Highest prognostic benefit but under utilised

Better tolerated than generally perceived

Few contraindication; severe bradycardia and high degree heart block

( pace maker), severe bronchospasm

Even severe chronic airway disease ( FEV1 < 1.0) could tolerate beta blockers (

preferably selective e.g.. Bisoprolol) with prognostic benefit even with small dose

Start low and go slow

Prepare the patient pharmacologically and mentally

◦ ( reduce other vasoactive if appropriate and motivate patient)

Start ≤10% of the maximum dose and increase every 7-14 days

Aim maximum tolerated dose within 12 weeks or less

Excessive reliance on specialist“Need specialist supervision”

Maximum dose of ACEI before β blocker

Poor patient preparation & motivation.

Medication error.

Permanent Treatment Withdrawal or dose reduction before other measures

Adverse effects, disease progression or just myth?

Bradycardia & conduction abnormalities

Worsening Heart failure

Dizziness ,Hypotension : Lethargy & malaise

Worsens airways disease ( COPD)

placebo trial , Carvedilol significantly reduced HR

The Effect of Carvedilol on Morbidity and Mortality in

Patients with Chronic Heart Failure; 1996

1. Consider Holter monitor

2. Reduce or stop digoxin & amiodarone ,ensure

Verapamil or diltiazem are discontinued

3. Consider PPM (particularly biventricular device if QRS

greater than 120 and advanced conduction disease

4. β Blocker at night

Adverse effects, disease progression or just myth?

COMET( Carvedilol versus Metoprolol)

At 4 months, mean decrease of systolic BP from baseline was 3–8 mm Hg (SD 17·4) in the carvedilol group and 2–0 mm Hg

Dizziness 0 3 (0.4)

Hypotension 1 (0.3) 2 (0.3)

No significant change in BP in either

group from baseline

2003

1. Give β blocker 2 hours before/after other vasoactive agents

2. Beta blocker at bedtime & ACEI/ARB in the a.m

3. Reduce diuretics or nitrates & even ACE Iprazosin (prostate)

4. Reduce beta-blocker dose only as last resortMotivate and wait as symptoms are often self-limiting

COPD

Chronic Heart FailureAHJ 2006

Majority of COPD dies from CV

disease & lung cancer related cause.

Despite clear benefit , beta blocker

under prescribed

Cardio selective β blockers, as a single

dose or chronic:

1. Produced no change in FEV1 or,

2. Respiratory symptoms

3. Do not affect the FEV1 treatment

response to beta2-agonists.

Even in subgroup participants with

severe COPD or for those with a

reversible obstructive component.

Salpeter et al; 2009

Withdrawal or reduction of beta blocker dose

Avoid dual renin angiotensin system (RAS) blockade, improve albuminuria but increased creatinine & dialysis without mortality benefit (Ontarget).

Long term , loosely supervised diuretics combination (loop, thiazide, spironolactone ).

Motivate your patient !! This medication will,

make you breath better, make your heart stronger, keep you out off hospital ,

LIVE LONGER

Motivate your patient !!

It may make you feel a bit tired and very occasionally dizzy but most of the time will improve if you continue and persist

22.4% of patients in the placebo arms develop symptoms of fatigue, and 33.5% developed

worsening dyspnea

Appropriate use of combinations therapy

Lower threshold for commencing beta blocker in heart failure

Managing side effects

Majority of COPD dies from CV disease & lung cancer related

cause.

Despite clear benefit , beta blocker under prescribed

20 RCTs have shown that use of cardio selective Beta

blockers do not lead to worsening symptoms or decrease in

FEV1 even with Severe COPD or reversibility

Tolerated dose in CIBIS II

patients may have been

influenced to some extent

to the physician's tolerability
