Six days ago the National Institutes of Health announced the results of a new landmark study showing that lives were saved with 25% fewer deaths when more aggressive therapy was used to achieve a target systolic blood pressure of 120, as compared with the previous target recommendation of 140 (

Even more dramatic was the reduction in cardiovascular events where the study showed that heart attacks, heart failure, and stroke were reduced by almost a third.  The results were so dramatic that the study was stopped prematurely. Nevertheless, concerned physicians have noted that the NIH first issued a press release to the public containing only sparse details of the “SPRINT” study instead of following their usual protocol of first releasing more detailed results to the scientific community where the results could be analyzed and critiqued. For example, Dr. Lloyd Van Winkle, who is a candidate for the presidency of the American Academy of Family Physicians, on his 9/14/2015 Facebook page wrote “Hmm… But at those goals how many hip FX from orthostatic hypotension on standing?” Data to answer Dr. Van Winkle’s concern is sure to be found in the study results but it cannot presently be accessed by physicians. And with most experienced physicians having seen multiple instances of having preliminary findings subsequently reversed, the NIH announcement is quite naturally viewed by many physicians with some skepticism. But perhaps this study will be an impetus to have more patients monitor their blood pressure at home, especially since smartphone apps in combination with the associated blood pressure cuff allow ease of taking and keeping historical blood pressure records. If the first number on your blood pressure reading (i.e., systolic blood pressure) is consistently above 120, you should consider a visit to your doctor to determine whether you are a candidate for treatment.
