HEART FAILURE MORTALITY
Death frequently occurs in elderly people
92 of general mortality has been observed in
patients over 65 years.
6
HEART FAILURE
HF is a complex clinical syndrome that can
result from any cardiac disorder impairing the
ability of the ventricle to eject blood or to
fill with it Heart is not able to satisfy
metabolic needs of the body, Or it does it with
an increased ventricular filling pressure (That
is with an increased work).
Reduced cardiac output reduced ejection
fraction (EF lt35-40)

9
Types of heart failure
Depending on heart function mainly impaired,
HEART FAILURE can be divided into
Systolic heart failure
Diastolic heart failure
10
EJECTION FRACTION
Echocardiographic parameter expressing the pump
function
EF systolic volume / tele-diastolic volume
x 100
regular EF gt40-60
11
Systolic heart failure
  • Stroke volume
  • Ejection fraction
  • Cardiac output

REDUCTION
12
Diastolic Heart Failure

Difficult filling of the
ventricle EF is normal or mildly
reduced
13
Two types of HF
Most common form of heart failure.
Systolic heart failure
More frequent in women, elderly, hypertensives
Diastolic heart failure
Sometimes they can coexist deficit of the pump
function AND ventricular filling phase impairment
Systo-diastolic heart failure
14

Reduced Tolerance to maximal exercise
16
Heart Failure signs and symptoms
  • Dyspnoea

Hepatomegaly
Tachycardia
Hypotension
Asthenia (Severe stage)
Peripheral Oedema
17
New York Heart Association (NYHA) classification
18
Compensatory mechanism (short term)
Vasoconstriction maintain organ perfusion
19
COMPENSATORY MECHANISMS in the long time...
become toxic to the myocardium
20
Compensatory mechanism (long term)

Salt and water retention pulmonary
congestion
Vasoconstriction exacerbates pump dysfunction,
increase afterload and hypoperfusion
Sympathetic activation increase energy
expenditure
21
COMPENSATORY MECHANISMS IN HEART FAILURE
Difficulty of the heart in pumping the blood
Blood peripheral perfusion reduction
Renal hypoperfusion
Baroceptors Activaction (cardiac chambers,
carotid sinus, aortic arch )
Renin release
Aldosterone
Angiotensin II
Sympathetic activation
Peripheral resistance increase
Volemia increase
Tachycardia positive inotropic effect
Pump function restoring

25
DIURETICS
Therapy
  • Mainly used to reduce water retention symptoms
    (peripheral oedema and pulmonary congestion).
  • They rapidly improve dyspnoea and maximal
    exercise tolerance
  • No evidence in reducing mortality.

VASODILATORS
  • They reduce cardiac work (after-load)
  • No evidence in reducing mortality.

26
Drugs used in the treatment of HF
27
HEART FAILURETREATMENT
  • Diuretics in patients with water retention
  • ACE inhibitors (ARB, if intolerant)
  • Beta blockers (if not contraindicated)
  • Digitale (if not contraindicated)
  • Aldosterone Antagonists(Spironolactone) in
    patients with preserved renal function, normal
    kaliemia and recent symptoms/ NYHA IV class

Hunt SA et al. J Am Coll Cardiol. 2001 38 2101
28
Beta-blockers
exert a protective effect on the heart since
they prevent the damage to myocardial cells
caused by catecholamines reduce the work of
heart and its oxygen consumption decrease the
probability of arrhythmias directly and
indirectly prevent the mechanism leading to left
vetricular remodelling
29
Guidelines for the diagnosis and treatment of
chronic heart failure executive summary (update
2005)
ACE-I are recommended as 1st line therapy in pts
with a reduced LVEF,(lt40-45) with or without
symptoms. BB should be considered for the
treatment of ALL PATIENTS (NYHA II-IV), WITH
MILD/ MODERATE/SEVERE HF from ischemic/Non
ischemic cardiopathy on standard treatment,
unless theres a contraindication
30
Guidelines for the diagnosis and treatment of
chronic heart failure executive summary (update
2005)
Beta Blockers
  • Hospitalizations reduction, symptoms and exercise
    capacity improvement, slowing progression of
    heart failure, survival improvement.
  • Starting with low dosage
  • To reach gradually the maximum dose tolerated.
  • To add to the therapy with ACE - I and Diuretics

HEART FAILURE IN ELDERLY
Progressive aging of the population
Currently the greatest percentage of CHF
patients is represented by the ELDERLY.
However, current therapy of CHF is based on
evidence obtained from trials performed in
younger patients

Nebivolol significantly improves LVEF and didnt
change the QoL of elderly CHF patients
LVEF can be considered a reliable surrogate
parameter to evaluate the therapy in CHF.

Why Nebivolol in CHF?
Highly cardio-selective Physiological
vasodilation (NO mediated) Positive
effect on endothelial function Tzemos,
Circulation 2001104511

50
NEBIVOLOL
Pharmacodynamic properties In hypertensive
patients during acute or chronic treatment with
nebivolol systemic vasal resistances decrease.
Cardiac output with Nebivolol, despite the
Heart Rate reduction, remains preserved at rest
or during maximal exercise thanks to the increase
of the stroke volume
51

Nebivolol in HF
  • elderly patients
  • men and women
  • moderate low EF
  • associate conditions
  • (systolic HTN, PAD)

SENIORS type patients
NEBIVOLOL
90
Guidelines for the diagnosis and treatment of
chronic heart failure (update 2005)
  • Treatment of congestive heart failure in elderly
    patients - Beta blockers
  • With the exclusion of patients with such
    contraindications as sick sinus node, AV- block,
    COPD, beta blockers are well tolerated in elderly
    patient.
  • Treatment with beta blockers should not be
    exclusively suspended because of elderly age of
    the patients

91
Guidelines for the diagnosis and treatment of
chronic heart failure (update 2005)
  • Beta blockers
  • In Heart Failure patients, different molecules
    of beta blockers could bring different clinical
    benefits. Thus, only bisoprolol, carvedilol,
    metoprolol succinate and nebivolol should be
    recommended (Class of recommendation I, level of
    evidence A)

92
Conclusions
Nebivolol significantly reduced death or
hospitalisation in elderly heart failure
patients The effect was statistically independent
of ejection fraction, age or gender The 10 mg
dose was well tolerated and demonstrated larger
beneficial effects In comparing like for like
patients Nebivolol appears to be at least as
effective as metoprolol CR, bisoprolol or
carvedilol
93
Conclusions
Nebivolol was well tolerated, 68 pts received
10 mg daily dose for a mean period of 18
months The safety profile of nebivolol almost
overlapped that of placebo in terms of incidence,
type, severity
