Why the study?
Recent blood pressure guidelines agree on several aspects but differ regarding nomenclature, pharmacotherapy for individuals at lower cardiovascular risk, and aiming for systolic blood pressure below 120 mmHg.
This commentary highlights that the 2025 AHA/ACC hypertension guidelines advocate for more aggressive blood pressure diagnosis thresholds and treatment targets compared to recent European society guidelines.
Clinicians must navigate differing US-European BP thresholds; leaves open the need for global guideline harmonization.
American Scientific Societies (AHA/ACC and others) updated in 2025 the Guideline on High Blood Pressure following 2024 ESC and 2023 ESH updates from Europe. Guidelines mostly agree on who should receive pharmacotherapy and on a common target of systolic blood pressure (SBP <130 mmHg) and diastolic blood pressure (DBP) <80 mmHg for most, as well as on individualizing BP targets according to patient characteristics. However, they differ in nomenclature, pharmacotherapy for people at lower cardiovascular risk and aiming at SBP <120 mmHg. Overall, 2025 AHA/ACC supports pharmacotherapy earlier and achieving lower BP targets than other recent guidelines: it recommends (high CVD risk) or finds reasonable (not high CVD risk, if not corrected by lifestyle) initiating pharmacotherapy for hypertension, defined as SBP ≥130 mm Hg or DBP ≥80 mmHg. The recommended (high CVD risk) or reasonable (not high CVD risk) target is SBP at least <130 mmHg, with encouragement to achieve SBP <120 mmHg, and DBP <80 mmHg. However, 2024 ESC and 2023 ESH use alternative terms (high normal or elevated BP) for BP values (i.e., ≥130-139 or ≥80-89 mmHg) that require pharmacotherapy only in high-risk groups. Additionally, 2023 ESH recommends avoiding actively aiming for SBP <120 mmHg or DBP < 70 mmHg. 2024 KDIGO avoids the term hypertension and suggests a target SBP <120 mmHg for people with CKD. It would be desirable that guidelines converge on such key issues as nomenclature and therapeutic targets.

Kanbay et al. (2026) conducted a review in Hypertension. 2025 AHA/ACC Hypertension Guidelines was evaluated. The 2025 AHA/ACC guidelines support initiating pharmacotherapy for blood pressure ≥130/80 mmHg and achieving lower blood pressure targets (SBP <120 mmHg) compared to recent European guidelines.
