New Hypertension Guidelines: Why Neurologists Should Pay Attention

Scientific Sessions generated a great deal of buzz in the traditional and social media spheres, particularly with regards to the new ACC/AHA High Blood Pressure Guidelines. The lay media was quick to note that nearly half of the US population will now be considered hypertensive, and some doctors expressed concern that some patients may incur undue harm from over-zealous anti-hypertensive therapy.
 
It is important first to note that the guidelines do not require or recommend that individuals with blood pressure values falling in the “Elevated Blood Pressure” or “Stage I Hypertension” categories be reflexively treated with anti-hypertensive medication. There is room for consideration of overall-risk and prior cardiovascular events. There is an explicit role for non-pharmacological therapy. Some have noted that that while the number of individuals now considered “hypertensive” will increase, the number requiring pharmacological treatment will not increase as dramatically.
 
That said, why should neurologists pay attention? First, the previously-used term “pre-hypertensive” is decidedly not alarming. The updated guidelines’ use of “elevated blood pressure” is clear and unambiguous; patients and their physicians will be prompted to action earlier. Given that hypertension is a leading risk factor for stroke, we will hopefully see stroke rates decrease with time. Second, neurologists should pay attention because some patients may see us more frequently than their primary care physicians. We should be aware of these guidelines so that we are prepared to appropriately counsel and/or refer patients with elevated blood pressure. A check-in for a migraine or epilepsy medication refill may yield an opportunity to reduce long-term cardiovascular risk!
 
I look forward to seeing the public health gains materialize from dissemination and implementation of these guidelines.

New Hypertension Guidelines: Should They Inform The Way We Care For Pediatric Cardiology Patients?

In reflecting on my time at the 2017 AHA Scientific Sessions, I can summarize my thought process about the new AHA Hypertension Guidelines as a complete 180.  When I first heard about the guidelines, my inner monologue went something like this:

“I don’t need to pay attention to these guidelines – they don’t affect me or my patients.  We already have separate pediatric guidelines.  Wasn’t there a new set of guidelines this year?  Maybe I should look at them a little closer…”

After reviewing the 2017 pediatric hypertension guidelines, I was pleasantly surprised how well they align with the AHA adult guidelines.  Of course, the pediatric guidelines are a little more complicated, since all of our patients have different cutoffs based on age, gender, and height.  And the cutoffs are now lower, due to the exclusion of overweight/obese children in the normative data.  But once our patients become adolescents, the cutoffs are the same as the new AHA adult guidelines.
After hearing that now nearly half of all U.S. adults will meet the diagnostic criteria for hypertension under the new guidelines, I realized: “OMG! Almost all of my patients are going to turn 13 and be hypertensive!”

Of course, as pediatric cardiologists, our patients are at especially high risk of cardiac events in adulthood, and the adult congenital heart disease population continues to grow every day, so we should be even more aware of hypertension as a significant risk factor for these children.  As Bradley Marino, MD (Chair of the Council on Cardiovascular Disease in the Young) stated during the CVDY Council Dinner, in light of current changes in the hypertension guidelines and national trends in increasing rates of obesity and heart disease-related morbidity, our role as pediatricians and cardiologists in prevention is becoming more and more important.

By the end of Scientific Sessions and in the weeks thereafter, I have become more cognizant and appreciative of my role in preventing my own patients from becoming hypertensive.  Of course, my ability to encourage lifestyle changes and long-term nutritional improvements is quite limited in the CVICU, but I am much more appreciative of my colleagues in the outpatient world and those who specialize in preventative pediatric cardiology.  I have also made a few lifestyle changes myself, since I am now uncomfortably close to meeting hypertension criteria.
