Concordance between automated oscillometric measurement of ankle-brachial index and traditional measurement by eco-Doppler in patients without peripheral artery disease.

AIM: To evaluate the concordance between automated oscillometric measurement (WatchBP® Office ABI) of the ankle- brachial index (ABI) and the traditional measurement by eco-Doppler in a Spanish population without peripheral artery disease attended in primary care. METHODS: The ABI was determined by both methods in a general population aged ≥ 18 years, from the RICARTO study. The intraclass correlation coefficient was calculated to assess the concordance between both techniques and the Bland-Altman plot was determined to analyze the agreement between them. RESULTS: A total of 322 subjects (mean age 47.7 ± 16.0 years; 54.3% women) were included in the study. With regard to cardiovascular risk factors, 70.5% of subjects had dyslipidemia, 26.7% hypertension, 24.8% obesity, 8.4% diabetes and 25.5% were smokers. Mean ABI measured by eco-Doppler and the automated method were 1.17 ± 0.1 and 1.2 ± 0.1, respectively (mean differences - 0.03 ± 0.09; p < 0.001). The Pearson correlation coefficient and the intraclass correlation coefficient were in both cases 0.70. CONCLUSIONS: The automated oscillometric measurement of ABI is a reliable and useful alternative to conventional eco-Doppler determination in the general population without peripheral artery disease attended in primary care.

Prevalence of chronic kidney disease and associated factors in the Spanish population attended in primary care: Results of the IBERICAN study. / Prevalencia de la enfermedad renal crónica y factores asociados en la población asistida en atención primaria de España: resultados del estudio IBERICAN.

OBJECTIVES: To determine the prevalence of chronic kidney disease (CKD) and the factors associated with impaired renal function in the population attended in primary care (PC). PATIENTS AND METHOD: Cross-sectional and multicentre study carried out in the baseline patients of the IBERICAN study (Identificación de la poBlación Española de RIesgo CArdiovascular y reNal). CKD was considered with an estimated glomerular filtration (eGF) <60ml/min/1.73 m2 or elevated albuminuria (≥ 30mg/g). According to the eGF, the CKD was classified in six stages (1, 2, 3a, 3b, 4 and 5) and according to albuminuria in three stages (A1 or normal / slightly increased, A2 or moderately increased and A3 or severely increased). The clinical characteristics and the relationship of CKD with the main cardiovascular risk factors (CVRF) and other variables of interest were analysed using unconditional logistic regression. RESULTS: 7,895 patients were included (mean age 57.9±14.8 years; 54.5% women). 14.4% (95% CI: 13.6-15.1) had CKD; 16.1% (95% CI: 14.9-17.3) in men and 12.9% (95% CI: 11.9-14.0) in women. A continuous increase of the prevalence was observed with age (24.8% in≥65 years) and with CVFR aggregation. The variables that were most associated with the probability of suffering CKD were left ventricular hypertrophy (OR: 1.95; p <.001), diabetes (OR: 1.58; P<.001) and hypertension (OR: 1.56; P<.001). CONCLUSIONS: Fourteen out of every 100 patients included in the IBERICAN study have CKD. The prevalence of CKD affects a quarter of patients ≥ 65 years and increases exponentially with the aggregation of FRCV.

Prevalence of Chronic Heart Failure, Associated Factors, and Therapeutic Management in Primary Care Patients in Spain, IBERICAN Study.

BACKGROUND: The prevalence of chronic heart failure (CHF) in patients assisted in primary care is not well known. We investigated the prevalence of CHF, its associated factors, and its therapeutic management. METHODS AND FINDINGS: This was a cross-sectional, multicenter study conducted in primary care (PC) in baseline patients of the IBERICAN study (Identification of the Spanish Population at Cardiovascular and Renal Risk). CHF was defined as the presence of this condition in the medical history, classifying patients according to the type of ventricular dysfunction in CHF with preserved ejection fraction (pEF), or CHF with reduced ejection fraction (rEF). Clinical characteristics, relationship between CHF and main cardiovascular risk factors (CVRF), and drug treatments used according to ejection fraction (EF) were analyzed. RESULTS: A total of 8066 patients were included (54.5% women), average age (SD) was 57.9 (14.8) years, of which 3.1% (95% CI: 2.3-3.7) presented CHF, without differences between men and women. CHF with pEF (61.8%; 95% CI: 55.5-67.6) was more frequent in women, and CHF with rEF (38.1%; 95% CI: 33.2-45.5) (p = 0.028) was similar in both genders (65.9%; 95% CI: 57.1-73.4 vs. 57.3%; 95% CI: 47.7-65.8) (p = 0.188). A progressive increase of the prevalence with age (15.2% in ≥80 years) and with the aggregation of CVRF was observed. The most prescribed treatments were beta-blockers (54.7%) followed by angiotensin converting enzyme inhibitors (42.8%) and angiotensin II receptor antagonists (41.3%), without differences between pEF and rEF. The variables that are most associated with the probability of suffering CHF were a personal history of left ventricular hypertrophy (OR: 5.968; p < 0.001), of atrial fibrillation (OR: 3.494; p < 0.001), and of peripheral vascular disease (OR: 2.029; p < 0.001). CONCLUSIONS: Three in every 100 patients included in the IBERICAN study presented CHF, of which two thirds had pEF. The condition increased exponentially with age and aggregation of CVRF. We did not find any differences in drug treatment according to the type of ventricular dysfunction. The treatment of HF with rEF has much room for improvement.

[Vascular age in a sample of general population of the sanitary area of Toledo (Spain). RICARTO study]. / Edad vascular de una muestra de población general del área sanitaria de Toledo (España). Estudio RICARTO.

OBJECTIVE: To know the vascular age (VA) of a sample of general population included in the RICARTO study. PATIENTS AND METHOD: Epidemiological study of the general population aged ≥18 from the Health Area of Toledo, based on the health card database. VA was calculated from the absolute cardiovascular risk (CVR) estimated with the Framingham and SCORE equations (type2 diabetes increased CVR in SCORE 2-fold in men and 4-fold in women). Patients with cardiovascular or renal disease were excluded. An ANCOVA analysis was conducted to adjust and compare the mean of VA by age and sex. RESULTS: 1,496 subjects (53.54% women) were analyzed. Mean (SD) age was 48.77 (14.89) years old and. Mean VA was 51.37 (19.13) with Framingham equation and 57.09 (17.63) years old with SCORE equation. VA was significantly higher in men, low education level, arterial hypertension, dyslipidemia, hypertriglyceridemia, diabetes mellitus, abdominal obesity, general obesity, smoking and in individuals with 5CVR factors vs none (P<.001 in all). Higher differences (Cohen's D >0.5) were found in non-diabetic vs diabetic people (1.58 Framingham; 2.44 SCORE), normotensive vs hypertensive subjects (1.64 Framingham; 1.19 SCORE), and non-dyslipidemia vs presence of dyslipidemia (0.95 Framingham; 0.66 SCORE). CONCLUSIONS: VA of our sample is two and a half years older than chronological one with Framingham equation and more than eight years with SCORE equation. Control of CVR factors is the key to get a VA closer to real and to obtain a better cardiovascular health in the population.

Cardiovascular risk and blood pressure control in a Spanish hypertensive population attended in a Primary Care setting. Data from the PRESCAP 2006 study.

AIMS: To analyse the cardiovascular risk of a broad sample of hypertensive patients and to examine whether there are differences in blood pressure control and associated factors according to the different cardiovascular risk categories. MAJOR FINDINGS: A total of 10,520 patients > or = 18 years old were included (mean age 64.6+/-11.3 years; 53.7% women). In this cohort, 3.3% were average risk, 22.6% low added risk, 22.2% moderate added risk, 33.5% high added risk and 18.4% very high added risk. Blood pressure was controlled in 41.4% (95% CI 40.5-42.4) of the total population, in 91.7% of patients with low added risk, in 19.4% with moderate added risk, in 27.4% with high added risk and in 6.8% with very high added risk. Diabetes was the factor most strongly associated with poor blood pressure control in patients with high to very high added risk (OR=7.2; p<0.0001). PRINCIPAL CONCLUSION: More than half of the hypertensive patients treated in primary health care have a high or very high added cardiovascular risk. In these patients, blood pressure control is inadequate and diabetes is associated with a sevenfold increase in the likelihood of poor blood pressure control.

The Gender Perspective Within the OFRECE Study: Differences in Health Care Among Patients Consulting for Chest Pain and/or Palpitations.

INTRODUCTION AND OBJECTIVES: To analyze differences between sexes in the clinical management of patients presenting with symptoms of chest pain and/or palpitations within a population-based study. METHODS: The OFRECE study included a random sample of 8400 individuals from the Spanish population aged 40 years and older; 1132 (13.5%) had previously consulted for chest pain and 1267 (15.1%) had consulted for palpitations and were included in the present study. We calculated both the crude and adjusted odds ratios (OR) of undergoing certain tests and the results of consultations by sex. Adjustment was performed by classic cardiovascular risk factors, a personal history of cardiovascular disease, and a diagnosis of stable angina or atrial fibrillation confirmed in the OFRECE study in each case. RESULTS: No differences were observed in history of consultation for chest pain between women and men (13% vs 14.1%; P=.159) but differences were found in palpitations (19% vs 10.4%, respectively; P <.001). Women who had previously consulted for chest pain underwent fewer echocardiograms (32.5% vs 45.3%, respectively; P <.001), were less frequently referred to a cardiologist (49.1% vs 60.1%; P <.001), were less often admitted to hospital (20.1% vs 39.4%; P <.001), and less frequently received a confirmed diagnosis (60.9 vs 71, 9; P <.001). After full adjustment, all differences decreased and become nonsignificant echocardiograms: adjusted OR, 0.81; 95%CI, 0.60-1.09; referral to a cardiologist: adjusted OR, 0.86; 95%CI, 0.63-1.16; hospital admission: adjusted OR, 0.76; 95%CI, 0.54-1.09). For palpitations, crude differences were smaller and all became nonsignificant after adjustment. CONCLUSIONS: This study does not confirm the existence of sex-related bias in the management of chest pain and palpitations. However, such bias cannot be completely ruled out in diagnoses confirmed within the OFRECE study, which might limit its ability to detect sex-related differences in health care.

Mean Blood Pressure of the General Population with the Mean of Three Measurements Versus the Mean of the Second and Third Measurements. Ricarto Study.

INTRODUCTION: Our aim was to determine the difference between measuring blood pressure (BP) with the mean of three determinations versus the mean of the second and the third determinations in a random general population sample. METHODS: Epidemiological study of the general population aged ≥ 18 from the Health Area of Toledo (Spain), based on the health card database. Three readings of systolic and diastolic BP were taken with validated oscillometric devices OMRON HEM-907. The mean of the three readings was compared with the mean of the second and third readings after discarding the first measurement. We analyzed age, sex, BMI, abdominal obesity, dyslipidemia, diabetes mellitus, smoking and sedentary lifestyle. A descriptive study was conducted, as well as the agreement in the diagnosis of hypertension. RESULTS: 1532 subjects were analyzed (mean age 49.01 ± 15.79 years old, 55.5% women). Response rate 36.3%. The mean systolic BP with three readings was 125.39 ± 17.43 mmHg, versus 124.33 ± 17.07 mmHg with the mean of the second and third readings (mean difference 1.01 ± 4.31; Cohen's D = 0.059). The mean diastolic BP was 73.93 ± 10.89 versus 73.71 ± 10.93 mmHg with both methods (mean difference 0.19 ± 2.11; Cohen's D = 0.017). Differences by age, sex, BMI, abdominal obesity, dyslipidemia, diabetes, smoking and sedentary lifestyle were all small (Cohen's D < 0.08). The agreement between both models for classifying subjects as hypertensive/non-hypertensive showed a Kappa value = 0.936 (McNemar's test p < 0.001). CONCLUSIONS: Determining the mean of three readings of BP does not make a significant difference in relation to the reading of the second and third measurements in a sample of general population.

[Control of blood pressure in Spanish hypertensive population attended in primary health-care. PRESCAP 2006 Study]. / Control de la presión arterial en la población hipertensa española atendida en atención primaria. Estudio PRESCAP 2006.

BACKGROUND AND OBJECTIVES: More information is needed on hypertension control and its evolution in clinical practice. This study aimed to determine the degree of blood pressure (BP) control in Spanish hypertensive patients attended in primary care (PC) and to determine the factors associated with poor BP control. PATIENTS AND METHOD: Cross-sectional, multicenter study, carried out in PC settings throughout Spain. Hypertensive patients >or= 18 years, with antihypertensive treatment (>or= 3 months) were consecutively recruited. BP measurement was performed in surgery hours (morning and evening) following standardized methods and averaging 2 consecutive readings. BP control was regarded as optimum when BP values were < 140/90 mmHg in general population and <130/80 mmHg in patients with diabetes, chronic renal disease or cardiovascular disease. RESULTS: 10,520 hypertensive patients were included (53.7% women), mean age (SD) 64.6 (11.3) years. 41.4% (95% confidence interval [CI], 40.5-42.4) presented good systolic BP (SBP) and diastolic BP (DBP) control, 46.5% (95% CI, 45.5-47.4) only SBP control and 67.1% (95% CI, 66.2-68.0) only DBP control. 55.6% of patients were treated with combination therapy (41.2% 2 drugs, 11.7% 3 and 2.8% more than 3). BP control was significantly (p<0.001) higher in the evening measurement (48.9%) than in the morning measurement (40.5%), and if patients had taken the treatment before measurement (42.0%) compared with those who had not taken it (38.8%). Factors such as diabetes, cardiovascular disease, sedentary lifestyle, alcohol consumption and surgery hour were associated with poor BP control (p<0.001). CONCLUSIONS: The results of the PRESCAP 2006 study indicate that 4 out of 10 hypertensive patients treated in PC in Spain have an optimal BP control. The degree of control of arterial hypertension has improved remarkably with respect to the PRESCAP 2002 study.

[Prevalence of undetected chronic kidney disease in dyslipidemic population treated in primary care. LIPICAP study]. / Prevalencia de la enfermedad renal crónica oculta en la población dislipémica asistida en atención primaria. Estudio LIPICAP.

BACKGROUND AND OBJECTIVE: Information about the prevalence of chronic kidney disease (CKD) in population treated in primary care (PC) is scarce. The aim of this study was to determine undetected CKD prevalence in dyslipidemic population measuring creatinine clearance according to the Cockcroft-Gault equation corrected for surface area. PATIENTS AND METHOD: Cross-sectional study including patients with diagnosis of dyslipidemia selected by consecutive sampling in PC. CKD was diagnosed when the glomerular filtration rate (GFR) was < 60 ml/min/1.73 m2. We assessed sociodemographic and clinical data, cardiovascular risk factors, coronary disease risk categories, dyslipidemia characteristics, functional CKD stage, and pharmacological treatments. RESULTS: The sample included 5,990 patients (50.2% women). The mean (standard deviation) age was 60.9 (11.1) years. The main reason for iclusion was hypercholesterolemia (65%), followed by mixed hyperlipidemia (26.4%), low high density lipoproteins (HDL)-cholesterol (4.9%) and hypertrigliceridemia (3.7%). According to the Cockcroft-Gault equation, CKD prevalence was 16.2% (95% confidence interval, 15.3-17.1) and it was significantly higher in women (22.7%) than in men (9.8%) (p < 0.0001). Patients with CKD were older compared with patients with normal GFR, and had higher systolic blood pressure, glucose and HDL-cholesterol (p < 0.001), as well as lower levels of total cholesterol, low density lipoproteins-cholesterol, and triglycerides (p < 0.01). The probability of presenting CKD was related to female gender, age, and lower body mass index. CONCLUSIONS: The LIPICAP study results indicate that almost 20% of PC dyslipidemic patients in Spain present undetected CKD when the GFR is measured according to the Cockcroft-Gault equation corrected for surface area.

[Arterial hypertension in immigrant patients in Spanish primary health care]. / Prevalencia de la hipertensión arterial en la población inmigrante asistida en atención primaria en España.

BACKGROUND AND OBJECTIVE: To evaluate the arterial hypertension (AHT) prevalence in a wide sample of immigrant patients. PATIENTS AND METHOD: A transversal and multicentric study that has included immigrant patients aged 18 years or more, consecutive sampling recruitment in primary healthcare consultations. The patient was defined with AHT hypertension when the average of 6 measurements in 3 visits (2 measurements per visit) was > or = 140 mmHg for the systolic blood pressure and/or 90 mmHg for diastolic blood pressure or if the patient had been previously diagnosed. RESULTS: 1,424 immigrants were followed-up (53.1% women) with average age (standard deviation) of 42.8 (13.1) years and mean stay in our country of 5.6 (5.7) years. Most of the patients' origin was Central and South America (40.2%) and Eastern Europe (21.9%). The prevalence of AHT was 31.4% (95% confidence interval [CI], 30.1-32.7%), of which the 62.1% where known patients. Patients coming from Asia showed a significant higher prevalence of AHT (40.0%; 95% CI, 38.7-41.3). CONCLUSIONS: Three of each 10 immigrant patients have AHT. There are significant differences according to the gender, the origin and period of residence of these patients.

Blood pressure differences between one automatic measurement and the mean value of 3 automatic measurements. SPRINT trial. / Diferencias de presión arterial entre una toma y la media de 3 tomas medidas automáticamente. Estudio SPRINT.

BACKGROUND AND OBJECTIVES: There are discrepancies regarding how to measure blood pressure (BP). The goal of this study was to determine the differences between one automatic BP measurement and the mean of 3 automatic BP measurements. PATIENTS AND METHOD: Two patient populations were used. A sample population (n=1,337) in which the measurement was performed by a nurse at the health center, and a consecutive series of patients (n=200) who had the measurement performed in front of the doctor in the office. RESULTS: The differences found between the first reading and the average of 3 determinations were small in both cases. In the population sample, BP levels ranged from 2.07 to 3.21mmHg, and in patients who had their BP levels measured in the presence of doctor, this value ranged from 2.71±3.82mmHg (systolic pressure), with minimal differences in diastolic BP levels. CONCLUSIONS: Little difference was found between the first determination and the average of 3 automatic BP readings.

[Baseline characteristics and clinical management of the first 3,000 patients enrolled in the IBERICAN study (Identification of the Spanish population at cardiovascular and renal risk)]. / Características basales y manejo clínico de los primeros 3.000 pacientes incluidos en el estudio IBERICAN (Identificación de la población española de riesgo cardiovascular y renal).

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.

[Control of hypertension in elderly patients receiving primary care in Spain]. / Control de la hipertensión arterial en la población española > or = 65 años asistida en atención primaria.

INTRODUCTION AND OBJECTIVES: Little information is available about the control of arterial hypertension in the elderly population. The aim of this study was to investigate hypertension control, factors associated with poor control, and general practitioners' responses to poor control in a large sample of hypertensive patients aged 65 years or older receiving primary care in Spain. PATIENTS AND METHOD: A cross-sectional study of elderly hypertensive patients taking antihypertensives was carried out. Blood pressure was measured in the standard manner. Blood pressure control was regarded as optimum if pressure averaged less than 140/90 mm Hg or, in diabetics, less than 130/85 mm Hg. RESULTS: The study included 5970 patients (mean age, 72.4 years; 62.8% women). Both systolic and diastolic blood pressures were well controlled in 33.5% of patients, systolic blood pressure alone in 35.5%, and diastolic blood pressure alone in 76.2%. Blood pressure control was found to be good more frequently when it was assessed in the evening (39.8%; P<.001), and when patients had taken treatment on the day of assessment (35.1%; P <.001). Some 12.9% of diabetics had pressures less than 130/85 mmHg and 9.7% had pressures less than 130/80 mmHg. General practitioners modified their therapeutic approach with only 17.2% of poorly controlled patients. CONCLUSIONS: Arterial blood pressure control was optimum in only three out of 10 Spanish hypertensive patients aged 65 years or older. Blood pressure control assessment was significantly influenced by surgery hours and by the timing of antihypertensive intake. General practitioners' therapeutic responses to poor control were too conservative.

Evolution of clinical profile, treatment and blood pressure control in treated hypertensive patients according to the sex from 2002 to 2010 in Spain.

OBJECTIVES: To examine the evolution of clinical profile, management of hypertension, and blood pressure (BP) control according to sex in the past decade in Spain. METHODS: Data were taken from three surveys (PRESión arterial en la población española en los Centros de Atención Primaria studies) aimed to determine BP control rates in treated hypertensive patients, who attended the primary care in Spain during 2002, 2006, and 2010, respectively. Adequate BP control was defined as BP lower than 140/90 mmHg for the general hypertensive population in the three surveys. In patients with diabetes, chronic kidney disease, or cardiovascular disease, BP control was established as lower than 130/85 mmHg in the 2002 survey and lower than 130/80 mmHg in the 2006 and 2010 surveys. RESULTS: A total of 12 754 (57.2% women), 10 520 (53.7% women), and 12 961 (51.7% women) patients were included. The proportion of patients with cardiovascular disease increased from 27.1% in men and 21.9% in women in 2002, to 33.0 and 23.9%, respectively, in 2010 (P < 0.0001 in men and women, respectively). In 2002, 36.3% of men and 35.9% of women achieved BP goals (P = NS); 39.7 and 42.9% in 2006 (P < 0.001); and 44.7 and 47.9% in 2010 (P < 0.0001). The proportion of men on combined therapy increased from 44.2% in 2002 to 63.9% in 2010 (P for trend < 0.0001), and in women it increased from 43.9 and 63.2%, respectively (P for trend <0.0001). CONCLUSION: Despite the fact that clinical profile of treated hypertensive patients has worsened in the past years in Spain, BP control rates have improved, particularly in women. This improvement was related with a higher use of combined therapy, regardless of sex.

Prevalence of Stable Angina in Spain. Results of the OFRECE Study.

INTRODUCTION AND OBJECTIVES: The objective of the OFRECE study was to estimate the prevalence of stable angina in Spain. This prevalence is currently unknown, due to a lack of recent studies and to changes in the epidemiology and treatment of ischemic heart disease. METHODS: This cross-sectional study involved a representative sample of the Spanish population aged 40 years or older, obtained via 2-stage random sampling: in the first stage, primary care physicians were randomly selected from each Spanish province, whereas in the second stage 20 people were selected from the population assigned to each physician. The prevalence was weighted by age, sex, and geographical area. Participants were classified as having angina if they met the "definite angina" criteria of the Rose questionnaire and as having confirmed angina if the angina was confirmed by a cardiologist or if they had a history of acute ischemic heart disease or revascularization. RESULTS: Of the 11 831 people invited to participate, 8378 (71%) were analyzed (mean age, 59.2 years). The weighted prevalence of definite angina (Rose) was 2.6% (95% confidence interval, 2.1%-3.1%) and was higher in women (2.9%) than in men (2.2%), whereas that of confirmed angina was 1.4% (95% confidence interval, 1.0%-1.8%), without differences between men (1.5%) and women (1.3%). The prevalence of definite angina (Rose) increased with age (0.7% in patients aged 40 to 49 years and 7.1% in those aged 70 years or older), history of cardiovascular disease, and cardiovascular risk factors, except smoking. CONCLUSIONS: The prevalence of definite angina (Rose) in the Spanish population aged 40 years or older was 2.6%, whereas that of confirmed angina was 1.4%. Both prevalences increased with age, cardiovascular risk factors, and cardiovascular history.

BACKGROUND AND OBJECTIVE: More information is needed on hypertension control in clinical practice, which includes taking at least two blood pressure (BP) readings and taking into account surgery times and previous antihypertensive drug intake. Our study aimed to assess the optimum degree of BP control in a broad sample of Spanish hypertensive patients in primary care and to determine factors associated with a poor control. PATIENTS AND METHOD: Cross-sectional, multicenter study of hypertensive patients aged over 18 years and treated with drugs during the preceeding three months, who were recruited by general practitioners through consecutive sampling in primary care settings throughout Spain over 3 consecutive days. BP measurements were performed in surgery hours (morning and evening) following standardized methods and averaging two consecutive readings. An average BP lower than 140/90 mm Hg (values lower than 130/85 mm Hg in diabetics) was regarded as optimum BP control. RESULTS: 12 754 patients were included, mean age 63.3 years (10.8), 57.2% women. 36.1% (95% CI, 35.2-36.9) had good systolic blood pressure (SBP) and diastolic blood pressure (DBP) controls, 39.1% (95% CI, 38.3-40.0) had good SBP control only, and 73.1% (95% CI, 72.3-73.9) had good DBP control only. BP control was significantly (*2, p < 0.001) better during evening than during morning measurements (43.6% vs 37.1%) and in patients who had taken antihypertensive treatment before measurement (37.2%) vs. those who had not taken it (21.0%). Factors such as alcohol consumption, sedentary lifestyle, obesity and age were all associated with poor BP control (Wald's (chi 2, p < 0.001). CONCLUSIONS: The results of the PRESCAP 2002 study indicate that approximately 4 out of 10 hypertensive patients treated pharmacologically by primary health care centers in Spain have optimal BP control. Significant differences were found in the degree of control depending on surgery hours and the previous intake of antihypertensive medication.

Blood pressure control and management of very elderly patients with hypertension in primary care settings in Spain.

This study aimed to determine the clinical profile, blood pressure (BP) control rates, therapeutic management and physicians' therapeutic behavior regarding very elderly hypertensive patients. A total of 1540 hypertensive patients 80 years old on antihypertensive therapy and receiving care in primary care settings in Spain were included in this cross-sectional study. The mean patient age was 83.4±3.1 years, 61.9% of patients were women and 49.3% of patients had cardiovascular disease. Of the patients, 27.7% were on monotherapy and 72.3% were on combined therapy (47.4% on two antihypertensive agents and 24.9% on three or more antihypertensive agents). A total of 40.8% (95% confidence interval (CI): 38.4-43.3%) of patients achieved BP goals (<140/90 mm Hg; <130/80 in patients with diabetes, chronic renal disease or cardiovascular disease). Patients with uncontrolled BP were more likely to have metabolic syndrome, diabetes, obesity, a history of cardiovascular disease, ischemic heart disease, renal disease and stroke and were more frequently smokers. Physicians modified the antihypertensive regimens for 27.4% (95% CI: 23.9-30.8%) of the patients with uncontrolled BP, and the addition of another antihypertensive agent was the most frequent modification. With regard to the physicians' perception of patients' BP control, the BPs of 44.1% of the patients with uncontrolled BP were considered well controlled by the physicians.

Prevalence of atrial fibrillation in Spain. OFRECE study results.

INTRODUCTION AND OBJECTIVES: Atrial fibrillation is associated with substantial morbidity and mortality and both its incidence and prevalence are high. Nevertheless, comprehensive data on this condition in Spain are lacking. The aim of this study was to estimate the prevalence of atrial fibrillation in Spain. METHODS: A cross-sectional study was conducted in the general Spanish population older than 40 years. Two-stage random sampling was used, in which first-stage units were primary care physicians randomly selected in every Spanish province and second-stage units were 20 randomly selected persons drawn from each participating physician's assigned population. The reported prevalence was standardized for the age and sex distribution of the Spanish population. The electrocardiogram recordings were read centrally. RESULTS: Overall, 8343 individuals were evaluated. The mean age was 59.2 years (95% confidence interval, 58.6-59.8 years), and 52.4% of the participants were female. The overall age-adjusted prevalence of atrial fibrillation was 4.4% (95% confidence interval, 3.8-5.1). Prevalence was similar in both sexes, men 4.4% (3.6-5.2) and women 4.5% (3.6-5.3), rising with increasing age older than 60 years. In patients older than 80 years, the prevalence was 17.7% (14.1-21.3). In 10% of patients an unknown atrial fibrillation was diagnosed. CONCLUSIONS: The prevalence of atrial fibrillation in the general Spanish population older than 40 years is high, at 4.4%. The prevalence is similar in both sexes and rises steeply above 60 years of age. It is estimated that there are over 1 million patients with atrial fibrillation in the Spanish population, of whom over 90,000 are undiagnosed.

Perspectiva de género en el estudio OFRECE: diferencias en la atención entre pacientes que consultan por dolor torácico o por palpitaciones / The gender perspective within the OFRECE study: differences in health care among patients consulting for chest pain and/or palpitations

Introducción y objetivos: En un estudio de base poblacional, se analizaron las posibles diferencias en función del sexo en la atención al dolor torácico o las palpitaciones como motivo de consulta. Métodos: El estudio OFRECE incluyó una muestra aleatoria de la población española de 8.400 participantes de edad ≥ 40 años, de los que 1.132 (13,5%) tenían antecedentes de consulta por dolor en el pecho y 1.267 (15,1%), por palpitaciones y se incluyen en este estudio. Se calculó la odds ratio (OR) de que se practicaran determinadas pruebas y se comunicaran los resultados de las consultas en relación con el hecho de ser mujer, tanto brutas como ajustadas por los factores de riesgo cardiovascular clásicos, antecedentes de enfermedad cardiovascular y diagnóstico de angina estable o fibrilación auricular confirmado en este estudio en cada caso. Resultados: No se observaron diferencias en los antecedentes de consulta por dolor torácico entre mujeres y varones (el 13 y el 14,1%; p=0,159) y sí en las consultas por palpitaciones (el 19,0 y el 10,4% respectivamente; p <0,001). A las mujeres con antecedentes de consulta por dolor torácico, en comparación con los varones, se les realizaron menos ecocardiogramas (el 32,5 y el 45,3%; p <0,001), se las remitió con menor frecuencia al cardiólogo (el 49,1 y el 60,1%; p <0,001), ingresaron menos (el 20,1 y el 39,4%; p <0,001) y se alcanzó un diagnóstico en menor proporción de casos (el 60,9 y el 71,9%; p <0,001). Al ajustar, disminuyen las diferencias y dejan de ser significativas en todos los casos: para ecocardiogramas, OR ajustada=0,81 (IC95%, 0,60-1,09); para remisión al cardiólogo, OR ajustada=0,86 (IC95%, 0,63-1,16), y para ingreso, OR ajustada=0,76 (IC95%, 0,54-1,09). En el caso de las palpitaciones, las diferencias no ajustadas son menores y todas desaparecen al ajustar. Conclusiones: Este trabajo no confirma un sesgo en razón del sexo en la atención a estos síntomas, aunque no es descartable completamente un sesgo de género en el diagnóstico confirmado en el estudio que limite su capacidad para identificar diferencias en la atención a las pacientes

Introduction and objectives: To analyze differences between sexes in the clinical management of patients presenting with symptoms of chest pain and/or palpitations within a population-based study. Methods: The OFRECE study included a random sample of 8400 individuals from the Spanish population aged 40 years and older; 1132 (13.5%) had previously consulted for chest pain and 1267 (15.1%) had consulted for palpitations and were included in the present study. We calculated both the crude and adjusted odds ratios (OR) of undergoing certain tests and the results of consultations by sex. Adjustment was performed by classic cardiovascular risk factors, a personal history of cardiovascular disease, and a diagnosis of stable angina or atrial fibrillation confirmed in the OFRECE study in each case. Results: No differences were observed in history of consultation for chest pain between women and men (13% vs 14.1%; P=.159) but differences were found in palpitations (19% vs 10.4%, respectively; P <.001). Women who had previously consulted for chest pain underwent fewer echocardiograms (32.5% vs 45.3%, respectively; P <.001), were less frequently referred to a cardiologist (49.1% vs 60.1%; P <.001), were less often admitted to hospital (20.1% vs 39.4%; P <.001), and less frequently received a confirmed diagnosis (60.9 vs 71, 9; P <.001). After full adjustment, all differences decreased and become nonsignificant echocardiograms: adjusted OR, 0.81; 95%CI, 0.60-1.09; referral to a cardiologist: adjusted OR, 0.86; 95%CI, 0.63-1.16; hospital admission: adjusted OR, 0.76; 95%CI, 0.54-1.09). For palpitations, crude differences were smaller and all became nonsignificant after adjustment. Conclusions: This study does not confirm the existence of sex-related bias in the management of chest pain and palpitations. However, such bias cannot be completely ruled out in diagnoses confirmed within the OFRECE study, which might limit its ability to detect sex-related differences in health care
