Besides lung transplantation, pulmonary thromboembolectomy is the only effective therapeutic option for chronic thromboembolic pulmonary hypertension. It is however associated with a considerably high hospital mortality between 6.6 to 23%. Proper patient selection is critical when considering a patient for pulmonary thromboembolectomy. And It cannot be overemphasised that the key to the success of the operation is complete endarterectomy of the entire pulmonary arterial tree. We report that pulmonary thromboendarterectomy under total circulatory arrest was an effective and safe method in the surgical correction of the chronic thrornboernbolic pulmonary hypertension and enabled complete removal of superimposed peripheral organized thrombi in a good operative field.

Essential hypertension is a typical chronic disease requiring adequate and continuous management. Many studies supported that self-care was the essential factor to promote the wellbeing of hypertensives and self-efficacy increased healthy, behavior. The comprehensive self-regulation program was conducted as a nursing intervention on the promotion self-care performance for hypertensives in company. And this self-regulation program was recommended to apply for hypertensives in rural area. The purpose of this study is to identify the general characteristics affecting self-care and interrelationship among the factors including self-care, self-efficacy, HLOC, perceived benefits, barriers and family support. 40 subjects were interviewed from Dec. 1996 to Jan. 1997 and the data was analyzed by the SPSS PC+ program with t-test and multiple correlation to determine the variables affecting the self-care behavior. The results were as follows: 1) Level of self-care was significant difference according to sex(t= -2.27, p=.0l9). religion (t=1.57, p=.055) and smoking habit (t=4.42, P=.000). Perceived self-efficacy was more significantly high among the non-smoking group (t=3.25, P=.000) and female group (t=-2.534, p=.0l3). 2) There were significant positive correlation among the variables: self-care and self-efficacy (r=.5460, p=.000), external-LOC and self-care(r=.2548, p=.056), external-LOC and self-efficacy(r =. 2901, p=.035), self-efficacy and perceived benefits (r=3307, p=.019). And there were significant negative correlation between self-care and barriers (r=-.5438, p=. 000), self-efficacy and barriers (r= - .4153, p=.004). From the above results, it can be concluded that the self-care is more required in male hypertensives and self-efficacy is one of the important factors to increase healthy behavior in cluding self-care. Thus self-regulation program can be recommended in the management of the hypertensives in community settings.

Surveys were carried out from April to December of 2003 to collect the information on hypertension patients for the detailed analysis. Totally, 1,423 patients, who have been registered to the public health center or its branch located in a small city with both urban and countryside characteristics in Kyungsangbuk-Do area, were the subjects of this investigation. The purpose of this research was to examine the health situation of the hypertension patients and to understand the official state of their management program and their own efforts to control the blood pressure, so that we could develop the better program to protect the patients more efficiently and systematically. Eventual purpose was to provide the patients at high risk with the essential informations to prevent the onset of the disease and to promote their health conditions by early diagnosis. Most patients, registered to the public health center, were relatively obedient to the prescription, however, the incidence of being checked up regularly was low. It was turned out that the patients showed a low tendency to practice to maintain the healthy life style such as the proper eating habit or the effort to control the stress. So. it is necessary to develop the strategy and the management program to enhance the self-nursing activities to control the patients' blood pressure at the proper level. In addition, multidisciplinary approaches should to be done for efficient and effective care for hypertension patients. Finally, systematic management of hypertension patients is required to classify the duty and role for caring patients among those health care system.

Purpose: The objective of this study was to identify the predictors of self-care behaviors among elderly patients with hypertension using quantile regression method. Methods: A total of 253 elderly patients diagnosed with hypertension was recruited via 3 different medical clinics for the study. The quantile regression and a liner regression was conducted using Stata 12.0 program by analyzing predictors of self-care behaviors. Results: In the ordinary least square, self-efficacy, period of disease, and education level explained 42% of the variance in self-care activities. In the quantile regression, affecting predictors of self-care behaviors were self-efficacy for all quantiles, the period of disease for from 60% quantile to 90% quantile, education level for 20%, 30%, and 50% quantiles, economic status for 10%, 50%, and 60% quantiles, age for 10%, 70% quantiles, fatigue for 10% quantile, knowledge about hypertension for 10% and 20% quantiles, and depression for 30% and 40% quantiles. Conclusion: The affecting predictors of self-care behaviors among elderly with hypertension were different from the level of self-care behaviors. These results indicated the significance in assessing predictors according to the level of self-care behaviors when clinical nurses examine the patients' health behaviors and plan any intervention strategies. Specially, education level and knowledge about hypertension were the significant predictors of self-care activities for low quantiles. Clinical nurses may promote self-care activities of the given population though health education programs.

Purpose: To investigate the effectiveness of aromatherapy on blood pressure, heart rate variability, aortic pulse wave velocity and the aortic augmentation index of essential hypertensive patients. Methods: Using a coin toss, 22 participants were assigned to the experimental group and 20 to the control. The experimental group was given a blend of oils of lemon (Citrus limonum), lavender (Lavandula angustifolia), and ylang ylang (Cananga odorata) which were prepared in the ratio of 2:2:1, respectively. The control group was given an artificial lemon fragrance of Limonene (35 cc) and Citral (15 cc) mixture. The experiment, inhalation, was conducted for 3 weeks (2 min per inhalation, 2 times per day) to both groups. Results: There was a noticeable difference in systolic blood pressure between the groups (p=.001), however the difference in diastolic blood pressure between the two groups was not significant. There was a notable difference in sympathetic nerve system activity of heart rate variability (p=.047). However, the differences in aortic pulse wave velocity or the aortic augmentation index were not significant. Conclusion: Aromatherapy is effective in lowering systolic blood pressure and sympathetic nerve system activity.

Background: This study aimed to research on how adherence and blood control could make a difference when it comes to develop complications. Methods: The study's subjects were 255,916 patients who were newly diagnosed with hypertension in 2009 using data collected by National Health Insurance Cooperation. Patients are considered as a group under adherence if visit days and prescription days are more than 300 days. Patients are considered to have successfully controled their hypertension based on actual value measured by National Health Insurance Cooperation and the study takes a look at whether they were diagnosed with complications of cerebrocardiovascular disease in 2012. Chi-square test and logistic regression was used to analyze. Results: Patients who were able to control their hypertension show 0.80 times chance of developing cerebrovascular disease, and 0.89 times chance of developing cardiocerebrovascular disease. The group of adherence shows lower chance of developing complication in general than the group of non-adherence. Conclusion: The study revealed that hypertension's constant treatment could control the blood pressure and prevent complications. It is important that encourages patients to effort for persistent treatment for reducing complication.

Purpose: The purpose of this study was to evaluate the effect of aerobic exercise on serum lipids, body weight, and body mass index in adults with hypertension using a systematic review and meta-analysis. Methods: Six electronic databases (PubMed, EMBASE, Co-chrane library, CINAHL, PsycINFO, SPORTDiscus) and five domestic databases were searched for randomized controlled trials studies. We used random effect models to derive weighted mean differences (WMD) and their 95% confidence intervals (CI) of aerobic exercise on serum lipids, body weight, and body mass index. Results: Nineteen studies met our inclusion criteria. In comparison with the control group, triglyceride level (TG) (-13.49 mg/dL, 95% CI: -26.74 to -0.24) and body weight (-0.62 kg, 95% CI: -1.08 to -0.16) difference between follow-up and baseline was significantly reduced in the aerobic exercise group. However, no difference was found in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and body mass index (BMI). Conclusion: Aerobic exercise is effective in reducing the TG level and body weight in adults with hypertension. In order to improve levels of serum TC, LDL-C and HDL-C of hypertensive patients, it's needed to combine other intervention methods such as diet therapy.

Objectives: This study considered the effectiveness of integrative Korean medical treatment for stress-induced hypertensive patients without the use of conventional medication. Methods: A 62-year-old female with stress-induced hypertension (HTN) was hospitalized for 33 days. Her pattern identification was ascendant hyperactivity of liver yang (Ganyangsanghang)-type HTN. Herbal medicine and acupuncture were used for the treatment: Cheonggansoyo-san for 33 days and Chunwangbosim-dan for 15 days, together with acupuncture for 20 minutes twice a day. Blood pressure was checked daily during hospitalization with a digital sphygmomanometer in the brachial artery. Results: After 33 days of treatment, blood pressure decreased. The Handicap Inventory (DHI) scale and Pittsburg Sleep Quality Index (PSQI) scores both decreased. The patient also reported fewer complaints. A five-month follow-up after discharge, with no further treatment, confirmed stable blood pressure. Symptom improvements continued with no significant side effects. Conclusions: This study indicates that Korean medical treatment is effective for stress-induced hypertensive patients.
