How would Aussies fare under American BP cut-offs?

Millions would be affected - but cardiologists say no change in BP targets is needed yet

Twice as many Australians would be classified as hypertensive if guidelines similar to US blood pressure cut-offs were adopted here, the MJA has reported.

Dropping treatment targets from 140/90mmHg down to 130/80mmHg, as is now the case in America, would change the health status of 4.5 million Australians, say the authors.
