ABSTRACT

La exposición a ruido tiene un potencial importante para causar daños a la salud de los trabajadores con efectos auditivos y extra auditivos. El objetivo de la presente investigación fue determinar los niveles de ruido a los que se encuentran expuestos los trabajadores del transporte público de la ciudad de Chihuahua, México, durante la jornada laboral y su asociación con los posibles efectos en la presión arterial. Para ello, se realizaron mediciones de ruido en el ambiente laboral con un dosímetro. Para la medición de presión arterial se utilizó el monitor ambulatorio, el cual mide la presión arterial durante el desarrollo de las actividades laborales. Los parámetros bioquímicos que se midieron fueron colesterol y triglicéridos en ayunas. Con base en los resultados y al análisis de datos se encontró elevada la presión arterial (hipertensión), ruido inestable con variaciones de hasta 106.7 decibeles A (dB A) y un aumento en los lípidos en sangre (triglicéridos). Los resultados nos permiten proponer que la constante exposición al ruido de los choferes de transporte público, es un factor de riesgo importante para el desarrollo de alta presión arterial y un incremento en los niveles de triglicéridos, lo que aumenta el riesgo de sufrir enfermedades cardiovasculares(AU)


Occupational noise exposure can lead to both hearing and non-hearing effects on workers' health. The objective of this study was to measure ambient noise levels that public transportation workers in Chihuahua, Mexico are exposed to, and their association with blood pressure, using a standard noise level dosimeter. We used ambulatory monitors to measure blood pressure over the work shift, and also measured serum cholesterol and triglycerides. Noise levels varied widely, with peaks up to 106.7 decibels (A-scale); we also found elevated blood pressure and triglycerides. Our results suggest that, among public transportation drivers, continuous exposure to noise is a risk factor for elevated blood pressure and triglycerides which, in turn, are risk factors for cardiovascular disease(AU)

ABSTRACT

As neoplasias cardíacas são divididas em primárias e secundárias. As secundárias são 20 a 40 vezes mais comuns do que as primárias. Embora raras, as neoplasias cardíacas primárias podem ser benignas e malignas, sendo as benignas responsáveis por 75% dos casos. Os principais objetivos da imagem cardiovascular são definir a morfologia e etiologia do tumor, identificar potenciais complicações e auxiliar na definição de tratamento. Para o diagnóstico de neoplasias cardíacas, a tomografia por emissão de pósitrons acoplada à tomografia computadorizada (PET-TC) com a fluordesoxiglicose-F18 (18F-FDG) é uma técnica ainda pouco utilizada, principalmente nos tumores cardíacos primários. Entretanto, ela pode ajudar na diferenciação entre tumores malignos e benignos e, assim, evitar biópsias cardíacas e tratamentos invasivos desnecessários. Para esta revisão, realizamos pesquisa na base de dados PubMed, considerando as publicações sobre o tema nos últimos 10 anos. A PET-TC 18F-FDG é um exame útil para diferenciar massas cardíacas benignas das malignas, de acordo com o maior grau de metabolismo glicolítico encontrado nas neoplasias malignas. Além do mais, nos tumores malignos, a PET-TC 18F-FDG tem papel central no estadiamento da doença e pode ajudar na avaliação de resposta ao tratamento

ABSTRACT

Maximal oxygen uptake (VO2max) and both first (VT1) and second (VT2) thresholds have been used as reference points for exercise prescription in different populations. Objective: We aimed to test the hypothesis that exercise prescription, based on VTs determined by treadmill cardiopulmonary exercise testing (CPET), is influenced by the rate of increase in treadmill workload. Methods: Nine healthy individuals underwent two CPETs, followed by two sessions of submaximal exercise, both in randomized order. For the "speed" protocol, there was an increment of 0.1 to 0.3 km.h-1 every 15s. The "grade" incremental protocol increased 1% every 30s and 0.1 km.h-1 every 45s. This was followed by submaximal exercise sessions lasting 40min at an intensity corresponding to heart rate (HR) between the VT1 and VT2. Results: The "speed" protocol resulted in higher VT1 (p = 0.01) and VT2 (p = 0.02) when compared to the "grade" incremental protocol, but there was no effect on VO2max. The target HR for the submaximal exercise sessions was higher in the "speed" protocol compared to the "grade" incremental protocol (p < 0.01) and remained stable during the two steady-state exercise sessions. Blood lactate remained stable during the submaximal exercise sessions, with higher values observed during the "speed" protocol than those "grade" incremental protocol (p < 0.01). Conclusions: Compared to a grade-based protocol, a speed-based protocol resulted in higher VT1 and VT2, which significantly affected cardiorespiratory and metabolic responses to prescribed exercise intensity in healthy young adults

ABSTRACT

The use of technology has increased tremendously, by means of more reliable, smaller, more accessible and specially more user-friendly devices, which provide a wider range of features, and promote significant benefits for the population and health professionals. It is in this context that monitors and apps for heart rate (HR) measurement have emerged. HR is a clinical vital sign of diagnostic and prognostic importance. In response to body movement, HR tends to increase, in a direct relationship with the intensity of exercise. HR was primarily measured by the count of arterial pulse, and recently, HR can be precisely measured by monitors, bracelets and smartphone apps capable to perform real-time measurements and storage of data. This paper aimed to make a brief and updated review on the theme, providing a broader view of advantages and limitations of these resources for HR measurement in exercise. HR monitors and apps use basically two types of technology, optical sensor (photoplethysmography) and electrical signal from the heart. In general, these devices have shown good accuracy in measuring HR and HR variability at rest, but there are differences between brands and models considering the type, mode and intensity of exercise. HR measurements by monitors and smartphone apps are simple, accessible and may help cardiologists in the monitoring of the intensity of aerobic exercise, focusing on health promotion and on primary and secondary prevention of cardiovascular diseases

ABSTRACT

Resumen Introducción: Previamente se desarrolló una nueva metodología de ayuda diagnóstica para los registros Holter fundamentada en los sistemas dinámicos y la teoría de probabilidad, a partir de la información registrada en 21 horas. Objetivo: Evaluar la capacidad diagnóstica de esta metodología durante 19 horas, comparándola con los resultados convencionales del Holter y con los resultados del método matemático aplicado en 21 horas. Materiales y Métodos: fueron evaluados 80 casos de pacientes mayores a 20 años, 10 con registro Holter normal y 70 diagnosticados de forma convencional con diferentes patologías cardíacas. Se establecieron los rangos para las frecuencias cardíacas y de número de latidos por hora en 21 y 19 horas; luego, se calculó la probabilidad de ocurrencia de estos, lo que permitió diferenciar estados de normalidad y enfermedad aguda a partir de tres parámetros. Se comparó el diagnóstico físico-matemático con el diagnóstico convencional, tomado como Gold Standard. Resultados: De los casos normales, dos presentaron probabilidad menor o igual a 0,217 y ocho probabilidades mayores o igual a 0,304; ningún caso de enfermedad aguda presentó valores con probabilidad menor o igual a 0,217, mientras que todos presentaron valores mayores o iguales a 0,304, tanto para los registros Holter evaluados en 21 como en 19 horas. Conclusiones: Se confirmó la utilidad clínica de la metodología ante una reducción del tiempo de evaluación a 19 horas, obteniendo diagnósticos objetivos con base en la auto-organización matemática del fenómeno.


Abstract Background: a new method to help evaluate 21-hour holter recordings based on dynamic systems and the theory of probability was previously developed Aim: to evaluate the diagnostic value of this methodology in the analysis of 19 hr compared to conventional holter analysis over a 21-hr recording. Methods: the holter recordings of 80 subjects aged over 20 years old were analyzed. Ten subjects had a normal holter and 70 conventionally diagnosed as abnormal. Ranges for heart rate and number of beats in 21 or 19 hours were determined. The probability of their occurrence was calculated using 3 parameters. The mathematically derived diagnosis was compared to the clinical diagnosis, considered a gold standard. Results: Among normal cases the calculated probability was ≤ 0.217 in 2 cases and ≥0.304 in 8. No case with acute disease presented probability values ≤0.217; all had probability values ≥0.304, both in 21 and 19 hour recordings. Conclusion: the mathematical methodology described was clinically useful allowing a reduction in recording time from 21 to 19 hr. Clinical diagnosis may be inferred from the mathematical organization of a holter recording.

ABSTRACT

A análise da função diastólica utilizando a ecocardiografia convencional (método bidimensional, Doppler espectral e Doppler tecidual) pode não determinar alguns casos de disfunção diastólica ou elevação da pressão do átrio esquerdo. Os parâmetros que estudam a deformação miocárdica (strain rate e strain longitudinal do átrio esquerdo) podem auxiliar no diagnóstico. Descrevem-se aqui os métodos do strain rate diastólico durante o tempo de relaxamento isovolumétrico e no pico do enchimento, a taxa de torção apical e o strain longitudinal máximo do átrio esquerdo, analisando suas aplicações e vantagens

ABSTRACT

Background: Galectin-3 is the designation given to the protein that binds to ß-galactosides, expressed by activated macrophages and described as a cardiac fibrosis mediator. In hypertrophic cardiomyopathy (HCM), myocardial fibrosis is an independent predictor of adverse outcome; however, the association between Galectin-3 and myocardial fibrosis has not been studied in this cardiopathy. Objective: To evaluate the association of Galectin-3 and the presence of myocardial fibrosis in a patient with hypertrophic cardiomyopathy. Methods: Galectin-3 was measured in automated equipment using the Elisa technique in 100 participants divided into two groups: 50 patients with hypertrophic cardiomyopathy and 50 healthy control subjects. All patients with hypertrophic cardiomyopathy underwent magnetic nuclear resonance with the late enhancement technique to investigate myocardial fibrosis. For the statistical analysis, p values < 0.05 were considered statistically significant. Results: Galectin-3 levels were low and did not show significant differences between patients with hypertrophic cardiomyopathy and the control group,10.3 ± 3.1 ng/dL and 11.3 ± 2.6 ng/dL (p = 0.12) respectively. Myocardial fibrosis was a common finding and was identified in 84% (42/50) of patients with HCM, but no differences were observed between Galectin-3 levels when comparing patients with and without fibrosis, 10.3 ± 2.4 ng/dL and 10.1 ± 2.1 ng/dL (p = 0.59). Conclusion: The results did not show an association between Galectin-3 and myocardial fibrosis in patients with hypertrophic cardiomyopathy, suggesting that non-inflammatory mechanisms of myocardial fibrosis formation and cardiac remodeling are involved in this cardiopathy

ABSTRACT

Introducción: La apnea obstructiva del sueño (AOS) está asociada a alta morbi-mortalidad cardiovascular. Sujetos y métodos: Se seleccionaron 3.657 sujetos entre 30 y 74 años (x: 50,1 ±12,1 DS) de la Encuesta Nacional de Salud 2010. Se estimó el riesgo de AOS mediante una regla de predicción clínica (RPC) basada en las variables del Cuestionario STOP-Bang. Según puntaje se clasificaron en Riesgo BAJO (< 3), MEDIO (3-4) y ALTO (≥ 5) de AOS. El nivel de actividad física (NAF) fue clasificado en 3 niveles: Bajo, Moderado y Alto, según los resultados autorreportados con el cuestionario GPAQ. Para estudiar la asociación entre el riesgo de AOS y NAF con el RCV Alto/Muy Alto (≥ 10%, Framingham) construimos un modelo de regresión logística ajustado por sexo, edad, IMC, diabetes tipo 2, hipertensión arterial, colesterol total elevado, colesterol HDL bajo, triglicéridos elevados, nivel educacional, tabaquismo y horas de sueño autorreportadas. Resultados: 3.098 sujetos se clasificaron como riesgo de AOS: BAJO 1.683 (54,3%), MEDIO 1.116 (36%) y ALTO 299 (9,7%). El NAF fue evaluado en 3.570 sujetos, y clasificado como: Nivel Bajo 1.093 (30,6%), Moderado 705 (19,7%), y Alto 1.772 (49,6%). El RCV fue determinado en 3.613 sujetos, y 711 (19,7%) clasificaron como riesgo Alto /Muy Alto. El modelo de regresión muestra: riesgo MEDIO un OR = 1,75 (1,05-2,90; p = 0,03), riesgo ALTO un OR = 3,86 (1,85-8,06; p < 0,001). Para el NAF Bajo un OR = 1,14 (0,75-1,74; p = 0,525), NAF Moderado un OR = 1,18 (0,73-1,92; p = 0,501). Conclusión: El riesgo MEDIO y ALTO de AOS, pero no el NAF autorreportado, constituyen un factor de riesgo independiente para riesgo cardiovascular elevado.


Introduction: Obstructive sleep apnea (OSA) is associated with high cardiovascular morbidity and mortality. Subjects and methods: 3,657 subjects between 30 and 74 years-old ( x ¯: 50.1 ± 12.1 SD) from 2010 Chilean National Health Survey were selected. Risk of OSA was estimated using a clinical prediction rule (CPR) based on the variables of the STOP-Bang Questionnaire. According to their score they were classified as LOW (< 3), MEDIUM (3-4) and HIGH (≥ 5) risk of OSA. Their physical activity level (PAL) was classified into 3 levels: Low, Moderate and High, according to the self-reported results with the GPAQ questionnaire. To study the association between the risk of OSA and PAL with High / Very High CVR (≥ 10%, Framingham) we constructed a logistic regression model adjusted for sex, age, BMI, type 2 diabetes, high blood pressure, high total cholesterol, low HDL cholesterol, high triglycerides, educational level, smoking and self-reported sleep hours. Results: 3,098 subjects were classified as OSA risk: LOW 1.683 (54.3%), MEDIUM 1.116 (36%) and HIGH 299 (9.7%). The PAL was evaluated in 3,570 subjects and classified as: Low 1,093 (30.6%), Moderate 705 (19.7%), and High 1,772 (49.6%). The CVR was determined in 3,613 subjects, and 711 (19.7%) classified as High/Very High risk. The regression model shows: MEDIUM risk an OR = 1.75 (1.05 - 2.90, p = 0.03), HIGH risk an OR = 3.86 (1.85-8.06, p < 0.001). For the PAL Low an OR = 1.14 (0.75-1.74, p = 0.525), PAL Moderate an OR = 1.18 (0.73-1.92, p = 0.501). Conclusion: The MEDIUM and HIGH risk of OSA, but not the self-reported PAL, constitute an independent risk factor for high cardiovascular risk.

ABSTRACT

Objective: To determine the effect of scaling and root planning treatment on levels of hs-CRP (C-reactive protein) in patients with risk of cardiovascular disease. Material and Methods: This research is an experimental research with one group pre- and post-test design. This research was performed to the periodontal patients who came to the clinic and have risk of cardiovascular disease. Medical evaluations included measurement of blood pressure and body mass index were performed. Blood samples were obtained from each subject after over night fasting, highsensitivity C-reactive protein was measured as an index of inflammation. Blood samples were analysed two times before treatment (scaling and root planning) and three weeks later. Statistical analysis used Paired t-test. The level of significance was set at 5%. Results: Means-CRP levels before and after treatment in scaling and root planning were 3.16 ± 2.37 and 2.18±1.56 (p=0.007). Conclusion: There are significant differences between hs-CRP levels before and after treatment.

ABSTRACT

Objective: To evaluate the facial morphology of Caucasian obese adults in relation to normal weight peers, and to study the association between three-dimensional soft-tissue facial measurements and cardiometabolic risk factors. Material and Methods: Nineteen Caucasian obese subjects aged 25 to 73 years underwent anthropometric measurements, blood samples and a stereophotogrammetric facial scan. Soft-tissue facial linear distances, angles, and volumes were obtained and compared to those collected on normal weight subjects by computing z-scores. Spearman correlation was used to assess the associations between facial measurements and metabolic parameters. Logistic regression analysis adjusted for sex and age was used to assess the risk of metabolic syndrome associated to the facial measurements. Results: Overall, when compared to normal weight persons, obese adults had a wider face in the horizontal dimension, with a middle face (maxilla) that was larger both in absolute value and relatively to the lower face (mandible), and a larger right side gonial angle (Wilcoxon test, p < 0.01). Only the mean (left and right) gonial angle was positively associated to serum triglycerides level, while the other facial measurements were associated with none of the cardiometabolic parameters. Moreover, none of the facial measurements was associated with the risk of metabolic syndrome. Conclusion: Despite larger facial dimensions and altered mandible/maxilla volume ratio, three-dimensional soft-tissue facial morphometry in Caucasian obese adults is not related to cardiometabolic risk factors. The actual association between morphological facial characteristics and clinical information on the health conditions of patients is still to be investigated.

ABSTRACT

A dissecção aguda da aorta (DAA) é uma emergência cardiovascular que acarreta mortalidade alta, 50% a 68% em 48 horas e até 85% em um mês. Este caso refere-se a um homem com 65 anos, ex-tabagista, que teve precordialgia com queimação irradiada para membros superiores, associada a náuseas. O eletrocardiograma mostrou upradesnivelamento ST em parede inferolateral. Recebeu tratamento para infarto agudo do miocárdio com AAS, clopidogrel, enoxaparina e tenecteplase. O cateterismo cardíaco evidenciou DAA tipo A de Stanford e coronárias sem obstruções. O ecocardiograma transtorácico mostrou insuficiência aórtica moderada e dissecção estendendo-se da raiz da aorta até a porção descendente proximal. O paciente foi submetido à cirurgia de Bentall de Bono e enxerto safeno-coronário direito devido à obstrução durante a cirurgia, com boa evolução pós-operatória. A DAA continua a ser um desafio diagnóstico na sala de emergência. De acordo com International Registry of Acute Aortic Dissection, os achados clínicos nas dissecções tipo A incluem dor torácica súbita e intensa (86%), irradiação dorsal (47%), sopro de insuficiência aórtica (44%), assimetria de pressão arterial (50%) e pulsos (30%), alargamento de mediastino à radiografia de tórax (63%) e supradesnivelamento de ST (4%), majoritariamente por oclusão de óstio da coronária direita. O caso destaca-se pela evolução favorável a despeito do tratamento com potencial catastrófico inicialmente direcionado para doença coronariana aguda aterotrombótica


Acute Aortic Dissection (AAD) is a cardiovascular emergency that entails high mortality - 50-68% in 48 hours and up to 85% in one month. This case involves a 65-year-old male ex-smoker who had onset of precordial pain with a burning sensation, radiating into the upper limbs, in combination with nausea. Electrocardiogram showed inferolateral wall ST elevation. He received treatment for acute myocardial infarction with acetylsalicylic acid, clopidogrel, enoxaparin and tenecteplase. Cardiac catheterization revealed Stanford type A AAD and unobstructed coronary arteries. Transthoracic echocardiogram showed moderate aortic regurgitation and aortic dissection extending from the aortic root to its proximal descending portion. The patient underwent a Bentall-De Bono procedure and right coronary artery bypass grafting using the saphenous vein due to obstruction during surgery, with good postoperative progress. AAD remains a diagnostic challenge in the emergency room. According to the International Registry of Acute Aortic Dissection, clinical findings in type A dissections include: sudden severe chest pain (86%), dorsal irradiation (47%), aortic regurgitation murmur (44%), asymmetric blood pressure (50%) or pulse (30%), mediastinal widening on chest radiograph (63%) and ST-segment elevation (4%), mainly due to right coronary ostium occlusion. The case is distinctive because of favorable progress in spite of the potentially catastrophic treatment initially targeting acute coronary atherothrombotic disease

ABSTRACT

As doenças cardiovasculares são a maior causa de morbimortalidade no mundo. A prevenção primária, por meio do diagnóstico precoce, é necessária para possibilitar o tratamento adequado e controlar a evolução da doença, reduzindo a mortalidade e os gastos em saúde pública. Correlacionar aterosclerose em artéria carótida (avaliada pelo Eco Doppler) e disfunção ventricular esquerda (avaliada pelo ecocardiograma), além de correlacionar tais achados com o risco cardiovascular dos pacientes estudados. Método: Foram analisados 286 prontuários de pacientes que realizaram os exames Eco Doppler carotídeo e ecocardiograma transtorácico. Os dados analisados foram: presença de placa aterosclerótica e grau de estenose, fração de ejeção do ventrículo esquerdo e presença de alterações contráteis difusas ou segmentares do ventrículo esquerdo. Resultados: Dos 238 laudos de Eco Doppler carotídeo, 18 tinham estenose maior que 70% em artéria carótida e 14 destes apresentavam alteração contrátil do ventrículo esquerdo (p = 0,045). Dos pacientes que tinham risco cardiovascular muito alto, 61 apresentavam estenose em artéria carótida (p < 0,001); 51 pacientes com risco cardiovascular muito alto apresentavam alteração contrátil (p < 0,001). Dos 266 laudos de ecocardiograma, 37 registravam fração de ejeção do ventrículo esquerdo reduzida. Desses, 25 tinham risco cardiovascular muito alto (p < 0,001). Conclusão: Houve relação positiva entre estenose de artéria carótida, redução da fração de ejeção do ventrículo esquerdo e alteração contrátil do ventrículo esquerdo (difusa ou segmentar) com risco cardiovascular muito alto. Também foi possível correlacionar a estenose carotídea com alteração contrátil, apesar deste estudo não demonstrar correlação entre estenose carotídea e redução da fração de ejeção do ventrículo esquerdo


Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Primary prevention, through early diagnosis, is necessary to enable proper treatment and control disease progression, reducing mortality and public health expenditures. Objective: Correlate carotid artery atherosclerosis (evaluated by Doppler echocardiography) and left ventricular dysfunction (evaluated by echocardiography) and to correlate the findings with the patients' cardiovascular risk. Method: A total of 286 medical records of patients who underwent carotid Doppler echocardiography and transthoracic echocardiography were analyzed. The data analyzed were: presence of atherosclerotic plaque and degree of stenosis, left ventricular ejection fraction and presence of diffuse or segmental left ventricular contractile disorders. Results: Of the 238 reports of carotid Doppler echocardiography, 18 had stenosis greater than 70% in the carotid artery and 14 of those had left ventricular contractile disorders (p = 0.045). Of the patients with very high cardiovascular risk, 61 had carotid artery stenosis (p < 0.001); 51 patients with very high cardiovascular risk had contractile disorders (p < 0.001). Of the 266 echocardiography reports, 37 had reduced left ventricular ejection fraction. Of these, 25 had very high cardiovascular risk (p < 0.001). Conclusion: There was a positive relationship between carotid artery stenosis, reduced left ventricular ejection fraction and left ventricular (diffuse or segmental) contractile disorder with very high cardiovascular risk. It was also possible to correlate carotid stenosis with contractile disorder, although this study did not demonstrate any correlation between carotid stenosis and reduced left ventricular ejection fraction

ABSTRACT

A infância e a adolescência são períodos que compreendem a transição para a vida adulta, no qual ocorrem mudanças no âmbito físico, psicológico, emocional e social. Nesse período tão crucial para o desenvolvimento, fatores ambientais e doenças aos quais os jovens estão expostos podem refletir na vida adulta, gerando maiores chances de desenvolvimento de doenças crônicas, incluindo a doença cardiovascular (DCV). A principal etiologia das doenças cardiovasculares é a aterosclerose, que tem seu início na infância. Dessa forma, é reconhecido atualmente que a prevenção cardiovascular primordial deve iniciar precocemente, na infância e adolescência, antes da instalação da doença de fato, de modo a diminuir a prevalência e incidência das DCV na idade adulta.


Childhood and adolescence constitute the transition to adult life, where changes occur in the physical, psychological, emotional and social spheres. In such a crucial period of deve-lopment, environmental factors and diseases to which young people are exposed may have repercussions in adulthood, increasing the chances of developing chronic diseases, including cardiovascular disease (CVD). The main etiology of cardiovascular diseases is atheroscle-rosis, which has its onset in childhood. Accordingly, it is currently recognized that primordial prevention of cardiovascular disease should begin early, i.e. in childhood and adolescence, prior to its actual onset, in order to reduce the prevalence and incidence of CVD in adulthood.

ABSTRACT

Introducción : En la actualidad, la Minería de Datos es cada vez más popular en el campo de la salud porque existe una necesidad de eficiencia metodológica y analítica para detectar información desconocida y valiosa en datos de salud. Objetivo : Desarrollar un modelo predictivo utilizando técnicas de minería de datos, específicamente Arboles de Decisión, para pesquisar pacientes con propensión a desarrollar Diabetes Tipo II (DM II), Hipertensión Arterial (HTA) o Dislipidemia (DLP). Método : Se analizó el problema de los Factores de Riesgo Cardiovascular Mayores desde una perspectiva de procesos y se estudiaron las técnicas que permiten descubrir el conocimiento del fenómeno almacenado en las bases de datos de Examen de Medicina Preventiva del Adulto (EMPA) de la Población en Control Cardiovascular que presenta DM II, HTA o DLP Resultados : El Algoritmo C5, presenta un mayor poder predictivo, respecto de otros algoritmos de Árbol de Decisión. Se comprobó que las variables Edad y Circunferencia de Cintura fueron las de mayor poder de discriminación en el padecimiento de DM2, HTA o DLP. El algoritmo C5 alcanzó una precisión global de un 83,01% en la partición de prueba, luego en la misma partición el modelo logra discriminar un paciente con algunas de las patologías en el 85,25% de los casos, y uno que no presenta alguna de las patologías en un 80,27% de las oportunidades. Conclusión : La Minería de Datos y en este caso, específicamente los Modelos de Árboles de Decisión son una alternativa válida para la pesquisa cardiovascular temprana.


Introduction : Data Mining is increasingly popular in the health field because there is a need for an efficient analytical methodology to detect unknown and valuable information of health data. Objective : To develop a predictive model using data mining techniques, specifically Decision Trees, to investigate patients with a propensity to develop Type II Diabetes, Arterial Hypertension or Dyslipidemia. The data of adult patients presenting Type II diabetes, Hypertension or Dyslipidemia being followed in a preventive cardiovascular control program were analyzed with the aim of unveiling phenomena that could help develop the prediction of these risk factors. Results : With respect to other decision tree algorithms, Algorithm C 5, showed a greater predictive power. The variables age and waist circumference had the greatest power of discrimination for DM2, HTA or DLP. The C 5 algorithm reached a global precision of 83.01% in the test partition. Then, in the same partition the model managed to discriminate a patient with some of the risk factors in 85.25% of cases, and to rule out any of them in 80.27% of cases. Conclusion : Data Mining, specifically decisión tree models, is a valid alternative for early detection of cardiovascular of risk factors.
