The problem with heart rate is that it is not absolute. Heart rate is affected by a whole lot of physiological, psychological, and environmental factors.
LT is highly trainable compared to VO2Max, which is trainable when you first start training, but any further advances after that are very hard to accomplish and is determined by genetic factors.
Then, there's aging. VO2Max declines with age. LT can be improved with age, but will always be a fraction of your declining VO2Max.
These physiological "markers" (VO2Max and Lactate Threshold) can be expressed as heart rate for training purposes, but these heart rates are just a snapshot of the instance you were tested.
