The Hidden Epidemic of Hypertension

The majority of cardiovascular disease (CVD) is caused by risk factors that can be controlled, treated or modified. In terms of attributable deaths, the leading cardiovascular disease risk factor is hypertension.The Australian Health Survey results showed some startling figures-4.6 million adult Australians are hypertensive (>140/90. mmHg). Further, a fifth of the adult population experience hypertension, with more than two out of three not attaining blood pressure target levels. This is despite an estimated cost of $1 billion per annum spent on managing hypertension.It is now well recognised that the level of risk for coronary heart disease is linked to an individual's risk profile. Results indicate that many Australians have multiple risk factors, including hypertension. It could be considered that these numbers provide a proxy indicator of secondary prevention failure.Considerable attention needs to be given to the assessment of the combined risk of those with hypertension enabling effective management of identified, modifiable risk factors. We look forward to presenting the absolute risk profiles when the Australian Health Survey biometric results are released.
