Outlineofthepresentation • Short reviewofepidemiologicalresearch • Underlying mechanisms for disability • Preventionofdisability • Take-homemessages
PrevalenceofHeartFailure (HF) • 80 % of HF patients are 65 years or older • 25 % of HF patients are 80 years or older AHA HeartDisease and Stroke statistics 2006 • Wong C. Am J Med 2011 ;124 :136-43. • .
Prevalenceofdisability in HF • 54% with ≥ 1 basic ADL disability • Mobility disability (42%) most common limitation • 57 % withmobilitydisability • 11 % anyother ADL limitation • Proportionwithdisability stable over 20 years Gure TR. J Gen Intern Med 2007.:23(1):70-76. • Wong C. Am J Med 2011 ;124 :136-43. • . • .

Major predictors for disability in HF • Impairedgait speed • Depressive symptoms • Cognitiveimpairment Chaudry S. J Card Fail2011;17(9) :764-70..
Mechanisms for disability in HF • Mobilitydisability • Muscleweakness Loncar G. Int J Cardiol2013;162(2) :77-85. • Reducedlungcapacity • Reducedperipheroxygenconsumption • Anemia • Fatigue
Mechanisms for disability in HF • Cognitiveimpairment • Lowcardiac output • Hypotension • Impaired cerebral vesselreactivity • Microembolism Dardiotis E. Cardiol Res Pract 2012;2012:595821 (Epub).
Preventionofdisability in HF • Optimal heartfailuretreatment • Angiotensin-convertingenzyme inhibitors Zuccalà G. EurHeart J 2005;26(3):226-233. Pedone C. J Gerontol A BiolSci Med 2004;59(7):716-721 • Treatmentof co-morbid conditions • Treatmentofdepression Vaccarino V. J Am Coll Cardiol 2001;38:199-205.
Preventionofdisability in HF • Regular physical exercise - prevents age-related decline in cardiac function Molmen HE. Scand Cardiovasc Journ 2012;46(3):163-71 - increases muscle strength in HF patients Savage P. Med Sci Sports Exerc 2011;43(8):1379-1386. - is safe in patiets with heartdisease RognmoØ.
