My patient has a lot of variability in his blood pressure measurements? Should I be worried? What can I do which may be better?

Hypertension is a strong risk factor for stroke. In literature most work on hypertension has been done targeting either the Systolic blood pressure, Mean blood pressure or Pulse pressure but the ideal value which best measures the effect of anti-hypertensive drugs and predicts outcome in terms of complications and mortality has not been identified yet. Two international trials, ASCOT-BPLA and MRC, have been analyzed by investigators who have defined that blood pressure variability when measured is able to predict the outcome and have shown that "beta blockers" are showing a negative effect on stroke risk by affecting blood pressure variability and that Calcium channel blockers may in fact be better as they have shown to decrease the stroke risk in this sub analysis by decreasing intrapatient variability.
