Artificial Intelligence-Derived Risk Prediction: A Novel Risk Calculator Using Office and Ambulatory Blood Pressure.

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.

Prognostic Relevance of Short-Term Blood Pressure Variability. The Spanish ABPM Registry.

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.

A blunted nocturnal blood pressure decline is associated with all-cause and cardiovascular mortality.

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.

Impact of timing of antihypertensive treatment on mortality: an observational study from the Spanish Ambulatory Blood Pressure Monitoring Registry.

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.

Ventana de oportunidad: prevención del riesgo vascular en la mujer. Resultados adversos del embarazo y riesgo de enfermedad vascular.] / Consensus document of the Spanish Society of Obstetrics and Gynecology (SEGO) and the Spanish Interdisciplinary Committee for Vascular Prevention (CEIPV). Opportunity window: vascular risk prevention in women. Adverse pregnancy outcomes and risk of vascular disease.

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.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention.

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.

Relationship between clinic and ambulatory blood pressure and mortality: an observational cohort study in 59 124 patients.

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.

Non-dipping blood pressure pattern in pediatricians during on-duty.

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.

Role of ambulatory blood pressure on prediction of cardiovascular disease. A cohort study.

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.

Cooking methods are associated with inflammatory factors, renal function, and other hormones and nutritional biomarkers in older adults.

Evidence of the role of cooking methods on inflammation and metabolic health is scarce due to the paucity of large-size studies. Our aim was to evaluate the association of cooking methods with inflammatory markers, renal function, and other hormones and nutritional biomarkers in a general population of older adults. In a cross sectional analysis with 2467 individuals aged ≥ 65, dietary and cooking information was collected using a validated face-to-face dietary history. Eight cooking methods were considered: raw, boiling, roasting, pan-frying, frying, toasting, sautéing, and stewing. Biomarkers were analyzed in a central laboratory following standard procedures. Marginal effects from generalized linear models were calculated and percentage differences (PD) of the multivariable-adjusted means of biomarkers between extreme sex-specific quintiles (Q) of cooking methods consumption were computed ([Q5 - Q1/Q1] × 100). Participants' mean age was 71.6 years (53% women). Significant PD for the highest vs lowest quintile of raw food consumption was - 54.7% for high sensitivity-C reactive protein (hs-CRP), - 11.9% for neutrophils, - 11.9% for Growth Differentiation Factor-15, - 25.0% for Interleukin-6 (IL-6), - 12.3% for urinary albumin, and - 10.3% for uric acid. PD for boiling were - 17.8% for hs-CRP, - 12.4% for urinary albumin, and - 11.3% for thyroid-stimulating hormone. Concerning pan-frying, the PD was - 23.2% for hs-CRP, - 11.5% for IL-6, - 16.3% for urinary albumin and 10.9% for serum vitamin D. For frying, the PD was a 25.7% for hs-CRP, and - 12.6% for vitamin D. For toasting, corresponding figures were - 21.4% for hs-CRP, - 11.1% for IL-6 and 10.6% for vitamin D. For stewing, the PD was 13.3% for hs-CRP. Raw, boiling, pan-frying, and toasting were associated with healthy profiles as for inflammatory markers, renal function, thyroid hormones, and serum vitamin D. On the contrary, frying and, to a less extent, stewing showed unhealthier profiles. Cooking methods not including added fats where healthier than those with added fats heated at high temperatures or during longer periods of time.

The Mediterranean Diet Protects Renal Function in Older Adults: A Prospective Cohort Study.

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.

Presentamos la adaptación española de las Guías Europeas de Prevención Cardiovascular 2021. En esta actualización además del abordaje individual, se pone mucho más énfasis en las políticas sanitarias como estrategia de prevención poblacional. Se recomienda el cálculo del riesgo vascular de manera sistemática a todas las personas adultas con algún factor de riesgo vascular. Los objetivos terapéuticos para el colesterol LDL, la presión arterial y la glucemia no han cambiado respecto a las anteriores guías, pero se recomienda alcanzar estos objetivos de forma escalonada (etapas 1 y 2). Se recomienda llegar siempre hasta la etapa 2, y la intensificación del tratamiento dependerá del riesgo a los 10 años y de por vida, del beneficio del tratamiento, de las comorbilidades, de la fragilidad y de las preferencias de los pacientes. Las guías presentan por primera vez un nuevo modelo para calcular el riesgo (SCORE2 y SCORE2 OP) de morbimortalidad vascular en los próximos 10 años (infarto de miocardio, ictus y mortalidad vascular) en hombres y mujeres entre 40 y 89 años. Otra de las novedades sustanciales es el establecimiento de diferentes umbrales de riesgo dependiendo de la edad (<50, 50-69, >70 años). Se presentan diferentes algoritmos de cálculo del riesgo vascular y tratamiento de los factores de riesgo vascular para personas aparentemente sanas, pacientes con diabetes y pacientes con enfermedad vascular aterosclerótica. Los pacientes con enfermedad renal crónica se considerarán de riesgo alto o muy alto según la tasa del filtrado glomerular y el cociente albúmina/creatinina. Se incluyen innovaciones en las recomendaciones sobre los estilos de vida, adaptadas a las recomendaciones del Ministerio de Sanidad, así como aspectos novedosos relacionados con el control de los lípidos, la presión arterial, la diabetes y la insuficiencia renal crónica.

Antihypertensive therapy and short-term blood pressure variability.

BACKGROUND AND AIM: Blood pressure variability (BPV) is recognized as a prognostic contributor in hypertension. We aimed to assess differences in short-term BPV in treated hypertensive patients depending on the number, classes, combinations and individual compounds of the antihypertensive treatment. METHODS: We selected 38 188 treated patients from the Spanish Ambulatory BP Monitoring (ABPM) Registry. SBP and DBP standard deviations (SD) from 24-h, daytime and night-time, weighted SD (WSD), and average real variability (ARV) were calculated through ABPM. They were compared (after adjustment for clinical confounders and BP) depending on the number of antihypertensive drugs, antihypertensive drug classes and compounds (in 13 765 patients on monotherapy), or combinations (in 12 716 patients treated with two drugs and 7888 treated with three drugs). RESULTS: Systolic and diastolic BPV significantly increased in patients treated with multiple drugs with respect to monotherapy. Among drug classes, calcium channel blockers, especially amlodipine, and diuretics were associated with lower systolic BPV, including daytime and night-time SD, WSD and ARV, compared with beta blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers. Likewise, in patients treated with two-drug and three-drug combinations, those which included a calcium channel blocker showed lower BPV in comparison to those without such drug class. CONCLUSION: Treatment with calcium channel blockers, especially amlodipine, and with diuretics is associated with slight, but significant lower values of short-term BPV in comparison to other major drug classes, both in monotherapy and in combination. These results could be helpful when considering BPV reduction as an additional treatment target.

Association of clinic and ambulatory heart rate parameters with mortality in hypertension.

OBJECTIVES: Resting heart rate (HR) taken in the office has been shown to be associated with cardiovascular outcomes in the general population, hypertension and heart failure. It is unknown whether 24-h oscillographic pulse rate measurement as an approximation of HR derived from ambulatory blood pressure monitoring (ABPM) associates with cardiovascular outcomes in hypertensive patients. METHODS: We evaluated ABPM recordings from 56 901 patients with complete 3373 421 HR measures entering the final analysis from the Spanish Blood Pressure Monitoring Registry for a median follow-up time of 5.1 years. We explored the association of office HR, mean 24-h HR, mean day HR, mean night HR as well as day-night HR differences, morning mean HR, morning HR surge and night peak HR to all-cause death, cardiovascular death and noncardiovascular death. Data were analyzed by Cox regression analysis, analysis of variance and chi-square test. RESULTS: The Spanish ABPM Registry recorded data in 223 primary care centers in Spain from 2004 until 31 December 2014 at the end of recruitment. Office HR was 3.5 bpm higher than mean 24-h HR, office mean HR versus mean night was 10.4 bpm higher and mean day versus mean night HR 9.3 bpm higher, while there were no relevant difference between office and mean day HR. Office mean, 24-h day and night HR more than 90 bpm were associated with an increased risk for all-cause and noncardiovascular death, whereas for cardiovascular death only mean night HR was predictive. The strongest association to all-cause death was observed with mean night HR [hazard ratio 3.80 (2.87-5.03)], mean 24-h HR [2.85 (2.30-3.54)] and mean day HR [2.22 (1.83-2.70)]. Day-night dipping of more than 8 bpm was associated with a 20% lesser risk on all-cause, cardiovascular and noncardiovascular death. Results were robust after adjusting for relevant risk indicators. CONCLUSION: HR parameters derived from ABPM provide important information, in particular association with death by mean night HR, mean 24-h HR and reduced day-night HR dipping less than 8 bpm superior to office HR.

Prevalence of office and ambulatory hypotension in treated hypertensive patients with coronary disease.

Patients with coronary heart disease (CHD) can be particularly susceptible to the adverse effects of excessive blood pressure (BP) lowering by antihypertensive treatment. The identification of hypotension is thus especially important. This study estimated the prevalence of hypotension among CHD-treated hypertensive patients undergoing ambulatory blood pressure monitoring (ABPM) in routine clinical practice. We performed a cross-sectional study with 2892 CHD-treated hypertensive patients from the Spanish ABPM Registry. Based on previous studies, hypotension was defined as systolic/diastolic BP < 120 and/or 70 mmHg according to office measurements, <115 and/or 65 mmHg according to daytime ABPM, <100 and/or 50 mmHg according to nighttime ABPM, and <110 and/or 60 mmHg according to 24 h ABPM. The participants' mean age was 67.1 years (69.8% men). A total of 19.6% of the patients had office hypotension, 26.5% had daytime hypotension, 9.0% had nighttime hypotension, and 16.1% had 24-hr ABPM hypotension. Low diastolic BP values were responsible for most cases of hypotension. Fifty-eight percent of the cases of hypotension detected by daytime ABPM did not correspond to hypotension according to office BP. The variables independently associated with daytime ambulatory systolic/diastolic hypotension and diastolic hypotension (the latter being the most frequent type of ambulatory hypotension) were age, female sex, and the number of antihypertensive medications. In conclusion, in a large ABPM registry, one out of every four CHD-treated hypertensive patients was potentially at risk because of hypotension according to daytime ABPM, and more than half of them were not identified if office BP was relied on alone. We suggest that ABPM should be performed in these patients.

How do ultrafine particles in urban air affect ambulatory blood pressure?

INTRODUCTION: Air in urban areas is usually contaminated with particle matter. High concentrations lead to a rise in the risk of cardiovascular and respiratory diseases. Some studies have reported that ultrafine particles (UFP) play a greater role in cardiovascular diseases than other particle matter, particularly regarding hypertensive crises and DBP, although in the latter such effects were described concerning clinical blood pressure (BP). In this study, we evaluate the relationship between 24-h ambulatory BP monitoring (ABPM) and atmospheric UFP concentrations in Barcelona. METHODS: An observational study of individual patients' temporal and geographical characteristics attended in Primary Care Centres and Hypertensive Units during 2009-2014 was performed. RESULTS: The participants were 521 hypertensive patients, mean age 56.8 years (SD 14.5), 52.4% were women. Mean BMI was 28.0 kg/m and the most prominent cardiovascular risk factors were diabetes (N = 66, 12.7%) and smoking (N = 79, 15.2%). We describe UFP effects at short-term and up to 1 week (from lag 0 to 7). For every 10 000 particle/cm UFP increase measured at an urban background site, a corresponding statistically significant increase of 2.7 mmHg [95% confidence interval = (0.5-4.8)] in 24-h DBP with ABPM for the following day was observed (lag 1). CONCLUSION: We have observed that a rise in UFP concentrations during the day prior to ABPM is significantly associated with an increase in 24 h and diurnal DBP. It has been increasingly demonstrated that UFP play a key role in cardiovascular risk factors and, as we have demonstrated, in good BP control.

Prognostic Relevance of Short-Term Blood Pressure Variability: The Spanish ABPM Registry.

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, assessed through ambulatory BP monitoring, with total and cardiovascular mortality in a large cohort of patients with hypertension. We selected 63 910 subjects from the Spanish ABPM Registry from 2004 to 2014, with a median follow-up of 4.7 years. Systolic and diastolic BP SD from 24 hours, daytime, and nighttime, weighted SD (mean of daytime and nighttime SD weighted for period duration), average real variability (mean of differences between consecutive readings), variation independent of the mean, and BP variability ratio (ratio between systolic and diastolic 24-hour SD) were calculated through 24-hour ambulatory BP monitoring performed at baseline. Association with total and cardiovascular mortality (obtained through death certificates) were assessed by Cox regression models adjusted for clinical confounders and BP. Patients who died during follow-up had higher values of BP variability compared with those remaining alive. In fully adjusted models, daytime, nighttime, and weighted SD, systolic and diastolic, as well as diastolic average real variability, were all significantly associated with total and cardiovascular mortality. Hazard ratios for 1 SD increase ranged from 1.05 to 1.09 for total mortality and from 1.07 to 1.12 for cardiovascular mortality. A nighttime systolic SD ≥12 mm Hg was independently associated with total (hazard ratio: 1.13 [95% CI, 1.06-1.21]) and cardiovascular mortality (hazard ratio: 1.21 [95% CI, 1.09-1.36]). We conclude that short-term BP variability is independently associated with total and cardiovascular mortality in patients with hypertension.
