- Twenty-four-hour central (Aortic) systolic blood pressure reference values and dipping patterns in untreated individuals
2022-01-09 Central (aortic) systolic blood pressure (cSBP) is the pressure seen by the heart, the brain, and the kidneys. If properly measured, cSBP is closer associated with hypertension-mediated organ damage and prognosis, as compared with brachial SBP (bSBP). We investigated 24-hour profiles of bSBP and cSBP, measured simultaneously using Mobilograph devices, in 2423 untreated adults (1275 women; age, 18–94 years), free from overt cardiovascular disease, aiming to develop reference values and to analyze daytime-nighttime variability. Central SBP was assessed, using brachial waveforms, calibrated with mean arterial pressure (MAP)/diastolic BP (cSBPMAP/DBPcal), or bSBP/diastolic blood pressure (cSBPSBP/DBPcal), and a validated transfer function, resulting in 144 509 valid brachial and 130 804 valid central measurements. Averaged 24-hour, daytime, and nighttime brachial BP across all individuals was 124/79, 126/81, and 116/72 mm Hg, respectively. Averaged 24-hour, daytime, and nighttime values for cSBPMAP/DBPcal were 128, 128, and 125 mm Hg and 115, 117, and 107 mm Hg for cSBPSBP/DBPcal, respectively. We pragmatically propose as upper normal limit for 24-hour cSBPMAP/DBPcal 135 mm Hg and for 24-hour cSBPSBP/DBPcal 120 mm Hg. bSBP dipping (nighttimedaytime/ daytime SBP) was −10.6 % in young participants and decreased with increasing age. Central SBPSBP/DBPcal dipping was less pronounced (−8.7% in young participants). In contrast, cSBPMAP/DBPcal dipping was completely absent in the youngest age group and less pronounced in all other participants. These data may serve for comparison in various diseases and have potential implications for refining hypertension diagnosis and management. The different dipping behavior of bSBP versus cSBP requires further investigation.
- The impact of a web-based lifestyle educational program ('Living better') reintervention on hypertensive overweight or obese patients
2022-05-27 ‘Living Better’, a self-administered web-based intervention, designed to facilitate lifestyle changes, has already shown positive short- and medium-term health benefits in patients with an obesity–hypertension phenotype. The objectives of this study were: (1) to examine the long-term (3-year) evolution of a group of hypertensive overweight or obese patients who had already followed the ‘Living Better’ program; (2) to analyze the effects of completing this program a second time (reintervention) during the COVID-19 pandemic. A quasi-experimental design was used. We recruited 29 individuals from the 105 who had participated in our first study. We assessed and compared their systolic and diastolic blood pressure (SBP and DBP), body mass index (BMI), eating behavior, and physical activity (PA) level (reported as METs-min/week), at Time 0 (first intervention follow-up), Time 1 (before the reintervention), and Time 2 (post-reintervention). Our results showed significant improvements between Time 1 and Time 2 in SBP (4.7 (8.7 to 0.7); p = 0.017), DBP (3.5 (6.2 to 0.8); p = 0.009), BMI (0.7 (1.0 to 0.4); p < 0.001), emotional eating (2.8 (5.1 to 0.5); p = 0.012), external eating (1.1 (2.1 to 0.1); p = 0.039), and PA (Time 1: 2308 2266; Time 2: 3203 3314; p = 0.030, Z = 2.17). Statistical analysis showed no significant differences in SPB, DBP, BMI, and eating behavior between Time 0 and Time 1 (p > 0.24). Implementation of the ‘Living Better’ program maintained positive long-term (3-year) health benefits in patients with an obesity–hypertension phenotype. Moreover, a reintervention with this program during the COVID-19 pandemic produced significant improvements in blood pressure, BMI, eating behavior, and PA.
- May Measurement Month 2019 : an analysis of blood pressure screening results from Spain
2021-05-20 The aim of the May Measurement Month (MMM) is devoted to better understanding the awareness, treatment, and control rates of hypertension in Spain. Presented here are the data corresponding to 2019 campaign. In 2019, a total of 4433 patients (61.5% males) with a mean age of 54.8 years were included. Of all, 96.0% were Caucasian, and 3294 were recruited in pharmacies. The mean values of systolic blood pressure (BP) were 125.6 and of diastolic 76.7mmHg in the whole population. The most recent previous BP measurement took place more than 1 year before in 27.6% of participants. A total of 1883 were hypertensive (systolic BP 140 mmHg or diastolic BP 90mmHg or taking antihypertensive medication), of whom 77.2%/were aware and 71.1% were onmedication. Of all, 64.9% of those on medication and 46.1% of all hypertensive participants had a BP controlled to <140/90mmHg. These data from MMM 2019 continue to indicate the need for an improvement in the awareness, treatment, and control of hypertension in Spain.
- Association of hypertension with all-cause mortality among hospitalized patients with COVID-19
2020-09-28 It is unclear to which extent the higher mortality associated with hypertension in the coronavirus disease (COVID-19) is due to its increased prevalence among older patients or to specific mechanisms. Cross-sectional, observational, retrospective multicenter study, analyzing 12226 patients who required hospital admission in 150 Spanish centers included in the nationwide SEMI-COVID-19 Network. We compared the clinical characteristics of survivors versus non-survivors. The mean age of the study population was 67.5 16.1 years, 42.6% were women. Overall, 2630 (21.5%) subjects died. The most common comorbidity was hypertension (50.9%) followed by diabetes (19.1%), and atrial fibrillation (11.2%). Multivariate analysis showed that after adjusting for gender (males, OR: 1.5, p=0.0001), age tertiles (second and third tertiles, OR: 2.0 and 4.7, p=0.0001), and Charlson Comorbidity Index scores (second and third tertiles, OR: 4.7 and 8.1, p = 0.0001), hypertension was significantly predictive of all-cause mortality when this comorbidity was treated with angiotensin-converting enzyme inhibitors (ACEIs) (OR: 1.6, p = 0.002) or other than renin-angiotensin-aldosterone blockers (OR: 1.3, p = 0.001) or angiotensin II receptor blockers (ARBs) (OR: 1.2, p = 0.035). The preexisting condition of hypertension had an independent prognostic value for all-cause mortality in patients with COVID-19 who required hospitalization. ARBs showed a lower risk of lethality in hypertensive patients than other antihypertensive drugs.
- May Measurement Month 2018 : an analysis of blood pressure screening results from Spain
2020-08-28 Elevated blood pressure (BP) is the single most important contributing risk factor to the global disease burden, leading to over 10 million deaths each year. In Spain, hypertension (HTN) affects around 20% of the adult population and remains the greatest attributable cause of cardiovascular mortality. May Measurement Month (MMM) is a worldwide initiative aimed at increasing awareness of HTN and to improve the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged 18 and over was carried out in May 2018. Blood pressure measurement, the definition of HTN and statistical analysis followed the standard MMM protocol. Anthropometric data and responses to questionnaires on demographic, lifestyle, and environmental factors were obtained as additional information. Screening sites mainly in community pharmacies, universities, primary care centres, HTN units, and cardiovascular departments in hospitals were set up across Spain as part of this initiative. In total, 7646 individuals (63.5% female) were screened during MMM18. After multiple imputation, 40.0% had HTN, of whom 74.4% were aware of their diagnosis and 69.6% were taking antihypertensive medication. Of individuals not receiving antihypertensive medication, 16.9% were hypertensive. Of individuals receiving antihypertensive medication, 36.4% had uncontrolled BP. MMM18 almost doubled the number of participants of MMM17 and was the largest BP screening campaign ever undertaken in Spain, showing that in the absence of systematic screening programmes for HTN, MMM can identify a great number of individuals at risk, increasing their awareness and attracting the interest of the healthcare system in Spain.
- Impact of a Web-based exercise and nutritional education intervention in patients who are obese with hypertension : randomized wait-list controlled trial
2020-04-14 Background: Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviors. These have a tremendous potential for delivering electronic health interventions in scalable and cost-effective ways. There is strong evidence that the use of these programs can lead to weight loss and can lower patients’ average blood pressure (BP) levels. So far, few studies have investigated the effects of internet-based programs on patients who are obese with hypertension (HTN). Objective: The aim of this study is to investigate the short- and long-term efficacy, in terms of body composition and BP parameters, of a self-administered internet-based intervention involving different modules and learning techniques aimed at promoting lifestyle changes (both physical activity and healthy eating) in patients who are obese with HTN. Methods: A randomized wait-list controlled trial design was used. We recruited 105 adults with HTN who were overweight or obese and randomly assigned them to either a 3-month internet-based intervention group (n=55) or the wait-list control group (n=50). We assessed BMI (primary outcome), body fat mass (BFM), systolic (S)BP and diastolic (D)BP, blood glucose and insulin levels, physical activity levels, and functional capacity for aerobic exercise at Time 0 (preintervention) and Time 1 (postintervention). All the patients in the wait-list control group subsequently received the intervention, and a secondary within-group analysis, which also included these participants, was conducted at Time 2 (12-month follow-up). Results: A 2-way mixed analysis of covariance showed a significant decrease in BMI, BFM, and blood glucose at 3 months in the internet-based intervention group; the effect size for the BMI and BFM parameters was moderate to large, and there was also a borderline significant trend for DBP and insulin. These results were either maintained or improved upon at Time 2 and showed significant changes for BMI (mean difference −0.4, 95% CI −0.1 to −0.6; P=.005), BFM (mean difference −2.4, 95% CI −1.1 to −3.6; P<.001), DBP (mean difference −1.8, 95% CI −0.2 to −3.3; P=.03), and blood glucose (mean difference −2, 95% CI 0 to −4; P=.04). Conclusions: Implementation of our self-administered internet-based intervention, which involved different learning techniques aimed to promote lifestyle changes, resulted in positive short- and long-term health benefits in patients who are obese with HTN.
- Analysis of the efficacy of an internet-based self-administered intervention (“Living Better”) to promote healthy habits in a population with obesity and hypertension : an exploratory randomized controlled trial
2019-04-03 Introduction: Changes in unhealthy lifestyles are key elements in the prevention and treatment of obesity and hypertension. Internet-based programs offer great potential for the implementation of evidence-based interventions focused on promoting healthy habits. We evaluate the efficacy of an Internet-based self-administered program (“Living Better”) that addresses people diagnosed as being overweight or having type I obesity and hypertension. Methods: The sample was composed of a total of 106 participants (age Mean = 53; 59 males) from a public hospital in Spain, diagnosed as being overweight or having type I obesity and hypertension and randomized into two groups—the intervention group (IG; Internet-based intervention) and the control group (CG; usual medical treatment). The intervention used cognitive-behavioral strategies and psychoeducation to promote healthy habits. Anthropometric data (i.e., Body Mass Index –BMI-, waist circumference, and hip circumference) and lifestyle/psychological data (i.e., quality of life, physical activity, eating styles, motivation, mood, and self-efficacy) were assessed before and after the intervention, and at 6 and 12-month follow-ups. Results: Significant differences were observed between the IG and the CG in anthropometrical variables after intervention (i.e., BMI and waist circumference), external eating style, and anxiety and stress scores (p < 0.05). Follow-up data showed that changes were maintained in BMI, waist and hip circumference, and external eating in the IG. After receiving the Internet-based treatment, the CG also improved its clinical condition. Discussion: This study demonstrates that the Internet is a viable alternative for the delivery and dissemination of interventions focused on promoting healthy habits, and a totally self-administered intervention can produce long-term positive results.
- Assessment of arterial stiffness by brachial oscillometry in community pharmacies for managing hypertension (COPHARTEN)
2019-12-16 Background and Objective: Arterial Stiffness (AS) measured as pulse wave velocity has emerged in recent years as a hypertension mediated organ damage with independent prognostic value for Cardiovascular (CV) diseases that has also been discussed as a potential cause of Hypertension (HTN). The aim of this study is to (1) evaluate how measurement of AS modifies CV risk calculation by SCORE, (2) to measure the predictive value of AS for incident hypertension in normotensive patients, and (3) to analyze the association between control of HTN and presence of AS in sustained HTN. Patients and Methods: A longitudinal, prospective, observational trial under conditions of daily pharmaceutical and clinical practice will be conducted in approximately 60 community pharmacies of the Iberian Peninsula in normotensive and/or hypertensive patients entering a pharmacy spontaneously. In the first cross-sectional step, AS will be estimated with a semiautomatic, validated device (Mobil-O-Graph®, IEM), followed by a 10-item questionnaire. The patients will be referred to Primary Care for stratifying risk by SCORE tables and standard evaluation. In the second longitudinal step, patients will be asked to repeat the visit after 12 months. Discussion: This study aims to improve CV risk stratification and to investigate the potential of AS in predicting incident HTN in normotensive subjects. Besides, it will analyze the role of arterial stiffness as an associated factor to prevent control in sustained HTN in a setting of cooperation between community pharmacies and physicians in daily clinical practice.
