6 key facts on the rise of cardiac implants

Their use has more than tripled in a decade

The use of implantable cardioverter-defibrillators (ICDs) in Australia has more than tripled in the past decade.

But women may still be missing out, a study shows. 

More than three-quarters of the procedures are in men and this possible “underuse” of the devices in women needs further investigation, the researchers write in the Medical Journal of Australia.

Their study using Australian hospital data shows the number of ICD procedures increased from 1844 in 2002 to more than 6500 in 2014/2015, and now cost $155 million a year.

"Further investigations are needed to determine whether increasing rates of ICD therapy reflect evidence-based management decisions," the authors write.
