4 HFPEF Is it really Heart Failure? 1. How to diagnose HFPEF current standards 2. CV abnormalities beyond diastole 3. Role of comorbidities

5 How to diagnose HFPEF? Standard approaches: a) HFPEF = Heart Failure + EF 40/45/50% ( Mega-Trial- Approach ) b) HFA/ESC-Criteria 2007 c) EAE/ASE-Criteria 2009 d) New ESC HF Guidelines 2012

6 I-Preserve Echo Substudy

7 I-Preserve Echo Substudie I-Preserve included 4128 patients with HFPEF Inclusion criteria: Age 60 years, EF 45%, recent Heart Failure hospitalisation or moderate/severe symptoms + 1 sign (pulmonary congestion; LBBB; Echo: increased wall thickness; LA enlargement Echo-Substudy: 745 patients with 2D, Doppler- and tissue doppler analyses at randomisation

8 Structural LV Remodeling Almost 50%: no structural LV Remodeling! Zile et al.; Circulation 2011; 124

9 LA-Remodeling & Diastol. function 1/3: No LA-Remodeling! 1/3: normal diastolic function! Zile et al.; Circulation 2011; 124

10 Remodeling and Prognosis I-Preserve Echo Substudy: Objective evidence of remodeling/diastolic dysfunction = more heart failure endpoints! LV Hypertrophy LA Dilatation Diastolic Dysfunction Zile M et al.; Circulation 2011; 124:

11 HFA/ESC Recommendations Paulus W et al., Eur Heart J 2007;

12 HFA/ESC Recommendations: Diagnosis 1. Signs and/or Symptoms of Heart Failure 2. Preserved global systolic LV Function (EF>50%) 3. Indices of abnormal LV relaxation, filling, compliance or stiffness 4. BNP or NTproBNP

13 Diagnosis: Diastolic Heart Failure HFA/ESC 2007 Paulus W et al.

14 Diagnosis: Diastolic Heart Failure HFA/ESC 2007 Paulus W et al.

15 E/é and LVEDP Little et al.; Circulation 2009; 120:

16 Diagnosis: Diastolic Heart Failure HFA/ESC 2007 Paulus W et al.

17 NTproBNP in I-Preserve Baseline plasma NT-proBNP and clinical characteristics: results from the irbesartan in heart failure with preserved ejection fraction trial. McKelvie RS, Komajda M, McMurray J, Zile M, Ptaszynska A, Donovan M, Carson P, Massie BM; I-Preserve Investigators. Majority in NYHA III Median NTproBNP: 341 ( ) pg/ml No Atrial fibrillation: around 250 pg/ml (ca. 75%) With atrial fibrillation: >900 pg/ml (ca. 25%)

22 Diagnosis: HFPEF Change in Paradigms 2012: New Echo Techniques & Parameters Stress tests ( Diastolic Stress Test )! New Biomarkers: Subgroups, Response to Therapy

23 New Echo Techniques Strain rate imaging & Diastolic stress test Left atrial strain Rotation, Twist & Untwist Oh JK et al., Circulation Cardiovasc Imaging 2011;

26 Diagnostic accuracy of exercise PASP Borlaug et al.; Circ Heart Fail 2010; 3:

27 HFPEF - Diagnosis There are no generally accepted diagnostic criteria Large Mega-Trials may have included patients without cardiac origin of symptoms The diastolic stress test and novel imaging parameters may improve diagnostic accuracy

28 HFPEF Is it really Heart Failure? 1. How to diagnose HFPEF current standards 2. CV abnormalities beyond diastole 3. Role of comorbidities

29 Ventricular Dysfunction Impaired relaxation Impaired filling Systolic Dysfunction Atrial dysfunction Autonomic dysfunction Chronotropic incompetence Vascular dysfunction Vascular stiffening Ventriculo-arterial coupling Heart failure with preserved EF Elevated blood pressure Inadequate BP response to exercise Pulmonary hypertension Valvular disease Dynamic mitral regurgitation

31 LA contractile dysfunction No increase in LA contractile function (assessed by tissue doppler mitral annular A wave velocity) in HFprEF during stress Melenovsky et al., J Am Coll Cardiol 2007; 49(2)

32 Chronotropic incompetence HFprEF (n=17) and matched controls (n=19): maximal effort upright cycle ergometry & radionuclide-ventriculography Matched workloads: Reduced chronotropic, vasodilator, and cardiac output reserve during exercise Borlaug et al., Circulation 2006; 114(20) Kitzman et al., Circulation 2008; 117

43 Summary HFPEF is a heterogeneous syndrome Patients need to be classified according to the underlying pathophysiology and CV phenotypes Co-morbidities have to be taken into account Specific etiologies need to be excluded In clinical practice, we often deal with a mixed picture of cardiac and extracardiac abnormalities that sum up to HFPEF
