Lesión carotídea extracraneal asintomática y su asociación con cardiopatía isquémica silente
Hernández Pino,Yadira; González Escudero,Hilda; Pacheco Granja,Griselda; Rivero Varona,Martha M.;
Revista Cubana de Medicina , 2006,
Abstract: 71 patients of both sexes aged 60-75 who were diagnosed extracranial carotid damage, but were asymptomatic from the neurological and cardiovascualr point of view, were studied. all of them underwent high resolution color carotid echodoppler and were divided into categories, according to the vascular damage: 30 with intima media thickness >1,1 mm and 41 con stenosis, in addition to a control group of 30 subjects with vascular risk factor without carotid injury. ekg and an ergometric test were performed in all the individuals to define the diagnosis of silent ischemic heart disease. this diagnostic tool was modified for the elderly. recommendations of conditioning and preventive measures were included for any complication.the variables were codified in a computerized database, and contingency (doble entry) tables were made. chi square test was used for the qualitative variables to evaluate the association between the variables of interest, whereas the t students' test was applied to the quantitative variables.the results were considered significant when the probability of association of the tests was < 0.05. the time of action of the vascular risk factors showed a close relation to the carotid damage, mainly smoking (38.2 years as an average). the behavior of the action of the risk factors on the coronary arteries was evidenced in this same order of frequency by the ergometric test. the coincident relation between the carotid and the coronary damage was proved. there was a higher percentage of positive ergometric tests among the elderly with carotid stenosis (57.7 %).

Abstract: Se estudiaron 71 pacientes de los dos sexos, con edades comprendidas entre los 60 y 75 a os, a quienes se les diagnosticó da o carotídeo extracraneal, pero se mantenían asintomáticos desde el punto de vista neurológico y cardiovascular. A todos se les realizó ecodoppler carotídeo a color de alta resolución y quedaron agrupados en 2 categorías, según da o vascular: 30 pacientes con engrosamiento íntima media > 1,1 mm y 41 con estenosis, además, un grupo control de 30 sujetos con factores de riesgo vascular sin lesión carotídea. A todos se les realizó electrocardiograma y prueba ergométrica para definir diagnóstico de cardiopatía isquémica silente. En relación con este medio diagnóstico, se realizaron modificaciones propias para el anciano, incluyendo recomendaciones de acondicionamiento y medidas preventivas para cualquier complicación. Además, se establecieron contraindicaciones específicas, criterios clínicos y electrocardiográficos de positividad y severidad. Las variables se codificaron en una base de datos computarizada, se realizaron tablas de contingencia (de doble entrada); para las variables cualitativas se empleó el test Chi2 para evaluar asociación entre las variables de interés, y para las cuantitativas, el t Student para comparar los promedios en las variables analizadas. Los resultados se consideraron significativos cuando la probabilidad de asociación de los tests fue < 0,05. De los 101 pacientes que constituyeron la muestra, la distribución por sexo fue de 73 femeninos y 28 masculinos. El tiempo de acción de los factores de riesgo vascular mostró íntima relación con el da o carotídeo, fundamentalmente el hábito de fumar (38,2 a os como promedio), seguido por la hipertensión arterial (13,8 a os) y por la diabetes mellitus (10,5 a os). En ese mismo orden de frecuencia, se evidenció el comportamiento de la acción de los factores de riesgo sobre las arterias coronarias por medio de la prueba ergométrica. Se demostró la relación coincidente entre el da o carotídeo y coronario; los ancianos con estenosis carotídea fueron los de mayor porcentaje de pruebas ergométricas positivas (57,7 %), le siguió el engrosamiento íntima media (38,5 %), y para el grupo control solo un 3,8 %. 71 patients of both sexes aged 60-75 who were diagnosed extracranial carotid damage, but were asymptomatic from the neurological and cardiovascualr point of view, were studied. All of them underwent high resolution color carotid echodoppler and were divided into categories, according to the vascular damage: 30 with intima media thickness >1,1 mm and 41 con stenosis, in addit

Revista Cubana de Cardiología y Cirugía Cardiovascular , 2012,
Abstract: Introduction The Movicorde system was designed in order to help cardiologists and physiotherapists atexercise training sessions,where constant supervision of relevant parameters is required.Objectives To evaluate the use of Movicorde in high-risk cardiac patients, including the presence of arrhythmias, ST segmentabnormalities and target heart rate.Methods A descriptive, cross-sectional study of 80 high-risk patients who attended the gymnasium of the Institute of Cardiology,from July 2009 through April 2011, in a Cardiac Rehabilitation (CR) program.The measurements taken by Movicordewere compared to those taken by the cardiologists and a data base was created for statistical analyses.Results Sixty two (62) patients had premature ventricular complexes (PVC). The high specificity (99.87 %), sensibility (80,33%)and the 83,42% positive predictive value (VPP) of the system to detect PVC, was described. There was total concordancebetween the equipment and the physicians in 57 patients (71,25%) with respect to ST segment depression.This had a very superior observed value to that expected and showed that the results were representative (p<0,005).Patients who had acute or recent Myocardial Infarction or chronic ischemic heart disease had intermediate total exercise-session duration and their target heart rate had a similar value which was lesser with respect to the rest of thepatients.Conclusions The Movicorde system showed high efficiency for the telemetric analyses of exercise training sessions and its use isrecommended in clinical practice.

Abstract: Se hizo un estudio longitudinal prospectivo de 64 pacientes infartados, mediante una prueba ergométrica valorativa, ecocardiograma y Holter antes del alta, para evaluar el papel pronóstico de algunos factores medidos por métodos no invasivos en la evolución de los pacientes con infarto agudo del miocardio. Se halló que 70 % de los pacientes fallecidos presentaron alguna alteración en el segmento ST durante la prueba ergométrica, el 100 % presentó síntomas a bajas cargas, incremento de la TA menor de 10 mmHg y variación ST/FC de alto riesgo; la mitad de ellos sufrió arritmias ventriculares; el 100 % de los fallecidos tenían VI remodelado y 70 %, un patrón de llenado restrictivo. La media de la FEVI de los fallecidos fue menor que en los no fallecidos. El índice de la motilidad parietal (IMP) promedio también se correlacionó con la mortalidad. La VFC de los fallecidos fue de 52,2±8,05 y los no fallecidos de 122,74±33,2. La variabilidad de la frecuencia cardíaca (SDANN) menor de 55 ms predijo una mayor mortalidad. A longitudinal and prospective study of 64 infarction patients was conducted by a valorative ergometric test, echocardiogram and Holter before discharge, to evaluate the prognostic role of some factors measured by non-invasive methods in the evolution of the patients with acute myocardial infarction. It was found that 70 % of the dead patients had some alteration in the ST segment during the ergometric test, 100 % presented symptoms at low loads, increase of the arterial pressure under 10 mmHg and high risk variation of ST / HR. Half of them suffered from ventricular arrhitmias. 100 % of the dead had had remodelled VI, whereas 70 % had a restrictive filling pattern. The mean LVEF of the dead was lower than that of the living. The average parietal motility index (PMI) was also correlated to mortality . The heart rate variability (HRV) of the dead was 52.2 ± 8.05 and that of the living patients was 122.74 ± 33.2. The variability of the heart rate ( SDANN ) under 55 ms predicted a higher mortality.

Abstract: La fibromialgia es uno de los síndromes reumáticos más comunes, caracterizado por dolores musculoesqueléticos y puntos dolorosos sin existir sinovitis ni miositis. Se estudiaron 20 pacientes con diagnóstico de fibromialgia para conocer, mediante la prueba ergométrica, las alteraciones del sistema nervioso autónomo. Se observó, en el grupo control, un incremento normal de la frecuencia al adoptar el ortostatismo lo cual refleja activación del sistema simpático, mientras que en las pacientes con fibromialgia no existió dicho reflejo. Se comprobó incremento adecuado de la tensión arterial en el 87 % de las pacientes con fibromialgia, infradesnivel del ST mayor de 1 mm en el 20 % de las pacientes, ausencia de arritmia y síntomas de cardiopatía en todas las pacientes y disminución de la capacidad física en 4.Se concluyó que las pacientes con fibromialgia presentan una disfunción del sistema nervioso autónomo. Fibromyalgia is one of the commonest rheumatic symptoms, characterized by musculoskeletal pain and painful points with neither synovitis nor myositis. 20 patients with diagnosis of fibromyalgia were studied to know the alterations of the autonomous nervous system by the ergometric test. In the control group, it was observed a normal increase of frequency on adopting orthostatism, which reflects the activation of the sympathetic system. This reflex did not exist among the patients with fibromyalgia. An adequate rise of the arterial pressure in 87 % of the patients with fibromyalgia, an infraunevenness of the ST over 1 mm in 20 % of the patients, an absence of arrhytmia and symptoms of heart disease in all patients, and a reduction of physical capacity in 4, were proved. It was concluded that patients with fibromyalgia present a dysfunction of the autonomous nervous system.

Abstract: INTRODUCTION: Tobacco and alcohol are currently the most widely consumed legal psychoactive substances in the world. They represent a heavy burden for health and society in almost all populations. Increasing consumption of both substances is a trend observed in women. OBJECTIVE: Describe the profile of women aged >15 years residing in urban areas of Cuba with respect to tobacco and alcohol consumption. METHOD: Basic information on tobacco and alcohol consumption by Cubans aged >15 years in urban areas was obtained from the Second National Survey on Risk Factors and Chronic Diseases (2001), a national descriptive cross-sectional study, the objective of which was to determine the frequency and epidemiological characteristics of the urban population's main chronic disease risk factors. Sampling design was complex stratified multi-stage cluster. Of a sample of 23,743 individuals, 22,851 were surveyed, representative of 6.8 million Cubans. A questionnaire and structured interview were used. Variables were tobacco and alcohol use, as well as sociodemographic factors: sex, age, educational level, skin color, marital status, type of full-time employment and perceived economic situation. Prevalence, with 95% confidence intervals, and male:female prevalence ratios were estimated. RESULTS: Women who smoked were predominantly aged 40-59 years; had completed less than university education; of black skin color; divorced; laborers, service workers or managers, and with a perceived economic situation as very poor. Women who consumed alcohol were predominantly aged 15-59 years, had at least middle school education, of mestizo or black skin color, of marital status other than widowed; there was no typical profile for occupation or perceived economic situation. Women who were both smokers and alcohol consumers were predominantly 20-59 years, of black or mestizo skin color, of marital status other than widowed; with no typical profile for educational level, occupation or perceived economic situation. CONCLUSIONS: The first nationwide socioeconomic profile of Cuban women using tobacco, alcohol or both constitutes a baseline for comparison to results of a new national study now under way, permitting evaluation of trends over time and effectiveness of prevention and control efforts.
