Utilize guidelines, but customize BP treatment in older patients

Authors’ response:

We agree with the title of this letter, “Utilize guidelines, but customize BP treatment in older patients.” Our recommendations are not limited to targeting a systolic BP <120 mm Hg for community-dwelling, nondiabetic adults ≥75 years of age, but include consideration for “undue burden.” Our third practice recommendation, which recommends that one consider cognitive function, polypharmacy, multimorbidity, and frailty, is an equally—if not more—important recommendation.

With regard to the specific concerns about the current guidelines:

1. The American College of Physicians and American Academy of Family Physicians’ “Recommendation 1” advocates a systolic BP goal <150 mm Hg for adults ≥60 years of age. However, “Recommendation 3” endorses intensifying treatment in adults ≥60 years of age at high cardiovascular (CV) risk. Based on Framingham criteria, all adults ≥75 years of age are considered at high risk for CV disease, as stated in our article. Therefore, “Recommendation 3” for a target of <140 mm Hg is applicable for the population addressed in our article.¹
2. The Eighth Joint National Committee (JNC 8) does recommend a BP target <150 mm Hg for adults ≥60 years of age, but does not take into account recent data, which is why we wanted to highlight that data for physicians.²
3. Since submission of our article, The American College of Cardiology/American Heart Association (ACC/AHA) has published its first set of guidelines since 2003, which lowered BP target to <130 mm Hg in patients with high CV risk. Those guidelines outline the validity of SPRINT and the consistency of the existing evidence, including the linear relationship of BP and mortality.³
4. SPRINT was halted early specifically because of the mortality benefit in the intensive treatment group, which is ethically appropriate.⁴ It is unclear to us how this compromises the validity of the trial. There is often concern for bias from early cessation in small trials, but this was a large, well-powered trial.
5. The ACC/AHA guidelines also address some of the nuances of ACCORD, which is specific to patients with diabetes (whom we excluded from our first Practice Recommendation). Although no overall mortality benefit was found, there was stroke reduction in this group and additional benefit in the standard glycemia group.^3,5 A meta-analysis of SPRINT and ACCORD showed CV disease reduction with a BP target <120 mm Hg.⁶

Although we do believe that SPRINT is a landmark trial, we strongly emphasized that comorbidities, frailty, and dementia greatly impact treatment decisions.

Although we do believe that SPRINT is a landmark trial contributing a great deal to our recommendations, we strongly emphasized that comorbidities, frailty, and dementia greatly impact treatment decisions. We stressed that prescribers use caution and slow titration because of adverse effects. Geriatric medicine is a complex art, and one of the goals of our article was to highlight this complexity and emphasize the importance of considering goals of care, comorbidity, frailty, and cognitive function when choosing optimal BP targets.
