BACKGROUND: A particularly high rate of smoking among South Korean men corresponds to high
rates of cardiovascular disease.
OBJECTIVES: This study evaluated South Korean men hospitalized with cardiovascular disease to
explore beliefs about the health benefits of smoking cessation, to determine smoking cessation inten-
tions, and to identify factors associated with confidence in quitting smoking.
METHODS: This was a cross-sectional, descriptive study.
RESULTS: Of the study’s 97 participants, only 78% believed that smoking cessation avoids or decreases
the chance of developing heart disease; 93% reported their intention to quit; 74% had moderate to high
confidence about quitting within the month after hospital discharge; and 88% preferred to quit by
themselves without help. Significant predictors of low confidence in quitting were being married (odds
ratio: 5.54, 95% confidence interval: 1.33–23.08); being alcohol dependent (odds ratio: 3.25, confidence
interval: 1.20 – 8.80); and starting to smoke at or before 20 years of age (odds ratio: 2.96, confidence
interval: 1.14 –7.68).
CONCLUSION: The study’s participants were motivated to quit smoking for their health, but they must
be educated to understand that smoking is addictive and that special intervention is needed. (Heart
Lung® 2007;36:339 –347.)

outh Korean men have the highest rate of
smoking in the world (57%).

Cardiovascular
disease (CVD) was the second most common
cause of death among South Korean men in 2002.

Despite the risks associated with high rates of
smoking and the evidence of a high prevalence of
CVD among South Korean men, researchers have
rarely investigated smoking cessation in this popu-
lation.
Published studies reporting the benefits of smok-
ing cessation among smokers who had CVD began
to appear in the 1970s.

Although their outcome
measures differed, all of the studies concluded that
there was a substantial benefit from smoking ces-
sation in terms of mortality, survival rate, and re-
current rate of CVD.
8 –11
Through these studies, re-
searchers concluded that smoking cessation is
probably the single most important intervention in
the management of CVD. More recent data reinforce
the findings of previous research. Current studies
show that smoking cessation in patients with CVD
reduced the rate of recurrent CVD events by 40%,
after 1-year follow-up,
12
and the mortality rate due to
recurrent CVD events by 17%, after 20-year follow-up.
