HFpEF Diagnostic Criteria

HFpEF is diagnosed when a patient has symptoms/signs of heart failure, LVEF ≥50%, elevated natriuretic peptides (BNP >35 pg/mL ambulatory or >100 pg/mL hospitalized; NT-proBNP >125 pg/mL ambulatory or >300 pg/mL hospitalized), AND evidence of increased LV filling pressures or structural cardiac abnormalities. 1, 2

Core Diagnostic Requirements

The diagnosis requires ALL of the following components:

1. Clinical Presentation

Look specifically for:

  • Dyspnea on exertion (most common, present in ~65% with overt congestion and ~35% with isolated exertional symptoms) 3
  • Orthopnea
  • Jugular venous distension
  • Rales on lung examination
  • S3 gallop rhythm
  • Peripheral edema
  • Hepatojugular reflux 2

2. LVEF Threshold

  • LVEF must be ≥50% on echocardiography 1

3. Elevated Natriuretic Peptides

Specific cutoffs differ by clinical setting 2:

  • Ambulatory patients: BNP >35 pg/mL OR NT-proBNP >125 pg/mL
  • Hospitalized patients: BNP >100 pg/mL OR NT-proBNP >300 pg/mL

Important caveat: Natriuretic peptide levels are typically LOWER in HFpEF compared to HFrEF for the same degree of elevated filling pressure, and obesity (prevalent in HFpEF) further suppresses these values 2

4. Evidence of Cardiac Dysfunction

Must demonstrate at least one of the following 1:

Echocardiographic evidence:

  • E/e' ratio ≥15 (most definitive single parameter) 1
  • E/e' ratio 9-14 with additional supportive findings 1
  • Left atrial volume index ≥34 mL/m² 4
  • Increased LV mass index
  • Pulmonary artery systolic pressure >35 mm Hg 1

OR invasive hemodynamic evidence:

  • Elevated pulmonary capillary wedge pressure
  • Elevated LV end-diastolic pressure at rest or with exercise 1

Diagnostic Algorithm

Step 1: Initial Assessment

When dyspnea/edema is present:

  1. Obtain natriuretic peptides
  2. Perform echocardiography to assess LVEF and diastolic parameters
  3. Calculate H2FPEF score if diagnosis uncertain 1, 3

Step 2: H2FPEF Score Application

This validated clinical tool integrates 1, 3:

  • H = Heavy (obesity, BMI >30): 2 points
  • H = Hypertension (≥2 antihypertensive medications): 1 point
  • F = Atrial Fibrillation (paroxysmal or persistent): 3 points
  • P = Pulmonary hypertension (PA systolic pressure >35 mm Hg): 1 point
  • E = Elder (age >60 years): 1 point
  • F = Filling pressure (E/e' >9): 1 point

Score interpretation:

  • Score >5: >95% probability of HFpEF 3
  • Score 0-1: Low probability, consider alternative diagnoses

Step 3: When Diagnosis Remains Uncertain

If resting evaluation is inconclusive (particularly in the ~35% presenting with isolated exertional dyspnea) 3:

Perform stress testing with:

  • Exercise echocardiography evaluating diastolic parameters during stress 1
  • OR invasive hemodynamic exercise testing measuring pulmonary capillary wedge pressure, PA pressures, stroke volume, and cardiac output 1

Critical Diagnostic Pitfalls

Must Exclude HF Mimics

Before confirming HFpEF, rule out 2:

  • Valvular disease (especially mitral stenosis, aortic stenosis)
  • Infiltrative cardiomyopathies (amyloidosis, sarcoidosis)
  • Pericardial disease (constrictive pericarditis, tamponade)
  • High-output states
  • Pulmonary disease as primary cause of dyspnea

Recognize Diagnostic Challenges

  • Obesity blunts natriuretic peptide levels - don't rely solely on these values in obese patients 2
  • Atrial fibrillation elevates natriuretic peptides independent of filling pressures
  • Elderly patients may have multiple comorbidities contributing to dyspnea 5
  • Asian populations present younger with higher diabetes/CKD prevalence 6

Simplified Practical Approach

For patients with unexplained dyspnea and LVEF ≥50%:

  1. If E/e' ≥15: Diagnosis confirmed 1

  2. If E/e' 12-14: Diagnosis likely, check for supporting evidence (elevated natriuretic peptides, increased LA volume, elevated PA pressure) 4

  3. If E/e' 8-11: Requires additional criteria - need EITHER left atrial volume index ≥34 mL/m² OR Ard-Ad >30 ms (difference between reversed pulmonary vein atrial flow and mitral A wave duration) 4

  4. If E/e' <8: Consider stress testing or alternative diagnoses 1

This structured approach provides 77% sensitivity and 81% specificity for identifying diastolic dysfunction in HFpEF 4.
