The question about what risk function should be used in primary prevention remains unanswered. The Framingham Study proposed a new algorithm based on three key ideas: use of the four risk factors ...with the most weight (cholesterol, blood pressure, diabetes and smoking), prediction of overall cardiovascular diseases and incorporating the concept of vascular age. The objective of this study was to apply this new function in a cohort of the general non Anglo-Saxon population, with a 10-year follow-up to determine its validity.
The cohort was studied in 1992-94 and again in 2004-06. The sample comprised 959 randomly-selected persons, aged 30-74 years, who were representative of the population of Albacete, Spain. At the first examination cycle, needed data for the new function were collected and at the second examination, data on all events were recorded during the follow-up period. Discrimination was studied with ROC curves. Comparisons of prediction models and reality in tertiles (Hosmer-Lemeshow) were performed, and the individual survival functions were calculated.
The mean risks for women and men, respectively, were 11.3% and 19.7% and the areas under the ROC curve were 0.789 (95%CI, 0.716-0.863) and 0.780 (95%CI, 0.713-0.847) (P<0.001, both). Cardiovascular disease events occurred in the top risk tertiles. Of note were the negative predictive values in both sexes, and a good specificity in women (85.6%) and sensitivity in men (79.1%) when their risk for cardiovascular disease was high. This model overestimates the risk in older women and in middle-aged men. The cumulative probability of individual survival by tertiles was significant in both sexes (P<0.001).
The results support the proposal for "reclassification" of Framingham. This study, with a few exceptions, passed the test of discrimination and calibration in a random sample of the general population from southern Europe.

Resumen La prevención de la enfermedad cardiovascular (ECV) constituye una prioridad fundamental en la práctica clínica diaria, tanto en Enfermería como en Medicina. Para conseguirla, el control de ...la dislipidemia es fundamental y la elaboración de guías por expertos, basadas en la evidencia disponible, el modo más racional de su abordaje. Pero en ocasiones, la producción científica llega a ser tan abundante que seleccionar la calidad de los estudios puede generar controversias. Este es el caso que se presenta en este estudio, donde las guías estadounidenses, basadas en ensayos clínicos aleatorizados y controlados, han establecido un nuevo paradigma frente a las guías europeas que además han considerado los diseños de estudios observacionales. Se exponen los puntos fundamentales de ambos casos, la controversia generada y el posterior acercamiento entre ambas guías, valorando la importancia que aporta la evidencia científica.
Introduction: home confinement due to the COVID-19 pandemic can influence the dietary profiles of the population, suddenly subjected to a stressful factor that implies important modifications in life ...habits. Among others, a restriction of mobility and a change in the way of carrying out work, going from being face-to-face to non-contact (teleworking). Objective: to know the usual dietary pattern prior to confinement, and to assess the evolution of adherence to the Mediterranean diet weekly until its conclusion. Methods: data were collected using a weekly anonymous online questionnaire that monitored adherence to the Mediterranean diet in real time in an initial sample of 490 adults from Spain. Adherence to the Mediterranean diet was assessed using the MEDAS (Mediterranean Diet Adherence Screener) and modified PREDIMED questionnaires. Results: confinement due to the COVID-19 pandemic influenced the eating habits of the participants, so that adherence to the Mediterranean diet increased at the end of the confinement period, which is of special interest, since it was based on a good initial adherence (MEDAS adherence: 10.03 ± 1.9 initial and 10.47 ± 2.1 final; p = 0.016; modified PREDIMED adherence: 9.26 ± 2.0 initial and 9.89 ± 2.1 final; p < 0.001), without observing clinically relevant changes in body composition as measured by body mass index (BMI) except in women (23.3 kg/m2 ± 2.9 initial and 23.4 kg/m2 ± 2.9 final; p < 0.001), with a slight increase in this parameter, but maintaining on average the healthy values recommended by the guidelines. Conclusions: in the studied population we observed an improvement in adherence to the Mediterranean diet without observing clinically relevant changes in BMI.
Resumen Objetivo. El envejecimiento implica padecer enfermedades crónicas y ansiedad. Los objetivos han sido relacionar la ansiedad con las enfermedades cardiovasculares (ECV) y sus factores de ...riesgo (FRCV). También con la actividad física (AF) y el consumo de alcohol y tabaco. Método. Estudio observacional y analítico, transversal. Participaron 27 voluntarios (16 mujeres) mayores de 65 años. La ansiedad se valoró con la escala de Hamilton.

La media de ansiedad somática fue 3,1 en los que hacían otro tipo de AF frente a 4,3 en los que no (p=0,025). Conclusiones. No se ha encontrado relación entre la ansiedad y las ECV y sus FRCV. Tampoco con el consumo de tabaco. Sí con el consumo de alcohol y la AF.
the aim of the present study was to assess the level of physical activity and its association with Mediterranean dietary patterns in university students of health sciences at Universidad de ...Castilla-La Mancha (Spain).
a cross-sectional study was performed through an online survey. The final sample consisted of 555 university students (78.2 % females). Adherence to Mediterranean diet was assessed using the 14-item Mediterranean Diet Adherence Screener (MEDAS). To measure physical activity, the Rapid Assessment of Physical Activity Scale (RAPA) questionnaire was used.
according to physical activity, 2.5 % of the participants were considered active and 35.1 % did both strength and flexibility activities. A greater association was seen between intake of fruits (OR = 1.95; 95 % CI, 1.25-3.04), pulses (OR = 1.51; 95 % CI, 1.00-3.20), and nuts (OR = 1.99; 95 % CI, 1.33-2.99) in those considered sufficiently active. Similarly, we found a significant relationship between the intake of fruits (OR = 2.28; 95 % CI, 1.49-3.47), pulses (OR = 1.41; 95 % CI, 1.00-2.08), nuts (OR = 1.96; 95 % CI, 1.34-2.86), and fish/seafood (OR = 1.67; 95 % CI, 1.15-2.43) in those who engaged in both strength and flexibility activities.
this study suggests that consumption of certain Mediterranean foods was associated with higher levels of physical activity in a sample of Spanish university students.
Obesity represents an important health problem and its association with cardiovascular risk factors is well-known. The aim of this work was to assess the correlation between obesity and mortality ...(both, all-cause mortality and the combined variable of all-cause mortality plus the appearance of a non-fatal first cardiovascular event) in a general population sample from the south-east of Spain.
This prospective cohort study used stratified and randomized two-stage sampling. Obesity body mass index (BMI) ≥ 30 kg/m(2) as a predictive variable of mortality and cardiovascular events was assessed after controlling for age, sex, cardiovascular disease history, high blood pressure, diabetes mellitus, hypercholesterolemia, high-density lipoprotein/triglycerides ratio, total cholesterol and smoking with the Cox regression model.
The mean follow-up time of the 1,248 participants was 10.6 years. The incidence of all-cause mortality during this period was 97 deaths for every 10,000 person/years (95% CI: 80-113) and the incidence of all-cause mortality+cardiovascular morbidity was 143 cases for every 10,000 person/years (95% CI: 124-163). A BMI ≥ 35 kg/m(2) yielded a hazard ratio for all-cause mortality of 1.94 (95% CI: 1.11-3.42) in comparison to non-obese subjects (BMI <30 kg/m(2)). For the combination of cardiovascular morbidity plus all-cause mortality, a BMI ≥ 35 kg/m(2) had a hazard ratio of 1.84 (95% CI: 1.15-2.93) compared to non-obese subjects.
A BMI ≥ 35 kg/m(2) is an important predictor of both overall mortality and of the combination of cardiovascular morbidity plus all-cause mortality.

Resumen Introducción. La elección de los alimentos en época de confinamiento están influenciadas por múltiples factores como pueden ser la disponibilidad alimentaria que puede verse reducida y que ...constituyó uno de los principales retos a afrontar por los gobiernos en las pandemias pasadas, el estatus económico familiar que puede variar, así como el propio hecho del confinamiento que proporciona al grupo familiar de más tiempo para dedicar a la preparación de distintos platos pero también les sitúa en una situación que puede ser vivida como estresante y conducir a pautas distintas de consumo alimentario. Objetivo. Conocer el patrón dietético habitual, es decir previo al confinamiento recabando esta información en el momento en que se iniciaba aquel. Método. Estudio observacional transversal mediante encuesta alimentaria telemática anónima en línea que monitorizó la adherencia a la dieta mediterránea en tiempo real en 492 adultos de España en la pandemia por covid19 durante la segunda quincena del mes marzo 2020.

Nuestro estudio muestra que el grado de adherencia a la DM en la primera parte del confinamiento ha sido elevado, mostrando una puntuación de 10.0 ± 2.0 en el test de MEDAS y de 9.3± 2.1 en el PREDIMED modificado. En concreto en nuestro estudio un 77% de la población estudiada presenta una alta adherencia a la dieta mediterránea frente a moderada adherencia el 22,4%y baja el 5%. Conclusiones. Nuestro estudio refleja una alta adherencia de los participantes a la Dieta Mediterránea.
BACKGROUND: Guidelines recommend pharmacological treatment for systolic blood pressure (SBP) of 130 to 139 mm Hg in secondary prevention. However, uncertainty persists in primary prevention in low ...cardiovascular risk patients (CVR). METHODS: Cohort study representative of the general population of Albacete/Southeast Spain. We examined 1029 participants with untreated blood pressure and free of cardiovascular disease, followed-up during 1992 to 2019. Cox regression modeled the association of SBP with cardiovascular morbidity and mortality (outcome-1) and cardiovascular morbidity and all-cause mortality (outcome-2). RESULTS: Participants’ mean age was 44.8 years (53.8%, women; 77.1% at low-CVR); 20.3% had SBP 120 to 129; 13.0% 130 to 139 at low-CVR and 3.4% at high-CVR; and 27.4% ≥140 mm Hg. After a 25.7-year median follow-up, 218 outcome-1 and 302 outcome-2 cases occurred. Unadjusted hazard ratios of outcome-1 for these increasing SBP categories (versus <120) were 2.72, 2.27, 11.54, and 7.52, respectively; and 2.69, 2.32, 10.55, and 7.34 for outcome-2 (all P <0.01). After adjustment for other risk factors, hazard ratio (95% CI) of outcome-1 were 1.49 (0.91–2.44), 1.65 (0.94–2.91, P =0.08), 1.36 (0.72–2.57), and 1.82 (1.15–2.88), respectively, and 1.39 (0.91–2.11), 1.69 (1.05–2.73), 1.09 (0.63–1.88), and 1.64 (1.11–2.41) for outcome-2. Compared with 130 to 139 at low-CVR, hazard ratio for 130 to 139 at high-CVR was 4.85 for outcome-1 ( P <0.001) and 4.43 for outcome-2 ( P <0.001). CONCLUSIONS: In this primary prevention population of relatively young average age, untreated SBP of 130 to 139 mm Hg at low-CVR had long-term prognostic value and might benefit from stricter SBP targets. High-CVR patients had nonsignificant higher risk (limited sample size) but 4-fold greater risk when compared with low-CVR. Overall, results indicate the importance of risk stratification, supporting risk-based decision-making.
In Spain, data based on large population-based cohorts adequate to provide an accurate prediction of cardiovascular risk have been scarce. Thus, calibration of the EuroSCORE and Framingham scores has ...been proposed and done for our population. The aim was to develop a native risk prediction score to accurately estimate the individual cardiovascular risk in the Spanish population.
Seven Spanish population-based cohorts including middle-aged and elderly participants were assembled. There were 11800 people (6387 women) representing 107915 person-years of follow-up. A total of 1214 cardiovascular events were identified, of which 633 were fatal. Cox regression analyses were conducted to examine the contributions of the different variables to the 10-year total cardiovascular risk.
Age was the strongest cardiovascular risk factor. High systolic blood pressure, diabetes mellitus and smoking were strong predictive factors. The contribution of serum total cholesterol was small. Antihypertensive treatment also had a significant impact on cardiovascular risk, greater in men than in women. The model showed a good discriminative power (C-statistic=0.789 in men and C=0.816 in women). Ten-year risk estimations are displayed graphically in risk charts separately for men and women.
The ERICE is a new native cardiovascular risk score for the Spanish population derived from the background and contemporaneous risk of several Spanish cohorts. The ERICE score offers the direct and reliable estimation of total cardiovascular risk, taking in consideration the effect of diabetes mellitus and cardiovascular risk factor management. The ERICE score is a practical and useful tool for clinicians to estimate the total individual cardiovascular risk in Spain.
En España no existen unas cohortes poblacionales suficientemente grandes para hacer predicciones precisas del riesgo cardiovascular. Las ecuaciones de Framingham y EuroSCORE calibradas son las más utilizadas en España. El objetivo es desarrollar la primera ecuación de predicción autóctona para estimar con precisión el riesgo cardiovascular individual en España.
Análisis conjunto de siete cohortes españolas de población de mediana edad y anciana. La población del estudio —11.800 personas (6.387 mujeres)— aportó un total de 107.915 personas-año de seguimiento y 1.214 eventos cardiovasculares (633 de ellos, mortales). Se efectuó un análisis de regresión de Cox para examinar la contribución de los diferentes factores al riesgo de cualquier evento cardiovascular (mortal y no mortal).
La edad fue el principal factor de riesgo de eventos cardiovasculares. La presión arterial sistólica, la diabetes mellitus, el tabaquismo y el tratamiento antihipertensivo fueron factores predictivos fuertemente asociados con el riesgo cardiovascular. En cambio, la contribución del colesterol total sérico fue pequeña, especialmente en los mayores de 70 años. El modelo final de riesgo mostró un buen poder discriminatorio (estadístico C=0,789 en varones y C=0,816 en mujeres).
ERICE es una nueva ecuación de riesgo cardiovascular genuinamente española obtenida a partir del riesgo concurrente individual de los participantes en varias cohortes. La ecuación ERICE ofrece una estimación directa y fiable del riesgo cardiovascular total teniendo en cuenta factores como la diabetes mellitus y el tratamiento farmacológico de los factores de riesgo cardiovascular, habitualmente no incluidos en otras ecuaciones.
