Abstract 3671: Blood Pressure is Inadequately Treated in Australia Especially Among Males and Those Under Sixty Five Years
OBJECTIVE: To assess the adequacy of blood pressure (BP) treatment among the contemporary adult Australian population with high cardiovascular risk.
METHODS: Data were analyzed from over 53,355 Australians aged 18 years and above enrolled in a large, community-based study of subjects with high cardiovascular risk. Eligibility criteria for BP treatment and target BP levels were derived from the Australian National Heart Foundation, as recommended by JNC VII.
RESULTS: Within the sample, 39,854 subjects met eligibility criteria for BP lowering treatment according to guidelines. Of these, 12,159 (30.5%) were not receiving therapy. The proportion of subjects not receiving therapy when indicated was greater among males than females (32.7% vs 28.1%, p<0.001), and among subjects aged less than 65 years than those greater than 65 years (36.4% vs 22.4%, p<0.001). Of the 34,996 treated subjects, 19,345 (55.28%) had blood pressures above recommended target levels. Again, males (57.1% vs 53.6%, p<0.001) and subjects aged less than 65 years (60.6% vs 48.5%, p<0.001) were more likely to be inadequately treated.
DISCUSSION: Currently in Australia, there is considerable deficiency in the treatment of BP among individuals with high cardiovascular risk, both in terms of initiation of therapy and achievement of target BP levels. Patients who are inadequately managed are more likely to be male and aged less than 65 years. That this represents a subgroup from which a large proportion of cardiovascular disease will arise highlights the potential for further prevention and the importance of closing this treatment gap.
