“…35,36 Regarding cardiovascular and cerebrovascular sudden death, it has been reported that in Japanese working population it occurred more frequently in April, when the new business year starts, compared to other months. 37 It was hypothesized that younger people in Japan might have to face greater occupational stress at the end of the old financial year and the beginning of the new year coinciding with winter and spring. 10,37 The quality of our registration system was assured by its completeness.…”

Background and Purpose-Seasonal variation in stroke incidence was examined using 14-year stroke registration data in a Japanese population. We also examined if this variation was modified by conventional stroke risk factors hypertension, diabetes mellitus, drinking, and smoking. Methods-Data were obtained from the Takashima Stroke Registry, which covers a stable population of Ϸ55 000 in Takashima County in central Japan. There were 1665 (men, 893; women, 772) registered first-ever stroke cases during 1988 to 2001. The average age of stroke onset for men and women patients was 69.4 and 74.2 years, respectively. Incidence rates (per 100 000 person-years) and 95% CI were calculated by gender, age, and stroke subtype for winter, spring, summer, and autumn. After stratifying patients by their risk factor history, the OR (with 95% CI) of having a stroke in autumn, winter, and spring were calculated, with summer serving as a reference. Results-Among the seasons, stroke incidence per 100 000 person-years was highest in the spring (231.3; 95% CI, 211.1 to 251.5). Spring incidence was highest in both men (240.8; 95% CI, 211.5 to 270.2) and women (222.1; 95% CI, 194.4 to 249.9), and in subjects younger than 65 years (72.6; 95% CI, 60.0 to 85.3) and 65 years or older (875.9; 95% CI, 787.5 to 964.3). Among stroke subtypes, spring incidence was highest for cerebral infarction (154.7; 95% CI, 138.2 to 171.2) and cerebral hemorrhage (53.7; 95% CI, 44.0 to 63.4). The spring excess in stroke incidence was observed regardless of the presence or absence of the risk factor histories. Conclusions-Stroke incidence appears to be highest in the spring among a Japanese population regardless of conventional risk factor history. Factors that explain this excess need further investigation. (Stroke. 2008;39:745-752.)

BackgroundThe factors that influence survival of out-of-hospital cardiac arrest in Japan have not been fully investigated. Methods and ResultsThe official emergency service record was used to investigate 1,600 patients for whom cardiopulmonary resuscitation was attempted by the city's emergency personnel. Only 45 (2.8%) patients survived for 1 month. The survival rate was 9.8% in the patients under 20 years of age, with a marked decreasing trend to 0.8% in the patients aged 80 years or older. The rate peaked at 4.8% on Sunday and bottomed out at 0.5% on Thursday, forming a distinct sine curve. The survival rate was 9.9% when an ambulance arrived at the scene within 4 min, with a steep drop to 2.5% when 4-7 min elapsed. However, the rate was not significantly different by the interval to hospital. Although bystander resuscitation did not significantly affect the survival, paramedics on board significantly improved the rate (3.5% vs 1.6%). Multivariate analysis confirmed that age, day of the week, place, interval to ambulance's arrival, and personnel on board were independently associated with the probability of survival. Conclusions Quick arrival of a paramedic team would improve the survival after out-of-hospital cardiac arrest. General education of lifesaving techniques would be another key factor.

Background: Sudden death has plagued mankind from time Immemorial. Clinical presentations include wide spectrum from symptom complex to completely asymptomatic. Sudden cardiac death in many cases, ‘first and only symptom. The high incidence, sudden, unexpected nature, combining with the low successful rate of resuscitation, make sudden cardiac deaths a major unsolved problem. Therefore, this study was conducted to illustrate etiolopathology, risk factors and triggers of sudden death with the expectation to provide new insight in epidemiological aspects of sudden death, which will help in care of patients, and prevention of premature cardiac deaths.Methods: A study of 50 cases of sudden death was conducted at tertiary care hospital. After evaluating detailed history from the family members, autopsy has been performed to find out cause of sudden death.Results: Principal culprit of sudden death is cardiovascular disease. Highest numbers of sudden death are in middle age group and having male preponderance might be due to presence of multiple risk factors, which have added or multiplicative effect. There are few autopsy negative cases, which are unexplained sudden death.Conclusions: Sudden and unexpected deaths in young population frequently become the subject of pathologic investigation to determine the cause of death.
