RESUMEN

BACKGROUND AND AIMS: Guidelines suggest similar blood pressure (BP) targets in patients with and without diabetes and recommend ambulatory BP monitoring (ABPM) to diagnose and classify hypertension. It was explored whether different levels of ambulatory and office BP and different hypertension phenotypes associate with differences of risk in diabetes and no diabetes. METHODS: This analysis assessed outcome data from the Spanish ABPM Registry in 59 124 patients with complete available data. The associations between office, mean, daytime, and nighttime ambulatory BP with the risk in patients with or without diabetes were explored. The effects of diabetes on mortality in different hypertension phenotypes, i.e. sustained hypertension, white-coat hypertension, and masked hypertension, compared with normotension were studied. Analyses were done with Cox regression analyses and adjusted for demographic and clinical confounders. RESULTS: A total of 59 124 patients were recruited from 223 primary care centres in Spain. The majority had an office systolic BP >140 mmHg (36 700 patients), and 23 128 (40.6%) patients were untreated. Diabetes was diagnosed in 11 391 patients (19.2%). Concomitant cardiovascular (CV) disease was present in 2521 patients (23.1%) with diabetes and 4616 (10.0%) without diabetes. Twenty-four-hour mean, daytime, and nighttime ambulatory BP were associated with increased risk in diabetes and no diabetes, while in office BP, there was no clear association with no differences with and without diabetes. While the relative association of BP to CV death risk was similar in diabetes compared with no diabetes (mean interaction P = .80, daytime interaction P = .97, and nighttime interaction P = .32), increased event rates occurred in diabetes for all ABPM parameters for CV death and all-cause death. White-coat hypertension was not associated with risk for CV death (hazard ratio 0.86; 95% confidence interval 0.72-1.03) and slightly reduced risk for all-cause death in no diabetes (hazard ratio 0.89; confidence interval 0.81-0.98) but without significant interaction between diabetes and no diabetes. Sustained hypertension and masked hypertension in diabetes and no diabetes were associated with even higher risk. There were no significant interactions in hypertensive phenotypes between diabetes and no diabetes and CV death risk (interaction P = .26), while some interaction was present for all-cause death (interaction P = .043) and non-CV death (interaction P = .053). CONCLUSIONS: Diabetes increased the risk for all-cause death, CV, and non-CV death at every level of office and ambulatory BP. Masked and sustained hypertension confer to the highest risk, while white-coat hypertension appears grossly neutral without interaction of relative risk between diabetes and no diabetes. These results support recommendations of international guidelines for strict BP control and using ABPM for classification and assessment of risk and control of hypertension, particularly in patients with diabetes. CLINICAL TRIAL REGISTRATION: Not applicable.

RESUMEN

BACKGROUND: Ambulatory blood pressure provides a more comprehensive assessment than clinic blood pressure, and has been reported to better predict health outcomes than clinic or home pressure. We aimed to examine associations of clinic and 24-h ambulatory blood pressure with all-cause and cardiovascular mortality in a large cohort of primary care patients referred for assessment of hypertension. METHODS: We did an observational cohort study using clinic and ambulatory blood pressure data obtained from March 1, 2004, to Dec 31, 2014, from the Spanish Ambulatory Blood Pressure Registry. This registry included patients from 223 primary care centres from the Spanish National Health System in all 17 regions of Spain. Mortality data (date and cause) were ascertained by a computerised search of the vital registry of the Spanish National Institute of Statistics. Complete data were available for age, sex, all blood pressure measures, and BMI. For each study participant, follow-up was from the date of their recruitment to the date of death or Dec 31, 2019, whichever occurred first. Cox models were used to estimate associations between usual clinic or ambulatory blood pressure and mortality, adjusted for confounders and additionally for alternative measures of blood pressure. For each measure of blood pressure, we created five groups (ie, fifths) defined by quintiles of that measure among those who subsequently died. FINDINGS: During a median follow-up of 9·7 years, 7174 (12·1%) of 59 124 patients died, including 2361 (4·0%) from cardiovascular causes. J-shaped associations were observed for several blood pressure measures. Among the top four baseline-defined fifths, 24-h systolic blood pressure was more strongly associated with all-cause death (hazard ratio [HR] 1·41 per 1 - SD increment [95% CI 1·36-1·47]) than clinic systolic blood pressure (1·18 [1·13-1·23]). After adjustment for clinic blood pressure, 24-h blood pressure remained strongly associated with all-cause deaths (HR 1·43 [95% CI 1·37-1·49]), but the association between clinic blood pressure and all-cause death was attenuated when adjusted for 24-h blood pressure (1·04 [1·00-1·09]). Compared with the informativeness of clinic systolic blood pressure (100%), night-time systolic blood pressure was most informative about risk of all-cause death (591%) and cardiovascular death (604%). Relative to blood pressure within the normal range, elevated all-cause mortality risks were observed for masked hypertension (HR 1·24 [95% CI 1·12-1·37]) and sustained hypertension (1·24 [1·15-1·32]), but not white-coat hypertension, and elevated cardiovascular mortality risks were observed for masked hypertension (1·37 [1·15-1·63]) and sustained hypertension (1·38 [1·22-1·55]), but not white-coat hypertension. INTERPRETATION: Ambulatory blood pressure, particularly night-time blood pressure, was more informative about the risk of all-cause death and cardiovascular death than clinic blood pressure.

RESUMEN

BACKGROUND: Evidence for the influence of ambulatory blood pressure on prognosis derives mainly from population-based studies and a few relatively small clinical investigations. This study examined the associations of blood pressure measured in the clinic (clinic blood pressure) and 24-hour ambulatory blood pressure with all-cause and cardiovascular mortality in a large cohort of patients in primary care. METHODS: We analyzed data from a registry-based, multicenter, national cohort that included 63,910 adults recruited from 2004 through 2014 in Spain. Clinic and 24-hour ambulatory blood-pressure data were examined in the following categories: sustained hypertension (elevated clinic and elevated 24-hour ambulatory blood pressure), "white-coat" hypertension (elevated clinic and normal 24-hour ambulatory blood pressure), masked hypertension (normal clinic and elevated 24-hour ambulatory blood pressure), and normotension (normal clinic and normal 24-hour ambulatory blood pressure). Analyses were conducted with Cox regression models, adjusted for clinic and 24-hour ambulatory blood pressures and for confounders. RESULTS: During a median follow-up of 4.7 years, 3808 patients died from any cause, and 1295 of these patients died from cardiovascular causes. In a model that included both 24-hour and clinic measurements, 24-hour systolic pressure was more strongly associated with all-cause mortality (hazard ratio, 1.58 per 1-SD increase in pressure; 95% confidence interval [CI], 1.56 to 1.60, after adjustment for clinic blood pressure) than the clinic systolic pressure (hazard ratio, 1.02; 95% CI, 1.00 to 1.04, after adjustment for 24-hour blood pressure). Corresponding hazard ratios per 1-SD increase in pressure were 1.55 (95% CI, 1.53 to 1.57, after adjustment for clinic and daytime blood pressures) for nighttime ambulatory systolic pressure and 1.54 (95% CI, 1.52 to 1.56, after adjustment for clinic and nighttime blood pressures) for daytime ambulatory systolic pressure. These relationships were consistent across subgroups of age, sex, and status with respect to obesity, diabetes, cardiovascular disease, and antihypertensive treatment. Masked hypertension was more strongly associated with all-cause mortality (hazard ratio, 2.83; 95% CI, 2.12 to 3.79) than sustained hypertension (hazard ratio, 1.80; 95% CI, 1.41 to 2.31) or white-coat hypertension (hazard ratio, 1.79; 95% CI, 1.38 to 2.32). Results for cardiovascular mortality were similar to those for all-cause mortality. CONCLUSIONS: Ambulatory blood-pressure measurements were a stronger predictor of all-cause and cardiovascular mortality than clinic blood-pressure measurements. White-coat hypertension was not benign, and masked hypertension was associated with a greater risk of death than sustained hypertension. (Funded by the Spanish Society of Hypertension and others.).

RESUMEN

Many patients are hypertensive at the medical settings but show normal blood pressure out of the doctor's office, and are classified as white-coat hypertensives. On the other hand, many patients with controlled hypertension at the clinic show ambulatory blood pressure levels above the thresholds considered for an adequate blood pressure control, known as having masked hypertension. Using data from the Spanish Ambulatory Blood Pressure Monitoring Registry (Spanish ABPM Registry), a national program developed to promote the use of the ambulatory technique for hypertension management in daily practice, we have reviewed the main strengths of this approach, that is the ability to detect discrepancies of blood pressure status with respect to office blood pressure measurement, and to better assess accurate rates of hypertension control. White-coat hypertension within patients with elevated office blood pressure, and masked hypertension within office-controlled patients affected one of three patients in each office status. On the other hand, rates of ambulatory blood pressure control (50%) doubled those of office blood pressure control (25%), still remaining half the patients uncontrolled. We think that a systematic use of ambulatory blood pressure monitoring, and strategies to improve blood pressure control constitute key priorities in hypertension management.

RESUMEN

There is scarce information regarding ambulatory blood pressure (BP) achieved in daily practice with a wide range of antihypertensive drug combinations. We looked for differences in office and ambulatory BP among major drug combinations of two and three antihypertensive agents from a different drugs class. A total of 17187 patients treated with six types of two-drug combinations and 9724 treated with six types of three-drug combinations from the Spanish ABPM Registry were analyzed. We compared achieved office and ambulatory BP, as well as office (< 140/90 mmHg) and ambulatory (24-hour BP < 130/80; day BP < 135/85, and night BP < 120/70 mmHg) BP control among groups. The combination of renin-angiotensin system (RAS) blockers with diuretics and the triple combination of RAS blockers with diuretics and calcium channel blockers (CCB) were associated with lower values of 24-hour, daytime and nighttime BP, as well as more pronounced nocturnal BP dip. Compared with such combinations (reference), other double combinations had lower rates of ambulatory BP control. Moreover, triple combinations containing alpha blockers also had lower rates of ambulatory BP control. We conclude that even with similar office BP control, differences exist among antihypertensive two-drug and three-drug combinations with respect to ambulatory BP control achieved during treatment, with RAS blockers/diuretics and RAS blockers/CCBs/diuretics obtaining better control rates. This can help physicians choose among drug combinations in order to obtain further ambulatory BP reductions.

RESUMEN

PURPOSE OF REVIEW: There is currently much interest in the usefulness of out-of-office blood pressure (BP) for the diagnosis and the management of hypertension in patients with chronic kidney disease (CKD). This is not to suggest that office BP should be disregarded and we will take the opportunity to stress how it could be improved. RECENT FINDINGS: Arterial hypertension constitutes a very relevant cardiovascular and renal risk factor in patients with CKD. To assess this risk, the best tool is ambulatory BP monitoring (ABPM), as it allows the detection of masked hypertension, masked untreated hypertension (MUCH) and nondipping pattern, conditions known to be associated with target organ damage that further contributes to increased risk to the patient. Home BP monitoring (HBPM) cannot fully substitute for ABPM because of the absence of BP data during the night. Despite this, there are good reasons to use HBPM systematically in patients with CKD during long-term follow-up. SUMMARY: In the individual patient office, BP may significantly differ from out-of-office measurements. This shortcoming can be attenuated by repeated measurement at every visit, but even if office BP is considered normal, it is still highly desirable to obtain out-of-office data.

RESUMEN

AIM: There are limited data on the quality of treated blood pressure (BP) control during normal daily life, and in particular, the prevalence of 'masked uncontrolled hypertension' (MUCH) in people with treated and seemingly well-controlled BP is unknown. This is important because masked hypertension in 'treatment naïve' patients is associated with a high risk of cardiovascular events. We therefore conducted the first study to define the prevalence and characteristics of MUCH among a large sample of hypertensive patients in routine clinical practice in whom BP was treated and controlled to recommended clinic BP goals. METHODS AND RESULTS: We analysed data from the Spanish Society of Hypertension ambulatory blood pressure monitoring (ABPM) Registry and identified patients with treated and controlled BP according to current international guidelines (clinic BP <140/90 mmHg). Masked uncontrolled hypertension was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP ≥130 mmHg and/or 24-h diastolic BP ≥80 mmHg). From 62 788 patients with treated BP in the Spanish registry, we identified 14 840 with treated and controlled clinic BP, of whom 4608 patients (31.1%) had MUCH according to 24-h ABPM criteria (mean age 59.4 years, 59.7% men). The prevalence of MUCH was significantly higher in males, patients with borderline clinic BP (130-9/80-9 mmHg), and patients at high cardiovascular risk (smokers, diabetes, obesity). Masked uncontrolled hypertension was most often because of poor control of nocturnal BP, with the proportion of patients in whom MUCH was solely attributable to an elevated nocturnal BP almost double that solely attributable to daytime BP elevation (24.3 vs. 12.9%, P < 0.001). CONCLUSION: The prevalence of masked suboptimal BP control in patients with treated and well-controlled clinic BP is high. Clinic BP monitoring alone is thus inadequate to optimize BP control because many patients have an elevated nocturnal BP. These findings suggest that ABPM should become more routine to confirm BP control, especially in higher risk groups and/or those with borderline control of clinic BP.

RESUMEN

BACKGROUND AND AIMS: Whether bedtime versus morning administration of antihypertensive therapy is beneficial on outcomes is controversial. We evaluated the risk of total and cardiovascular mortality in a very large observational cohort of treated hypertensive patients, according to the timing of their usual treatment administration (morning versus evening). METHODS: Vital status and cause of death were obtained from death certificates of 28 406 treated hypertensive patients (mean age 62 years, 53% male individuals), enrolled in the Spanish Ambulatory Blood Pressure Monitoring (ABPM) Registry between 2004 and 2014. Among the 28 406 patients, most (86%) received their medication exclusively in the morning; whilst 13% were treated exclusively in the evening or at bedtime. Follow-up was for a median of 9.7 years and 4345 deaths occurred, of which 1478 were cardiovascular deaths. RESULTS: Using Cox-models adjusted for clinical confounders and 24-h SBP, and compared with patients treated in the morning (reference group), all-cause mortality [hazard ratio 1.01; 95% CI 0.93-1.09) and cardiovascular mortality (hazard ratio 1.04; 95% CI 0.91-1.19) was not significantly different in those receiving evening medication dosing. The results were consistent in all the subgroups of patients analysed. CONCLUSION: In this very large observational study, morning versus bedtime dosing of antihypertensive medication made no difference to the subsequent risk of all-cause or cardiovascular mortality. These findings are in accordance with results from a recent randomized controlled trial and do not support the hypothesis of a specific beneficial effect of night-time antihypertensive treatment dosing on risk of all-cause or cardiovascular death.

RESUMEN

OBJECTIVE: It has been suggested that a blunted nocturnal blood pressure (BP) decline is associated with a poor prognosis. Nevertheless, it remains unclear if an abnormal dipping is deleterious per se or it merely reflects an elevated BP during sleep. We aimed to assess the prognostic value of nocturnal BP decline, with or without concomitant elevated nocturnal BP. METHODS: Vital status and cause of death were obtained from death certificates in 59 124 patients, enrolled in the Spanish ABPM Registry between 2004 and 2014 (median follow-up: 10 years). The association between night-to-day ratio (NDR) and dipping patterns (extreme dippers, dippers, reduced dippers, and risers) with all-cause and cardiovascular mortality were evaluated by Cox-proportional models adjusted for clinical confounders and 24 h blood pressure. RESULTS: NDR was associated with all-cause mortality [hazard ratio for 1SD change: 1.15; 95% confidence interval (CI) 1.13-1.17]. Reduced dippers (1.13; 1.06-1.20) and risers (1.41; 1.32-1.51) were associated with an increased risk of all-cause death, whereas extreme dippers (0.90; 0.79-1.02) were not. Elevated NDR (≥0.9) in the absence of elevated night SBP (<120 mmHg) was associated with an increased risk of death (1.13; 1.04-1.22), as well as elevated night SBP but normal NDR (1.38; 1.26-1.50), and the combination of both abnormalities (1.56; 1.46-1.66). Similar results were obtained for cardiovascular mortality. CONCLUSION: Abnormalities in the circadian pattern are associated with an increased risk of all-cause and cardiovascular mortality. This is maintained even in the absence of nocturnal BP elevation.

RESUMEN

BACKGROUND: The prognostic relevance of short-term blood pressure (BP) variability in hypertension is not clearly established. We aimed to evaluate the association of short-term BP variability, with all-cause and cardiovascular mortality in a large cohort of patients with hypertension. METHODS: We selected 59 124 patients from the Spanish Ambulatory Blood Pressure Monitoring Registry from 2004 to 2014 (median follow-up: 9.7 years). Systolic and diastolic BP SD and coefficient of variation from daytime and nighttime, weighted SD, weighted coefficient of variation, average real variability (mean of differences between consecutive readings), and BP variability ratio (ratio between systolic and diastolic 24-hour SD) were calculated through baseline 24-hour ambulatory BP monitoring. Association with all-cause and cardiovascular mortality were assessed by Cox regression models adjusted for clinical confounders and BP. RESULTS: Patients who died during follow-up had higher values of BP variability compared with those remaining alive. In adjusted models systolic and diastolic daytime and weighted SD and coefficient of variation, average real variability, as well as systolic nighttime SD and BP variability ratio were all significantly associated with all-cause and cardiovascular mortality. Hazard ratios for 1-SD increase in the systolic components ranged from 1.05 to 1.12 for all-cause mortality and from 1.07 to 1.17 for cardiovascular mortality. A daytime SD≥13 mm Hg, a nighttime and a weighted SD≥12 mm Hg, and an average real variability ≥10 mm Hg, all systolic, were independently associated with mortality. CONCLUSIONS: Short-term blood pressure variability shows a relatively weak but significant association with all-cause and cardiovascular mortality in patients with hypertension.

RESUMEN

Up to 50% of patients admitted for heart failure (HF) have congestion at discharge despite diagnostic and therapeutic advances. Both persistent congestion and diuretic resistance are associated with worse prognosis. The combination of hypertonic saline and loop diuretic has shown promising results in different studies. However, it has not yet achieved a standardized use, partly because of the great heterogeneity in the concentration of sodium chloride, the dose of diuretic or the amount of sodium in the diet. Classically, the movement of water from the intracellular space due to an increase in extracellular osmolarity has been postulated as the main mechanism involved. However, chloride deficit is postulated as the main up-regulator of plasma volume changes, and its correction may be the main mechanism involved. This "chloride centric" approach to heart failure opens the door to therapeutic strategies that would include diuretics to correct hypochloremia, as well as sodium free chloride supplementation.

RESUMEN

BACKGROUND: Quantification of total cardiovascular risk is essential for individualizing hypertension treatment. This study aimed to develop and validate a novel, machine-learning-derived model to predict cardiovascular mortality risk using office blood pressure (OBP) and ambulatory blood pressure (ABP). METHODS: The performance of the novel risk score was compared with existing risk scores, and the possibility of predicting ABP phenotypes utilizing clinical variables was assessed. Using data from 59 124 patients enrolled in the Spanish ABP Monitoring registry, machine-learning approaches (logistic regression, gradient-boosted decision trees, and deep neural networks) and stepwise forward feature selection were used. RESULTS: For the prediction of cardiovascular mortality, deep neural networks yielded the highest clinical performance. The novel mortality prediction models using OBP and ABP outperformed other risk scores. The area under the curve achieved by the novel approach, already when using OBP variables, was significantly higher when compared with the area under the curve of the Framingham risk score, Systemic Coronary Risk Estimation 2, and Atherosclerotic Cardiovascular Disease score. However, the prediction of cardiovascular mortality with ABP instead of OBP data significantly increased the area under the curve (0.870 versus 0.865; P=3.61×10-28), accuracy, and specificity, respectively. The prediction of ABP phenotypes (ie, white-coat, ambulatory, and masked hypertension) using clinical characteristics was limited. CONCLUSIONS: The receiver operating characteristic curves for cardiovascular mortality using ABP and OBP with deep neural network models outperformed all other risk metrics, indicating the potential for improving current risk scores by applying state-of-the-art machine learning approaches. The prediction of cardiovascular mortality using ABP data led to a significant increase in area under the curve and performance metrics.

RESUMEN

BACKGROUND: Previous studies have examined control rates of office blood pressure (BP) in chronic kidney disease (CKD). However, recent evidence suggests major discrepancies between office and 24-hour BP values in hypertensive populations. This study examined concordance/discordance between office- and ambulatory-based BP control in a large cohort of patients with CKD. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: 5,693 hypertensive individuals with CKD stages 1-5 from the Spanish ABPM (ambulatory BP monitoring) Registry. PREDICTORS: Thresholds of 140/90 and 130/80 mm Hg for office BP and 24-hour ambulatory BP, respectively. Age, sex, body mass index, waist circumference, hypertension duration, kidney measures, diabetes, dyslipidemia, target-organ damage, and cardiovascular comorbid conditions. OUTCOMES: Misclassification of BP control as "white-coat" hypertension (office BP ≥140/90 mm Hg, 24-hour BP <130/80 mm Hg) or masked hypertension (office BP <140/90 mm Hg, 24-hour BP ≥130/80 mm Hg). MEASUREMENTS: Standardized office-based BP and 24-hour ABPM. RESULTS: Mean age was 61.0 ± 13.9 (SD) years and 52.6% were men. The proportion with white-coat hypertension was 28.8% (36.8% of patients with office BP ≥140/90 mm Hg) and that of masked hypertension was 7.0% (but 32.1% of patients with office BP <140/90 mm Hg). Female sex, aging, obesity, and target-organ damage were associated with white-coat hypertension; aging and obesity were associated with masked hypertension. Only 21.7% and 8.1% of the CKD population had office BP <140/90 and <130/80 mm Hg, respectively. In contrast, 43.5% of individuals had average 24-hour BP <130/80 mm Hg. LIMITATIONS: Cross-sectional design, longitudinal associations cannot be established. CONCLUSIONS: Misclassification of BP control at the office was observed in 1 of 3 hypertensive patients with CKD. Ambulatory-based control rates were far better than office-based rates. Nevertheless, the burden of uncontrolled ambulatory BP and misclassification of BP control at the office constitutes a call for wider use of ABPM to evaluate the success of hypertension treatment in patients with CKD.

RESUMEN

INTRODUCTION: People with a reduced nighttime dip in blood pressure have an increased cardiovascular risk. Our objective was to describe the different patterns in blood pressure (BP) among pediatricians who work in long on-duty shifts in relation with sex, medical rank and sleeping time. METHODS: Descriptive, cross-sectional, two-center study. On duty pediatric Resident physicians and pediatric Consultants were recruited between January 2018 and December 2021. RESULTS: Fifty-one physicians were included in the study (78.4% female, 66.7% Resident physicians). Resident physicians had a higher night/day ratio (0.91 vs 0.85; p<0.001) and a shorter nighttime period (3.87 vs 5.41, p<0.001) than Consultants. Physicians sleeping less than 5h had a higher night/day ratio (0.91 vs 0.87, p=0.014). Being a Resident showed a ∼4.5-fold increased risk of having a non-dipping BP pattern compared to Consultants. CONCLUSION: We found a potential link between both being a Resident and, probably, having shorter sleeping time, and the non-dipping BP pattern in physicians during prolonged shifts.

RESUMEN

Ambulatory blood pressure (BP) is associated with mortality, but it is also interesting to expand its association with cardiovascular morbidity. This study sought to evaluate association with cardiovascular morbidity and cardiovascular mortality. Patients without cardiovascular disease who had a first 24-hour ambulatory BP monitoring were followed-up until the onset of the first event (a combined variable of cardiovascular mortality, coronary heart disease, cerebrovascular disease, peripheral arteriopathy, or hospital admission for heart failure). Changes in antihypertensive treatment couldn't be collected. Cox regression analysis was adjusted for risk factors and office BP. We included 3907 patients (mean age, 58.0, SD 13.8 years), of whom 85.5% were hypertensive. The follow up period was 6.6 (95% CI 5.0-8.5) years. A total of 496 (12.7%) events were recorded. The incidence rate was 19.3 (95% CI 17.7-21.1) cases per 1000 person-years. The patients with an event compared to the rest of patients were mostly men, older, with higher office and ambulatory systolic BP, higher prevalence of diabetes, chronic kidney disease, dyslipidemia, and non-dipper or riser circadian profile. In the fully adjusted model, office BP loses its significant association with the main variable. Ambulatory BP association remained significant with cardiovascular morbidity and mortality, HR 1.494 (1.326-1.685) and 0.767 (0.654-0.899) for 24-hour systolic and diastolic BP, respectively. Nighttime systolic BP also maintained this significant association, 1.270 (1.016-1.587). We conclude that nighttime systolic BP and 24-hour BP are significantly associated with cardiovascular events and cardiovascular mortality in patients without cardiovascular disease attended under conditions of routine clinical practice.

RESUMEN

We present the Spanish adaptation of the 2021 European Guidelines on Cardiovascular Disease (CVD) prevention in clinical practice. The current guidelines besides the individual approach greatly emphasize on the importance of population level approaches to the prevention of cardiovascular diseases. Systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. Regarding LDL-Cholesterol, blood pressure, and glycemic control in patients with diabetes mellitus, goals and targets remain as recommended in previous guidelines. However, it is proposed a new, stepwise approach (Step 1 and 2) to treatment intensification as a tool to help physicians and patients pursue these targets in a way that fits patient profile. After Step 1, considering proceeding to the intensified goals of Step 2 is mandatory, and this intensification will be based on 10-year CVD risk, lifetime CVD risk and treatment benefit, comorbidities and patient preferences. The updated SCORE algorithm-SCORE2, SCORE-OP- is recommended in these guidelines, which estimates an individual's 10-year risk of fatal and non-fatal CVD events (myocardial infarction, stroke) in healthy men and women aged 40-89 years. Another new and important recommendation is the use of different categories of risk according different age groups (< 50, 50-69, ≥70 years). Different flow charts of CVD risk and risk factor treatment in apparently healthy persons, in patients with established atherosclerotic CVD, and in diabetic patients are recommended. Patients with chronic kidney disease are considered high risk or very high-risk patients according to the levels of glomerular filtration rate and albumin-to-creatinine ratio. New lifestyle recommendations adapted to the ones published by the Spanish Ministry of Health as well as recommendations focused on the management of lipids, blood pressure, diabetes and chronic renal failure are included.

RESUMEN

This document summarises the evidence regarding the association between adverse pregnancy outcomes (APOs), such as hypertensive disorders, preterm birth, gestational diabetes, fetal growth defects (small for gestational age and/or fetal growth restriction), placental abruption, fetal loss, and the risk that a pregnant individual in developing vascular risk factors (VR) that may lead to future vascular disease (VD): coronary heart disease, stroke, peripheral vascular disease, and heart failure. Furthermore, this document emphasises the importance of recognising APOs when assessing VR in women. A history of APOs serves as a sufficient indicator for primary prevention of VD. In fact, adopting a healthy diet and increasing physical activity among women with APOs, starting during pregnancy and/or postpartum, and maintaining it throughout life are significant interventions that can reduce VR. On the other hand, breastfeeding can also reduce the future VR of women, including a lower risk of mortality. Future studies evaluating the use of aspirin, statins, and metformin, among others, in women with a history of APOs could strengthen recommendations regarding pharmacotherapy for primary prevention of VD in these patients. Various healthcare system options exist to improve the transition of care for women with APOs between different healthcare professionals and implement long-term VR reduction strategies. One potential process could involve incorporating the fourth-trimester concept into clinical recommendations and healthcare policies.


Este documento resume la evidencia que existe entre los resultados adversos del embarazo (RAE), tales como son los trastornos hipertensivos, el parto pretérmino, la diabetes gestacional, los defectos en el crecimiento fetal (feto pequeño para la edad gestacional y/o restricción del crecimiento), el desprendimiento de placenta y la pérdida fetal, y el riesgo que tiene una persona gestante de desarrollar factores de riesgo vascular (RV) que pueden terminar provocando enfermedad vascular (EV) futura: cardiopatía coronaria, accidente cerebrovascular, enfermedad vascular periférica e insuficiencia cardíaca. Asimismo, este documento destaca la importancia de saber reconocer los RAE cuando se evalúa el RV en mujeres. Un antecedente de RAE es un indicador suficiente para hacer una prevención primaria de EV. De hecho, adoptar una dieta saludable y aumentar la actividad física entre las mujeres con RAE, de inicio en el embarazo y/o postparto y manteniéndolo a lo largo de la vida, son intervenciones importantes que permiten disminuir el RV. Por otro lado, la lactancia materna también puede disminuir el RV posterior de la mujer, incluyendo menos riesgo de mortalidad. Estudios futuros que evalúen el uso del ácido acetilsalicílico, las estatinas y la metformina, entre otros, en las mujeres con antecedentes de RAE podrían reforzar las recomendaciones sobre el uso de la farmacoterapia en la prevención primaria de la EV entre estas pacientes. Existen diferentes opciones dentro de los sistemas de salud para mejorar la transición de la atención de las mujeres con RAE entre los diferentes profesionales e implementar estrategias para reducir su RV a largo plazo. Una posible estrategia podría ser la incorporación del concepto del cuarto trimestre en las recomendaciones clínicas y las políticas de atención de la salud.

RESUMEN

BACKGROUND: Chronic kidney disease entails a high disease burden that is progressively increasing due to population aging. However, evidence on the effect of the Mediterranean diet on renal function is limited, in particular among older adults in Mediterranean countries. METHODS: Prospective cohort study with 975 community-dwelling adults aged ≥ 60 recruited during 2008-2010 in Spain and followed up to 2015. At baseline, food consumption was obtained using a validated dietary history. Two Mediterranean dietary patterns were used: (i) An a priori-defined pattern, the Mediterranean Diet Adherence Screener (MEDAS score: low adherence: 0-5 points; moderate: 6-8 points; high: 9-14 points); (ii) An a posteriori Mediterranean-like dietary pattern, based on 36 food groups, which was generated using factor analysis. Renal function decline was calculated as an estimated glomerular filtration rate (eGFR) decrease ≥1 mL/min/1.73 m2 per year of follow-up. RESULTS: A total of 104 cases of renal function decline occurred. Compared with participants with a low MEDAS adherence, the multivariable-adjusted odds ratios (95% confident interval) for renal function decline risk were 0.63 (0.38-1.03) for moderate adherence, and 0.52 (0.29-0.95) for high adherence (p-trend: 0.015). Multivariable-adjusted odds ratios (95% confidence interval) for renal function decline risk according to increasing quartiles of the adherence to the a posteriori Mediterranean-like dietary pattern were 1.00, 0.67 (0.38-1.20), 0.65 (0.35-1.19), and 0.47 (0.23-0.96) (p-trend: 0.042). CONCLUSION: A higher adherence to a Mediterranean diet was associated with a lower risk of renal function decline in older adults, suggesting benefits to health of this dietary pattern in Mediterranean countries.
