dc.descriptionIntroducción: La gran mayoría de las medidas de normalidad utilizadas para la interpretación de resonancia cardiaca son extrapoladas de las medidas de ecocardiografía. Los limitados registros de medidas de normalidad se encuentran ajustados en poblaciones extranjeras, no hay registros en latinoamericanos. Objetivo: Determinar las dimensiones cardiacas utilizando resonancia magnética en una población de personas sin antecedente médicos con repercusión cardiaca para lograr una muestra de valores que permitan ajustar las medidas de normalidad utilizadas por nuestro servicio. Materiales y métodos: se analizaron 45 sujetos sanos con edad comprendida entre los 21 y 45 años, las adquisiciones se realizaron utilizando un equipo de RM de 1,5 teslas, el análisis de las imágenes se realizó mediante el programa Cardiac Volume Vx. Se evaluaron múltiples parámetros morfofuncionales a través de análisis estadístico por medio del sistema SPSS versión 23. Resultados: Mediciones obtenidas de ventrículo izquierdo principales fueron volumen diastólico en mujeres de 62 ml +/- 7.1 y en hombres de 65 ml +/- 11.2 y fracción de eyección de 60 % +/- 5 en mujeres y de 62 % +/- 9 en hombres. En ventrículo derecho el volumen diastólico final se encontró 81.8 ml +/- 14.6 en mujeres y 100 ml +/- 24.8 en hombres y fracción de eyección de 53 % +/- 17 en mujeres y de 45 % +/- 12 en hombres. Volumen de fin de diástole de 50 +/- 12.7 ml en mujeres y de 49 ml +/- 19 ml en hombres y fracción de eyección de aurícula izquierda de 55 % +/- 0.08 en mujeres y de 50 % +/- 0.07 en hombres. Volumen de fin de diástole de 44.1 ml +/- 18.5 en mujeres y de 49.2 ml +/- 22.9 en hombres y fracción de eyección de aurícula derecha de 50 % +/- 11 en mujeres y de 45 % +/- 8 en hombres. Se obtuvieron otras medidas lineales y volumétricas adicionales de cavidades cardiacas y de grandes vasos supracardiacos. Conclusiones: se describen los valores de referencia de los parámetros morfofuncionales de las cavidades cardiacas y de vasos supracardiacos. El sexo fue tenido en cuenta como covariable relacionada con la modificación de los parámetros evaluados. Se sugieren variaciones en las medidas de cavidades cardiacas para la población estudiada relacionada con aclimatación crónica a la altitud de la ciudad de Bogotá.spa
dc.description.abstractIntroduction: The vast majority of measures normally used for the interpretation of cardiac magnetic resonance are extrapolated measures echocardiography. Limited records of the normal measures are adjusted foreign populations, there are no records in Latin America. To determine the dimensions using cardiac magnetic resonance in a population of people without medical background with heart impact to achieve a sample set of values that allow normal measures used by our service. Methods: 45 healthy subjects aged between 21 and 45 years were analyzed, acquisitions were made using a team of RM 1.5 tesla, the image analysis was performed using the Cardiac Volume Vx program. Multiple morphological and functional parameters were evaluated by statistical analysis using the SPSS version 23 system. Results: Measurements obtained were major left ventricular diastolic volume in women aged 62 +/- 7.1 ml and 65 ml in men and 11.2 +/- ejection fraction of 60% +/- 5 women and 62% +/- 9 in men. Right ventricular end diastolic volume was 81.8 +/- 14.6 ml found in women and 100 +/- 24.8 ml in men and ejection fraction of 53% +/- 17 women and 45% +/- 12 men. End-diastolic volume of 50 +/- 12.7 ml in men and 49 ml +/- 19 ml in men and ejection fraction of left atrium of 55% +/- 0.08 in women and 0.07 in +/- 50% men. End-diastolic volume of 18.5 +/- 44.1 ml in women and 22.9 +/- 49.2 ml in men and ejection fraction of the right atrium of 50% +/- 11 women and 45% +/- 8 men . Additional linear and volumetric measurements of cardiac cavities and large vessels supracardiacos obtained. Conclusions: the reference values of the morphological and functional parameters of the heart chambers and vessels supracardiacos described. Sex was taken into account as a covariate associated with the modification of the parameters evaluated. Suggested changes in measures of cardiac cavities for the population studied related chronic altitude acclimatization Bogota.eng
