A new risk score to assess atrial fibrillation risk in hypertensive patients (ESCARVAL-RISK Project.

This study aimed to assess atrial fibrillation (AF) incidence and predictive factors in hypertensive patients and to formulate an AF risk assessment score that can be used to identify the patients most likely to develop AF. This was a cohort study of patients recruited in primary healthcare centers. Patients aged 40 years or older with hypertension, free of AF and with no previous cardiovascular events were included. Patients attended annual visits according to clinical practice until the end of study or onset of AF. The association between AF incidence and explanatory variables (age, sex, body mass index, medical history and other) was analyzed. Finally, 12,206 patients were included (52.6% men, and mean age was 64.9 years); the mean follow-up was 36.7 months, and 394 (3.2%) patients were diagnosed with AF. The incidence of AF was 10.5/1000 person-years. Age (hazard ratio [HR] 1.06 per year; 95% confidence interval [CI] 1.05-1.08), male sex (HR 1.88; 95% CI 1.53-2.31), obesity (HR 2.57; 95% CI 1.70-3.90), and heart failure (HR 2.44; 95% CI 1.45-4.11) were independent predictors (p < 0.001). We propose a risk score based on significant predictors, which enables the identification of people with hypertension who are at the greatest risk of AF.

Knowledge, availability, and use of ambulatory and home blood pressure monitoring in primary care in Spain: the MAMPA study.

OBJECTIVE: To examine the degree of knowledge and management of automated devices for office blood pressure measurement (AD), home blood pressure monitoring (HBPM) and ambulatory blood pressure monitoring (ABPM) in primary care in Spain. METHODS: Online self-administered survey sent between May 2016 and February 2017 to 2221 primary-care physicians working across Spain. Clinicians were mostly identified through national primary-care scientific societies (20% overall response rate). RESULTS: Participants' mean age was 47.7 years, 55% were women, and 54% reported at least 20 years of primary-care practice. Among them, 47.5% considered ABPM the best diagnostic method for hypertension, 23% chose HBPM, and 7.1% chose office blood pressure. Also, 78.2% had AD available at their centers and 49.0% had ABPM, with slight urban/rural differences. HBPM was recommended in daily practice for hypertension diagnosis by 67% of participants, whereas 30% recommended ABPM. Cost to the patients was the main reason for not using HBPM (42.7%) as was lack of accessibility for not using ABPM (69.8%). Lack of specific training was also reported as an important reason in both cases. CONCLUSION: Even in the possibly best primary care scenario presented by highly motivated physicians (respondents to a voluntary anonymous survey), enormous gaps were observed between current guidelines' recommendations on ABPM and HBPM use for confirming hypertension and the modest degree of knowledge, availability, and use of these technologies.

Influence of renal function on anticoagulation control in patients with non-valvular atrial fibrillation taking vitamin K antagonists.

BACKGROUND AND PURPOSE: Chronic kidney disease (CKD) has been related to poor anticoagulation control and an increased risk of bleeding. This study aims to evaluate the association between impaired renal function (eGFR <60 mL/min/1.73 m2 ) and anticoagulation control in patients with non-valvular atrial fibrillation (AF) on vitamin K antagonists (VKA) therapy. We also assessed whether the predictive value of the SAMe-TT2 R2 score prevailed for subgroups both with and without CKD. METHODS: This is an ancillary analysis of 1381 patients from the PAULA study, which was a cross-sectional, retrospective and nationwide multicenter study. RESULTS: A total of 370 patients had eGFR <60 mL/min/1.73 m2 . Anticoagulation control levels progressively worsened across each stage of CKD. Multiple linear regression analysis showed CKD as an independent predictor of time in therapeutic range (TTR). In the subgroup of patients with preserved renal function, female sex, diet affecting INR, polypharmacy and amiodarone were associated with poorer TTR. The SAMe-TT2 R2 score had a significant but modest predictive value for TTR<65% (AUC, area under the curve 0.558, P = .002). In the subgroup of patients with CKD, the SAMe-TT2 R2 (>2 points) showed no significant predictive capacity for TTR (AUC 0.528, P = .354). The average TTR was similar for both sexes (P = .255), but with a higher percentage of males subjects with TTR ≥65% (P = .013). CONCLUSION: Chronic kidney disease is associated with poor anticoagulation control in patients with non-valvular AF taking VKA. The SAMe-TT2 R2 score was not predictive of poor TTR in the subgroup with CKD, although a modest predictive value for poor TTR was found in those without CKD.

Evaluation of SAMe-TT2R2 score and other clinical factors influencing the quality of anticoagulation therapy in non-valvular atrial fibrillation: a nationwide study in Spain.

OBJECTIVE: To assess the major clinical factors affecting the quality of anticoagulation and evaluate the predictive value of the SAMe-TT2R2 score to identify patients who will achieve a high average time in therapeutic range (T.T.R.) with vitamin K antagonist (V.K.A.) treatment. RESEARCH DESIGN AND METHODS: This observational, cross-sectional, retrospective and nationwide multicenter study included 1524 patients from the primary care setting with non-valvular atrial fibrillation receiving V.K.A. (≥12 months). We performed a bivariate analysis to identify factors individually associated with the T.T.R. and a multiple regression analysis to identify the independent predictive factors. For the validation of the SAMe-TT2R2 score, the receiver operating characteristic (R.O.C.) curve was calculated and the Hosmer-Lemeshow test was used to test calibration. RESULTS: A total of 94.8% of patients received acenocumarol (4.8% warfarin). A progressive decrease in mean T.T.R. was found when the SAMe-TT2R2 score increased from 0 points (72.1 ± 17.1%) to 4 points (64.1 ± 23.2%), p < 0.001. Other risk scores (CHADS2 and CHA2DS2-VASc, HAS-BLED) were also associated with the mean T.T.R. We found a significant association between low T.T.R. and the following clinical factors: female sex, three or more comorbidities, amiodarone treatment, dietary habits, bleeding history and the intake of ≥7 tablets per day besides V.K.A. (p < 0.01). Regarding SAMe-TT2R2 score validation, the R.O.C. curve showed significant capability, although not high, of discriminating good anticoagulation control (T.T.R. ≥65%) with an area under the curve of 0.562 (95% C.I. 0.533-0.592, p < 0.001) which increased, remaining modest, to 0.594 (95% C.I. 0.564-0.624, p < 0.001) when the factors not included in SAMe-TT2R2 score were added. CONCLUSION: In this cohort, the SAMe-TT2R2 score had a significant, although modest, ability to assess the likelihood of good international normalized ration (I.N.R.) control, and its predictive value might slightly improve by adding other simple clinical factors. Further research is needed to refine the predictive scales.

Barriers to improved dyslipidemia control: Delphi survey of a multidisciplinary panel.

OBJECTIVE: To assess the barriers that make it difficult for the health care professionals (physicians, nurses and health care managers) to achieve a better control for dyslipidemia in Spain. METHODS: The study has an observational design and was performed using the modified Delphi technique. One hundred and forty-nine panel members from medicine, nursing and health care management fields and from different Spanish regions were selected randomly and were invited to participate. Individual and anonymous opinions were asked by answering a 42-items questionnaire via e-mail (two rounds were done). Level of agreement was assessed using measures of central tendency and dispersion. We analysed commonalities/differences between the three groups (Kappa index and McNemar chi-square). RESULTS: Response rate: 81%. The agreement index was 33.3 (95% CI: 18.9-47.7). Regarding the non-compliance with therapy, it improves with patient education degree in dyslipidemia, patient motivation, the agreement on decisions with the patient and with the use of cardiovascular risk measure and it gets worse with lack of information on the objectives to achieve. Clinical inertia improves with professional's motivation, cardiovascular risk calculation, training on objectives and the use of indicators and it gets worse with lack of treatment goals. CONCLUSION: Different perceptions and attitudes between medicine, nursing and health care management were found. An agreement in interventions in non-compliance and clinical inertia to improve dyslipidemia control was reached.

[Atrial fibrillation: from detection to treatment. Role of the family physician, cardiologist and other specialists. New models of clinical management]. / Fibrilación auricular: de la detección al tratamiento. Papel del médico de familia, del cardiólogo y de otros especialistas. Nuevos modelos de gestión clínica.

The prevalence of atrial fibrillation (AF) in adults in Spain is estimated to be 4.4% of the population aged 40 years or more, corresponding to a mean of 30 to 40 patients per family physician. The importance of this common arrhythmia lies, above all, in its close association with stroke and other systemic embolisms, among other possible complications. Diagnosis of AF is based on electrocardiographic recording and can consequently be made by the family physician, who should make an overall assessment of the patient's health, including risk factors, comorbidity and type of AF and evaluate embolic and hemorrhagic risk. The decision to prescribe anticoagulation therapy or not should be taken promptly and should be based on the patient's embolic risk and not on the type of arrhythmia. In addition, the family physician, together with the treating cardiologist, should decide on the most appropriate therapeutic strategy for each individual patient: a rhythm control strategy (attempting to recover and maintain sinus rhythm) or a rate control strategy (maintaining heart rate within acceptable limits). Antithrombotic treatment should form part of both strategies, since stroke is the most serious and common complication of AF and also has the greatest effects on morbidity and mortality. Moreover, cardioembolic strokes (accounting for one out of every four strokes) are especially devastating, with the highest fatality, hospital and social resource use, and associated disability. Control of AF and particularly stroke prevention with adequate anticoagulation should be carried out mainly in primary care. Nevertheless, multidisciplinary management is required in most patients, which requires effective coordination between primary and specialized care, especially cardiology, hematology and neurology (in patients who have already had a stroke).

[Validity and usefulness of B-type natriuretic peptide (BNP) for early detection of left ventricular dysfunction in high-risk patients in primary care]. / Validez y utilidad del péptido ventricular natriurético tipo B (BNP) en la detección de disfunción ventricular izquierda en pacientes de alto riesgo en atención primaria.

OBJECTIVE: The aim of this study was to determine the accuracy of BNP test for early diagnosis of left ventricular dysfunction in patients at high-risk for heart failure. DESIGN: Cross-sectional descriptive study. SETTING: 7 Primary Care Centres in Madrid (Spain). PARTICIPANTS: A consecutive sample of 204 consecutive asymptomatic patients with high risk for heart failure (Stages A-B, AHA/ACC Classification). MAIN MEASUREMENTS: BNP plasma levels were measured in the clinical setting using Triage BNP Test(®) (Biosite(®)) and an echocardiography was performed in the following 3 days in a single hospital unit as a reference standard. Plasma BNP levels were compared depending on the presence/absence of left ventricular dysfunction (LVD), type and severity degree. Sensitivity, specificity, positive and negative predictive values, and Área under the receiver operating characteristic curve (ROC) for BNP assay were calculated. RESULTS: BNP values were significantly higher (P<.001) in patients with left ventricular systolic dysfunction (LVSD). No significant differences were found for diastolic dysfunction. The best cut-off value to discriminate the patients with LVSD was 71.00 pg/ml, with an Área under the ROC curve of 0.757 (95% CI 0.64-0.87). Sensitivity for LVD diagnosis was 75% (95% CI 50.66-99.34), specificity 70.19% (95% CI 62.81-77.57), positive predictive value (PPV) 20% (95% CI 9.05-30.95), and negative predictive value (NPV) 96.58% (95% CI 92.86-100), with LVSD prevalence of 9.04% in this population. CONCLUSIONS: BNP determinations are of value in diagnosing LVSD in a primary care setting, with similar sensitivities and specificities. Due to the high NPV is useful to rule-out patients for echocardiography.

[European Guidelines on Cardiovascular Disease Prevention in Clinical Practice. CEIPC 2008 Spanish Adaptation]. / Guía Europea de Prevención Cardiovascular en la Práctica Clínica. Adaptación española del CEIPC 2008.

The 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<140/90mmHg, but in patients with diabetes, chronic kidney disease, or definite CVD, the objective is<130/80mmHg. Serum cholesterol should be<200mg/dl and cLDL<130mg/dl, although in patients with CVD or diabetes, the objective is<100mg/dl (80mg/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.
