Hypertension and the J-curve phenomenon: implications for tight blood pressure control

The term J-curve is used in several fields of science to refer to a variety of J-shaped diagrams where a curve initially falls, but then rises to higher levels. In cardiovascular (CV) medicine, the J-curve phenomenon arises when a risk factor becomes inversely related to risk below a certain point, whereas the more widely accepted positive risk association exists across most of the observed risk factor distribution. In simpler terms, when elevated blood pressure (BP) is lowered, the risk of CV events decreases, but lowering BP below a critical ‘nadir’ is no longer beneficial and possibly deleterious, thus shaping a J-curve.
