Patient presentation

Patient Presentation

  • Mr. Smith is a 67 yo male with a history of hypertension and diabetes who now presents to your clinic with mild dyspnea at the end of his 1 mile walk. No chest pain. He has occasional pedal edema.

  • VS – stable

  • Lungs – CTA, normal work of breathing

  • CV – RRR, nl S1 S2, no MRG heard

  • Extremities - 1-2+ pitting edema.

  • Where do you go from here?


Pre lecture needs assessment

Pre-lecture Needs Assessment

  • What are the four NYHA classes of HF?

  • What are the four ACC stages of HF?

  • Which medication classes are routinely prescribed in heart failure?

  • Which three beta-blockers are approved to treat HF?


Define heart failure

Define Heart Failure

  • “Heart failure is a complex syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood.” 1

  • The cardinal symptoms are dyspnea and fatigue, while the predominant clinical sign is fluid retention (rales, elevated jugular venous pulsations, and pedal edema). Given that not all patients are volume overloaded at the time of diagnosis (diastolic dysfunction), the term “heart failure” is now preferred over “congestive heart failure.”

1Hunt S, et al, ACC/AHA Guidelines for the Evaluation and Management of Chronic Heart Failure in the Adult: A Report of the American College of Cardiology/American Heart

Association Task Force on Practice Guidelines (Committee to Revise the 1995 Guidelines for the Evaluation and Management of Heart Failure). 2001, ACC web site, accessed November 12, 2004.


Epidemiology of heart failure

Epidemiology of Heart Failure

  • Approximately 5 million patients in the USA have HF, with a yearly incidence of close to 500,000.

  • It is primarily a disease of the elderly, with 6-10% patients over 65 years old being diagnosed with HF.

  • 80% of hospitalized patients with HF are > 65yo.

  • Heart failure is the most common Medicare DRG.


Epidemiology of heart failure1

Epidemiology of Heart Failure

  • “…one-year mortality of approximately 45 percent.” 2

  • “Survival ranges from 80% at 2 years for patients rendered free of congestion to less than 50% at 6 months for patients with refractory symptoms.” 3

3 Nohria A, et al, Medical Management of Advanced Heart Failure, JAMA, 287(5): 628-40, 2002.


Epidemiology of heart failure2

Epidemiology of Heart Failure

  • “Heart failure admission rates are rising, and the prognosis of heart failure has been compared with that of malignancy, with a 6-year mortality rate of 84% in men and 77% in women.” 4

  • Heart failure kills people much more surely than most cancers!

  • Coronary artery disease is the cause of two thirds of left ventricular systolic dysfunction

4 Mair F, et al, Evaluation of suspected left ventricular systolic dysfunction, JFP, 51(5): 466-71, 2002.


Diagnosing heart failure symptoms

Diagnosing Heart FailureSymptoms

  • Decreased exercise tolerance

  • Fluid retention

  • Fatigue

  • Incidentally noted left ventricular dysfunction in an asymptomatic patient


Diagnosing heart failure clinical signs

Diagnosing Heart FailureClinical Signs

  • Elevated jugular venous pressure

  • Pulmonary rales

  • S3

    • S3 – volume overload

    • S4 – pressure overload

  • Peripheral edema

Diagnosing heart failure

Diagnosing Heart Failure

  • Many different terms:

  • Left vs right-sided failure

  • Backward vs forward failure

  • Volume vs pressure overload

  • Systolic vs diastolic dysfunction – there is a lot of overlap as many patients have aspects of both entities


Echocardiography

Echocardiography

  • A generally accepted definition of depressed systolic function is an ejection fraction < 40%, from the ACC guideline on the use of echocardiography.

  • Note that this is not a useful definition in diastolic dysfunction as the EF may actually be increased in diastolic dysfunction.


Heart failure stages vs nyha classes

Heart Failure Stages vsNYHA Classes


Stages of heart failure

Stages of Heart Failure


Heart failure treatment options

Heart Failure Treatment Options

  • Angiotensin Converting Enzyme Inhibitors (ACEIs)

  • Beta-blockers

  • Diuretics

  • Digoxin

  • Angiotensin Receptor Blockers (ARBs)

  • Other medications


Site of action of medications

Site of Action of Medications


Aceis

ACEIs


Aceis1

ACEIs

  • They are the most studied class with years of experience and large patient numbers in RCTs. Proven benefit to decrease mortality and hospitalization for HF.


Aceis2

ACEIs

  • A comparison of enalapril with hydralazine-isosirbide dinitrate in the treatment of chronic congestive heart failure.

  • 804 men on digoxin and diuretics were randomized to receive enalapril or hydralazine and isosorbide dinitrate. The enalapril arm demonstrated an 18% mortality rate at 2 years compared with 25% for the hydralazine and isosorbide dinitrate arm.

  • Cohn JN, NEJM, 325(5): 303-10, 1991


Aceis what dose

ACEIs – what dose?

  • ATLAS: Patients with NYHA class II to IV with and EF< or = 30% were assigned to either low dose (2.5 – 5.0mg) or high dose (32.5 – 35mg) of lisinopril for up to five years. Patients on the higher dose had a nonsignificant decrease in mortality of 8% with a significant 12% decrease in death or hospitalization for any reason, as well as 24% fewer hospitalizations for heart failure.

  • Packer M, Circulation, 100(23): 2312-8, 1999


Aceis what dose1

ACEIs – what dose?

  • Outcome of patients with congestive heart failure treated with standard versus high doses of enalapril: a multicenter study.

  • There were no differences in mortality or hospitalizations between patients treated with up to 20 mg or those treated with up to 60 mg of enalapril.

  • Nanas J, JACC, 36: 2090-5, 2000.


Aceis3

ACEIs

  • HOPE Trial: The use of ramipril in patients with multiple cardiac risk factors without known CHF or left ventricular dysfunction reduces the risk of death from any cause, MI, stroke, and heart failure.

  • HOPE investigators, NEJM, 342(3): 145-153, 2000

  • Consider in patients with Stage A Heart Failure


Beta blockers

Beta-blockers


Beta blockers1

Beta-blockers

  • Beta-1 selective = metoprolol and bisoprolol

  • Alpha-1 and beta-nonselective = carvedilol.

  • Beta-blockers reduce the risk of death and the hospitalization. All three have shown benefit.


Beta blockers2

Beta-blockers

  • US Carvedilol Heart Failure Study Group: Carvedilol was added to background therapy of ACEI, diuretics, and digoxin. Patients receiving carvedilol experienced a 65% decrease in mortality, a 27% decrease in hospitalizations, and a 38% decrease in the combination of the two.

  • Packer M, NEJM, 334(21): 1349-55, 1996.


Beta blockers3

Beta-blockers

  • CIBIS-II: Bisoprolol was added to standard therapy (diuretics and ACEIs) in patients with NYHA III or IV with EF < 35%. Study was stopped early because of the benefit. The hazard ratio of death was 0.56 vs placebo.

  • Anon., Lancet, 353(9146): 9-13, 1999.


Beta blockers4

Beta-blockers

  • MERIT-HF: Patients had NYHA class II to IV, an EF<40%, and were stabilized with optimum medical therapy. Patients were randomized to receive the beta-1 blocker metoprolol CR/XL. Patients in therapy experienced a 19% decrease in mortality or all-cause hospitalizations and a 31% decrease in HF hospitalizations.

  • Hjalmarson A, JAMA, 283(10): 1295-1302, 2000.


Beta blockers5

Beta-blockers

  • CAPRICORN: Effect of carvedilol on outcome after myocardial infarction in patients with left-ventricular dysfunction: the CAPRICORN randomized trial.

  • 1959 patients post MI with EF<40% were randomized to carvedilol or placebo. All-cause (ARR 3%) and cardiovascular mortality, as well as non-fatal MI were reduced in patients on carvedilol.

  • Dargie H, Lancet, 357(9266): 1385-90, 2001.


Beta blockers6

Beta-blockers

  • COPERNICUS: Effect of carvedilol on the morbidity of patients with severe chronic heart failure: results of the carvedilol prospective randomized cumulative survival study.

  • 2289 patients with severe heart failure (EF<25%) were randomized to receive carvedilol or placebo for an average of ten months. Mortality from cardiovascular causes and heart failure mortality or hospitalization were both decreased by 27% and 31% respectively. In euvolemic patients with symptoms at rest or on minimal exertion, the addition of carvedilol to conventional therapy ameliorates the severity of heart failure and reduces the risk of clinical deterioration, hospitalization, and other serious adverse clinical events.

  • Packer M, Circulation, 106(17):2194-9, 2002.


Beta blockers7

Beta-blockers

  • COMET: Comparison of carvedilol and metoprolol on clinical outcomes in patients with chronic heart failure in the Carvedilol Or Metoprolol European Trial.

  • 1511 patients on standard HF therapy with EF<35% were randomized to receive carvedilol or metoprolol. After 5 years, all cause mortality was 34% with carvedilol and 40% with metoprolol. The composite endpoint of all-cause mortality and hospitalization was the same in both groups.

  • Poole-Wilson P, Lancet, 362(9377):7-13, 2003


Diuretics

Diuretics


Diuretics1

Diuretics

  • No dedicated RCTs to evaluate the use of loop diuretics. (Perhaps unethical now that their use is standard of care)

  • Diuretics are added when patients experience symptoms or signs of volume overload.


Diuretics2

Diuretics

  • Furosemide (Lasix) usually the first line, although HCTZ could be used.

  • Only loop diuretics are effective when the CrCl drops below 30cc/min.


Diuretics and the neurohormonal basis of heart failure

Diuretics and the neurohormonal basis of heart failure

  • RALES Trial: Spironolactone was added to therapy in patients with severe heart failure and an EF<35% being treated with ACEIs, diuretics, and (in most cases) digoxin. The study was stopped early after demonstrating an absolute decrease in mortality of 11% (RR = 0.70) and an relative decrease in hospitalization of 35% (RR = 0.65). 10% of males had gynecomastia or mastalgia. Minimal hyperkalemia was reported.

  • Pitt B, NEJM, 341(10): 709-17, 1999.


Diuretics and the neurohormonal basis of heart failure1

Diuretics and the neurohormonal basis of heart failure

  • Ephesus trial - The use of eplerenone in patients post-MI who had an EF<40% and clinical signs of heart failure showed benefit. Patients on the medication experienced and absolute risk reduction in mortality of 2.3% (RRR = 14%).

  • Pitt B, et al. Eplerenone, a selective aldosterone blocker, in patients with left ventricular dysfunction after myocardial infarction. N Engl J Med, 348:1309-21, 2003.


Digoxin

Digoxin


Digoxin1

Digoxin

  • RADIANCE Study: Patients on a stable regimen of digoxin, ACEI, and diuretic were randomized to removal of digoxin or maintenance of therapy. Those patients off digoxin experienced a significant increase in worsening heart failure and decreased measures of functional capacity.

  • Packer M, NEJM, 329(1): 1-7, 1993.


Digoxin2

Digoxin

  • Digitalis Intervention Group: Patients on ACEI and diuretics were randomized to receive digoxin or placebo. Overall mortality was similar in both groups. However, digoxin did decrease the risk of worsening heart failure and hospitalization.

  • Rekha G, NEJM, 336(8): 525-33, 1997.


Update in heart failure july 12 2007

ARBs


Angiotensin receptor blockers arbs

Angiotensin Receptor Blockers (ARBs)

  • The ARBs – studies have shown that they have efficacy close to that of ACEIs.

  • ARBs are frequently used in patients who cannot tolerate ACEIs (cough, h/o angioedema).

  • They are expensive.


Update in heart failure july 12 2007

ARBs

  • ELITE: Evaluation of losartan in the elderly. 722 patients older than 65 with EF<40% and ACEI naïve were randomized to losartan or captopril, in addition to standard therapies (ACEIs, diuretics, digoxin, nitrates and hydralazine). Patients on losartan has less side effects, a nonsignificant decrease in death and/or hospital admission for heart failure, and a significant decrease in all-cause mortality (risk reduction = 46%). Admissions for heart failure were the same in both groups.

  • Pitt B, Lancet, 349(9054): 747-52, 1997


Update in heart failure july 12 2007

ARBs

  • ELITE-II: Effect of losartan compared with captoril on mortality in patients with symptomatic heart failure: a randomized trial – the Losartan Heart Failure Survival Study. 3152 patients 60 years or older with NYHA class II to IV heart failure and EF<40% were randomized to losartan or captopril. The mortality and rates of sudden death or resuscitated arrests were the same in both groups.

  • Pitt B, Lancet, 355(9215): 1582-7, 2000


Update in heart failure july 12 2007

ARBs

  • LIFE trial: Hypertensive patients were treated with either losartan or atenolol. Patients were followed for at least four years. 508 patients on losartan experienced the composite endpoint of death, MI, or stroke, compared with 588 patients on atenolol (RR = 0.87).

  • Dahlof B, Lancet, 359(9311): 995-1003, 2002.


Update in heart failure july 12 2007

ARBs

  • Val-HeFT: A randomized trial of the angiotensin-receptor blocker valsartan in chronic heart failure. 5010 patients with NYHA class II to IV HF were randomized to receive valsartan or placebo in addition to standard therapy. Overall mortality was the same. Hospitalizations were 4.4% less. Treatment with valsartan improved NYHA class, EF, signs and symptoms of HF, and quality of life. Post hoc analysis showed the valsartan had a favorable outlook in patients receiving ACEI or beta-blockade but an adverse effect in patients receiving both.

  • Cohn J, et al, NEJM, 345(23): 1667-75, 2001


Update in heart failure july 12 2007

ARBs

  • CHARM-Alternative Trial (Candesartan substituted for ACEI in ACEI intolerant patients).

  • 2028 patients with symptomatic heart failure and EF<40% were randomized to candesartan or placebo, in addition to standard therapy. After 3 years, cardiovascular mortality and hospital admissions for CHF were both less (3% and 8% absolute risk reduction).


Update in heart failure july 12 2007

ARBs

  • CHARM-Added Trial

  • In this trial, 2548 patients taking ACEIs with a decreased EF<40% were randomized to receive candesartan or placebo in addition to the ACEI.

  • Cardiovascular and noncardiovascular mortality were reduced significantly in the candesartan group (ARR = 4%, RRR = 10%), as were hospitalizations.


Update in heart failure july 12 2007

ARBs

  • CHARM-Preserved Trial: Candasartan in Heart failure Assessment of Reduction in Mortality and morbidity study. (A trio of trials.)

  • In this trial, 3023 patients with a preserved EF>40% were randomized to receive candesartan or placebo. Cardiovascular and noncardiovascular mortality were the same in both groups, while hospitalizations were modestly decreased.

  • Yusuf S, Lancet, 362: 777-81, 2003.


Update in heart failure july 12 2007

ARBs

  • VALIANT trial – valsartan is as effective as captopril post-MI in patients with decreased EF.

    • Pfeffer MA et al, NEJM, 349: 1893-906, 2003

  • RESOLVD trial – candesartan with enalapril and ER metoprolol demonstrated the most improvement in EF from baseline. No clinical outcomes.

Cibis iii

CIBIS III

  • In general, beta-blockers are considered as add-on therapy to patients already on ACEIs and diuretics.

  • What are the beta-blockers that have proven efficacious for HF?


Update in heart failure july 12 2007

  • Carvedilol (Coreg)

    • 6.25 – 25 mg bid, start at 3.125mg bid and titrate every 2 weeks

  • Metoprolol (Lopressor, Toprol XL)

    • Metoprolol XL is the drug that has been studied

    • Toprol XL 12.5 – 200 mg qday

    • Metoprolol 50 – 200mg bid – not FDA approved

  • Bisoprolol (Not FDA approved)

    • Zebeta 2.5 - 20 mg qday and generic at same doses

    • Bisoprolol/HCTZ is Ziac – 2.5/6.25, 5/6.25, 10/6.25

      • One tab qday


Cibis iii1

CIBIS III

  • 1010 treatment naïve patients with mild to moderate heart failure and EF <35% randomized to open-label monotherapy with bisoprolol (10mg qday) or enalapril (10mg bid) for six months. Then the two were combined for 6 to 24 months.

  • Study end-points:

    • All-cause mortality

    • Hospitalization


Cibis iii2

CIBIS III

  • In the per-protocol study:

    • Bisoprolol first – 163 patients had a primary end point

      • Of these, 65 died

    • Enalapril first – 165 patients had a primary end-point

      • Of these, 73 died

  • -0.7% absolute difference in patients having a primary end point

    • What is the NNT? There is a nice reward for this

  • Hazard ratio of 0.88 of death

  • Hazard ratio of 0.95 of hospitalization


Summary points

Summary Points

  • Heart failure has a prognosis similar to that of cancer. As such, treat it aggressively.

  • There is a new staging system to classify heart failure:

    • Stage A – at risk but no structural heart disease (HD)

    • Stage B – no symptoms but structural HD present

    • Stage C – patient with symptomatic HF

    • Stage D – refractory heart failure


Summary points1

Summary Points

  • Standard medication classes for HF include:

    • ACEIs

    • Beta blockers

    • Diuretics if volume overloaded

    • Consider digoxin, spironolactone

    • Consider ARBs, especially in ACEI intolerant patient

  • Beta-blockers continue to look good for HF


Summary points2

Summary Points

  • Preserved EF is about as common as depressed EF in heart failure.

  • Many patients have diastolic dysfunction.

  • Remember to also care for the patient as a person, not just a disease.

  • A gentle touch and a kind smile might feel better than a lasix-induced diuresis 

Trends in prevalence and outcome of heart failure with preserved ejection fraction

Trends in Prevalence and Outcome of Heart Failure with Preserved Ejection Fraction

  • 4596 patients admitted to Mayo Clinic Hospitals from 1987 to 2001.

  • 53% had reduced ejection fraction

  • 47% had preserved ejection fraction

  • Survival was slightly better among those with preserved EF – adjusted hazard ration for death = 0.96, p = 0.01.

Preserved Ejection Fraction, NEJM, 355:3, July 20, 2006, pp 251-259


Take home points

Take home points

  • Starting with an ACEI is still standard of care.

  • However, future studies with FDA approved drugs for heart failure in the USA may confirm that beta-blockers are equally efficacious (noninferior) to ACEIs for the initial treatment of HF.

Outcome of Heart Failure with Preserved Ejection Fraction in a Population-Based Study

  • 2802 patients admitted to 103 Canadian hospitals from April 1999 to March 2001 with a discharge diagnosis of heart failure.

  • 31% had ejection fraction (EF) > 50%

  • More likely to be older, female, history of HTN, history of atrial fibrillation

Outcome of Heart Failure with Preserved Ejection Fraction in a Population-Based Study

  • Mortality rate of preserved EF (>50%) vs reduced EF (<40%) at 30 days

    • 5% vs 7% respectively

  • At one year, the rates were 22% vs 26%, p=0.07, not significantly different.

  • Patients with preserved EF have similar rates for mortality and readmission for heart failure

  • Interesting outcomes

  • Lower systolic at admission directly correlated with increased mortality

  • Concept of the “J” curve in treatment of hypertension

  • So, what systolic blood pressure do we shoot for in patients with stable heart failure in the clinic?

  • Still use national guidelines but stay tuned

  • Inpatients and outpatients diagnosed with heart failure underwent echocardiographic testing between September 10, 2003 and October 27, 2005.

  • 556 study participants

  • Preserved EF > 50 % present in 308 (55%) of patients

    • Associated with older age, female sex, no h/o MI

    • Isolated diastolic dysfunction present in 242 of patients of these patients – 44% of total number (556) and 78% of patients with preserved EF

  • EF < 50% in 248 patients (45%)

    • Diastolic dysfunction present in 204 (83%) of these patients

Systolic and Diastolic Heart Failure in the Community

  • Needham’s take on this data…

  • A little more than half (55%) of patients had preserved EF at the time of diagnosis of heart failure.

  • Almost 80% of all patients with heart failure have diastolic dysfunction, whether they have depressed or preserved EF.

  • Many patients will have a mix of systolic dysfunction (depressed EF) and diastolic dysfunction.
