Project description:Background Self-monitoring of blood pressure (SMBP) improves blood pressure (BP) outcomes at 12-months, but information is lacking on how SMBP affects hypertension care processes and longer-term BP outcomes. Methods and Results We pooled individual participant data from 4 randomized clinical trials of SMBP in the United Kingdom (combined n=2590) with varying intensities of support. Multivariable random effects regression was used to estimate the probability of antihypertensive intensification at 12 months for usual care versus SMBP. Using these data, we simulated 5-year BP control rates using a validated mathematical model. Trial participants were mostly older adults (mean age 66.6 years, SD 9.5), male (53.9%), and predominantly white (95.6%); mean baseline BP was 151.8/85.0 mm Hg. Compared with usual care, the likelihood of antihypertensive intensification increased with both SMBP with feedback to patient or provider alone (odds ratio 1.8, 95% CI 1.2-2.6) and with telemonitoring or self-management (3.3, 2.5-4.2). Over 5 years, we estimated 33.4% BP control (<140/90 mm Hg) with usual care (95% uncertainty interval 27.7%-39.4%). One year of SMBP with feedback to patient or provider alone achieved 33.9% (28.3%-40.3%) BP control and SMBP with telemonitoring or self-management 39.0% (33.1%-45.2%) over 5 years. If SMBP interventions and associated BP control processes were extended to 5 years, BP control increased to 52.4% (45.4%-59.8 %) and 72.1% (66.5%-77.6%), respectively. Conclusions One year of SMBP plus telemonitoring or self-management increases the likelihood of antihypertensive intensification and could improve BP control rates at 5 years; continuing SMBP for 5 years could further improve BP control.

Project description:BackgroundElevated blood pressure (BP) is closely related to stroke and its subtypes. However, different time periods changes in BP may result in differential risk of stroke.HypothesisShort-term blood pressure changes have a more strong impact on stroke and its subtypes than long-term blood pressure changes.MethodsWe designed the study on the effects of short- (2008-2010) and long-term (2004-2010) BP changes on stroke events (2011-2017), including 22?842 and 28?456 subjects, respectively. The difference in ? coefficients between short- and long-term BP changes on the effects of stroke were examined using the Fisher Z test.ResultsDuring a median 12.5-year follow-up period, 1014 and 1505 strokes occurred in short- and long-term groups. In short-term group, going from prehypertension to hypertension, the risk of stroke events increased (stroke: hazard ratio [HR] = 1.537 [1.248-1.894], ischemic stroke: 1.456 [1.134-1.870] and hemorrhagic stroke: 1.630 [1.099-2.415]); going from hypertension to prehypertension, the risk of stroke events decreased (stroke:0.757 [0.619-0.927] and hemorrhagic stroke:0.569 [0.388-0.835]). Similarly, in long-term group, going from prehypertension to hypertension, individuals had an increased risk of stroke (1.291, 1.062-1.569) and hemorrhagic stroke (1.818, 1.261-2.623); going from hypertension to prehypertension, participants had a decreased risk of stroke (0.825, 0.707-0.963) and hemorrhagic stroke (0.777, 0.575-0.949). Furthermore, the effects of BP changes during short-term period on stroke events were greater than that in long-term period.ConclusionsShort- and long-terms BP changes were both associated with the risk of stroke events. Furthermore, short-term BP changes had a stronger impact than did long-term changes on risk of stroke events.

Project description:Purpose:To investigate the short-term effect of self-selected training intensity (SSTI) on ambulatory blood pressure (BP) in hypertensive older women. Participants and Methods:This is a randomized, single-blind, two-arm, parallel-group controlled trial that included 40 medicated hypertensive older women (64.4±3.6 years; resting systolic 118±19 and diastolic BP 68±9 mmHg). SSTI intervention was performed three times per week, 30-50 minutes per session (n=20). The control group participated in health education meetings once per week (n=20). Ambulatory BP (primary outcome) and six-minute walking test performance (secondary outcome) were assessed at baseline and following 8 weeks of intervention. Heart rate (HR), rating of perceived exertion (RPE, 6-20), and affective valence (ie, feeling scale, -5/+5) were recorded during all SSTI sessions. Intention-to-treat and per-protocol analyses were used for data analyses. Results:Fifteen participants from the SSTI group and 17 from the control group completed the study. No differences in ambulatory BP (24-h, awake, and asleep) were observed between SSTI and control groups (intention-to-treat and per-protocol analyses; p>0.05). The SSTI group showed a greater six-minute walking test performance than the control group in the intention-to-treat and per-protocol analyses (p<0.05). The participants exercised at 52±10% of HR reserve reported an RPE of 11±1 and an affective valence of 3.4±1.1 over the 8-week period. Conclusion:SSTI is a feasible approach to induce a more active lifestyle and increase health-related fitness in hypertensive older women, although it does not improve BP control over a short-term period.

Project description:BackgroundFew studies compared the effects of BP changes in short- and long-terms on all-cause mortality and CVD mortality.MethodsWe performed a 12.5-year follow-up study to examine the association between short- (2008 to 2010) and long-term [baseline (2004-2006) to 2010] BP changes and the risk of mortality (2010 to 2017) in the Fuxin prospective cohort study. The Cox proportional hazards model was used for this study, and the average BP was stratified according to the Seven Joint National Committee (JNC7).ResultsWe identified 1496 (805 CVD deaths) and 2138 deaths (1222 CVD deaths) in short- and long-term study. Compared with BP maintainer, in short-term BP changes, for participants from normotension or prehypertension to hypertension, the hazards ratios (HRs) and 95% confidence intervals (CIs) of all-cause mortality were 1.948 (1.118-3.392) and 1.439 (1.218-1.700), respectively, while for participants from hypertension to prehypertension, the HRs (95% CIs) were 0.766 (0.638-0.899) for all-cause mortality and 0.729 (0.585-0.908) for CVD mortality, respectively. In long-term BP changes, for participants from normotension or prehypertension to hypertension, the HRs (95% CIs) of all-cause mortality were 1.738 (1.099-2.749) and 1.203 (1.023-1.414), and they were 2.351 (1.049-5.269) and 1.323 (1.047-1.672) for CVD mortality, respectively. In addition, the effects of short-term BP changes on all-cause and CVD mortality, measured as regression coefficients (?), were significantly greater than those in long-term change (all P<0.05).ConclusionsOur study emphasizes that short-term changes in BP have a greater impact on all-cause and CVD mortality than long-term changes and assess the cut-off value of the changes in blood pressure elevation.

Project description:The authors aimed to assess the reproducibility of normotension and white-coat, masked, and sustained hypertension in 839 untreated patients who underwent two separate assessments (median, 3; interquartile range, 0-13 months) by both office and ambulatory blood pressure (BP) monitoring (ABPM). The proportion of patients falling into the same category in the two assessments was: 52% normotension and 55% white-coat, 47% masked, and 82% sustained hypertension. The most frequent switch was to sustained hypertension (26% of white-coat and 33% of masked hypertension). No clinical factors predicted the change in category, except for higher office diastolic BP in patients with masked hypertension who developed sustained hypertension, compared with those who remained with masked hypertension (84±4 mm Hg vs 80±5 mm Hg; P=.006). The reproducibility of hypertension phenotypes was highly dependent on the time between assessments. The authors conclude that white-coat and masked hypertension phenotypes are only reproducible in the short-term, while they frequently shift towards sustained hypertension in the long-term.

Project description:PURPOSE:This randomized clinical trial compared a personally tailored, automated telephone symptom management intervention to improve self-management among long-term survivors of prostate cancer with usual care enhanced with a nontailored newsletter about symptom management. We hypothesized that intervention-group participants would have more confident symptom self-management and reduced symptom burden. METHODS:A total of 556 prostate cancer survivors who, more than 1 year after treatment, were experiencing symptom burden were recruited from April 2015 to February 2017 across four Veterans Affairs sites. Participants were randomly assigned to intervention (n = 278) or usual care (n = 278) groups. We compared differences in the primary (symptom burden according to Expanded Prostate Cancer Index Composite-26 [EPIC], confidence in self-management) and secondary outcomes between groups using intent-to-treat analyses. We compared domain-specific changes in symptom burden from baseline to 5 and 12 months among the intervention group according to the primary symptom focus area (urinary, bowel, sexual, general) of participants. RESULTS:Most of the prostate cancer survivors in this study were married (54.3%), were white (69.2%), were retired (62.4%), and underwent radiation therapy (56.7% v 46.2% who underwent surgery), and the mean age was 67 years. There were no baseline differences in urinary, bowel, sexual, or hormonal domain EPIC scores across groups. We observed higher EPIC scores in the intervention arm in all domain areas at 5 months, though differences were not statistically significant. No differences were found in secondary outcomes; however, coping appraisal was higher (2.8 v 2.6; P = .02) in intervention-arm patients at 5 months. In subgroup analyses, intervention participants reported improvement from baseline at 5 and 12 months in their symptom focus area domains. CONCLUSION:This intervention was well received among veterans who were long-term survivors of prostate cancer. Although overall outcome differences were not observed across groups, the intervention tailored to symptom area of choice may hold promise to improve associated burden.

Project description:The prognostic value of the short-term blood pressure variability (BPV) from the 24-hour ambulatory blood pressure monitoring (ABPM) remains controversial. The present study aimed to investigate the long-term prognostic value of a high BPV in normotensive and hypertensive subjects from a community-based population.A cohort of 624 normotensive and 633 untreated hypertensive Taiwanese participants (overall 669 men, aged 30-79 years) with baseline ABPM and 20-year all-cause and cardiovascular mortality data was drawn from a community-based survey. BPV was assessed by the read-to-read average real variability of the 24-hour diastolic and systolic blood pressure (SBP) (ARVd and ARVs, respectively).In Cox proportional hazards analysis, ARVd predicted cardiovascular mortality independently of office SBP (hazard ratios (HRs) and 95% confidence intervals (CIs) per 1 SD: 1.31 (1.10-1.55), respectively, bivariate analysis), 24-hour SBP (HR: 1.19, 95% CI: 1.00-1.43), and conventional risk factors (age, sex, smoking, total cholesterol, high-density lipoprotein cholesterol, and fasting blood glucose, HR: 1.40, 95% CI: 1.18-1.67). In subjects with hypertension, a high vs. low ARVd (median: 8.8mm Hg) significantly predicted cardiovascular mortality (HR: 2.11, 95% CI: 1.23-3.62 and HR: 2.04, 95% CI: 1.19-3.51, respectively), when the conventional risk factors plus office SBP or 24-hour SBP were accounted for, respectively. Similar but less significant results were obtained with ARVs. A high ARVd or ARVs did not significantly predict cardiovascular mortality in the normotensive subjects.A high short-term BPV is significantly predictive of long-term cardiovascular mortality in untreated hypertensive but not normotensive community-based subjects, independently of office or 24-hour SBP.

Project description:BackgroundSelf-monitoring is reported to have limited efficacy for hypertension management in high-income countries. In this study, we aimed to evaluate the effect of self-monitoring on blood pressure (BP) control in an Iranian population.MethodsA randomized controlled trial was conducted on 196 mild to moderate hypertensive patients in an outpatient cardiovascular clinic. Patients in the intervention group received a wrist self-monitoring device and were educated to measure and document their BP daily during the study period (24 weeks). Patients in the control group received usual care. Three follow-up visits with the physician were scheduled for all patients (weeks 4, 12, and 24), and the investigator assessed adherence to medications after each visit (pill counting). The primary outcome (BP) was compared between groups using repeated-measure analysis of variance.ResultsOne hundred ninety patients completed the study. Systolic BP (144.4±7.4 vs 145.9±6.4mm Hg) and diastolic BP (85.5±6.9 vs. 85.1±7.7mm Hg) were similar between groups at baseline. The trend of BP was not significantly different between groups during the study period. Systolic and diastolic BP decreased significantly in both groups at the first follow-up visit (systolic BP: 132.6 vs. 133.4mm Hg; diastolic BP: 77.4 vs. 77.2mm Hg). In the intervention group, we observed a small continued decrease in diastolic BP up to week 24 BP (P = 0.01). Both groups showed adherence rates >95% during the study period.ConclusionsOur study could not confirm that self-monitoring can improve BP control in patients with frequent medical visits.

Project description:Elevated blood pressure (BP) has been proposed as a possible pathophysiological mechanism linking exposure to ambient air pollution and the increased risk of cardiovascular mortality and morbidity. In this study, we investigated the hourly relationship between ambient air pollutants and BP. BP measurements were extracted from the electronic health record database of the Seoul National University Bundang Hospital from February 2015 to June 2017. A total of 98,577 individual BP measurements were matched to the hourly levels of air pollutants. A generalized additive model was constructed for hour lags of 0-8 of air pollutants adjusting for age, sex, meteorological variables, and time trend. Systolic BP was shown to be significantly lower at 2-4?hours and 3-5?hours after increased levels of SO2 and CO, respectively (0.24?mmHg and 0.26?mmHg for an interquartile range, respectively). In contrast, O3 and NO2 were associated with significantly increased systolic BP at 3-5 lag hours and at 0-2 lag hours, respectively. BP elevation in association with O3 and NO2 was shown to be significantly greater in hypertensive patients than normotensive subjects. Our findings suggest that short-term exposure to air pollution may be associated with elevated BP.

Project description:ObjectivesThis study explored the relationship between self-management and blood pressure (BP) control in China.DesignA cross-sectional study.SettingEight community health centres from four cities in the Northeast (Shenyang), Northwest (Xi'an), Southwest (Chengdu) and South (Changsha) of China.ParticipantsA total of 873 adults with hypertension, including 360 men and 513 women. Hypertension was defined as systolic BP ?140?mm Hg and/or?diastolic BP ?90?mm Hg.Outcome measurementsBP control was the primary outcome variable. This was categorised as good control if individuals with hypertension reduced their BP to <140/90?mm Hg, otherwise, it was categorised as poor control. Secondary outcomes included self-management, defined as: (1) context or condition-specific factors or physical/social environments (eg, age, sex, marital status, education, personal income and health insurance) and (2) process or knowledge/beliefs, self-regulation skills/abilities and social facilitation (eg, treatment, diet, exercise and risk factor management). Data were analysed using logistic regression models using SPSS V.20.ResultsA total of 67.1% (n=586) participants had poor BP control. Limited outpatient care benefits in mainly rural residents (OR 2.26, 95%?CI 1.06 to 4.81) and longer disease duration (OR 1.03, 95%?CI 1.01 to 1.04) were associated with poor BP control. Self-management practices reduced the odds of having poor BP control (OR 0.98, 95%?CI 0.97 to 0.99).ConclusionsThe individual and family self-management theory can serve as an effective theory for understanding the key contexts, processes and outcomes essential for BP control in China. Future research should evaluate the effect of a self-management intervention (eg, self-monitoring, medication adherence, regular and routine doctor visits, and social supports) for BP control in China using a multisite cluster randomised controlled trial. Sex and gender difference, cost and patient-reported outcomes should also be examined.
