Trombolisis coronaria sistémica en el infarto agudo del miocardio en pacientes del Hospital General Docente "Octavio de la Concepción y la Pedraja" / Thrombolysis in myocardial acute Infarction in patients of the General Teaching Hospital "Octavio de la Concepción y la Pedraja"

RESUMEN Introducción: En el Hospital General Docente "Octavio de la Concepción y la Pedraja" de Baracoa, provincia Guantánamo, Cuba, hasta la fecha no se ha caracterizado la prescripción de la trombolisis coronaria sistémica en el infarto agudo del miocardio. Objetivo: Caracterizar la prescripción de la trombolisis coronaria sistémica en el infarto agudo del miocardio en el citado hospital durante el trienio 2017-2019. Método: Se realizó un estudio descriptivo, retrospectivo, de corte transversal, del total de pacientes infartados en el periodo antes dicho (n=75). Se estudiaron las variables: edad, sexo, localización topográfica del infarto, tratamiento, evolución clínica, estado al egreso y causas de muerte. Resultados: El 72,0 % de los pacientes fueron hombres, el 37,3 % tenía 50 y 59 años de edad. La letalidad fue del 14,7 %. Fue más común el infarto anterior del ventrículo izquierdo (53,4 %). Se trombolizó el 28,0 %, pues en el 68,5 % la ventana isquémica fue superior a doce horas. La encefalopatía isquémica-hipóxica posparada cardiorrespiratoria secundaria a fibrilación ventricular (54,5 %) fue la causa directa de muerte más frecuente. Conclusiones: Fue insuficiente el porcentaje de pacientes tratados con trombolisis coronaria sistémica, sobre todo, por solicitar atención médica después de 12 horas del inicio de los síntomas.

ABSTRACT Introduction: In the General Teaching Hospital "Octavio de la Concepción y la Pedraja" of Baracoa, Guantánamo province, Cuba, the prescription of Thrombolysis in Myocardial Infarction (TIMI) has not been characterized so far. Objective: To charactirize the prescription of thrombolysis in myocardial infarction during the three-year period 2017-2019. Method: Of the total number of patients with heart attacks in the above-mentioned period (n=75) a descriptive, retrospective, cross-sectional study was carried out. Variables studied: age, sex, topographic location of the infarction, treatment, clinical evolution, state at discharge and causes of death. Results: 72.0 % of the patients were men, 37.3 % were 50 and 59 years old. The case fatality rate was 14.7%. Left ventricular infarction was the most common (53.4%) dysfunction. 28.0% of the patients received thrombolytic therapy, because in 68.5% of them, the ischemic was longer than twelve hours. Post-cardiorespiratory moderate ischemic-hypoxic encephalopathy with ventricular fibrillation (54.5%) was the most frequent direct cause of death. Conclusions: The patients´ rate treated with systemic coronary thrombolysis was insufficient, mainly due to the fact that they attend medical attention 12 hours after the onset of symptoms.

Prognostic value of deep medullary vein signs on magnetic sensitive weighted imaging in acute anterior circulation cerebral infarction / 中华神经医学杂志

Objective To investigate the correlations of distribution and grading of deep medullary veins (DMVs) with clinical prognoses of patients with acute anterior circulation infarction by using susceptibility-weighted imaging (SWI).Methods Fifty patients with acute anterior circulation infarction,admitted to our hospital from August 2016 to December 2017,were enrolled in our study.SWI was performed to evaluate the DMVs.Univariate and multivariate Logistic regression models were used to determine the correlation between distribution of DMVs and clinical prognoses of patients.DMVs on the ipsilateral side of the lesions were further graded and analyzed;boxplot was used to describe its relation with modified Rankin scale (mRS) scores of the patients.Results DMVs were observed in 36 patients (72％),with 19 ipsilateral DMVs and 17 contralateral DMVs.The ipsilateral DMVs were independently associated with poor outcome (odds ratio=3.380,95％CI:1.006-11.393,P=0.049).The contralateral DMVs were not independent predictors for outcomes,but appeared commonly in patients with good outcome (44.8％).In patients with ipsilateral DMVs,grading 1,grading 2,and grading 3 were noted in 7,two and three patients,respectively;boxplot analysis showed that DMVs patients of grading 3 had higher mRS scores,with an average of 4.Conclusion The ipsilateral DMVs on SWI are independent predictive biomarkers for poor clinical outcome after stroke,and contralateral DMVs often indicate good prognosis.

Efecto de las resinas secuestradoras de ácidos biliares en los desenlaces cardiovasculares y en los niveles séricos de lípidos: A systematic review / Effect of bile acid sequestrants on cardiovascular outcomes and seric lipids

Antecedentes: Las guías internacionales recientes proponen el uso de estatinas como piedra angular del manejo de la dislipidemia en adultos. Sin embargo, no se ha definido con claridad el tratamiento de los pacientes con intolerancia o efectos adversos asociados con estas. Las resinas secuestradoras de ácidos biliares son una alternativa interesante, pese a que la evidencia que avala su uso no ha sido evaluada cuidadosamente. Métodos: Se realizó una búsqueda de la literatura en MEDLINE, Embase y en la Biblioteca Cochrane hasta junio de 2013, acerca de artículos publicados en inglés y español, identificando experimentos clínicos aleatorizados y estudios de cohortes que evaluaran el impacto de las resinas secuestradoras de ácidos biliares en mortalidad, eventos cardiovasculares, niveles de lípidos séricos y efectos adversos. Se presenta la información de forma descriptiva. Resultados: Se identificaron cuatro experimentos clínicos aleatorizados y un estudio de cohortes, que incluían 6.833 pacientes. Solo uno de los estudios evaluó el impacto en la mortalidad cardiovascular, evidenciando que no hay diferencia estadísticamente significativa en comparación con placebo (RR de 0,76; IC 95% 0,5:1,15), aunque se observó una reducción del 16% en la incidencia de infarto agudo de miocardio (RR 0,84; IC 95% 0,67:1,00). Tres estudios evaluaron cambios en las fracciones lipídicas, los cuales mostraron disminución moderada en los niveles de colesterol LDL, sin percibir diferencias clínicamente significativas en los niveles de colesterol HDL y triglicéridos. Conclusión: La evidencia que respalda el uso de resinas secuestradoras de ácidos biliares es limitada y no avala su empleo como terapia de primera línea en pacientes con dislipidemia; no obstante, son una alternativa en pacientes con efectos adversos o intolerancia al manejo con estatinas.

Background: Recent international guidelines have proposed statins as the corner stone of dyslipidemia management in adults. However it is not clear if they are best option for patients with statin related intolerance or what their adverse effects are. The bile acid sequestrants are an interesting alternative, however its evidence has not been carefully evaluated. Methods: A search was conducted on MEDLINE, Embase and Cochrane library databases for articles published up to June 2013, limited to Spanish and English language. Randomized clinical trials (RCT) and cohort studies evaluating the impact of bile acid sequestrants on mortality, cardiovascular outcomes, seric lipids and adverse effects were selected. Information was presented in a descriptive way. Results: Four RCT and one cohort study with aggregate data on 6833 people were included. Just one study evaluated cardiovascular mortality showing no statistically significant difference when compared with placebo, (RR 0.76; 95% CI 0.5:1.15), however there was a 16% reduction on acute myocardial infarction incidence. (RR 0.84; 95% IC 0.67: 1.00). Three studies evaluated seric lipids changes showing a moderate reduction in LDL levels without clinical significant differences on HDL and triglyceride levels. Conclusions: The evidence supporting bile acid sequestrants use is lacking and not conclusive to recommend its use as first-line therapy in dyslipidemic patients; however, these are an alternative option for patients with statin-related intolerance or adverse effects.

Susceptibility Vessel Sign for the Detection of Hyperacute MCA Occlusion: Evaluation with Susceptibility-weighted MR Imaging

PURPOSE: Susceptibility vessel sign (SVS) on gradient echo image, which is caused by MR signal loss due to arterial thrombosis, has been reported in acute middle cerebral artery (MCA) infarction. However, the reported sensitivity and diagnostic accuracy of SVS have been variable. Susceptibility-weighted imaging (SWI) is a newly developed MR sequence. Recent studies have found that SWI may be useful in the field of cerebrovascular diseases, especially for detecting the presence of prominent veins, microbleeds and the SVS. The purpose of this study was to evaluate the diagnostic values of SWI for the detection of hyperacute MCA occlusion. MATERIALS AND METHODS: Sixty-nine patients (37 males, 32 females; 46-89 years old [mean, 69.1]) with acute stroke involving the MCA territory underwent MR imaging within 6 hours after the symptom onset. MR examination included T2, FLAIR (fluid-attenuated inversion recovery), DWI, SWI, PWI (perfusion-weighted imaging), contrast-enhanced MR angiography (MRA) and contrast-enhanced T1. Of these patients, 28 patients also underwent digital subtraction angiography (DSA) within 2 hours after MR examination. Presence or absence of SVS on SWI was assessed without knowledge of clinical, DSA and other MR imaging findings. RESULTS: On MRA or DSA, 34 patients (49.3%) showed MCA occlusion. Of these patients, SVS was detected in 30 (88.2%) on SWI. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of SWI were 88.2%, 97.1%, 96.8%, 89.5% and 92.8%, respectively. CONCLUSION: SWI was sensitive, specific and accurate for the detection of hyperacute MCA occlusion.

Criterios de Sgarbossa: ¿es momento de actualizarlos? / Sgarbossa criteria: is it time for an update?

El diagnóstico de infarto agudo de miocardio en presencia de bloqueo de rama izquierda constituye un reto y hasta ahora los criterios de Sgarbossa eran la única herramienta disponible a pesar de las limitaciones conocidas. Una nueva regla diagnóstica puede disminuir la incertidumbre y con ello mejorar la selección de pacientes candidatos a reperfusión temprana, aunque se requiere más investigación para validarla.

The diagnosis of acute myocardial infarction in presence of left bundle branch block is a challenging one, and so far Sgarbossa criteria are the only tool available despite the known limitations. A new diagnostic rule can reduce our diagnostic uncertainty and thereby improve patient selection candidates for an early reperfusion, but so far research is needed to validate.

Clinical Significance and Related Factors of Fluid-Attenuated Inversion Recovery Vascular Hyperintensi- ties in Transient Ischemic Attack / 中国神经精神疾病杂志

Objective To investigate clinical significance and related factors of fluid-attenuated inversion recov?ery vascular hyperintensities (FVH) in transient ischemic attack (TIA) of carotid system. Method Data including general information and TIA risk factors was continuously collected from 142 patients with carotid system TIA from the depart?ment of neurology of Sheng jing Hospital affiliated China Medical University from January 2012 to February 2014.All pa?tients completed brain MRI including FLAIR and diffusion-weighted imaging (DWI)and MRA examinations within 72 hours after TIA. All patients were followed up for one month. Risk factors and FVH situations were analyzed based on clinical manifestations and DWI results. Result There were 87 male cases (61.27%)and FVH positive 57 cases (40.14%) among 142 cases with carotid system TIA (mean age 63.2±11.5). Logistic regression analysis revealed that the large intra?cranial carotid artery stenosis≥50%(OR=2.44,95%CI:1.09~5.49, P=0.03) and prior history of ischemic stroke (OR=3.88,95%CI:1.04~14.5, P=0.04) were independently associated with positive FVH. At one month followed-up, 40 cas?es (28.17%) of 142 patients progressed to acute cerebral infarction. Vulnerable plaque number in the contralateral carot?id artery (P=0.018), contralateral intracranial large vessel stenosis in MRA≥50%(P=0.007) and contralateral FVH oc?currence rate (P=0.001) were significantly higher in cerebral infarction group than in non-cerebral infarction group. Con?clusion FVH is common in carotid TIA patients, which is associated with intracranial carotid artery stenosis ischemic and previous history of ischemic stroke. Vulnerable plaque number of contralateral carotid artery, contralateral intracranial large vessel stenosis≥50%and the rate of occurrence of contralateral FVH may be associated with short-term progress leading TIA to acute infarction.

Redes neuronales en el diagnóstico del infarto agudo de miocardio / Neural networks for the diagnosis of acute myocardial infarction

Introducción; El infarto agudo de miocardio representa la primera causa de muerte no trasmisible en el mundo. Una de las herramientas que sirven como soporte a las decisiones en su diagnóstico son las redes neuronales, de las cuales se ha demostrado un buen nivel de precisión. Métodos; Se realizó el entrenamiento y la prueba de varias redes neuronales, con diferentes arquitecturas para el diagnóstico del infarto, a partir de los datos de la escala de clasificación de la probabilidad de angina de Braunwald en un grupo de pacientes que ingresaron por dolor torácico al servicio de urgencias del Hospital San José de Bogotá. Resultados; Se generaron 40 redes que fueron probadas en 5 experimentos de los cuales se obtuvo mayor precisión diagnóstica con el modelo de 5 entradas electrocardiográficas más troponina, aunque el mejor valor predictivo negativo se alcanzó en el modelo con 10 variables clínicas, electrocardiográficas y troponina. Varias de las redes diseñadas tuvieron una sensibilidad y una especificidad del 100%. Se requiere un estudio de validación para comprobar estos hallazgos. Conclusiones; Con los resultados encontrados para las redes neuronales en la literatura y en este estudio se puede considerar el uso de esta estrategia de inteligencia computacional en la práctica.

Introduction; Myocardial infarction represents the leading cause of death by a noncommunicable disease worldwide; one of the tools that serve as decision support for establishing a diagnosis are neural networks. They have been shown to have a good level of accuracy. Methods; Training and testing of several neural networks was performed with different architectures for the diagnosis of the myocardial infarction in a group of patients admitted with chest pain emergency room in the Hospital de San José, Bogotá. This was carried out according to data from the incidence scale of Braunwald's classification of unstable angina. Results; Forty networks were generated and tested in five experiments obtaining an accurate diagnostic with the electrocardiographic pattern of five entries and troponin. The negative predictive value was 100% in the model with ten clinical variables, electrocardiogram and troponin. Some of the designed networks had a sensitivity and specificity of 100%. A validation study to verify these findings is required. Conclusions; With the results found for neural networks in the literature and in the present study, we should consider the practical use of this computational intelligence strategy in daily practice.

Influence of cover statement and clarity of messages upon risk decision making about thrombolysis therapy in patients with cerebral infarction / 中华行为医学与脑科学杂志

Objective Influence of cover statement and clarity of the messages upon risk decision making about thrombolysis therapy in patients with cerebral infarction was discussed in the Scenarios of thrombolytic therapy for acute cerebral infarction.Methods Inpatients and outpatients with cerebral infarction were randomly divided into two groups:detailed / simple cover statement group.Every participant underwent obscure messages and clear messages with only one frame:positive or negative frame.Results In the simple cover statement group,both obscure messages subgroup and clear messages subgroup were not influenced by the framing effect with preference to the risk seeking.In the detailed cover statement group,participants in the clear messages group were not influenced by the framing effect(x 2 =0.19,P＞0.05),while the subjects in the obscure messages group were actually affected by the framing effect,with the preference to risk seeking in the positive framework (x 2=7.90,P＜0.01).Conclusion The risk decision making about thrombolysis therapy in patients with cerebral infarction is influenced by cover statements and clarity of the messages.To improve the rate of thrombolysis therapy,the patients should be exposed to the obscure messages in the positive framing information under the detailed cover statement.

Comunicación interventricular post infarto agudo del miocardio / Post acute myocardial infarction interventricular communication

La comunicación interventricular es una de las complicaciones mecánicas posteriores al infarto agudo del miocardio que genera alta morbilidad y mortalidad. Luego del uso de trombolíticos esta complicación ha disminuido y ha hecho que esta entidad sea cada vez menos frecuente. En este artículo se expone el caso de un paciente con síndrome coronario agudo sin terapia de reperfusión inicial, con posterior ruptura del septum interventricular, en quien se evidenció la utilidad de la ecocardiografía en el diagnóstico de dicha entidad.

Interventricular communication is a one of the mechanical complications after acute myocardial infarction that generates high morbidity and mortality. After the use of thrombolytics this complication has decreased and has made it increasingly less frequent. This article presents the case of a patient with acute coronary syndrome without initial reperfusion therapy, with subsequent rupture of the interventricular septum, in whom the use of echocardiography in the diagnosis of this entity evidenced its usefulness.

INTRODUCTION: the acute myocardial infarction was over the 12 percent of deceased from ischemic heart disease in Venezuela in 2006 without evidence of decrease in mortality despite the technological improvement of emergences services. OBJECTIVE: to characterize its behavior in the integral diagnostic centers of the Vargas State from June, 2006 to June, 2009. METHODS: a retrospective and descriptive study was conducted to characterize the behavior of myocardial acute infarction in urgency and emergency services of integral diagnostic centers using the Barrio Adentro's Statistics. RESULTS: a total of 186 patients were seen due to myocardial acute infarction with predominance of intensive therapy admissions (2,4 percent) on the hospitalization services. Those deceased from this cause included 35 persons the 17,1 percent of total of deceased. The 39,2 percent was thrombolized where the higher figure was achieved in 2008 with a 51,2 percent. The mortality from myocardial acute infarction fluctuated between rates of 17,3 and 20 by each 100 patients treated. The crude mortality rate was of 9,58 by 100 000 inhabitants. CONCLUSIONS: the figure of cases seen due to infarction had a stable increasing behavior, accounting for the 0,7 percent of total of admissions in these centers with predominance of intensive therapy admissions over the hospitalization services. Thrombolytic treatment was applied using recombinant streptokinase in a significant percentage of patients. In the hospitalization services mortality from this cause was higher. The death risk not decreased for patients presenting with this disease and the general mortality during the study period was of 35 patients for a rate of 9,58 x 100 000 inhabitants

Different authors describe the results achieved in adhesion molecules study in this syndrome, its significance in diagnosis associated with conventional serum parameters and its therapeutical potential.

Acute cerebral infarction due to thrombus formation during GDC embolization for the treatment of intracranial aneurysm: A case report / 대한마취과학회지

Although Guglielmi Detachable Coil (GDC) endovascular treatment of intracranial aneurysms has become an alternative to surgery, the main complication continues to be thromboembolic events. In our patient, we found thrombus at the third branch of the right middle cerebral artery after coil embolization. We added intravenous heparin and gave abciximab, an antiplatelet agent through the catheter. We then elevated the blood pressure and administered intravenous colloid solution to maintain adequate collateral circulation. One day later, the patient presented with acute focal infartion in the right frontal lobe and we treated her with low molecular weight heparin. After seven days, the patient's symptoms disappeared, and there was no residual neurological deficit. Therefore, we believe potential clinical complications can be avoided through early recognition of thrombus and appropriate medical therapy. Furthermore, it is necessary to prevent hypotension and to maintain proper hematocrit levels during operations in patients having risk factors for thrombosis.

Three simple criteria in the diagnosis of myocardial infarction in the presence of left bundle-branch block: A two-year retrospective study at OMMC

The three criteria tested above either alone or in combination are highly specific markers of infarction that may help physicians rapidly diagnose and treat acute infarction in patients with left bundle-branch block. However, with these findings, conformation with enzyme studies is still required. There was no attempt to distinguish between previous and newly developed LBBB. Nonetheless, these criteria probably apply to both old and new LBBB. (Conclusions)
