LONDON ESC— Simplified and more aggressive targets are among the significant changes to the updated hypertension guidelines released by the European Society of Cardiology ESC.

For most treated patients, the new systolic blood pressure goal is a target of 120 mm Hg to 129 mm Hg, which is a move away from the previous two-step recommendation.

Although the updated guidelines, presented here at the ESC Congress, continue to define hypertension as a systolic BP of at least 140 mm Hg and a diastolic BP of at least 90 mm Hg, there is a new category — elevated BP. This is defined as a systolic BP of 120 mm Hg to 139 mm Hg or a diastolic BP of 70 mm Hg to 89 mm Hg and cardiovascular risk assessment is advised to guide treatment, particularly in patients with a BP of at least 130/80 mm Hg.

The guidelines also introduce new recommendations for lifestyle options to help lower BP, including changes to exercise advice and the addition of potassium supplementation. And for the first time, the ESC guidelines provide recommendations for the use of renal denervation to treat hypertension in certain circumstances.

The guidelines were produced by an international panel, led by Bill McEvoy, MB BCh, from the University of Galway, Ireland, and Rhian Touyz, MB BCh, PhD, from McGill University in Montreal.

Three Categories of Blood Pressure

There are now 3 categories for BP classification — non-elevated (<120/70 mm Hg), elevated (120 mm Hg to139 mm Hg/70 mm Hg to 89 mm Hg), and hypertension (≥140/90 mm Hg) — McEvoy reported during a session on the new guidelines here at ESC.

The emphasis on out-of-office BP measurement is stronger than in previous guidelines, but office measurement will still be used, he said.

All patients in the hypertension category qualify for treatment, whereas those in the new elevated BP category will be subject to cardiovascular risk stratification before a treatment decision is made.

Patients in the elevated BP category who also have moderate or severe chronic kidney disease, established cardiovascular disease, diabetes, or familial hypercholesterolemiaare among those considered at increased risk for cardiovascular disease, as are patients with an estimated 10-year cardiovascular risk of 10% or higher. In such patients with a confirmed BP of at least 130/80 mm Hg, after 3 months of lifestyle intervention, pharmacologic treatment is recommended.

”This new category of elevated blood pressure recognizes that people do not go from normal blood pressure to hypertensive overnight,” McEvoy said. ”It is, in most cases, a steady gradient of change, and different subgroups of patients — for example, those at a higher risk of developing cardiovascular disease — could benefit from more intensive treatment before their blood pressure reaches the traditional threshold of hypertension.”

New Lower Target

The major change in target pressures in these guidelines is based on new clinical trial data that confirm that lower pressures lead to lower cardiovascular event rates, resulting in the new systolic BP target of 120 mm Hg to 129 mm Hg for most patients receiving antihypertensive medications.

This systolic target represents a major change from previous European guidelines, McEvoy said, which have generally recommended that patients be treated to a target of less than 140/90 mm Hg and, only after that has been reached, then treated to a target of less than 130/80 mm Hg (a two-step approach).

”This change is driven by new trial evidence confirming that more intensive blood pressure treatment targets reduce cardiovascular outcomes across a broad spectrum of eligible patients,” McEvoy said.

There are, however, several caveats to this recommendation, including the requirement that treatment to this target be well tolerated; more lenient targets can be considered in people with symptomatic orthostatic hypotension, those 85 years and older, and those with moderate to severe frailty or a limited life expectancy. For these patients, the guidelines recommend a target ”that is as low as reasonably achievable.”

More in Line With US Guidelines

The new European guidelines are now more in line with the American guidelines, said Eugene Yang, MD, from the University of Washington in Seattle, who is chair of the Hypertension Writing Group at the American College of Cardiology.

”These new European guidelines have thoughtfully used the latest study data to simplify recommendations for a specific lower blood pressure target. This is a step forward. There is now a greater alignment of European and US guidelines. This is good to reduce confusion and build consensus across the world,” he said.

Both sets of guidelines now recommend a BP target of less than 130/80 mm Hg for most people. 

”I think the Europeans have now embraced this more aggressive target because there are many more studies now showing that these lower blood pressure levels do lead to a reduction in cardiovascular events,” Yang explained. ”When the last European guidelines came out, there was only SPRINT. Now there are several more studies showing similar results.”

New Lifestyle Advice

The updated recommendation of 75 minutes of vigorous-intensity aerobic exercise per week has been added as an alternative to the previous recommendation of at least 2.5 hours per week of moderate-intensity aerobic exercise. This should be complemented with low- or moderate-intensity dynamic or isometric resistance training two to three times a week. 

It is also recommended that people with hypertension, but without moderate or advanced chronic kidney disease, increase potassium intake with salt substitutes or diets rich in fruits and vegetables.

Renal Denervation Included for First Time 

For the first time, the guidelines include the option of renal denervation for the treatment of hypertension — at medium- to high-volume centers — for patients with resistant hypertensionthat is uncontrolled despite a three-drug combination.

However, renal denervation is not recommended as a first-line treatment because of the lack of evidence of a benefit in cardiovascular outcomes. It is also not recommended for patients with highly impaired renal function or secondary causes of hypertension.

Yang said he approves of the inclusion of a frailty assessment in the new guidelines and less aggressive targets for people who are in poor health and older than age 85 years, but added that, ”on the whole, they have less age-specific stratification than before, which is a significant change, and a good one in my view.” 

Again, this is like the American guidelines, which have no age cutoffs and a target of less than 130/80 mm Hg for all, with the caveat that clinical judgment may be needed for individuals who are institutionalized, he added.

Yang said he was not as keen on the requirement for a cardiovascular risk assessment to guide treatment decisions for people with a systolic BP in the 130 mm Hg to 139 mm Hg range, although this is also included in the current American guidelines.

”As a clinician, I think this complicates things a bit too much and, as such, will be a barrier to treatment. In my view, blood pressure treatment recommendations need to be as simple as possible, so I think we still have some work to do there,” he said.
