In short, while the findings are interesting and may suggest more research is called for I would not stop taking my blood pressure medicine.  We already know that there are many other reasons for not letting blood pressure get too low - death notwithstanding.  Also keep in mind that blood pressure changes often during the day.  One lower reading should not be cause for alarm.

My readers know I do not hold the traditional medical establish in any great awe but, in this case, my advice is to discuss your blood pressure with your doctor if you think it may be too low.  There are plenty of other reasons to make needed adjustments to blood pressure beyond the interesting, yet unproven, causal connection between lower blood pressure and increased mortality.

Looking out for your heart health,
