Abstract 10194: Declining Age-Adjusted Prevalence, Incidence and Recurrence Rates Of Hospitalized Atherothrombotic Vascular Disease in the Australian Population
Background. Understanding the current epidemiology of hospitalized atherothrombotic disease affecting the coronary, cerebral, and peripheral arteries is vital for prevention and health service planning. Hospitalization for atherothrombotic disease is projected to rise due to better survival and population ageing. We determined sex and age-standardized trends in the prevalence, incidence and recurrence of atherothrombotic events requiring hospitalization in an Australian state from 2000 to 2007.
Methods. Linked statewide records of hospitalizations for atherothrombotic disease were obtained from 1985 onwards. Sex and age-standardized (35-84 years) rates were derived using a 15-year lead-in to assess atherothrombotic disease.
Results. In 2007, 45,916 (8.6%) men and 22,782 (4.3%) women had atherothrombotic disease requiring hospital treatment. From 2000 to 2007 there were 58,656 incident (63.4% men) and 48,920 recurrent cases (68.8% men), dominated by coronary artery disease causing 63.8% of the incident and 78.1% of the recurrent events. The ratio of incident to recurrent events was 1.0 for coronary and peripheral arterial but 3.1 for cerebrovascular disease. The table shows the major trends.
Conclusion. This study is unique in comprehensively documenting the hospitalisation of atherothrombotic disease for a statewide population. Declining age-adjusted trends in the prevalence, incidence and recurrence rates of hospitalized atherothrombotic disease across the population are an indicator of better primary and secondary prevention. These trends are important for health care planning given the large burden of atherothrombotic disease and an ageing Australian population.
