To elucidate the trends in stroke and myocardial infarction (MI) over 24 years in O City, Ehime Prefecture, Japan.
We conducted an annual survey of hospital-based disease registrations to determine the incidence and type of stroke (hemorrhagic stroke (HS) and ischemic stroke (IS)) and MI from 1996 to 2022. The numbers of deaths due to stroke and MI were determined using the electronic death certificate dataset provided by the Ministry of Health, Labour and Welfare. The number of deaths and incidences of stroke and MI in O City over 24 years were classified into four six-year periods: 1999-2004 (Period 1), 2005-2010 (Period 2), 2011-2016 (Period 3), and 2017-2022 (Period 4).
Age-adjusted death rates from stroke and IS decreased in both men and women, while those from HS remained unchanged. However, the age-adjusted incidence of stroke and IS in men and women decreased from Periods 1 to 2 but increased from Periods 2 to 4. In women, the age-adjusted incidence of HS increased from Periods 2 to 4, whereas in men, the incidence of HS remained unchanged. In both men and women, the age-adjusted death rate of MI decreased. In women, the age-adjusted incidence of MI decreased from Periods 1 to 4. The age-adjusted incidence of MI in men did not change over time.
For both men and women during the 24 years of follow-up, the age-adjusted death rates from stroke and MI decreased from Periods 1 to 4; however, the age-adjusted incidences of stroke and IS increased from Periods 2 to 4.
阐明日本爱媛县O市24年间中风和心肌梗死(MI)的发病趋势。
我们对基于医院的疾病登记进行了年度调查,以确定1996年至2022年中风(出血性中风(HS)和缺血性中风(IS))和MI的发病率及类型。使用厚生劳动省提供的电子死亡证明数据集确定中风和MI导致的死亡人数。O市24年间中风和MI的死亡人数及发病率被分为四个六年期:1999 - 2004年(第1期)、2005 - 2010年(第2期)、2011 - 2016年(第3期)和2017 - 2022年(第4期)。
中风和IS的年龄调整死亡率在男性和女性中均下降,而HS的年龄调整死亡率保持不变。然而,中风和IS的年龄调整发病率在男性和女性中从第1期到第2期下降,但从第2期到第4期上升。在女性中,HS的年龄调整发病率从第2期到第4期上升,而在男性中,HS的发病率保持不变。在男性和女性中,MI的年龄调整死亡率均下降。在女性中,MI的年龄调整发病率从第1期到第4期下降。男性中MI的年龄调整发病率随时间未发生变化。
在24年的随访期间,男性和女性中风和MI的年龄调整死亡率从第1期到第4期均下降;然而,中风和IS的年龄调整发病率从第2期到第4期上升。
