Hypertension is the most powerful risk factor for stroke. Blood pressures (BP) measured out of clinic, such as self-measured BP at home and ambulatory BP are the better predictor of stroke than clinic BP. As well as higher 24-hr BP level, disruption of diurnal BP variation is also associated with increased risk for stroke. Recent prospective studies clearly demonstrated that the riser pattern with higher nocturnal BP than daytime BP and nocturnal hypertension per se are closely associated with cardiovascular death and cardiovascular events such as stroke and cardiac disease. The following pathological conditions are closely associated with this riser and non-dipper patter: increased circulating blood volume such as chronic kidney disease and congestive heart failure, autonomic nervous dysfunction such as diabetes particularly with neuropathy, and poor sleep quality such as sleep apnea syndrome. We have developed nocturnal hypoxia-triggered BP monitoring, and have detected marked midnight BP surges at the time of sleep apnea episodes. As the cardiovascular risk is increased in a sleep period in patients with obstructive sleep apnea, this surge may trigger the sleep-onset stroke. Considering that morning BP surge is the risk of stroke in a general population, the time of BP surge may be the time of increased cardiovascular risk. The perfect 24-hr BP control with diminishing exaggerated BP surge may achieve more effective prevention in stroke in hypertensive patients.<br>

欧米あるいはわが国における地域住民を対象としたさまざまなエビデンスから、JNC7において前高血圧(pre-hypertension)と定義された群の心血管あるいは脳血管イベントのリスク上昇が指摘されてきた。また地域住民を対象とした自治医科大学コホート研究においては、3分の1がpre-hypertensionであり、この群における規定因子は心血管イベントのハイリスクとされてきた肥満、脂質異常症、糖代謝異常によるものであったこと、また欧米と比較し、軽度の肥満であってもpre-hypertensionへの有意な関連があることを報告した。本稿では、わが国におけるpre-hypertensionの特徴を示し、この群へのハイリスクアプローチの必要性を解説する。(著者抄録)

INTRODUCTION: No epidemiological data exist concerning the influence of an earthquake on the risk of stroke. Whether the incidence of cerebrovascular stroke increased after the 1995 Hanshin-Awaji earthquake (EQ) in Japan and whether seismic intensity affected stroke risk dose-dependently was examined. METHODS: A retrospective cohort study was conducted among residents, who were living in two towns on the island of Awaji and were participants of the National Health Insurance (NHI) program. The two towns were divided into 11 districts and their respective damage and socioeconomic states were investigated. Reviewing the NHI documents issued before and after the EQ, people who had strokes (9th International Classification of Diseases, codes 430-431 or 433-434.9) were identified. Risk of stroke in relation to the seismic intensities, was assessed with the Cox proportional hazard model. RESULTS: Among subjects aged 40 to 99 years, 45 of 8,758 (0.514%) had a stroke the year before the EQ 72 of 8,893 (0.810%) had a stroke in the first year following the EQ, and 49 of 8,710 (0.566%) had a stroke in the second year following the EQ. In districts where the earthquake's intensity was < or = 9.5 on the modified Mercalli intensity (MMI), compared with the year prior to the EQ, the relative risk (RR) of stroke was 2.4 (95% confidence interval (CI) = 1.1, 5.0) in the first year following the EQ, after adjusting for age, gender, and income. In that year, compared with MMI of < 8.5-9.0, RRs for 9.0-9.5 and > or = 9.5 were 1.6 (CI = 0.9, 2.1) and 2.0 (CI = 1.1, 3.7), respectively (p for trend 0.02). No trend for the RR was observed in the year before the EQ or in the second year following the EQ. CONCLUSION: The incidence of stroke increased in the first year following the EQ. The increase was associated with seismic intensity in a dose-response manner. Results suggest a potential threshold for RR of > or = 2.0 in areas near 9.5 on the MMI scale.

Objective. We conducted a large-scale cross-sectional study to assess the prevalence of Chlamydia pneumoniae and clarify the association between seropositivity and risk factors, such as smoking status, physical activity and body mass index in Japanese rural districts. Methods. A total of 1,063 men and 1,573 women aged 18-94 years participated in 1999. Serum index values (ID) of IgA and IgG antibodies to C pneumoniae were measured by ELISA. Index values were categorized as "negative" (ID&lt 1.10), "positive" (ID ≧ 1.10) and "high positive" (ID ≧ 3.00). Logistic regression analysis was performed to estimate the crude and adjusted odds ratios for C. pneumoniae seropositivity. Results. The overall prevalence of C. pneumoniae IgA seropositivity was 52.5%, and that of IgG was 55.2%. Each seropositivity significantly increased with age. The prevalence among men was significantly higher than in women in C. pneumoniae IgG "high positive" subjects. Compared with never-smokers, the adjusted odds ratio of current smokers was 2.00 (95%CI: 1.45-2.77) for C. pneumoniae IgA seropositivity. The adjusted odds ratio of the higher tertiles of physical activity for C. pneumoniae IgG seropositivity was 1.42 (1.12-1.80) compared with the lower tertiles. In "high positive" subjects, smoking was associated with both immune complexes. Conclusion. We confirmed a high prevalence of C. pneumoniae seropositivity among healthy Japanese adults. The results indicated that smoking and high physical activity were associated with C. pneumoniae infection.

Increase of TAT is reflected by the generation of thrombin in hypercoagulable state. TAT might increase in DIC characterized by the formation of disseminated micro-thrombosis. DIC was classified into three groups according to the results of screening tests (FDP, platelet count, fibrinogen, prothrombin time). TAT values significantly increased in the stage of pre-DIC compared with the control group consisting of DIC prone underlying disease. Pre-DIC was easily detected by an increase of TAT during the clinical course. Management of high TAT began with the use of an anticoagulant such as heparin under the condition of sufficient ATIII level. The lowering effect of TAT was easily obtained by the anticoagulant. In ATIII-deficient DIC, the high TAT reduced with the substitution of ATIII concentrate, though a transient increase of TAT was found during the administration of ATIII. To reduce the high TAT under the deficient state of ATIII, MD805, a synthetic thrombin inhibitor, was introduced to avoid further consumption of ATIII. The TAT was decreased by the use of MD805 without administration of ATIII. MD805 could be used as an effective anticoagulant in high TAT due to DIC under an ATIII-deficient state. Although the TAT improved with an adequate anticoagulation in DIC, spontaneous bleeding sometimes appeared as a complication associated with the high level of alpha 2 plasmin inhibitor plasmin complex. In this case, the combined use of tranexamic acid relieved the bleeding.
