiology of angina is complicated by the difficulty in measuring it across differing populations. Methods The PERU MIGRANT study was designed to investigate differences between rural-to-urban migrant and non-migrant groups in specific cardiovascular disease risk factors. Mass-migration seen in Peru from 1980s onwards was largely driven by politically motivated violence resulting in less 'healthy migrant' selection bias. The Rose angina questionnaire was used to record chest pain, which was classified definite, possible and non-exertional. Mental health was measured using the General Health Questionnaire (GHQ-12. Mantel-Haenszel odds ratios (adjusted for age, sex, cardiovascular disease risk factors and mental health were used to assess the risk of chest pain in the migrant and urban groups compared to the rural group, and further to assess the relationship (age and sex-adjusted between risk factors, mental health and chest pain. Results Compared to the urban group, rural dwellers had a greatly increased likelihood of possible/definite angina (multi-adjusted OR 2.82 (1.68- 4.73. Urban and migrant groups had higher levels of risk factors (e.g. smoking - 20.1% urban, 5.5% rural. No diabetes was seen in the rural dwellers who complained of possible/definite angina. Rural dwellers had a higher prevalence of mood disorder and the presence of a mood disorder was associated with possible/definite angina in all three groups, but not consistently with non-exertional chest pain. Conclusion Rural groups had a higher prevalence of angina as

    The implementation of new diagnostic and therapeutic technologies is related to expanding financial needs. The escalation of expenses for health protection and simultaneous economic problems has resulted in an interest in the subject of economic assessment. Decision makers in the health sector should have reasonable tools that will allow them to make complex evaluations of the economic suitability of health technologies. Economic analysis should also prove that launching new procedures can save money. Numerous studies indicate that chronic pain and psycho-sociological variables lead to a worse quality of life. Chronic pain issues are a major public health problem, by virtue of the difficulties in efficient therapy and the social costs reflected in incapability of work and disability. Spinal cord stimulation is the most efficacious procedure in the treatment of chronic pain. The aim of the study was to estimate the costs of treatment of 37 patients suffering from refractory angina pectoris and neuropathic pain who underwent SCS surgery between 2002 and 2008 in the Neurosurgery Clinic of the 10th Military Hospital in Bydgoszcz in the period of two years before and two years after spinal cord stimulation. The authors also assessed quality of life, using the SF 36 questionnaire, and degree of pain using VAS. The issue was examined with a cost-benefit analysis. Cost was understood as the expenses made two years before and two years after the SCS procedure. The benefits were health care expenses saved by implementation of the SCS procedure. All the costs included in both alternative treatment techniques in a period of 5 years underwent a discounting procedure. The authors also included the price of the neurostimulator under a sensitivity analysis. To assess the quality of life before and after the SCS procedure, a SF 36 questionnaire was used, and to assess the level of pain before and after the SCS procedure, the VAS scale. The costs of treatment of refractory angina

    In order to evaluate the therapeutic effects of metoprolol, nifedipine, and their combination, 11 patients with secondary angina pectoris and with thallium tomographic findings indicating coronary artery disease were studied before and after these three treatment regimes in a single-blind cross-over study. The therapeutic effect was measured by standardized working test and isotope angiocardiography, which enabled evaluation of left ventricular ejection fraction, stroke volume, and phase analysis of left ventricular contraction. Treatment with metoprolol and combination therapy increased work performance. Ejection fraction did not differentiate the treatment regimes, whereas stroke volume was significantly lower at work and heart rate higher at rest and at work during nifedipine treatment compared to either metoprolol or combination treatment (p less than 0.05). Cardiac output was significantly reduced during nifedipine and metoprolol treatment during work (p less than 0.05). Phase improved after all therapeutic regimes, but reached significance only during the metoprolol treatment period at rest (p less than 0.05).

    To examine the mechanism of occurrence of anginal chest pain from the aspect of myocardial ischemia, myocardial Tl-201 SPECT scans were obtained immediately and 3 hr after exercise (Ex) in 35 patients with coronary artery disease (CAD). The extent of ischemia was defined as the percentage of ischemic segments to the entire left ventricle. The minimum washout (WO) rate correlated well with the ratio of Tl uptake in the ischemic area to that in the normal area during Ex in the other 9 patients having single vessel CAD without previous history of myocardial infarction. This suggested that the miminum WO rate reflects the severity of Ex-induced ischemia. According to the development of angina during Ex, patients were classified as having either symptomatic ischemia (n = 16) or silent ischemia (n = 19). In regard to age, sex, a history of myocardial infarction, severity of CAD, and the extent of Ex-induced ischemia, there was no difference between the two groups. The minimum WO rate and the incidence of Ex-induced ST depression were significantly lower and higher, respectively, in the group with symptomatic ischemia than that with silent ischemia. The severity of Ex-induced ischemia has important implications for the development of anginal chest pain. (Namekawa, K.)

    Full Text Available Patients with Glanzmann thrombasthenia fail to form large platelet thrombi due to mutations that affect the biosynthesis and/or function of the αIIbβ3 integrin. The result is a moderate to severe bleeding syndrome. We now report unusual vascular behaviour in a 55-year-old woman with classic type I disease (with no platelet αIIbβ3 expression and a homozygous ITGA2B missense mutation (E324K affecting the terminal β-propeller domain of αIIb. While exhibiting classic bleeding symptoms as a child, in later life this woman first developed deep vein thrombosis after a long air flight then showed vascular problems characteristic of Raynaud’s phenomenon, and finally this year she presented with chest pains suggestive of coronary heart disease. Yet while coronary angiography first showed a stenosis, this was not seen on a second examination when she was diagnosed with coronary spastic angina and Prinzmetal phenomenon. It is significant that the absence of platelet aggregation with physiologic agonists had not prevented any of the above cardiovascular or vascular diseases.

    Full Text Available Coronary cameral fistulas are abnormal communications between a coronary artery and a heart chamber or a great vessel which are reported in less than 0.1% of patients undergoing diagnostic coronary angiography. All three major coronary arteries are even less frequently involved in fistula formation as it is the case in our patient. A 68-year-old woman was admitted to cardiology clinic with complaints of exertional dyspnea and angina for two years and a new onset palpitation. Standard 12-lead electrocardiogram revealed atrial fibrillation (AF with a ventricular rate of 114 beat/minute and accompanying T wave abnormalities and minimal ST-depression on lateral derivations. Transthoracic echocardiographic examination was normal except for diastolic dysfunction, minimally mitral regurgitation, and mild to moderate enlargement of the left atrium. Sinus rhythm was achieved by medical cardioversion with amiodarone infusion. Coronary angiography revealed diffuse and multiple coronary-left ventricle fistulas originating from the distal segments of both left and right coronary arterial systems without any stenosis in epicardial coronary arteries. The patient’s symptoms resolved almost completely with medical therapy. High volume shunts via coronary artery to left ventricular microfistulas may lead to increased volume overload and subsequent increase in end-diastolic pressure of the left ventricle and may cause left atrial enlargement.

    The mechanism of ischaemic ST depression and the cause of its low sensitivity to coronary artery stenosis are not well understood. Of 30 patients with severe stable effort angina, 19 (63%) showed ischaemic ST depressions after exercise (the STAE group) and 11 did not. The highest load during the symptom-limited exercise test and the heart rate on that load did not differ between the two groups. The clinical characteristics and angiographic findings were also similar, but the findings at heart catheterization differed during exercise (in supine). Although the load was similar, the stroke index was significantly lower (38 vs. 53 ml/m2 BSA) and the left ventricular end-diastolic pressure rose to a significantly higher value in the STAE group (40 vs. 32 mmHg). When STAE occurred, they were exclusively or concomitantly present in chest lead 5. These findings suggest that ischaemic STAE may not reflect regional ischaemia but the consequent left ventricular dysfunction. The mechanism may, for example, be that a sufficiently elevated left ventricular diastolic pressure causes a global subendocardial ischaemia.

    To initially optimize comprehensive treatment program for treating and preventing unstable angina (UA) by integrative medicine (IM). Based on partially observable Markov decision process model (POMDP), we chose 3 syndrome elements, i.e., qi deficiency, blood stasis, and phlegm turbidity from UA inpatients. The efficacy of treating UA by IM was objectively assessed by in-depth data mining and analyses. The treatment programs for UA patients of qi deficiency syndrome, blood stasis syndrome, and phlegm turbidity syndrome were recommended as follows: nitrates +statins +clopidogrel +angiotensin II receptor blockers +heparins +Astragalus membranaceus +Condonopsis + poria and large-head atractylodes rhizome (ADR = 0.85077869); nitrates + aspirin + clopidogrel + statins + heparins + Astragalus membranaceus + safflower + peach seed + red peony root (ADR = 0.70773000); nitrates + aspirin + statins + angiotensin-converting inhibitors + snakegourd fruit + onion bulb + ternate pinellia + tangerine peel (ADR = 0.72509600). As a POMDP based optimized treatment programs for UA, it can be used as a reference for further standardization and formulation of UA program by integrative medicine.

    Eosinophils (EOS) have been associated with prognosis of patients with coronary artery disease, and those who showed plenitudinous coronary collateral circulation (CCC) often have good clinical consequences. However, the relationship between EOS and CCC was seldom reported. To investigate the relationship between EOS and CCC development in patients with unstable angina pectoris (UAP). The study population consisted of 502 consecutive patients with UAP who underwent coronary angiography and coronary stenosis ≥80%. CCC was graded according to the Rentrop grading system of 0-3. Rentrop grades of 0 and 1 indicated low-grade CCC group, whereas grades 2 and 3 indicated high-grade CCC group. The EOS was significantly higher in the high-grade CCC group compared with the low-grade CCC group. In multiple logistic regression analysis, EOS (odds ratio: 1.969; 95% confidence interval [CI]: 1.210-3.3205; P=0.006) and neutrophil count (odds ratio: 0.757; 95% CI: 0.584-0.981; P=0.035) were predictors of high-grade CCC development. EOS of >0.12×10(9)/L could independently predict high-grade CCC with 72.5% sensitivity and 58.4% specificity (area under the curve: 0.681; 95% CI: 0.632-0.729). EOS were associated with high-grade CCC in patients with UAP with coronary stenosis ≥80%. Increased EOS count may play an important role in the development of CCC in patients with UAP.

    (1)H NMR-based urinary metabolic profiling is used for investigating the unstable angina pectoris (UAP) metabolic signatures, in order to find out candidate biomarkers to facilitate medical diagnosis. In this work, 27 urine samples from UAP patients and 20 healthy controls were used. The metabolic profiles of the samples were analyzed by multivariate statistics analysis, including PCA, PLS-DA and OPLS-DA. The PCA analysis exhibited slight separation with R(2)X of 0.681 and Q2 of 0.251, while the PLS-DA (R(2)X = 0.121, R(2)Y = 0.931, and Q(2) = 0.661) and the OPLS-DA (R(2)X = 0.121, R(2)Y = 0.931, Q(2) = 0.653) demonstrated that the model showed good performance. By OPLS-DA, 20 metabolites were identified. A diagnostic model was further constructed using the receiver-operator characteristic (ROC) curves (AUC = 0.953), which exhibited a satisfying sensitivity of 92.6%, specificity of 90% and accuracy of 89.1%. The results demonstrated that the NMR-based metabolomics approach showed good performance in identifying diagnostic urinary biomarkers, providing new insights into the metabolic process related to UAP.

    To investigate whether sodium tanshinone IIA silate (STS) as an add-on therapy to conventional treatment may provide additional benefits for patients with unstable angina pectoris (UAP) and is associated with changes in profiles of serum inflammatory factors. Eighty patients diagnosed with UAP were randomly divided into two groups for the 2-week treatment. The control group received conventional therapy, while the treatment group was given intravenous STS (0.06 mg in 250 mL, once daily) as an add-on therapy to the conventional medications. The therapeutic efficacy and changes in serum levels of several inflammatory cytokines, including monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor alpha (TNF-α), peroxisome proliferator-activated receptor (PPAR-γ), and high-sensitivity C-reactive protein (hs-CRP) from baseline were determined and compared between the two group. The clinical symptoms of all patients in both groups were improved after treatment. The overall rate of effectiveness was 97.5% in the treatment group vs. 80.0% in the control group. Serum levels of MCP-1, TNF-α, and hs-CRP levels were significantly reduced in both groups (P<0.01), whereas the reduction was greater in patients receiving additional STS (P<0.05). PPAR-γ was significantly elevated in both groups (P<0.01). STS in combination with conventional treatment may be associated with better outcomes in patients with UAP.

    While cardiac troponin measurements have significantly improved the early diagnosis of myocardial infarction, the timely biomarker-based diagnosis of unstable angina pectoris (UAP) remains a major unmet clinical challenge. The aim of this study was to assess levels of circulating microRNAs (miRNAs) as possible novel biomarkers in patients with UAP. A three-phase approach was conducted, comprising (i) profiling of miRNAs in patients with UAP and controls groups; (ii) replication of significant miRNAs in an independent patient cohort, (iii) validation of a multi-miRNAs panel in a third cohort. Out of 25 miRNAs selected for replication, 8 miRNAs remained significantly associated with UAP. In a validation phase, a miRNA panel including miR-132, miR-150, and miR-186 showed the highest discriminatory power [area under the receiver-operating-characteristic curve (AUC): 0.91; CI: 0.84-0.98]. Using a profiling-replication-validation model, we identified eight miRNAs, which may facilitate the diagnosis of UAP. Published on behalf of the European Society of Cardiology.

    2017-11-01

    Full Text Available Summary:. Negative-pressure wound therapy (NPWT is a well-established therapeutic approach for various complex wound classes. There is currently limited information on the use of NPWT for the scope of head and neck wounds. However, NPWT has been used successfully in some cases, including malignancy, infection, and trauma. In West Virginia, the incidence of dental-related infections leading to Ludwig’s Angina is high due to lack of access to dental care. Our case series describes the application of vacuum-based therapy in conjunction with antibiotic therapy for quick, effective closure of deep tissue infections before definitive complex wound repair via graft and flap reconstructions. Over a period of 3 months, 2 patients with submental infections extending to the lateral neck demonstrated clean, efficient wound closure with NPWT for less than 14 days while hospitalized at West Virginia University Medicine. Outpatient follow-up with these patients demonstrated excellent cosmetic outcomes with minimal contracture or hypertrophy of healing tissue. NPWT promotes wound healing through decreased edema, improved perfusion, and increased granulation of tissue based on our findings.

    Full Text Available Background. A prolonged coronary artery spasm with interruption of coronary blood flow can lead to myocardial necrosis and increase of cardiospecific enzymes and can be complicated with cardiac rhythm disturbances, syncopc, or even sudden cardiac death. Case report. A 55-year old male felt a severe retrosternal pain when exposing himself to cold weather. The pain lasted for 20 minutes and was followed by the loss of conscience. Electrocardiogram (ECG showed a complete antrioventricular (AV block with nodal rhythm and marked elevation of ST segment in inferior leads. Electrocardiogram was soon normalized, but serum activities of cardiospecific enzymes were increased. Coronarography showed normal findings for the left coronary artery and a narrowing at the middle part of the right coronary artery, which disappeared after intracoronary application of nitroglycerine. The following therapy was prescribed: Diltiazem, Amlodipin, Isosorbid mononitrate, Molisdomin, Atrovastatin, Aspirin and Nitroglycerine spray. After 7 months medicaments were abandoned and the patient experienced again reccurent chest pain episodes at rest. Transitory ST segment elevation was recorded in inferior leads of ECG, but without increase of cardiospecific enzymes serum activities. After restoration of the medicament therapy anginal episodes ceased. Conclusion. Coronary dilators in maximal doses can prevent attacks of vasospastic angina.

    Full Text Available Introduction & Objective: Unstable angina is in the center of spectrum from chronic stable angina to acute myocardial infarction. Due to high prevalence of unstable angina, it is important to find a factor that predicts prognosis and management modality. We decided to measure CRP level for the items that mentioned above.Materials & Methods: This study was a cross-sectional study that 138 patients who were admitted with unstable angina in the CCU and cardiac ward of Ekbatan Hospital in Hamedan were considered for measuring CRP level. Age, sex, period of disease, and left ventricular ejection fraction percentile were worked out. After quantitative CRP measuring and 14 days follow up, the questionnaire was completed.Results: CRP levels were 116.3 and 124.3 ng/ml in the patients with and without cardiovascular events (whole events respectively during 14 days follow up. Recurrent unstable angina, myocardial infarction and mortality rate were higher in the patients with elevated level of CRP but need to perform coronary angiography was lower.Conclusion: CRP level had no correlation with occurrence of cardiovascular events (whole events during 14 days follow up.

    Angina is a frequent symptom in patients with hypertrophic cardiomyopathy (HCM); however, it is often not because of significant epicardial coronary artery stenosis. Coronary CT angiography (CCTA) is an excellent modality to rule out significant coronary artery stenosis in the low- and intermediate-risk patients; however, its value in patients with HCM has not been explored. We sought to assess the utility of CCTA in the assessment of patients with HCM and stable anginal symptoms and compare the incidence of epicardial coronary artery stenosis to an age- and gender-matched control group. Consecutive outpatients with HCM referred for CCTA over a 3-year period because of stable anginal symptoms (chest pain or shortness of breath) were identified retrospectively. Age- and gender-matched patients without HCM referred for CCTA because of similar symptoms over a 6-month period were used as controls. All patients had CCTA using an Aquilion ONE 320 scanner. The coronary arteries were evaluated independently by 2 blinded observers, and any luminal narrowing was scored quantitatively as follows: >70% = severe; 50% to 70% = moderate; symptoms in patients with HCM. The incidence of moderate-to-severe coronary artery stenosis was significantly lower in our HCM patients in comparison to our age-matched, gender-matched, and risk factor-matched control group. Given the high incidence of false-positive findings on perfusion stress studies, we propose that CCTA may be useful for appropriate triage to coronary angiography in the HCM patient with anginal symptoms.

    Full Text Available Abstract Aim The inflammatory response, initiated by neutrophil and monocyte adhesion to endothelial cells, is important in the pathogenesis of acute coronary syndromes. Platelets play an important role in inflammatory process by interacting with monocytes and neutrophils. In this study, we investigated the effect of tirofiban on the levels of cell adhesion molecules (soluble intercellular adhesion molecule-1, sICAM-1, and vascular cell adhesion molecule-1, sVCAM-1 in patients with unstable angina pectoris (AP. Methods Thirty-five patients with unstable AP (Group I, ten patients with stable AP (Group II and ten subjects who had angiographycally normal coronary arteries (Group III were included the study. Group I was divided into two subgroups for the specific treatment regimens: Group IA (n = 15 received tirofiban and Group IB (n = 20 did not. Blood samples for investigating the cell adhesion molecules were drawn at zero time (baseline; 0 h in all patients and at 72 h in Group I. Results The baseline levels of sICAM-1 and sVCAM-1 were higher in Group I than in Groups II and III. They were higher in Group IA than in Group IB. However, the sICAM-1 and sVCAM-1 levels decreased significantly in Group IA after tirofiban infusion. In contrast, these levels remained unchanged or were increased above the baseline value in Group IB at 72 h. Conclusion The levels of cell adhesion molecules in patients with unstable AP decreased significantly after tirofiban infusion. Inhibition of platelet function by specific glycoprotein IIb/IIIa antagonists may decrease platelet-mediated inflammation and the ischemic end-point.

    There had been performed a research of an effectiveness of millimeter electromagnetic radiation (MM EMR) use in patients with an unstable angina (UA) at periods of a lower (daily value of Kp-index 16,19±0,18) and a higher (daily value of Kp-index 17,25±0,21, p<0,05) gemagnetic activity (GA). It was found that involving of the MM EMR (the wave length 7.1 mm) into the treatment of the patients with an UA, enhances an antianginal effect of a drug therapy independently on the period of GA. The MM EMR at the period of a lower geomagnetic activity (LGA) enhances the decrease of diastolic blood pressure (BP), and at the period of a higher geomagnetic activity (HGA) - the decrease of systolic BP. At a HGA there were noted: a quick and more serious antianginal effect, maximal antihypertensive effect was achieved quicker, but (as opposed to the period of a LGA) there was no a pulse slowing effect of a MM EMR. Including the MM EMR into the treatment accelerates stabilization of the patients' condition only at a LGA. Positive effect on blood rheological properties is an independent effect of MM EMR, and it is in blood viscosity reduce in microcirculatory at both of the periods of GA. Normalization of blood viscosity under the MM EMR is only at the period of a LGA. So, the effect of MM EMR on a clinical condition of the patients is more evident at the period of a HGA, blood viscosity - at the period of a LGA.

    Patients with diastolic heart failure (HF) i.e. clinical HF with normal or near normal left ventricular ejection fraction (LVEF) may experience unstable angina pectoris (UAP) due to epicardial atherosclerotic coronary artery disease (CAD) and/or to subendocardial ischemia, even in the absence of CAD. However, the risk of UAP among ambulatory diastolic HF patients has not been well studied. We examined incident hospitalizations due to UAP among 916 diastolic HF (LVEF >45%) patients without significant valvular heart disease and 6800 systolic HF (LVEF ≤45%) patients in the Digitalis Investigation Group trial. During a 38-month median follow-up, 12% (797/6,800) of systolic HF patients (incidence rate, 435/10,000 person-years) and 15% (138/916) of diastolic HF patients (incidence rate, 536/10,000 person-years) were hospitalized for UAP (adjusted hazard ratio for diastolic HF, 1.22; 95% confidence interval, 1.02–1.47; p=0.032). There was a graded increase in incident hospital admissions for UAP with increasing LVEF. Hospitalizations for UAP occurred in 11% (520/4,808; incidence rate, 407/10,000 person-years), 14% (355/2556; incidence rate, 496/10,000 person-years) and 17% (60/352; incidence rate, 613/10,000 person-years) of HF patients, respectively, with LVEF 55%. Compared with HF patients with LVEF 55% were respectively 1.17 (1.02–1.34; p=0.028) and 1.57 (1.20–2.07; p=0.026). In conclusion, in ambulatory chronic HF patients, higher LVEF was associated with increased risk of hospitalizations due to UAP. As in patients with systolic HF, those with diastolic HF should be routinely evaluated for myocardial ischemia and managed accordingly. PMID:17293184

    To evaluate systematically the efficacy and safety of Danshenchuanxiongqin Injection (DCI) in the treatment of unstable angina pectoris (UAP). Randomized controlled trials (RCTs) regarding DCI used for treating UAP were searched in English and Chinese electronic databases from inception to January 2014. Two reviewers independently retrieved RCTs and extracted relevant information. The Cochrane risk of bias method was used to assess the quality of included studies, and a Meta-analysis was conducted with Review Manager 5.2 software. Eleven RCTs involving 1034 participants were included. The methodological quality was relatively passable. The Meta-analysis indicated that the combined use of DCI and conventional treatment with Western Medicine (WM) was more efficacious in the outcomes of total effective rate [Relative Risk (RR) = 1.27, 95% CI (confidence interval; 1.18, 1.35), P < 0.000 01], the total effective rate of ECG [RR = 1.40, 95% CI (1.18, 1.66), P < 0.000 01], total cholesterol [Mean difference (MD) = -0.58, 95% CI (- 0.83, - 0.33), P < 0.000 01], total triglycerides [MD = - 0.36, 95% CI (- 0.54, - 0.17), P = 0.0001], and the number of ST-segment depression [MD = -0.36, 95% CI (- 0.54, - 0.17), P = 0.0001]. There were two adverse drug reactions reported in one study. Based on the systematic review, DCI combined with WM appeared to be efficacious in the treatment UAP. However, the evidence of DCI for treating UAP requires large-scale and double-blind RCTs to substantiate these findings.

    Diabetic microvascular changes are considered to be influenced by angiogenic factors. As a compensatory mechanism, the expression of some angiogenic factors are elevated in ischemic myocardium. The aim of this study was to investigate the changes of serum angiogenic factors, and the association among these angiogenic factors, the severity of coronary artery stenosis and collateral vessels form in patients with diabetes and unstable angina pectoris (UAP). 42 patients with diabetes (diabetes group), 57 patients with UAP (UAP group), and 36 age-matched healthy people (control group) were selected. Serum concentrations of angiogenic factors were measured using cytokine array technology. The severity of coronary artery stenosis was scored using the angiographic Gensini score. Coronary collateral vessels were scored according to Rentrop's classification. No significant differences in the serum concentrations of vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), angiogenin, angiostatin, basic fibroblast growth factor (bFGF) and platelet-derived growth factor-BB (PDGF-BB) were detected between control group and diabetes group. But in patients with diabetes complicated with UAP and in patients with UAP without diabetes, serum concentrations of VEGF and Ang-2 were elevated (p < 0.01, p < 0.01). Only serum Ang-2 concentrations were significantly correlated with Gensini score (r=0.585, p < 0.001), left ventricular end diastolic diameter (r=0.501, p < 0.001), left ventricular end systolic diameter (r=0.563, p < 0.001) and left ventricular ejection fraction (r=-0.523, p < 0.001). Serum concentrations of VEGF and Ang-2 were increased, and diabetes didn't affect this increases in patients with UAP. Serum Ang-2 concentrations were correlated with the severity of coronary artery stenosis.

    Ludwig's angina (LA) is an uncommon and potentially life-threatening condition of the upper aero-digestive tract that often requires the coordinated efforts of the surgical, anesthetic and intensive care teams to optimize management. The purpose of the present study was to investigate the documented clinical features and the surgical and airway management of LA at Alice Springs Hospital for the purpose of assessing surgical outcomes with particular reference to length of stay (LOS). Retrospective chart review from January 1998 to January 2008 examined patients admitted with LA at Alice Springs Hospital. Documented clinical features, interventions, and operative findings including floor of mouth swelling, Mallampati score, and airway compromise were collected. Outcomes, with particular respect to LOS, for those who received intravenous (IV) or inhalational induction and those that received awake fibre-optic intubations were compared. Of 30 patients with LA, 28 (93%) were managed with operative drainage with a LOS in the intensive care unit (ICU) of 2 days and a hospital LOS of 5 days. Seven received awake fibre-optic intubation and 21 had IV or inhalational anesthesia with none requiring tracheotomy. There was no statistical difference in LOS between those patients whose microbiological culture results showed no growth and those whose cultures had positive growth. Management was generally operative decompression with IV antibiotics. LOS is not affected by the presence or absence of culture positive infection. It is proposed that operative intervention is safe, effective, and is associated with shorter patient stays in the intensive care unit and the hospital overall. © 2010 The Authors.

    Ludwig's angina (LA) still presents regularly at our tertiary academic hospital. Various etiologies and comorbid diseases are documented worldwide, but the South African population has not been studied. To establish whether LA cases presenting to the department are different from international reports regarding etiology and comorbidities. Retrospective analysis of patients presenting with LA to a tertiary hospital. 93 patients were included over a 5-year period. Archived files were analyzed for data including age, gender, comorbid diseases, etiology, airway management, and season on admission. Descriptive statistics with the inclusion of frequency distributions. 93 patients were included; 65 (69.9%) male and 28 (30.1%) female; age - minimum 20 years, maximum 75 years, mean 40.366. 68 (73.1%) odontogenic, 13 (14%) nonodontogenic, and 12 (12.9%) unknown cause. Comorbid diseases: 21 (22.6%) diabetes mellitus (DM), 19 (20.4%) hypertension, and 18 (19.4%) human immunodeficiency virus (HIV). Airway management: 61 (65.6%) tracheostomy and 32 (34.4%) nonsurgical. 11 (11.8%) deaths, 8 (8.60%) descending mediastinitis, and 7 (7.53%) necrotizing fasciitis. Seasonal occurrence: 30 (32.3%) spring, 24 (25.8%) winter, 22 (23.7%) summer, and 17 (18.3%) autumn. A 2.32:1 ratio male: female presentation mirrors previous statistics. DM patients had increased risks of complications, which resulted in multiple deaths. HIV patients showed increased risks for complications with more intense, longer hospital stays, but lower percentages of deaths compared to patients with DM and complications who died. There was no statistically significant finding regarding seasonal tendency.

    1986-04-01

    In 1981, a large, double-blind, randomized trial was started in The Netherlands to evaluate the therapeutic effects of nifedipine and/or metoprolol in patients with unstable angina. This study has been called the Holland Interuniversity Nifedipine/metoprolol Trial (HINT) and required several hundred patients to establish potential therapeutic effects. From December 1982 to January 1984 the effects of nifedipine on left ventricular (LV) performance in a subgroup of 52 HINT patients were studied using radionuclide techniques. All patients (23 on nifedipine, 29 controls) underwent thallium-201 scintigraphy or radionuclide angiography just before and 48 h after the start of experimental medication. The radionuclide angiographic studies were also performed at 1 and 4 h after treatment. Nifedipine did not influence the incidence of disapperance of perfusion defects on the 48-h thallium images. No significant differences in overall LV ejections fraction (EF) were seen at any time between nifedipine-treated patients and controls. However, paired observations in 37 patients showed improvement of LVEF after 48 h in 8 patients on nifedipine and in only 1 control patient. Scintigraphic measurements on admission were not related to clinical outcome after 48 h. Concomitant administration of metoprolol did not influence LVEF in either group. It is concluded that nifedipine improves LVEF after 48 h in a subset of patients with unstable angina without affecting myocardial perfusion. This finding indicates that nifedipine has a predominant effect on afterload reduction in patients with unstable angina. Also, early scintigraphic measurements had no significant predictive value for subsequent cardiac events.

    Aim Collagens are major cardiac extracellular matrix components, known to be actively remodelled and accumulated during diffuse myocardial fibrosis. We evaluated whether accelerated collagen turnover described by neo-epitope biomarkers reflecting collagen formation and degradation separates patients with diffuse myocardial fibrosis from asymptomatic controls. Methods and results Seventy-one women with angina pectoris without significant coronary artery disease assessed by invasive coronary angiogram were included. Competitive enzyme-linked immunosorbent assays (ELISAs) measuring circulating protein fragments in serum assessed the formation and degradation of collagen type III (Pro-C3, C3M and C3C), IV (P4NP7S and C4M), V (Pro-C5 and C5M) and VI (Pro-C6 and C6M), and degradation of collagen type I (C1M). Serum samples from 32 age-matched asymptomatic women were included as controls. Symptomatic women presented significantly elevated levels of Pro-C6, C3C, C3M, C4M and C8-C ( p < 0.0001-0.0058) and significantly decreased levels of Pro-C3, C5M and C6M ( p < 0.0001-0.041), reflecting accelerated collagen turnover and an imbalanced collagen formation and degradation compared to controls. Cardiac magnetic resonance T1 mapping was performed to determine extracellular volume fraction and thus diffuse myocardial fibrosis. A significant association was identified between C5M and extracellular volume fraction by cardiac magnetic resonance ( p = 0.01). Conclusion Women with angina pectoris, but without significant obstructive coronary artery disease, showed an imbalanced collagen turnover compared to asymptomatic controls. The examined biomarkers are tools to monitor active collagen remodelling in patients with angina pectoris, in risk of developing myocardial fibrosis.

    Background: The complicated concept of quality of life (QOL) has been considered as an important criterion for health outcomes in chronic diseases, such as heart disease, in recent years. The aim of this study was to evaluate the QOL of patients with angina pectoris after treatment with enhanced external counterpulsation (EECP). Materials and Methods: This quasi-experimental study was conducted on 64 patients with angina pectoris undergoing EECP who came to Shahid Chamran and Sina Hospitals in Isfahan. Sampling was performed by the convenient method. Data were collected using a questionnaire containing socio-demographic and clinical data. A standard questionnaire called 36-item Short-Form Health Survey was also used. Questionnaires were completed through interviews and phone calls in three stages (before, immediately and three months after the treatment). The results were analyzed using descriptive statistics (frequency, mean, and standard deviation) and analytical statistics (paired t-test and repeated measures test) in SPSS11.5. Findings: The obtained results demonstrated that the majority of patients were men (59.4%) and aged 56-71 years. In addition, 57.8% had hypertension and 56.3% had hyperlipidemia. A history of myocardial infarction was found in 70.3% of the subjects and the familial history of coronary artery disease was detected in73.4%. Although QOL evaluations showed improvements in all subscales immediately and three months after the treatment, the changes were not statistically significant in case of general health, role limitations due to physical problems and role limitations due to mental problems Conclusions: Similar to previous research, this study showed QOL to improve in patients who undergo EECP. This improvement will remain stable three months after the treatment in all subscales. Therefore, EECP is an efficient noninvasive method in treating patients with angina pectoris and in developing their QOL. PMID:23493242

    Ischemia modified albumin (IMA) was registered by the United States Food and Drug Administration as a marker of myocardial ischemia. To assess the usefulness of IMA measurement for differentiating patients with acute coronary syndrome (ACS) with no ST elevation and patients with unstable angina pectoris. The study group consisted of 121 patients (mean age 63 +/- 12 years, 84 males), who were admitted to our department with retrosternal chest pain occurring at rest and lasting more than 20 minutes. The patients had laboratory tests performed including aspartate aminotransferase, izoenzyme of creatine kinase activity, troponin T, N-terminal pro-brain natriuretic peptide (NT-proBNP), C-reactive protein, IMA concentration and creatinine clearance. Coronary angiography was also performed. All study patients were divided into 2 groups: group I with elevated troponin concentration (58 patients) and group II with troponin concentration below reference value (63 patients). The IMA concentration in the serum did not differ significantly between group I (troponin positive) and group II (troponin negative) (95.2 +/- 12.8 U/mL vs 94.0 +/- 17.9 U/mL, NS). The percentage of patients with elevated IMA values (cut off point of 85 U/mL) did not differ significantly between group I and group II patients (76.6% vs 76.2%, NS). In patients from group I an upward trend was noted, whereas in patients from group II a downward trend was associated with the duration of ischemic chest pain. In group I the correlation between the IMA concentration and the NT-proBNP concentration was positive (R = 0.2957; p unstable angina. 2. The upward trend of IMA concentration was associated with the duration of chest pain in patients with ACS, whereas the opposite trend was found in patients with unstable angina pectoris.

    The objective of this study was to assess the relative value of invasive and noninvasive predictors of outcome in patients after unstable angina. Fifty-four patients with unstable angina who had 6-month follow-up after stabilization on medical therapy were evaluated. We prospectively compared 24-hour Holter ST-segment monitoring at admission, quantitative exercise thallium tomography, and cardiac catheterization 5 +/- 2 days after admission and analyzed their value for predicting a cardiac event in patients with unstable angina within 6 months. When patients with a favorable outcome (n = 40) were compared with patients with an unfavorable outcome (n = 11) no statistical difference was found in duration of ST shift of 1 mm or more on Holter monitoring (51 +/- 119 min compared with 37 +/- 43 min), exercise duration by the standard Bruce protocol (8.0 +/- 3.6 min compared with 7.9 +/- 3.1 min), exercise-induced ST depression (0.6 +/- 0.9 mm compared with 1.0 +/- 1.0 mm), and contrast left ventricular ejection fraction (70% +/- 10% compared with 69% +/- 15%). Patients with a favorable outcome were distinguished from those with an unfavorable outcome by a higher maximum rate-pressure product (24 x 10(3) +/- 6 x 10(3) compared with 18 x 10(3) +/- 7 x 10(3), P = 0.0025), smaller size of the reversible scintigraphic perfusion defect expressed as a percentage of total myocardium imaged (6% +/- 11% compared with 17% +/- 18%, P = 0.05) and a smaller number of vessels with stenosis of 50% or more (1.1 +/- 1.2 compared with 2.1 +/- 1.0, P = 0.01). On multiple logistic regression analysis, a history of previous myocardial infarction was the most powerful predictor of outcome. In patients without myocardial infarction, reversible exercise thallium perfusion defect size was the only predictor

    Several preference-based health-related quality of life (HRQoL) instruments have been published and widely used in different populations. However no consensus has emerged regarding the most appropriate instrument in therapeutic area of stable angina. This study compared and validated the psychometric properties of two generic preference-based instruments, the EQ-5D and SF-6D, among Chinese stable angina patients. Convergent validity of the EQ-5D and SF-6D was examined with eight a priori hypotheses from stable angina patients in conjunction with Seattle Angina Questionnaire (SAQ). Responsiveness was compared using the effect size (ES), relative efficiency (RE) and receiver operating characteristic (ROC) curves. Agreement between the EQ-5D and SF-6D was tested using intra-class correlation coefficient (ICC) and Bland-Altman plot. Factors affecting utility difference were explored with multiple linear regression analysis. In 411 patients (mean age 68.08 ± 11.35), mean utility scores (SD) were 0.78 (0.15) for the EQ-5D and 0.68 (0.12) for the SF-6D. Validity was demonstrated by the moderate to strong correlation coefficients (Range: 0.368-0.594, Pstable-angina-specific health status than the EQ-5D (ES: 0.426 to 1.126). RE suggested that the SF-6D (RE: 44.8 to 177.8%) was more efficient than the EQ-5D except for physical function. Poor agreement between them was observed with ICC (0.448, Pstable angina patients. The SF-6D may be a more effective tool with lower ceiling effect and greater sensitivity. Further study is needed to compare other properties, such as reliability and longitudinal response.

    Full Text Available Introduction. Adherence to proposed lifestyle changes and prescribed medication in patients with stable coronary artery disease (SCAD is poor. Objective. We sought to investigate the influence of adjusting guideline proposed medications on relief of angina in a large group of patients with SCAD in Serbia. Methods. The study included a total of 3,490 patients from 15 cardiology clinics with symptoms of stable angina and at least one of the following criteria: abnormal electrocardiogram (ECG, history of myocardial infarction (MI, positive stress test, significant coronary artery disease on coronary angiogram or previous revascularization. All the patients underwent comprehensive evaluation at initial visit and after two months. The relief of angina was study end-point defined as any reduction in Canadian Cardiology Society (CCS class, number of angina attacks per week and/or number of tablets of short-acting nitrates per week. Results. Most patients were included based on abnormal ECG (48.4%. At Visit 1, the average number of prescribed classes of medications to a single patient increased from 4.16 ± 1.29 to 4.63 ± 1.57 (p < 0.001. At the follow-up, the patients had significantly lower blood pressure (141 ± 19 / 85 ± 11 vs. 130 ± 12 / 80 ± 8 mmHg; p < 0.001 and most of them reported CCS class I (63.3%. The average weekly number of angina attacks was reduced from 2.82 ± 2.50 at Visit 1 to 1.72 0 ± 1.66 at Visit 2, as well as average weekly use of short-acting nitrates to treat these attacks (2.69 ± 2.53 to 1.74 ± 1.47 tablets; p < 0.001 for all. Conclusion. Adjustment of prescribed medications to guideline recommendations in a large Serbian patient population with prevalent risk factors led to significant relief of angina.

    Full Text Available Introduction and Objectives: Microvascular angina is common in postmenopausal women. Myocardial ischemia was induced by stress testing, and reports have been published about the relationship between endothelial dysfunction and myocardial perfusion. The objective of this research was to determine whether myocardial ischemia can be evidenced by abnormalities in perfusion and function, as detected by myocardial scintigraphy in women with typical angina, normal coronary angiography and endothelial dysfunction. Methods: 59 women underwent lipid and endothelial function measurements by brachial artery ultrasound, in addition, a 24-hour ECG study (Holter. During the scintigraphy a stress-rest protocol was applied. Patients were divided into two groups according to presence (group I or absence (group II of myocardial perfusion defects. Results: 21 patients showed perfusion defects. 57 % of group I exhibited greater endothelial dysfunction. Only twelve patients showed reversible perfusion defects, and 75 % of the cases was associated with a reduction of post-stress left ventricular ejection fraction, greater than 5 %, and regional abnormalities of wall motion. Three patients in group I showed evidence of ischemia compared with four in Group II. Conclusions: The stress-induced ischemia was associated with a reduced post-stress ejection fraction and endothelial dysfunction in the studied women, and no ischemic changes in the Holter were found.

    There is little information about the relationship between J waves and the occurrence of ventricular fibrillation (VF) in patients with vasospastic angina (VSA). The present study aimed to assess the incidence of J waves and the occurrence of VF in patients with VSA. The subjects consisted of 62 patients with VSA diagnosed by acetylcholine provocation tests in our institution from 2002 to 2014. We investigated the VF events, prevalence of J waves, and relationship between the VF events and J waves. J waves were observed in 16 patients (26%) and VF events were documented in 11 (18%). The incidence of VF in the patients with J waves was significantly higher than that in those without J waves (38% vs 11%, p=0.026). J waves were observed in the inferior leads in 14 patients, lateral leads in 5, and anterior leads in 3. A univariate analysis indicated that the incidence of VF in the inferior leads of J wave positive patients (46%=6/14) was significantly (p=0.01) higher than that in the inferior leads of J wave negative patients (10%=5/48). The J waves in the anterior and/or lateral leads were not related to the incidence of VF. Notched type and slurred type J waves were not associated with VF. A multivariate analysis revealed that J waves in VSA patients were associated with VF [odds ratio (OR) 6.41, 95% confidence interval (CI) 1.37-29.93, p=0.02] and organic stenosis (OR 6.98, 95% CI 1.39-35.08, p=0.02). Further, J waves in the inferior leads were strongly correlated with VF (OR 11.85, 95% CI 2.05-68.42, p=0.006). The results suggest that the existence of J waves, especially in the inferior leads, might be a risk factor for VF in VSA patients. Copyright © 2016 Japanese College of Cardiology.

    Purpose We examined circulating miRNA expression profiles in plasma of patients with coronary artery disease (CAD) vs. matched controls, with the aim of identifying novel discriminating biomarkers of Stable (SA) and Unstable (UA) angina. Methods An exploratory analysis of plasmatic expression profile of 367 miRNAs was conducted in a group of SA and UA patients and control donors, using TaqMan microRNA Arrays. Screening confirmation and expression analysis were performed by qRT-PCR: all miRNAs found dysregulated were examined in the plasma of troponin-negative UA (n=19) and SA (n=34) patients and control subjects (n=20), matched for sex, age, and cardiovascular risk factors. In addition, the expression of 14 known CAD-associated miRNAs was also investigated. Results Out of 178 miRNAs consistently detected in plasma samples, 3 showed positive modulation by CAD when compared to controls: miR-337-5p, miR-433, and miR-485-3p. Further, miR-1, -122, -126, -133a, -133b, and miR-199a were positively modulated in both UA and SA patients, while miR-337-5p and miR-145 showed a positive modulation only in SA or UA patients, respectively. ROC curve analyses showed a good diagnostic potential (AUC ≥ 0.85) for miR-1, -126, and -483-5p in SA and for miR-1, -126, and -133a in UA patients vs. controls, respectively. No discriminating AUC values were observed comparing SA vs. UA patients. Hierarchical cluster analysis showed that the combination of miR-1, -133a, and -126 in UA and of miR-1, -126, and -485-3p in SA correctly classified patients vs. controls with an efficiency ≥ 87%. No combination of miRNAs was able to reliably discriminate patients with UA from patients with SA. Conclusions This work showed that specific plasmatic miRNA signatures have the potential to accurately discriminate patients with angiographically documented CAD from matched controls. We failed to identify a plasmatic miRNA expression pattern capable to differentiate SA from UA patients. PMID:24260372

    Full Text Available Background: As an acute phase protein, α1-antitrypsin (AAT has been extensively studied in acute coronary syndrome, but it is unclear whether a relationship exists between AAT and stable angina pectoris (SAP. The purpose of the present study was to investigate the association between AAT plasma levels and SAP. Methods: Overall, 103 SAP patients diagnosed by coronary angiography and clinical manifestations and 118 control subjects matched for age and gender were enrolled in this case-control study. Plasma levels of AAT, high-sensitivity C-reactive protein (hsCRP, lipid profiles and other clinical parameters were assayed for all participants. The severity of coronary lesions was evaluated based on the Gensini score (GS assessed by coronary angiography. Results: Positively correlated with the GS (r = 0.564, P < 0.001, the plasma AAT level in the SAP group was significantly higher than that in the control group (142.08 ± 19.61 mg/dl vs. 125.50 ± 19.67 mg/dl, P < 0.001. The plasma AAT level was an independent predictor for both SAP (odds ratio [OR] = 1.037, 95% confidence interval [CI]: 1.020-1.054, P < 0.001 and a high GS (OR = 1.087, 95% CI: 1.051-1.124, P < 0.001 in a multivariate logistic regression model. In the receiver operating characteristic curve analysis, plasma AAT level was found to have a larger area under the curve (AUC for predicting a high GS (AUC = 0.858, 95% CI: 0.788-0.929, P < 0.001 than that of hsCRP (AUC = 0.665, 95% CI: 0.557-0.773, P = 0.006; Z = 2.9363, P < 0.001, with an optimal cut-off value of 137.85 mg/dl (sensitivity: 94.3%, specificity: 68.2%. Conclusions: Plasma AAT levels correlate with both the presence and severity of coronary stenosis in patients with SAP, suggesting that it could be a potential predictive marker of severe stenosis in SAP patients.

    Objective: To define the characteristic of circadian rhythm of blood pressure in unstable angina pectoris (UAP)patients with hypertension and its effects on the cardiovascular events. Methods: It was a prospective study.Based on coronary angiographic results, 742 consecutive hospitalized UAP patients with hypertension and 89 consecutive hospitalized hypertensive patients were recruited between September 2014 and December 2015 in this study. Clinical data and the results of 24-hour ambulatory blood pressure monitoring (ABPM) were analyzed. Results: The total prevalence of hypertension in UAP is about 77.1%(742/962) in our cohort. The decrease of night-time systolic and diastolic blood pressure in UAP patients complicated with hypertension was lower than that in hypertensive patients ( P <0.05). The prevalence of dipper, non-dipper and reverse dipper pattern was 12.4%(92/742), 34.9%(259/742) and 52.7%(391/742) in UAP patients complicated with hypertension, 18.0%(16/89), 48.3%(43/89) and 33.7%(30/89) in hypertensive patients. Obviously, the abnormal circadian rhythm of blood pressure was more significant in UAP patients with hypertension than in hypertensive patients, characterized by higher reverse dipper pattern in UAP patients with hypertension compared to patients with hypertension( P =0.00), similar results were evidenced among the male and female patients and patients with various ages. Subgroup analysis showed that except similar results on the incidence of reverse dipper pattern in controlled blood pressure aged less than 45 years old, the incidence of reverse dipper pattern was all significantly higher in UAP patients complicating with hypertension than in hypertensive patients independent no matter blood pressure controlled or not (all P <0.05). After adjustment for sex, age, triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and other risk factors, binary logistic regression analysis showed that reverse dipper pattern

    Lidoflazine is a synthetic drug with calcium-channel blocking effects. In a 7-month study, 36 patients with stable angina pectoris were tested during a 3-month single-blind placebo phase. Nineteen were then randomized by double-blind methods to lidoflazine and 17 to placebo therapy. The lidoflazine group had a significant (p < 0.01) reduction in anginal attacks; the placebo group did not. Exercise testing demonstrated that lidoflazine therapy was associated with a 34% increase in total work performance and a 15.6% increase in peak calculated oxygen uptake during double-blind treatment (both p < 0.004 compared with the placebo group). Heart rate was significantly reduced at submaximal levels of exercise during lidoflazine therapy (p < 0.04). Nitroglycerin consumption and electrocardiographic changes at the end of exercise did not change during the double-blind phase. In a second study of six similar patients, single-blind administration of lidoflazine was associated with improved myocardial perfusion during exercise as determined by thallium-201 stress scintigraphy. These studies demonstrate that lidoflazine therapy is associated with relief of angina, an increased physical work capacity, and improved regional myocardial perfusion during exercise

    Coronary spasm plays an important role in the pathogenesis of coronary heart disease (CHD) and angina pectoris caused by coronary spasm or coronary spastic angina (CSA) is prevalent in Japan. However, the precise mechanisms underlying coronary spasm are unclear. Alcohol intolerance is prevalent among East Asians, and we previously reported that coronary spasm could be induced by alcohol intake in CSA patients. We herein examined whether CSA is associated with alcohol intolerance in Japanese subjects. The study subjects consisted of 80 CSA patients (57 men/ 23 women, mean age 62 ± 12) and 52 non-CSA patients (25 men/27 women, mean age 63 ± 10). The ethanol patch test (EPT) and questionnaire which evaluates flushing after ethanol intake, along with an examination of clinical features and laboratory chemistry data for CHD risk factors were done. Gender (male) and smoking were higher (p=0.007, and p=0.019, respectively) and plasma HDL cholesterol level was lower (p=0.035) in the CSA patients than in the non-CSA patients. Multivariable logistic regression analysis including age, EPT, smoking, and plasma HDL cholesterol level as independent variables revealed that positive EPT and smoking were significant predictors of CSA (p=0.011 and p=0.016, respectively). Positive EPT and alcohol flushing following alcohol intake, as well as smoking and plasma levels of HDL cholesterol, were significantly associated with CSA in Japanese patients. Therefore, alcohol ingestion as well as smoking is a significant risk factor for CSA in Japanese.

    High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice to assess cardiovascular risk. However, a correlation has not yet been established between the absolute levels of peripheral and central hs-CRP. To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable angina (UA). This observational, descriptive, and cross-sectional study was conducted at the Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD patients referred to the hospital for coronary angiography were evaluated. Forty patients with CAD (20 with SA and 20 with UA) were included in the study. Blood samples from LFPV and CS were collected before coronary angiography. Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001) and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p < 0.001). Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus CS in patients with SA and UA.

    Xuefu Zhuyu Capsule (XFZY) has been commonly used for relieving chest pain in patients with coronary heart disease (CHD). Randomized controlled trials (RCTs) on XFZY in treating unstable angina (UA) have not been systematically reviewed. This study aims to provide a PRISMA-compliant systematic review to evaluate the efficacy of XFZY in treating UA. An extensive search of 7 medical databases was performed up to June 2013. RCTs involving XFZY or combined with conventional drugs versus conventional drugs were identified. Meta-analysis was performed to evaluate the cardiovascular effects of XFZY. Rev Man 5.0 was used for data analysis. 8 RCTs were included in this review. Statistical analysis of the results showed that XFZY combined with conventional drugs had significant effect on relieving angina symptoms (RR: 1.26 [1.16, 1.38]; P<0.00001) and improving ECG (RR: 1.20 [1.04, 1.38]; P=0.01) compared with conventional drugs alone. No severe adverse events were reported. XFZY combined with conventional drugs appears to have potential cardiovascular effects in treatment of UA with few adverse events. However, further rigorous designed trials are still needed. Copyright © 2014. Published by Elsevier Ltd.

    This study aims to evaluate the safety and efficacy of Xuezhikang in the treatment of unstable angina pectoris (UAP) in patients with elevated liver enzymes caused by statins. Ninety UAP patients with elevated liver enzymes (higher than 3-fold the upper limits of normal caused by statins) were randomly divided into 3 groups: withdrawal of simvastatin (group A), continued taking of simvastatin (group B) and switching to Xuezhikang capsules (group C). Blood lipids and high-sensitivity C-reactive protein (hs-CRP) were measured before and after treatment, and liver enzymes were measured every two weeks. As the liver enzymes of the patients in group A returned to normal, they could again undertake administration of simvastatin. If the liver enzyme levels remained abnormal at four weeks, polyene phosphatidylcholine would be added. The endpoint events of each group were followed-up. After treatment for 4 weeks, the liver enzymes decreased in all of the three groups and there was a significant difference (p 0.05). The blood lipids and hs-CRP were both reduced in group B and C. The decreased triglyceride and hs-CRP levels and increased high-density lipoprotein cholesterol level in group C were more remarkable than those in group B (p Unstable angina pectoris; Xuezhikang capsules.

    To evaluate the feasibility of a double-acquisition coronary CT angiography (CCTA) protocol in the presence and absence of an intravenous (IV) vasodilator infusion for detecting vasospastic angina. Twenty patients with a high clinical probability of vasospastic angina were enrolled. All subjects underwent baseline CCTA without a vasodilator in the early morning followed by a catheterized coronary angiography with ergonovine provocation test. Within 3 days, all subjects underwent repeat CCTA during a continuous IV infusion of nitrate. Vasospastic angina as detected by CCTA was defined as significant stenosis (≥50 %) with negative remodelling without definite plaques or diffuse small diameter (<2 mm) of a major coronary artery with a beaded appearance on baseline CT that completely dilated on IV nitrate CT. The CCTA results were compared to the catheterized ergonovine provocation test as the reference standard. Among 20 patients, the catheterized ergonovine provocation test detected vasospasm in 15 patients. The sensitivity, specificity, positive predictive value and negative predictive value of CCTA in a per-patient-based analysis were 73, 100, 100 and 56 %, respectively. Double-acquisition CCTA in the presence and absence of IV infusion of nitrate allows noninvasive detection of vasospastic angina with moderate sensitivity and high specificity. (orig.)

    Full Text Available Introduction: Enhanced external counterpulsation (EECP is a noninvasive circulatory assist device that has been recently emerged as a treatment option for refractory angina or left ventricular (LV dysfunction. The aims of this study were to examine the effects of EECP on the elecrocardiographic parameters and the heart rate variability indices of patients with the coronary heart disease and function class II-III angina resistant to medication. Methods: In a descriptive study, the patients who presented with sever angina at function class II-III were studied. Those meeting the inclusion criteria were invited to participate and provided informed consent. The standard enhanced external counterpulsation treatment (35 one-hour procedures 5-6 times a week was done. Thirty minute ambulatory electrocardiographic monitoring and electrocardiogram before starting and at the end of treatment sessions were done. Data entry and analysis of data was done finally. Results: Twenty five patients with mean age 68±9 year including 21(84% men and 4(16% women were enrolled in this study. Electocardiogarphic parameters before and after treatment by EECP were not different statistically. Time domain indices of heart rate variability according to ambulatory monitoring findings were not changed significantly. Conclusion: Results of this study revealed that EECP did not improve the electrocardiographic and heart rate variability parameters of ischemic heart disease patients with refractory angina at function class II or III.

    Data remain limited regarding the comparative long-term mortality across the spectrum of patients with different indications for percutaneous coronary intervention (PCI). We evaluated early and late mortality in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI compared with early and late mortality in patients undergoing PCI for unstable angina (UA) or non-STEMI (NSTEMI) and stable angina. A total of 10,549 consecutive patients undergoing PCI from 1997 to 2005 at a single institution were followed up prospectively (median 3.2 years, interquartile range 1.5 to 5.6) to assess all-cause mortality. The indication for PCI was STEMI in 28%, UA/NSTEMI in 32%, and stable angina in 40%. The mortality rate at 6 years was 18.9% in patients with STEMI, 16.2% in patients with UA/NSTEMI, and 11.7% in those with stable angina. During the initial 6 months, patients with STEMI had an increased risk of death compared with patients with UA/NSTEMI (relative risk [RR] 3.09, 95% confidence interval [CI] 2.46 to 3.89) and stable angina (RR 5.82, 95% CI 4.45 to 7.62). However, between 6 months and 6 years, mortality accrued at an almost similar rate among patients with STEMI and those with stable angina (RR 1.06, 95% CI 0.86 to 1.32) and mortality was greatest in patients with UA/NSTEMI (UA/NSTEMI vs stable angina: RR 1.33, 95% CI 1.11 to 1.58; STEMI vs UA/NSTEMI: RR 0.80, 95% CI 0.65 to 0.99). In conclusion, we have demonstrated that the inferior survival rates in patients with STEMI after primary PCI are mainly attributed to greater mortality in the first months after the event. These observations highlight that new adjunctive therapeutic strategies should aim at mortality reduction in the first months after primary PCI.

    This study aimed to determine the quantitative low-flow threshold for stress-induced perfusion defects with severe angina and/or significant ST-segment depression during dipyridamole hyperemia. Vasodilator stress reveals differences in regional perfusion without ischemia in most patients. However, in patients with a perfusion defect, angina, and/or significant ST-segment depression during dipyridamole stress, quantitative absolute myocardial perfusion and coronary flow reserve (CFR) at the exact moment of definite ischemia have not been established. Defining these low-flow thresholds of angina or ST-segment changes may offer insight into physiological disease severity in patients with atherosclerosis. Patients underwent rest-dipyridamole stress positron emission tomography (PET) with absolute flow quantification in ml/min/g. Definite ischemia was defined as a new or worse perfusion defect during dipyridamole stress with significant ST-segment depression and/or severe angina requiring pharmacological treatment. Indeterminate clinical features required only 1 of these 3 abnormalities. The comparison group included patients without prior myocardial infarction, or angina or electrocardiographic changes after dipyridamole. In 1,674 sequential PET studies, we identified 194 (12%) with definite ischemia, 840 (50%) studies with no ischemia, and 301 (18%) that were clinically indeterminate. A vasodilator stress perfusion cutoff of 0.91 ml/min/g optimally separated definite from no ischemia with an area under the receiver-operator characteristic curve (AUC) of 0.98 and a CFR cutoff of 1.74 with an AUC = 0.91, reflecting excellent discrimination at the exact moment of definite ischemia. Thresholds of low myocardial vasodilator stress perfusion in ml/min/g and CFR sharply separate patients with angina or ST-segment change from those without these manifestations of ischemia during dipyridamole stress with excellent discrimination. Stress flow below 0.91 ml/min/g in dipyridamole

    Full Text Available Introduction & Objective: Several studies have been performed to evaluate correlation of serum high sensitivity CRP (hs-CRP level with the prognosis of the patients with diagnosis of unstable angina, and by now different results were reported. The aim of this study was to assess correlation between serum hs-CRP level and inhospital prognosis and cardiac events in the patients with unstable angina. Materials & Methods: This descriptive analytic study was performed from Sep 2004 till Feb 2006 in Shahid Beheshti hospital. Kermanshah, Iran. Sera were collected from 250 patients for hs-CRP measurement. Exclusion criteria were: acute ST elevation MI, non ST elevation MI, patients with history of recent infection, patients with recent trauma and patients with serum high sensitive CRP level more than 10 mg/lit. Patients were divided into two groups, first group whose serum hs-CRP level was less than 3 mg/lit and second group whose serum hs-CRP level was between 3 and 10 mg/lit. They were followed for recurrent chest pain, arrhythmias, pulmonary edema, acute myocardial infarction and in hospital death. Results were analyzed using x² and t-test. Results: Mean age were 57±7.8 and 58±11.5 years in first group and second group respectively. There was statistically significant difference in some cardiac complications such as dyspnea, duration of hospitalization, recurrent chest pain, CCU admission (p<0.001 and in hospital myocardial infarction (p=0.03, between two groups. Some complications did not have significant difference such as pulmonary edema, cardiogenic shock, arrhythmia, S3, S4 and pulmonary rates .There was no mortality in both groups. Conclusion: According to the results, we can use serum hs-CRP level for risk stratification in the patients with diagnosis of unstable angina. Obviously the patients with high serum hs-CRP level need more attention whether early invasive management help these patients, may be the matter of later studies.

    Long-chain fatty acid (LCFA) is the main energy source for normal myocardium at rest, but in ischemic myocardium, the main energy substrate shifts from LCFA to glucose. 123 I-BMIPP is a radiolabeled LCFA analog. In chronic stable angina without previous infarction, we suppose that reduced 123 I-BMIPP uptake is related to the substrate shift in myocardium with decreased myocardial flow reserve (MFR). The purpose of this study was to relate 123 I-BMIPP uptake to rest myocardial blood flow (MBF), hyperemic MBF, and MFR assessed with 15 O-water positron emission tomography (PET). We enrolled 21 patients with chronic stable angina without previous infarction, all of whom underwent 123 I-BMIPP single-photon emission computed tomography (SPECT) and 15 O-water PET. The left ventricle was divided into 13 segments. In each segment, rest MBF and hyperemic MBF were measured by PET. 123 I-BMIPP uptake was evaluated as follows: score 0=normal, 1=slightly decreased uptake, 2=moderately decreased uptake, 3=severely decreased uptake, and 4=complete defect. 123 I-BMIPP uptake was compared with rest MBF, hyperemic MBF, and MFR. The numbers of segments with 123 I-BMIPP scores 0, 1, 2, 3, and 4 were 178, 40, 25, 24, and 0, respectively. The rest MBFs for scores 0, 1, 2, and 3 were 0.93±0.25, 0.86±0.21, 0.97±0.30, and 0.99±0.37 ml/min/g, respectively. The hyperemic MBFs for scores 0, 1, 2, and 3 were 2.76±1.29, 1.84±0.74, 1.37±0.39, and 1.08±0.40 ml/min/g, respectively. The MFRs for scores 0, 1, 2, and 3 were 3.01±1.38, 2.20±0.95, 1.44±0.22, and 1.10±0.26, respectively. As 123 I-BMIPP uptake declined, hyperemic MBF and MFR decreased. In chronic stable angina without previous infarction, reduced 123 I-BMIPP uptake implies decreased MFR. (orig.)

    Long-chain fatty acid (LCFA) is the main energy source for normal myocardium at rest, but in ischemic myocardium, the main energy substrate shifts from LCFA to glucose. 123I-BMIPP is a radiolabeled LCFA analog. In chronic stable angina without previous infarction, we suppose that reduced 123I-BMIPP uptake is related to the substrate shift in myocardium with decreased myocardial flow reserve (MFR). The purpose of this study was to relate 123I-BMIPP uptake to rest myocardial blood flow (MBF), hyperemic MBF, and MFR assessed with 15O-water positron emission tomography (PET). We enrolled 21 patients with chronic stable angina without previous infarction, all of whom underwent 123I-BMIPP single-photon emission computed tomography (SPECT) and 15O-water PET. The left ventricle was divided into 13 segments. In each segment, rest MBF and hyperemic MBF were measured by PET. 123I-BMIPP uptake was evaluated as follows: score 0=normal, 1=slightly decreased uptake, 2=moderately decreased uptake, 3=severely decreased uptake, and 4=complete defect. 123I-BMIPP uptake was compared with rest MBF, hyperemic MBF, and MFR. The numbers of segments with 123I-BMIPP scores 0, 1, 2, 3, and 4 were 178, 40, 25, 24, and 0, respectively. The rest MBFs for scores 0, 1, 2, and 3 were 0.93+/-0.25, 0.86+/-0.21, 0.97+/-0.30, and 0.99+/-0.37 ml/min/g, respectively. The hyperemic MBFs for scores 0, 1, 2, and 3 were 2.76+/-1.29, 1.84+/-0.74, 1.37+/-0.39, and 1.08+/-0.40 ml/min/g, respectively.

    The potential importance of both prevention and personal responsibility in controlling heart disease, the leading cause of death in the USA and elsewhere, has attracted renewed attention. Coronary artery disease is preventable, using relatively simple and inexpensive lifestyle changes. The inexorable rise in the prevalence of obesity, diabetes, dyslipidemia, and hypertension, often in the risk cluster known as the metabolic syndrome, drives the ever-increasing incidence of heart disease. Population-wide improvements in personal health habits appear to be a fundamental, evidence based public health measure, yet numerous barriers prevent implementation. A common symptom in patients with coronary artery disease, classical angina refers to the typical chest pressure or discomfort that results when myocardial oxygen demand rises and coronary blood flow is reduced by fixed, atherosclerotic, obstructive lesions. Different forms of angina and diagnosis, with a short description of the significance of pain and silent ischemia, are discussed in this review. The well accepted concept of myocardial oxygen imbalance in the genesis of angina is presented with new data about clinical pathology of stable angina and acute coronary syndromes. The roles of stress electrocardiography and stress myocardial perfusion scintigraphic imaging are reviewed, along with the information these tests provide about risk and prognosis.

    Refractory angina constitutes a clinical problem. The aim of this study was to assess the safety and the feasibility of transendocardial injection of CD133(+) cells to foster angiogenesis in patients with refractory angina. In this randomized, double-blinded, multicenter controlled trial, eligible patients were treated with granulocyte colony-stimulating factor, underwent an apheresis and electromechanical mapping, and were randomized to receive treatment with CD133(+) cells or no treatment. The primary end point was the safety of transendocardial injection of CD133(+) cells, as measured by the occurrence of major adverse cardiac and cerebrovascular event at 6 months. Secondary end points analyzed the efficacy. Twenty-eight patients were included (n=19 treatment; n=9 control). At 6 months, 1 patient in each group had ventricular fibrillation and 1 patient in each group died. One patient (treatment group) had a cardiac tamponade during mapping. There were no significant differences between groups with respect to efficacy parameters; however, the comparison within groups showed a significant improvement in the number of angina episodes per month (median absolute difference, -8.5 [95% confidence interval, -15.0 to -4.0]) and in angina functional class in the treatment arm but not in the control group. At 6 months, only 1 simple-photon emission computed tomography (SPECT) parameter: summed score improved significantly in the treatment group at rest and at stress (median absolute difference, -1.0 [95% confidence interval, -1.9 to -0.1]) but not in the control arm. Our findings support feasibility and safety of transendocardial injection of CD133(+) cells in patients with refractory angina. The promising clinical results and favorable data observed in SPECT summed score may set up the basis to test the efficacy of cell therapy in a larger randomized trial. © 2014 American Heart Association, Inc.

    The inconsistent ability of novel biomarkers to predict acute kidney injury (AKI) across heterogeneous patients and illnesses limits integration into routine practice. We previously retrospectively validated the ability of the renal angina index (RAI) to risk-stratify patients and provide context for confirmatory serum biomarker testing for the prediction of severe AKI. We conducted this first prospective study of renal angina to determine whether the RAI on the day of admission (Day0) risk-stratified critically ill children for 'persistent, severe AKI' on Day 3 (Day3-AKI: KDIGO Stage 2-3) and whether incorporation of urinary biomarkers in the RAI model optimized AKI prediction. A total of 184 consecutive patients (52.7% male) were included. Day0 renal angina was present (RAI ≥8) in 60 (32.6%) patients and was associated with longer duration of mechanical ventilation (P = 0.04), higher number of organ failure days (P = 0.003) and increased mortality (P renal angina. Day3-AKI was present in 15/156 (9.6%) patients; 12/15 (80%) fulfilled Day0 renal angina. Incorporation of urinary biomarkers into the RAI model increased the specificity and positive likelihood, and demonstrated net reclassification improvement (P < 0.001) for the prediction of Day3-AKI. Inclusion of urinary neutrophil gelatinase-associated lipocalin increased the area under the curve receiver-operating characteristic of RAI for Day3-AKI from 0.80 [95% confidence interval (CI): 0.58, 1.00] to 0.97 (95% CI: 0.93, 1.00). We have now prospectively validated the RAI as a functional risk stratification methodology in a heterogeneous group of critically ill patients, providing context to direct measurement of novel urinary biomarkers and improving the prediction of severe persistent AKI. © The Author 2016.

    The long-term risk associated with different coronary artery disease (CAD) presentations in women undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is poorly characterized. We pooled patient-level data for women enrolled in 26 randomized clinical trials. Of 11,577 women included in the pooled database, 10,133 with known clinical presentation received a DES. Of them, 5,760 (57%) had stable angina pectoris (SAP), 3,594 (35%) had unstable angina pectoris (UAP) or non-ST-segment-elevation myocardial infarction (NSTEMI), and 779 (8%) had ST-segment-elevation myocardial infarction (STEMI) as clinical presentation. A stepwise increase in 3-year crude cumulative mortality was observed in the transition from SAP to STEMI (4.9% vs 6.1% vs 9.4%; p <0.01). Conversely, no differences in crude mortality rates were observed between 1 and 3 years across clinical presentations. After multivariable adjustment, STEMI was independently associated with greater risk of 3-year mortality (hazard ratio [HR] 3.45; 95% confidence interval [CI] 1.99 to 5.98; p <0.01), whereas no differences were observed between UAP or NSTEMI and SAP (HR 0.99; 95% CI 0.73 to 1.34; p = 0.94). In women with ACS, use of new-generation DES was associated with reduced risk of major adverse cardiac events (HR 0.58; 95% CI 0.34 to 0.98). The magnitude and direction of the effect with new-generation DES was uniform between women with or without ACS (pinteraction = 0.66). In conclusion, in women across the clinical spectrum of CAD, STEMI was associated with a greater risk of long-term mortality. Conversely, the adjusted risk of mortality between UAP or NSTEMI and SAP was similar. New-generation DESs provide improved long-term clinical outcomes irrespective of the clinical presentation in women. Published by Elsevier Inc.

    No data are available on the association of serum uric acid and vasospastic angina (VSA) which has endothelial dysfunction as a possible pathophysiologic mechanism. Low uric acid level might cause adverse outcomes in VSA in connection with endothelial dysfunction. We enrolled 818 VSA patients whose uric acid level was measured at admission. Patients were categorized according to tertiles of uric acid level: group I, ≤ 4.8 mg/dL; group II, 4.9-5.9 mg/dL; and group III, ≥ 6.0 mg/dL. Primary outcome was major adverse cardiac events (MACEs), defined as a composite of cardiac death, acute myocardial infarction (MI), ischemic stroke, coronary revascularization, and rehospitalization for angina. Median follow-up duration was 49.2 months. Median uric acid values were 4.1 mg/dL for group I, 5.4 mg/dL for group II, and 6.7 mg/dL for group III. In the overall population, group II had a significantly lower incidence of MACE compared to group I (47 [17.1%] vs. 66 [24.6%]; hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.02-2.26; P = 0.040) and a tendency of lower incidence of MACEs compared to Group III (47 [17.1%] vs. 62 [22.5%]; HR, 1.44; 95% CI, 0.98-2.13; P = 0.067).

    This study was performed to evaluate the presence of angina pectoris, electrocardiographic changes and reversible thallium-201 defects resulting from 2 different levels of exercise in 19 patients with known coronary artery disease and evidence of exercise-induced ischemia. The exercise protocols consisted of a symptom-limited incremental exercise test (Bruce protocol) followed within 3 to 14 days by a submaximal, steady-state exercise test performed at 70% of the maximal heart rate achieved during the Bruce protocol. The presence and time of onset of angina and electrocardiographic changes (greater than or equal to 0.1 mV ST-segment depression) as well as oxygen uptake, exercise duration and pressure-rate product were recorded. Thallium-201 (2.5 to 3.0 mCi) was injected during the last minute of exercise during both protocols, and the images were analyzed using both computer-assisted quantitation and visual interpretations. Incremental exercise resulted in anginal symptoms in 84% of patients, and electrocardiographic changes and reversible thallium-201 defects in all patients. In contrast, submaximal exercise produced anginal symptoms in only 26% (p less than 0.01) and electrocardiographic changes in only 47% (p less than 0.05), but resulted in thallium-201 defects in 89% of patients (p = not significant). The locations of the thallium-201 defects, when present, were not different between the 2 exercise protocols. These findings confirm the sequence of the ischemic cascade using 2 levels of exercise and demonstrate that the cascade theory is applicable during varying ischemic intensities in the same patient

    The iPOWER study aims at determining whether routine assessment of coronary microvascular dysfunction (CMD) in women with angina and no obstructive coronary artery disease is feasible and identifies women at risk. All women with angina referred to invasive angiographic assessment in Eastern Denmark are invited to join the study according to in- and exclusion criteria. Assessment includes demographic, clinical and psychosocial data, symptoms, electrocardiogram, blood- and urine samples and transthoracic echocardiography during rest and dipyridamol stress with measurement of coronary flow reserve (CFR) by Doppler of the left anterior descending artery. In substudies CMD will be assessed by positron emission tomography, peripheral endothelial function, magnetic resonance imaging-and computed tomography derived myocardial perfusion scans, angiographic corrected TIMI frame counts, advanced echocardiographic modalities at rest and during stress, and invasive measures of CFR and coronary vascular reactivity. The study will include 2000 women who will be followed for 5 years for cardiovascular outcomes. By May 2013, 1685 women have been screened, 759 eligible patients identified, 530 contacted, and 299 (56%) agreed to participate. Among the first 50 patients, Doppler CFR was successfully measured in 49 (98%). Among women with suspected ischemic heart disease and no obstructive coronary artery disease, non-invasive Doppler CFR is feasible as a routine assessment. The study will provide information on methods to diagnose CMD and determine the prognostic value of routine non-invasive assessment of microvascular function. Future study will provide women identified with CMD participation in interventional substudies designed to test treatment strategies. Copyright © 2014 Mosby, Inc. All rights reserved.

    Full Text Available Cardiac Syndrome X (CSX was considered a stable coronary syndrome, yet due to its nature, CSX symptoms often have a great impact on patients’ Quality of Life (QoL. According to ESC 2013 stable coronary artery disease criteria, CSX was replaced by Microvascular Angina (MA.Unfortunately, most CSX or MA patients, after classical angina (involving main coronary vessels has been ruled out, often do not receive proper treatment. Indications for pharmacological treatment of MA patients were introduced only recently.

In the presented article we have attempted to study the influence of cardiac rehabilitation (3 months programme on the QoL of patients recognized as suffering from MA, as well as to check if changes in myocardial perfusion in these patients at baseline and after completion of cardiac rehabilitation match changes in their QoL. Therefore, after screening 436 women for MA, we studied 55 of them who were confirmed as having MA and who agreed to participate in the study. Exercise tests, Myocardial Perfusion Imaging, and QoL questionnaires were studied at baseline and after completing 3 months period of cardiac rehabilitation. Results were subsequently compared, which showed a link between improved perfusion score in SPECT study and improved overall physical capacity, on one hand, and improved QoL score on the other. These results confirm that cardiac rehabilitation is a very useful treatment option for MA patients. It seems that training during cardiac rehabilitation is a very important factor (improved physical efficiency –> increase in self-belief, and that taking into consideration the multifactor pathophysiology of pain, it is connected with a better quality of life for MA patients.

    Full Text Available Cardiac Syndrome X (CSX was considered a stable coronary syndrome, yet due to its nature, CSX symptoms often have a great impact on patients’ Quality of Life (QoL. According to ESC 2013 stable coronary artery disease criteria, CSX was replaced by Microvascular Angina (MA.Unfortunately, most CSX or MA patients, after classical angina (involving main coronary vessels has been ruled out, often do not receive proper treatment. Indications for pharmacological treatment of MA patients were introduced only recently.

    The relationship of blood concentration of norepinephrine (NE), A-type (atrial) natriuretic peptide (ANP) and B-type (brain) natriuretic peptide (BNP) and {sup 123}I-metaiodobenzyl guanidine ({sup 123}I-MIBG) scintigraphy was examined in patients with heart failure. The patients were grouped as follows; 13 of dilated cardiomyopathy (DCM) group, 13 of hypertrophic cardiomyopathy (HCM) group and the 8 of stable effort angina. The control group was of 18 cases with normal {sup 201}TlCl (Tl) cardiac scintigraphy and chest pain. The blood was collected before the exercise tolerance by the ergometer, and the concentration of ANP, BNP and NE in blood was measured by the RIA method and the HPLC method, respectively. Patients were intravenously administrated 111Mbq of {sup 123}I-MIBG at rest and early images of the {sup 123}I-MIBG scintigraphy were taken after 15 min and late images after 3 hours. Washout rate (WR) and heart-mediastinal uptake rate (H/M) were obtained from late images. Compared with the control group, the DCM group showed the high levels of ANP and BNP (p<0.01) and the low level of NE (p=0.025). The HCM group showed the high level of BNP (p<0.001) and the low level in H/M. There were no differences in ANP, NE, H/M and WR between angina pectoris and the control. The correlations among BNP and H/M or WT were significant in all cases. BNP may be a remarkable index for sympathetic dysfunction. (K.H.)

    Diabetic patients are characterised by poorer prognosis and more cardiovascular complications compared with non-diabetic patients, which may be due to metabolic abnormalities and atherosclerotic plaque characteristics. Patients with unstable angina pectoris were enrolled in the study and divided into diabetes mellitus (DM) (patients, n=25; plaques, n=42) and non-DM (patients, n=53; plaques, n=65) groups according to their DM history. Optical coherence tomography (OCT) examinations were performed on all patients, and images were analysed by two independent investigators. Fibrous cap thickness was measured at the thinnest point of each plaque. The presence of plaque disruption, dissection, erosion, thrombosis and calcification were also noted. Calcified plaques in the DM group were significantly greater than those in the non-DM group (42.9% vs. 23.1%; p=0.03). Thin-cap fibroatheroma (TCFA) were detected, and no significant difference was found in the frequencies (42.9% vs. 52.3%; p=0.34) and fibrous cap thickness (57.08 ± 6.20 μm vs. 56.11 ± 9.23 μm, p=0.74) between the DM and non-DM groups. Thrombus and plaque erosion were similar in the two groups, but the frequency of dissection in the DM group was greater than that in the non-DM group (21.4% vs. 7.7%, p=0.04). The high sensitivity C-reactive protein between the two groups was similar (0.44 ± 0.20mg/dl vs. 0.46 ± 0.15 mg/dl, p=0.83). Higher calcification and dissection were detected in diabetic patients with unstable angina pectoris, and the difference in coronary plaque characteristics can explain the difference in clinical prognoses between DM and non-DM patients.

    The chemokine, fractalkine, independently enhances the vulnerability of coronary atherosclerotic plaques. The present study investigated the combined effects of CD36 and fractalkine on coronary plaque progression in patients with unstable angina pectoris. In the present study, 120 unstable angina pectoris patients undergoing coronary angiography and intravascular ultrasound were divided into two groups: an intermediate lesion group (lumen diameter stenosis 50-70%, 80 patients) and a severe lesion group (at least one lesion with lumen diameter stenosis > 70%, 40 patients). The control group consisted of 40 healthy age- and sex-matched subjects. Concentrations of CD36 and fractalkine were measured by enzyme-linked immunosorbent assay. Major adverse cardiovascular events were monitored over a 2-year follow up. Intravascular ultrasound showed that patients with severe lesions had more calcified and mixed plaques, and a larger plaque area and plaque burden than patients with intermediate lesions (P < 0.05-0.01). More patients with severe lesions underwent stent deployment (P < 0.05) than those with intermediate lesions. CD36 and fractalkine concentrations were significantly higher in the severe lesion patients (P < 0.05), and both had significant positive correlations (P < 0.05) with the plaque burden of atherosclerotic lesions. Using the matched nested case-control study, we found that CD36 and fractalkine levels were higher in patients with recurrent major adverse cardiovascular events than controls (P < 0.05). In conclusion, CD36 and fractalkine both promote, and might synergistically enhance, the progression of coronary atherosclerotic plaques. © 2014 Wiley Publishing Asia Pty Ltd.

    To conduct a systematic review of the evidence regarding the economic value of ranolazine relative to standard-of-care (SOC) for the treatment of symptomatic chronic stable angina (CSA). Electronic databases were searched using relevant keywords. The identified studies were independently reviewed by two investigators against pre-determined inclusion and exclusion criteria. Their data were extracted using a relevant form and consequently were synthesized. Studies were also evaluated using the Quality of Health Economic Studies scale. The main outcomes considered were the cost and effectiveness for each comparator and the incremental cost per quality-adjusted-life year (QALY) gained. Six studies were included in the review. Five of these assessed the cost-utility of ranolazine added to SOC, compared to SOC alone, using decision trees or Markov models whereas one was a retrospective cost evaluation study. The analysis was conducted from a payer perspective in five studies and from a societal perspective in one study with the time horizon varying between six months and a year. The incremental cost-effectiveness ratio (ICER), ranged from €4000 to €15,000 per QALY gained. Ranolazine appears to be dominant or cost-effective, mainly due to its ability to decrease angina-related hospitalizations and also due to a marginal improvement in quality of life. The acquisition cost of ranolazine was the variable with the greatest impact upon the ICER. The existing evidence, although limited, indicates that ranolazine may be a dominant or cost-effective therapy option, for the treatment of patients with symptomatic CSA. Further research is required to evaluate the cost-effectiveness of ranolazine. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    To conduct an economic evaluation comparing ranolazine as add-on therapy to standard-of-care (SoC) with SoC alone in patients with stable angina who did not respond adequately to first line therapy, in Greece. A decision tree model was locally adapted in the Greek setting to evaluate the cost-utility of ranolazine during a 6-month period. The analysis was conducted from a third-party payer perspective. The clinical inputs were extracted from the published literature. The cost inputs considered in the model reflect drug acquisition, hospitalizations, vascular interventions and monitoring of patients. The resource utilization data were obtained from 3 local experts. All costs refer to the year 2014. Cost-effectiveness was assessed by means of the incremental cost per quality adjusted life year (QALY) gained with the ranolazine as add-on therapy relative to SoC alone (ICER). Probabilistic sensitivity analysis (PSA) was performed. Ranolazine as add-on therapy was more costly compared to SoC alone, as the 6-month total cost per patient was €1170 and € 984, respectively. Patients received ranolazine plus SoC and SoC alone gained 0.3155 QALYs and 0.2752 QALYs, respectively. Ranolazine plus SoC resulted in an ICER equal to €4620 per QALY gained, well below the threshold of €34,000 per QALY gained. The PSA showed that the likelihood of ranolazine plus SoC being cost-effective at the threshold of €34,000 per QALY gained was 100 %. Τhe results suggest that ranolazine as add-on treatment may be a cost-effective alternative for the symptomatic treatment of patients with chronic stable angina in Greece.

    Examination of the action of donor NO (L-arginine) on platelet aggregation, endothelial function and exercise tolerance in patients with stable angina of effort (SAE). 42 patients with SAE (functional class I-II) and 10 healthy volunteers (control group) were assigned to two groups. 22 patients of group 1 were randomized to cross-over. They received cardiket (60 mg/day for 10 days or cardiket (60 mg/day) in combination with L-arginine (15 g/day for 10 days). 20 SAE patients of group 2 and control group received L-arginine (15 g/day for 10 days). In each group blood lipids were examined, and bicycle exercise test (BET) was performed. In addition, platelet aggregation and endothelial function were studied in group 2 and control group before and after the course of L-arginine. Compared to control group, endothelial function significantly improved in group 2 (from 5.0 +/- 2.9 to 7.8 +/- 4.1% vs 7.1 +/- 1.9 to 6.6 +/- 4.8%) (M +/- SD). BET duration increased in all the patients. After ADP addition in concentrations 1.5, 2.0, and 5.0 micromol/l platelet aggregation declined in 17 patients except 3 in whom the aggregation remained unchanged. Positive effect of L-arginine on endothelial function, exercise tolerance and platelet aggregation was observed in patients with stable angina of effort (functional class I-II). Therefore, arginine can be recommended as an adjuvant in the treatment of patients with ischemic heart disease.

The SalB plasma concentrations and Superoxide dismutase levels (PD index were recorded continuously at predetermined time interval after administration, and the related parameters were calculated by using WinNonlin software. The release profile of MPOPs was more sustained than that of IRPs. PK results indicated that the mean Cmax was significantly lower, the SalB plasma concentrations were steadier, both area under concentration-time curve from 0 to 24 h (AUC0–24 h and from 0 to infinity (AUC0–∞ were presented larger, and both the peak concentration time (Tmax and mean residence time (MRT were prolonged for MPOPs, as compared with those of IRPs. PD results suggested that peak drug effect (Emax was lower and the equilibration rate constant (ke0 between the central compartment and the effect compartment was higher of MPOPs vs. those of IRPs. PK–PD relationships demonstrated that the effect-concentration-time (ECT course of MPOPs was clockwise hysteresis loop, and that of IRPs was counter-clockwise hysteresis loop. Collectively, those results demonstrated that MPOPs were potential formulations in treating angina pectoris induced by atherosclerosis.

    baseline clinical characteristics who had undergone diagnostic coronary angiography for the first time were reviewed retrospectively. RESULTS: The frequency of significant CAD was significantly lower in COPD patients than in the control group (52.8% vs. 80.2%, p<0.001. Frequencies of CAD risk factors (older age, hypertension, diabetes, smoking history were significantly more frequent among COPD patients having significant CAD. Among patients reporting stable angina pectoris, significant CAD was detected in 32.7% of COPD patients and 71.0% of non-COPD patients (p<0.001. However, among the patients with a diagnosis of unstable angina pectoris, significant CAD was detected in 87.5% of COPD patients and 90.2% of non-COPD patients (p=0.755. CONCLUSION: Diagnosis of CAD in COPD patients by symptomatology may be difficult. However, clinical diagnosis of CAD in the setting of unstable angina is accurate in most of the COPD patients. Therefore, further noninvasive diagnostic methods or careful follow up may be more appropriate for COPD patients reporting stable angina pectoris.

    Calcium antagonists (Ca) have been effective in reducing angina attacks in patients with variant angina. However, there are no reports regarding the effectiveness of Ca on myocardial fatty acid metabolic images in patients with pure coronary spastic angina (CSA). This study sought to examine the correlation between myocardial fatty acid metabolic images and the medical treatment of Ca in patients with pure CSA. This study included 35 consecutive patients (28 men, mean age of 66±10 years) with angiographically confirmed coronary spasm and no fixed stenosis. Long-acting Ca was administered to all 35 patients. Isosorbide dinitrate/nicorandil/another Ca/beta-blocker were administered when chest pain was not controlled. Using an iodinated fatty acid analogue, 15-(p-[iodine-123]iodophenyl)-3-(R,S)methylpentadecanoic acid (BMIPP), myocardial scintigraphies with intravenous adenosine triphosphate infusion were performed before cardiac catheterization and 12 mo after medical therapy. According to the medical control states, these 35 patients were classified into 3 groups; response (disappearance of angina attacks, 12 pts, 60±11 years), partial response (angina attacks <4/mo, 12 pts, 67±10 years), and no response to therapy (angina attacks ≥4/mo, 11 pts, 71±6 years). Reduced BMIPP uptake was observed in 24 (69%) of 35 patients before the treatment. Reduced BMIPP uptake was also found in 18 patients (51%) after 12 mo. Normal BMIPP uptake after 12 mo therapy was observed in about half (response: 42%, partial response: 58%, no response: 45%) of patients among the 3 groups. There was no difference regarding the value of washout rate (WOR) (response; 10±7 (before), 14±8% (12 mo)), partial response; 11±7, 10±5%, no response; 13±9, 14±8%) among the 3 groups. The defect scores of BMIPP in the three groups were not different during at least one year medical therapy. No difference regarding the distribution of other medical therapies (angiotensin converting enzyme

    The benefit of CT coronary angiography (CTCA) in patients presenting with stable chest pain has not been systematically studied. We aimed to assess the effect of CTCA on the diagnosis, management, and outcome of patients referred to the cardiology clinic with suspected angina due to coronary heart disease. In this prospective open-label, parallel-group, multicentre trial, we recruited patients aged 18-75 years referred for the assessment of suspected angina due to coronary heart disease from 12 cardiology chest pain clinics across Scotland. We randomly assigned (1:1) participants to standard care plus CTCA or standard care alone. Randomisation was done with a web-based service to ensure allocation concealment. The primary endpoint was certainty of the diagnosis of angina secondary to coronary heart disease at 6 weeks. All analyses were intention to treat, and patients were analysed in the group they were allocated to, irrespective of compliance with scanning. This study is registered with ClinicalTrials.gov, number NCT01149590. Between Nov 18, 2010, and Sept 24, 2014, we randomly assigned 4146 (42%) of 9849 patients who had been referred for assessment of suspected angina due to coronary heart disease. 47% of participants had a baseline clinic diagnosis of coronary heart disease and 36% had angina due to coronary heart disease. At 6 weeks, CTCA reclassified the diagnosis of coronary heart disease in 558 (27%) patients and the diagnosis of angina due to coronary heart disease in 481 (23%) patients (standard care 22 [1%] and 23 [1%]; pcoronary heart disease increased (1·09, 1·02-1·17; p=0·0172), the certainty increased (1·79, 1·62-1·96; pcoronary heart disease. This changed planned investigations (15% vs 1%; pcoronary heart disease, CTCA clarifies the diagnosis, enables targeting of interventions, and might reduce the future risk of myocardial infarction.

    Full Text Available Richard KonesThe Cardiometabolic Research Institute, Houston, Texas 77054 USAAbstract: The potential importance of both prevention and personal responsibility in ­controlling heart disease, the leading cause of death in the USA and elsewhere, has attracted renewed ­attention. Coronary artery disease is preventable, using relatively simple and inexpensive lifestyle changes. The inexorable rise in the prevalence of obesity, diabetes, dyslipidemia, and ­hypertension, often in the risk cluster known as the metabolic syndrome, drives the ­ever-increasing incidence of heart disease. Population-wide improvements in personal health habits appear to be a fundamental, evidence based public health measure, yet numerous barriers prevent implementation. A common symptom in patients with coronary artery disease, classical angina refers to the typical chest pressure or discomfort that results when myocardial oxygen demand rises and coronary blood flow is reduced by fixed, atherosclerotic, obstructive lesions. Different forms of angina and diagnosis, with a short description of the significance of pain and silent ischemia, are discussed in this review. The well accepted concept of myocardial oxygen imbalance in the genesis of angina is presented with new data about clinical pathology of stable angina and acute coronary syndromes. The roles of stress electrocardiography and stress myocardial perfusion scintigraphic imaging are reviewed, along with the information these tests provide about risk and prognosis. Finally, the current status of gender disparities in heart disease is summarized. Enhanced risk stratification and identification of patients in whom procedures will meaningfully change management is an ongoing quest. Current guidelines emphasize efficient triage of patients with suspected coronary artery disease. Many experts believe the predictive value of current decision protocols for coronary artery disease still needs improvement in order to

    The clinical effect of intracoronary thrombus aspiration during percutaneous coronary intervention in patients with unstable angina pectoris is unknown. In this study, we aimed to assess how thrombus aspiration during percutaneous coronary intervention affects in-hospital and 30-month mortality and complications in patients with unstable angina pectoris.We undertook an observational cohort study of 645 consecutive unstable angina pectoris patients who had performed percutaneous coronary intervention from February 2011 to March 2013. Before intervention, 159 patients who had culprit lesion with thrombus were randomly assigned to group 1 (thrombus aspiration group) and group 2 (stand-alone percutaneous coronary intervention group). All patients were followed-up 30 months until August 2015.Thrombus aspiration was performed in 64 patients (46%) whose cardiac markers (ie, creatinine kinase [CK-MB] mass and troponin T) were significantly lower after percutaneous coronary intervention than in those of group 2 (CK-MB mass: 3.80 ± 1.11 vs 4.23 ± 0.89, P = 0.012; troponin T: 0.012 ± 0.014 vs 0.018 ± 0.008, P = 0.002). Left ventricular ejection fraction at 6, 12, and 24 months postintervention was significantly higher in the group 1. During a mean follow-up period of 28.87 ± 6.28 months, mortality rates were 6.3% in the group 1 versus 12.9% in the group 2. Thrombus aspiration was also associated with significantly less long-term mortality in unstable angina pectoris patients (adjusted HR: 4.61, 95% CI: 1.16-18.21, P = 0.029).Thrombus aspiration in the context of unstable angina pectoris is associated with a limited elevation in cardiac enzymes during intervention that minimises microembolization and significantly improves both of epicardial flow and myocardial perfusion, as shown by angiographic TIMI flow grade and frame count. Thrombus aspiration during percutaneous coronary intervention in unstable angina pectoris patients has better

Um Estado de direito que tudo abarque não poderia travar esta guerra, pois ele deveria tratar seus inimigos como pessoas e, conseqüentemente, não poderia tratá-las como fonte de perigo. Em Estados de direito que operam na prática de modo ótimo procede-se de outra maneira, e isso lhes dá a chance de não se quebrarem durante o ataque a seus inimigos.The preemptive punishment of terrorists and the use of harsh interrogation techniques are not within the classical standards of the Rule of Law. They belong rather to a state of exception. A State committed to all the usually accepted requirements of the Rule of Law would not be allowed to carry such a war, because it would have the duty to treat its enemies as persons. Therefore, it would not be authorized to treat them as a source of danger. Nevertheless, these classical standards have been challenged in the last two decades by major institutional changes that are now being discussed both in theoretical as in practical levels.

    In the management of ischemic heart disease, elderly patients constitute a subgroup that, despite having a worse prognosis, are usually managed more conservatively. The objective of this study was to evaluate if, in the management of unstable angina, a more conservative attitude in elderly patients is maintained after stratification by exercise test. The study population is constitude by 859 patients admitted to hospital due to suspected unstable angina that were referred to exercise test after medical stabilization. The management (invasive versus conservative, according to submission to cardiac catheterization or not) of patients was retrospectively studied, comparing patients 70 years-of age. Out of the 859 patients, 156 (18%) were > 70 years old, and the exercise test was positive in 281 (33%). Cardiac catheterization was performed in 494 (57%): 62% in older and 38% in younger patients (p management were: a negative exercise test, > 85% of the maximum heart rate, duration of exercise test more than 6 minutes, female gender, smoking and absence of episodes of rest angina. In the multivariate analysis, the statistically significant characteristics associated with an invasive management were the result of the exercise test (OR for positive result: 4.50; IC 95% = 2.73-7.63; p or = 6 minutes: 0.51; IC 95% = 0.29-0.88; p = 0.0177), the percentage of the maximum heart rate (OR for > or = 85%: 0.65; IC 95% = 0.42-0.98; p = 0.0391) and age (OR for > 70 years 0.36; IC 95% = 0.20-0.62; p = 0.0004). In the management of unstable angina, elderly patients constitute a more conservatively managed subgroup even after risk stratification with exercise test.

    Full Text Available Introduction. Rupture of vulnerable atherosclerotic plaques is the cause of most acute coronary syndromes (ACS. Postmortem studies which compared stable coronary lesions and atherosclerotic plaques in patients who have died because of ACS indicated high lipid-core content as one of the major determinants of plaque vulnerability. Objective. Our primary goal was to assess the potential relations of plaque composition determined by IVUS-VH (Intravascular Ultrasound - Virtual Histology in patients with stable angina and subjects in acute phase of ACS without ST segment elevation. Methods. The study comprised of 40 patients who underwent preintervention IVUS examination. Tissue maps were reconstructed from radio frequency data using IVUS-VH software. Results. We analyzed 53 lesions in 40 patients. Stable angina was diagnosed in 24 patients (29 lesions, while acute phase of ACS without ST elevation was diagnosed in 16 patients (24 lesions. In the patients in acute phase of ACS without ST segment elevation IVUS-VH examination showed a significantly larger area of the necrotic core at the site of minimal lumen area and a larger mean of the necrotic core volume in the entire lesion comparing to stable angina subjects (1.84±0.90 mm2 vs. 0.96±0.69 mm2; p<0.001 and 20.94±15.79 mm3 vs. 11.54±14.15 mm3; p<0.05 respectively. Conclusion. IVUS-VH detected that the necrotic core was significantly larger in atherosclerotic lesions in patients in acute phase of ACS without ST elevation comparing to the stable angina subjects and that it could be considered as a marker of plaque vulnerability.

    Full Text Available Abstract Background Decreased heart rate variability (HRV is related to higher morbidity and mortality. In this study we evaluated the linear and nonlinear indices of the HRV in stable angina patients submitted to coronary angiography. Methods We studied 77 unselected patients for elective coronary angiography, which were divided into two groups: coronary artery disease (CAD and non-CAD groups. For analysis of HRV indices, HRV was recorded beat by beat with the volunteers in the supine position for 40 minutes. We analyzed the linear indices in the time (SDNN [standard deviation of normal to normal], NN50 [total number of adjacent RR intervals with a difference of duration greater than 50ms] and RMSSD [root-mean square of differences] and frequency domains ultra-low frequency (ULF ≤ 0,003 Hz, very low frequency (VLF 0,003 – 0,04 Hz, low frequency (LF (0.04–0.15 Hz, and high frequency (HF (0.15–0.40 Hz as well as the ratio between LF and HF components (LF/HF. In relation to the nonlinear indices we evaluated SD1, SD2, SD1/SD2, approximate entropy (−ApEn, α1, α2, Lyapunov Exponent, Hurst Exponent, autocorrelation and dimension correlation. The definition of the cutoff point of the variables for predictive tests was obtained by the Receiver Operating Characteristic curve (ROC. The area under the ROC curve was calculated by the extended trapezoidal rule, assuming as relevant areas under the curve ≥ 0.650. Results Coronary arterial disease patients presented reduced values of SDNN, RMSSD, NN50, HF, SD1, SD2 and -ApEn. HF ≤ 66 ms2, RMSSD ≤ 23.9 ms, ApEn ≤−0.296 and NN50 ≤ 16 presented the best discriminatory power for the presence of significant coronary obstruction. Conclusion We suggest the use of Heart Rate Variability Analysis in linear and nonlinear domains, for prognostic purposes in patients with stable angina pectoris, in view of their overall impairment.

    Multislice computed tomography (CT) is an emerging technique for the non-invasive detection of coronary stenoses. While the diagnostic accuracy of 4-slice scanners was limited, 16-slice CT imagers showed promising results due to increased temporal and spatial resolution. These technical advances prompted us to evaluate the diagnostic performance of 64-slice CT coronary angiography in the detection of significant stenoses (defined as {>=} 50% luminal diameter reduction) versus invasive quantitative coronary angiography (QCA). Thirty-five patients with stable angina pectoris underwent CT coronary angiography performed with a 64-slice scanner (gantry rotation time 330 ms, individual detector width 0.6 mm) prior to conventional coronary angiography. Patients with heart rates >70 beats/min received 100 mg metoprolol orally. One hundred millilitres of contrast agent with an iodine concentration of 400 mgl/ml were injected at a rate of 5 ml/s into the antecubital vein. The CT scan was triggered with the bolus tracking technique. The sensitivity, specificity and the positive and negative predictive values of 64-slice CT were 99%, 96%, 78% and 99%, respectively, on a per-segment basis. The values obtained on a per-patient basis were 100%, 90%, 96% and 100%, respectively. When referral to catheterisation is questionable, CT coronary angiography may identify subjects with normal angiograms and consistently decrease the number of unnecessary invasive procedures.

    Left ventricular function during exercise and recovery was investigated in patients with angina pectoris, ST segment depression during exercise and angiographically normal coronary arteries (syndrome X) using a continuous left ventricular function monitor with cadmium telluride detector (CdTe-VEST). Fourteen patients with syndrome X and 14 patients with atypical chest pain without ST segment depression during exercise and normal coronary arteries (control group) performed supine ergometric exercise after administration of 740-925 MBq of technetium-99m labelled red blood cells, and left ventricular function was monitored every 20 s using CdTe-VEST. Left ventricular ejection fraction (EF) response was impaired (≤ 5% increase from rest to peak exercise) in 11 or 14 patients with syndrome X but in none of the control patients. Resting EF was similar in the two groups (62.1% ± 6.7% in patients with syndrome X, 61.9% ± 6.2% in controls); however, EF increase from rest to peak exercise was lower in syndrome X (-3.1 ± 9.5% vs 14.7% ± 7.4%). After cessation of exercise, all patients showed rapid EF increase over baseline and this EF overshoot was lower (19.3% ± 8.3% vs 26.4% ± 7.3%) with the time to EF overshoot longer (114 ± 43 s vs 74 ± 43 s, P < 0.05) in patients with syndrome X.

    Unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) is a common but heterogeneous disorder with patients exhibiting widely varying risks. Early risk stratification is at the center of the management program and can be achieved using clinical criteria and biomarkers, or a combination. In addition to anti-ischemic therapy and aspirin, the thienopyridine clopidogrel is indicated except in patients who are potential candidates for urgent coronary artery bypass grafting (CABG). Platelet glycoprotein (GP) IIb/IIIa antagonists are indicated in high-risk patients likely to undergo percutaneous coronary intervention (PCI) but are not indicated in the management of lower-risk patients who do not undergo PCI. There is a growing body of evidence to support the substitution of the low-molecular-weight heparin (LMWH) enoxaparin for unfractionated heparin (UFH). Three recent trials have demonstrated the benefit of an early invasive strategy with catheterization followed by revascularization in patients at high and intermediate risk. Lower-risk patients should undergo early noninvasive stress testing. An intensive program of secondary prevention is mandatory and should be begun before hospital discharge.

    The purpose of the study is approbation of the capabilities of high-resolution rhythmocardiography (RCG) for the determination of the actual cardiovascular status of operated patients with angina pectoris during coronary artery bypass graft surgery (CABGS) for myocardial revascularization. The research was done by means of a KAP-RK-02-Mikor hardware-software complex with a monitor record and the time- and frequency-domain analyses of heart rate variability (HRV). Monitor records were made at each stage of CABGS in 123 patients. As a result, HRV manifested itself as a fairly adequate and promising method for the determination of the cardiovascular status during CABGS. In addition, the data of the HRV study during CABGS testify to the capability of RCG to determine the high risk of life-threatening cardioarrhythmias before and during operation, to different changes in sinoatrial heart node (SN) dysregulation, and contain the HRV symptoms of a high death risk before, during and after shunting. The loss of the peripheral autonomic sympathetic and parasympathetic control in SN in the form of the autonomic cardioneuropathy syndrome is a predictor of the complications related to CABGS. The obtained data on RCG monitoring of HRV recording are suggestive of wide prospects of the high-resolution RCG method to be used in cardiac surgery as a whole. The actual multivariant dysregulations of SN pacemaker activity testify to its adequacy to the pathophysiology of each period of the cardiac operation, according to the initial ischemic damages and localization of cardiosurgical manipulations during CABGS.

    MicroRNAs (miRNAs) are involved in cardiac developmental and pathological processes, and serum profile is useful for identifying novel miRNAs. Serum samples were collected from unstable angina pectoris (UAP) and subclinical atherosclerotic (AS) patients. Solexa sequencing was used to predict novel miRNAs in 15 control individuals, 15 AS patients and 15 UAP patients. After bioinformatics analysis and filtering out in the newest version of miRbase (version 20.0), three novel miRNAs were validated in 80 control individuals, 80 AS patients and 80 UAP patients by quantitative reverse transcriptase polymerase chain reaction. Two of the three novel microRNAs (N1 and N3) were expressed at the highest levels in the AS group. N1 had an area under curve (AUC) of 0.811 (95% confidence interval 0.743-0.880) for AS. N3 showed a moderate separation with an area under curve (AUC) of 0.748 (95% confidence interval 0.664-0.833) for AS. Combined the two novel microRNAs can significantly distinguish AS from control. Three novel miRNAs were identified by Solexa sequencing and two of them may be new potential predictors for arthrosclerosis. Copyright © 2015 Elsevier Inc. All rights reserved.

    CT angiography (CTA) has prognostic value in patients. But it is unknown whether differences in atherosclerosis by CTA predict the development of unstable angina pectoris (UAP) vs. major adverse cardiac events (MACE). We followed patients undergoing CTA as part of their acute chest pain work-up. Primary outcome was the development of UAP or MACE (cardiac death, myocardial infarction, revascularization) during a minimum follow-up of 12-months. CTAs were assessed for extent and composition of coronary plaque and stenosis. Ordinal regression with a 3-level outcome (no events, UAP, MACE) was applied. Among 315 patients, 22 developed UAP and 31 MACE. While UAP patients had higher atherosclerosis burden with respect to all assessed features compared to patients with no events (p ≤ 0.02), only mixed plaque extent was significantly different between UAP and MACE patients (p=0.02). The odds ratio was 4.55 for being in a higher disease-level comparing patients with low extent to those with no mixed plaque, and 3.02 comparing patients with high to those with low. These findings remained after adjustments for potential confounders. The extent of mixed coronary plaque is different between patients who develop UAP vs. MACE, supporting the hypothesis that it is a more culprit morphology. Copyright © 2014 Elsevier Ireland Ltd.

    To study the correlation between thrombolysis in myocardial infarction (TIMI) risk stratification and blood stasis syndrome (BSS) score in patients with unstable angina pectoris (UAP), and to analyze the relation of BBS degree and UAP clinical outcomes. Collected were general data, demographic data, risk factors, Chinese medical symptoms and syndromes, coronary artery angiography results, relevant physical and chemical examinations from 114 UAP inpatients. Gensini score, TIMI risk score, and BSS score of these patients were calculated. The BBS score and Gensini score were significantly positively correlated (r = 0.78, P < 0.01). The BBS score was significantly higher in those with lesion in three branches than those with lesion in one branch or in two branches (P < 0.05). The BBS score was significantly higher in the high risk group than in the lower risk group and the medium risk group (P < 0.01). The TIMI risk score was obviously higher in the severe blood stasis group than in the moderate blood stasis group and the mild blood stasis group (P < 0. 05, P < 0.01). The BBS score and TIMI risk score was positively correlated (r = 0.23, P < 0.05). The BBS score was positively correlated with more coronary arteries involved. The more severe BBS degree, the TIMI risk score more higher, and the BBS degree more syndrome.

    To determine the clinical effectiveness and cost-effectiveness of enhanced external counterpulsation (EECP) compared with usual care and placebo for refractory stable angina and heart failure, and to undertake analyses of the expected value of information to assess the potential value of future research on EECP. Major electronic databases were searched between November 2007 and March 2008. A systematic review of the literature was undertaken and a decision model developed to compare EECP treatment with no treatment in adults with chronic stable angina. Five studies were included in the review. In the Multicenter Study of Enhanced External Counterpulsation (MUST-EECP), time to greater than or equal to 1-mm ST segment depression (exercise-induced ischaemia) was statistically significantly improved in the EECP group compared with the control group (sham EECP), mean difference (MD) 41 seconds [95% confidence interval (CI) 9.10-73.90]. However, there was no statistically significant difference between the EECP and control groups in the change in exercise duration from baseline to end of treatment, self-reported angina episodes or daily nitroglycerin use, and the clinical significance of the limited benefits was unclear. There was also a lack of data on long-term outcomes. There were more withdrawals due to adverse events in the EECP group than in the control group, as well as a greater proportion of patients with adverse events [relative risk (RR) 2.13, 95% CI 1.35-3.38]. The three non-randomised studies compared EECP with elective percutaneous coronary intervention (PCI) and usual care. There was a high risk of selection bias in all three studies and the results should be treated with considerable caution. The study comparing an EECP registry with a PCI registry reported similar 1-year all-cause mortality in both groups. In the Prospective Evaluation of EECP in Congestive Heart Failure (PEECH) trial, patients with heart failure were randomised to EECP or to usual care

    To study the preventative effects of Dongchongxiacao (Cordyceps) on contrast-induced nephropathy (CIN) in patients with stable angina pectoris (SAP). One-hundred and three SAP inpatients were divided randomly into two groups: basic treatment (n = 51) and Dongchongxiacao (Cordyceps) treatment (n = 52); corbrin capsules (3 g; t.d.s.) were used 3 days before angioplasty and 3 days after angioplasty). Serum creatinine (Scr) was assessed at the time of hospital admission and 1, 2, and 3 days after angioplasty. Values of kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL) and interleukin (IL) 18 in the kidney were detected before angioplasty and 1 day after angioplasty in the patients of both groups. The prevalence of CIN between the two groups was then compared. CIN occurred in 9 of 103 patients (8.74%). The prevalence of CIN in the Dongchongxiacao (Cordyceps) treatment group was lower than that of the basic treatment group (5.77% vs 11.76%) but the difference was not significant (P > 0.05). The post-procedure mean peak of Scr, post-procedure increase in Scr levels from baseline, and urine levels of KIM-1, NGAL and IL18 after the procedure in the Dongchongxiacao (Cordyceps) treatment group were significantly lower than those in the basic treatment group (P Cordyceps) in SAP patients who undergo coronary angiography or coronary intervention could prevent contrast-induced renal impairment.

    In patients with ST-segment elevation myocardial infarction (STEMI) pre-infarction angina, pre-procedural TIMI flow and collateral flow to the myocardium supplied by the infarct related artery are suggested to be cardioprotective. We evaluated the effect of these factors on myocardial salvage index (MSI) and infarct size adjusting for area at risk in patients with STEMI treated with primary percutaneous coronary intervention. Cardiac magnetic resonance (CMR) was used to measure myocardial area at risk within 1-7 days and final infarct size 90 ± 21 days after the STEMI in 200 patients. MSI was calculated as (area-at-risk infarct size) / area-at-risk. Patients with pre-infarction angina had a median MSI of 0.80 (IQR 0.67 to 0.86) versus 0.72 (0.61 to 0.80) in those without pre-infarction angina, P = 0.004). In a regression analysis of the infarct size plotted against the area-at-risk there was a strong trend that the line for the pre-infarction angina group was below the one for the non-angina group (P = 0.05). Patients with pre-procedural TIMI flow 0/1, 2 and 3 had a median MSI of (0.69 (IQR 0.59 to 0.76), 0.78 (0.68 to 0.86) and 0.85 (0.77 to 0.91), respectively (PCollateral flow did not change MSI (P = 0.45) nor area-at-risk (P = 0.40) and no significant difference in infarct size adjusted for area at risk (P = 0.25) was observed. Pre-infarction angina increases MSI in patients with STEMI supporting the theory that pre-infarction angina leads to ischemic preconditioning. As opposed to the presence of angiographically visible collateral flow to the infarct area pre-procedural TIMI flow is strongly associated with MSI.

    Full Text Available RESUMEN: El artículo examina algunos usos y abusos de la lengua inglesa en la actualidad en el contexto de la globalización. Se define la neolengua, se ofrecen similitudes de la misma en el lenguaje publicitario en España, se trazan sus orígenes y se apuntan algunos antecedentes en la historia de la literatura inglesa, al tiempo que se ilustran ejemplos de variantes contemporáneas de la misma bajo la denominación de «nukespeak», especialmente abundantes en el discurso de los conflictos bélicos. La lengua inglesa está indisociablemente unida a complejos factores de orden económico, tecnológico y cultural que afectan a su misma morfología. Por otra parte, la presencia ubicua de la lengua inglesa, como idioma global, opera sobre las estructuras de sentimiento, pensamiento y acción de los ciudadanos en todo el mundo. Para los profesionales de la enseñanza del idioma inglés, ello comporta la obligación de discernir y resistir sus efectos potencialmente perversos al tiempo que siguen promoviendo sus valiosos beneficios culturales.ABSTRACT: Contemporary uses and abuses of the English language are examined in the context of complex issues and globalization trends. The term «newspeak» is defined, similitudes of it are found today in the language of advertising in Spain, its origins are traced back and antecedents are located in the history of English literature, while the presence of new modalities of the Orwellian reductionist language, such as «nukespeak», is illustrated within the language of warfare. The English language is inextricably bound up with economical, technological and cultural factors which affect its very morphology just as much as the pervasive influence of English as a global language affects the structures of feeling, thought and action of citizens all over the world, which poses an obligation on the part of EFL teachers to discern and resist its ill effects while they promote its still highly valuable cultural

    Highlights: • Patients developing UAP had overall more atherosclerosis as patients without any events. • Patients developing MACE had only more mixed plaque as those developing UAP. • Different atherosclerotic plaque components by CTA carry different prognostic value. - Abstract: Objective: CT angiography (CTA) has prognostic value in patients. But it is unknown whether differences in atherosclerosis by CTA predict the development of unstable angina pectoris (UAP) vs. major adverse cardiac events (MACE). Methods: We followed patients undergoing CTA as part of their acute chest pain work-up. Primary outcome was the development of UAP or MACE (cardiac death, myocardial infarction, revascularization) during a minimum follow-up of 12-months. CTAs were assessed for extent and composition of coronary plaque and stenosis. Ordinal regression with a 3-level outcome (no events, UAP, MACE) was applied. Results: Among 315 patients, 22 developed UAP and 31 MACE. While UAP patients had higher atherosclerosis burden with respect to all assessed features compared to patients with no events (p ≤ 0.02), only mixed plaque extent was significantly different between UAP and MACE patients (p = 0.02). The odds ratio was 4.55 for being in a higher disease-level comparing patients with low extent to those with no mixed plaque, and 3.02 comparing patients with high to those with low. These findings remained after adjustments for potential confounders. Conclusion: The extent of mixed coronary plaque is different between patients who develop UAP vs. MACE, supporting the hypothesis that it is a more culprit morphology.

    Full Text Available Objective: In this study, we aimed to investigate whether platelet count and mean platelet volume (MPV could be new biomarkers addition to classical risk factors in premature coronary artery disease (CAD. Methods: Totally 124 male patients (mean age: 45.8±13.0 year; range of age: 27-78 year, with stable angina pectoris, were included. Clinical and laboratory findings (whole blood cell count, glucose, creatinine, lipid profile were recorded. Automatic blood counter was used for hematological parameters. Conventional coronary angiography was performed. Patients having acute coronary syndrome within the last six months, with severe valvular, structural or congenital heart disease, thyroid and hepatic dysfunction or signs of any infection were excluded. Results: The study population were separated into three groups by coronary angiography: 51 with stable CAD aged ≤40 years (premature CAD, 38 with stable CAD older than 40 (mature CAD and 35 with the normal coronary arteries (NCA. No significant difference was found in MPV values between premature CAD and mature CAD and also between premature CAD and NCA (p>0.05. A significant negative correlation was found between MPV and platelet count in premature CAD (r=-0.419, p=0.002. Both in premature CAD and mature CAD groups, higher MPV values was found in critical CAD subgroup than noncritical CAD subgroup, but the difference was not statistically significant (p>0.05. Conclusion: There was no significant difference in MPV between premature and mature male CAD patients compared to NCA group. A positive but non-significant correlation was found between the MPV values and the severity of CAD. J Clin Exp Invest 2014; 5 (3: 381-385

    It has been shown that dendritic cells (DCs) and fractalkine play a role in accelerating progression of the inflamed atherosclerotic lesions and plaque rupture. We evaluated the numbers and functional changes of DCs and its subsets in human type 2 diabetes with or without unstable angina pectoris (UAP). The study population consisted of 39 diabetic patients (DM:18 without CAD; DM + UAP: 21 with UAP), 18 non-diabetic UAP patients (UAP), and 15 healthy control (Normal). Peripheral blood DCs and its subsets were measured by three color flow cytometry. Serum levels of fractalkine, IL-12, and IFN-α were also measured. The functional status of the monocyte-derived DCs was analyzed by flow cytometry and allogeneic mixed T lymphocytes reaction. The percent and absolute numbers of DCs and mDC within the total leukocyte population was similar for Normal and DM, while significantly lower in DM + UAP. pDC numbers were not significantly altered. Serum fractalkine in DM + UAP was highest among the four groups (p = 0.04 vs. UAP, p = 0.0003 vs. DM, p < 0.0001 vs. Normal). Circulating mDC inversely correlated with serum fractalkine (r = -0.268, p = 0.01) level. Compared with DM and UAP, the costimulatory molecules CD86 and proliferation of T cells stimulated by DCs were significantly increased in DM + UAP group. Our study suggested that increases in the fractalkine level and the number and functional changes of blood DCs might contribute to diabetic coronary atherosclerosis and plaque destabilization.

    Serum uric acid (SUA) is the final product of purine metabolism in humans. The present study aimed to identify a potential association between serum UA and cardiac troponin I (cTnI) levels and to find out whether uric acid could differentiate patients presenting with the acute myocardial infarction (AMI) and unstable angina pectoris (UAP) in hyperuricemic and normouricemic acute coronary syndrome (ACS) patients. Eighty ACS patients, aged 50-83 years, were enrolled in the study, 40 of them presenting with AMI and 40 with UAP. Frequency of patients with serum uric level over threshold for hyperuricemia was investigated and two groups of patients were formed such as hyperuricemic and normouricemic groups (A and B groups, respectively) independently of type of ACS. Those groups of patients were also subjected to cTnI measurement. Levels of SUA are associated with the type of ACS in the hyperuricemic ACS patients (AMI versus UAP, 499(458-590), 425(400-447) mmol/L, p=0.007, respectively). Uric acid correlated significantly with cTnI, moderate positively in the group A (rho=0.358, p=0.038) and moderate negatively in the group B (r=-0.309, p=0.037) of ACS patients. Multiple logistic regression analysis revealed that cTnI and age were independently associated with the SUA levels in the group A of ACS patients. Serum uric acid differentiates AIM and UAP patients in hyperuricemic group of acute coronary syndrome. Therefore it can be used as nonspecific parameter for evaluation of the myocardial lesion extent only in hyperuricemic ACS patients. This is supported by finding that cTnI along with age predicts SUA level in hyperuricemic ACS patients.

    We evaluated the diagnostic value of resting echocardiographic findings including total heart calcification (THC) score in combination with dobutamine stress echocardiography (DSE) for detection of myocardial ischemia. Altogether, 110 patients with suspected angina pectoris underwent resting echocardiography and DSE. On the basis of resting echocardiography, we determined the THC score, left anterior descending artery diastole-to-systole velocity ratio (LAD-DSVR), and positive myocardial velocity during isovolumic relaxation phase (VIVR ) detected by color-coded tissue Doppler imaging. Myocardial ischemia was diagnosed by a 25% or greater reduction in the internal diameter of major coronary vessels with impaired fractional flow reserve (FFR ≤0.80). DSE had excellent specificity (89%) but modest sensitivity (52%) for wall-motion abnormality (WMA) analysis. Multivariate analysis showed that THC score ≥2 (odds ratio and 95% confidence interval: 4.49 [2.29-10.6]; P = 0.018), LAD-DSVR ≤1.5 (6.43 [1.39-20.3], P = 0.019), and duration of positive VIVR ≥71 msec (7.93 [3.72-12.1]; P < 0.001) were independent predictors of ischemia. The combination of inducible WMA and THC score yielded significantly higher sensitivity for ischemia detection than the inducible WMA alone (80% vs. 52%, P = 0.0008). Using receiver operating characteristics analyses, adding all three resting echocardiographic findings to clinical variables plus inducible WMA further improved prediction of ischemia (P = 0.028). Integration of DSE and resting echocardiographic findings describing degree of heart calcification, impaired LAD flow, and extent of delayed ejection motion of the myocardium improves detection of coronary angiogram-based FFR-guided ischemia. © 2015, Wiley Periodicals, Inc.

    The majority of women with angina-like chest pain have no obstructive coronary artery disease when evaluated with coronary angiography. Coronary microvascular dysfunction is a possible explanation and associated with a poor prognosis. This study evaluated the prevalence of coronary microvascular dysfunction and the association with symptoms, cardiovascular risk factors, psychosocial factors, and results from diagnostic stress testing. After screening 3568 women, 963 women with angina-like chest pain and a diagnostic coronary angiogram without significant coronary artery stenosis (<50%) were consecutively included. Mean age (SD) was 62.1 (9.7). Assessment included demographic and clinical data, blood samples, questionnaires, and transthoracic echocardiography during rest and high-dose dipyridamole (0.84 mg/kg) with measurement of coronary flow velocity reserve (CFVR) by Doppler examination of the left anterior descending coronary artery. CFVR was successfully measured in 919 (95%) women. Median (IQR) CFVR was 2.33 (1.98-2.76), and 241 (26%) had markedly impaired CFVR (<2). In multivariable regression analysis, predictors of impaired CFVR were age (P<0.01), hypertension (P=0.02), current smoking (P<0.01), elevated heart rate (P<0.01), and low high-density lipoprotein cholesterol (P=0.02), but these variables explained only a little of the CFVR variation (r(2)=0.09). CFVR was not associated with chest pain characteristics or results from diagnostic stress testing. Impaired CFVR was detected in a substantial proportion, which suggests that coronary microvascular dysfunction plays a role in the development of angina pectoris. CFVR was associated with few cardiovascular risk factors, suggesting that CFVR is an independent parameter in the risk evaluation of these women. Symptom characteristics and results from stress testing did not identify individuals with impaired CFVR. © 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley

    Comparative studies evaluating traditional versus newer antianginal (AA) medications in chronic stable angina pectoris (CSA) on cardiovascular (CV) outcomes and utilization are limited, particularly in patients with diabetes mellitus (DM). Claims data (2008 to 2012) were analyzed using a commercial database. Patients with CSA receiving a β blocker (BB), calcium channel blocker (CCB), long-acting nitrate (LAN), or ranolazine were identified and followed for 12 months after a change in AA therapy. Patients on traditional AA medications were required to have concurrent sublingual nitroglycerin. Therapy change was defined as adding or switching to another traditional AA medication or ranolazine to identify patients whose angina was inadequately controlled with previous therapy. Four groups were identified (BB, CCB, LAN, or ranolazine users) and matched on relevant characteristics. A DM subset was identified. Logistic regression compared revascularization at 30, 60, 90, 180, and 360 days. Negative binomial regression compared all-cause, CV-, and DM-related (in the DM cohort) health care utilization. A total of 8,008 patients were identified with 2,002 patients in each matched group. Majority were men (mean age 66 years). A subset of 3,724 patients with DM (BB, n = 933; CCB, n = 940; LAN, n = 937; and ranolazine, n = 914) resulted from this cohort. Compared to ranolazine in the overall cohort, traditional AA medication exhibited greater odds for revascularization and higher rates in all-cause outpatient, emergency room visits, inpatient length of stay, and CV-related emergency room visits. In the DM cohort, ranolazine demonstrated similar benefits over traditional AA medication. In conclusion, ranolazine use in patients with inadequately controlled chronic angina is associated with less revascularization and all-cause and CV-related health care utilization compared to traditional AA medication.

    This study investigated retardation of abnormal uptake of iodine-123-beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) scintigraphy in patients with vasospastic angina. Twenty-three patients with vasospastic angina showed abnormal uptake of BMIPP before medical treatment and had coronary vasospasm induced by acetylcholine. The patients were divided into two groups according to uptake of BMIPP after medical treatment: retardation of abnormal uptake of BMIPP (Group R, n=4) and normal uptake of BMIPP (Group N, n=19). Frequency of chest pain, medical treatment and autonomic nervous activity were compared between the two groups. Furthermore, the frequency of chest pain and uptake of BMIPP in group R were obtained after intensive medical treatment. Autonomic nervous activity was evaluated by heart rate variability on Holter electrocardiography. Heart rate variability contained high-frequency elements (HF; 0.15-0.4 Hz) and low-frequency elements (LF; 0.04-0.15 Hz). LF/HF was estimated for sympathetic nervous activity and HF was estimated for parasympathetic nervous activity. Daytime and nighttime autonomic nervous activity were compared between the two groups. The frequency of chest pain was higher in Group R than in Group N (p<0.05). Medical treatment was not different between the two groups. Circadian variation of sympathetic and parasympathetic nervous activity were absent in Group R. During the nighttime, Group R showed higher sympathetic nervous activity (p<0.05) and lower parasympathetic nervous activity (p<0.01) than Group N. The frequency of chest pain was significantly lower after intensive medical treatment (p<0.05), and uptake of BMIPP returned to normal in Group R. We suspected that the disorder in autonomic nervous activity was more severe in Group R, and thus induced coronary vasospasm. Retardation of abnormal uptake of BMIPP in patients with vasospastic angina indicates poor control of coronary vasospasm. Uptake of BMIPP is useful in the evaluation of

    Using a double-blind, crossover design, the comparative efficacy and safety of nifedipine and isosorbide dinitrate in the treatment of stable angina were studied in 34 patients. The study included a 2-week placebo washout period and two 6-week periods during which patients were randomized to either nifedipine or isosorbide dinitrate. The doses were titrated for each patient, and mean doses of the 2 drugs were comparable. A time-limited thallium treadmill test was performed at the end of each phase. Ischemic zone count rates were normalized to those of the nonischemic zone, and the change in this ratio with redistribution was calculated as reversible thallium defect. Two patients were discontinued from the study within 1 week after initiation of isosorbide dinitrate because of severe, intolerable headache. Two patients were withdrawn while receiving nifedipine: one had new congestive heart failure and the other had increasing angina. Of the remaining 30 patients who tolerated both drugs for at least 1 week, 4 patients from the isosorbide dinitrate group were either prematurely crossed over or discontinued from the study because of headache. One patient suffered headache from both drugs and was discontinued from the study. In the 30 patients, only nifedipine significantly reduced resting arterial pressure compared with baseline. Further, only nifedipine therapy resulted in significant decreases in the rate-pressure product and systolic pressure at a given workload. However, significant decreases in angina frequency, nitroglycerin consumption and exercise-induced maximum ST-segment depression and reversible thallium perfusion defect were produced by both nifedipine and isosorbide dinitrate

    Full Text Available Objective: To discuss the effect of Yixinkangtai Capsule combined with diltiazem on endothelial function, blood viscosity and lipid metabolism in patients with unstable angina pectoris. Methods: A total of 150 patients with unstable angina pectoris who were treated in the hospital between February 2014 and February 2017 were divided into the control group (n=75 and the research group (n=75 according to the random number table method. Control group received clinical conventional therapy, research group received Yixinkangtai Capsule combined with diltiazem therapy on the basis of conventional therapy, and both groups received 3 months of treatment. Differences in endothelial function, blood viscosity and lipid metabolism were compared between the two groups of patients before and after treatment. Results: Before treatment, the differences in serum levels of endothelial function indexes, blood viscosity indexes and lipid metabolism indexes were not statistically significant between the two groups. After 3 months of treatment, serum NO level of research group was higher than that of control group while ET-1 level was lower than that of control group; serum blood viscosity index TXB2 content of research group was lower than that of control group while PGI2 content was higher than that of control group; serum lipid metabolism indexes TG, TC and LDL-C contents of research group were lower than those of control group while HDL-C content was higher than that of control group. Conclusion: Yixinkangtai Capsule combined with diltiazem therapy can effectively optimize the endothelial function, reduce the blood viscosity and balance the lipid metabolism in patients with unstable angina pectoris.

The principal outcome measure was overall compliance measured electronically, whereas secondary outcome measures were drug effectiveness and health-related quality of life.Results: The overall compliance was 86.5 ± 21.3% in the betaxolol group versus 76.1 ± 26.3% in the metoprolol group (p < 0.01, and the correct number of doses was taken on 84.4 ± 21.6% and 64.0 ± 31.7% of treatment days, respectively (p < 0.0001. The percentage of missed doses was 14.5 ± 21.5% in the once-daily group and 24.8 ± 26.4% in the twice-daily group (p < 0.01. The percentage of doses taken in the correct time window (58.6% vs 42.0%, p = 0.01, correct interdose intervals (77.4% v 53.1%, p < 0.0001, and therapeutic coverage (85.6% vs 73.7%, p < 0.001 were significantly higher in the once-daily group. Both studied drugs had similar antianginal effectiveness. Health-related quality of life improved in both groups, but this increase was more pronounced in the betaxolol arm in some dimensions.Conclusions: The study demonstrates that patient compliance with once-daily betaxolol is significantly better than with twice daily metoprolol. Similarly, this treatment provides better quality of life. These results demonstrate possible therapeutic advantages of once-daily over twice-daily beta-blockers in the treatment of stable angina pectoris.Keywords: patient compliance, quality of life, stable angina pectoris, randomized controlled trial

    AIMS: To evaluate whether the corrected thrombolysis in myocardial infarction frame count (CTFC), an index of resting coronary blood flow, is associated with the risk of major adverse cardiovascular events (MACE) in patients with suspected stable angina pectoris (SAP) but no obstructive coronary......, fourth and fifth CTFC quintiles, respectively. Adjustment for cardiac risk factors including diabetes, active smoking, body mass index, and use of lipid-lowering and antihypertensive medication did not significantly change the results. CONCLUSIONS: In patients with SAP symptoms without obstructive CAD...
