Predicting Life Expectancy in Heart Failure Thierry H.Le Jemtel, M.D. Tulane University School of Medicine Impact of Heart Failure on the Health Care System • 20% of the elderly will develop some form of heart failure. • 1 - 2% of the total health care budget • More hospitalizations for heart failure than for cancer and myocardial infarction combined NEJM: 2002;Vol 347:1442-1444 Heart Failure with reduced ejection fraction i.e. Systolic Heart Failure. Heart Failure with preserved ejection fraction i.e. Diastolic Heart Failure Heart Failure Paradigm Shift Reduced LV Eject. Fraction 80 Women = 1/3 Men Preserved LV Eject. Fraction Women = 3/1 Men WOMEN Systolic Heart Failure (CAD) 70 MEN Prevalence (%) 60 Non-Systolic Heart Failure (HTN) 50 Systolic Heart Failure (CAD) 40 WOMEN 30 MEN Non-Systolic Heart Failure (HTN) 20 50 60 70 80 Age (years) Clinical Population in SOLVD, VHeFT, CONSENSUS 90 Vasculopathy • Hypertension • Diabetes • CAD Chronic Kidney Disease 30-40% Obesity Congestive Heart Failure PPCM IDCM Circulation 1993: 88:107-115 NEJM: 2000; 342:1077-1084 • Physician’s standpoint: < 1 year- Cardiac transplantation Mechanical Circulatory Support < 6 months- Referral to Hospice > 2 years- Implantable cardioverter defibrillators when ejection fraction is less than 35% JAMA 2008; 299 :2566 PATIENT’S STANDPOINT ?
