  • + Notes

    Only NSW residents are included. Rehabilitation episodes are excluded. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.

    A recent policy change (PD2017_015) resulted in patients treated solely within the emergency department being excluded from this indicator report. Please note that a minority of patients being managed in short stay areas of emergency departments are still included. Further information is found in a paper in the HealthStatsPLUS Methods tab on this website.

    Numbers for recent years include an estimate of the small number of hospitalisations of NSW residents in interstate public hospitals, data for which were unavailable at the time of production. Further details can be found in the Methods tab in the following HealthStats NSW indicator:

    The projections are extrapolations of age specific rates for each sex using Poisson regression models.

    Australian Bureau of Statistics estimated resident populations are based on the 2011 Census and are augmented with post-Census estimates; projected populations start from 2016. See Methods for details.

      The International Statistical Classification of Diseases and Related Health Problems

      National Centre for Classification in Health, Australia; AM - Australian Modification
      Description ICD-10 & ICD-10-AM Comments
      Circulatory disease (all) I00-I99, Excluding I84 All records are included except those involving rehabilitation, NSW residents only, all ages. 

      Episodes that are entirely within an emergency department are excluded.


      Transient ischaemic attacks (TIA) are a risk factor for strokes. TIA were classified as diseases of circulatory system in ICD-9-CM (with the exception of Amaurosis fugax, which has always been classified with nervous system group; ICD-9: 362.34, ICD10: G45.4). In ICD-10-AM, they are classified with the diseases of nervous system (G codes) and, consequently, are not included in the stroke count and in the total of diseases of circulatory system (i.e. cardiovascular diseases, I codes).

      Haemorrhoids were classified as diseases of the circulatory system under ICD-10-AM Seventh edition (I84). In ICD-10-AM Eighth edition haemorrhoids are classified with diseases of the digestive system (K64). Consequently, haemorrhoids are not included in the total count of diseases of circulatory system (i.e. cardiovascular diseases, I codes).

    • Key points: Circulatory disease

      • Circulatory diseases cause more than 15,000 deaths and 150,000 hospitalisations of NSW residents in each year. Coronary heart disease and atrial fibrillation and flutter contribute the most to these diseases' hospitalisation burden, followed by heart failure and strokes.

      • Death rates, and numbers of deaths, from circulatory disease are consistently higher in males than in females. Death rates are higher in Inner regional, Outer regional and Remote areas of NSW than in Major cities.

      • Death rates from all forms of circulatory disease have more than halved in the last twenty years after adjusting for population ageing. This is due to both:

        • decreased incidence, associated with reductions in some risk factors, including smoking, saturated fats in the diet, and levels of blood pressure;

        • increased survival, as a result of improvements in medical and surgical treatment and follow-up care.

      • Coronary heart disease caused 5,928 deaths in 2017. Coronary heart disease was the principal reason for 46,602 hospitalisations in NSW in 2017-18.

      • Stroke caused just over 2,803 deaths in NSW in 2017. Stroke was the principal reason for 13,093 hospitalisations in NSW in 2017-18.

      • Heart failure was the underlying cause of 1,116 deaths in NSW in 2017 and was a contributing cause in many more. Heart failure was the principal reason for 17,543 hospitalisations in NSW in 2017-18.

      • In the treatment of coronary heart disease, the number of percutaneous transluminal angioplasty (PCTA) procedures (with and without stents) first exceeded the number of the more invasive coronary artery bypass graft (CABG) procedures in 2000-01. More than 15,000 PCTAs were performed in 2017-18, more than three times as many as CABGs at around 4,000 procedures.

    • Introduction: Circulatory disease


      Cardiovascular (or circulatory) diseases comprise all diseases of the heart and blood vessels. Among these diseases, the four types responsible for the most deaths in NSW are: coronary heart disease (or ischaemic heart disease), stroke (or cerebrovascular disease), heart failure, and peripheral vascular disease. Other causes of death are cardiac arrhythmias (most notably atrial fibrillation), heart valve disorders, non-ischaemic cardiomyopathies, pulmonary embolism, and hypertensive renal and heart disease. Significant causes of morbidity include hypertension, deep vein thrombosis, haemorrhoids and varicose veins.

      Burden of disease

      Cardiovascular diseases accounted for 14% of the total disease burden in Australia in 2015, second only to cancers. The burden from cardiovascular diseases was predominantly fatal (78.5%) with only 21.5% due to non-fatal burden. Coronary (ischaemic) heart disease ranked highest in total individual disease burden (6.9% of the total burden) and stroke ranked ninth highest (2.7% of the total disease burden). 

      Presently, cardiovascular diseases account for around 48,000 deaths in Australia (around 33-34% of all deaths), more than any other group of diseases. This proportion has been in decline since 1970, when nationally cardiovascular diseases were responsible for over half of all deaths.

      Risk factors

      The four major causes of death from cardiovascular disease share a number of behavioural risk factors (tobacco smoking, physical inactivity, poor diet, risky alcohol consumption) leading to physiological risk factors (high blood pressure, elevated blood lipids, diabetes mellitus, and overweight or obesity).

    • Interventions: Circulatory diseases and Preventive Health

      Circulatory diseases share many modifiable risk factors with other lifestyle-related chronic diseases such as type 2 diabetes. These include smoking, physical inactivity, poor diet, harmful alcohol consumption and being overweight. This means that strategies related to the prevention, early detection and optimal management of these risk factors will lead to better health outcomes for people with circulatory diseases and other lifestyle-related chronic diseases.
