BACKGROUND/OBJECTIVES: The study examined the association between homocysteine and diabetes mellitus in patients with H-type hypertension and assessed the possible effect modifiers. SUBJECTS/METHODS: This cross-sectional study included 1,255 eligible participants in the 'H-type Hypertension Management and Stroke Prevention Strategic International Science and Technology Innovation Cooperation Project' among rural Chinese people with H-type hypertension. A multivariate logistic regression model was used to evaluate the relationship between homocysteine and diabetes mellitus. RESULTS: The mean level of total homocysteine (tHcy) in the diabetes mellitus population was 19.37 μmol/L, which was significantly higher than the non-diabetic patients (18.18 μmol/L). When tHcy was analyzed as a continuous variable, the odds ratio (OR) of diabetes was 1.17 (95% confidence interval [CI], 1.01-1.35; per interquartile range). When tHcy was stratified according to the quintile, the ORs for diabetes were 2.86 (95% CI, 1.22-6.69) in the highest quintile (tHcy ≥ 20.60 μmol/L) compared to the reference group (tHcy < 12.04 μmol/L). When tHcy was grouped by 15 μmol/L and 20 μmol/L, patients with tHcy ≥ 20 μmol/L had a significantly (P = 0.037) higher risk of diabetes (OR, 2.03; 95% CI, 1.04-3.96) than in those with tHcy < 15 μmol/L. Subgroup analysis showed that the tHcy-diabetes association was unaffected by other variables. CONCLUSION: In this study of rural Chinese people with H-type hypertension, the tHcy levels showed a positive association with diabetes mellitus. This independent association is unaffected by other potential risk factors.

Hyperlipidemia is one of the major factors causing the atherosclerosis of coronary arteries and well-documented modifiable risk factors of stroke, especially of the ischemic type. For Insulin-Dependent Diabetes Mellitus sufferers, if blood sugar is appropriately maintained, lipid and lipoprotein are normal, but if blood sugar is inappropriately maintained or clinical Diabetic nephropathy induces metabolic disorder of lipid, then Total cholesterol, low density lipoprotein cholesterol, triglyceride and very low density lipoprotein cholesterol levels go up and high density lipoprotein levels go down. The purpose of this study is to evaluate the effect of treatment with Ojeok-san and to observe the changes in Fasting Blood Sugar(FBS), 2 Hours Postprandial Blood Sugar(PP2h), Haemoglobin A1c(HbA1c), Total Cholesterol(T-Chol) and Triglyceride(TG). After the treatment, Fasting Blood Sugar decreased from 149mg/dl to 89mg/dl. 2 Hours Postprandial Blood Sugar decreased from l85mg/dl to 110mg/dl. Haemoglobin A1c decreased from 6.3% to 5.7%. Total Cholesterol decreased from 268mg/dl to 217mg/dl. And Triglyceride decreased from 438mg/dl to 265mg/dl. These results support a role for oriental medical therapy in treating Diabetic Hyperlipidemia. Further case studies of herbal treatment of this ailment are needed.

Objective : Emergency superficial temporal artery to middle cerebral artery (STA-MCA) anastomosis in patients with large vessel occlusion who fails mechanical thrombectomy or does not become an indication due to over the time window can be done as an alternative for blood flow restoration. The authors planned this study to quantitatively measure the degree of improvement in cerebral perfusion flow using perfusion magnetic resonance imaging (MRI) after bypass surgery and to find out what factors are related to the outcome of the bypass surgery. Methods : For a total of 107 patients who underwent emergent STA-MCA bypass surgery with large vessel occlusion, the National Institute of Health stroke scale (NIHSS), modified Rankin score (mRS), infarction volume, and hypoperfusion area volume was calculated, the duration between symptom onset and reperfusion time, occlusion site and infarction type were analyzed. After emergency STA-MCA bypass, hypoperfusion area volume at post-operative 7 days was calculated and analyzed compared with pre-operative hypoperfusion area volume. The factors affecting the improvement of mRS were analyzed. The clinical status of patients who underwent emergency bypass was investigated by mRS and NIHSS before and after surgery, and changes in infarct volume, extent, degree of collateral circulation, and hypoperfusion area volume were measured using MRI and digital subtraction angiography (DSA). Results : The preoperative infarction volume was median 10 mL and the hypoperfusion area volume was median 101 mL. NIHSS was a median of 8 points, and the last normal to operation time was a median of 60.7 hours. STA patency was fair in 97.1% of patients at 6 months follow-up DSA and recanalization of the occluded vessel was confirmed at 26.5% of patients. Infarction volume significantly influenced the improvement of mRS (p=0.010) but preoperative hypoperfusion volume was not significantly influenced (p=0.192), and the infarction type showed marginal significance (p=0.0508). Preoperative NIHSS, initial mRS, occlusion vessel type, and last normal to operation time did not influence the improvement of mRS (p=0.272, 0.941, 0.354, and 0.391). Conclusion : In a patient who had an acute cerebral infarction due to large vessel occlusion with large ischemic penumbra but was unable to perform mechanical thrombectomy, STA-MCA bypass could be performed. By using time-to-peak images of perfusion MRI, it is possible to quickly and easily confirm that the brain tissue at risk is preserved and that the ischemic penumbra is recovered to a normal blood flow state.

한국인의 연령에 따른 혈압변화와 고혈압 유병률 그리고 수축기(SBP)와 이완기(DBP)혈압 및 맥압(PP)의 변화양상을 횡단적으로 평가하였다. 지역보건소 건강검진 및 건강증진프로그램을 통해 진료된 대상자 6,570명(남2,809, 여 3,761)을 5 연령군(30, 40, 50, 60대 그리고 70세 이상)으로 구분하여 비교 분석하였다. SBP는 지속적으로 증가하였으며, 남자가 여자에 비해 높게 유지되었다. 그러나 60대 중반에서 역전되었다. DBP는 남자 30대부터 증가하여 40대에서 최고점을 이르렀다가 하강하였다. 여자는 4-50대까지 증가하다가 일정한 수준을 유지하였다. 남녀 모두에서 PP는 50대 이후 가파르게 증가하였다. 남자의 경우 특히 50대 이후의 연령과 관계한 혈압의 증가는 큰동맥의 굳어짐 현상이 가장 큰 공헌을 하는 것으로 보이며, 여성의 경우는 큰동맥굳어짐, 일회심박출량 또는 심실박출율과 같은 다양한 원인에 기인하는 것으로 평가된다. PP의 증가는 심장에 부담을 주게 되며 특히 50대 이후 남녀 모두에서 가파른 위험성이 예견된다. 이 연구에서는 남녀 모두에서 고혈압 발병률이 이전의 연구들에 비해 높게 나타나고 있다. 높은정상혈압을 고혈압 위험군에 포함시킨다면 고혈압 관리를 위한 대상자의 범위는 상당히 확장될 것으로 보인다.

Objectives: This study was conducted to investigate the relationship between heat-related illnesses developed in the summer of 2012 and temperature. Methods: The study analyzed data generated by a heat wave surveillance system operated by the Korea Centers for Disease Control and Prevention during the summer of 2012. The daily maximum temperature, average temperature, and maximum heat index were compared to identify the most suitable index for this study. A piecewise linear model was used to identify the threshold temperature and the relative risk (RR) above the threshold temperature according to patient characteristics and region. Results: The total number of patients during the 3 months was 975. Of the three temperature indicators, the daily maximum temperature showed the best goodness of fit with the model. The RR of the total patient incidence was 1.691 (1.641 to 1.743) per $1^{\circ}C$ after $31.2^{\circ}C$. The RR above the threshold temperature of women (1.822, 1.716 to 1.934) was greater than that of men (1.643, 1.587 to 1.701). The threshold temperature was the lowest in the age group of 20 to 64 ($30.4^{\circ}C$), and the RR was the highest in the ${\geq}65$ age group (1.863, 1.755 to 1.978). The threshold temperature of the provinces ($30.5^{\circ}C$) was lower than that of the metropolitan cities ($32.2^{\circ}C$). Metropolitan cities at higher latitudes had a greater RR than other cities at lower latitudes. Conclusions: The influences of temperature on heat-related illnesses vary according to gender, age, and region. A surveillance system and public health program should reflect these factors in their implementation.

Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a disorder characterized by the repetitive collapse of the pharyngeal airway during sleep, which leads to oxygen desaturation, sleep fragmentation, daytime sleepiness, and increased risk for hypertension and stroke. We investigated the clinical factors related to the severity of OSAHS. Polysomnography was performed in three hundred and ninety five consecutive adult patients with clinical symptoms of obstructive sleep apnea syndrome. All patients completed the sleep questionnaire and the Epworth Sleepiness Scale before polysomnography. Patients were classified into four groups based on the severity of their polysomnographic data: Non-OSA group, characterized by Apnea-Hypopnea Index (AHI) < 5; mild OSA group, by AHI 5-15; moderate OSA group, by AHI 16-30; and severe OSA group, by AHI > 30. Neck circumference was also measured at the cricothyroid level. A total of 395 patients (336 men and 59 women) were studied. In the non-OSA group, there were 55 patients; their mean neck circumference was $39.63{\pm}4.24cm$ and mean BMI was $24.48{\pm}3.53$. In the mild group, there were 101 patients; their mean neck circumference was $41.93{\pm}3.75cm$ and mean BMI was $25.33{\pm}2.94$. In the moderated group, there were 93 patients; their mean neck circumference was $43.27{\pm}3.50cm$ and BMI was $25.90{\pm}2.88$. In the severe group, there were 146 patients; their mean neck circumference was $44.94{\pm}3.93cm$ and mean BMI was $26.81{\pm}3.76$. Men had significantly larger neck circumference than women ($Mean{\pm}SD$, $43.72{\pm}3.83$ vs $39.17{\pm}4.30$, p < 0.001), and higher AHI than women ($29.12{\pm}22.65$ vs $14.63{\pm}14.11$, p < 0.001). Multiple regression analysis revealed that neck circumference was the most significant predictor of AHI. Neck circumference and BMI were positively correlated with the severity of OSAHS. The severity of OSAHS was greater in men than in women.

수면 무호흡을 포함한 다양한 원인의 수면과 관련된 호흡장애를 동반한 환자들에서는 여러가지 심혈관계 기능부전이 초래되어 이들 환자의 임상경과에 중대한 영향을 미친다. 수면 무호흡증후군, 특히 폐쇄성 수면 무호흡증후군은 수면장애의 여러 가지 원인 중 임상영역에서 가장 흔히 볼수 있는 질환으로 전신성 고혈압, 심부정맥, 폐동맥 고혈압 및 우심실 부전, 협심증 및 심근경색증, 뇌졸증등의 발병률이 정상인에 비하여 현저히 높은 것으로 알려져 있다. 폐쇄성 수면 무호흡과 달리 중추성 수면 무호흡은 수면중에 호흡중추를 불안정하게 하는 다양한 원인에 의해 발생하며 역시 심혈관계의 기능에 영향을 미칠 수 있다. 수면중에 환기장애가 더욱 악화될 수 있는 호흡기계 질환이 있는 환자들은 수면 무호흡증후군과 달리 만성적인 저산소증과 고탄산증이 동반되며 이로 인해 심부정맥, 폐동맥 고혈압, 우심실 부전(폐성심) 등의 심혈관계 이상이 초래될 수 있다. 따라서 수면 무호흡을 포함한 수면과 관련된 호홉 장애의 진단과 치료에 있어서는 호흡기계 질환에 대한 정확한 평가와 더불어 동반될 수 있는 심혈관계의 기능부전에 대한 정밀한 분석이 반드시 필요하며, 이들 자료를 바탕으로 기관절개술, 기계적 호흡, 지속적 양압공급치료, 적절한 산소요법 등의 적극적이고도 효과적인 치료법을 적용함으로서 심혈관계 합병증의 발생과 이로 인한 사망률을 감소시킬 수 있을 것으로 생각된다.

Background: To determine the predictors of clinical outcomes following surgical descending thoracic aortic (DTA) repair. Methods: We identified 103 patients (23 females; mean age, $64.1{\pm}12.3$ years) who underwent DTA replacement from 1999 to 2011 using either deep hypothermic circulatory arrest (44%) or partial cardiopulmonary bypass (CPB, 56%). Results: The early mortality rate was 4.9% (n=5). Early major complications occurred in 21 patients (20.3%), which included newly required hemodialysis (9.7%), low cardiac output syndrome (6.8%), pneumonia (7.8%), stroke (6.8%), and multi-organ failure (3.9%). None experienced paraplegia. During a median follow-up of 56.3 months (inter-quartile range, 23.1 to 85.1 months), there were 17 late deaths and one aortic reoperation. Overall survival at 5 and 10 years was $80.9%{\pm}4.3%$ and $71.7%{\pm}5.9%$, respectively. Reoperation-free survival at 5 and 10 years was $77.3%{\pm}4.8%$ and $70.2%{\pm}5.8%$. Multivariable analysis revealed that age (hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.05 to 1.15; p<0.001) and left ventricle (LV) function (HR, 0.88; 95% CI, 0.82 to 0.96; p<0.003) were significant and independent predictors of long-term mortality. CPB strategy, however, was not significantly related to mortality (p=0.49). Conclusion: Surgical DTA repair was practicable in terms of acceptable perioperative mortality/morbidity as well as favorable long-term survival. Age and LV function were risk factors for long-term mortality, irrespective of the CPB strategy.

Background: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. Methods: We conducted a multicenter, prospective, non-interventional study. Patients with $CHADS_2{\geq}1$ and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. Results: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had $CHADS_2{\geq}2$ and 83.6% had $CHA_2DS_2-VASc{\geq}2$. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. Conclusion: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.
