  • Ambient air pollution (AAP) and particulate matters (PM) have been closely associated with adverse health effects such as respiratory disease and cardiovascular diseases. Previous studies have examined the adverse health effects associated with short- and long-term exposure to AAP and outdoor PM on respiratory disease. However, the effect of PM size ($PM_{2.5}$ and $PM_{10}$) on cardiovascular disease has not been well studied. Thus, it remains unclear how the size of the inhalable particles (coarse, fine, or ultrafine) affects mortality and morbidity. Airborne PM concentrations are commonly used for ambient air quality management worldwide, owing to the known effects on cardiorespiratory health. In this article, we assess the relationship between cardiovascular diseases and PM, with a particular focus on PM size. We discuss the association of $PM_{2.5}$ and $PM_{10}$, nitrogen dioxide ($NO_2$), and elemental carbon with mortality and morbidity due to cardiovascular diseases, stroke, and altered blood pressure, based on epidemiological studies. In addition, we provide evidence that the adverse health effects of AAP and PM are more pronounced among the elderly, children, and people with preexisting cardiovascular and respiratory conditions. Finally, we critically summarize the literature pertaining to cardiovascular diseases, including atherosclerosis and stroke, and introduce potential studies to better understand the health significance of AAP and PM on cardiovascular disease.

  • Purpose: The purpose of this study is to investigate cardiovascular risk factors, their interaction, degree of cardiovascular risk and to analyze the effects of related fcators in women workers. Method: A Survey was conducted in 529 employed women in 36 workplaces from October 25, 2002 to December 12, 2002. The survey was distributed and collected by occupational health nurses working at work sites. Result: The result were as followings; The female workers had about 2 cardiovascular risk factors. 82.1% were not exercising more than 3 times a week, 45.9% reported noise-exposure, 38.2% had higher perceived stress, 25.4% were shift-workers, 10.4% were long-time workers(over 60hour/week), 4.4% were frequent drinker, 3.9% were current smokers. The rate of obesity in measured as BMI greater than 25 was 4.0%. Many cardiovascular risk factors were correlated. Job-related and health behavior-related cardiovascular risk factors were correlated statistically. Expose to noise, reported perceived stress were powerful predictors in their degree of cardiovascular risk. Conclusion; Based on the results of this study, cardiovascular prevention programs for women in workplace should be designed as a multifactorial approach, which include stress management and job-related risk factor management as essential components to be effective in addressing the needs of the population.

  • Background: Many studies have explained regional disparities in health by socioeconomic status and healthcare resources, focusing on differences between urban and rural area. However some cities in Korea have the highest cardiovascular mortality, even though they have sufficient healthcare resources. So this study aims to confirm three hypotheses. (1) There are also regional health disparities between cities not only between urban and rural area. (2) It has different regional risk factors affecting cardiovascular mortality whether it is urban or rural area. (3) Besides socioeconomic and healthcare resources factors, there are remnant factors that affect regional cardiovascular mortality such as health behavior and physical environment. Methods: The subject of this study is 227 local authorities (si, gun, and gu). They were categorized into city (gu and si consisting of urban area) and non-city (gun consisting of rural area), and the city group was subdivided into 3 parts to reflect relative different city status: city 1 (Seoul, Gyeonggi cities), city 2 (Gwangyeoksi cities), and city 3 (other cities). We compared their mortalities among four groups by using analysis of variance analysis. And we explored what had contributed to it in whole authorities, city and non-city group by using multiple regression analysis. Results: Cardiovascular mortality is highest in city 2 group, lowest in city 1 group and middle in non-city group. Socioeconomic status and current smoking significantly increase mortality regardless of group. Other than those things, in city, there are some factors associated with cardiovascular mortality: walking practice(-), weight control attempt(-), deficiency of sports facilities(+), and high rate of factory lot(+). In non-city, there are other factors different from those of city: obesity prevalence(+), self-perceiving obesity(-), number of public health institutions(-), and road ratio(-). Conclusion: To reduce cardiovascular mortality and it's regional disparities, we need to consider differentiated approach, respecting regional character and different risk factors. Also, it is crucial to strengthen local government's capacity for practicing community health policy.

  • We report the case of a patient with penetrating chest trauma (right chest) who had undergone a left pneumonectomy due to pulmonary tuberculosis 24 years ago. We performed an emergent thoracotomy, finding an opening of the penetrating wound in a lower-lobe basal segment of the right lung. A stapled tractotomy was performed along the tract. Bleeding control and air-leakage control was done easily and rapidly. The patient was discharged without any complications on the seventh day of admission. Tractotomy can be a good option for treating penetrating lung injuries in patients with limited lung function who need emergent surgery.

  • Objectives: The aim of this study was to evaluate the effects of a lifestyle modification program for Korean adults with cardiovascular disease risk factors on their health behaviors and health status. Methods: A total of 448 adults with abdominal obesity and additional cardiovascular disease risk factors(high blood pressure, low HDL-cholesterol, high triglyceride or high blood glucose) were randomly assigned to either an intensive intervention group (IIG, n=216) or a minimal intervention group(MIG, n=232). Participants in the IIG received lifestyle modification program which consisted of health counseling with nutrition assessment, health booklet and health diary, while those in MIG received minimal information. Results: The participants in the IIG significantly improved dietary habits(p<.05), retrained eating(p<.001), external eating(p<.01) behaviors, leisure time physical activity(p<.05), dietary self-efficacy(p<.01), exercise self-efficacy(p<.01) and MetS score(p<.001) after 3 months. In addition, the participants in the IIG showed more improvement in dietary habits(p<.05) compared with those in the MIG. Conclusion: The lifestyle modification program was effective in improving some health behaviors, behavioral determinants and cardiovascular risk factors for a short term.

  • Objectives Numerous studies have revealed the adverse health effects of acute and chronic exposure to particulate matter less than $10{\mu}m$ in aerodynamic diameter ($PM_{10}$). The aim of the present study was to examine the spatial distribution of $PM_{10}$ concentrations and cardiovascular mortality and to investigate the spatial correlation between $PM_{10}$ and cardiovascular mortality using spatial scan statistic (SaTScan) and a regression model. Methods From 2008 to 2010, the spatial distribution of $PM_{10}$ in the Seoul metropolitan area was examined via kriging. In addition, a group of cardiovascular mortality cases was analyzed using SaTScan-based cluster exploration. Geographically weighted regression (GWR) was applied to investigate the correlation between $PM_{10}$ concentrations and cardiovascular mortality. Results An examination of the regional distribution of the cardiovascular mortality was higher in provincial districts (gu) belonging to Incheon and the northern part of Gyeonggi-do than in other regions. In a comparison of $PM_{10}$ concentrations and mortality cluster (MC) regions, all those belonging to MC 1 and MC 2 were found to belong to particulate matter (PM) 1 and PM 2 with high concentrations of air pollutants. In addition, the GWR showed that $PM_{10}$ has a statistically significant relation to cardiovascular mortality. Conclusions To investigate the relation between air pollution and health impact, spatial analyses can be utilized based on kriging, cluster exploration, and GWR for a more systematic and quantitative analysis. It has been proven that cardiovascular mortality is spatially related to the concentration of $PM_{10}$.

  • An index was developed that estimates cardiovascular health degree with easily available physiological information such as survey and noninvasive measurement. The survey score was calculated by utilizing questions related to personal disease history, self-feeling, and management state. The measurement score was calculated using physiological parameters such as blood pressure, accelerated plethysmograph(APG), and heart rate variability(HRV), and augmentation index(AI). In order to evaluate effectiveness of the cardiovascular index and modify weighting factors used in each item, a clinical trial was done in a general hospital. The cardiovascular index showed a clear correlation of 0.685 with the doctor's score on the cardiovascular health degree. The correlation between the self-estimated score and doctor's score was as low as 0.217. The large gap between these two scores demonstrated necessity of more objective tools like the cardiovascular index. The cardiovascular score showed a significant difference between normal persons and patients suffering hypertension or diabetes. (p=0.000).

  • Background: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. Methods: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. Results: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderate-intensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisure-time physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. Conclusion: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

  • Purpose: This study aimed to comprehensively examine middle-aged male taxi drivers' perceptions of the risk of cardiovascular disease. Methods: A qualitative method was used, with focus group interviews. The participants were middle-aged male taxi drivers who had been driving for more than ten years and for more than six hours daily. Results: The data were analyzed using qualitative thematic analysis. Middle-aged male taxi drivers' perceptions of the risk of cardiovascular disease were categorized into three main themes: "individual perceptions of cardiovascular disease", "possibility of behaviors for cardiovascular disease" and "motivations of behaviors for cardiovascular disease". Six sub-themes were extracted as follows: "perception of vulnerability", "perception of seriousness", "perception of profitability", "perception of disability", "self-awareness" and "advancing toward health care". Conclusion: It is necessary to invigorate support systems through measures including education, counseling, and web-based programs to prevent cardiovascular disease in middle-aged male taxi drivers.

  • Background: Survival of children experiencing cardiac arrest refractory to conventional cardiopulmonary resuscitation (CPR) is very poor. We sought to examine current era outcomes of extracorporeal CPR (ECPR) support for refractory arrest. Methods: Patients who were <18 years and underwent ECPR between November 2013 and January 2016 were including in this study. We retrospectively investigated patient medical records. Results: Twelve children, median age 6.6 months (range, 1 day to 11.7 years), required ECPR. patients' diseases spanned several categories: congenital heart disease (n=5), myocarditis (n=2), respiratory failure (n=2), septic shock (n=1), trauma (n=1), and post-cardiotomy arrest (n=1). Cannulation sites included the neck (n=8), chest (n=3), and neck to chest conversion (n=1). Median duration of extracorporeal membrane oxygenation was five days (range, 0 to 14 days). Extracorporeal membrane oxygenation was successfully discontinued in 10 (83.3%) patients. Nine patients (75%) survived more than seven days after support discontinuation and four patients (33.3%) survived and were discharged. Causes of death included ischemic brain injury (n=4), sepsis (n=3), and gastrointestinal bleeding (n=1). Conclusion: ECPR plays a valuable role in children experiencing refractory cardiac arrest. The weaning rate is acceptable; however, survival is related to other organ dysfunction and the severity of ischemic brain injury. ECPR prior to the emergence of end-organ injury and prevention of neurologic injury might enhance survival.
