ABSTRACT

Introducción: Las enfermedades Cerebrovasculares constituyen un importante problema de salud a escala global y en Cuba ocupan la tercera causa de muerte y la primera causa de discapacidad. Objetivo: Evaluar el uso de atorvastatina en el infarto cerebral aterotrombótico agudo. Métodos: Se realizó un estudio prospectivo longitudinal en los pacientes que acudieron al cuerpo de guardia del Hospital Clínico Quirúrgico Julio Trigo López diagnosticados como infarto cerebral aterotrombótico agudo. De forma aleatoria y con previo consentimiento informado se les suministró una dosis de 0, 20 mg o 40 mg de atorvastatina. Se les realizó tomografía axial computarizada de cráneo, la cual fue repetida al tercer día y a los 30 días. Se determinó el valor de proteína C reactiva en el cuerpo de guardia, y a los 30 días fueron evaluados clínicamente de acuerdo a la escala de National Institute of Health Stroke Scale en cuerpo de guardia, diariamente durante su ingreso y 30 días después. Resultados: El tamaño del área infartada disminuyó un 19,4 por ciento con 40 mg de atorvastatina al igual que el valor de proteína C reactiva que se redujo en 16 mg/L. La evaluación clínica según la escala de National Institute of Health Stroke Scale mostró una reducción en más de 8 puntos de acuerdo a la dosis de atorvastatina empleada. Conclusiones: Se demostró la eficacia de la atorvastatina por la disminución del área infartada, la reducción de los valores de proteína C reactiva y la evolución clínica favorable. Todos estos factores fueron directamente proporcional a la dosis de atorvastatina empleada(AU)


Introduction: Cererovascular diseases represent an important health problem worldwide and in Cuba they rank the third cause of death and the first cause of disability. Objective: To evaluate the use of astorvastin in acute atherotrombotic cerebral infactation. Methods: A longitudinal prospective study was carried out in patients who attended the emergency room of Julio Trigo López Surgical Clinical Hospital diagnosed with acute atherothrombotic cerebral infarction. Randomly and with prior informed consent, they were given a dose of 0, 20 mg or 40 mg of atorvastatin. Computerized axial tomography of the skull was performed, which was repeated on day 3 and day 30. The value of C-reactive protein in the emergency room was determined, and at day 30, they were clinically evaluated daily during admission and 30 days later, according to the scale of the National Institute of Health Stroke Scale in emergency room. Results: The size of the infarcted area decreased by 19.4 percent with 40 mg of atorvastatin, as well as the value of C-reactive protein, which decreased by 16 mg/L. The clinical evaluation according to the National Institute of Health Stroke Scale showed reduction of more than 8 points according to the dose of atorvastatin used. Conclusions: The efficacy of atorvastatin was demonstrated by the reduction of the infarcted area, the reduction of C-reactive protein values and the favorable clinical evolution. All of these factors were directly proportional to the dose of atorvastatin used(AU)

ABSTRACT

Introducción: La mayoría de los infartos cerebrales aterotrombóticos son debidos a aterosclerosis extracraneal y a los factores de riesgo que lo condicionan. Objetivo: Caracterizar a pacientes con ictus aterotrombótico de territorio anterior según tamaño, sexo y factores de riesgo aterotrombótico. Métodos: Se realizó un estudio transversal a 63 pacientes que acudieron al Hospital Militar Central "Dr. Carlos J. Finlay" con diagnóstico de infarto cerebral aterotrombótico reciente de territorio carotídeo, a los que se les realizó tomografía de cráneo simple, entre los años 2011 y 2013. Resultados: Predominaron los infartos grandes (57,1 por ciento) en hombres (80,6 por ciento) y de forma general también fue el sexo masculino el más afectado (68,3 por ciento). La mayoría de los pacientes que tuvieron tanto infartos medianos (59,3 por ciento) como infartos grandes (58,3 por ciento), refirieron de 3 a 4 factores de riesgo aterotrombótico (58,7 por ciento). Prevaleció la hipertensión arterial (82,5 por ciento), con mayor coincidencia con los infartos medianos (88,9 por ciento), que con los infartos grandes (77,8 por ciento). Conclusiones: El ictus aterotrombótico reciente de territorio de irrigación carotídeo se caracterizó en esta serie, por infartos grandes y mayor afectación de adultos mayores, hipertensos, del sexo masculino. La existencia de 3 a 4 factores de riesgo en cada paciente prevalece tanto en los que presentan infarto cerebral mediano como grande(AU)


Introduction: Most of atherothrombotic cerebral infarctions are due to extracranial atherosclerosis and the risk factors that condition it. Objective: To characterize patients with atherothrombotic stroke of the anterior territory according to size, sex and atherothrombotic risk factors. Method: A cross-sectional study was performed on 63 patients attended at the "Dr. Carlos J. Finlay" hospital with a diagnosis of recent atherothrombotic cerebral infarction of the carotid territory, who underwent simple skull tomography, between 2011 and 2013. Results: Large infarcts predominated (57.1 percent) in men (80.6 percent) and in general, male sex was also the most affected (68.3 percent). Most of patients who had both moderate infarcts (59.3 percent) and large infarcts (58.3 percent), reported 3 to 4 atherothrombotic risk factors (58.7 percent). Prevalence of arterial hypertension (82.5 percent), with greater coincidence with medium infarcts (88.9 percent), than with large infarcts (77.8 percent). Conclusions: The recent atherothrombotic stroke of the carotid irrigation area was characterized in this series, due to large infarcts and greater involvement of elderly, hypertensive males. The existence of 3 to 4 risk factors in each patient prevails both in those with medium cerebral infarction and large ones(AU)

ABSTRACT

Introducción: El eco-Doppler carotídeo es la prueba de elección en el estudio inicial y de seguimiento del ictus aterotrombótico. Objetivo: Describir los hallazgos ecográficos en ambos ejes carotídeos en pacientes con infarto cerebral aterotrombótico del territorio vascular homónimo. Métodos: Se realizó una investigación observacional con todos los pacientes (63), que acudieron al Hospital Militar Central "Dr. Carlos J. Finlay", entre octubre del 2012 y septiembre del 2013, con diagnóstico clínico y tomográfico de infarto cerebral aterotrombótico de territorio anterior, a los que se les realizó eco-Doppler carotídeo. Resultados: Se contabilizaron mayor cantidad de placas de ateromas en el eje carotídeo homolateral al ictus aterotrombótico (54,3 por ciento) y la gran mayoría de estos fueron inestables (98,4 por ciento). La placa tipo III (50 por ciento), la irregularidad del contorno (54,1 por ciento) y la estenosis menor del 49 por ciento (57,6 por ciento) fueron los hallazgos ecográficos que dominaron en el eje contralateral al infarto. En ambas carótidas también fueron las placas tipo III (47,1 por ciento), la irregularidad de los contornos (51,6 por ciento), las estenosis no significativas (54,3 por ciento) y la inestabilidad de estas (94,4 por ciento), las que predominaron. Conclusiones: La aterosclerosis carotídea en el ictus aterotrombótico describe mayoritariamente placas tipo III irregulares, que provocan estenosis menores del 49 por ciento en ambos ejes carotídeos y la inestabilidad es casi constante, con una incidencia ligeramente mayor en el eje carotídeo homolateral al infarto. La frecuencia del resto de las cualidades de las placas de ateromas enunciadas, domina levemente en el eje carotídeo contralateral(AU)


Introduction: Carotid echo-Doppler is the test of choice in the initial and follow-up study of atherothrombotic stroke. Objective: To describe echographic findings in both carotid axes in patients with atherothrombotic cerebral infarction of the homonymous vascular territory. Methods: Sixty-three patients underwent an observational and cross-sectional investigation at Dr. Carlos J. Finlay Central Military Hospital from October 2012 to September 2013. They have a clinical and tomographic diagnosis of atherothrombotic cerebral infarct from the previous territory and the underwent a carotid echo-Doppler. Results: We recorded higher number of atheromatous plaques in the homolateral carotid axis at atherothrombotic stroke (54.3 percent) and the majority was unstable (98.4 percent). Type III plate (50 percent), irregularity of the contour (54.1 percent) and less than 49 percent stenosis (57.6 percent) were the echographic findings that dominated the axis contralateral to the infarction. In both carotids, type III plaques (47.1 percent), irregularity of the contours (51.6 percent), non-significant stenosis (54.3 percent) and instability (94.4 percent) predominated. Conclusions: Carotid atherosclerosis in atherothrombotic stroke mostly describes the presence of irregular, type III plaques that cause stenosis of less than 49 percent in both carotid axes. The instability of them is almost constant, with a slightly higher incidence in the homolateral carotid axis to infarction. The frequency of the rest of the qualities of the listed atheromatous plaques slightly dominates in the contralateral carotid axis(AU)

ABSTRACT

Aims and objectives: The present study makes a comparative analysis between the clinical profile of lacunar infarcts (LI) and that of atherothrombotic brain infarcts (ABI). Methods: Hospital-based descriptive study of 1809 consecutive patients admitted over a period of 24 years with a diagnosis of lacunar cerebral infarction (n = 864) or atherothrombotic cerebral infarction (n = 945). A comparative analysis of the demographic data, cerebral vascular risk factors, clinical data and hospital evolution between both subtypes of cerebral infarction was performed using a univariate and multivariate statistical methodology. Results: LI accounted for 26.5% and ABI for 28.9% of all cerebral infarctions in the registry. The variables directly and independently associated with ABI were: ischemic heart disease, previous transient ischemic attack, previous cerebral infarction, peripheral vascular disease, anticoagulant therapy, age > 85 years, vegetative symptoms, decreased level of consciousness, sensory deficit, visual deficit, speech disorders, and neurological, respiratory and urinary complications during hospital admission. In contrast, the absence of neurological symptoms at hospital discharge was directly associated with LI. Conclusions: LI and ABI have a distinct clinical profile. The best functional prognosis of LI during the acute phase of the disease is characteristic. In contrast, ICAs have a higher atherosclerotic burden and a worse prognosis.


Fundamentos y objetivo: El objetivo del estudio es efectuar un análisis comparativo entre el perfil clínico de los infartos lacunares (IL) y el perfil de los infartos cerebrales aterotrombóticos (ICA). Métodos: Estudio hospitalario descriptivo de 1809 pacientes consecutivos ingresados durante un período de 24 años con el diagnóstico de infarto cerebral de tipo lacunar (n = 864) o por infarto cerebral aterotrombótico (ICA) (n = 945). Se realizó un análisis comparativo de los datos demográficos, factores de riesgo vascular cerebral, datos clínicos y de evolución hospitalaria utilizando una metodología estadística univariada y, posteriormente, multivariada. Resultados: Los IL representaron el 26.5% y los ICA el 28.9% del total de infartos cerebrales del registro. Las variables asociadas directamente y de forma independiente con los ICA fueron: cardiopatía isquémica, ataque isquémico transitorio previo, infarto cerebral previo, enfermedad vascular periférica, uso de anticoagulantes, edad > 85 años, síntomas vegetativos, disminución del nivel de conciencia, déficit sensitivo, déficit visual, trastornos del habla y complicaciones neurológicas, respiratorias y urinarias durante el ingreso hospitalario. En cambio, la ausencia de sintomatología neurológica al alta se asoció directamente con los IL. Conclusiones: Los IL y los ICA tienen un perfil clínico diferenciado. Es característico el mejor pronóstico funcional de los IL durante la fase aguda de la enfermedad. En cambio, los ICA presentan mayor carga aterosclerótica y peor pronóstico evolutivo.

Métodos: estudio explicativo, analítico, caso/control. El grupo de casos fue de 226 pacientes con diagnóstico de enfermedad cerebrovascular aterotrombótica, ingresados en la Sala de Ictus del Hospital General Docente Enrique Cabrera entre 2014-2016 y el grupo control de 226 sin enfermedad cerebrovascular. Se formaron dos grupos, uno con presión de pulso 60 mmhg y otro con presión de pulso < 60 mmHg en pacientes hipertensos y no hipertensos. Resultados: la media de la edad fue de 69,65 años y el 61,45 por ciento eran masculinos; la frecuencia de hipertensión arterial fue de 70,4 por ciento y la de fumadores, 35,4 por ciento y con PP≥ 60 mmHg, 62,0 por ciento. La asociación de la presión de pulso 60 mmHg con enfermedad cerebrovascular aterotrombótica en pacientes hipertensos resultó significativa con odds-ratio 4,72, Intervalo de Confianza 95 por ciento(2,79-7,98) y en pacientes no hipertensos también resultó significativa con odds-ratio 6,86 Intervalo de Confianza 95 por ciento (3,33-14,07). El riesgo atribuible en expuestos fue de 88,6 por ciento y el riesgo atribuible en la población de 50,4 por ciento. Conclusiones: la presión de pulso se asoció de forma significativa a la enfermedad cerebrovascular aterotrombótica en pacientes hipertensos y no hipertensos(AU)


Introduction: Pulse pressure is an important marker or predictor of risk for acute atherosclerotic complications, including cerebrovascular disease. Objectives: To determine the relationship between pulse pressure and atherothrombotic cerebrovascular disease in hypertensive and nonhypertensive patients. Methods: Explanatory, analytical, case control study. The case group consisted of 226 patients diagnosed with atherothrombotic cerebrovascular disease admitted to the Ictus Room at Enrique Cabrera General Teaching Hospital between 2014 and 2016, and the control group consisted of 226 patients without cerebrovascular disease. Two groups were formed, one with a pulse pressure higher than or equal to 60 mmHg and one with a pulse pressure under 60 mmHg in hypertensive and nonhypertensive patients. Results: Mean age was 69.65 years and 61.45 percent were male. The frequency of hypertension was 70.4 percent and that of smokers was 35.4 percent, and with PP≥60 mmHg, which represented 62.0 percent. The association of pulse pressure higher than or equal to 60 mmHg with atherothrombotic cerebrovascular disease in hypertensive patients was significant with odds ratio of 4.72, and confidence interval of 95 percent (2.79-7.98), while in nonhypertensive patients it was also significant with odd ratios of 6.86, and confidence interval of 95 percent CI (3.33-14.07). The attributable risk in exposed people was 88.6 percent and the attributable risk in the population was 50.4 percent. Conclusions: Pulse pressure was significantly associated with atherothrombotic cerebrovascular disease in both hypertensive and nonhypertensive patients(AU)

ABSTRACT

Introducción: los datos de mortalidad son base para una amplia gama de indicadores de diversa complejidad. No solo representan las herramientas para evaluar el riesgo de muerte en una población y la repercusión de las enfermedades en la salud, sino también la gravedad de las enfermedades y la sobrevivencia experimentada por la población. Objetivo: estimar la mortalidad y los años de vida potenciales perdidos por enfermedades aterotrombóticas en el municipio Cerro. Métodos: se realizó un estudio observacional, descriptivo, retrospectivo de las defunciones por enfermedades aterotrombóticas en el municipio Cerro en el período comprendido entre el 2000 y el 2006 y se analizaron por edad, sexo, sitio y causa de defunción. Para el análisis estadístico se procedió al cálculo de las tasas brutas y tipificadas de mortalidad y por años de vida potenciales perdidos por mortalidad. Resultados: se observó una tendencia a la disminución de la mortalidad y un aumento en los años de vida potenciales perdidos a lo largo de este período. Se constató una mayor tasa de mortalidad y una mortalidad prematura en las mujeres de 65 años y más. Hubo un mayor porcentaje de fallecidos por aterotrombosis periférica dentro de una institución hospitalaria. Conclusiones: el municipio Cerro mostró una tendencia a la disminución de la mortalidad por enfermedades aterotrombóticas, y un aumento en los años de vida potenciales perdidos por esta causa, donde las mujeres de la tercera edad fueron las más afectadas(AU)


Introduction: mortality data are the pillars of a wide range of indicators of varying complexity; they do not only represent tools for evaluation of the risk of dying in a population and the impact of diseases on health but also the severity of diseases and the survival rate of that population. Objective: to estimate mortality and the years of potential life lost from atherothrombotic diseases in Cerro municipality. Methods: retrospective, descriptive and observational study was conducted on deaths occurred in Cerro municipality due to atherothrombotic diseases in the period of 2000 through 2006 and were analyzed by age, sex, location and causes. For the statistical analysis, the gross and typed mortality rates and the years of potential life lost rates were also estimated. Results: downward trend in mortality and upward trend in the years of potential life lost were observed in this period. The mortality rate and the premature mortality were higher in women aged 65 and over. The percentage of deaths from peripheral atherothrombotic disease in a hospital center was higher. Conclusions: Cerro municipality showed a downward trend in mortality from atherothrombotic disease but an upward trend in the years of potential life lost due to this cause, being the older women the most affected(AU)

ABSTRACT

De forma compactada se explica la relación biológicamente plausible que existe entre la aparición de accidentes cerebrovasculares, particularmente de infarto cerebral isquémico aterotrombótico y la precedencia de enfermedad periodontal inmuno-inflamatoria crónica. Se sugiere la necesidad de estudios que vinculen ambas entidades para conciliar los resultados de las investigaciones internacionales con las realizadas en nuestro medio. Se propone el análisis del estado periodontal en los pacientes pertenecientes a grupos de riesgo o víctimas de enfermedades cerebrovasculares. La consideración de la enfermedad periodontal inmuno-inflamatoria crónica como un factor de riesgo más para el infarto cerebral isquémico aterotrombótico, debe pasar de una interrogante a una estrategia(AU)


The biologically plausible relation existing between the occurrence of cerebrovascular accidents, particularly of atherothrombotic ischemic stroke, and the presence of chronic immunoinflammatory periodontal disease is explained in a compacted way. The need for studies linking both entities is suggested for conciliating the results of the international researches with those carried out in our environment. The analysis of the periodontal state in patients from risk groups of victims on cerebrovascular disease is proposed. Considering the chronic immunoinflammatory periodontal disease as a risk factor for atherothrombotic ischemic stroke should pass from a question to a strategy(AU)

ABSTRACT

BACKGROUND:According to the literature, generalized seizure as a presenting sign of stroke is rare, and in the reported cases it was accompanied by a focal neurological deficit. Presentation of a small ischemic atherothrombotic brain infarction with convulsive generalized seizure is very rare. METHODS:We reported a patient with acute small ischemic atherothrombotic infarction associated with an episode of generalized tonic-clonic seizure, a rare clinical manifestation in this type of stroke. The patient was treated with anti-epileptic therapy after admission. RESULTS:The patient was discharged with oral administration of phenytoin 100 mg TDS, aspirin 80 mg daily, and atorvastatin 40 mg daily. CONCLUSION:Small ischemic atherothrombotic infarction can present only with a seizure without any focal neurological deficit.

ABSTRACT

BACKGROUND AND PURPOSE: Atherothrombotic cerebral infarction [atherothrombotic stroke (ATS)] shares common risk factors and pathophysiological mechanisms with coronary artery disease (CAD), and both diseases appear to have common susceptibility loci. The muscle RAS oncogene homolog gene (MRAS) has been identified as a susceptibility locus for CAD and is implicated in atherosclerosis. The aim of this study was to elucidate whether the single-nucleotide polymorphisms (SNPs) and haplotypes of MRAS are associated with increased risk of ATS in a population of Han Chinese. METHODS: A case-controlled association study was conducted in which only patients with ATS (identified as a major subtype in the Korean modification of the Trial of Org 10172 in Acute Stroke Treatment classification) were enrolled. Subgroup analyses were carried out to determine whether the effect of the MRAS polymorphism was specific to age and gender among the subjects. RESULTS: In total, 194 ATS and 186 control subjects were included in the present study. Two tagging SNPs were identified in MRAS (rs40593 and rs3755751). A multivariate regression analysis revealed a positive association between rs40593 and ATS under dominant and additive models after adjustment for covariates. Subgroup analyses revealed that there were no gender differences with respect to allele or genotype frequencies between the groups. The AG genotype for rs40593 (p=0.028), the CT genotype for rs3755751 (p=0.036), and G-allele carriers (AG plus GG) for rs40593 (p=0.015) exhibited a significant protective effect among those aged > or =45 years. For the haplotype analysis, ATS subjects aged > or =45 years had a higher frequency of the ACAC haplotype (76.0%) than the controls (68.1%; p<0.05); that haplotype was associated with an increased risk of ATS. CONCLUSIONS: The obtained data suggest a positive association between MRAS and ATS among the Han Chinese. Further studies should be performed with larger sample and among different ethnic populations, and gene-gene or gene-environment interactions should be considered.

ABSTRACT

Introducción: la causa más frecuente de enfermedad cerebrovascular isquémica en Cuba es el infarto cerebral de etiología aterotrombótica, que a su vez es más frecuente en el territorio anterior del encéfalo. Objetivo: caracterizar el infarto cerebral aterotrombótico reciente del territorio carotídeo, según la tomografía computarizada. Métodos: estudio descriptivo y transversal en 42 pacientes con diagnóstico clínico de infarto cerebral aterotrombótico de territorio carotídeo, a los que se les realizó tomografía de cráneo. Resultados: la presencia de infarto cerebral de origen aterotrombótico del territorio carotídeo se incrementó con la edad del paciente, alcanzó su pico máximo en los hipertensos mayores de 70 años, con mayor frecuencia en el sexo masculino. El territorio vascular más afectado fue el de la arteria cerebral media en 38 (90,5 %) enfermos, en 23 (54,7 %) pacientes hubo infartos medianos y se observó con mayor frecuencia, 24 (57,2 %) sujetos, la ausencia de infarto antiguo en el territorio anterior del cerebro. Conclusiones: el infarto cerebral aterotrombótico reciente, del territorio carotídeo, se caracteriza por la presencia de infartos medianos que afectan con mayoría casi exclusiva el territorio de la arteria cerebral media con ausencia de la enfermedad cerebrovascular antigua asociada.


Introduction: the most common cause of ischemic stroke in Cuba is atherothrombotic stroke, which, in turn, is more common in the former region of the brain. Objective: to characterize the recent atherothrombotic stroke in the carotid region, according to CT scan. Methods: a descriptive study in 42 patients with clinical diagnosis of atherothrombotic stroke in the carotid region, who underwent cranial CT. Results: the presence of atherothrombotic stroke in the carotid region increased with age. It peaked in hypertensive patients older than 70, and it is much frequently in males. The middle cerebral artery was the most affected in the vascular region in 38 (90.5 %) patients, 23 (54.7 %) patients had middle heart attacks, the absence of previous infarction in the brain anterior region was much frequently observed in 24 (57.2 %) subjects. Conclusions: the recent atherothrombotic stroke in the carotid region is characterized by the presence of middle heart attacks affecting almost exclusively the majority the middle cerebral artery region with absence of previous cerebrovascular disease associated.

ABSTRACT

El síndrome coronario agudo es un problema de salud y constituye la primera causa de muerte en el mundo desarrollado y en Cuba. Esta enfermedad, que incluye infarto de miocardio, angina de pecho y muerte súbita, causa más muertes cada año que el resto de las enfermedades combinadas. El factor causal de mayor relevancia del infarto del miocardio, radica en la formación y evolución crónica de un ateroma, o eventos que son favorecidos por el estrés oxidativo, las citocinas proinflamatorias, la trombina y el no control de los factores de riesgo. La presente revisión se realizó con el propósito de explicar los mecanismos moleculares y la influencia de los factores de riesgo implicados en la fisiopatología de estas enfermedades. Se concluyó que las especies reactivas del oxígeno y el estrés oxidativo, desempeñan un papel importante en la fisiopatología de estas afecciones cardiovasculares, de relevancia para el diagnóstico y la terapéutica


Acute coronary syndrome is a health problem and is the leading cause of death in Europe, North America, and Cuba. This disease, which includes heart attack, angina and sudden death, causes more deaths each year than all other diseases combined. The most important causal factor of myocardial infarction lies in the formation and chronic evolution of atheroma, or events that are favored by oxidative stress, proinflammatory cytokines, thrombin and no control of risk factors. This review was conducted in order to explain the molecular mechanisms and the influence of the risk factors involved in the pathophysiology of these diseases. It was concluded that reactive oxygen species and oxidative stress play an important role in the pathophysiology of such cardiovascular disorders, of relevance for its diagnosis and therapy

ABSTRACT

La enfermedad arterial coronaria (EAC) es la primera causa de muerte en todo el mundo y representa un problema de salud pública en México. El infarto agudo del miocardio (IAM) representa la principal complicación trombótica de la EAC. Aproximadamente 9 % de los nuevos casos está constituido por sujetos menores de 45 años. El IAM se produce por el desarrollo de un trombo en el sitio de la placa aterosclerosa, generando oclusión arterial súbita con isquemia y muerte celular. El IAM resulta de la interacción entre factores genéticos y ambientales. Existen diversos factores de riesgo modificables como la hipertensión arterial, la diabetes mellitus, el tabaquismo, la obesidad y la hipercolesterolemia asociados con el IAM. Sin embargo, numerosos pacientes con IAM no presentan factores de riesgo modificables. En la última década se han identificado variantes genéticas en las proteínas relacionadas con los sistemas de coagulación y fibrinólisis, receptores plaquetarios, disfunción endotelial, flujo sanguíneo anormal, metabolismo de la homocisteína, estrés oxidativo, los cuales se asocian a desarrollo del IAM. La identificación de los polimorfismos asociados a la enfermedad arterial coronaria permitirá desarrollar mejores estrategias de tratamiento e identificación de individuos con alto riesgo para EAC y medidas preventivas en etapas tempranas.


BACKGROUND: Coronary artery disease (CAD) is the first cause of death worldwide and represents a public health issue in our country. Acute myocardial infarction (AMI) represents the main thrombotic complication of CAD. Approximately 9% of the new events of MI occur in patients <45 years of age. DISCUSSION: AMI is produced by development of a thrombus at the site of an atherosclerotic plaque that initiates abrupt arterial occlusion, with ischemia and cell death. AMI results from the interaction of gene-environment factors. There are several modifiable factors such as hypertension, diabetes, smoking, obesity, and hypercholesterolemia associated with AMI. However, in a large number of patients with AMI, modifiable risk factors are not present. In the last decade, several genetic variants (polymorphisms) have been identified associated with AMI in genes related to coagulation proteins, fibrinolytic system, platelet receptors, homocysteine metabolism, endothelial dysfunction, abnormal blood flow and oxidative stress. CONCLUSIONS: Identifying the genes associated with CAD will allow us to develop more efficacious treatment strategies and will also help to identify at-risk subjects, thereby enabling the introduction of early preventive measures. Thus, many research efforts continue to address the identification of acquired and inherited risk factors of this complex disease.

ABSTRACT

Objective:To explore the relationship betwwen the different types of ischemic cerebrovascular disease andthe levels of plasma Homocystine(Hcy).Methods:The levels of plasma Hcy in 135 patients with ischemic cerebrovascular disease were measured by the fluorometric method.All the patients were divided into transient ischemic attack(TLA)group and atherothrombotic cerebral infarction(ACO group.The patients in both groups and the levels of plasma Hcy between the primary ACI and recurrent ACI were compared.Results:The levels of plasma Hcy in the ACI group(22.0±6.4 μmol/L)group were significantly higher than those in the TIA group(16.6±6.0 μmol/L)(P<0.01),and the levels of plasma Hcy in the recurrent ACI group(23.0±5.5 5 μmol/L)were significantly higher than those in the primary group(19.6±5.9 μmol/L)(P<0.01).There were rio significant differences between the two groups in age,sex,history of smoking.lipid,body mass index,as well as the prevalences of hypertension,diabetes mellitus and coronary heart disease.Conclusions:The increased level of plasma Hcy is closely associated with ACI.and it is a risk factor for recurrent stroke.

ABSTRACT

Objective To explore the association between gene polymorphism of interleukin(IL)-4 C590T and serum level of IL-4 and atherothrombotic cerebral infarction(ATCI).Methods The gene polymorphisms of IL-4 C590T in 159 patients with ATCI and 151 normal control subjects were carried out by polymerase chain reaction(PCR)-restriction fragment length polymorphism(RFLP).The serum level of IL-4 in normal control group was determined with enzyme linked immunosorbent assay(ELISA) method.Results In the normal control group,the serum level of IL-4 in TT genotype[(31.85?5.68) pg/ml] was higher significantly than those in TC[(28.67?6.00) pg/ml] and CC genotypes[(20.98?0.99) pg/ml],TC genotype was higher significantly than CC genotype(all P0.05).Conclusions IL-4 590T allele is associated with higher level of serum IL-4.The C590T polymorphism is not associated with the incidence of ATCI.
