고혈압은 임상 현장에서 매우 흔한 질환인데 그 유병률이 국제적으로 상승세를 보이고 있다. 고혈압의 폐해는 너무 많으며 여러 장기들에 영향을 미친다. 필요 시 보통 평생 동안 치료해야 한다. 한국질병관리본부에 따르면 고혈압 유병률이 날로 증가하고 있다. 2011 조사에서 성인 중 28.9%가 고혈압이었으며, 여자 보다 남자가 약간 더 높았다. 환자를 분류하고, 혈압관련 위험을 확인하고 그리고 치료법을 안내하는 데 있어 정확한 혈압 측정은 필수적이다. 혈압계의 정확도에 영향을 미치는 요인 중 블래더 크기의 일탈이 장비 에러의 주된 원인이 된다. 혈압을 정확히 측정하기 위해, 위 팔 중심의 둘레에 따른 올바른 크기의 블래더 사용은 필수적이다. 시중의 혈압계를 조사한 결과, 커프 블래더들이 국제 규격 ISO 81060-1:2007에서 권유된 크기와 다름을 알 수 있었다. 블래더가 클 경우 혈압이 더 낮게 나오고, 더 작을 경우 더 높게 나온다는 것은 잘 알려져 있다. 미)심장협회(AHA)가 권고하는 어른용 블래더의 크기는 17-25cm의 팔 둘레를 가진 작은 어른, 24-32 cm의 팔 둘레를 가진 어른, 32-42cm의 팔 둘레를 가진 대다수 어른, 그리고 42-50cm의 팔 둘레를 가진 비만 어른으로 구분 된다. 반면에 한국 어른의 팔 둘레는 23-31cm에 불과하므로 AHA의 어른용 블래더 한 가지에 해당한다. 23-31cm의 팔 둘레를 가진 한국 어른을 위한 블래더의 종류는 ISO 81060-1을 따를 경우 3 개의 블래더가 필요하다. 병원들은 어른 환자들을 위해 보통 하나 혹은 두 가지 크기의 서양식 커프를 사용한다. 이 때문에 일부 환자들은 정확한 혈압 측정을 기대할 수 없다. 한국인에서 취합한 인체치수 참조 데이터에 기초한 블래더의 크기는 한국에서 가장 정확한 혈압을 측정하는데 도움이 될 것이다.

Objectives: Masked hypertension is associated with metabolic risks and increased risk of cardiovascular disease. The purpose of this study was to identify the frequency of and risk factors of masked hypertension in Korean workers. Methods: The study was conducted among 121 employees at a hotel in Gyeongju, Korea, from December 2008 to February 2009. We measured blood pressure (BP) both in the clinic and using 24-hour ambulatory BP monitors for all subjects. Hypertension was defined independently by both methods, and subjects were classified into four groups: true normotension, masked hypertension, white coat hypertension, and sustained hypertension. Results: The frequency of masked hypertension in our study group was 25.6%. Compared with true normotension, the factors related to masked hypertension were male gender (odds ratio [OR], 10.7; 95% confidence interval [CI], 1.41 to 81.09), aging one year (OR, 0.88; 95% CI, 0.78 to 0.99), clinic BP 120-129 /80-84 mmHg (OR, 8.42; 95% CI, 1.51 to 46.82), clinic BP 130-139 / 85-89 mmHg (OR, 12.14; 95% CI, 1.80 to 81.85), smoking (OR, 5.51; 95% CI, 1.15 to 26.54), and increase of total cholesterol 1 mg / dL (OR, 1.05; 95% CI, 1.02 to 1.08). In males only, these factors were clinic BP 120-129/ 80-84 mmHg (OR, 15.07; 95% CI, 1.55 to 146.19), clinic BP 130-139/ 85-89 mmHg (OR, 17.16; 95% CI, 1.56 to 189.45), smoking (OR, 11.61; 95% CI, 1.52 to 88.62), and increase of total cholesterol 1 mg/dL (OR, 1.05; 95% CI, 1.01 to 1.09). Conclusions: The frequency of masked hypertension was high in our study sample. Detection and management of masked hypertension, a known strong predictor of cardiovascular risk, could improve prognosis for at-risk populations.

Oriental medicine prescription has been used for the treatment of various clinical symptoms associated with cerebral apoplexy. However, single herb drug does not used cerebral apoplexy and there mechanisms of action have not been defined, and it is not yet known what effects they have on the hemodynamics of cerebral circulation. The study was aimed to investigate the effect batryticatus bombycis(BB) on the vascular systems including changes in blood pressure (BP), and regional cerebral blood flow (rCBF) and of male Sprague-Dawely rats. The changes in rCBF were determinated by laser-Doppler flowmetry. 1. Blood pressure was not affected by BB in rats. 2. rCBF was increased by BB in a dose-dependent manner. 3. Pretreatment with methylene blue(1mg/kg), and propranolol(1mg/kg) did not inhibited BB induced increased in rCBF. 4. Pretreatment with propranolol(1mg/kg) was increased by BB in a dose-dependent manner in blood perssure. 5. Pretreatment with ODQ($10{\mu}g/kg$) and L-NNA(1mg/kg) were inhibited BB induced increased in rCBF. 6. Pretreatment with L-NNA(1mg/kg) was increased rCBF in a dose-dependent manner. These results suggest that BB causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased in rCBF is also mediated by nitric oxide synthease and guanylate cyclase.

The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n=371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P<0.05) and with serum triglyceride (TG) levels in women (P<0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P<0.05) and serum TGs (P<0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults.

Noise may cause damage of the auditory system, hypertension, and cardiovascular disease. However, we haven't the data enough to be available for understanding various effects of noise on the human body. The current study was prospectively designed to investigate the changes of the cardiac factors and cerebral hemodynamics following a transient exposure to noise in young people. 80 subjects (mean aged $23.45\pm2.40$ years) participated in this experiment and were exposed to excavator-noise with 90 decibels for 15 minutes using ear-phone. Cardiac factors such as heart rate (HR), blood pressure (BP) and heart rate-systolic pressure product (RPP), and cerebral hemodynamics such as mean blood flow velocities (Vm), pulsatility indexes (PI), resistance indexes (RI) and mean blood flow velocities at breathing-hold (Vh) in the middle (MCA), anterior (ACA) and posterior cerebral arteries (PCA) were measured before (baseline) and during the noise-exposure. Although there were individual differences in above mentioned parameters, HR, systolic and diastolic BP, RPP, MCA-Vm, MCA-PI, MCA-RI, ACA-Vm, ACA-PI, ACA-RI, PCA-Vm, PCA-PI, and PCA-RI during the noise-exposure decreased compared with the baselines (P<0.05 or P<0.01), The findings of the present study suggest that a transient exposure to excavator-noise at rest causes changes in the cardiac factors and cerebral hemodynamics with individual differences. Further studies need to be carried out for clarifying the effects of longer exposure and combined mental activity with noise exposure.

본 연구는 기립성 저혈압이 동반된 경수부 척수손상 환자에서 플루드로코티손의 치료 효과에 대해 알아보고자 하였다. 기립경사도 검사를 통해 기립성 저혈압으로 진단된 경수부 척수손상 환자 26명을 무작위로 배정하였고, 보존적 치료 혹은 추가로 플루드로코티손 치료 중 한가지를 시행하였다. 플루드로코티손은 주마다 0.1mg에서 0.2mg로 증량하여 총 2주간 투약하였고, 초기 및 2주 후의 혈압 및 심박수, 혈액학적 검사 수치의 변화를 평가하였다. 치료 2주 후에 치료군에서 기저 혈압의 유의미한 상승이 나타났다(p<.05). 기립성 혈압 감소의 비율 분석에서 치료군의 기립성 혈압 감소가 덜 나타나는 경향성을 보였다. 플루드로코티손 치료군의 7.69%에서 경증의 이상 반응을 보고하였다. 이를 통해 플루드로코티손이 기저 혈압의 상승 및 기립성 저혈압 감소를 통해 심혈관계 합병증 방지 및 재활치료 지속 등의 치료 효과를 나타내었음을 알 수 있으며, 척수손상 환자의 기립성 저혈압에서 하나의 치료 방안으로 고려해볼 수 있다고 생각된다.

Background: Oriental lifestyle for treating diseases has been developed and well-accepted for a long time among Koreans. Sasang Constitution theory, originated from Korean traditional medicine, suggests that medication treatment should be differentiated by each patient's body classification (So-yang [SY], So-eum [SE], Tae-yang [TY], and Tae-eum [TE]), in contrary to western medicine's theory that medication should be applied equally by disease indication without such classification. However, the pharmacotherapeutic outcomes of these theories have not been compared to date. In this study, we aimed to compare the two theories by evaluating blood pressure (BP), which is lowered as a therapeutic outcome, among hypertensive patients taking angiotensin II receptor blockers (ARBs) or calcium channel blockers (CCBs), two most commonly used antihypertensive classes in Korea. Methods: From April 2006 to June 2012, we retrospectively collected data on hypertensive patients with Sasang Constitution classification at Kyunghee University Hospital at Gangdong, one of the East-West collaborative medical centers in Korea. We collected information on age, gender, underlying diseases, antihypertensive drugs (ARB, CCB, ARB+CCB), and BP by reviewing the electronic medical records. We excluded patients with missing blood pressure at baseline or follow-up, or those who had a change in their antihypertensive drug class during follow-up. Results: We selected a total of 573 patients (SY: 165, SE: 158, TY: 0, TE: 250). Baseline BPs were on average 139.0/82.0 mmHg for SY, 137.8/78.5 mmHg for SE, and 138.7/79.2 mmHg for TE. In all three groups, CCBs were the most prescribed, followed by combination therapy with ARB+CCB, then ARBs. BP reduction after 1 month of initial medication was significantly different among the drug classes, but not in Sasang constitutional classification (ARB [SY: -12.4/-4.7, SE: -12.3/-2.5, TE: -8.6/-1.8], CCB [SY: -12.3/-5.4, SE: -13.0/-2.3, TE: -10.8/-6.0], ARB+CCB [SY: -15.6/-6.7, SE: -18.4/-8.1, TE: -20.2/-6.7], drug [$P{\leq}0.05$/P>0.05], constitutional type [P>0.05/P>0.05]). Conclusion: We observed significant differences in reduction of blood pressure by classes of drugs (ARB+CCB>CCB>ARB) but not by Sasang constitutional classification. Therefore, current approach of antihypertensive pharmacotherapy assisted by Western medicine is appropriate for treatment of hypertension. However, further larger scale or prospective studies are required in order to confirm these results.

■Objectives This study aimed to collect and analyze clinical studies on the significance of acupuncture in the treatment of hypertension among Korean patients. ■Methods Among Korean patients with a blood pressure (BP) of 120 mmHg or higher and a diastolic BP of 80 mmHg or higher, those, treated with acupuncture only, were included. A literature search was conducted through 'Embase', 'Medline', 'Science and Technology Information Integration Service (NDSL)', 'Traditional Korean Knowledge Portal (OASIS)', 'PubMed', and 'Scopus'. The search keywords were (hypertension OR 'blood pressure') AND acupuncture. The papers, published before the day of the search (02. January 2022), were included in this study. ■Results Among the 12 selected papers, seven involved randomized controlled trial (RCT), four before-and-after studies, and one case series. The number of RCTs has increased yearly. The treatment methods used in the studies included needle acupuncture in eight studies, auricular acupuncture in two, pharmacopuncture in one, and si-acupuncture in one. The average numbers of patients enrolled in RCTs, before-and-after studies, and case series were 21.1, 30, and 23 respectively. Six studies were conducted on prehypertensive patients, two on stage 1 hypertension patients, and four on stage 2 hypertension patients. The involved acupoints have been reported to be ST36 in eight papers, LI11 in four papers, and PC6 in three papers. The treatment period lasted for < 1 week in eight studies and 8 weeks in four studies. Acupuncture successfully lowered blood pressure in nine out of 12 studies ■Conclusions Acupuncture is a viable alternative treatment option for prehypertensive patients, who are not taking medications. Additionally, it is also useful in further lowering the BP of patients with stage 1 and stage 2 hypertension in the short term. Large-scale and long-term studies on acupuncture for hypertension should be conducted.

목적 : 소아 청소년에서 고혈압의 유병률이 증가하면서 혈압의 측정에 대한 관심이 증가하고 있다. 활동 혈압 감시는 진성 고혈압과 백의 고혈압의 진단에 유용하다고 알려져 있어 우리나라 소아 청소년을 대상으로 활동 혈압 감시의 임상적 유용성을 알아보기 위해 본 연구를 시행하였다. 방법: 2002년 1월부터 2010년 2월까지 경북대학교병원 소아청소년과 및 내과를 방문하여 활동 혈압 감시를 시행한 6세부터 18세까지의 소아 및 청소년 51명을 대상으로 하였다. 외래에서 측정한 수시 혈압과 활동 혈압 감시 결과로 계산된 평균 혈압, 혈압 부하 및 야간 하강 정도를 환자들의 임상적 특징과 진단 별로 비교하였다. 결과:전체 51명의 환자 중 남자가 49명이었으며 평균연령은 $17.8{\pm}1.8$세였고 19명(37.3%)이 비만이었다. 활동 혈압 감시 시행 중 평균 유효 측정횟수는 37.8회, 유효 측정률은 94.3%이었다. 활동 혈압 감시 결과 진성 고혈압 환자가 37명(72.5%)이 었고 이 중 1명이 가면 고혈압이었다. 7명(14%)은 백의 고혈압으로 진단되었으며 나머지 7명은 수시혈압과 24시간 활동 혈압 모두 정상이었다. 백의 고혈압으로 진단된 7명 중 5명이 고혈압 전 단계였다. 진성 고혈압 환자에서 평균 수축기와 이완기 혈압 부하는 정상 혈압 소아에 비해 유의하게 높았고(P<0.001) 야간 강하는 10% 이하였으나 통계적 유의성은 없었다. 비만 환자에서 평균 수축기, 이완기 혈압 및 혈압 부하가 유의하게 높았다(P<0.001). 결론 : 본 연구에서 소아 청소년에서 활동 혈압 감시가 진성 고혈압 및 백의 고혈압을 진단하는데 유용하였으며 백의 고혈압을 가진 소아의 상당수가 고혈압 전 단계에 해당되어 향후 이들에 대한 지속적인 추적 관찰이 필요한 것으로 생각된다.
