In her presentation at the 2015 AHA Fall Conference, Nanette K. Wenger, MD, spoke about management of high blood pressure in the elderly. Wenger showed case studies to illustrate variations of blood pressure among elderly patients and how to manage them.
Management of high blood pressure in the elderly requires individualizing treatment based on a combination of clinical practice guidelines, patient preferences, and ultimately clinician judgment, according to Nanette K. Wenger, MD, professor of medicine (cardiology) emeritus at Emory University School of Medicine in Atlanta.
“There really is no template for the oldest old,” she said.
During her presentation entitled “HTN Management in the Older Old: Is It Ever Too Late?” at the American Heart Association (AHA) meeting, Wenger used case studies to illustrate the variations among the elderly from the frail to the functional and “all the variables in the middle.”
She opened her talk discussing two patients, both white, 87-year-old men with blood pressure at 180/100 mmHg. One man was active and alert and played golf twice weekly, had diabetes controlled with metformin, and hypercholesterolemia controlled with a statin. The other man with the same elevated blood pressure had mild cognitive impairment and needed a walker, severe osteoarthritis, atrial fibrillation with no anticoagulation because of a fall risk, and prostate cancer not currently being treated.
Given the variability among the elderly, Wenger emphasized the need to combine clinical guidelines with patient preferences and then use clinical judgment to manage each patient according to their needs.
Table 1 lists a number of clinical practice guidelines she described.
|Science Advisory AHA/ACC/CDC (||BP goal <140/<90/mm/Hg for most people|
|2014 Evidenced-Based Guideline for the Management of High Blood Pressure in Adults (JAMA 2014;311:507)||Strong evidence to treat hypertensives aged 60 or older to BP goal <150/90 mm/Hg (JNC8)|
|ACCF/AHA Expert Consensus Documentation on Hypertension in the Elderly (for Patients >Age 80) (J Am Coll Cardiol 2011;57:2037)||Lifestyle changes beneficial|
Further guidance may be forthcoming from the Systolic Blood Pressure Intervention Trial (SPRINT), which is assessing the outcomes between reducing systolic BP <140 mmHG versus <120 mmHg and includes a subset analysis of the elderly.
Overall, Wenger stressed the need to include lifestyle modifications when managing hypertension in older old adults, as well as starting on low dose of pharmaceuticals and titrating slowly, while also considering the presence of comorbidities.

The issue of target blood pressure for elderly patients with hypertension is an important public health issue. In determining a target blood pressure for a particular older individual, physicians should consider the following:
In SPRINT, among patients at high risk for cardiovascular events but without diabetes, a target systolic blood pressure of <120 mm Hg (rather than 140 mm Hg) was associated with a 35% lower cardiovascular event rate and 25% lower all-cause mortality. SPRINT investigators have reported higher rates of hypotension, syncope, electrolyte abnormalities, and acute kidney injury among those in the intensive-treatment group. SPRINT is continuing with respect to renal and CNS outcomes.
