Clinical Scorecard: PAHR: Prognostic Marker in Severe Aortic Stenosis?
At a Glance
| Category | Detail |
|---|---|
| Condition | Severe Aortic Stenosis |
| Key Mechanisms | Pressure-adjusted heart rate (PAHR) integrates chronotropic response, venous congestion, and systemic pressure. |
| Target Population | Adult patients with severe native aortic stenosis identified on transthoracic echocardiography. |
| Care Setting | Cardiovascular medicine and echocardiography. |
Key Highlights
- Higher PAHR values are associated with poorer survival in severe aortic stenosis.
- PAHR may identify higher-risk patients under medical management and post-aortic valve replacement.
- The study included 14,409 patients with severe aortic stenosis.
- Patients in higher PAHR quartiles had significantly increased risks of mortality.
- PAHR may provide complementary insight into patient risk before and after valve replacement.
Guideline-Based Recommendations
Diagnosis
- Severe AS defined by an aortic valve area of 1 cm² or less or an indexed aortic valve area of 0.6 cm²/m² or less.
Management
- Consider PAHR for risk stratification in patients with severe aortic stenosis.
Monitoring & Follow-up
- PAHR may inform closer surveillance and earlier evaluation for intervention.
Risks
- Higher PAHR quartiles are associated with increased mortality risk.
Patient & Prescribing Data
Adult patients with severe native aortic stenosis.
PAHR should be viewed as complementary to existing approaches and requires further validation.
Clinical Best Practices
- Utilize PAHR as a noninvasive estimate of hemodynamic burden in severe AS.
- Incorporate PAHR assessment into routine echocardiography and vital sign evaluations.
