Evolución de la prevalencia de los factores de riesgo y del riesgo cardiovascular global en población mayor de 18 años de la provincia de Albacete (1992-94 a 2004-06)

Fundamento: Establecer estrategias de prevencion de la enfermedad cardiovascular implica conocer su epidemiologia y evolucion en el tiempo. El objetivo del estudio es conocer las prevalencias de los factores de riesgo y del riesgo cardiovascular en dos momentos de seguimiento de una poblacion general adulta. Metodos: Dentro de un estudio longitudinal y prospectivo con poblacion general seleccionada al azar seguida durante 12 anos (1992-94 a 2004-2006) se hacen dos analisis trasversales al inicio y en el ultimo corte de seguimiento. La poblacion objeto de estudio fueron personas mayores de 18 anos censadas en la provincia de Albacete. Muestreo aleatorio, estratificado y bietapico. Tamano muestral 2.121 y 1.577 sujetos en cada uno de los cortes. Se hizo anamnesis, exploracion fisica, medida de presion arterial, electrocardiograma y extraccion de sangre venosa. Las variables estudiadas fueron: edad, sexo, antecedentes personales y familiares, factores de riesgo y riesgo cardiovascular global. Resultados: En el primer examen acudieron a la cita 1.322 sujetos (edad media 48,2 anos. 53,6% mujeres) y 997 en el segundo (edad media 52,8 anos. 56,7% mujeres). Hubo un aumento en la prevalencia de hipertension (32,7% a 41,2%) diabetes mellitus (9,8 a 11,4%), obesidad (27,8 a 34,3%) e hipercolesterolemia (47,5 a 53,5%), una disminucion de fumadores (32,6 a 23,7%), de valores medios de presion arterial (132/81 a 129/73 mmHg), glucemia (100,8 a 92,8 mg/dl) y col-LDL (128,7 a 116,7 mg/dl) y un descenso del riesgo cardiovascular con Framingham (10,8% a 8,2%) y Score (2,3% a 1,6%). Conclusiones: En los ultimos anos se observa un aumento en la prevalencia de factores de riesgo (hipertension, diabetes e hipercolestrerolemia), un mejor control de los mismos, una menor prevalencia de fumadores y menor riesgo cardiovascular en la poblacion.BACKGROUND To establish strategies for prevention of cardiovascular disease implies to know its epidemiology and evolution in time. The objective of this study is to know the prevalence of risk factors and cardiovascular risk in two moments during the following of a grownup general population. METHODS Study of cohorts, followed at random selected general population during 12 years (1992-94 to 2204-06). Two transversal studies were made, one at the beginning and the other one at the end of this follow-up. The population in this study was 18 years and older registered in the province of Albacete. Random sampling, stratified and two-stage. The sample size for the first cut was 2121 subjects and for second one 1577. One specific anamnesis was made, physical examination, measurement of blood pressure, electrocardiogram and extraction of venous blood. The studied variables were: age, sex, personal and familiar antecedents, risk factors and global cardiovascular risk. RESULTS 1322 subjects went to the appointment for the first examination (mean age 48.2 years. 53.6% women) and 997 for the second (mean age 52.8 years. 56.7% women). Has Increased the prevalence of hypertension (32.7% to 41,2%), diabetes (9,8 to 11,4%), obesity (27,8 to 34,3%) and hypercolesterolemia (47,5 to 53,5%), whereas smokers have decreased (32,6 to 23,7%) and have handicapped the average values of arterial pressure (132/81 to 129/73 mmHg), glycaemia (100,8 to 92,8 mg/dl) and LDL-cholesterol (128,7 to 116,7 mg/dl) and also a lowering of cardiovascular risk with Framingham (10,8% to 8,2%) and Score (2,3% to 1,6%). CONCLUSIONS In the last years an increasing prevalence of risk factors has been seen (hypertension, diabetes and hypercolesterolemia), a better control of them, and lower prevalence of smoking and cardiovascular risk in the population has also be seen.BACKGROUND To establish strategies for prevention of cardiovascular disease implies to know its epidemiology and evolution in time.

Valoración del colesterol no HDL como predictor de episodios cardiovasculares no mortales en una cohorte prospectiva de origen poblacional

INTRODUCTION Non-HDL cholesterol (non-HDL-C) is becoming relevant both in its participation in cardiovascular risk assessment and as a therapeutic target. The objective of the present study was to assess the independent predictive capacity of both non-HDL-C and LDL-C (the main priority in dyslipidemias to reduce cardiovascular risk), in cardiovascular morbidity in a population-based sample. METHODS A prospective cohort study involving 1186 individuals in the non-HDL-C group and 1177 in the LDL-C group, followed for 10.7years (SD=2.2), who had not had any previous cardiovascular event. The predictor variables included in the adjustment were: gender, age, arterial hypertension, diabetes mellitus, smoker status and non-HDL-C in one group. In the other group, consisting of patients presenting TG levels of 400mg/dL, non-HDL-C was replaced by LDL-C. Survival curves (Kaplan-Meier) were calculated and two Cox regression models were applied, one for each group. RESULTS Non-HDL-C group presented 6.2% of non-fatal cardiovascular episodes during follow-up and the LDL-C group 6.0%. After adjustment, for each 30mg/dL increase in non-HDL-C, the incidence of new non-fatal cardiovascular events increased by 31% (HR=1.31, 95%CI: 1.06-1.61; P=.018) and in the LDL-C group by 27% (HR=1.27, 95%CI: 0.97-1.61, P=.068). CONCLUSIONS After a follow-up of 10.7years, non-HDL-C has been shown in our population as a prognostic factor of non-fatal cardiovascular disease, but not LDL-C, although its HR is close to statistical significance.

Relación entre el proceso inflamatorio y la mortalidad de origen cardiovascular y por todas las causas en un estudio de cohortes prospectivo de base poblacional

INTRODUCTION Inflammation is present in every stage of the atherosclerosis process, therefore, inflammation hallmarks such as the fibrinogen can be related to the complications in which it intervenes, mortality is one of them. The objective of this study is to assess the association of the fibrinogen with all-cause mortality in men from general population sample obtained by random sampling in the Spanish region of Albacete. METHODS A total of 506men without cardiovascular events with 10.6years (SD=2.3) of follow-up, volunteered to participate in a prospective cohort study. The assessment of the fibrinogen as a predictor variable has been calculated after adjusting it by age, hypertension, diabetes mellitus, obesity, total cholesterol, HDL-cholesterol/triglycerides ratio, and smoking habit applying a Cox regression model. The adjustment has been made by adding the fibrinogen to the model, as a qualitative variable (<400 and ≥400mg/dl). RESULTS The average age of the participants was 46.6years old (DE=16.8). After the adjustment, the hyperfibrinogenemia (≥400mg/dl) showed a hazard ratio (HR) for all-cause mortality of 1.85 (95%CI: 1.05-3.26) and for cardiovascular mortality HR=2.69 (95%CI: 1.09-6.63). CONCLUSIONS In men without cardiovascular events of our study, fibrinogen was showed as an independent predictor of all-cause mortality and cardiovascular mortality.

Effect of Three Methods of Approaching Obesity in Long- Term Weight Loss

Objective: To analyze the effect on weight reduction in overweight and obese patients through three intervention methods. Material and methods: Prospective, randomized, multicentric intervention study in overweight and obese patients with a 12-month follow-up. Patients were randomized into three intervention groups: Obesity motivational intervention with previously trained nurse (G1), lower intensity consultation, no motivational group, digital platform support (G2), and a third group that received a recommendation to lose Weight and follow-up in primary care consultation (G3). Weight, height, BMI, abdominal waist circumference, Lipid Parameters, Blood Pressure and Blood Glucose were collected. Results: The study enrolled 176 patients, of whom 60 were randomized to Group 1, 61 to Group 2 and 55 to Group 3. 58% of the populations were women and 42% men, being therefore the global ratio between men and women from 1 to 2.65. In all three groups the weight decreased in each visit, with an overall mean reduction at the end of the study of 3.9 kg. It can be seen how the three groups reduce total cholesterol, although the G1 with motivational intervention reduces it significantly more with respect to G2 and G3. On the other hand Triglycerides are significantly reduced by the two study groups. And HDL-C is increased in all three groups. Conclusions: The three groups managed to reduce weight, although the group with motivational intervention and telemedicine showed significant differences. *Corresponding author: Pedro J.

Efecto sobre los parámetros lipídicos de una intervención para reducir peso en pacientes con sobrepeso y obesidad

OBJECTIVE To assess the effect on lipid parameters most associated with excess weight (triglycerides [TG], cholesterol, and high density lipoprotein [HDL-C]) of an intervention to reduce weight in overweight and obese patients. METHODS A randomised, controlled, double blind clinical trial, with three groups, and a follow-up of 12 months. Patients included in the study were randomised into three intervention groups: Obesity motivational intervention group with previously trained nurse (G1), lower intensity consultation, non-motivational group, with digital platform support (G2), and a third group that received a recommendation to lose weight and usual follow-up (G3). The anthropometric variables measured were height, weight, and abdominal/waist circumference, and laboratory results, total cholesterol, TG and HDL cholesterol). RESULTS The study include 176 patients, of whom 60 were randomised to G1, 61 to G2, and 59 to G3. All groups significantly decreased body weight at the end of the study, with a decrease in G1 (-5.6kg), followed by G2 (-4.3kg), and G3 (-1.7kg), with an overall mean loss of -3.9kg. There was a also significant decrease (P<.05) in total cholesterol and TG, and an increased HDL-C. These changes were more marked in the G1 group (the group that lost more weight). The clinical relevance indicators that were significant were: in the case of TG: G1/G3: relative risk: 1.42 (95% CI: 1.11-1.80); relative risk reduction: 41.7% (11.4-80.2); absolute risk reduction: 25% (9.2-40.8) and NNT: 5 (3-11). In the case of G1/G2 HDL-C: relative risk: 1.32 (1.07-1.63); relative risk reduction: 32.2% (7.4-62.6); absolute risk reduction: 21.1% (6.4-35.8) and NNT: 5 (3-16). CONCLUSIONS Weight reduction is accompanied by favorable changes in the lipid parameters related to overweight and obesity, being more intense the greater the weight loss.
