BACKGROUND: Chronic obstructive pulmonary disease often coexists with cardiovascular diseases and airflow limitation has been known as a risk of cardiovascular death. However, the association between airflow limitation and the history of acute coronary syndrome (ACS) in patients with coronary stenosis remains to be determined.
METHODS: Study subjects were 271 consecutive patients (age: 70.6±9.5 years, sex: 200 males) who underwent coronary angiography and in whom organic coronary stenosis was detected. We collected spirometric data from those patients and investigated the association of the pulmonary function and the history of ACS. We also compared the prevalence of airflow limitation of the present subjects with Japanese epidemiological data that had been previously published.
RESULTS: Multivariate analysis with multiple logistic regression analysis showed that the reduced forced expiratory volume in one second (FEV1.0) less than 80% of predicted value was significantly associated with a history of ACS (odds ratio: 2.81, 95% CI: 1.27-6.20, p<0.02) independently of age, sex, body mass index, and classic coronary risk factors including smoking habit, diabetes mellitus, hypertension, and dyslipidemia. Furthermore, the airflow limitation was more prevalent in the present subjects than in the Japanese general population (25.8% vs. 10.9%, p<0.05).
CONCLUSIONS: Reduced FEV1.0 is associated with a history of ACS in patients with coronary arterial stenosis irrespective of any coronary risk factors. Airflow limitation is more prevalent in patients with coronary stenosis than in the general population.
