Heart Failure Prevention
A careful and thorough clinical assessment, with appropriate investigation for known or potential risk factors, is recommended in an effort to prevent development of LV remodeling, cardiac dysfunction, and HF.

HF Risk Factor Treatment Goals
Risk Factor Goal
Hypertension Generally < 130/80
Diabetes See ADA guidelines
Hyperlipidemia See NCEP guidelines
Inactivity 20-30 min. aerobic 3-5 x wk.
Obesity Weight reduction < 30 BMI
Alcohol Men ≤ 2 drinks/day, women ≤ 1
Smoking Cessation
Dietary Sodium Maximum 2-3 g/day

Prevention: ACEI and Beta Blockers
• ACE inhibitors are recommended for prevention of HF in patients at high risk for this syndrome, including those with:• Coronary artery disease• Peripheral vascular disease• Stroke• Diabetes and another major risk factor
• ACE inhibitors and beta blockers are recommended for all patients with prior MI

• Studied impact of beta blocker (carvedilol) on post-MI patients with LVEF ≤ 40% already receiving contemporary treatments, including revascularization, anticoagulants, ASA, and ACEI:• All-cause mortality reduced (HR = 0.077; p = 0.03)• Cardiovascular mortality reduced
(HR = 0.75; p = .024)• Recurrent non-fatal MIs reduced (HR =.59; p = .014)
Dargie HJ. Lancet 2001;357:1385-90
Heart Failure Patient Evaluation
• Recommended evaluation for patients with a diagnosis of HF:
• Assess clinical severity and functional limitation by history, physical examination, and determination of functional class*
• Assess cardiac structure and function
• Determine the etiology of HF
• Evaluate for coronary disease and myocardial ischemia
• Evaluate the risk of life threatening arrhythmia
• Identify any exacerbating factors for HF
• Identify co-morbidities which influence therapy
• Identify barriers to adherence and compliance
*Metrics to consider include the 6-minute walk test and NYHA functional class
Adams KF, Lindenfeld J, et al. HFSA 2006 Comprehensive Heart Failure Guideline. J Card Fail 2006;12:e1-e122
Evaluation: Follow Up Assessments
• Recommended Components of Follow-Up Visits
• Signs and symptoms evaluated during initial visit
• Functional capacity and activity level
• Changes in body weight
• Patient understanding of and compliance with dietary sodium restriction
• Patient understanding of and compliance with medical regimen
• History of arrhythmia, syncope, pre-syncope or palpitation
• Compliance and response to therapeutic interventions
• Exacerbating factors for HF, including worsening ischemic heart disease, hypertension, and new or worsening valvular disease
Adams KF, Lindenfeld J, et al. HFSA 2006 Comprehensive Heart Failure Guideline. J Card Fail 2006;12:e1-e122
Rationale for Evidence-Based Drug Selection in Heart Failure
• Within drug classes, agents may differ pharmacologically
• These pharmacological differences may translate into differences in clinical outcomes
• When multiple agents within a class produce discordant results on clinical outcomes, class effect cannot be presumed (e.g., -blockers)

Level of Evidence: B

Acute Decompensated Heart Failure: Treatment Goals for Hospitalized Patients
• Improve symptoms, especially congestion and low-output symptoms
• Optimize volume status• Identify etiology• Identify precipitating factors• Optimize chronic oral therapy; minimize side effects• Identify who might benefit from revascularization• Education patients concerning medication and HF
self-assessment• Consider enrollment in a disease management
program
Adams KF, Lindenfeld J, et al. HFSA 2006 Comprehensive Heart Failure Guideline. J Card Fail 2006;12:e1-e122
Overview of Treatment Options for Patients with Acute Decompensated HF
• Fluid and sodium restriction• Diuretics, especially loop diuretics• Ultrafiltration/renal replacement therapy
(in selected patients only) • Parenteral vasodilators *
(nitroglycerin, nitroprusside, nesiritide)• Inotropes * (milrinone or dobutamine)
*See recommendations for stipulations and restrictions.
Adams KF, Lindenfeld J, et al. HFSA 2006 Comprehensive Heart Failure Guideline. J Card Fail 2006;12:e1-e122
Discharge Criteria for Hospitalized ADHF Patients
• Recommended prior to discharge for all patients with HF:• Exacerbating factors addressed• Near optimum fluid status achieved• Transition from IV to oral diuretic completed• Near optimum pharmacologic therapy achieved• Follow-up clinic visit scheduled, usually 7-10 days
• Should be considered prior to discharge for patients with advanced HF or a history of recurrent admissions:• Oral regimen stable for 24 hours• No IV inotrope or vasodilator for 24 hours• Ambulation before discharge to assess functional
capacity• Plans for post-discharge management• Referral to a disease management program
Adams KF, Lindenfeld J, et al. HFSA 2006 Comprehensive Heart Failure Guideline. J Card Fail 2006;12:e1-e122
Predictors of Mortality Based on Analysis of ADHERE Database
• Classification and Regression Tree (CART) analysis of ADHERE data shows:
• Three variables are the strongest predictors of mortality in hospitalized ADHF patients:
BUN > 43 mg/dL
Systolic blood pressure < 115 mmHg
Serum creatinine > 2.75 mg/dL
BUN > 43 mg/dL
Systolic blood pressure < 115 mmHg
Serum creatinine > 2.75 mg/dL
Fonarow GC et al. JAMA 2005;293:572-80
Heart Failure Patient Education
• It is recommended that patients with HF and their family members or caregivers receive individualized education and counseling that emphasizes self-care.
• This education and counseling should be delivered by providers using a team approach.
• Teaching should include skill building and target behaviors

End-of-Life Care in Heart Failure
• End-of-life care should be considered in patients who have advanced, persistent HF with symptoms at rest despite repeated attempts to optimize pharmacologic and non-pharmacologic therapy, as evidenced by one or more of the following:
• Frequent hospitalizations (3 or more per year)• Chronic poor quality of life with inability to
accomplish activities of daily living• Need for intermittent or continuous intravenous
support• Consideration of assist devices as destination
therapy
