Background:
Budyari Community Health Centre offers a comprehensive program for the local Aboriginal population with or at risk of chronic disease.
AIMS:
Compare the estimated cardiovascular event risk using the Fremantle Diabetes Study (FDS) 5 year Cardiovascular Disease (CVD) risk calculator with the actual development of cardiovascular events in this group of predominantly Aboriginal patients with type 2 diabetes and analyse the characteristics of patients.
METHODS:
39 patients with T2DM were included. The FDS CVD Risk Calculator V1.41 used to predict CVD risk at enrolment and at current review (20/9/16).
RESULTS:
31(79%) patients are Aboriginal and 26 females, 13 males. Mean age at enrolment was 57.3 years which is 62.9 currently. At enrolment mean FDS 5 years CVD predicted risk was 25.5% which is 39.1% at current review. 10 (25.6%) patients had at least one CVD event which is 0.1% more than the risk predicted by the FDS 5 year calculator after a mean follow up period of 5.6 years.
The group of patients who experienced CVD event did have a higher initial predicted 5 year FDS calculated risk of 33.5 % compared to 23% for those that did not experience an event during follow-up.
Comparing the group of patients that did have a CVD event to the group that did not, the patients with an event were younger (61 vs 63.5 years), more likely to be Aboriginal (100% vs 82.7%), female (80% vs 62.1%), higher prevalence of prior CVD (60% vs 27.6%), higher HbA1c (8.9% vs 8.8%), lower urine albumin-creatinine ratio (9.3 vs 22.7 mg/mmol/L) with lower HDL cholesterol (0.99 vs 1.2 mmol/L).
CONCLUSIONS:
In an urban based group of people with type 2 diabetes of predominantly Aboriginal background the FDS 5 year CVD risk calculator was an accurate predictor of actual cardiovascular events over a similar time period.
