Clinical Features of 8295 Patients With Resistant Hypertension Classified on the Basis of Ambulatory Blood Pressure Monitoring

We aimed to estimate the prevalence of resistant hypertension through both office and ambulatory blood pressure monitoring in a large cohort of treated hypertensive patients from the Spanish Ambulatory Blood Pressure Monitoring Registry. In addition, we also compared clinical features of patients with true or white-coat–resistant hypertension. In December 2009, we identified 68 045 treated patients with complete information for this analysis. Among them, 8295 (12.2% of the database) had resistant hypertension (office blood pressure ≥140 and/or 90 mm Hg while being treated with ≥3 antihypertensive drugs, 1 of them being a diuretic). After ambulatory blood pressure monitoring, 62.5% of patients were classified as true resistant hypertensives, the remaining 37.5% having white-coat resistance. The former group was younger, more frequently men, with a longer duration of hypertension and a worse cardiovascular risk profile. The group included larger proportions of smokers, diabetics, target organ damage (including left ventricular hypertrophy, impaired renal function, and microalbuminuria), and documented cardiovascular disease. Moreover, true resistant hypertensives exhibited in a greater proportion a riser pattern (22% versus 18%; P<0.001). In conclusion, this study first reports the prevalence of resistant hypertension in a large cohort of patients in usual daily practice. Resistant hypertension is present in 12% of the treated hypertensive population, but among them more than one third have normal ambulatory blood pressure. A worse risk profile is associated with true resistant hypertension, but this association is weak, thus making it necessary to assess ambulatory blood pressure monitoring for a correct diagnosis and management.

Clinical differences between resistant hypertensives and patients treated and controlled with three or less drugs.

Background and aim: Clinical characteristics of resistant hypertensive patients in comparison to controlled patients have not been fully investigated in large cohorts. The aim of the study was to evaluate clinical differences, target organ damage and ambulatory blood pressure monitoring in resistant hypertensive patients and patients controlled on three or less drugs. Methods: In December 2010, from the Spanish Ambulatory Blood Pressure Monitoring Registry, we identified 14 461 patients fulfilling criteria of resistant hypertension and 13 436 hypertensive patients controlled on three or less drugs. Clinical characteristics were compared between these two groups. Results: Compared to controlled patients, those having resistant hypertension were older, more obese and had longer hypertension duration. They also had more frequently diabetes, dyslipidemia, reduced renal function, microalbuminuria, left-ventricular hypertrophy and previous history of cardiovascular events. In multivariate analyses, hypertension duration, obesity, abdominal obesity, left-ventricular hypertrophy, reduced estimated glomerular filtration rate, and microalbuminuria were independently associated with resistant hypertension. Resistant hypertensive patients had higher ambulatory blood pressures, but differences between office and ambulatory blood pressure (white-coat effect) were also more pronounced in this group, revealing a proportion of 40% of patients with normal 24-h blood pressure. On the contrary, values of 24-h blood pressure above 130 and/or 80 mmHg (masked hypertension) were present in 31% of apparently controlled patients. Conclusion: Resistant hypertension is associated with obesity, longer hypertension duration and kidney and cardiac damage. Ambulatory blood pressure monitoring reveals that white-coat hypertension is common among resistant hypertensive patients, as well as is masked hypertension among apparently controlled patients.

Guía Europea de Prevención Cardiovascular en la Práctica Clínica: adaptación Española del CEIPC 2008

espanolPresentamos la adaptacion espanola del Comite Espanol lnterdisciplinario para la Prevencion Cardiovascular (CEIPC) 2008 de la Guia Europea de Prevencion Cardiovascular (IV Cuarto Grupo de Trabajo Conjunto de la ESC y otras sociedades). Esta guia se centra en la prevencion de la enfermedad cardiovascular en su conjunto, incluyendo las distintas manifestaciones clinicas (coronaria, cerebrovascular, periferica y otras) y mantiene la recomendacion del modelo SCORE de bajo riesgo en la poblacion espanola para la valoracion del riesgo cardiovascular global, con un punto de corte en el 5% para definir alto riesgo. El objetivo es prevenir la mortalidad y morbilidad debidas a las ECV, mediante la prevencion y el manejo adecuado de sus factores de riesgo en la practica clinica. Se enfatiza la prevencion primaria basada en la modificacion de los habitos y estilos de vida, buscando o manteniendo el perfil de las personas sanas. Se requiere una intervencion profesional adecuada y duradera, generalmente multidisciplinar, para que la poblacion y los pacientes en riesgo incrementen su actividad fisica, sigan una alimentacion saludable y abandonen el tabaco si son fumadores. Respecto a las guias previas, se subraya el papel del medico y enfermeria de Atencion Primaria, por su proximidad y accesibilidad en los cuidados e intervenciones preventivas y en la promocion de un estilo de vida cardiosaludable. La decision de iniciar el tratamiento para reducir la presion arterial dependera de sus valores, del riesgo cardiovascular y de la existencia o no de lesiones de organos diana o ECV asociada. La meta terapeutica es, en general, PA EnglishWe are pleased to present the Spanish adaptation from the Spanish Committee for Cardiovascular Disease Prevention (CEIPC) of the European Guidelines on Cardiovascular Disease Prevention in Clinical Practice (IV Joint Task Force of the European Society of Cardiology and Other Societies). This guide is focused on the prevention of cardiovascular disease (CVD) as a whole, including coronary, cerebrovascular, periphery and others, recommending the SCORE model for risk assessment with a 5% threshold for the definition of high-risk. We empathize the need of primary prevention based on lifestyle changes included stop smoking, suitable nutrition and diary physical exercise, with the focus on the health people. The objective is to prevent premature mortality and morbidity due to CVD by means of dealing with its related risk factors in clinical practice. A maintained and multidisciplinary professional intervention is required in order to obtain an increase of physical activity, healthy alimentation and smoking cessation in smokers, to the general population and individuals at risk. The decision to start blood pressure treatment will depend upon the BP values, cardiovascular risk and possible damage to target organs or definite CVD. The treatment goal is to achieve BPThe present CEIPC Spanish adaptation of the European Guidelines on Cardiovascular Disease Prevention in Clinical Practice 2008. This guide recommends the SCORE model for risk evaluation. The aim is to prevent premature mortality and morbidity due to CVD by means of dealing with its related risk factors in clinical practice. The guide focuses on primary prevention and emphasizes the role of the nurses and primary care doctors in promoting a healthy life style, based on increasing physical activity, changing dietary habits, and not smoking. The therapeutic goal is to achieve a Blood Pressure < 140/90 mmHg, but in patients with diabetes, chronic kidney disease, or definite CVD, the objective is < 130/80 mmHg. Serum cholesterol should be < 200 mg/dl and cLDL < 130 mg/dl, although in patients with CVD or diabetes, the objective is < 100 mg/dl (80 mg/dl if feasible in very high-risk patients). Patients with type 2 diabetes and those with metabolic syndrome must lose weight and increase their physical activity, and drugs must be administered whenever applicable, with the objective guided by body mass index and waist circumference. In diabetic type 2 patients, the objective is glycated haemoglobin < 7%. Allowing people to know the guides and developing implementation programs, identifying barriers and seeking solutions for them, are priorities for the CEIPC in order to put the recommendations into practice.

Adaptación española de la Guía Europea de Prevención Cardivascular

We are pleased to present the European Guidelines on Cardiovascular Disease Prevention, translated and adapted by the Interdisciplinary Spanish Committee for Cardiovascular Disease Prevention. This guide is focused on the prevention of cardiovascular disease as a whole, recommending the SCORE model for risk assessment and placing priority on the care of patients and high-risk individuals. The objective is to prevent premature death due to CVD by means of dealing with its related risk factors in clinical practice. Hence, a maintained professional intervention is required in order to obtain an increase of physical activity and of healthy diets in patients high-risk individuals, and smoking cessation in smokers. The decision to start blood pressure treatment will depend upon the BP values, cardiovascular risk and possible damage to target organs. The treatment goal is to achieve BP <140/90 mmHg, but among patients with diabetes, chronic kidney disease, a past history of ictus, coronary heart disease or heart failure, lower levels must be pursued. Serum cholesterol must be below 200 mg/dl and LDL cholesterol below 130 mg/dl, although among patients with CVD or diabetes, levels respectively below 175 mg/dl and 100 mg/dl must be pursued. Advice of a professional dietitian is always required in order to keep blood sugar levels controlled. Proper insulin therapy is required in Type I diabetes. Patients with Type II diabetes and those with metabolic syndrome must lose weight and increase their physical activity, drugs being administered wherever applicable. Lastly, an appendix is included providing diet recommendations adapted to our environment and criteria related to referral or seeing a specialist for hypertensive or dyslipemic patients.

Urinary albumin excretion is associated with true resistant hypertension

Resistant (or refractory) hypertension (RH) is a clinical diagnosis based on blood pressure (BP) office measurements. About one third of subjects with suspected RH have indeed pseudo-resistant hypertension and 24-h ambulatory-blood pressure-monitoring aids to precisely identify them. Our aim was to determine those clinical, laboratory or echocardiographic variables that may be associated with subjects with sustained hypertension (namely true RH). We carried out a cross-sectional analysis of 143 patients consecutively enrolled with the clinical diagnosis of RH. All patients underwent clinical-demographic, laboratory evaluation, 2D-echocardiography and 24-h ambulatory-blood pressure-monitoring. Pseudo-resistant hypertension or white-coat RH was defined if office BP was ⩾140 and/or 90 mm Hg and 24-h BP <130/80 mm Hg. One-hundred and three (72%) patients had true RH and 40 (28%) patients had white-coat RH. True RH patients had significantly higher diabetes prevalence and higher office-systolic blood pressure (SBP) levels. Regarding target organ damage, left ventricular mass index (LVMI) and 24-h urinary albumin excretion (UAE) were also higher in true RH after adjustment for possible confounders (P=0.031 and P=0.012, respectively). In a logistic regression analysis, only office-SBP (multivariate OR (95%CI): 1.030 (1.003–1.057), P=0.030) and UAE (multivariate OR (95% CI): 2.376 (1.225–4.608), P=0.010) were independently associated with true RH. We conclude that true resistant hypertension is associated with silent target organ damage, especially UAE. In patients with suspected RH, assessment of 24 h ambulatory BP is the most accurate way to detect a population with high risk for target-organ damage.

Pharmacoeconomic considerations in the management of hypertension.

Hypertension is highly prevalent in developed and developing countries (more than 30% of the adult population when a threshold value of 140/90mm Hg is selected). It constitutes one of the major cardiovascular risk factors and accounts for more than 5% of total deaths worldwide.The economic impact of hypertension is enormous, representing

Implementation of Spanish adaptation of the European guidelines on cardiovascular disease prevention in primary care

US1685 million in Spain in 1994. Direct costs amount to more than 50% of the total costs of hypertension, and almost 70% of these are attributable to drug treatment. Furthermore, hypertensive patients use medical services 50% more than normotensive individuals, and hypertension represents one of the 3 leading causes of visits to primary healthcare centres.When considering the cost effectiveness of hypertension treatment, there is no doubt that it is cost effective in comparison with other interventions, although some controversies exist, mainly with respect to mild-to-moderate hypertension and to the long term versus short term benefits. The controversy about the absolute risk of hypertension influences the cost-effectiveness analysis.Because of the limitations of the available cost-effectiveness analyses, it is currently impossible to recommend the use of any particular antihypertensive drug for all patients with hypertension. Consequently, the choice of antihypertensive in any patient should be guided by clinical experience and the recommendations of the present international guidelines.

Blood pressure reactivity to mental stress task as a determinant of sustained hypertension after 5 years of follow-up.

Microalbuminuria is a known marker of subclinical organ damage. Its prevalence is higher in patients with resistant hypertension than in subjects with blood pressure at goal. On the other hand, some patients with apparently well-controlled hypertension still have microalbuminuria. The current study aimed to determine the relationship between microalbuminuria and both office and 24-hour ambulatory blood pressure. A cohort of 356 patients (mean age 64±11 years; 40.2% females) with resistant hypertension (blood pressure ≥140 and/or 90 mm Hg despite treatment with ≥3 drugs, diuretic included) were selected from Spanish hypertension units. Patients with estimated glomerular filtration rate <30 mL/min/1.73 m2 were excluded. All patients underwent clinical and demographic evaluation, complete laboratory analyses, and good technical-quality 24-hour ambulatory blood pressure monitoring. Urinary albumin/creatinine ratio was averaged from 3 first-morning void urine samples. Microalbuminuria (urinary albumin/creatinine ratio ≥2.5 mg/mmol in males or ≥3.5 mg/mmol in females) was detected in 46.6%, and impaired renal function (estimated glomerular filtration rate <60 mL/min/1.73 m2) was detected in 26.8%. Bivariate analyses showed significant associations of microalbuminuria with older age, reduced estimated glomerular filtration rate, increased nighttime systolic blood pressure, and elevated daytime, nighttime, and 24-hour diastolic blood pressure. In a logistic regression analysis, after age and sex adjustment, elevated nighttime systolic blood pressure (multivariate odds ratio, 1.014 [95% CI, 1.001 to 1.026]; P=0.029) and reduced estimated glomerular filtration rate (multivariate odds ratio, 2.79 [95% CI, 1.57 to 4.96]; P=0.0005) were independently associated with the presence of microalbuminuria. We conclude that microalbuminuria is better associated with increased nighttime systolic blood pressure than with any other office and 24-hour ambulatory blood pressure monitoring parameters.

Determinants of left ventricular mass in untreated mildly hypertensive subjects: hospitalet study in mild hypertension.

BackgroundThe successful implementation of cardiovascular disease (CVD) prevention guidelines relies heavily on primary care physicians (PCPs) providing risk factor evaluation, intervention and patient education. The aim of this study was to ascertain the degree of awareness and implementation of the Spanish adaptation of the European guidelines on CVD prevention in clinical practice (CEIPC guidelines) among PCPs.MethodsA cross-sectional survey of PCPs was conducted in Spain between January and June 2011. A random sample of 1,390 PCPs was obtained and stratified by region. Data were collected by means of a self-administered questionnaire.ResultsMore than half (58%) the physicians were aware of and knew the recommendations, and 62% of those claimed to use them in clinical practice, with general physicians (without any specialist accreditation) being less likely to so than family doctors. Most PCPs (60%) did not assess cardiovascular risk, with the limited time available in the surgery being cited as the greatest barrier by 81%. The main reason to be sceptical about recommendations, reported by 71% of physicians, was that there are too many guidelines. Almost half the doctors cited the lack of training and skills as the greatest barrier to the implementation of lifestyle and behavioural change recommendations.ConclusionsMost PCPs were aware of the Spanish adaptation of the European guidelines on CVD prevention (CEIPC guidelines) and knew their content. However, only one third of PCPs used the guidelines in clinical practice and less than half CVD risk assessment tools.
