Epidemiology of Heart Failure• Lifetime risk: 20% for Americans >40 years of age• 20 per 1,000 individuals age 65-69• >80 per 1,000 individuals age 85+
• 5.1 million Americans with clinical heart failure• >650,000 new cases diagnosed annually• Incidence has remained stable over last several decades
• Relative Risk (NHANES I)• Coronary Heart Disease: RR: 8.1• Diabetes: RR: 1.9• Cigarette Smoking: RR: 1.6• Hypertension: RR: 1.4• Obesity: RR: 1.3 9
2013 ACCF/AHA Guideline for the Management of Heart Failure. Circulation. 2013;128:1810-1852
Pathophysiology• Complex clinical syndrome resulting from structural or
functional impairment of ventricular filling and the ejection of blood
• Symptoms include:• Dyspnea• Fatigue• Fluid retention
• No single diagnostic test
10
Causes of Heart Failure• Cardiac Disorders• Pericardium• Myocardium• Endocardium• Heart Valves
• Impaired left ventricular function• Cardiomyopathy• Dilated ventricle• Hypertrophic ventricle
• Impaired Ejection Fraction• Heart Failure with Preserved Ejection Fraction• Heart Failure with Reduced Ejection Fraction 13
2013 ACCF/AHA Guideline for the Management of Heart Failure. Circulation. 2013;128:1810-1852
Real Causes of Heart Failure• Ischemic Heart Disease• Majority of cases (50-60%)• Acute myocardial infarction
• Hypertension• Present in 70-80% of patients• Suspected etiology in 30-40% of cases
• Idiopathic dilated cardiomyopathy• 5-10% of patients
• Other cardiomyopathy causes• EtOH, drug induced

Staging of Heart Failure• American College of Cardiology Foundation/ American Heart
Association (ACCF/AHA)• Emphasize progression of disease• Useful for describing individuals and populations
• New York Heart Association (NYHA)• Focuses on exercise capacity and symptomatic status of disease
ACCF/AHA Stage NYHA Functional Classification
A: At risk for HF. No structural disease or symptoms
None
B: Structural Disease. No signs or symptoms I: Asymptomatic HF. No symptoms
C: Structural Disease. Prior or current symptoms II: Mild. Symptomatic with moderate exertionIII: Moderate. Symptomatic with mild exertion
D: Refractory HF requiring specialized interventions
IV: Severe. Symptomatic at rest15
Stage Management
Stage A
• At Risk for Heart Failure
Stage B
• Structural Heart Disease
Stage C
• Prior or Current Symptoms
Stage D
• Refractory Heart Failure16
“A” as in All Right• Stage A • At risk for HF. No structural disease or symptoms
• Manage patients risk factors• Hypertension
• Thiazide diuretics• ACE Inhibitors
• Hyperlipidemia• Lifestyle changes• Statins
• Control/avoid conditions that may lead to HF• Obesity• Diabetes mellitus• Tobacco use• Use of known cardiotoxic agents
17
“B” as in Better Treat• Stage B• Structural Disease. No signs or symptoms• Often a patient with recent or remote MI or ACS
• Initiate ACE Inhibitor• Prevent progression to symptomatic HF• Reduce mortality• ARB for ACEI intolerant • In ALL patients with reduced ejection fraction
• Initiate Beta Blocker• Approved beta blockers
• Metoprolol• Carvedilol• Bisoprolol
• Reduce mortality• In ALL patients with reduced ejection fraction
18
Stage B Cont.• Start a Statin• In all patients with history of MI or ACS
• Control Hypertension• Prevent LV hypertrophy
• Avoid Nondihydropyridine Calcium Channel Blockers• Diltiazem• Verapamil• Harmful in asymptomatic patients
19
“C” as in Symptomatic• Stage C• Structural Heart Disease. Prior or current symptoms• Recommendations added to Stage B
• Non-Pharmacologic Interventions• Patients should be educated about self care• Exercise training for those able• Sodium restriction• Continuous positive airway pressure
20
Class C Cont.• Diuretic Therapy• Loop diuretics• Patients with reduced ejection fraction• Symptomatic improvement
• Aldosterone Antagonist• NYHA II-IV• Reduced ejection fraction
• ACE Inhibitor + ARB• Persistently symptomatic• Those unable to use aldosterone antagonist
21
Class C Cont.• Hydralazine and Isosorbide Dinitrate• African Americans• NYHA III-IV on optimal therapy
• Digoxin• Beneficial in reduced ejection fraction• Reduce hospitalization
22
“D” as in Dyspnea at Rest• Stage D• Refractory heart failure• Specialized interventions

23
What’s New?• GDMT (guideline-directed medical therapy)• No longer “optimal medical therapy”• ACEI’s, BBs
• Patient Education• Balanced view of sodium restriction• No strong evidence• May be beneficial in volume overloaded patients
• Expanded use of aldosterone antagonists• Expanded use of MSC (mechanical circulatory support)• Intensified diuretic use in acute exacerbations

all patients with HF• Dietary sodium restriction (2-3 g daily) is recommended for
patients with the clinical syndrome of HF• New Guidelines:• Sodium restriction is reasonable for patients with symptomatic
HF to reduce congestive symptoms• Widely Embraced Idea• Not well supported by evidence• Particularly its effect on mortality

27
Kirklin J, Naftel D. Circulation. 2008 bio.felk.cvut.cz
Intensified Diuretics• Previous Guidelines:• When congestion fails to improve in response to diuretic therapy,
the following options should be considered:• Re-evaluating presence/absence of congestion• Sodium and fluid restriction• Increasing doses of loop diuretic• Continuous infusion of a loop diuretic • Addition of a second type of diuretic orally or intravenously
• New Guidelines:• Patients should be promptly treated with intravenous loop diuretics
to reduce morbidity• Dose should equal or exceed their chronic oral daily dose• Be given as either intermittent boluses or continuous infusion• Add a second (thiazide) diuretic• Low-dose dopamine infusion may be considered
