Heart Failure Definition• 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.
• Cardinal manifestations are dyspnea and fatigue (which may limit exercise tolerance), and fluid retention (which may lead to pulmonary congestion and peripheral edema).
• Both abnormalities can impair the functional capacity and quality of life of affected individuals, but they do not necessarily dominate the clinical picture at the same time.

• Some patients have exercise intolerance but little evidence of fluid retention, whereas others complain primarily of edema and report few symptoms of dyspnea or fatigue.
• 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.”
• One line definition: LV EDP > 12 mmHg

Refractory end-stage HFD
• Known structural heart disease• Shortness of breath and fatigue• Reduced exercise tolerance
Symptomatic HFC
• Previous MI• LV systolic dysfunction• Asymptomatic valvular disease
Asymptomatic HFB
• Hypertension• CAD • Diabetes mellitus• Family history of cardiomyopathy
High risk for developing heart failure (HF)A

Management of Chronic HF• Establish diagnosis (BNP, echo)• Determine etiology• Define syndrome (e.g. systolic vs. diastolic)• Correct precipitating factors (NSAIDS, COX2, etc.)• Evaluate and correct ischemia• Initiate chronic therapy
• Nonpharmacologic (e.g. exercise, tx. of sleep apnea, etc)• Pharmacologic (ACE - I, b - Blockers, ARB, diuretics, digoxin, etc.)• Electrical• Surgical
• Assess response to therapy

Stage C: Symptomatic HFClass I• Level A evidence
– Diuretics in patients with fluid retention
– ACE inhibition, unless contraindicated
– Beta blockade in stable patients, unless contraindicated
– Digitalis, unless contraindicated
• Level B evidence– Withdrawal of drugs known to adversely affect the clinical status of patients

Diuretics• Loop diuretics in pts. with CrCl < 30• Torsemide ↓ hospitalizations compared to furosemide• Have to be given bid to avoid rebound Na reabsorbtion• May use thiazides if CrCl > 30• Use combination (e.g. furosemide + thiazide), iv bolus
or iv drips• Metolazone in refractory HF or in pts. with renal
failure. Should not be used daily.• Add spironolactone if Cr < 2.5 and K < 5.

ACE Inhibitors• Most pts. tolerate ACE - I.• ACE - I improve symptoms immediately (days).• Pts. should not be “too dry” (no orthostatic ↓ BP).• If ↓ BP, check for orthostatic changes. If none, ACE - I OK.• Low BP and CRF are not CI for ACE - I.• If BUN/ Cr are raising, adjust the diuretic dose.• Low BP, low Na, renal dysfunction: low dose, short acting
ACE - I, titrate to target dose or the highest dose tolerated.• Low vs. high dose ACE - I: difference in outcomes.

Beta - Blockers• Only bisoprolol, carvedilol and metoprolol succinate.• Start at low doses, increase every 2 weeks to target dose or the
highest tolerated dose.• Intermediate vs. high dose: no difference in outcomes.• Do not start in pts. dependent of inotropic support.• Can start before hospital discharge in pts. not fluid overloaded.• Do not stop BB in hospitalized pts. who are on chronic BB

• Combination ARB + ACE - I + Beta - Blockers is safe.
• No mortality benefit when ARB is added to ACE - I.
• ARB are useful in pts. who are ACE intolerant.
• ARB could be added to ACE - I for symptomatic improvement.
• Triple RAAS blockade (ACE - I, ARB, aldosterone blockers) should not be used (Hyper K).

Recommendation for Diastolic HF• Control of systolic and diastolic BP.
• Control ventricular rate in pts. with A Fib.
• Diuretics to control pulmonary and peripheral edema.
• Anticoagulation in pts. with A Fib.
• Coronary revascularization in pts. with CAD and ischemia.
• Restoration of sinus rhythm in pts. with A Fib.
• Addition of Beta - Blockers, ACE - I, ARB, or CCB to control HTN.
• ACE –Inhibitors, ARBs, digoxin to minimize HF symptoms.

CONCLUSIONS: Chronic HF• STAGE A (HTN, CAD or DM):
– Routine: ACE-I/ARB; selected pts. BB, statin, antiplatelets
• STAGE B (Asymptomatic structural heart disease):– Routine: ACE-I/ARB, BB; selected pts. statin, antiplatelets
• STAGE C (Symptomatic HF and low EF):– Routine: ACE-I/ARB, BB, Aldo blockers, diuretics, digoxin– Selected pts. CRT, ICD, Hy-ISDN
• STAGE C (Symptomatic HF and preserved EF):– Consider ACE-I/ARB, digoxin ?, BB, CCB, Aldo blockers.
• STAGE D (End-stage HF):– Referral to HF program for LVAD, OHT.
