OBJECTIVE To examine the relation between trends over time in mortality and hospital morbidity caused by various cardiovascular diseases in the Netherlands.
DESIGN Trend analysis by Poisson regression of national data on mortality and hospital admissions from 1975 to 1995.
SUBJECTS The Dutch population.
RESULTS All cardiovascular diseases combined were responsible for 39% of all deaths and 16% of all hospital admissions in 1995. From 1975 to 1995, age adjusted cardiovascular mortality declined by an annual change of −2.0% (95% confidence intervals (CI) −2.1% to −1.9%), while in the same period age adjusted discharge rates increased annually by 1.3% (95% CI 1.1% to 1.5%). Around 60% of the gain in life expectancy in this period was related to lower cardiovascular mortality. For mortality, major reductions were seen in coronary heart disease (annual change −2.9%) and in stroke (−2.1%), whereas the increase in hospital admissions was mainly caused by chronic manifestations of coronary heart disease (5.1%), heart failure (2.1%), and diseases of the arteries (1.8%). In recent years, the gap between men and women at risk of dying from coronary heart disease became smaller for those aged ⩽ 65 years.
CONCLUSIONS Our findings of a decrease in cardiovascular mortality and an increase in admission rates for chronic conditions such as heart failure, chronic coronary syndromes, and diseases of the arteries, support the hypothesis that the longer survival of many patients with heart diseases is leading to a growing pool of patients at increased risk for subsequent cardiovascular complications in Western countries.
