The role of wearable home blood pressure monitoring in detecting out-of-office control status.

Ambulatory blood pressure (ABP) and home blood pressure (HBP) monitoring is currently recommended for management of hypertension. Nonetheless, traditional HBP protocols could overlook diurnal fluctuations, which could also be linked with adverse cardiovascular outcomes. In this observational study, we studied among a group of treated hypertensive patients (N = 62, age: 52.4 ± 10.4 years) by using out-of-office ABP and wearable HBP. They received one session of 24-h ABP measurement with an oscillometric upper-arm monitor, and totally three sessions of 7-day/6-time-daily wearable HBP measurement separated in each month with HeartGuide. Controlled hypertension is defined as an average BP <130/80 mmHg for both daytime ABP and HBP. There was substantial reliability (intraclass correlation coefficient, ICC 0.883-0.911) and good reproducibility (Cohen's kappa = 0.600) for wearable HBP measurement, especially before breakfast and after dinner. Among all patients, 27.4% had both uncontrolled HBP and ABP, 30.6% had uncontrolled HBP only, while 6.5% had uncontrolled ABP only. Female gender and increased numbers of anti-hypertensive agents are correlated with controlled hypertension. Patients with uncontrolled hypertension had a significantly higher maximal daytime blood pressure, which was previously signified as an imperial marker for cardiovascular risk. In conclusion, wearable HBP monitoring in accordance with a dedicated daily-living schedule results in good reliability and reproducibility. Patients with an uncontrolled wearable HBP should benefit from repeated HBP or ABP measurement for risk stratification.

The levels of both sFlt-1 and PlGF are measured in pg/mL. sFlt-1 soluble fms-like tyrosine kinase-1, PlGF placental growth factor, PPV positive predictive value, NPV negative predictive value.

Standardized home blood pressure monitoring: Rationale behind the 722 protocol.

Home blood pressure (HBP) has been recognized as a prognostic predictor for cardiovascular events, and integrated into the diagnosis and management of hypertension. With increasing accessibility of oscillometric blood pressure devices, HBP monitoring is easy to perform, more likely to obtain reliable estimation of blood pressures, and feasible to document long-term blood pressure variations, compared to office and ambulatory blood pressures. To obtain reliable HBP estimates, a standardized HBP monitoring protocol is essential. A consensus regarding the optimal duration and frequency of HBP monitoring is yet to be established. Based on the current evidence, the "722" protocol, which stands for two measurements on one occasion, two occasions a day (morning and evening), and over a consecutive of 7 days, is most commonly used in clinical studies and recommended in relevant guidelines and consensus documents. HBP monitoring based on the "722" protocol fulfills the minimal requirement of blood pressure measurements to achieve agreement of blood pressure classifications defined by office blood pressures and to predict cardiovascular risks. In the Taiwan HBP consensus, the frequency of repeating the "722" protocol of HBP monitoring according to different scenarios of hypertension management, from every 2 weeks to 3 months, is recommended. It is reasonable to conclude that the "722" protocol for HBP monitoring is clinically justified and can serve as a basis for standardized HBP monitoring.

Increased mortality with intensive control in patients with higher baseline SBP and lower Framingham risk.

OBJECTIVE: In the Systolic Blood Pressure Intervention Trial (SPRINT), the relative reduction in primary outcome with intensive blood pressure (BP) control was numerically smallest in the highest baseline SBP tertile. In this post hoc analysis of SPRINT, the goal was to explore whether the effects of intensive BP treatment varied among patients with different baseline SBP and cardiovascular risks. METHODS: Patient-level data from 9361 randomized participants in SPRINT were used. Heterogeneity between treatment and patient characteristics were examined stratified by different baseline SBP levels. Cumulative incidences of primary outcome and all-cause death were compared between treatment groups for patients with baseline SBP at least 160 mmHg and lower Framingham risk. RESULTS: For participants with a baseline SBP of at least 160 mmHg, intensive treatment was associated with a higher rate of all-cause death as compared with standard treatment (1.86 vs. 1.62% per year). After adjustment for age and sex, intensive treatment was associated with significantly increased all-cause death compared with standard treatment [hazard ratio (95% CI) for intensive group: 3.12 (1.00-9.69); P = 0.049] in participants with an SBP of at least 160 mmHg and a Framingham risk score of 31.3% or less (average of median and geometric mean). Patient outcomes were otherwise similar regarding age, use of antihypertensive therapy, cardiovascular disease or chronic kidney disease. CONCLUSION: Among the SPRINT participants with a baseline SBP of at least 160 mmHg and a lower Framingham risk score, targeting an SBP of less than 120mmHg compared with less than 140mmHg resulted in a significantly higher rate of all-cause death.

May Measurement Month 2019: an analysis of blood pressure screening results from Taiwan.

To bolster the awareness of high blood pressure (BP) and to monitor the trend of hypertension control rate. Similar to May Measurement Month (MMM) 2017 and 2018 campaigns, we conducted the MMM 2019 campaign in 643 community pharmacies across Taiwan, and recruited adults aged 20 years or over in May and June of 2019. After filling in an anonymous questionnaire regarding medical history and lifestyle habits and having 10-min sitting rest, pharmacists took triplicate upper-arm BP readings on participants using an automated oscillometric sphygmomanometer. The means of the second and third BP readings were used as the screening BP estimates. Hypertension was defined if one of the followings was met: use of antihypertensive medications, systolic BP ≥140 mmHg, or diastolic BP ≥90 mmHg. Controlled BP was defined as BP of <140/90 mmHg. Of the 24 851 participants enrolled (mean age, 55.8 ± 15.2 years), 12 427 (50.0%) were women. Among 12 351 (49.7%) participants with hypertension, 10 463 (84.7%) were aware of their high BP, and 10 142 (82.1%) received antihypertensive medications. While 59.2% of all hypertensive participants had controlled BP, the BP control rate was 72.0% in treated hypertensive participants. MMM campaigns offer a feasible way to monitor the trends in both awareness and control of hypertension. This nationwide annual BP screening campaign, from 2017 to 2019, demonstrated continued improvement in hypertension control in Taiwan.

Efficacy and safety of ticagrelor versus clopidogrel in patients with non-ST-elevation myocardial infarction in Taiwan.

The clinical efficacy of ticagrelor versus clopidogrel has not been replicated in East Asian populations. The pronounced bleeding risk with ticagrelor was of concern given the increased bleeding tendency in Asian populations. This study evaluated efficacy and safety of ticagrelor versus clopidogrel in patients with non-ST-elevation myocardial infarction (NSTEMI) in the entire Taiwan. We used the Taiwan National Health Insurance Research Database to identify 6203 patients aged ≥ 20 years with NSTEMI hospitalization and prescription of dual antiplatelets at discharge between January 2014 and December 2014. Cohorts of ticagrelor and clopidogrel were matched 1:1 based on propensity score matching to balance baseline covariates. The primary composite efficacy endpoints included death from any cause, non-fatal myocardial infarction, and non-fatal stroke. The secondary efficacy endpoints were the individual components. The primary safety endpoint was major bleeding requiring hospitalization. The incidence of primary efficacy endpoint was 20.3% in the ticagrelor users and 20.7% in the clopidogrel users (adjusted HR 0.94; 95% CI 0.73-1.22), with the median (interquartile range, IQR) follow-up period of 5.2 (2.3-8.5) months. The incidence of primary safety endpoint was 2.3% in the ticagrelor users and 3.2% in the clopidogrel users (adjusted HR 0.67; 95% CI 0.33-1.35). Regarding the secondary efficacy endpoint, patients treated with ticagrelor had significantly lower incidence of stroke (adjusted HR 0.44; 95% CI 0.21-0.94; p = 0.033). In this nationwide Taiwanese cohort of NSTEMI, treatment with ticagrelor after discharge, as compared to clopidogrel, had similar rates of ischemic composite events and major bleeding. Nevertheless, the median follow-up time was only 5.2 months, and the reduced stroke events with ticagrelor compared to clopidogrel needs further verification.

Variation in Blood Pressure Classification Using 7 Blood Pressure Estimation Protocols Among Adults in Taiwan.

Importance: Discrepancies in blood pressure (BP) estimates lead to incomparable BP assessment. Objective: To determine intraindividual discrepancies in BP estimates and classifications based on different BP estimation protocols. Design, Setting, and Participants: This cross-sectional study was a secondary analysis of data from the May Measurement Month Taiwan in 2017 and 2018, which were cross-sectional survey campaigns at pharmacies nationwide to raise awareness of high BP. Participants were volunteers aged 20 years or older. Analysis was conducted from February 2 to August 7, 2020. Exposure: Pharmacist-measured sitting BP using oscillometric sphygmomanometers. Main Outcomes and Measures: A total of 7 BP estimation protocols were assessed according to the latest American College of Cardiology (ACC), Chinese Hypertension League (CHL), European Society of Cardiology (ESC), International Society of Hypertension, Japanese Society of Hypertension, and National Institute of Health and Care Excellence (NICE) hypertension guidelines, and the proposed Averaging the Lowest Two systolic readings protocol. According to BP classification schemes of ESC and ACC guidelines, intraindividual discrepancies were identified if classification inconsistencies among 7 BP estimates were present. Results: Of 81 041 participants, 62 647 adults with 3 BP readings were included. The median (interquartile range) age was 59.0 (46.0-69.0) years, and 31 922 (51.5%) were women. The intraindividual maximum mean (SD) differences in systolic/diastolic BP estimates among the seven protocols were 4.8 (4.3)/3.3 (3.1) mm Hg. The highest prevalence of BP of 140/90 mm Hg or higher was by CHL (16 405 participants [26.2%]) and the lowest was by Averaging the Lowest Two (13 996 participants [22.3%]; P < .001); while the highest prevalence of 130/80 mm Hg or higher was by NICE (37 232 participants [59.4%]) and the lowest prevalence was by Averaging the Lowest Two (32 788 participants [52.4%]; P < .001). Compared with the other 6 estimates, Averaging the Lowest Two reclassified 7.3% to 15.8% of participants designated as 140/90 mm Hg or higher to less than 140/90 mm Hg, and 4.9% to 14.1% of those as 130/80 mm Hg or higher to less than 130/80 mm Hg. Intraindividual discrepancies in classifications occurred in 19 815 participants (31.6%) with the ESC classification and 16 401 participants (26.2%) with the ACC BP classification. Classification agreements were the lowest between NICE (κ coefficient, 0.667 [95% CI, 0.662-0.671]) and ESC protocols (κ coefficient, 0.705 [95% CI, 0.701-0.709]). Conclusions and Relevance: This cross-sectional study of adults in Taiwan found that different BP estimation protocols led to considerable intraindividual discrepancies in BP estimates and classifications. These findings suggest that the Averaging the Lowest Two protocol is less likely to overestimate BP and could serve as a prudent recommendation for BP estimation.

May Measurement Month 2018: an analysis of blood pressure screening results from Taiwan.

To raise awareness of hypertension in the general population, we have held an annual community-based nationwide campaign for blood pressure (BP) screening. The 2018 May Measurement Month (MMM) campaign in Taiwan followed a similar protocol as the 2017 MMM campaign. We recruited adults aged 20 years and older at about 800 community pharmacies across Taiwan. After a 10-min seated rest, volunteers-consisting of community pharmacists-took three BP readings using automated BP devices. The means of the 2nd and 3rd BP readings were used as the screening BP estimates. Hypertension was defined as current use of antihypertensive medications, or the screening BP of ≥140/90 mmHg. Of the 15 365 enrolled participants with a mean age of 56.8 ± 16.4 years, 53.3% were women. After imputation, we found 48.1% of the individuals had hypertension. Among participants with hypertension, 83.7% were aware, 55.0% had controlled BP, and 81.3% were medically treated, of whom 67.7% had controlled BP (<140/90 mmHg). In contrast to the global results, our results showed that the participants with diabetes mellitus, prior myocardial infarction, or stroke had higher BP than those without these comorbidities. The annual campaign experience enables us to establish a feasible approach to raising awareness and to assessing the management of hypertension in the general population. Whether the regular annual BP screening campaign makes a lasting effect on hypertension-related disease burden awaits verification.

Prevalence, Treatment, Control and Monitoring of Hypertension: A Nationwide Community-Based Survey in Taiwan, 2017.

BACKGROUND: Inadequate awareness and control remain the major obstacles for hypertension management worldwide. This observational study intended to assess the current status of hypertension management in Taiwan. METHODS: The Taiwan May Measurement Month (MMM) campaign was a nationwide survey for public alertness to hypertension initiated in 2017 and conducted in local pharmacies. Participants were asked about body habitus, comorbidities, smoking/drinking, use of anti-hypertensive drugs, and frequency of self-measured blood pressure (SMBP) monitoring. Three blood pressure (BP) readings were then measured by trained pharmacists. The mean BP was obtained by averaging all readings. RESULTS: BP recordings were obtained from 49,522 participants (average age, 56.9 ± 16.0 years), of whom 26.1% had an elevated pharmacist-measured BP (≥ 140/90 mmHg). The rate of BP control, defined as pharmacist-measured BP < 140/90 mmHg at the MMM visit, was 63.1% among treated hypertensive participants (n = 21,410). Participants who had uncontrolled hypertension were associated with a higher body mass index, currently smoking/drinking, diabetes, and stroke. More active SMBP monitoring (≥ weekly) was more often implemented in the participants with advanced age and cardiovascular diseases. More active SMBP (≥ weekly) was associated with lower measured BP among treated hypertensive participants but not overall control rate (control rate: 56.4% for ≥ weekly vs. 55.8% for < weekly, p = 0.363). CONCLUSIONS: In the Taiwan MMM 2017, the hypertension control rate surpassed 60% in treated hypertensive participants. Suboptimal BP control was related to cardiovascular risk factors and prior stroke. Treated hypertensives had a lower measured BP but similar hypertension control rate for more active versus less active SMBP.

May Measurement Month 2017: Results from Taiwan-East Asia.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programs worldwide. Given the consistent 30% unawareness rate across all hypertension surveys in Taiwan, we collaborated with the International Society of Hypertension to launch the MMM campaign. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. Over 1200 community pharmacies joined in this campaign, where participants were recruited to obtain BP measurements using automated oscillometric sphygmomanometers. Triplicate BP readings of right or left brachial artery were obtained after sitting for 10 min. A total of 52 514 individuals were screened during MMM17. After multiple imputation, 28 123 (53.8%) had hypertension. Of individuals not receiving antihypertensive medication, 5226 (17.8%) were hypertensive. Of individuals receiving antihypertensive medication, 8121 (35.7%) had uncontrolled BP. As compared with underweight individuals, adjusted systolic BP and diastolic BP raised by 6.1 and 4.1 mmHg, respectively, in overweight ones; while by 9.4 and 5.6 mmHg, respectively, in obese ones. May Measurement Month(MMM)17 was the largest BP screening campaign undertaken in Taiwan. The substantial numbers of unidentified and uncontrolled hypertensive patients, though lower than prior surveys in Taiwan, are challenging. Whether the continued MMM campaign would raise hypertension awareness at the national level awaits verification.

[Assessing environmental and economical benefits of integrated sewage treatment systems].

Sewage treatment, treated water treatment and sludge treatment are three basic units of an integrated sewage treatment system. This work assessed the influence of reusing or discharge of treated water and sludge landfill or compost on the sustainability of an integrated sewage treatment system using emergy analysis and newly proposed emergy indicators. This system's value included its environmental benefits and the products. Environmental benefits were the differences of the environmental service values before and after sewage treatment. Due to unavailability of data of the exchanged substance and energy in the internal system, products' values were attained by newly proposed substitution values. The results showed that the combination of sewage treatment, treated water reuse and sludge landfill had the strongest competitiveness, while the combination of sewage treatment, treated water reuse and earthworm compost was the most sustainable. Moreover, treated water reuse and earthworm compost were helpful for improving the sustainability of the integrated sewage treatment system. The quality of treated water and local conditions should be also considered when implementing the treated water reuse or discharge. The resources efficiency of earthworm compost unit needed to be further improved. Improved emergy indices were more suitable for integrated sewage treatment systems.
