Trends in ischaemic heart disease hospitalisation and case fatality in the Hong Kong Chinese population 2000-2009: a secondary analysis.

Chau PH, Wong M, Woo J - BMJ Open (2013)

Bottom Line: Overall, the short-term/long-term case fatality rates were unchanged over time for both sexes.Hong Kong trends resembled those in the USA, England and Wales, showing stable or slow decline in the IHD rates, while increasing trends were observed for some age groups, particularly young adults.Public health promotion efforts should focus on reducing cardiovascular risk factors, such as hypertension prevalence.

ABSTRACT

Objectives: This study examines the recent trends in ischaemic heart disease (IHD) incidence and case fatality in Hong Kong and explores the possible risk factors.

Design: Retrospective observational study.

Setting: All public hospitals in Hong Kong.

Outcome measures: Incidence rate was defined as the number of IHD inpatient episodes divided by the size of the corresponding population. Short-term and long-term case fatality rate was defined as deaths from all causes occurring within 30 and 31-365 days, respectively, divided by the number of IHD inpatient episodes among the corresponding population.

Methods: Poisson and logistic regression models were used to examine the IHD incidence and short-term/long-term case fatality trends, respectively, for different age and sex groups.

Results: IHD incidence was stable in most age groups. However, the incidence in men aged 15-24, 35-44 and ≥85 years showed increasing trends, whereas the incidence in men aged 55-64 years and women aged 35-74 years showed decreasing trends. Overall, the short-term/long-term case fatality rates were unchanged over time for both sexes. Short-term case fatality showed increasing trends in women aged 65-74 and ≥85 years, while long-term case fatality in men aged 55-64 and 75-84 years and women aged ≥75 years showed increasing trends.

Conclusions: Hong Kong trends resembled those in the USA, England and Wales, showing stable or slow decline in the IHD rates, while increasing trends were observed for some age groups, particularly young adults. Public health promotion efforts should focus on reducing cardiovascular risk factors, such as hypertension prevalence.

BMJOPEN2013002963F1: (A and B) Age-sex-specific ischaemic heart disease (IHD) incidence rates among the population aged ≥15 years in Hong Kong for 2000–2009.

Mentions: The age-standardised IHD incidence rate (per 100 000 population) for men aged ≥15 years remained stable at 460.9 in 2000 and 477.9 in 2009, whereas that for women declined from 290.7 to 251.1 over the same time period (table 2). Figure 1 shows the age-sex-specific IHD incidence rates. Poisson regression analysis showed that the incidence rates of IHD increased significantly by 10.7% per year (95% CI 1.4% to 20.9%) among men aged 15–24 years, 2.2% per year (95% CI 1.0% to 3.4%) among men aged 35–44 years and 4.1% per year (95% CI 1.4% to 6.8%) among men aged ≥85 years, despite the overall stable trend. For women, the incidence rates decreased significantly by 3.0% per year (95% CI 0.5% to 5.4%) among those aged 35–44 years, 5.2% per year (95% CI 4.0% to 6.4%) among those aged 45–54 years, 6.7% per year (95% CI 5.1% to 8.4%) among those aged 55–64 years and 4.0% per year (95% CI 2.6% to 5.4%) among those aged 65–74 years, but remained stable for the youngest and oldest age groups. Table 3 provides a summary of the trends analysis.
