ABSTRACT: Our aim was to assess the ambulatory blood pressure monitoring (ABPM) characteristics or patterns in hypertensive patients with diabetes compared with non-diabetic hypertensives. We performed a cross-sectional analysis of a 68,045 patient database from the Spanish Society of Hypertension ABPM Registry, a nation-wide network of >1200 primary-care physicians performing ABPM under standardized conditions in daily practice. We identified 12,600 (18.5%) hypertensive patients with diabetes. When compared with patients without diabetes, diabetic hypertensives exhibited higher systolic blood pressure (BP) levels in every ABPM period (daytime 135.4 vs. 131.8, and nighttime 126.0 vs. 121.0 mm Hg, P<0.001 for both) despite they were receiving more antihypertensive drugs (mean number 1.71 vs. 1.23, P<0.001). Consequently, diabetic patients suffered from lack of control of BP more frequently than non-diabetic subjects particularly during the night (65.5% vs. 57.4%, P<0.001). Prevalence of a non-dipping BP profile (64.2% vs. 51.6%, P<0.001) was higher in diabetic patients. In the other hand, prevalence of 'white-coat' hypertension in diabetic patients was 33.0%. We conclude that there was a remarkably high prevalence of alterations in ABPM in patients with diabetes. Abnormalities in systolic BP, particularly during the night, and in circadian BP pattern could be linked with the excess of BP-related cardiovascular risk of diabetes. A wider use of ABPM in diabetic patients should be considered.

ABSTRACT: The available information regarding blood pressure control in women is scarce. This study was aimed at assessing blood pressure control and predictors of a lack of blood pressure control in the primary care setting in a large sample of hypertensive women.
Women aged 65 years or older with an established diagnosis of hypertension (≥ 6 months of evolution) were included in a cross-sectional, multicenter study. Blood pressure readings were taken following the current guidelines, and the value for each visit was the average of two separate measurements. Adequate blood pressure control was defined as < 140/90 mm Hg (< 130/80 mm Hg for diabetics).
A total of 4274 hypertensive women (mean age: 73.6 years [6.1 years]) were included in the study; blood pressure was controlled in 29.8% (95% confidence interval: 28.4%-31.1%) of the study population. Combined therapy was administered in 67.6% of patients (46.3% with 2 drugs and 21.7% with 3 or more drugs). The most common organ damage was left ventricular hypertrophy (33.8%) and the most common associated condition was heart failure (19%). Poor blood pressure control was more frequent in patients with more cardiovascular risk factors, organ damage, and associated clinical conditions (P<.01). A more recent hypertension diagnosis, LDL-cholesterol > 115 mg/dl, monotherapy, obesity, and hemoglobin A(1c) ≥ 7% were associated with a lack of blood pressure control (P < .0001).
Only 3 in 10 hypertensive women aged ≥ 65 years monitored daily in the primary care setting achieved their blood pressure goals. A recent diagnosis of hypertension was the main predictor of poor blood pressure control.

ABSTRACT: Hypertension is highly prevalent in the very elderly. We studied control rates of hypertension according to clinic blood pressure (BP) and ambulatory BP monitoring (ABPM) in treated hypertensives aged > or =80 years.
Data came from the Spanish Society of Hypertension ABPM Registry (CARDIORISC - MAPAPRES project), which comprises a nation-wide network of more than 1,000 physicians sending standardized ABPM registries via web. Between June 2004 and April 2007 we obtained a 33.829-patient database. Control of hypertension was defined at the clinic when office BP was <140/90mmHg and at the ABPM when mean BP during the 24-h period was <130/80mmHg.
We identified 2,311 patients (6.8%) aged > or =80 years. Mean age (SD) was 83.1 (3.2) years and 63% were women. Control of clinic BP was observed in 21.5% of cases (95%CI: 19.1-23.9) and control of 24-h BP in ABPM was 42.1% (95%CI: 39.7-45.3). Prevalence of masked hypertension was 7.0% (95%CI: 6.0-8.0) and prevalence of office-resistant control (white coat) was 27.6% (95% CI: 25.7-29.4). Diabetes, kidney disease, and duration of hypertension were associated with lack of control in ABPM.
In very old hypertensives, control of clinic BP was 21.5% but ambulatory-based hypertension control was 42.1%. Physicians should be aware that the likelihood of misestimating BP control is high in these subjects. A wider use of ABPM in the elderly with hypertension should be considered.

ABSTRACT: This study sought to assess blood pressure (BP) control rates by determining the factors associated with poor BP control, therapeutic management and physicians' therapeutic behavior among elderly Spanish hypertensive patients in a primary care setting. This cross-sectional multicenter study included hypertensive patients at least 80 years of age in primary care settings throughout Spain who were on pharmacologic treatment. BP was considered well controlled at <140/90 mm Hg (<130/80 in patients with diabetes, chronic renal disease or cardiovascular disease). A total of 923 patients were included (83.3+/-3.5 years; 62.9% women). Almost two-thirds (64.0%) of the patients were taking a combined therapy (68.7%; 2 drugs) and approximately one-third (35.6%; 95% CI 32.6-38.7) of the patients attained BP goals. Physicians modified the antihypertensive treatment in 26.1% (95% CI 22.3-29.9) of patients with uncontrolled BP, which most frequently involved the addition of another drug (47.6%). Predictive factors for no BP control and no therapeutic modification in patients with uncontrolled BP included diabetes (OR 2.8 (95% CI 2.0-3.9); P<0.0001) and mistaken physician perceptions about BP control (OR 108.1 (95% CI 40.5-288.6); P<0.0001), respectively. Only three out of 10 hypertensive patients 80 years or older in Spain achieved the BP goals. Physicians only modified the treatment in one out of four patients with uncontrolled BP. Diabetes was associated with a threefold increase in the likelihood of uncontrolled BP, and the mistaken physician perceptions about BP control were associated with a 100-fold rise in the probability of not modifying antihypertensive therapy.

ABSTRACT: Ambulatory blood pressure (BP) monitoring has become useful in the diagnosis and management of hypertensive individuals. In addition to 24-hour values, the circadian variation of BP adds prognostic significance in predicting cardiovascular outcome. However, the magnitude of circadian BP patterns in large studies has hardly been noticed. Our aims were to determine the prevalence of circadian BP patterns and to assess clinical conditions associated with the nondipping status in groups of both treated and untreated hypertensive subjects, studied separately. Clinical data and 24-hour ambulatory BP monitoring were obtained from 42,947 hypertensive patients included in the Spanish Society of Hypertension Ambulatory Blood Pressure Monitoring Registry. They were 8384 previously untreated and 34,563 treated hypertensives. Twenty-four-hour ambulatory BP monitoring was performed with an oscillometric device (SpaceLabs 90207). A nondipping pattern was defined when nocturnal systolic BP dip was <10% of daytime systolic BP. The prevalence of nondipping was 41% in the untreated group and 53% in treated patients. In both groups, advanced age, obesity, diabetes mellitus, and overt cardiovascular or renal disease were associated with a blunted nocturnal BP decline (P<0.001). In treated patients, nondipping was associated with the use of a higher number of antihypertensive drugs but not with the time of the day at which antihypertensive drugs were administered. In conclusion, a blunted nocturnal BP dip (the nondipping pattern) is common in hypertensive patients. A clinical pattern of high cardiovascular risk is associated with nondipping, suggesting that the blunted nocturnal BP dip may be merely a marker of high cardiovascular risk.

ABSTRACT: Studies on the impact of weight excess and fat distribution on blood pressure are usually limited to young and middle-aged population, and data on the elderly are scarce.
We performed an analysis of the Prevencion de Riesgo de Ictus, a population-based study on individuals aged 60 years or more in Spain, to assess the impact of weight excess, stratified by body mass index (normal <25; overweight 25-29.9; obesity > or =30 kg/m), and waist circumference [increased if > or =88 cm (women) or > or =102 (men)] on the prevalence on hypertension and lack of blood pressure control. In 6263 individuals (mean age 71.9 years old, 53.3% women; 73.0% with diagnosed hypertension), prevalence of obesity was 35.0%, and 65.6% showed an increased waist circumference. Body mass index and waist circumference showed an independent impact on the prevalence and absence of hypertension control. In a multivariate model including age, sex, body mass index, and waist circumference, prevalence of hypertension was higher in the overweight and obesity groups (odds ratio 1.41 and 1.96, respectively, compared to normal weight), and in those with increased waist circumference (odds ratio 1.25) compared with normal waist circumference. After further adjustment for antihypertensive therapy, overweight, and obesity (odds ratio 1.40 and 1.59, respectively) as well as increased waist circumference (odds ratio 1.39) were independently related to absence of blood pressure control. The impact of waist circumference on hypertension and blood pressure control was shown in each category of body mass index.
In this cross-sectional study in an elderly population, body mass index and waist circumference showed an independent and direct impact on the prevalence of hypertension and on the absence of blood pressure control.

ABSTRACT: Data on the prevalence of obesity in elderly population in Spain are scarce. The objective of this work was to describe the prevalence of obesity and the related factors in a random sample of Spanish population aged 60 years-old or more, stratified by autonomous communities.
We analyzed the PREV-ICTUS study, a population-based study carried out between September and December 2005 in a random sample stratified by autonomous communities according to the census of inhabitants and the habitat in each community. Subjects were classified as with normal weight (body mass index [BMI] < 25 kg), overweight (BMI 25-29.9) and obesity (BMI > or = 30 kg).
In 6,843 subjects -mean age (standard deviation): 71.9 (7.1) years-old; 53.3% women-, prevalence of obesity was 34.5% (95% confidence interval [CI], 33.3-35.5%), higher in women (38.4%; 95% CI, 36.8-39.9%) than in men (30.0%; 95% CI, 28.4-31.6%; p < 0.001), with a tendency to decrease in the older population. In total, 81.7% of the population showed overweight (BMI > or = 25). Prevalence differed among communities from 46.4% to 20.7% (p < 0.001). In the multivariate analysis, obesity was inversely related to age (odds ratio [OR] = 0.98 per each year increment), and directly to female gender (OR = 1.25), rural (OR = 1.50) or semi-urban habitat (OR = 1.38), sedentary lifestyle (OR = 1.86) and non-smoking history (OR = 1.19).
Obesity was present in one out of 3 individuals of this reasonably representative sample of the Spanish population in an age range, 60 years-old or more, which concentrates a high cardiovascular risk. Differences in the prevalence among autonomus communities were detected.

ABSTRACT: To assess the relationship between different serum lipid profiles and the prevalence of established cardiovascular disease (CVD) in an elderly population.
An analysis was undertaken of the PREV-ICTUS population-based study on Spanish subjects aged > or =60 years. The following definitions were used: abnormal LDL cholesterol (LDL-C): > or =130 mg/dl (> or =3.3 mmol/L), or > or =100 mg/dl (> or =2.5 mmol/L) in those with diabetes or CVD, or treatment with any hypolipidaemic drug; low HDL cholesterol (HDL-C): <40 mg/dl (<1 mmol/L) (men), or <50 mg/dl (<1.3 mmol/L) (women), and abnormal triglycerides (TG): > or =150 mg/dl (> or =1.7 mmol/L) or treatment with fibrates. We defined eight groups: A (normal lipid profile), B (isolated abnormal LDL-C), C (isolated abnormal TG), D (isolated low HDL-C), E (abnormal LDL-C and HDL-C), F (abnormal LDL-C and TG), G (abnormal TG and HDL-C), H (abnormal LDL-C, HDL-C and TG). A multivariate analysis was performed to assess the relationship between each lipid profile and CVD.
A total of 6010 subjects (mean age 71.7 years, 53.5% women, 73.2% with hypertension, 29.2% with diabetes mellitus, 24.3% with CVD), were included in the analysis. LDL-C elevation was present in 78.1%, 23.3% had low HDL-C and 35.7% abnormal TG. Combined dyslipidaemias were frequent (40.3%). Odds ratios (95% confidence intervals) for CVD, compared with those with a normal lipid profile, were 2.07 (1.24-3.46) for abnormal HDL-C (p = 0.005), 4.09 (3.10-5.39) for abnormal LDL-C; 6.41 (4.59-8.95) for abnormal LDL-C plus HDL-C, 5.33 (3.98-7.14) for abnormal LDL-C plus TG and 7.59 (5.51-10.5) for those with the three parameters altered (all p < 0.001). Compared with those with isolated LDL-C elevation, those with abnormal LDL-C plus HDL-C had 1.57 (1.30-1.97) higher odds of having CVD (p < 0.001), the figures being 1.30 (1.11-1.53) for those with abnormal LDL-C plus TG and 1.86 (1.52-2.28) for those with abnormal LDL-C, TG plus HDL-C (p < 0.001).
Lipid abnormalities are frequent in the elderly, and are associated with the presence of CVD. Low HDL-C and/or abnormal TG levels, when added to abnormal LDL-C, are associated with a higher prevalence of CVD, suggesting the advisability of a comprehensive lipid evaluation and treatment earlier in life.

ABSTRACT: To assess the prevalence of low glomerular filtration rate (GFR < 60 ml/min/1.73 m2) in general population of subjects aged 60 years or older of Spain, and the related factors.
Analysis of PREV-ICTUS, a population-based study carried out in a sample of subjects aged 60 years or more, randomly selected and stratified by Autonomic Communities according to the census of inhabitants and the habitat in each Community. Demographic data, cardiovascular risk factors and diseases were collected. GFR was calculated using the MDRD (Modification of Diet in Renal Disease) equation.
In 6,799 subjects (age 71.9 years-old; 53.6% women; 72.9% with arterial hypertension [HT]; 27.0% with diabetes mellitus [DM]; 24.3% with cardiovascular disease), 25.9% had low GFR (95% confidence interval, 24.8-26.9). The prevalence increased linearly, from 16.5% in subjects aged 60-64 years to 46.5% in those aged 85 or more (p < 0.001), and was higher in women (36.1% vs 14.1% in men, p < 0.001). In the multivariate analysis, low GFR was independently related to advanced age (odds ratio [OR] between 1.30 y 4.20), female gender (OR = 5.82), HT older than 7 years (OR = 1.23), uric acid (OR = 1.52 for each increment of 1 mg/dl) and cardiovascular disease (OR = 1.68). The association with DM did not reach statistical significance. In a model without cardiovascular disease, related factors remained the same, increasing the significance of HT older than 7 years (OR = 1.31) and of DM (OR = 1.19).
One out or 4 subjects of this sample showed low GFR. The variables directly associated with low GFR were advanced age, female gender, HT of longer evolution, cardiovascular disease, increased uric acid, and, in one model, DM.

ABSTRACT: Despite the well-known significant relationship between blood pressure and cardiovascular mortality, few data are available on the blood pressure characteristics of dyslipidemic patients. The aims of this study were to determine the blood pressure characteristics of dyslipidemic patients being treated in primary care, and to identify factors associated with poor blood pressure control.
This multicentre cross-sectional study involved patients of both sexes aged > or =18 years who were diagnosed with dyslipidemia (i.e., hypercholesterolemia, hypertriglyceridemia, mixed dyslipidemia, or a low high-density lipoprotein cholesterol level) in the 17 Spanish autonomous regions. Blood pressure was measured according to standard procedures, and was considered well-controlled if it was <140/90 mm Hg (or <130/80 mm Hg in patients with diabetes, nephropathy or cardiovascular disease).
In total, 7054 patients were studied (mean age 61.3 [11.2] years, 50.8% male). Mean systolic and diastolic blood pressures were 134.6 [14.2]/79.8 [8.9] mm Hg, with significant differences (P< .001) between hypertensives (140.8 [14.6]/82.8 [9.0] mmHg) and normotensives (128.5 [10.7]/76.9 [7.7] mm Hg). Good blood pressure control was observed in 47.4% (95% confidence interval, 46.3-48.5%) of subjects overall, in 29.3% of hypertensives, and in 12.8% of hypertensive diabetics. Poor control was associated with an increased cardiovascular disease risk (hazard ratio [HR]=2.89), poor control of low-density lipoprotein cholesterol (HR=1.43), a higher body mass index (HR=1.06), and older age (HR=1.02).
Fewer than half of dyslipidemic primary-care patients in Spain had good blood pressure control. Poor control was associated, in particular, with increased cardiovascular risk and poor control of the low-density lipoprotein cholesterol level.

ABSTRACT: The aims of this study were to determine the prevalence of atrial fibrillation in individuals aged 60 years or more in Spain using a random sample of the population and to identify associated factors.
An analysis of the PREV-ICTUS study, a randomized cross-sectional population-based study of individuals aged 60 years or more, was carried out. Data on demographic variables, cardiovascular risk factors, and cardiovascular disease were obtained from medical records. The diagnosis of atrial fibrillation was based on the patient's medical history and an electrocardiogram performed during the study.
In the 7108 individuals studied (mean age 71.9 [7.1] years, 53.6% female), the prevalence of atrial fibrillation was 8.5% (95% confidence interval [CI] 7.9-9.2%). It was higher in males (9.3% vs 7.9% in females; P=.036) and increased from 4.2% in individuals aged 60-64 years to 16.5% in those aged 85 years or more (chi-squared test for linear trend, P< .001). Multivariate analysis showed that existing cardiovascular disease, hypertension, age, and left ventricular hypertrophy had the strongest associations with atrial fibrillation. Although there was a strong relationship between hypertension and atrial fibrillation (odds ratio 2.53, 95% CI, 1.60-4.01), no association was found between poor blood pressure control and atrial fibrillation. A weak association with diabetes mellitus was found only when arterial pressure was included in the model, but not when a diagnosis of hypertension was included.
In this cross-sectional population-based study of elderly individuals, the prevalence of atrial fibrillation was 8.5%, and was strongly associated with existing cardiovascular disease, hypertension, age and left ventricular hypertrophy.

ABSTRACT: Although blood pressure (BP) control is crucial in hypertensive patients, clinical practice guidelines agree that the goal of treatment should be aimed at not only decreasing BP but reducing global cardiovascular risk. The aim of this cross-sectional study was to evaluate BP, low-density lipoprotein cholesterol (LDL-C), and composite control rates in a hypertensive population in a primary care setting in Spain. Good BP control was defined as <140/90 mm Hg (<130/80 mm Hg for diabetics).LDL-C control rate was established according to the third report of the National Cholesterol Education Program Adult Treatment Panel criteria. A total of 12,954 patients (49.9% women, aged 62.1+/-10.7 years) were included. BP was controlled in 24.8% of patients, LDL-C in 26% of patients and, when combined, in only 8.6%. The rates of control were significantly worse in high-risk subgroups, such as high-coronary-risk, diabetic, or metabolic syndrome patients. The BP and LDL-C control rates in the hypertensive population attended to daily in primary care settings in Spain are low.

ABSTRACT: The objective of this study was to estimate the high blood pressure values and the 10-year risk of stroke in the Spanish general population aged 60 years or older using the Framingham scale.
This was a multicenter, population-based, cross-sectional study performed in Spanish primary care centers. A randomized selection of centers and recruitment population was used. We collected clinical, biochemical, and electrocardiographic data.
We analyzed 7343 subjects (mean age, 71.6 years; standard deviation, 7.0; 53.4% females, 34.4% obese subjects, and 27.1% diabetic subjects). Electrocardiographic-left ventricle hypertrophy was present in 12.9% of the subjects, atrial fibrillation in 8.4%, and established cardiovascular disease in 28.9%; 73.0% already had hypertension diagnosed, and 12.8% showed high blood pressure without a prior diagnosis of hypertension. Among hypertensive subjects, 29.1% had high blood pressure on therapeutic objective, and of the total population 35.7% had high blood pressure under control. Those with hypertension already diagnosed showed a higher prevalence of other stroke risk factors (left ventricle hypertrophy, atrial fibrillation, diabetes, or established cardiovascular disease). The estimated 10-year stroke risk was 19.6% (standard deviation, 17.3%), and was greater in hypertensive patients (23.7%; standard deviation, 18.5) than in patients with high blood pressure without known hypertension (12.4%; standard deviation, 9.2), or in normotensive subjects (5.3%; standard deviation, 0.2; P<0.001).
The 10-year estimated stroke risk was 19.6%, and it was greater in hypertensive patients as compared with the remainder people at any blood pressure range. The concomitant stroke risk factors are more prevalent in patients with hypertension already diagnosed, which implies an important additional estimated risk of stroke.

ABSTRACT: The objective was to assess the stroke risk and prevalence of the cardiovascular risk factors and to analyze their relationship with the specific stroke rates of mortality in each of the autonomic communities of Spain. We conducted a multicenter, cross-sectional study of population >60 years old in Spanish primary care centers. In all of the subjects, clinical, biochemical, and electrocardiographic data were obtained, and the 10-year stroke risk was calculated using the Framingham score. Mortality rates of stroke, age and sex adjusted, were obtained for each of the autonomic communities from the Ministry of Health. A total of 7343 subjects (mean age: 71.6 years, 53.4% women, 34.4% obese, and 27.1% diabetic subjects) were analyzed. A total of 73% were already diagnosed with hypertension. Among hypertensive subjects, 29.1% had blood pressure on therapeutic objective, and, of the total population, 35.7% had blood pressure under control. ECG-left ventricular hypertrophy was present in 12.9% of the subjects. The estimated stroke risk was 19.6%. Stroke mortality rates were significantly related to the estimated 10-year stroke risk (r=0.41; P<0.05) in each autonomic community. Poor hypertension control (P=-0.42; P<0.05) and prevalence of ECG-left ventricular hypertrophy (P=0.52; P<0.05) were the main factors related to the stroke mortality rates after controlling by age, sex, obesity, diabetes, and urban setting. Differences in stroke mortality throughout the autonomic communities of Spain were associated with indexes of worse blood pressure handling, low control rates, and high left-ventricular hypertrophy.

ABSTRACT: This study was designed to evaluate whether primary care physicians in Spain accurately diagnose the metabolic syndrome in hypertensive patients, to define the profile and management of these patients in clinical practice, and to ascertain the level of blood pressure and low-density lipoprotein cholesterol control. Data were analyzed from a cross-sectional survey involving 12,954 patients with hypertension (Prevención Cardiovascular en España en Atención Primaria: Intervención Sobre el Colesterol en Hipertensión [PRESCOT] study), wherein 52% of the cohort fulfilled the National Cholesterol Education Program-Adult Treatment Panel criteria for the metabolic syndrome. The majority of patients (54.6%) had 3 risk factors, 32.4% had 4, and 13% had 5 risk factors. Physician diagnosis of the metabolic syndrome was poor, with 43.7% of physicians missing the diagnosis and 12.9% wrongly diagnosing the metabolic syndrome. Blood pressure and low-density lipoprotein cholesterol control rates were very low, with only 4.7% of metabolic syndrome patients achieving control for both blood pressure and low-density lipoprotein cholesterol vs 13.5% for non-metabolic syndrome patients (P<.0001). These findings demonstrate that the metabolic syndrome is common in patients with hypertension and that it is generally poorly diagnosed and treated by primary care physicians.

ABSTRACT: Introducción y objetivosEl objetivo de este estudio fue analizar la prevalencia de fibrilación auricular (FA) en sujetos ≥ 60 años en España y los factores asociados, en una muestra aleatoria de base poblacional.MétodosAnálisis del estudio PREV-ICTUS, estudio transversal de base poblacional en sujetos ≥ 60 años. Se recogieron datos demográficos, factores de riesgo y enfermedades cardiovasculares. La FA fue diagnosticada por la historia médica y un electrocardiograma realizado en el momento del estudio.ResultadosEn 7.108 sujetos (edad media 71,9 ± 7,1 años, el 53,6%, mujer), la prevalencia de FA fue del 8,5% (intervalo de confianza [IC] del 95%, 7,9-9,2), mayor en varones (del 9,3%, frente al 7,9% en mujeres; p = 0,036) y aumentó desde el 4,2% en sujetos de 60-64 años al 16,5% en los ≥ 85 años (χ2 de la tendencia lineal; p < 0,001). En los modelos multivariables, la enfermedad cardiovascular establecida, la hipertensión, la edad y la hipertrofia ventricular izquierda tuvieron la asociación más fuerte con la FA, mientras que la hipertensión se relacionó con fuerza con la FA (oddsratio [OR] = 2,53; IC del 95%, 1,60-4,01) y no encontramos asociación entre peor control de la presión arterial y FA. La diabetes mellitus únicamente se asoció débilmente cuando en el modelo se introdujeron los valores de presión arterial y no el diagnóstico de hipertensión.ConclusionesEn este estudio poblacional en sujetos de edad avanzada, la prevalencia de FA fue del 8,5% y se asoció con fuerza con la presencia de enfermedad cardiovascular, la hipertensión, la edad y la hipertrofia ventricular izquierda.Introduction and objectivesThe aims of this study were to determine the prevalence of atrial fibrillation in individuals aged 60 years or more in Spain using a random sample of the population and to identify associated factors.MethodsAn analysis of the PREV-ICTUS study, a randomized cross-sectional population-based study of individuals aged 60 years or more, was carried out. Data on demographic variables, cardiovascular risk factors, and cardiovascular disease were obtained from medical records. The diagnosis of atrial fibrillation was based on the patient's medical history and an electrocardiogram performed during the study.ResultsIn the 7108 individuals studied (mean age 71.9 [7.1] years, 53.6% female), the prevalence of atrial fibrillation was 8.5% (95% confidence interval [CI] 7.9–9.2%). It was higher in males (9.3% vs 7.9% in females; P=.036) and increased from 4.2% in individuals aged 60–64 years to 16.5% in those aged 85 years or more (chi-squared test for linear trend, P<.001). Multivariate analysis showed that existing cardiovascular disease, hypertension, age, and left ventricular hypertrophy had the strongest associations with atrial fibrillation. Although there was a strong relationship between hypertension and atrial fibrillation (odds ratio 2.53, 95% CI, 1.60–4.01), no association was found between poor blood pressure control and atrial fibrillation. A weak association with diabetes mellitus was found only when arterial pressure was included in the model, but not when a diagnosis of hypertension was included.ConclusionsIn this cross-sectional population-based study of elderly individuals, the prevalence of atrial fibrillation was 8.5%, and was strongly associated withexisting cardiovascular disease, hypertension, age and left ventricular hypertrophy.
