A 2020 Vision of Hypertension

The effects of education based on the Roy adaptation model on medication adherence and psychosocial adjustment in hypertensive patients

BACKGROUND AND AIM

Patient education utilizing nursing theory can enhance patient adherence to treatment and potentially decrease mortality rates. The objective of this investigation was to assess the impact of Roy's adaptation Model-focused education on medication adherence and psychosocial compliance in hypertensive patients.

METHODS

This study was conducted in N = 60 hypertensive patients (n = 30 control group and n = 30 experimental group) based on a randomized controlled trial design. In the pre-test phase of the study, data was collected using the Patient Information Form, the medication adherence rating scale (MARS), and the psychosocial adjustment to illness scale-self-report (PAIS-SR). After the pre-test phase, the experimental group received hypertension education and the "Hypertension Education Booklet" for a duration of four weeks. No education was provided to the control group patients; only routine follow-ups were conducted. In the post-test phase (after four weeks), both groups were reassessed using MARS and PAIS-SR. After completing the study, the control group patients who volunteered to participate in the education were provided with hypertension education and the "Hypertension Education Booklet" for a duration of four weeks (n = 4).

RESULTS

The post-test measurements of patients in the experimental group (after 4 weeks of education) revealed an increase in the mean MARS scores (6.50 ± 0.86) and a significant decrease in the total and subscale mean scores of PAIS-SR (24.12 ± 7.08) (p < 0.05). No changes were observed in the control group patients.

CONCLUSION

The results of the study revealed that the education based on the Roy's Adaptation Model increased hypertensive individuals' medication adherence and physiological, psychological, and social adjustment to the disease.

RELEVANCE TO CLINICAL PRACTICE

The education based on the Roy's Adaptation Model seems to be effective in increasing patients' adherence to treatment and adjustment to the disease. This model can be used in various diseases and societies, since it increases adjustment to the disease and the effectiveness of treatment.

Sex differences in the applicability of Western cardiovascular disease risk prediction equations in the Asian population

AIMS

Cardiovascular diseases (CVDs) are the most common cause of death, but they can be effectively managed through appropriate prevention and treatment. An important aspect in preventing CVDs is assessing each individual's comprehensive risk profile, for which various risk engines have been developed. The important keys to CVD risk engines are high reliability and accuracy, which show differences in predictability depending on disease status or race. Framingham risk score (FRS) and the atherosclerotic cardiovascular disease risk equations (ASCVD) were applied to the Korean population to assess their suitability.

METHODS

A retrospective cohort study was conducted using National Health Insurance Corporation sample cohort from 2003 to 2015. The enrolled participants over 30 years of age and without CVD followed-up for 10 years. We compared the prediction performance of FRS and ASCVD and calculated the relative importance of each covariate.

RESULTS

The AUCs of FRS (men: 0.750; women: 0.748) were higher than those of ASCVD (men: 0.718; women: 0.727) for both sexes (Delong test P <0.01). Goodness of fits (GOF) were poor for all models (Chi-square P < 0.001), especially, underestimation of the risk was pronounced in women. When the men's coefficients were applied to women's data, AUC (0.748; Delong test P<0.01) and the GOF (chi-square P = 0.746) were notably improved in FRS. Hypertension was found to be the most influential variable for CVD, and this is one of the reasons why FRS, having the highest relative weight to blood pressure, showed better performance.

CONCLUSION

When applying existing tools to Korean women, there was a noticeable underestimation. To accurately predict the risk of CVD, it was more appropriate to use FRS with men's coefficient in women. Moreover, hypertension was found to be a main risk factor for CVD.

Impact of healthy lifestyles on risk of hypertension in the Chinese population: finding from SHUN-CVD study

INTRODUCTION

Lifestyle factors are known to play a role in the development of hypertension. We aimed to study the relationship between lifestyle and hypertension in a Chinese population.

METHODS

This study involved 3,329 participants (1,463 men and 1,866 women) aged 18-96 years in the Shenzhen-Hong Kong United Network on Cardiovascular Disease. A healthy lifestyle score was derived from 5 factors: no smoking, no alcohol consumption, active physical activity, normal body mass index, and a healthy diet. Multiple logistic regression was used to investigate the relationship between lifestyle score and hypertension. The influence of each lifestyle component on hypertension was also assessed.

RESULTS

In the overall population, 950 (28.5%) participants had hypertension. The risk of hypertension decreased with increasing healthy lifestyle scores. Compared with participants with the lowest score (score: 0), the multivariable odds ratios (ORs) and corresponding 95% confidence intervals for participants with scores 3, 4, and 5 were 0.65 (0.41-1.01), 0.62 (0.40-0.97), and 0.37 (0.22-0.61), respectively (P for trend <0.001). After adjusting for age, sex, and diabetes, the score was associated with hypertension risk (P for trend = 0.005). Compared with a lifestyle score of 0, the adjusted OR for hypertension for participants with a score of 5 was 0.46 (0.26-0.80).

CONCLUSIONS

The risk of hypertension is inversely related to the healthy lifestyle score. This reinforces the need to address lifestyle to reduce the risk of hypertension.

Dynamic changes in prevalence of type 2 diabetes along with associated factors in Bangladesh: Evidence from two national cross-sectional surveys (BDHS 2011 and BDHS 2017-18)

BACKGROUND AND AIMS

Prevalence of type 2 diabetes has been rising rapidly especially in low- and middle-income countries. The purpose of this study is to analyze the prevalence of type 2 diabetes in 2011 and 2017-18, and the risk factors based on the Bangladesh Demographic and Health Surveys (BDHS).

METHODS

The study comprised of data from the BDHS 2011 and the BDHS 2017-18 with 7565 (50.6% female) and 12,299 respondents (56.9% female) respectively. The plasma blood glucose was classified into normal, pre-diabetes, and diabetes categories. While univariate analysis was performed to determine the data, Chi-square and gamma analyses were used for bivariate estimation of the correlation between diabetes status and other comorbidities. Multinomial and ordinal logistic regression were also performed to trace the link between diabetes and various risk factors.

RESULTS

The 2011 BDHS survey indicated that nearly half of the participants (47.6%) had pre-diabetic condition, while 10.2% were diagnosed with diabetes. On the other hand, the BDHS 2017-18 demonstrated that 28.6% and 8.6% of participants had pre-diabetes and diabetes, respectively. Results of inferential statistics showed that gender (p<0.05), age, wealth status, physical activity, BMI (p<0.01), and caffeinated beverages (p<0.05), were significantly linked with diabetes status.

CONCLUSION

According to our findings, older people and people with lower education are more likely to develop diabetes. BMI` Physically active, wealth status, diet and lifestyle were significant predictors of type 2 diabetes. Healthy lifestyle, physical activities, proper knowledge and awareness can reduce the risk of T2D.

Mildly elevated diastolic blood pressure increases subsequent risk of breast cancer in postmenopausal women in the Health Examinees-Gem study

Epidemiological evidence suggests that hypertension is associated with breast cancer risk. However, previous studies disregard blood pressure components in the healthy population. We aimed to examine the relationship between systolic and diastolic blood pressure and breast cancer risk in a Korean population-based prospective cohort. A total of 73,031 women from the Health Examinees Gem Study were followed from baseline (2004 to 2013) through 2018. Systolic and diastolic blood pressure were measured by trainee physicians at baseline recruitment and then categorized based on the international guidelines for clinical hypertension. Associations between systolic and diastolic blood pressure with overall breast cancer and stratified by premenopausal and postmenopausal status were evaluated using adjusted multivariable Cox proportional hazard regression. A total of 858 breast cancer cases were recorded for a median follow-up period of 9 years. Compared with the normal DBP category (< 85 mmHg), the normal-high category was positively associated with breast cancer risk in postmenopausal women (85–89 mmHg, HR 1.73 95% CI 1.28–2.33), but not in premenopausal women (85–89 mmHg, HR 0.87 95% CI 0.56–1.35). Similar results were found when all cases of self-reported hypertension were excluded. Results for SBP did not show a significant association with breast cancer risk. The association between DBP and breast cancer suggests DBP could be an important factor in cancer prevention, especially for women after menopause. Our study provides a first detailed approach to understanding the importance of diastolic blood pressure for breast cancer prevention and warrants further investigation.

Actions Speak Louder Than Words: Health Behaviours and the Literacy of Future Healthcare Professionals

Our everyday behaviours in life can positively and negatively impact our health, thus cumulatively shaping our lifestyles as more or less healthy. These behaviours are often determined by our knowledge, literacy, motivations and socioeconomic backgrounds. The authors aimed to assess health behaviours and explore variables that may affect persons studying to become future healthcare professionals in Poland. This study was conducted with a group of 275 undergraduate students attending the Poznan University of Medical Sciences representing six different majors of study. We used self-reported, cross-sectional survey conducted through the use of a questionnaire that consisted of one standardised scale (Juczyński’s Health Behaviour Inventory) as well as a self-developed health literacy measure. The students showed average to high levels of health-promoting behaviours (mean HBI = 82.04 ± 11.26). Medium to strong associations were found between these behaviours and high scores on the health literacy scale (p = 0.001, r = 0.45 between total scores of the two scales). Dietetics students and female respondents scored significantly better on both scales, which suggests that their self-reported behaviours and health literacy were higher than those of other participants. Exhibiting health-protective behaviours and high health literacy is likely to result in the better individual health of our respondents, but, more importantly, will also influence their future professions. As members of the healthcare workforce they will be responsible for the health of the population and it is crucial for them not only to provide care, education, and guidance, but also to act as role-models for their patients and society.

Reimbursement of Digital Therapeutics: Future Perspectives in Korea

Although the global digital therapeutics (DTx) market is rapidly growing and whether the health insurance system will cover DTx is a very important issue, there are currently no standards in Korea after the approval stage of the Ministry of Food and Drug Safety. Regarding this issue, this study examined the concepts and characteristics of DTx and compared major countries (the U.S., the U.K., Germany, Japan, and Australia) reimbursement policies for DTx, thus clarifying the political implications for introducing DTx in Korea.

Digital health is rapidly growing worldwide and its area is expanding from wellness to treatment due to digital therapeutics (DTx). This study compared DTx in the Korean context with other countries to better understand its political and practical implications. DTx is generally the same internationally, often categorized as software as a medical device. It provides evidence-based therapeutic interventions for medical disabilities and diseases. Abroad, DTx support entailed state subsidies and fundraising and national health insurance coverage. In the case of national health insurance coverage, most cases were applied to mental diseases. Moreover, in Japan, DTx related to hypertension will possibly be under discussion for national health insurance coverage in 2022. In overseas countries, coverage was decided only when the clinical effects were equivalent to those provided by existing technology, and in the UK, real usage data for DTx and associated evaluations were reflected by national health coverage determination. Prices were either determined through closed negotiations with health insurance operating agencies and manufacturers or established based on existing technology. Concerning the current situation, DTx dealing with various diseases including hypertension are expected to be developed near in the future, and the demand for use and compensation will likely increase. Therefore, it is urgent to define and prepare for DTx, relevant support systems, and health insurance coverage listings. Several support systems must be considered, including government subsidies, science/technology funds, and health insurance.

A Randomized, Double-blind, Active-controlled, Two Parallel-Group, Optional Titration, Multicenter, Phase IIIb Study to Evaluate the Efficacy and Safety of Fimasartan Versus Perindopril Monotherapy With and Without a Diuretic Combination in Elderly Patients With Essential Hypertension

PURPOSE

The efficacy and tolerability of fimasartan in elderly patients have not been fully evaluated. This study was therefore conducted to determine the efficacy and tolerability of fimasartan compared with perindopril in elderly Korean patients aged >70 years with essential hypertension (defined by a mean sitting systolic blood pressure [SBP] ≥140 mm Hg).

METHODS

This randomized, double-blind, active-controlled, 2 parallel-group, optional titration, multicenter, Phase IIIb trial (FITNESS [Fimasartan in the Senior Subjects]) enrolled 241 patients from 23 cardiac centers in the Republic of Korea between August 2017 and December 2019. After the placebo run-in period, treatment started with fimasartan 30 mg or perindopril arginine 2.5 mg once daily at a 1:1 ratio; if BP was not controlled at week 4, the dose was doubled. If BP was not controlled at week 8, a diuretic combination (fimasartan 60 mg/hydrochlorothiazide 12.5 mg or perindopril arginine 5 mg/indapamide 1.25 mg) was administered. After 16 weeks of the double-blind treatment, the patients with controlled BP participated in an 8-week open-label extension study, with the 2 groups unified by fimasartan 60 mg with or without hydrochlorothiazide 12.5 mg for 8 weeks. The primary outcome was a change in SBP for 8 weeks. The secondary outcomes included a change in sitting diastolic BP (DBP) for 8 weeks and changes in SBP and DBP for 4, 16, and 24 weeks.

FINDINGS

At week 8, mean SBP significantly decreased from baseline in both groups: -14.2 (14.4) mm Hg in the fimasartan group and -9.0 (16.1) mm Hg in the perindopril group. The difference between the 2 groups was 5.4 (2.1) mm Hg, indicating the noninferiority of fimasartan to perindopril. Moreover, fimasartan exhibited a higher BP-lowering effect than perindopril (P = 0.0108). In addition, reductions in SBP and DBP from baseline to weeks 4, 8, and 16 were significantly greater in the fimasartan group than in the perindopril group, although the SBP reduction was comparable at week 16. Both groups reported an excellent mean compliance rate of 97.4% (4.7%) through week 16. During the study period, 82 adverse events were reported in 52 patients, 40 in the fimasartan group and 42 in the perindopril group (P = 0.4647). Dizziness was the most commonly reported adverse event (7 cases). Remarkably, only 1 case of orthostatic hypotension was reported during the study period.

IMPLICATIONS

In elderly patients with essential hypertension, fimasartan 30 to 60 mg with a possible hydrochlorothiazide 12.5-mg combination was noninferior to perindopril 2.5 to 5 mg with a possible indapamide 1.25-mg combination. Furthermore, fimasartan exhibited higher BP-lowering efficacy than perindopril. There was no difference in tolerability between the 2 groups. Clinicaltrials.gov Identifier: NCT03246555.

Central blood pressure lowering effect of telmisartan-rosuvastatin single-pill combination in hypertensive patients combined with dyslipidemia: A pilot study

This multicenter, phase 4, Prospective Randomized Open, Blinded End‐point (PROBE) study aimed to evaluate safety and efficacy of telmisartan/rosuvastatin single‐pill combination (SPC) therapy on lowering central blood pressure (BP) compared with telmisartan monotherapy in hypertensive patients with dyslipidemia in Korea. Study was terminated earlier than planned due to COVID‐19 pandemic, thus should be considered as a pilot study. Among 125 patients who met the inclusion criteria of hypertension and dyslipidemia (defined as 10‐year Atherosclerotic Cardiovascular Disease risk score over 5%), 80 patients went through 4‐week single‐group run‐in period with telmisartan 40–80 mg, then randomized to telmisartan 80 mg + rosuvastatin (10 or 20 mg) SPC group or telmisartan 80 mg monotherapy group. The central/brachial BP, brachial‐ankle pulse wave velocity (baPWV), and augmentation index (AIx) were assessed at baseline and 16 weeks later. Mean brachial SBP changed from 135.80 ± 14.22 mmHg to 130.69 ± 13.23 mmHg in telmisartan/rosuvastatin group and from 134.37 ± 12.50 mmHg to 133.75 ± 12.30 mmHg in telmisartan monotherapy group without significant difference (between‐group difference p = .149). Mean central SBP were reduced significantly in the telmisartan/rosuvastatin group with change from 126.72 ± 14.44 mmHg to 121.56 ± 14.56 mmHg while telmisartan monotherapy group showed no significant change (between‐group difference p = .028). BaPWV changed from 1672.57 ± 371.72 m/s to 1591.75 ± 272.16 m/s in telmisartan/rosuvastatin group and from 1542.85 ± 263.70 m/s to 1586.12 ± 297.45 m/s in telmisartan group with no significance (between‐group difference p = .078). Change of AIx had no significant difference (between‐group difference p = .314). Both groups showed excellent compliance rate of 96.9 ± 4.5% with no significant difference in adverse rate. Telmisartan/rosuvastatin SPC therapy was more effective in lowering central BP compared with the telmisartan monotherapy. The results of this study showed benefit of additive statin therapy in hypertensive patients combined with dyslipidemia.

Suboptimal Management Status of Younger Hypertensive Population in Korea

BACKGROUND AND OBJECTIVES

Hypertension (HTN) is the most contributable risk factor for cardiovascular disease. May Measurement Month (MMM) is a global initiative to raise awareness of HTN and act as a temporary solution to the lack of screening programs worldwide.

METHODS

An opportunistic cross-sectional survey of participants aged ≥18 was carried out in May 2019. Over 10,000 participants were recruited in the MMM 2019 Korea, with a slogan of "A simple measure to save lives - #checkyourpressure."

RESULTS

A total of 9,950 participants with valid clinical blood pressure (BP) data were used for analysis. All participants were Korean in ethnicity. The mean age was 57.2±21.2 years, 57.8% were females, and the mean body mass index was 23.4±3.3 kg/m². Among the enrolled population, 20.1% were less than 30 years old, and 5.0% were 30-39 years old. 37.0% of the participants reported a previous diagnosis of HTN, and 91.3% of those diagnosed were on antihypertensive medications. Notably, more than 20% of the participants had not measured their BP during the last 12 months, and the awareness rate in the young hypertensive participants (aged <40) was less than 10%. Among hypertensive participants, the treatment rate was 69.3%, and the control rate among those taking medications was 61.2%.

CONCLUSION

MMM 2019 Korea campaign reported high BP control rates in individuals with HTN, reaching 60%. However, the awareness rate in young hypertensive participants was less than 10% along with suboptimal management status. The MMM 2019 Korea again raised the importance of regular BP measurement in the younger population.

Intensive blood pressure lowering: a practical review

According to the last Hypertension guideline recommendations, it may be concluded that intensive BP lowering is only advisable in a subgroup of patients where there is a clear net benefit of targeting to lower BP goals. However, taking into account the relevance of correct BP measurement, estimates of the benefits versus the harm should be based on reliable office BP measurements and home BP measurements.

There is still debate about which BP goals are optimal in reducing morbidity and mortality in uncomplicated hypertensives and in those with associated comorbidities. In recent years, trials and meta-analyses have assessed intensive BP lowering, with some success. However, a careful examination of the results shows that current data are not easily applicable to the general hypertensive population.

This article reviews the evidence on and controversies about intensive BP lowering in general and in specific clinical situations, and the importance of obtaining reliable BP readings in patients with hypertension and comorbidities.

Association between Use of Hydrochlorothiazide and Nonmelanoma Skin Cancer: Common Data Model Cohort Study in Asian Population

Although hydrochlorothiazide (HCTZ) has been suggested to increase skin cancer risk in white Westerners, there is scant evidence for the same in Asians. We analyzed the association between the use of hydrochlorothiazide and non-melanoma in the Asian population using the common data model.

METHODS

A retrospective multicenter observational study was conducted using a distributed research network to analyze the effect of HCTZ on skin cancer from 2004 to 2018. We performed Cox regression to evaluate the effects by comparing the use of HCTZ with other antihypertensive drugs. All analyses were re-evaluated using matched data using the propensity score matching (PSM). Then, the overall effects were evaluated by combining results with the meta-analysis.

RESULTS

Positive associations were observed in the use of HCTZ with high cumulative dose for non-melanoma skin cancer (NMSC) in univariate analysis prior to the use of PSM. Some negative associations were observed in the use of low and medium cumulative doses.

CONCLUSION

Although many findings in our study were inconclusive, there was a non-significant association of a dose-response pattern with estimates increasing in cumulative dose of HCTZ. In particular, a trend with a non-significant positive association was observed with the high cumulative dose of HCTZ.
