2 Definition of HF-PEF The diagnosis of HF-PEF requires four conditions to be satisfied: 1. Symptoms typical of HF 2. Signs typical of HF a 3. Normal or only mildly reduced LVEF and LV not dilated 4. Relevant structural heart disease (LV hypertrophy/la enlargement) and/or diastolic dysfunction ESC Guidelines, Eur Heart Journal 2012 Paulus W, Eur Heart Journal 2007

4 Symptoms, signs, normal LVEF:HF-PEF? Non dilated LV Dilated LV AR - MR High-output Incorrect HF diagnosis Obesity Inaccurate LVEF measurement Increase IVS thickness AS Normal IVS thickness MS Right ventricular dysfunction TR HCM Infiltrative C Hypertensive C Pericardial disease Ischemia Restrictive CM PAH COPD Congenital disease

20 What is the Prevalence of SAS in stable HF-PEF?

21 SAS prevalence in HF-PEF 20 patients with HF-PEF: LVEF>50% and with E/A<1. NYHA II-III, Age :65±6, 85% History of Hypertension, SBP :136±10mmHg; 65%Male AHI definition >10h -1 SDB :55% (n=11) AHI: 19.5± % OSA 37% CSA. Chan et al, Chest 1997

22 SAS prevalence in HF-PEF 244 HF-PEF ESC Definition Right heart catheterism with (LVEDP>20mmHg) SDB: 69%; AHI >5/h : SDB: 48%: AHI>15/h SDB: 25%: AHI>30/h Bitter T, Eur J Heart F 2009 IAH< 5; 30,7% OSA; 39,8% CSA, 29,5%

23 SAS prevalence in HF-PEF 115 patients; 72% HF-REF and 38% HF-PEF = 42 patients, AHI 5/h 115 patients IC dont 38% avec IC-FEP CSA :18% 81% 80% OSA :62% HF-REF HF-PEF Herrscher T, J Cardiac Fail 2011; 17:420e425

24 FACE observatory The FACE study is a French prospective, multicentre, observational cohort that will provide, in routine practice, long-term data on 300 CHF patients eligible for ASV (PaceWave, AutoSet). 174 patients enrolled LVEF <50% 50% CSA+OSA CSA LVEF 50% Age, years 70 75* Men, % BMI, kg/m² HTA, % Diabetes, % AF, % LVEF <50% AHI, H *

25 How should we treat them?

26 Adaptative servoventilation in HF-PEF with Cheyne-Stokes Respiration 60 patients with CSR, AHI>15/h and HFPEF defined accordingly to the ESC. ASV treatment for all. 21 rejected, withdrawn, non compliant 39 patients followed ASV.

29 Summary HF-PEF is frequent and no treatment has been shown to reduce mortality/morbidity in HF- PEF. Adequate treatment of comorbidities is recommended. They are pathophysiological relationships between SDB and HF-PEF.

30 Conclusion The Increase in the prevalence of HF-PEF over time AND the Stability in the rates of death underscore the importance of determining new concepts and new therapeutic strategies. SDB diagnosis and treatment should be one of these new concepts and strategies in HF-PEF.
