Paul,
re the ABPMs - ditch them. A very large systematic review has shown:-
1. They do not record BP accurately. Minor (unannounced )software
changes between various models of the same make & time occur & make a
difference.
2. The degree of inaccuracy is variable even within one patient
3. There is no consistent relationship between 24h mean, nocturnal mean
or daytime mean BP & end organ damage.
4. There are no agreed treatment levels - certainly using the same
levels of BP for treatment on ABPM as office readings appears to miss
people who are at significant risk.
One of our Masters students did a super 20K word review - interestingly
2 smaller published reviews over the last year or two came up with
similar results. Copy of the 20K version available!
