1. Heart Failure: ACC Guidelines for Dx and Management Steven W. Harris MHS PAC

2. Epidemiology Approximately 5 million patients in this country have HF Over 550,000 patients are diagnosed with HF for the first time each year Primary reason for 12 to 15 million office visits and 6.5 million hospital days each year In 2001, nearly 53,000 patients died of HF as a primary cause

3. Epidemiology The incidence of HF approaches 10 per 1000 population after age 65 HF is the most common Medicare diagnosis-related group More dollars are spent for the diagnosis and treatment of HF than any other diagnosis by Medicare

4. ACC Guidelines Focus on : Prevention of HF Diagnosis and management of chronic HF in the adult.

5. Definition HF is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood.

7. Because not all patients have volume overload at the time of initial or subsequent evaluation, the term “heart failure” is preferred over the older term “congestive heart failure.” Use terms: Compensated Heart Failure: euvolemic Decompensated Heart Failure: fluid overload

8. Etiology For a substantial proportion of patients, causes are: Coronary artery disease Hypertension Dilated cardiomyopathy

14. New York Heart Association Classes NYHA I: no symptoms w/ physical activity, but known disease NYHA II: slight limitations, symptoms w/ normal activities, but able to walk 3 blocks NYHA III: symptoms w. minimal activity and marked limitation of activity NYHA IV: symptoms at rest and any activity

15. Stages of Heart Failure Designed to emphasize preventability of HF through treatment therapies. Designed to recognize the progressive nature of LV dysfunction.

16. Stages of HF   COMPLEMENT, DO NOT REPLACE NYHA CLASSES   NYHA Classes - shift back/forth in individual patient (in response to Rx and/or progression of disease)   Stages - progress in one direction due to cardiac remodeling

17. Stages of HF At Risk for Heart Failure: STAGE A High risk for developing HF STAGE B Asymptomatic LV dysfunction Heart Failure: STAGE C Past or current symptoms of HF STAGE D End-stage HF

22. Stage A: at risk for HF  Therapy Treat Hypertension Treat Hypertension Encourage Smoking cessation Encourage Smoking cessation Treat lipid disorders Treat lipid disorders Encourage regular exercise Encourage regular exercise Discourage ETOH, drugs Discourage ETOH, drugs Control Metabolic Syndrome Control Metabolic Syndrome ACE or ARB in appropriate patents for vasc dz or diabetes ACE or ARB in appropriate patents for vasc dz or diabetes

23. Stage B: Structural disease/No Sx  Therapy: All measures under Stage A All measures under Stage A ACE or ARB in appropriate patients ACE or ARB in appropriate patients Beta-blockers in appropriate patients Beta-blockers in appropriate patients ICDs in appropriate patients ICDs in appropriate patients

24. Stage C: Structural Disease with current or prior sx  Therapy: All measures under Stages A and B All measures under Stages A and B Routine Use Routine Use ACE, Beta-blockerACE, Beta-blocker Diuretics for fluid retentionDiuretics for fluid retention Selected Patients Selected Patients Aldosterone antagonistAldosterone antagonist ARBARB DigitalisDigitalis Hydralazine/nitratesHydralazine/nitrates Devices: BI-V, ICD Devices: BI-V, ICD

25. Stage D: refractory HF  Therapy All measures from stages A, B, C All measures from stages A, B, C Decision: Decision: Appropriate level of careAppropriate level of care Compassionate end-of-life careCompassionate end-of-life care TransplantTransplant Chronic Inotropes: neo, epi, dopamine.Chronic Inotropes: neo, epi, dopamine.

26. Devices  An implantable cardioverter-defibrillator (ICD) for secondary prevention to prolong survival in patients with a history of cardiac arrest, ventricular fibrillation, or hemodynamically destabilizing ventricular tachycardia.

27. Devices  An ICD for primary prevention to reduce total mortality by preventing sudden cardiac death (SCD) in patients with ischemic heart disease who meet the following criteria: at least 40 days post-myocardial infarction, an LVEF 30 percent, New York Heart Association functional class II or III symptoms despite optimal chronic medical therapy, and a reasonable expectation of survival with a good functional status for more than one year.

28. Devices  An ICD for primary prevention to reduce total mortality by preventing SCD in patients with nonischemic cardiomyopathy who meet the following criteria: an LVEF less than 30 percent, New York Heart Association functional class II or III symptoms despite optimal chronic medical therapy, and a reasonable expectation of survival with a good functional status for more than one year.

29. Devices  Cardiac resynchronization therapy, unless contraindicated, in patients who meet the following criteria: cardiac dyssynchrony as defined by a QRS duration >120 msec, LVEF 35 percent, sinus rhythm, and New York Heart Association functional class III or ambulatory class IV symptoms despite optimal chronic medical therapy.
