- Background: Masked hypertension is associated with cardiovascular disease (CVD). However, previous large studies have not used the same device to measure office and home blood pressure (BP) and adhered to current home BP measurement recommendations of the European Society of Hypertension. We aimed to characterize masked hypertension and explore its relation to manifestations of CVD.Methods: A randomly selected cohort of 5057 participants aged 50–64 years from the Swedish CardioPulmonary BioImage Study (SCAPIS) was evaluated with office and home BP using the semi-automatic Omron M10-IT oscillometric device. Additional analyses included pulse wave velocity (PWV) and coronary artery calcium score (CACS).Results: Of participants, 4122 did not have current antihypertensive treatment, and were thus included in our analyses. Of these, 2634 (63.9%) had sustained normotension, and 172 (4.2%) had masked hypertension. Participants with masked hypertension vs. sustained normotension were more often men (66.9 vs. 46.2%, P < 0.001). Those with masked hypertension had higher mean PWV [9.3 (95% confidence interval, 95% CI 9.1–9.5) vs. 8.3 (95% CI 8.2–8.4) m/s, P < 0.001] and odds ratio for CACS at least 100 [1.65 (95% CI 1.02–2.68), P = 0.040]. These associations were similar in a posthoc analysis of masked hypertension and sustained normotension, matched for age, sex and systolic office BP.Conclusion: Masked hypertension was associated with markers of CVD. This suggests that home BP is a better predictor of risk, even when the recordings are performed with the same measurement device, in a population-based setting with randomized recruitment.

P-selectin and C-reactive protein in relation to home blood pressure and coronary calcification: a SCAPIS substudy
- 2024

Journal article (peer-reviewed)abstract
- Background: Soluble P-selectin (sP-selectin) and high-sensitivity C-reactive protein (hsCRP) have previously been associated with hypertension, but the relation with out-of-office blood pressure (BP) and coronary artery calcification score is unknown. We aimed to examine the relationship between sP-selectin, hsCRP and home BP, as well as coronary artery calcification score and carotid artery plaques.Methods: In the Swedish CArdioPulmonary bioImage Study (SCAPIS), 5057 randomly selected participants were evaluated with office and home BP using the semi-automatic Omron M10-IT device. For this cross-sectional study, participants with sP-selectin <4 standard deviations above mean and hsCRP <5 mg/l, representing low-grade inflammation, were included. Using generalized linear models, these inflammatory markers were evaluated in relation to BP classifications, as well as coronary artery calcification score and carotid artery plaques.Results: Of participants, 4548 were included in the analyses. The median age was 57.2 (53.4–61.2) years, and 775 (17.0%) reported taking medication for hypertension. Participants in the highest quartile of sP-selectin [odds ratio (OR) 1.67, 95% confidence interval (CI) 1.40–1.98, P < 0.001] and hsCRP [OR 2.25, (95% CI 1.89–2.60), P < 0.001] were more likely to have sustained hypertension. Participants in the highest quartile of hsCRP were also more likely to have masked hypertension, OR (95% CI) 2.31 (1.72–3.10), P < 0.001 and carotid artery plaques, OR (95% CI) 1.21 (1.05–1.38), P = 0.007.Conclusion: Increased sP-selectin and hsCRP were independently associated with sustained hypertension. These findings indicate an association between hypertension and platelet activity, as expressed by sP-selectin.

Uromodulin gene variant is associated with type 2 diabetic nephropathy.
- 2011
-
In: Journal of Hypertension. - 1473-5598. ; 29, s. 1731-1734
-
Journal article (peer-reviewed)abstract
- AIMS/HYPOTHESIS: About 35% of individuals with type 2 diabetes develop persistent albuminuria, lose renal function, and are at increased risk for microvascular complications like diabetic nephropathy. Recent genome-wide association studies have identified the uromodulin locus (UMOD), encoding the most common protein in human urine to be associated with hypertension and also with chronic kidney disease (CKD). In the present study we examined the association of the common variant of the uromodulin (UMOD) gene with type 2 diabetic nephropathy and kidney function. METHODS: UMOD variant rs13333226 was genotyped in a case-control material including 4888 unrelated type 2 diabetic individuals (n = 880 with and n = 4008 without nephropathy) from Sweden (Scania Diabetes Registry) using the ABI Real time TaqMan allelic discrimination assay. RESULTS: The G allele of rs13333226 was associated with a decreased risk of nephropathy [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.69-0.91, P = 0.001] after correction for confounding factors like age, sex, body mass index (BMI), blood pressure, kidney function, smoking and duration of diabetes. The same allele was also associated with a better kidney function [estimated glomerular filtration rate (eGFR), β = 0.117, P < 0.0001] and lower systolic blood pressure (β = -0.048, P = 0.013) in the overall study cohort. CONCLUSION/INTERPRETATION: The present study highlights that the common variant of the UMOD gene is protective against diabetic nephropathy susceptibility and also affects kidney function and blood pressure in patients with type 2 diabetes. However, the association with diabetic nephropathy was independent of blood pressure and kidney function.

Renal angioplasty causes a rapid transient increase in inflammatory biomarkers, but reduced levels of interleukin-6 and endothelin-1 1 month after intervention.
- 2007
-
In: Journal of hypertension. - 0263-6352 .- 1473-5598. ; 25:9, s. 1907-14
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To examine prospectively whether inflammatory biomarkers and endothelin (ET)-1 are increased in patients with renal artery stenosis (RAS), and to investigate how treatment with percutaneous transluminal renal angioplasty (PTRA) affects these variables during the first month after intervention. METHODS: One hundred patients with suspected RAS undergoing renal angiography were included. PTRA was performed if the trans-stenotic mean arterial pressure gradient was>or=10 mmHg. High-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNFalpha), neopterin, CD40 ligand (CD40L) and endothelin-1 (ET-1) were measured before, and 1 day and 1 month after PTRA (n=61) or diagnostic angiography only (n=39). RESULTS: At baseline there were no significant differences in inflammatory biomarkers or ET-1 levels between patients subsequently undergoing PTRA or angiography only. After angiography, IL-6 and hs-CRP had increased in both groups compared to baseline (P<0.001). At this time point hs-CRP (10.90+/-1.48 versus 6.37+/-1.61 mg/l; P<0.05) and IL-6 (13.70+/-0.94 versus 13.00+/-0.17 pg/ml; P<0.01) were higher in the PTRA group than in patients subjected to angiography only. One month after PTRA, systolic blood pressure and levels of IL-6 and ET-1 were lower than before intervention (P<0.05), whereas CD40L had increased compared to baseline (P<0.01). CONCLUSION: In patients with RAS, PTRA triggers rapid transient increases in hs-CRP and IL-6; however, 1 month after PTRA, both IL-6 and ET-1 had decreased compared to before intervention, indicating beneficial effects of PTRA on inflammation and the endothelin system.

Journal article (peer-reviewed)abstract
- Hypertension and diabetes are common and are both associated with high cardiovascular morbidity and mortality. We aimed to investigate associations between mortality risk and country of birth among hypertensive individuals in primary care with and without concomitant diabetes, which has not been studied previously. In addition, we aimed to study the corresponding risks of myocardial infarction and ischemic stroke.This observational cohort study of 62557 individuals with hypertension diagnosed 2001-2008 in the Swedish Primary Care Cardiovascular Database assessed mortality by the Swedish Cause of Death Register, and myocardial infarction and ischemic stroke by the National Patient Register. Cox regression models were used to estimate study outcome hazard ratios by country of birth and time updated diabetes status, with adjustments for multiple confounders.During follow-up time without diabetes using Swedish-born as reference, adjusted mortality hazard ratios per country of birth category were Finland: 1.26 (95% confidence interval 1.15-1.38), high-income European countries: 0.84 (0.74-0.95), low-income European countries: 0.84 (0.71-1.00) and non-European countries: 0.65 (0.56-0.76). The corresponding adjusted mortality hazard ratios during follow-up time with diabetes were high-income European countries: 0.78 (0.63-0.98), low-income European countries: 0.74 (0.57-0.96) and non-European countries: 0.56 (0.44-0.71). During follow-up without diabetes, the corresponding adjusted hazard ratio of myocardial infarction was increased for Finland: 1.16 (1.01-1.34), whereas the results for ischemic stroke were inconclusive.In Sweden, hypertensive immigrants (with the exception for Finnish-born) with and without diabetes have a mortality advantage, as compared to Swedish-born.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To increase the proportion of individuals with hypertension obtaining a blood pressure (BP) of less than 140/90mmHg by improving the management of hypertension in daily life from a person-centred perspective. METHODS: In this unblinded randomized controlled trial, we tested an interactive web-based self-management system for hypertension. A total of 949 patients with hypertension from 31 primary healthcare centres (PHCCs) in Sweden were randomized 1:1 to either the intervention or usual care group. The intervention included daily measurement - via the participant's mobile phone - of BP and pulse and reports of well being, symptoms, lifestyle, medication intake and side effects for eight consecutive weeks. It also included reminders and optional motivational messages. The primary outcome was the proportion of participants obtaining BP of less than 140/90mmHg at 8 weeks and 12months. Significance was tested by Pearson's chi 2 -test. RESULTS: A total of 862 patients completed the trial, 442 in the intervention group and 420 in the control group. The primary outcome (BP <140/90mmHg) at 8 weeks was achieved by 48.8% in the intervention group and 39.9% in the control group ( P =0.006). At 12months, 47.1% (intervention) and 41.0% (control group) had a BP less than 140/90mmHg ( P =0.071). CONCLUSION: The proportion of participants with a controlled BP of less than 140/90mmHg increased after using the interactive system for self-management of hypertension for 8 weeks compared with usual care. Although the trend continued, there was no significant difference after 12months. The results indicate that the effect of the intervention is significant, but the long-term effect is uncertain. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov (NCT03554382).

PERSON-CENTREDNESS IN HYPERTENSION MANAGEMENT USING INFORMATION TECHNOLOGY (PERHIT) : A RANDOMISED CONTROLLED TRIAL IN PRIMARY HEALTH CARE
- 2022

Conference paper (other academic/artistic)abstract
- OBJECTIVE: Few studies address results from use of new technology and patient participation in hypertension management. The PERHIT Study is a multicentre randomised controlled trial with the aim to evaluate the effects of a person-centred approach using a web-based, interactive self-management system through the patient´s own mobile phone on blood-pressure and well-being. Primary aim is the degree of achieved blood pressure (BP) control after eight weeks and one year. In addition, person-centeredness, usefulness, daily life activities in relation to BP values, awareness of risk and health care costs are studied. DESIGN AND METHOD: The PERHIT study was performed in four regions in southern Sweden. Following inclusion, more than 900 patients from 31 primary health care centres were randomised to two groups. In the intervention group (INT), patients were provided with a web-based self-management support system including a home-BP monitor. For eight consecutive weeks, they measured BP and performed self-reports regarding well-being, symptoms, lifestyle, medication intake and side effects every evening via their mobile phone. They could also receive motivational messages and reminders throughout the intervention period. Both patients and professionals had access to graphic feedback of reported values through a secure web portal. Patients in the control (CON) group received standard treatment as usual. RESULTS: The primary outcome (BP < 140/90 mmHg) was achieved by 48.5% and 47.1% in the INT, and by 40.4% and 40.9% in the CON group after 8 weeks (p = 0.016) and 12 months (p = 0.067), respectively. Both patients and professionals experienced the system as a useful resource for communication regarding BP and lifestyle. They described that it could be used to support a constructive and person-centred partnership between patients and professionals. CONCLUSIONS: Blood pressure control was significantly better after eight weeks, but not after one year, following an intervention based on use of mobile phones, feedback and interaction between patients and primary care professionals compared to standard care. The system can be a tool toward a new way of working and help patients reach a controlled BP and play a role in a more person-centred and individually adapted hypertension management.
