Objectives: This study aimed to analyze the mortality of heart disease (HD), ischemic heart disease (IHD), and cerebrovascular disease (CeVD) through an age-period-cohort (APC) analysis. Methods: We used data on mortality due to cardiovascular disease from 1995 to 2018 in Japan, as determined by Vital Statistics. Age groups from 0 years to 99 years were defined by 5-year increments, and cohorts were defined for each age group of each year with a 1-year shift. We used Bayesian APC analysis to decompose the changes in the diseases' mortality rates into age, period, and cohort effects. Results: The period effects for all diseases decreased during the analyzed periods for both men and women. The cohort effects for men increased substantially in cohorts born from around 1940 to the 1970s for all types of cardiovascular diseases. The cohort effects of HD decreased in the cohorts born in the 1970s or later for both men and women. Regarding IHD and CeVD, either a non-increase or decrease of cohort effects was confirmed for cohorts born in the 1970s or later for men, but the effects for women showed a continuously increasing trend in the cohorts born in the 1960s or later. Conclusions: The cohort effects for IHD and CeVD showed increasing trends in younger generations of women. This suggests that preventive approaches against cardiovascular diseases are needed, particularly for women.

BACKGROUND: In patients with acute heart failure (AHF), diastolic dysfunction, especially pseudonormal (PN) or restrictive filling pattern (RFP) of left ventricle (LV), is considered to be implicated in a poor prognosis. However, prognostic significance of diastolic dysfunction in patients with ischemic heart disease (IHD) has been rarely investigated in Korea. METHODS: We enrolled 138 patients with IHD presenting as AHF and sinus rhythm during echocardiographic study. Diastolic dysfunction of LV was graded as ${\geq}2$ (group 1) or 1 (group 2) according to usual algorithm using E/A ratio and deceleration time of mitral inflow, E'/A' ratio of tissue Doppler echocardiography and left atrial size. RESULTS: Patients in group 1 showed higher 2-year mortality rate ($36.2%{\pm}6.7%$) than those in group 2 ($13.6%{\pm}4.5%$; p = 0.008). Two-year mortality rate of patient with LV ejection fraction (LVEF) < 40% ($26.8%{\pm}6.0%$) was not different from those with LVEF 40%-49% ($28.0%{\pm}8.0%$) or ${\geq}50%$ ($13.7%{\pm}7.4%$; p = 0.442). On univariate analysis, PN or RFP of LV, higher stage of chronic kidney disease (CKD) and higher New York Heart Association (NYHA) functional class were poor prognostic factors, but LVEF or older age ${\geq}75$ years did not predict 2-year mortality. On multivariate analysis, PN or RFP of LV (hazard ratio [HR], 2.52; 95% confidence interval [CI], 1.09-5.84; p = 0.031), higher stage of CKD (HR, 1.57; 95% CI, 1.14-2.17; p = 0.006) and higher NYHA functional class (HR, 1.81; 95% CI, 1.11-2.94; p = 0.017) were still significant prognostic factors for 2-year mortality. CONCLUSIONS: PN or RFP of LV was a more useful prognostic factor for long-term mortality than LVEF in patients with IHD presenting as AHF.

Background: Patients with cardiovascular risks are recommended to use statins and antiplatelet agents to prevent major cerebro-cardiovascular events (MACCE). Antiplatelet agents also possess anti-inflammatory and antioxidant effects, in addition to their inhibitory activity on platelets. The differences in clinical outcomes in ischemic heart disease (IHD) based on the type of antiplatelet therapy combined with statin treatment were investigated in this study. Methods: We conducted a retrospective cohort study using electronic medical records of IHD patients from January 2010 to December 2014 at Ajou University Hospital. Patients on combination therapy of antiplatelet drugs and statins were grouped based on antiplatelet drug types: clopidogrel, cilostazol, or sarpogrelate. Propensity score matching was applied to balance the baseline of the groups of clopidogrel vs. cilostazol and the groups of clopidogrel vs. sarpogrelate. The incidence and risk of MACCE as primary outcomes were assessed between the groups of antiplatelet drugs. Results: Among the approximately 128,500 patients with IHD, 1,049 patients had taken a combination therapy of statin and antiplatelet agents. The cohorts of patients administered clopidogrel, cilostazol, or sarpogrelate were 906, 79, and 64, respectively. The incidence of MACCE was not significantly different among the cohorts (p=0.58), and there were no differences between clopidogrel vs. cilostazol (p=0.72) or clopidogrel vs. sarpogrelate (p=1.00) after propensity score matching. Conclusion: There was no difference in the incidence of MACCE based on the type of antiplatelet drug (clopidogrel, cilostazol, or sarpogrelate) in combination with a statin in patients with IHD.

The purpose of this study was to investigate the association of obesity with medical care use and costs according to overall diseases, cerebrovascular diseases (CVD), ischemic heart disease (IHD), hypertension (HTN) and diabetes mellitus (DM). The final sample was a group of persons who were free of diseases mentioned above and were not underweight. Their baseline screening program data and health insurance contribution data were connected with a 7-year medical claim database. The participants were classified according to their baseline BMI into normal, overweight, obese, and severely obese groups. Given the disease type, the total costs of DM showed the largest difference in each obesity group in both males and females. Also, the pharmacy costs for DM were more relevant than any other type of service to the obesity level. Considering the high prevalence of obesity and the relevantly increased medical care use and costs, there is a need for reduction in medical costs through obesity prevention efforts.

A majority of the peoples in Indian cities depend on high fat diet, smoking, ghutka chewing and improper sleep, these all are lifestyle changes, can cause ischemic heart disease. Globally, ischemic heart disease (IHD) is the leading killer. Unani System of medicine not only provides well-based medical cures for diseases, but its holistic approaches as it possess unique principles of diet, lifestyle and particularly therapeutics, to balance and enrich all aspects of physiology and psyche. All diseases are the result of poor management of the six governing (or essential) factors, beyond the ability of physics or Tabiat to maintain and restore homeostasis. In this context, lifestyle diseases can be prevented by conscious changes to the person's diet, behavior and environment. The holistic approach of Unani medicine is well placed to cover the two main pillars of lifestyle diseases, namely, prevention and treatment. In this paper, we report on the prevalence of CAD in patients with known diagnosis of CAD and try to find out its relationship with different lifestyle changes.

This study was designed to determine the outcomes of the team-based cardiac rehabilitation programs for patients with Ischemic Heart Disease(IHD) on their level of health behavior performance, anxiety, and quality of life. A total of 19 in-patients with IHD who have had PTCA treatment at G.Hospital in Inchon were selected as subject to data collection from 1 May 1998 to 30 Oct. 1998. The experimental group, consisting of 11 patients participated in the Hospital's cardiac rehabilitation program was compared with the non-rehabilitation control group of 8 patients. The experimental group has been trained on the cardiac rehabliltation programfor 120-150minute during hospitalization by a team consisted of four specialists, those are cardiologist, head nurse, dietian, and the author. Also individual follow-up training and interview were performed for the members of experimental group at their every visit to the Hospital after discharge. For all subjects, scores on health behavior performance, anxiety, and quality of life were collected two days and 12 weeks after PTCA treatment by questionnaire. The collected data were analyzed with the SPSS. The results of this study were summarized as follows : 1) The experimental group shows significant increase in health behavior performance score compared to the control group(-2.27, p=.022). 2) There was no significant difference between two group's anxiety scores (-.24, p= .803) and quality of life scores(-1.86, p= .061). 3) The correlation between health behavior performance and anxiety ( .07, p= .771), and that between health behavior performance and quality of life( .12, p= .621) respectively were not significant statistically. But the correlation between anxiety and quality of life were significant reversely ( .49, p= .032).

Background: Rheumatoid arthritis (RA) is a systemic inflammatory disease that manifests as joint damage or athletic disability via sustained inflammation of the synovial membrane. The risk of cardiovascular disease (CVD) is higher in RA patients. This study aimed at evaluating the association between CVD comorbidities and RA by comparing a pharmacotherapy group with a non-pharmacotherapy group. Methods: Patient sample data from the Health Insurance Review and Assessment Service (HIRA-NPS-2016) were used. Inverse probability of treatment weighting (IPTW) using the propensity score was used to minimize the differences in patient characteristics. Logistic regression analysis was used to evaluate the risk of CVD comorbidities. Results: The analyses included 1,207,213 patients, of which 33,122 (2.8%) had RA. The odds ratios (OR) of CVD comorbidities were increased in RA patients; ischemic heart disease (IHD: OR 1.75; 95% CI 1.73, 1.77), cerebral infarction (CERI: OR 1.28; 95% CI 1.26, 1.30), hypertension (HTN: OR 1.44; 95% CI 1.43, 1.45), diabetes mellitus (DM: OR 2.04; 95% CI 2.03, 2.06), and dyslipidemia (DL: OR 3.49; 95% CI 3.47, 3.51). The ORs of IHD, CERI, HTN, and DM in the traditional DMARD and biologic treatment groups were decreased, compared with those in the non-pharmacotherapy group. Conclusions: Thus, CVD risk was higher in RA patients, considering age, sex, and socioeconomic status. Appropriate pharmacotherapy could decrease the risk of CVD comorbidities in RA patients.

Since the 1960s, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westenization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged $30\sim64$ years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows ; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except $55\sim64$ age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more t]fan 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemia heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.

Plasma carotenoid levels were compared among 64 healthy male subjects (control) and 38 patients of ischemic heart disease(IHD) and 20 ones of cerebral infarction(CI) all of whom were over 50years of age. Another 98 healthy male subjects aged 23 to 58 were selected to compare their plasma carotenoid levels by age groups, Levels of lutein ,zeaxanthin and crpytoxanthin were lower in IHD(34$\pm$2, 13$\pm$1 and 62$\pm$7$\mu g$/dl)and CI(36$\pm$3, 12$\pm$2 and 41$\pm$6$\mu g$/dl)patient groups than in control group (84$\pm$5, 16$\pm$2 and 69$\pm$3$\mu\textrm{g}$/dl) while those of lycopene, $\alpha$-and $\beta$-carotene varied little among the three groups. The sum of the six carotenoid levels were levels were, therefore,highest(205$\pm$14$\mu\textrm{g}$/dl) in the control group followed by IHD(155$\pm$15$\mu g$/dl) and CI(128$\pm$17$\mu g$/dl) patient groups, Among the 98 healthy male subject for the age group study, levels of the three major carotenoids increased with age from the twenties to the fifities ; lutein, from 64$\pm$6 to 89$\pm$8$\mu g$/dl, cryptoxanthin, 57$\pm$8 to 73$\pm$4$\mu\textrm{g}$/dl and $\beta$-carotene were more significantly correlated(r=0.30 to 0.61, p<0.01), whereas levels of lycopene and $\alpha$-caroteme were significantly(r=0.21 - 0.23, p<0.05) correlated.

In addition to cellular damage, ischemia-reperfusion (IR) injury induces substantial damage to the mitochondria and endoplasmic reticulum. In this study, we sought to determine whether impaired mitochondrial function owing to IR could be restored by transplanting mitochondria into the heart under ex vivo IR states. Additionally, we aimed to provide preliminary results to inform therapeutic options for ischemic heart disease (IHD). Healthy mitochondria isolated from autologous gluteus maximus muscle were transplanted into the hearts of Sprague-Dawley rats damaged by IR using the Langendorff system, and the heart rate and oxygen consumption capacity of the mitochondria were measured to confirm whether heart function was restored. In addition, relative expression levels were measured to identify the genes related to IR injury. Mitochondrial oxygen consumption capacity was found to be lower in the IR group than in the group that underwent mitochondrial transplantation after IR injury (p < 0.05), and the control group showed a tendency toward increased oxygen consumption capacity compared with the IR group. Among the genes related to fatty acid metabolism, Cpt1b (p < 0.05) and Fads1 (p < 0.01) showed significant expression in the following order: IR group, IR + transplantation group, and control group. These results suggest that mitochondrial transplantation protects the heart from IR damage and may be feasible as a therapeutic option for IHD.
