Background:Large earthquakes have been associated with cardiovascular disease (CVD) mortality. In Japan, the 1995 Great Hanshin-Awaji (H-A) Earthquake was an urban-underground-type earthquake, whereas the 2011 Great East Japan (GEJ) Earthquake was an ocean-trench type. In the present study, we examined how these different earthquake types affected CVD mortality.Methods and Results:We examined death certificate data from 2008 to 2012 for 131 municipalities in Iwate, Miyagi, and Fukushima prefectures (n=320,348) and from 1992 to 1996 for 220 municipalities in Hyogo, Osaka, and Kyoto prefectures (n=592,670). A Poisson regression model showed significant increases in the monthly numbers of acute myocardial infarction (AMI)-related deaths (incident rate ratio [IRR] GEJ=1.34, P=0.001; IRR of H-A=1.57, P<0.001) and stroke-related deaths (IRR of GEJ=1.42, P<0.001; IRR of H-A=1.33, P<0.001) after the earthquakes. Two months after the earthquakes, AMI deaths remained significant only for H-A (IRR=1.13, P=0.029). When analyzing the standardized mortality ratio (SMR) after the earthquakes using the Cochran-Armitage trend test, seismic intensity was significantly associated with AMI mortality for 2 weeks after both the GEJ (P for trend=0.089) and H-A earthquakes (P for trend=0.005).Conclusions:Following the GEJ and H-A earthquakes, there was a sharp increase in CVD mortality. The effect of the disaster was sustained for months after the H-A earthquake, but was diminished after the GEJ Earthquake. (Circ J 2015; 79: 1000–1008)

Background: Cytochrome P450 (CYP) 2C19 polymorphism is associated with reduced responsiveness to clopidogrel and poor clinical outcome after drug-eluting stent (DES) implantation, but its contribution to lesion outcome after DES implantation is unclear. Methods and Results: The study included 160 Japanese patients who received clopidogrel and underwent DES implantation with follow-up angiography. Patients were divided into 3 groups by CYP2C19 polymorphism: extensive metabolizers (EM), intermediate metabolizers (IM), and poor metabolizers (PM). The incidence of major adverse cardiac events (MACE) and target lesion revascularization (TLR) were compared among the 3 groups. Optical coherence tomography (OCT) was performed for 120 patients to evaluate the incidence of intra-stent thrombi. Of the 160 patients, the proportion of EM, IM, and PM was 37.5%, 48.1%, and 14.4%, respectively. The incidence of TLR and MACE was more frequent in IM and PM than EM (TLR: 18.2% and 26.1% vs. 3.3%, P=0.008, MACE: 22.1% and 30.4% vs. 5.0%, P=0.005). Among the 120 patients who underwent follow-up OCT, intra-stent thrombi were more frequently detected in IM and PM than in EM (45.6% and 63.2% vs. 20.5%, P=0.005). The incidence of TLR was significantly higher in patients with than in those without intra-stent thrombi (27.7% vs. 6.8%, P=0.003). Conclusions: CYP2C19 loss-of-function polymorphism might be associated with the incidence of MACE and TLR in association with intra-stent thrombi.  (Circ J 2012; 76: 2348–2355)

Background:Adverse effects of dietary intake of trans-fatty acids (TFA) on the incidence of coronary artery disease (CAD) are well recognized in Western countries. The risk of TFA, however, has not been well clarified in Japan. We investigated the association of serum TFA concentration with serum lipid profile, coronary risk factors, and prevalence of CAD.Methods and Results:A total of 902 patients, who were hospitalized at Kobe University Hospital from July 2008 to March 2012 and gave written informed consent, were enrolled in this study. Among them, 463 patients had CAD, and 318 patients had metabolic syndrome (MetS). Serum TFA, elaidic acid (trans-9-C18:1) and linolelaidic acid (trans-9, 12-C18:2), were measured on gas chromatography/mass spectrometry. Serum TFA level had a positive correlation with body mass index, waist circumference, low-density lipoprotein cholesterol, triglycerides, and apolipoprotein B48, and an inverse correlation with age and high-density lipoprotein cholesterol. Fasting serum TFA, by age quartile in the young generation with CAD and/or MetS, was higher than that in patients without CAD and/or MetS. On multivariate logistic regression, TFA was identified as a CAD risk after adjustment for classical risk factors.Conclusions:Serum TFA concentration was elevated in young patients with CAD and/or MetS. Diet-derived TFA may cause a serious health problem, particularly in the young generation in Japan.
