FORMS of TOBACCO
Cigarettes are, by far, the most common form of tobacco used in the U.S.
Other forms of tobacco exist, and some are increasing in popularity.
All forms of tobacco are harmful.
Attention to all forms of tobacco is needed.
CIGARS: 1950–2007U.S. CONSUMPTION
Data from U.S.D.A. (2004 & 2007)
One cigar can deliver enough nicotine to establish and maintain dependence
TOBACCO and SECOND-HAND SMOKE: CARDIOVASCULAR DISEASE RISK
HEALTH CONSEQUENCES of SMOKING
Cancers Acute myeloid leukemia Bladder and kidney Cervical Esophageal Gastric Laryngeal Lung Oral cavity and pharyngeal Pancreatic
Pulmonary diseases Acute (e.g., pneumonia) Chronic (e.g., COPD) Tuberculosis
Cardiovascular diseases Abdominal aortic aneurysm Coronary heart disease Cerebrovascular disease Peripheral arterial disease Sudden death Heart failure

Standard treatments reduce the risk of death in patients with CVD by 15–35% Aspirin = 15% Beta blockers = 23% ACE inhibitors = 23% Statins = 29–35%
Smoking cessation reduces the risk of death by 36% and reduces the risk of future cardiac events by 50%
TOBACCO CESSATION as TREATMENT for CVD
SUMMARY: REASONS to ADDRESS TOBACCO in CARDIOLOGY
Smoking and SHS act synergistically with other CVD risk factors
Smoking increases risk for surgical complications
Quitting smoking improves survival Quitting smoking improves quality of life Quitting reduces risk of future CVD events
TOBACCO CESSATION is an essential component of prevention and treatment for CVD.

NRT: PRECAUTIONS
Patients with underlying CVD: Recent MI (within past 2 weeks) Serious arrhythmias Serious or worsening angina
NRT may be appropriate for these patients if they are under medical supervision
Experts believe the risks of NRT in heart patients are small in relation to the risks of continued tobacco use.
TRANSDERMAL NICOTINE PATCH
DISADVANTAGES Patients cannot titrate
the dose Allergic reactions to
adhesive may occur Vivid/disturbing dreams
may occur with nocturnal patch use (can remove before sleep)
ADVANTAGES The patch
provides consistent nicotine levels
The patch is easy to use and conceal
Fewer compliance issues are associated with the patch
PATIENT EDUCATION :Nicotine Patch
Apply patch to hairless area—new location daily
Water will not harm the nicotine patch if it is applied correctly; patients may bathe, swim, shower, or exercise while wearing the patch
Do not cut patches to adjust dose Nicotine may evaporate from cut edges Patch may be less effective
Keep new and used patches out of the reach of children and pets
NICOTINE GUM & LOZENGE
DISADVANTAGES Gastrointestinal side
effects may be bothersome
Gum may be socially unacceptable and difficult to use with dentures
Patients must use proper chewing technique to minimize adverse effects
ADVANTAGES Patients can titrate
therapy to manage withdrawal symptoms
May satisfy oral cravings
May delay weight gain
NICOTINE GUM:
CHEWING TECHNIQUE SUMMARY
Park between cheek & gum
Stop chewing at first sign of peppery taste or tingling sensation
Chew slowly
Chew again when peppery taste or tingle fades
Do not eat or drink 15 min before or
after use.
NICOTINE INHALERDISADVANTAGES
Initial throat or mouth irritation can be bothersome
Cartridges should not be stored in very warm conditions or used in very cold conditions
Patients with underlying bronchospastic disease must use the inhaler with caution
ADVANTAGES Patients can easily
titrate therapy to manage withdrawal symptoms
The inhaler mimics hand-to-mouth ritual of smoking
NICOTINE NASAL SPRAY
DISADVANTAGES Nasal/throat
irritation may be bothersome
Dependence can result*
Patients must wait 5 min before driving or operating heavy machinery
* The data on higher dependence are not definitive and are based on small trials.
ADVANTAGES Most rapidly
absorbed form of nicotine replacement
Patients can easily titrate therapy to rapidly manage withdrawal symptoms
BUPROPION SRDISADVANTAGES Should be avoided in
patients with an increased risk for seizures
Side effects:Common: dry mouth, anxiety, insomnia (avoid bedtime dosing)
Less common: tremor, skin rash
ADVANTAGES Easy to use Can be used with
NRT or varenicline May delay cessation-
related weight gain May be beneficial in
patients with coexisting depression
BUPROPION: CONTRAINDICATIONS and PRECAUTIONS
History of seizure Current or prior eating disorder History of cranial trauma, stroke, or neurosurgical
intervention Treatment with medications that lower the seizure
threshold (e.g., antipsychotics, antidepressants, theophylline)
Treatment with MAOIs in the past 2 weeks Abrupt discontinuation of alcohol or sedatives
(including benzodiazepines) Severe hepatic cirrhosis
BUPROPION:MECHANISM OF ACTION
Atypical antidepressant thought to affect levels of various brain neurotransmitters Dopamine
Norepinephrine
Clinical effects craving for cigarettes
symptoms of nicotine withdrawal
BUPROPION SR: DOSING for SMOKING CESSATION
Initial treatment 150 mg po q AM x 3 days
Then, if tolerated… 150 mg po bid x 7–12 weeks
If 300 mg is not well tolerated… Reduce dose to 150 mg and reassure that
150 mg dose is still efficacious (Swan et al., 2003)
Patients should begin therapy one week PRIOR to quitting to assure therapeutic plasma levels
of drug are achieved when patient is no longer
smoking.
BUPROPION: ADDITIONAL PATIENT EDUCATION
Can be safely used with NRT or varenicline Dose tapering is not necessary when
discontinuing treatment If no significant progress toward abstinence
by 7th week, therapy is unlikely to be effective Discontinue treatment Reevaluate and restart at later date
FDA boxed warning added in July 2009
VARENICLINE
DISADVANTAGES Common side effects:
Nausea (in up to 33% of patients)
Sleep disturbances (insomnia, abnormal dreams)
Constipation Flatulence Vomiting
ADVANTAGES Oral formulation with
twice-a-day dosing Offers a new
mechanism of action for persons who previously failed using other medications
Early industry-sponsored trials suggest this agent is superior to bupropion SR
VARENICLINE:MECHANISM of ACTION
Binds with high affinity and selectivity at 42 neuronal nicotinic acetylcholine receptors Stimulates low-level agonist activity
Competitively inhibits binding of nicotine
Clinical effects symptoms of nicotine withdrawal
Blocks dopaminergic stimulation responsible for reinforcement & reward associated with smoking
VARENICLINE: DOSINGPatients should begin therapy 1 week PRIOR to
theirquit date. The dose is increased gradually to
minimize treatment-related nausea and insomnia.Treatment Day Dose
Days 1–3 0.5 mg qd
Days 4–7 0.5 mg bid
Day 8 – week 12 1 mg bid
Initial dose titration
VARENICLINE: ADDITIONAL PATIENT EDUCATION
Do not combine with NRT—increase in side effects, including nausea, headache, vomiting, fatigue
Doses should be taken after eating, with a full glass of water
Nausea and insomnia are side effects that are usually temporary
Dose tapering is not necessary when discontinuing treatment
FDA BOXED WARNINGS
On July 1, 2009, varenicline and bupropion received Boxed Warnings concerning the risk of serious neuropsychiatric symptoms:
Patients should be advised to stop taking varenicline or bupropion and to contact a health-care provider immediately if they experience agitation, depressed mood, and any changes in behavior that are not typical of nicotine withdrawal, or if they experience suicidal thoughts or behavior.
VARENICLINE USE in PATIENTS with CVD: EFFICACY & SAFETY
Study of 714 patients with stable, documented CVD (other than hypertension alone) diagnosed for > 2 months 51% angina, 49% MI, 49% coronary
revascularization Randomized to 12 weeks varenicline or
placebo Monitored over 52 weeks Multisite trial funded by Pfizer, Inc.

Changing Behavior:How You Can Help
HANDOUT
TOBACCO CESSATION REQUIRES BEHAVIOR CHANGE
Fewer than 5% of people who quit without assistance are successful in quitting for more than a year
Many patients underestimate the impact that counseling can have on their ability to quit
Few patients adequately PREPARE and PLAN for their quit attempt
Many patients assume they can just “make themselves quit” when they are ready to do soBehavioral counseling is a key component of treatment
for tobacco use and dependence.

“We ask all of our patients about tobacco use and secondhand smoke exposure, because it is so important for good cardiovascular health.”
ASK
STEP 1: ASK
tobacco users to quit “Quitting tobacco is a critical component of your
care.”
“Quitting smoking is the best thing you can for your heart.”
“Patients who continue to smoke after a heart attack have lower survival than patients who quit smoking.”
“It will be important for your family and close friends to either quit with you or be supportive of your quitting.”
“Creating a smoke-free environment at home is critical to your heart health and success with quitting smoking.”

• Greater quit rates: • > 6 interactions: OR = 1.67• Greater duration & intensity: OR = 3.17• Concurrent use of NRT or bupropion: OR =
2.13Behavioral smoking cessation interventions initiated during hospitalization result in a significantly higher
quit rate compared to usual smoking cessation advice. Aziz et al. (2009). Int J Cardiology.
TOBACCO CESSATION TREATMENT in PATIENTS with CHD
• Meta-analysis: 16 RCTs (N = 2,677), 1974–2003
• Positive treatment effect at 6–12 mos: OR = 1.66• Brief interventions: OR = 0.92 (not significant)• Telephone support: OR = 1.58• Self-help: OR = 1.48• Behavioral therapies: OR = 1.69• Intense interventions (follow-up after 1 month): OR = 1.98
Behavioral smoking cessation interventions in patients with CHD are effective in promoting abstinence at
1 year, provided they are of sufficient duration.Barth et al. (2008). Cochrane Reviews.

SMOKE-FREE HOMES SUPPORT TOBACCO CESSATION
Prevalence of smoke-free homes has been increasing over time
Review of 16 longitudinal and 7 cross-sectional studies: Smokers with smoke-free home were
significantly more likely to make a quit attempt and be abstinent
THE CARDIOLOGY TEAM’s RESPONSIBILITY
The cardiology team has a professional obligation
to address tobacco use and can have an important role in helping patients with
CVD, and their family members,plan for their quit attempts.
TOBACCO CESSATION is an essential component of CVD TREATMENT
for ALL PATIENTS who use tobacco.
