HFPEF: definition ESC 2005 A diagnosis of primary diastolic heart failure requires three obligatory conditions to be simultaneously satisfied: (1) presence of signs or symptoms of congestive heart failure; (2) presence of normal or only mildly abnormal left ventricular systolic function; (3) evidence of abnormal left ventricular relaxation, filling, diastolic distensibility or diastolic stiffness ESC 2012 ACC/AHA 2013 HF definition HFPEF definition Abnormality of cardiac structure or function leading to failure of the heart to deliver oxygen at a rate commensurate with the requirement of the metabolizing tissues, despite normal filling pressure (or only at the expense of increased filling pressures) Requires 4 conditions to be satisfied Typical symptoms of HF Typical signs of HF Preserved ejection fraction (EF 45%) and left ventricle not dilated Relevant structural heart disease and/or diastolic dysfunction Complex clinical syndrome that results from any structural or functional impairment of ventricular filling or ejection of blood Stage C heart failure Known structural heart disease Typical signs and symptoms Preserved ejection fraction (EF 50% HF-PEF, EF 41% 50% borderline HF-PEF)

HFPEF: causes 1. Cardiovascular risk factors: Arterial hypertension, Diabetes mellitus, Obesity, Atrial fibrillation, CAD, ageing 2. Non-cardiovascular risk factors: Renal impairment, chronic lung diseases, anemia, cancer, liver disease, peptic ulcer disease, hypothyroidism 2. Hypertophic cardiomyopathy 3. Valvular diseases 4. High-output HF (anemia, hyperthyroidism, liver disease, AV fistula) 5. Infiltrative disorders (e.g. amyloidosis, sarcoidosis) 6. Myocardial storages diseases (e.g. haemochromatosis) 7.

GLS is a strong independent predictor of all-cause mortality in patients with AOS pef GLS detects subclinical dysfunction and has incremental prognostic value over traditional risk markers including haemodynamic severity, symptom class, and LVEF in patients with AS. Independent predictor of all-cause mortality (HR: 1.38, P=0.001) Incorporation of GLS into risk models may improve the identification of the optimal timing for AV replacement.
