Table 1.
Side-by-side comparison table of the 130/80 mmhg cutoff vs. 140/90 mmhg cutoff for defining hypertension
| 130/80 mmHg Cutoff | 140/90 mmHg Cutoff | |
|---|---|---|
| Primary Rationale | Aligns with evidence (e.g., SPRINT) showing benefits of earlier intervention and tighter BP control in high-risk groups | Historically based on epidemiologic and trial data linking ≥ 140/90 mmHg to increased risk; avoids overdiagnosis |
| Population Labeled Hypertensive | Significantly more (about 46% of U.S. adults) | Fewer (about 32% of U.S. adults) |
| Impact on Early Detection | Detects more patients with elevated cardiovascular risk earlier | May miss some at-risk individuals with BP 130–139/80–89 mmHg |
| Effect on Cardiovascular Outcomes | Potential for greater long-term risk reduction, especially in high-risk populations | Proven benefit in reducing CVD events at ≥ 140/90, but may delay intervention for moderate elevations |
| Treatment Threshold | Lifestyle changes recommended for all; medication typically reserved for high-risk patients or those with CVD, CKD, or diabetes | Lifestyle modification first; medication typically starts at ≥ 140/90 (or ≥ 130/80 in certain high-risk groups) |
| Risk of Overtreatment | Higher—more individuals may receive medication despite modest absolute risk | Lower—focuses treatment on those with more clearly elevated BP and higher risk |
| Side Effects & Safety Concerns | Greater potential for medication-related adverse effects (hypotension, falls, electrolyte disturbances) in low-risk individuals | Lower risk of overtreatment side effects |
| Healthcare System Burden | Increased—more frequent monitoring, counseling, and follow-up required | More limited patient load for monitoring and treatment |
| Patient Psychological Impact | More individuals labeled as hypertensive, possibly increasing anxiety or altering self-perception of health | Fewer individuals diagnosed; less anxiety but risk of delayed intervention |
| Global Guideline Alignment | Matches current U.S. AHA/ACC approach; differs from most European guidelines (still at 140/90) | Matches ESC and other regions’ recommendations |
