Background and Objectives:
This study aimed to investigate the association between cardiovascular events and 2 different levels of elevated on-treatment diastolic blood pressures (DBP) in the presence of achieved systolic blood pressure targets (SBP).
Methods:
A nation-wide population-based cohort study comprised 237,592 patients with hypertension treated. The primary endpoint was a composite of cardiovascular death, myocardial infarction, and stroke. Elevated DBP was defined according to the Seventh Report of Joint National Committee (JNC7; SBP <140 mmHg, DBP ≥90 mmHg) or to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) definitions (SBP <130 mmHg, DBP ≥80 mmHg).
Results:
During a median follow-up of 9 years, elevated on-treatment DBP by the JNC7 definition was associated with an increased risk of the occurrence of primary endpoint compared with achieved both SBP and DBP (adjusted hazard ratio [aHR], 1.14; 95% confidence interval [CI], 1.05–1.24) but not in those by the 2017 ACC/AHA definition. Elevated ontreatment DBP by the JNC7 definition was associated with a higher risk of cardiovascular mortality (aHR, 1.42; 95% CI, 1.18–1.70) and stroke (aHR, 1.19; 95% CI, 1.08–1.30). Elevated on-treatment DBP by the 2017 ACC/AHA definition was only associated with stroke (aHR, 1.10;95% CI, 1.04–1.16). Similar results were seen in the propensity-score-matched cohort.
Conclusion
Elevated on-treatment DBP by the JNC7 definition was associated a high risk of major cardiovascular events, while elevated DBP by the 2017 ACC/AHA definition was only associated with a higher risk of stroke. The result of study can provide evidence of DBP targets in subjects who achieved SBP targets.

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/m 2 . 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 withHTN, 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.

The Korean Journal of Internal Medicine 2021;36(3):617-628
Background/Aims:
Although it is near concluded that renin-angiotensin system inhibitors do not have a harmful effect on coronavirus disease 2019 (COVID-19), there is no report about whether angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) offer any protective role. This study aimed to compare the association of ARBs and ACEIs with COVID-19-related mortality.
Methods:
All patients with COVID-19 in Korea between January 19 and April 16, 2020 were enrolled. The association of ARBs and ACEIs with mortality within 60 days were evaluated. A comparison of hazard ratio (HR) was performed between COVID-19 patients and a retrospective cohort of pneumonia patients hospitalized in 2019 in Korea.
Results:
Among 10,448 COVID-19 patients, ARBs and ACEIs were prescribed in 1,231 (11.7%) and 57 (0.6%) patients, respectively. After adjusting for age, sex, and history of comorbidities, the ARB group showed neutral association (HR, 1.034; 95% CI, 0.765 to 1.399; p = 0.8270) and the ACEI groups showed no significant associations likely owing to the small population size (HR, 0.736; 95% CI, 0.314 to 1.726; p = 0.4810). When comparing HR between COVID-19 patients and a retrospective cohort of patients hospitalized with pneumonia in 2019, the trend of ACEIs showed similar benefits, whereas the protective effect of ARBs observed in the retrospective cohort was absent in COVID-19 patients. Meta-analyses showed significant positive correlation with survival of ACEIs, whereas a neutral association between ARBs and mortality.
Conclusions
Although ARBs or ACEIs were not associated with fatal outcomes, potential beneficial effects of ARBs observed in pneumonia were attenuated in COVID-19.

Background/Aims:
The clinical characteristics of patients with masked uncontrolled hypertension (MUCH) have been poorly defined, and few studies have investigated the clinical predictors of MUCH. We investigated the demographic, clinical, and blood pressure (BP) characteristics of patients with MUCH and proposed a prediction model for MUCH in patients with hypertension.
Methods:
We analyzed 1,986 subjects who were enrolled in the Korean Ambulatory Blood Pressure Monitoring (Kor-ABP) Registry and taking antihypertensive drugs, and classified them into the controlled hypertension (n = 465) and MUCH (n = 389) groups. MUCH was defined as the presence of a 24-hour ambulatory mean systolic BP ≥ 130 mmHg and/or diastolic BP ≥ 80 mmHg in patients treated with antihypertensive drugs, having normal office BP.
Results:
Patients in the MUCH group had significantly worse metabolic profiles and higher office BP, and took significantly fewer antihypertensive drugs compared to those in the controlled hypertension group. Multivariate logistic regression analyses identified high office systolic BP and diastolic BP, prior stroke, dyslipidemia, left ventricular hypertrophy (LVH, ≥ 116 g/m2 for men, and ≥ 96 g/m2 for women), high heart rate (≥ 75 beats/min), and single antihypertensive drug use as independent predictors of MUCH. A prediction model using these predictors showed a high diagnostic accuracy (C-index of 0.839) and goodness-of-fit for the presence of MUCH.
Conclusions
MUCH is associated with a high-normal increase in office BP and underuse of antihypertensive drugs, as well as dyslipidemia, prior stroke, and LVH, which could underscore achieving optimal BP control. The proposed model accurately predicts MUCH in patients with controlled office BP.

Korean Circulation Journal 2019;49(11):1035-1048
BACKGROUND AND OBJECTIVES: Discrepancy in blood pressure (BP) control rate may be owed to different risk factors associated with elevated systolic and diastolic BP (SBP and DBP). METHODS: In a nationally representative survey of Korean population with BP measurements, a total of 5,100 participants with hypertension was included in the analyses. Three separate types of control rates were calculated: SBP, DBP, and (combined) S&DBP among all participants with hypertension and participants with treated hypertension, separately. Control rates were compared across sex and age groups. Multivariable logistic regression was used to identify demographic factors associated with SBP, DBP, and S&DBP control rates, separately. RESULTS: In total, SBP, DBP, and S&DBP control rates were 63.0%, 63.7%, and 42.5% among all hypertension patients, and 77.5%, 87.4%, and 71.6% among treated hypertension patients. Men aged 40–49 years with hypertension and 30–39 years treated for hypertension had the highest SBP control rate (74.6% and 96.2%), which decreased by older age. Inversely, DBP control rate progressively increased with older age. SBP control rate among women with hypertension was the highest in 40–49 years (67.0%) but without linear trend by age group. Interestingly, both combined and DBP control rates were noticeably low among women aged 50–59 years. Women with body mass index ≥25 were at higher odds of having controlled SBP. Lower DBP control rate was observed in men with lower education level, higher household income, and heavy drinkers. CONCLUSIONS: Separate examination of control rates demonstrated different sex- and age-differential trends, which would have been overlooked in combined control rates.
