Epidemiological studies have indicated that chronic obstructive pulmonary disease (COPD) may be associated with an increased incidence of ischaemic cardiac events. We performed a post-hoc analysis of the EUROSCOP study - a 3-year, placebo-controlled study of an inhaled corticosteroid budesonide 800 µg·day-1 in smokers (mean age 52 years) with mild COPD. We evaluated whether long-term budesonide treatment attenuates the incidence of ischaemic cardiac events, including angina pectoris, myocardial infarction, coronary artery disorder and myocardial ischaemia. Among the 1175 patients evaluated for safety, 49 patients (4.2%) experienced 60 ischaemic cardiac events. Patients treated with budesonide had a significantly lower incidence of ischaemic cardiac events (18 out of 593; 3.0%) than those receiving placebo (31 out of 582; 5.3%; p<0.05). These results support the hypothesis that treatment with inhaled budesonide reduces ischaemic cardiac events in patients with mild COPD. Keywords: Budesonide, COPD, ischaemic cardiac events
