____________________________________________________________ Smoking Statement Issued in 1956 by American Heart Association ___________________________________________________________ • “It is the belief of the committee that much greater knowledge is needed before any conclusions can be drawn concerning relationships between smoking and death rates from coronary heart disease. The acquisition of such knowledge may well require the use of techniques and research methods that have not hitherto been applied to this problem.” • Circulation 1960; vol. 23 ___________________________________________________________
Smoking: Mortality 33.5% of smoking-related deaths among Americans are cardiovascular-related Male smokers die an average of 13.2 years earlier than male nonsmokers Female smokers die an average of 14.5 years earlier than female nonsmokers Current cigarette smoking is a powerful independent predictor of sudden cardiac death in patients with CHD Cigarette smoking results in a two- to threefold risk of dying from CHD Arch Intern Med. 2003;163:2301–2305.

TOBACCO USE AS A CARDIOVASCULAR RISK FACTOR • OVERVIEW OF SMOKING CESSATION AND THE IMPORTANCE OF INTERVENING IN CLINICAL PRACTICE • LESSONS LEARNED FROM THE IMPLEMENTATION AND DISSEMINATION OF A SUCCESSFUL RESEARCH PROGRAM IN HOSPITALIZED PATIENTS • INTRODUCING SYSTEM - WIDE CHANGES FOR SUCCESS WITH CARDIAC AND OTHER HOSPITALIZED PATIENTS
SMOKING: THE FACTS FIFTY MILLION AMERICANS SMOKE (1 IN 4 ADULTS) FIFTY PERCENT ATTEMPT TO QUIT ANNUALLY ONLY 42% OF M.I. SMOKERS RECEIVED SMOKING CESSATION INTERVENTIONS AT HOSPITAL DISCHARGE (NRMI II) ONLY 21% OF SMOKERS RECEIVED COUNSELING @ CLINIC VISITS (1995) TREATMENT IS MOST OFTEN OFFERED TO THOSE WITH TOBACCO-RELATED DISEASES DIRECT/INDIRECT MEDICAL COSTS APPROACH $130 BILLION ANNUALLY
U.S. Deaths Attributable to Cigarette Smoking, 1994, Centers for Disease Control and Prevention
CIGARETTE SMOKING MORTALITY • ONE IN EVERY FIVE DEATHS FROM CARDIOVASCULAR DISEASE IN THE UNITED STATES IS SMOKING-RELATED • ON AVERAGE, SMOKERS DIE SEVEN YEARS EARLIER THAN NONSMOKERS. • 430,700 DEATHS OCCUR ANNUALLY FROM CIGARETTE SMOKING WITH 75% BEING DUE TO CANCERS AND HEART DISEASE. • DEATHS FROM LUNG CANCER AMONG WOMEN HAVE INCREASED 400%. IN 1994, 64,300 WOMEN DIED FROM LUNG CANCER AND 44,300 DIED FROM BREAST CANCER. MORBIDITY AND MORTALITY WEEKLY REPORT, 1997 AMERICAN CANCER SOCIETY, ATLANTA GEORGIA, 1996.
Cigarette Smoking as a CHD Risk Factor • In PDAY study of autopsies performed on 1443 men and women aged 15-34 years, smoking was associated with excess of fatty streaks and raised lesions in the abdominal aorta. • Mechanism of injury from cigarette smoking may come from injury to endothelium, and acute effects ma include alterations in clotting, platelet adhesion, and coronary vasoconstriction due to nicotine. • Relative risk of CHD death from MRFIT study 2.1 for 1-25 cigarettes/day rising to 2.9 for >25 cigarettes/day • Acute MI and sudden death strongly associated with cigarette smoking. • Cigarette smoking has additive effect to CHD risk above lipids, obesity, diabetes, and hypertension
Environmental Tobacco Smoke and CHD • 35,000-40,000 deaths annually from acute MI are associated with environmental tobacco exposure, significantly more than due to lung cancer. • Recent meta analysis of passive smoking incorporating home-based and workplace studies (1699 cases) showed relative risk of 1.49 (1.29-1.72) • Sidestream smoke released into the environment may be more toxic and nonsmokers who are exposed regularly develop various physiologic changes and are more sensitive than regular smokers. • Lower HDL-C and platelet abnormalities, higher CO levels and lower exercise tolerance are noted.
Trends in Cigarette Smoking: High School Youth (Everett et al)
Percent of High School Students Who Reported Cigarette Smoking, 1995, CDC
Prevention and Intervention Strategies in Youth • School-based prevention programs • Social environment / influences • Community-based prevention programs • May enhance effects of school-based programs • State and federal prevention initiatives • Anti-tobacco media campaigns • Restrictions on tobacco advertising • Restrictions on tobacco availability to minors • Restrictions on smoking in public places including schools • Increased taxation
Adult Cessation Strategies • Contingency contracting (wards for abstinence) • Social support (from clinician, group, family, friends) • Relaxation techniques (progressive relaxation, deep breathing) • Stimulus control and cue extinction (restricting where smoking takes place) • Coping skills • Reduced smoking and nicotine fading (gradual reduction) • Multicomponent treatment programs • Hypnosis • Acupuncture • Self-help (written materials, videos, tapes, hotlines, helplines) • Computer-tailored messages
Time-to-Benefit of Smoking Cessation After Last Cigarette Within 20 minutes:BP decreases; body temperature, pulse rate returns to normal Within 24 hours:Risk of MI decreases Within 1 year:Excess risk for CHD is half that of a person who smokes At 5 years:Stroke risk is reduced to that of someone who has never smoked Within 15 years:CHD risk is the same as a person who has never smoked American Lung Association. www.lungusa.org/tobacco/quit_ben.html
Counseling: 5 A’s • Ask: Systematically identify all tobacco-users at every visit • Advise: Strongly urge all smokers to quit • Attempt: Identify smokers willing to try and quit • Assist: Aid the patient in quitting • Arrange: Schedule follow-up contact

Nicotine Replacement Therapy • Potent psychoactive drug that induces euphoria • Effects are related to blood concentration and the rate of increase in concentration • Safe in patients with cardiovascular disease • Should be used as part of smoking cessation therapy; however, many individuals may quit without it
Smoking and Nicotine • Other toxins in tobacco smoke, not nicotine, are responsible for majority of adverse health effects >4000 different chemicals Tar, carbon monoxide, irritants, and oxidant gases >40 carcinogens • The main adverse effect of nicotine from tobacco is addiction, which sustains tobacco use • Nicotine dependence leads to continued exposure to toxins in tobacco smoke Smith et al.

Nicotine Replacement Therapy (NRT) Goal: Attenuate symptoms related to nicotine withdrawal • Dysphoric or depressed mood • Insomnia • Irritability, frustration, or anger • Anxiety • Difficulty concentrating • Restlessness • Decreased heart rate • Increased appetite or weight gain
NRT: Treatment Options • Forms of NRT: Gum, Patch, Inhaler, Lozenge, Nasal spray, Sublingual tablet • All forms of NRT appear to be similarly effective • NRT choice may be based on susceptibility to side effects, patient preference, and availability • Little research on combinations of different types of NRT • Limited evidence that adding another form of NRT to the nicotine patch increases the success rate

Safety of NRT • NRT is safe in most individuals with cardiovascular disease, even with concomitant smoking • There is a negligible risk of cancer compared to the risk from continued smoking • Although it is a potential fetal teratogen, the benefits outweigh the risks of smoking during pregnancy • There is a low risk of abuse
Buproprion (Zyban) • Sustained release form of the antidepressant • Acts by enhancing CNS noradrenergic and dopaminergic function • Start 1 week before smoking cessation date • 150 mg QD x 3d, then 150 mg BID x 60d • Higher doses and longer duration with greater side effects and no clear benefit
Buproprion (Zyban) vs. NRT Jorenby DE et al. N Engl J Med. 1999 Mar 4;340(9):685-91
Other Therapies: Limited Success Clonidine Nortryptiline (tricyclic antidepressant) Maclobemide (MAO-inhibitor) Buspirone (anxiolytic) Naloxone (opiate antagonist) Naltrexone (opiate antagonist) Amphetamines
‘Reduced risk’ cigarettes • Includes low tar and ‘light’ cigarettes, and novel products that deliver nicotine with minimal tobacco combustion • Low tar cigarettes have not be shown to substantially reduce health hazards of smoking but do provide sufficient nicotine to sustain addiction • Some novel products may deliver fewer or lower levels of toxins but some deliver more carbon monoxide. • Smoking cessation medications are most likely safer than any ‘reduced risk’ cigarette
Smokeless tobacco • Snuff or chewing tobacco has been suggested as a potential aid to harm reduction or smoking cessation • Such products known to cause oral cancer • Smokeless tobacco is addictive and not recommended for smoking cessation
