Episode 102: Blood pressure targets: Bullseye or Bulls–t

In episode 102, Mike and James, with laser precision, look at the evidence around blood pressure targets. We cover data in non-diabetics, diabetics, chronic kidney disease and the elderly. At the end they agree that the BP target we used 30 years ago (140/90) is still pretty good. To prove the point James gives Mike some sublingual nifedipine and Mike demonstrates the J-curve by falling on the floor and ‘pretending’ to be unable to get up (faker!).
