Importancia pronóstica de la enfermedad arterial periférica diagnosticada mediante el índice tobillo-brazo en población general española / Prognostic importance of diagnosticated peripheral arterial disease through the ankle brachial index in spanish general population

OBJETIVO: Determinar el valor pronóstico de tener un índice tobillo-brazo (ITB) bajo para padecer distintas enfermedades cardiovasculares y si mejora la capacidad predictiva de las principales funciones de riesgo cardiovascular. DISEÑO: Estudio de cohorte poblacional. EMPLAZAMIENTO: Área sanitaria Don Benito-Villanueva de la Serena (Badajoz). España. PARTICIPANTES: Se seleccionaron 2.833 sujetos representativos de los residentes, entre 25 y 79 años. MEDICIONES: Se midió el ITB en la inclusión y se registró el primer episodio de cardiopatía isquémica o ictus, la mortalidad cardiovascular y total en siete años de seguimiento. Se calcularon los hazard ratio (HR), ajustados por factores de riesgo cardiovascular, para el ITB bajo (< 0,9). Se determinaron los índices de reclasificación neta por categorías, clínica y continua para las funciones REGICOR, FRESCO cardiopatía isquémica, FRESCO enfermedad cardiovascular y SCORE. RESULTADOS: Se analizaron 2.665 sujetos tras excluir las personas con antecedentes cardiovasculares y las pérdidas. El ITB bajo se asoció con un mayor riesgo, alcanzando una HR (IC 95%) de 6,45 (3,00 - 13,86), 2,60 (1,15 - 5,91), 3,43 (1,39 - 8,44), 2,21 (1,27 - 3,86) para ictus, cardiopatía isquémica, mortalidad cardiovascular y total, respectivamente. La inclusión del ITB mejoró el índice de reclasificación (IC 95%) en el riesgo intermedio según FRESCO cardiovascular en un 24,1% (10,1 - 38,2). CONCLUSIONES: El ITB bajo está asociado con un incremento importante del riesgo de ictus, cardiopatía isquémica, mortalidad cardiovascular y total en nuestro medio. La inclusión del ITB mejoró la reclasificación de las personas con riesgo intermedio, según FRESCO cardiovascular, por lo que estaría justificada su utilización en esa categoría de riesgo

OBJECTIVE. The objectives have been to determine the prognostic value of having a low ankle-brachial index (ABI) for different cardiovascular diseases and whether it improves the predictive capacity of the main cardiovascular risk scores proposed for Spain. DESIGN: Population-based cohort study. LOCATION: A health area of the province of Badajoz (Spain). PARTICIPANTS: 2,833 subjects, representative of residents, between 25 and 79 years old, MEASUREMENTS: The ABI was measured at baseline and the first episode of ischemic heart disease or stroke, cardiovascular and total mortality, was recorded during 7 years of follow-up. The hazard ratio (HR) adjusted for cardiovascular risk factors and net reclassification index (NRI) by category, clinical and continuous for the risk functions REGICOR, FRESCO coronary heart disease, FRESCO cardiovascular disease and SCORE, were calculated. RESULTS: 2,665 subjects were analysed after excluding people with cardiovascular history and loss of follow-up. Low ABI was associated with adjusted HR (95% CI): 6.45 (3.00 - 13.86), 2.60 (1.15 - 5.91), 3.43 (1.39 - 8.44), 2.21 (1.27 - 3.86) for stroke, ischemic heart disease, cardiovascular mortality and total mortality respectively. The ABI improved the NRI (95% CI) in the intermediate risk category according to FRESCO cardiovascular equation by 24.1% (10.1 - 38.2). CONCLUSIONS: Low ABI is associated with a significant increase in the risk of stroke, ischemic heart disease, cardiovascular mortality and total mortality in our population. The inclusion of ABI improved the reclassification of people at intermediate risk, according to FRESCO cardiovascular, so its use in that risk category would be justified

Severity of obesity and cardiometabolic risk factors in adults: Sex differences and role of physical activity. The HERMEX study.

BACKGROUND: The aims of this study were 1) to examine potential sex-related differences in major cardiometabolic risk factors among severe/morbid obese (body mass index [BMI]≥35) individuals; 2) to assess whether severity of obesity is associated with more adverse cardiometabolic risk factors in women and men, and 3) to assess whether being physically active (≥500 metabolic equivalents [MET-minutes per week]) may play a role in the association between severity of obesity and the cardiometabolic risk profile. METHODS: A total of 886 (438 men) obese individuals participated in a population-based cross-sectional study. We categorized participants as grade I (BMI 30-34.99) and grade II/III (BMI≥35) obese. We measured markers of lipid and glucose metabolism, inflammation (high sensitivity C-reactive protein [hs-CRP]) blood pressure and renal function, as well as self-reported physical activity. RESULTS: Triglycerides, insulin, HOMA-IR, systolic blood pressure and creatinine levels were higher in severe/morbid obese men than women (all, P<0.05), while women presented higher HDL cholesterol and hs-CRP (P<0.05) than men. Severe/morbid obesity was associated with higher triglycerides, hs-CRP, insulin and insulin resistance, diastolic blood pressure and higher odds of hypertension than grade I obesity both in women and men (all, P<0.05). Severe/morbid obese individuals who were physically inactive presented the least favorable cardiometabolic profile (P<0.05). CONCLUSIONS: Severe/morbid obesity is associated with more adverse cardiometabolic risk factors both in women and men. Severe/morbid obese men are more affected than women regarding their cardiometabolic profile, although women presented higher inflammation. Physically inactive individuals with severe/morbid obesity had the most adverse clustered cardiometabolic risk profile.

Cholesterol and cardiovascular disease in the elderly. Facts and gaps.

Hypercholesterolemia is a major cardiovascular risk factor that increases the incidence of atherosclerotic diseases in adults, although the association is less well established in the elderly. The role of statins is well characterized for the reduction of myocardial infarction incidence or death in individuals with a history or high risk of cardiovascular diseases, regardless of age. Therapeutic measures recommended to prevent cardiovascular diseases and to reduce cholesterol levels in the elderly, such as lifestyle changes and lipid-lowering drugs, particularly statins, are based on studies conducted in younger adults. This narrative review aims to summarize the main observational studies and randomized clinical trials that have studied the relationship between cholesterol and cardiovascular diseases and the potential benefits and drawbacks of statins use in elderly patients.

Prevalence of left-ventricular hypertrophy by multiple electrocardiographic criteria in general population: Hermex study.

OBJECTIVES: To determine the prevalence of left-ventricular hypertrophy (LVH) in the general population by means of multiple electrocardiographic criteria and those variables independently associated. METHODS: Random-sample cross-sectional study of the general population aged between 25 and 79 years, representative of a health area, was conducted. An electrocardiogram was recorded 'on line' in the Electropres project website; 17 LVH criteria together with two combined criteria were used. By multivariate analysis we examined those variables independently associated with the presence of electrocardiographic LVH. RESULTS: We recruited 2564 individuals, mean age 50.9 [standard deviation (SD) 14.7] years, 45.7% men. The criteria more prevalent were: Dalfó 19.4%, RV6/V5 14.5%, Perugia 10.9%, any combination with at least three positive criteria (Combined 3) 9.4%, Romhilt 7.5%, Lewis 6.2% and the recommended criteria of the European Society of Hypertension 4%. The best prevalence ratio between hypertensive and normotensive individuals was achieved with Lewis, Dalfó and Perugia criteria. The least prevalence was Sokolow 0.7%. The variables that were independently associated with the presence of LVH by Combined 3 criterion were pulse pressure at least 50 [odds ratio (OR) 2.13, 95% confidence interval (CI) 1.47-3.09], arterial hypertension (OR 1.75, 95% CI 1.21-2.53) and smoking (OR 0.69, 95% CI 0.50-0.95). CONCLUSIONS: The detection ability of the electrocardiogram with regard to the LVH may improve with the use of other criteria than those currently recommended by the guidelines. The presence of LVH is positively associated with hypertension and elevated pulse pressure and negatively with a history of smoking.

Introduction Childhood obesity is a major and increasing health problem for society because it increases the risk of cardiovascular disease, type 2 diabetes mellitus, and hypertension. Thus, when obese children become obese adults, effects on their health and life expectation may be devastating. Objectives(1) To assess the prevalence of metabolic syndrome (MS) in a child population with obesity and (2) to compare anthropometric and biochemical parameters in patients with one or two parameters of MS syndrome to those of patients who meet MS criteria. Patients and methods A descriptive, cross-sectional study was conducted in children and adolescents with severe obesity (weight >p97) seen at the endocrinology department of Hospital de Getafe. Variables examined included age, sex, height, weight, body mass index (BMI), waist circumference (WC), oral glucose tolerance test (OGTT), insulin, insulin resistance (IR) measured by HOMA, triglycerides (Tg), high density lipoprotein (HDL), and systolic and diastolic blood pressure (SBP and DBP). The definition of MS in adolescents was made according to criteria of the International Diabetes Federation (IDF), 2007.ResultsA total of 133 patients, 67 males (50.4%) and 66 females (49.6%) with a mean age of 12.17±3.27 years, were enrolled into the study. All patients were obese, with a weight greater than the 97h percentile for age and sex. Prevalence of several cardiovascular risk factors was as follows: WC ≥90th percentile for age and sex, 100%; hypertension, 26.08%; hypertriglyceridemia ≥150mg/dL, 15.94%; HDL <40mg/dL, 10.86%; fasting blood glucose levels ≥100mg/dL, 7.97%.

Introducción y objetivos Estimar la prevalencia de la obesidad y el riesgo cardiovascular asociado en la población general de un área de salud de Extremadura. Material y métodos Estudio transversal sobre una muestra aleatoria de población entre 25 y 79 años procedente del área de salud de Don Benito-Villanueva (Badajoz). Se estudió la presencia de factores de riesgo y enfermedad cardiovascular. Se recogieron medidas antropométricas, de presión arterial y muestra sanguínea. Se categorizó a la población obesa en distintos niveles de riesgo tal como propone la Sociedad Española para el Estudio de la Obesidad y se estudió la influencia de la obesidad en la estimación del riesgo de cardiopatía isquémica según la función de Framinghan adaptada para España. Resultados De los 3.521 sujetos seleccionados participaron 2.833 (80,5%). La edad media fue 51,2 años (DE 14,7) y el 46,5% fueron hombres. La prevalencia de sobrepeso y obesidad fue superior en hombres (46,2 y 37,7%) con respecto a las mujeres (37,7 y 32,6%) (p<0,005 y p<0,05 respectivamente). Solo el 10% de los obesos no mostraron un riesgo cardiovascular aumentado. La obesidad se asoció a un incremento de presentar riesgo alto de cardiopatía isquémica de 8 veces en la mujer (p<0,001) por 1,4 veces en el hombre (p=0,095).Conclusiones La obesidad es muy prevalente y afecta junto al sobrepeso al 74,1% de la población de un área de salud de Extremadura. La amplia mayoría de los obesos tienen un riesgo cardiovascular aumentado, siendo de gran magnitud para la cardiopatía isquémica en la mujer (AU)

Introduction and objectives To estimate the prevalence of obesity and its associated cardiovascular risk in the general population of a health area in Extremadura. Materials and methods A cross-sectional study on a random population sample aged 25-79 years from the Don Benito-Villanueva (Badajoz) health area. Risk factors and cardiovascular disease were examined. Anthropometric and blood pressure measurements were collected, and a blood sample was taken. Obese subjects were categorized into different risk levels as proposed by the Spanish Society for the Study of Obesity, and the influence of obesity on estimation of the risk of ischemic heart disease was studied using the Framingham function, as adapted for Spain. Results A total of 2833 of the 3521 subjects screened (80.5%) participated in the study. Mean age was 51.2 years (SD 14.7), and 46.5% were males. Male subjects had a greater prevalence of overweight and obesity (46.2% and 37.7% respectively) as compared to females (37.7% and 32.6%) (p<0.005 and p<0.05, respectively). Only 10% of obese subjects had no increased cardiovascular risk. Obesity was associated to an 8-fold increase in the presence of a high risk for ischemic heart disease in females (p<0.001), as compared to a 1.4-fold increase in males (p=0.095).Conclusions Obesity is highly prevalent and affects, together with overweight, 74.1% of the population in an Extremadura health area. A vast majority of obese subjects have an increased cardiovascular risk, which is very marked for ischemic heart disease in females (AU)

Síndrome metabólico en España: prevalencia y riesgo coronario asociado a la definición armonizada y a la propuesta por la OMS. Estudio DARIOS / Metabolic syndrome in Spain: prevalence and coronary risk associated with harmonized definition and WHO proposal. DARIOS study

Introducción y objetivos. Actualizar la prevalencia del síndrome metabólico en España y su riesgo coronario asociado, empleando la definición armonizada y la nueva propuesta de la Organización Mundial de la Salud (síndrome metabólico premórbido), que excluye diabetes mellitus y enfermedad cardiovascular. Métodos. Análisis agrupado con datos individuales de 11 estudios, incluyendo a 24.670 individuos de 10 comunidades autónomas con edad 35-74 años. El riesgo coronario se estimó con la función REGICOR. Resultados. La prevalencia de síndrome metabólico fue del 31% (mujeres, 29%; intervalo de confianza del 95%, 25-33%; varones, 32%; intervalo de confianza del 95%, 29-35%). Entre los varones con síndrome metabólico, fueron más frecuentes la elevación de glucemia (p=0,019) y triglicéridos (p<0,001); por contra, entre las mujeres predominaron obesidad abdominal (p<0,001) y colesterol unido a las lipoproteínas de alta densidad bajo (p=0,001). Las personas con síndrome metabólico mostraron riesgo coronario moderado (varones, 8%; mujeres, 5%), pero mayor (p<0,001) que la población sin síndrome metabólico (varones, 4%; mujeres, 2%). El incremento de riesgo coronario asociado al síndrome metabólico fue mayor en mujeres que en varones (2,5 frente a 2 veces, respectivamente; p<0,001). La prevalencia de síndrome metabólico premórbido fue del 24% y su riesgo coronario asociado también aumentó más en las mujeres que en los varones (2 frente a 1,5; p<0,001). Conclusiones. La prevalencia de síndrome metabólico es del 31%; el síndrome metabólico premórbido la rebaja al 24% y delimita la población para prevención primaria. El incremento de riesgo coronario es proporcionalmente mayor en las mujeres, tanto en síndrome metabólico como en síndrome metabólico premórbido (AU)

Introduction and objectives. To update the prevalence of metabolic syndrome and associated coronary risk in Spain, using the harmonized definition and the new World Health Organization proposal (metabolic premorbid syndrome), which excludes diabetes mellitus and cardiovascular disease. Methods. Individual data pooled analysis study of 24 670 individuals from 10 autonomous communities aged 35 to 74 years. Coronary risk was estimated using the REGICOR function. Results.Prevalence of metabolic syndrome was 31% (women 29% [95% confidence interval, 25%-33%], men 32% [95% confidence interval, 29%-35%]). High blood glucose (P=.019) and triglycerides (P<.001) were more frequent in men with metabolic syndrome, but abdominal obesity (P<.001) and low high-density lipoprotein cholesterol (P=.001) predominated in women. Individuals with metabolic syndrome showed moderate coronary risk (8% men, 5% women), although values were higher (P<.001) than in the population without the syndrome (4% men, 2% women). Women and men with metabolic syndrome had 2.5 and 2 times higher levels of coronary risk, respectively (P<.001). Prevalence of metabolic premorbid syndrome was 24% and the increase in coronary risk was also proportionately larger in women than in men (2 vs 1.5, respectively; P<.001). Conclusions. Prevalence of metabolic syndrome is 31%; metabolic premorbid syndrome lowers this prevalence to 24% and delimits the population for primary prevention. The increase in coronary risk is proportionally larger in women, in both metabolic syndrome and metabolic premorbid syndrome (AU)

Male subjects had a greater prevalence of overweight and obesity (46.2% and 37.7% respectively) as compared to females (37.7% and 32.6%) (p<0.005 and p<0.05 respectively). Only 10% of obese subjects had no increased cardiovascular risk. Obesity was associated to an 8-fold increase in the presence of a high risk for ischemic heart disease in females (p<0.001), as compared to a 1.4-fold increase in males (p=0.095). CONCLUSIONS: Obesity is highly prevalent and affects, together with overweight, 74.1% of the population in an Extremadura health area. A vast majority of obese subjects have an increased cardiovascular risk, which is very marked for ischemic heart disease in females.

Prevalencia de síndrome metabólico según las nuevas recomendaciones de la OMS. Estudio HERMEX / Prevalence of metabolic syndrome estimated with the new World Health Organization recommendations. The HERMEX study

Objetivos La unificación de criterios para el diagnóstico del síndrome metabólico, junto con la propuesta de la Organización Mundial de la Salud de eliminar de ellos a los pacientes con diabetes o con enfermedades cardiovasculares, cambiará la estimación de su prevalencia. Nuestro objetivo fue determinar la prevalencia del síndrome metabólico en un área de salud extremeña siguiendo ambas recomendaciones. Métodos Estudio transversal, poblacional, con selección aleatoria de individuos entre 25 y 79 años de edad, en un Área de Salud de Badajoz. Se recogieron los antecedentes de factores de riesgo cardiovascular, la presión arterial y el perímetro abdominal, y una muestra de sangre en ayunas. Se comparó la prevalencia del síndrome metabólico siguiendo los recientes criterios, por sexo y edad. Resultados Se reclutaron 2.833 personas, el 46,5% eran hombres, y la edad media 51,2 años. La prevalencia del síndrome metabólico fue del 33,6%, significativamente mayor en los hombres (36,7% frente a 30,9%; p<0,001) y con una disminución significativa al excluir la diabetes y la enfermedad cardiovascular (20,8%; p<0,001). La diferencia de prevalencia con los distintos criterios fue significativa para el total y por sexo (p<0,001), a partir del decenio de edad de 45-54 años en los hombres y de 55-64 años en las mujeres. Conclusiones La prevalencia de síndrome metabólico en el área estudiada es de las más altas halladas en España en estudios poblacionales. Aunque se reduce con las nuevas recomendaciones internacionales, indica una población considerable y joven en la cual aplicar medidas preventivas (AU)

Objectives The unification of criteria for the diagnosis of metabolic syndrome, together with the subsequent World Health Organization (WHO) proposal to eliminate diabetes and cardiovascular diseases from the diagnostic criteria, will change estimates of the known prevalence of this syndrome. The aim of this study was to determine the prevalence of metabolic syndrome in a health area of Badajoz (Spain) using the latest consensus criteria and eliminating diabetes and cardiovascular disease. Methods We performed a cross-sectional population-wide study of randomly selected individuals aged between 25 and 79 years old in a health area of Badajoz. In all patients, data on their history of cardiovascular risk factors were gathered, waist circumference and blood pressure were measured and a fasting blood sample was collected. The prevalence of metabolic syndrome, following recent criteria, was compared by age and gender. Results We recruited 2,833 individuals (46.5% men). The mean age was 51.2 years The prevalence of metabolic syndrome was 33.6% and was significantly higher in men (36.7% vs 30.9%; p<0.001). The prevalence of metabolic syndrome fell significantly after exclusion of patients with diabetes or cardiovascular disease (20.8%; p<0.001). The difference in prevalence between the distinct criteria was significant for the whole population and by sex (p<0.000). A significant difference in prevalence between genders was observed from the age of 45-54 years in men and 55-64 years in women Conclusions The prevalence of metabolic syndrome in a health area of Badajoz is among the highest reported in population-based studies in Spain. Although estimates of the prevalence are decreased by the new international recommendations, a considerable proportion of the young population requires preventive measures (AU)

Level of blood pressure control in a hypertensive population when measurements are performed outside the clinical setting.

BACKGROUND: To determine whether the number of optimally controlled hypertensive patients is higher using self-measurement of blood pressure at home and ambulatory monitoring, compared to using conventional blood pressure measurements at the doctor's office. METHOD: An observational, cross-sectional, multicentre, descriptive study of a random sample of 237 primary health care patients, known to be hypertensive, from Badajoz (Spain). Blood pressure was measured at the doctor's office and by self-measurement at home. Those patients showing good control by self-measurement were subjected to 24-hour ambulatory monitoring. Optimal control was understood as blood pressure < 140/90 mm Hg when measured at the doctor's office, and < 135/85 mm Hg when self-measured at home and by daytime ambulatory monitoring. RESULTS: Mean systolic/diastolic measurements at the doctor's office and by self-measurement were 145.6/83.9 and 134.0/78.7 mm Hg, respectively (p < 0.000). In the population optimally controlled by self-measurement and who subsequently received ambulatory monitoring, the mean blood pressure was 121.8/73.4 and 125.6/76.2 mm Hg, respectively (p = 0.002; p < 0.000). When measured at the doctor's office blood pressure was controlled in about 29.5% (95% CI 23.7-35.3%) of patients, in 38% when self-measured (95% CI 31.4-44.2%; p < 0.000), and in 24.5% when it was confirmed through ambulatory monitoring (95% CI 15.4-33.6%). Sensitivity and positive predictive values of the office measurements for the detection of patients who were well-controlled by self-measurement were 50% and 64.3%, respectively, and 53.4% and 73.8% as regards ambulatory monitoring. CONCLUSIONS: A higher level of control is achieved with self-measurement at home not confirmed by ambulatory monitoring. Therefore, the white coat effect does not seem to influence the percentage of well-controlled patients detected at the doctor's office. Office blood pressure does not appear to be useful in distinguishing which individual patients are optimally controlled.
