To examine trends in ischaemic heart disease (IHD) incidence and prevalence in New Zealand from 2005 to 2016, using comprehensive linked national hospitalization and mortality data as proxy measures of all significant events.
Incident and prevalent cases of IHD in people aged ≥25 years were identified using individual patient-linkage of routinely collected ICD-10-coded hospitalization and mortality data. Incidence rates and prevalence proportions were calculated by sex and age group and then age-standardized to the 2016 New Zealand population. Ischaemic heart disease incidence and prevalence declined in men and women in all age groups. The average annual rate of decline in age-standardized IHD incidence was 3.3% for women and 2.7% for men, and the rate of decline in age-standardized IHD prevalence was 3.2% for women and 2.2% for men. Despite a 17% increase in the New Zealand population aged 25 years and over during the study period, the total number of people living with IHD also decreased, particularly in those aged 65 years and older.
In contrast to observations from other countries, where IHD incidence but not IHD prevalence has been falling, declining IHD incidence in New Zealand in recent decades is now mirrored by declining IHD prevalence.
利用综合的全国住院和死亡率数据作为所有重大事件的替代指标，检查新西兰 2005 年至 2016 年缺血性心脏病（IHD）发病率和患病率的趋势。
使用常规收集的 ICD-10 编码住院和死亡率数据对年龄≥25 岁的人群进行 IHD 发病和现患病例的个体患者链接识别。按性别和年龄组计算发病率和患病率，并根据 2016 年新西兰人口进行年龄标准化。IHD 的发病率和患病率在所有年龄组的男性和女性中均下降。女性年龄标准化 IHD 发病率的平均年下降率为 3.3%，男性为 2.7%，女性年龄标准化 IHD 患病率的下降率为 3.2%，男性为 2.2%。尽管在研究期间，25 岁及以上的新西兰人口增加了 17%，但患有 IHD 的总人数也有所减少，尤其是 65 岁及以上的人群。
与其他国家的观察结果相反，IHD 的发病率而非患病率一直在下降，新西兰最近几十年来 IHD 发病率的下降现在与 IHD 患病率的下降相吻合。
