Purpose: To determine the relationship between self-reported physical activity and the components of premorbid metabolic syndrome in patients treated in primary care according to sex., Methods: Cross-sectional descriptive study conducted on a sample of 2,359 patients without cardiovascular disease or diabetes, included in the cohort of the IBERICAN study. Using ANOVA models and adjusting for age, economic status, employment situation, level of education, adherence to a Mediterranean diet, tobacco use and alcohol consumption, we estimated the association of the variables blood pressure, triglycerides, HDL cholesterol, blood glucose and waist circumference with the self-reported level of physical activity (sedentary, moderate, high, very high). The analyses were performed stratifying by sex., Results: A total of 854 men and 1,505 women with no identified diseases were included. Women were more sedentary than men (p<0.004; OR = 1,35; IC95% = 1,10-1,65) and presented lower values in all the components of the metabolic syndrome, except for HDL-cholesterol, which was higher (p<0.001). The adjusted ANOVA model shows that diastolic blood pressure, triglycerides, fasting blood glucose, and waist circumference were significantly lower the higher the level of physical activity in both men and women (p<0.05)., Conclusions: Patients served in primary care clinics without diabetes or cardiovascular disease and with high levels of physical activity showed better metabolic syndrome profiles. Given that women are more sedentary, gender approaches are needed in the promotion of physical activity to prevent metabolic syndrome and cardiovascular disease., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2025 Micó-Pérez et al.

(1) Background: Urate levels lower than the classical cut-off point for defining hyperuricemia can increase cardiovascular risks. The aim of this study is to determine if there is a relationship between different urate levels and classic cardiovascular risk factors (CVRFs). (2) Methods: A cross-sectional study of the inclusion visits of the patients recruited to the IBERICAN study was conducted. The patients were classified into quartiles according to their distribution of urate levels and separated by sex; the three lower points corresponded to normal levels of urate, and the highest quartile was determined according to the classical definition of HU. Multivariate analysis models, adjusted for epidemiological variables, were used to analyze the association of urate levels with CVRFs. (3) Results: The presence of CVRFs was higher across the quartiles of urate, with a continuous increase along the quartiles in both sexes in accordance with body mass index ( p < 0.01), waist circumference ( p < 0.01), blood pressure ( p < 0.01), and LDL cholesterol ( p < 0.01). The CV risk estimated by SCORE was associated with an increase along the quartiles in women ( p = 0.02). (4) Conclusions: A progressive increase in the frequency of CVRFs, as well as in their levels, was observed across the quartiles of uricemia, which reflects an increase in the CVRs associated with uricemia.

Introduction: There are few data about the optimal use of natriuretic peptides (NP) in the Primary Care (PC) setting. The aim to assess how, through a common coordinated PC-hospital care pathway, the use of NPs in patients with suspected heart failure (HF) is improved., Material and Methods: Analytical, experimental, prospective, non-randomized study. An intervention group composed of 22 PC physicians from 2 health centers is provided with face-to-face training and a consensual protocol is attached with a cut-off point of NT-proBNP> 300 pg/mL as pathological. The control group is made up of the rest of PC physicians in the healthcare area. The aim is to compare the use and results of PN in both groups. Propensity analysis is performed so thar the patient populations with requested PN are comparable., Results: From June 2021 to March 2022, NP was requested in 103 and 105 patients in the intervention/control groups. Both populations were similar, with equal HF risk. Symptomatology was present in 100% of intervention vs 41% of asymptomatic patients in the control group (p <0.001). ECG was performed in 100% vs 33.3%, p <0.001. Optimal NP indication in 76.7% vs 29.5%, p <0.001. In the intervention group more patients with NT-proBNP> 300 pg/mL are referred to cardiology consultations (76.6% vs 27.2%, p 0.001)., Conclusion: The optimal indication for NP and its interpretation as a diagnostic tool for HF, in the PC setting seems not to be appropriate, but improvable with a coordinated and multidisciplinary intervention approach., (Copyright © 2024 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Background: The management in primary care (PC) of the patients with Heart Failure (HF) is different from the management hospital, in a special way compared to cardiology departments., Objective: To define the characteristics in both phenotypes of HF in prevalent and incident cases of HF in patients recruited in a large PC sample., Methods: We proposed a and longitudinal analyses, in patients of the IBERICAN cohort, that recruited 8,066 patients in the Spanish primary care system, with 15,488 patients-years of follow-up. Of them, 252 patients (3.1%) had diagnoses of HF. HF was classified according to the 2014 guidelines in two groups: HF with a reduced eject fraction or HFrEF (LVEF < 50%) and HF with preserved eject fraction or HFpEF (LVEF ≥ 50%). Recommended treatment was defined as the patient receiving drug treatment with Renin-Angiotensin-System (RAS) blockers with beta-blockers and, optionally, spironolactone. The incidence of new cases of HF was calculated in the 7,814 patients without HF in the inclusion visit. Finally, we analysed which variables associated the onset new cases and get the hazard ratio (HR) with the confidence interval at 95% ([95%CI]). Clinical trials register: NCT02261441 (02/05/2017)., Results: The HFpEF was the most frequent phenotype in prevalent cases (61.1%) and incident cases (73.9%). Patients with HFrEF had a higher prevalence of coronary heart disease (p = 0.008) and PAD (p = 0.028), and no statistically significant differences was observed in the therapeutic groups used between both groups. The incidence of HF was 12.8 cases/1000 inhabitants/year, 35.6% of them was diagnosed in PC. The renin-angiotensin system blockers were more used in PC (60%) and beta-blockers (100%) and spironolactone (60%) in hospital. The female sex showed a protective effect for incident cases (0.51 [0.28-0.92]); and AF (HR [95%CI]: 2.90 [1.51-5.54]), coronary heart disease (HR [95%CI]: 2.18 [1.19-4.00]) and hypertension (HR [95%CI]: 1.91 [1.00-3.64]) increased the risk of developing HF., Conclusions: HF phenotype more frequent and incident in PC was the HFpEF, but only one third of them are diagnosed in PC level. The female sex showed a protective effect and atrial fibrillation, ischaemic heart disease and hypertension increased the risk of develop HF., (© 2024. The Author(s).)

Introduction: Elevated pulse pressure (ePP) is an independent marker of cardiovascular risk (CVR) in people older than 60, and a functional marker of subclinical target organ damage (sTOD) which can predict cardiovascular events in patients with hypertension (HTN), regardless of sTOD., Objective: To evaluate the prevalence of ePP in adult population seen in primary care and its association with other vascular risk factors, sTOD and with cardiovascular disease (CVD)., Materials and Methods: Observational multicentre study conducted in Spain (8,066 patients, 54.5% women) from the prospective cohort study IBERICAN recruited in Primary Care. Pulse pressure (PP) was defined as the difference between the systolic blood pressure (SBP) and the diastolic blood pressure (DBP) ≥60 mmHg. Adjusted (for age and sex) ePP prevalence were determined. Bivariate and multivariate analyses of the possible variables associated with ePP were carried out., Results: The mean of PP was 52.35 mmHg, and was significantly higher ( p  < 0.001) in patients with HTN (56.58 vs. 48.45 mmHg) The prevalence of ePP adjusted for age and sex was 23.54% (25.40% men vs. 21.75% women; p  < 0.0001). The ePP prevalence rates increased linearly with age ( R 2  = 0.979) and were significantly more frequent in population aged ≥65 than in population aged <65 (45.47% vs. 20.98%; p  < 0.001). HTN, left ventricular hypertrophy, low estimated glomerular filtration rate, alcohol consumption, abdominal obesity, and CVD were independently associated with ePP. 66.27% of patients with ePP had a high or very high CVR, as compared with 36.57% of patients without ePP (OR: 3.41 [95% CI 3.08-3.77])., Conclusions: The ePP was present in a quarter of our sample, and it was increased with the age. Also, the ePP was more frequent in men, patients with HTN, other TOD (as left ventricular hypertrophy or low estimated glomerular filtration rate) and CVD; because of this, the ePP was associated a higher cardiovascular risk. In our opinion, the ePP is an importer risk marker and its early identification lets to improve better diagnostic and therapeutic management., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Moyá-Amengual, Ruiz-García, Pallarés-Carratalá, Serrano-Cumplido, Prieto-Díaz, Segura-Fragoso, Cinza-Sanjurjo and the researchers of the IBERICAN study.)

The role of uric acid levels in the cardiovascular continuum is not clear. Our objective is to analyze the prevalence of hyperuricemia (HU) and its association with cardiovascular risk factors (CVRF), subclinical target organ damage (sTOD), and cardiovascular diseases (CVD). We evaluated the prevalence of HU in 6.927 patients included in the baseline visit of the IBERICAN study. HU was defined as uric acid levels above 6 mg/dL in women, and 7 mg/dL in men. Using adjusted logistic regression models, the odds ratios were estimated according to CVRF, sTOD, and CVD. The prevalence of HU was 16.3%. The risk of HU was higher in patients with pathological glomerular filtration rate (aOR: 2.92), heart failure (HF) (aOR: 1.91), abdominal obesity (aOR: 1.80), hypertension (HTN) (aOR: 1.65), use of thiazides (aOR: 1.54), left ventricular hypertrophy (LVH) (aOR: 1.36), atrial fibrillation (AFIB) (aOR: 1.29), and albuminuria (aOR: 1.27). On the other hand, being female (aOR: 0.82) showed a reduced risk. The prevalence of HU was higher in men, in patients presenting CVRF such as HTN and abdominal obesity, and with co-existence of LVH, atrial fibrillation (AFIB), HF, and any form of kidney injury. These associations raise the possibility that HU forms part of the early stages of the cardiovascular continuum. This may influence its management in Primary Healthcare because the presence of HU could mean an increased CV risk in the patients.

Objective: To determine the prevalence of hypotension and associated factors in hypertensive patients treated in the Primary Care setting., Materials and Methods: A cross-sectional, descriptive, and multicentre study was conducted with a total of 2635 general practitioners consecutively including 12,961 hypertensive patients treated in a Primary Care setting in Spain. An analysis was performed on the variables of age, gender, weight, height, body mass index, waist circumference, cardiovascular risk factors (diabetes, dyslipidaemia, smoking, obesity, sedentary lifestyle), fasting plasma glucose, complete lipid profile, as well as the presence of target organ damage (left ventricular hypertrophy, microalbuminuria, carotid atherosclerosis) and associated clinical conditions. Hypotension was defined as a systolic blood pressure less than 110mmHg or a diastolic blood pressure less than 70mmHg. A multivariate analysis was performed to determine the variables associated with the presence of hypotension., Results: The mean age was 66.2 years, and 51.7% of patients were women. The mean time of onset of hypertension was 9.1 years. A total of 13.1% of patients (95% confidence interval 12.4-13.6%) had hypotension, 95% of whom had low diastolic blood pressure. The prevalence of hypotension was higher in elderly patients (25.7%) and in those individuals with coronary heart disease (22.6%). The variables associated with the presence of hypotension included a history of cardiovascular disease, being treated with at least 3 antihypertensive drugs, diabetes, and age., Conclusions: One out of 4-5 elderly patients, or those with cardiovascular disease, had hypotension. General practitioners should identify these patients in order to determine the causes and adjust treatment to avoid complications., (Copyright © 2019 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Background and Objective: Cardiovascular diseases (CVD) are the leading cause of death in Spain, and although the incidence rates have been declining for years due to improvements in prevention and treatment, there is still room for further reduction. Primary Care has a leading role in the prevention and control of these diseases. Determining the prevalence and incidence of cardiovascular risk factors and cardiovascular diseases in the Spanish adult population attended in Primary Care is the objective of the study to identify the Spanish population at cardiovascular and renal risk (IBERICAN)., Material and Methods: A prospective cohort study was conducted using a consecutive non-probabilistic sampling population between 18 and 85 years that attended Primary Care centres between April 1, 2014 and October 31, 2018. By reviewing the medical history, laboratory results, and medical visits, the Primary Care physicians collected socio-demographic information, personal and family history of the patients, as well as prevalence and incidence of cardiovascular risk factors and cardiovascular and renal disease. The incidents and associated factors will be estimated using proportional risk models of Cox and Kaplan-Meier Curves., Results: A total of 8,066 patients have been recruited by 531 Primary Care physicians from all Autonomous Communities of Spain as part of the IBERICAN cohort, with the exception of Ceuta. The mean age of the cohort is 57.9 years with 54.5% women. Obesity, dyslipidaemia, and hypertension are the most prevalent cardiovascular risk factors. There was a history of CVD in16.3%, and 25.5% had a subclinical organ lesion., Conclusion: The IBERICAN study is a cohort of people treated in Primary Care that expects to provide relevant information on the factors that determine the incidence of cardiovascular and renal disease in Spain., (Copyright © 2019 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Objectives: To analyse the prevalence of obesity and its association with other cardiovascular risk factors and cardiovascular disease in a sample of patients from the (Identification of the Spanish population at cardiovascular and renal risk) IBERICAN study., Material and Methods: Analysis of the inclusion visit of the first 5,013 patients of the IBERICAN longitudinal, observational, and multicentre study in which individuals aged 18 to 85 years were included in Primary Care Clinics in the different regions of Spain. In this work obesity was defined as a body mass index ≥ 30kg/m 2 ., Results: The prevalence of obesity was 35.7% (95% CI: 35.0-36.4%), of which 36.6% were men and 34.9% were women (P=0.214), and significantly increasing with age (0.001). The obesity had the associated higher prevalence of hypertension (62.8% vs. 39.4%, P<001), dyslipidaemia (56.9% vs. 47.1%, P<0.001), sedentary lifestyle (40.6% vs. 24.6%, P<.001), diabetes (27.5% vs. 14.8%, P<.001), hyperuricaemia (23.6% vs. 12.7%, P<.001), subclinical organ injury (33.7% vs. 26.5%, P<.001) and cardiovascular disease (21.2% vs. 15.3%, P<.001). The multivariate analysis showed that the variables associated with obesity were: arterial hypertension (P<.001), hyperuricemia (P<.001), sedentary lifestyle (P<.001), diabetes mellitus (P<0.001), age (P<0.001), low educational level (P<0.001) and lower consumption of tobacco (P<0.001)., Conclusions: The analysis of the IBERICAN study shows that approximately one third of the analysed population meets criteria of obesity and cardiovascular risk factors. Target organ damage and cardiovascular disease were more frequent in obese patients., (Copyright © 2018. Publicado por Elsevier España, S.L.U.)

Objectives: To determine the prevalence and incidence of cardiovascular risk factors in Spain, as well as cardiovascular events, in Spanish adult population attended in primary care., Methodology: IBERICAN is a longitudinal, observational, multicenter study in which patients aged 18 to 85years attended in primary care health center in Spain are being included. The obtained cohort will be followed annually for at least 5years. The estimated final sample is 7,000 patients. The baseline characteristics of the second cut (n=3,042) are presented., Results: The mean age of the subjects included is 57.9±14.6 years, and 55.5% are women. 54.9% live in urban habitat, and 57.3% have primary education. 50.3% had dyslipidemia, 47.4% hypertension, 29.7% physical inactivity, 28.2% abdominal obesity and 19% diabetes mellitus. The degree of control of hypertension, dyslipidemia and type2 diabetes was 58.5%, 25.8% and 75.9%. 28.2% have criteria for metabolic syndrome. 15.6% of patients had previous cardiovascular disease. 7.8% have a history of coronary heart disease, a glomerular filtration rate <60ml/min (CKD-EPI) 8.4%, microalbuminuria 9.6%, atrial fibrillation 5.5%, stroke 4.6%, and heart failure 2.9%., Conclusions: Although the population treated in primary care is relatively young, the high prevalence of risk factors, their poor control and the existence of previous cardiovascular disease will determine the impact on the prognosis of the cohort., (Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Aims: To determine the differences between regions in the level of control of patients with non-valvular atrial fibrillation treated with vitamin K antagonists, included in the PAULA study., Methods: Observational, and coss-sectional/retrospective study, including 139 Primary Care physicians from 99 Health Care centres in all autonomous communities (except La Rioja). Anticoagulation control was defined as the time in therapeutic range assessed by either the direct method (poor control <60%), or the Rosendaal method (poor control <65%)., Results: A total of 1,524 patients were included. Small differences in baseline characteristics of the patients were observed. Differences in the percentage of time in therapeutic range were observed, according to the Rosendaal method (mean 69.0±17.7%), from 78.1%±16.6 (Basque Country) to 61.5±14% (Balearic Islands), by the direct method (mean 63.2±17.9%) from 73.6%±16.6 (Basque Country) to 57.5±15.7% (Extremadura). When comparing regions, in those where the Primary Care physicians assumed full control without restrictions on prescription, the percentage of time in therapeutic range by the direct method was 63.89 vs. 60.95% in those with restrictions (p=.006), by Rosendaal method, 69.39% compared with 67.68% (p=.1036)., Conclusions: There are significant differences in the level of control between some regions are still inadequate. Regions in which the Primary Care physicians assumed the management of anticoagulation and without restrictions, time in therapeutic range was somewhat higher, and showed a favourable trend for better control. These findings may have clinical implications, and deserve consideration and specific analysis., (Copyright © 2016 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Objective: To determine the prevalence and clinical and epidemiological characteristics of Primary Care patients with resistant hypertension (RHT) in Spain., Patients and Methods: A cross-sectional multicenter study was conducted on hypertensive patients aged 18 or over and seen in a Primary Care clinic. RHT was considered as the presence of uncontrolled blood pressure in patients treated with at least 3 drugs, one of which is a diuretic., Results: Of the 12,961 hypertensive patients in the PRESCAP 2010 study, 962 (7.4%) fulfilled criteria for RHT, of whom 51% were women, and with a mean age (SD) 68.8 [11.4] years. Patients with RHT were older (68.80 [10.69] years vs. 66.06 [11.44] years, P<.001), had a higher prevalence of obesity (55.2 vs. 38.6%, P<.001), a higher waist circumference (103.90 [13.89] vs. 99.32 [13.69] cm, P<.001), and a higher prevalence of DM (48.3 vs. 29.5%, P<.001). The prevalence of target organ damage (73.0 vs. 61.4%, P<.001) and cardiovascular disease (46.7 vs. 26.8%, P<.001) were higher in patients with resistant hypertension. The multivariate analysis showed that the variables associated with resistant hypertension were the presence of cardiovascular disease, diabetes mellitus, sedentary life style, microalbuminuria, body mass index, duration of AHT, and triglycerides., Conclusions: The prevalence of RHT in Primary Care patients is related to inappropriate lifestyles, the presence of target organ damage, and cardiovascular disease., (Copyright © 2014 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

In the last year, several scientific societies have published guidelines for the management of arterial hypertension. In Spain, two clinical practice guidelines have had a strong impact and have been closely followed in the last few years: the first is the Guideline of the National Heart, Lung and Blood Institute, although their last report (JNC 7) was published in 2003; the second is the clinical practice guideline for the management of arterial hypertension of the European Society of Cardiology (ESC) and the European Society of Hypertension (ESH), whose latest version was published in 2007, although an update was published in 2009. A new ESC/ESH document, published in 2013, adopts a mainly educational stance, closely rooted in clinical practice. Many of the recommendations maintain the same criteria as previous guidelines. However, the new publication shows greater rigor and contains major contributions such as specification of the level of evidence and grade of recommendation for each recommendation, which was lacking in the previous guidelines of these societies. The document is both practical and easy to consult, consisting of 17 tables, 5 figures and 18 blocks of recommendations. The JNC 8 report, however, has a single objective: to respond to three questions that are considered a priority and which refer exclusively to drug therapy. Nine recommendations are made relating to these three questions., (Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Medicina Rural y Generalista (SEMERGEN). All rights reserved.)

Background and Objective: White coat effect (WCE) is one of the main bias that can affect office blood pressure (BP) measurement. Therefore, it is a factor must be considered in hypertensives to avoid mistakes in diagnosis and/or treatment. Employment of automated office BP (AOBP) devices could diminish that effect., Methods: Two studies were designed with the objective of evaluating differences between routinely office and AOBP measurements. WCE was also assessed. First, the TRUE-ESP study included normotensive and hypertensive patients attending specialized consultations at Cardiology, Nephrology, Internal Medicine, Endocrinology and Family Practice. Second, the TRUE-HTA study included hypertensives attending a protocoled Hypertension Unit, with a trained staff., Results: TRUE-ESP study included 300 patients, 76% being hypertensives. A significant difference between office BP and AOBP measurement (SBP/DBP 9.8±11.6/3.4±7.9 mmHg, P<.001) was observed. Percentage of patients gathering WCE criteria was 27.7%. TRUE-HTA study included 101 hypertensive patients. A significant difference between office BP and AOBP measurement (SBP/DBP 5.7±9.3/2.1±5.3 mmHg, P<.001) and activity period-ABPM (SBP/DBP 8.5±6.7/3.5±2.5 mmHg, P<.001) was observed. Percentage of WCE patients was 32.1%., Conclusions: Use of AOBP devices can contribute to decrease WCE and to improve accuracy of office BP measurement., (Copyright © 2011 Elsevier España, S.L.

Objective: We aimed to verify the level of blood pressure and glucose control and treatment in hypertensive diabetics seen in Primary Care Centres in Spain., Design: Descriptive study conducted on hypertensive diabetic patients who attended primary care centres for any reason., Location: Primary Care centres throughout Spain., Participants: The study included 6,777 patients., Measurements: Blood pressure, weight, height, waist circumference, blood analysis and treatment were recorded, Results: The mean age of the sample was 64.40 (11.50) years. Mean blood glucose was 141.8 (39) mg/dl, glycosylated haemoglobin was ≤7% in 45.9% of the sample, and blood pressure was under control (BP≤130/80 mmHg) in 9.8% of the patients studied. LDL Cholesterol was ≤100mg/dl in 25.3% of the sample. The drugs most used to control diabetes were; sulphonylureas 2259 patients (33.3%) and biguanides 3768 patients (55.6%). A total of 556 patients were on treatment with insulin, which represented 8.2% of the population studied. The drugs most used for hypertension were; diuretics in 3395 patients (50.1%) and angiotensin-converting enzyme inhibitors in 4053 patients (59.8%)., Conclusions: A large proportion of hypertensive diabetics are insufficiently controlled., (Copyright © 2010 Elsevier España, S.L.

Objective: Obesity is closely related to insulin-resistance (IR) but it is evaluated differently in the diverse definitions of the metabolic syndrome. The objective of this study was to verify the utility of different anthropometric measures to predict IR and to evaluate the best cut-off points., Subjects and Method: We performed a cross-sectional study of the general population aged 40 to 70 years old (n=2,143); a simple random sample of 305 non-diabetic persons was obtained. Sociodemographic data, physical examination and routine biochemical analysis with insulinemia were obtained. IR was defined by a HOMA index (Homeostasis Model Assessment) ≥2.9. To obtain the best variables to predict IR, a forward stepwise logistic regression was performed. Subsequently, a logistic equation was constructed and its predictive capacity was compared with the different anthropometric variables by the area under the ROC (receiver-operating characteristic) curve (AUC). The best cut-off points were established according to the Youden index., Results: Body mass index (BMI) and the waist/hip ratio ×100 were entered into the model, but age, sex, waist, hip and body surface were not. The logistic equation found: p(RI)=1/1+exp{-[-14.295]-[0.234×IMC]-[0.07×(waist/hip×100)]} showed good adjustment, and the probability calculated on the basis of this equation showed the greatest AUC overall and in both sexes, followed in women by BMI and by waist measurement in men, but without significant differences., Conclusions: No significant differences were found between the BMI, waist or hip measurements and the logistic model to predict IR., (Copyright © 2008 Sociedad Española de Endocrinología y Nutrición.
