Objectives: This study was conducted to evaluate the effectiveness of the combination therapy of Saengmaek-san decoction and Western medicine on heart failure. Methods: A search was conducted on June 22, 2024 using keywords such as "heart failure", "saengmaeksan", and "shengmaisan". A meta-analysis was conducted according to the outcome measurements such as the total effective rate (TER), serum B-type natriuretic peptide (BNP), echocardiography results (left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), stroke volume (SV)), and six-minute walk test (6MWT). Data analysis was performed using the RevMan 5.4.1 software, and Cochrane's risk of bias (ROB) was used to assess the quality of the papers. Results: A total of eight randomized control trials were selected. The treatment group combining Saengmaek-san and Western medicine showed significant improvement effects in terms of TER, BNP, LVEF, LVESD, LVEDD, SV, and 6MWT compared to the control group using Western medicine alone [TER] RR=1.23, 95% CI: 1.13-1.34, p<0.00001; [BNP] MD=-206.14, 95% CI : -257.49--154.79, p<0.00001; [LVEF] MD=6.40, 95% CI : 5.54-7.27, p<0.00001; [LVEDD] MD=-6.55, 95% CI : -7.24--5.85, p<0.00001; [LVESD] MD=-3.07, 95% CI: -3.92--2.22, p<0.00001; [SV] MD=7.12, 95% CI : 5.73-8.50, p<0.00001; [6MWT] MD=43.69, 95% CI : 31.55-55.84, p<0.00001. Conclusion: This study suggests that the combination therapy of Saengmaek-san decoction and Western medicine is effective in treating heart failure. However, these findings should be interpreted cautiously due to the unknown or high risk of bias in the included trials.

Background and Objectives: Aortic valve replacement (AVR) is considered a class I indication for symptomatic severe aortic stenosis (AS). However, there is little evidence regarding the potential benefits of early AVR in symptomatic patients diagnosed with normal-flow, low-gradient (NFLG) severe AS. Methods: Two-hundred eighty-one patients diagnosed with symptomatic NFLG severe AS (stroke volume index ≥35 mL/m², mean transaortic pressure gradient <40 mmHg, peak transaortic velocity <4 m/s, and aortic valve area <1.0 cm²) between January 2010 and December 2020 were included in this retrospective study. After performing 1:1 propensity score matching, 121 patients aged 75.1±9.8 years (including 63 women) who underwent early AVR within 3 months after index echocardiography, were compared with 121 patients who received conservative care. The primary outcome was a composite of all-cause death and heart failure (HF) hospitalization. Results: During a median follow-up of 21.9 months, 48 primary outcomes (18 in the early AVR group and 30 in the conservative care group) occurred. The early AVR group demonstrated a significantly lower incidence of primary outcomes (hazard ratio [HR], 0.52; 95% confidence interval [CI], 0.29-0.93; p=0.028); specifically, there was no significant difference in all-cause death (HR, 0.51; 95% CI, 0.23-1.16; p=0.110), although the early AVR group showed a significantly lower incidence of hospitalization for HF (HR, 0.43; 95% CI, 0.19-0.95, p=0.037). Subgroup analyses supported the main findings. Conclusions: An early AVR strategy may be beneficial in reducing the risk of a composite outcome of death or hospitalization for HF in symptomatic patients with NFLG severe AS. Future randomized studies are required to validate and confirm our findings.

Hypertension is among the most common and important risk factors for stroke, heart attack, and heart failure which is considered to be the leading cause of death in Korea. The prevalence rate of hypertension in Korea is 27.9%, according to the 2006 Korea National Health and Nutrition Survey. Since non-pharmacologic nutrition education is recommended as the first step in the management of hypertension, evaluation of nutrition program is needed to form strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) for reducing the salt intake, at a public health center located in Gyunggi-province. The HNEP was offered for 16 weeks from May to September in 2007. Nutrition education activities included cooking classes, food preparation demonstrations, physical fitness programs, salty taste preference test sessions, games, case-study presentations, planning and evaluation of menus, etc. Forty patients participated fully in the program which had 47 female enrollees. Data about nutrient intake (24-hour recall), nutrition knowledge, food behavior were collected before (baseline) and after the program. Changes after program completion indicated the following: 1) diastolic blood pressure was decreased (p < 0.05), 2) sodium (salt) intake was also decreased (p < 0.01), especially baseline high salt intake group, 3) nutrition knowledge was improved (p<0.001), 4) dietary behaviors for maintaining a low salt diet was improved (p < 0.001), 5) participants preferred cooking class from nutrition education methods. As a conclusion, it appears that a nutrition education program for hypertensive female elderly for reducing the salt intake might effectively decrease blood pressure and salt intake. It also improves nutrition knowledge, dietary behavior, and finally adherence to a recommendable low-sodium diet.

Background: The integrated design of the HeartMate 3 (Abbott Laboratories, Chicago, IL, USA) affords flexibility to place the pump within the pericardium or thoracic cavity. We sought to determine whether the presence of a left ventricular assist device (LVAD) in either location has a meaningful impact on overall patient outcomes. Methods: A retrospective cohort study was conducted of all 165 patients who received a HeartMate 3 LVAD via a median sternotomy from November 2014 to August 2019 at our center. Based on operative reports and imaging, patients were divided into intrapleural (n=81) and intrapericardial (n=84) cohorts. The primary outcome of interest was in-hospital mortality, while secondary outcomes included postoperative complications, cumulative readmission incidence, and 3-year survival. Results: There were no significant between-group differences in baseline demographics, risk factors, or preoperative hemodynamics. The overall in-hospital mortality rate was 6%, with no significant difference between the cohorts (9% vs. 4%, p=0.20). There were no significant differences in the postoperative rates of right ventricular failure, kidney failure requiring hemodialysis, stroke, tracheostomy, or arrhythmias. Over 3 years, despite similar mortality rates, intrapleural patients had significantly more readmissions (n=180 vs. n=117, p<0.01) with the most common reason being infection (n=68/165), predominantly unrelated to the device. Intrapleural patients had significantly more infection-related readmissions, predominantly driven by non-ventricular assist device-related infections (p=0.02), with 41% of these due to respiratory infections compared with 28% of intrapericardial patients. Conclusion: Compared with intrapericardial placement, insertion of an intrapleural HM3 may be associated with a higher incidence of readmission, especially due to respiratory infection.

Following intracoronary stenting, antiplatelet therapy lead to greater protection from thrombotic complication. A few data are available about the effect of clopidogrel versus cilostazol, an antiplatelet commonly used after intracoronary stenting. To evaluate the efficacy and safety of clopidogrel plus aspirin compared with those of cilostazol plus aspirin in coronary stenting and to evaluate the efficacy of clopidogrel loading dose prior to coronary stealing in clopidogrel group. Data were retrospectively collected from medical charts of patients who had undergone coronary stenting and received either clopidogrel with or without loading 300 mg followed by 75 mg/d (n=58), or 200 mg/d cilostazol(n=72) for 1 year, between January 2000 and May 2002. All patients in both groups received aspirin 200 mg/d throughout the study. The primary endpoints at 7, 30, 180 and 365 days after stealing were the composite of death, Myocardial Infarction, stroke, angina, and revascularization in the intent to treat population and restenosis at follow up angiography. The secondary endpoints were the incidence of bleeding complications at 7, 30, and 365 days, and durg adverse effects at 365 days after stenting. At 180 and 365 days after stenting, the combined primary endpoints were significantly reduced in clopidogrel plus aspirin group (relative risk 0.39; 95% CI 0.17 to 0.92; p=0.021, RR 0.43; 95% CI 0.22 to 0.84; p=0.0085, respectively). However, the combined primary endpoints were not significantly different between the two groups at 7 and 30 days (p:1.00, p=0.79, respectively). Angiographic restenosis rate was 14.3% in clopidogrel plus aspirin uoup and 32.1% in cilostazol plus aspirin group (p=0.19). 300mg of clopidogrel loading dose did not significantly reduce the combined primary endpoints at 30 days after stenting (RR 0.14; 95% CI 0.01 to 2.65; p=0.23). The rate of bleeding complications and drug adverse effects were not different between the two groups. In patients undergoing intracoronary stenting, clopidogrel plus aspirin therapy is more beneficial than cilostazol plus aspirin in reducing major adverse cardiac events with similar rate of bleeding complication. A loading dose of clopidogrel did not lead to a statistically significant reduction in major adverse cardiac events.

배경: 관상동맥 우회술의 대동맥부 근위부 문합을 위한 상행 대동맥 부분 겸자는 대동맥 내벽에 존재하는 죽상반의 색전에 의한 뇌경색의 위험성을 높일 뿐 아니라, 겸자에 따른 직접적 대동맥 손상의 원인이 될 수 있다. Heartstring proximal sealing system (Guidant Corporation, Santa Clara, Calif)을 이용한 근위부 문합은 대동맥 부분 겸자를 피할 수 있어, 이러한 잠재적 위험을 방지할 수 있는 것으로 제시되어 왔다. 이 연구는 무심폐기 관상동맥 우회술의 근위부 문합에 있어서 대동맥 부분 겸자를 통한 수기 문합과 Heartstring system을 이용한 문합간의 수술 후 신경학적 합병증을 비교하고자 하였다. 대상 및 방법: 2003년 1월부터 2008년 8월까지 499명의 환자가 무심폐기 관상동맥 우회술을 시행받았다. 그 중 182명의 환자가 Heartstring system을 이용한 이식편 대동맥 근위부 문합술을 시행받았고(I군), 317명의 환자가 고식적 수기 문합술을 시행 받았다(II군). 이 두 군간의 수술 후 신경 손상을 비롯한 주요 합병증 및 사망율을 비교하였다. 결과: 나이, 성별, 좌심실 구출율, 신장 기능, 당뇨, 고혈압, 흡연력 등의 수술 전 인자들에 있어서 두 군간에 유의한 차이는 없었다. 수술 전 뇌허혈의 과거력은 환자는 두 그룹간에 유의한 차이가 없었으나(I군 31.3%, II군 34.4%, p=0.48), 뇌혈관 MRI상에서의 내경동맥의 협착이 75%가 넘는 환자는 I군이 81명(44.5%), II군이 95명으로(30.0%) 두 군간의 유의한 차이를 나타냈다(p=0.003). 수술 후 새로 발생한 신경 이상의 경우 I군에서 3명, II군에서 2명으로, 두 군간에 유의한 차이를 보이지 않았으나(p=0.258), I군의 경우 모두 일과성 허혈이었던 것에 반해 II군의 경우 모두 색전에 의한 다발성 뇌경색으로 나타났다. 그 외 수술 후 발생한 주요 합병증(p=0.47)및 사망(p=0.40)에 있어서 두 군간에 유의한 차이를 보이지 않았다. II군에서 한 명의 환자에서 수술 중 근위부 분합에 따른 대동맥 박리증이 발생하여 상행대동맥 치환술을 시행하였다. 결론: 비록 수술 후 신경학적 합병증의 빈도가 낮아 통계학적 유의성에 다다르진 못했으나, Heartstring system을 이용한 근위부 문합술은 고식적 문합에 비해 색전에 의한 수술 후 뇌졸중의 합병 및 대동맥 손상의 위험도를 낮출 것으로 기대해 본다.

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.

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.

배경 및 목적; 심폐체외순환의 부작용을 피하기 위해 최근 들어 심폐체외순환 없이 시행하는 관상동맥우회로술(Off pump CABG)이 시도되고 있다. 이 연구는 Off pump CABG와 심폐체외순환하에서 시행하는 관상동맥우회로술(On Pump CABG) 의 수술 전 위험요소와 수술 후 결과를 비교하였다. 방법; 2001년 1월부터 2001년 7월까지 CABG를 시행 받았던 178명중에서 판막수술이나 심실절제술 등 동반 수술이 없었던 166명을 대상으로 하였다. 이 중 Off Pump CABG환자는 52명이었고 On Pump CABG환자가 114명이었으며, 이 환자들을 대상으로 수술전 위험인자와 관상동맥 질환의 정도 및 수술 후 결과를 비교하였다. 결과; 두 군간의 연령, 남녀 비, 수술전 당뇨, 고혈압, 흡연력, 고지질증, 가족력 등 위험요소에 대한 통계적인 유의성은 없었으며, 폐쇄성 폐 질환이나 말초 동맥혈관 협착증 및 뇌경색의 기왕력, 심근경색의 기왕력이나 흉통의 정도(Canadian Class),관상동맥 질환의 정도 및 심박출계수도 통계적인 차이를 보이지 않았다. 수술시간은 Off Pump CABG에서 통계적으로 유의하게 짧았고(234 $\pm$ 37 min vs 290 $\pm$ 48 min, p<0.001), 이 식편수는 On Pump CABG에서 유의하게 많았다(3.4 $\pm$ 0.9개 vs 2.6 $\pm$ 0.8개, p<0.001). 수술 후 사망은 없었으며, 수술 후 측정한 CK-MB는 Off Pump CABG에서 통계적으로 유의하게 낮았고(10.1 $\pm$ 13.5 IU/L vs 33.1 $\pm$ 18.2 lU/L, p<0.001) 호흡기 사용시간도 통계적으로 유의하게 낮았다(14.8 $\pm$ 3.5 hours vs 16.2 $\pm$ 4.9 hours, p=0.048). 그 외 24시간 출혈량, 출혈로 인한 재수술, 중환자실 입원 기간, 수술 후 심근경색증, 감염, 신부전증, 신경과적 합병증 및 수술 후 입원 기간 등 수술 후 결과와 유병율에는 두 군간의 통계적 유의성이 없었다. 결론; Off Pump CABG는 On Pump CABG에 비해 수술시간의 단축과 수술 후 심근 손상의 정도가 낮고, 호흡기 사용시간이 짧게 나타났으나 On Pump CABG에 비해 이식편수가 적었다. 대체로 Off Pump CABG는 On Pump CABG에 비해 수술 후 결과에서 약간의 장점을 보여주었으나 Off Pump CABG의 장점을 알아보기 위해서는 더 많은 연구가 있어야 할 것으로 생각된다.
