Description
Objective: Assess the impact of coronary events in smoking cessation habits, and study the association between smoking habits and coronary artery disease.
Methods: With a clinical structured interview, three groups were selected (n=68), from the patients of the Cardiology Service of Hospital Militar Principal.
Sample 1 was composed by patients with stable, and unstable angina (n= 18), sample 2 by patients with myocardial infarction (n=26), and sample 3 by individuals with other cardiac disease (arterial
hypertension, or valve disease) (n=24). The
individuals were aged between 48 and 75. The
following statistical procedures were used:
correspondence analysis, chi-square test (x2 ~ and Fisher exact test.
Results: The association between smoking habits(non smoker, former smoker, and current smoker),and type of disease (angina, myocardial infarction, and arterial hypertension), was statistically
significant [X2(68)=l4,5; p=O,OO6], and there was also a significant association between smoking habits and coronary artery disease [~2(68)=4,O;p=O,O45]. The category of ex-smokers and myocardial patients also showed significant association (Fisher exact test=O,036). Conclusions: Previous myocardial infarction events constitute an experience of severe suffering and
crisis, in which the patient accepts to stop smoking. We also confirm that smoking is a risk factor for myocardial infarction. Thus the objective of clinic objectivo de promover e reforçar a intenção de abandonar o consumo de tabaco revela-se de extrema importância e utilidade nesta tomada de
decisão.
