Respiratory diseases often coincide with cardiac problems. However,
airway obstruction is frequently overlooked in patients with heart
The aim of this study was to evaluate chronic obstructive pulmonary
disease (COPD) and asthma prevalence in patients with coronary artery
We performed a cross-sectional, cohort study of 206 patients with
angiographically confirmed coronary artery disease (>50%
narrowing of coronary artery lumen) receiving optimal and regular
cardiac care. The patients were evaluated for COPD and asthma by means
of a structured questionnaire, basic physical examination, allergy skin
tests and spirometry. All procedures were performed at the study site
by the medical staff experienced in allergy and respiratory diseases
diagnosis and management. Written informed consent was provided by each
study participant prior to the study procedures implementation.
In the study group COPD was found in 33 (16%) and asthma in 20 persons
(10%). In the majority of cases respiratory disorder was newly
diagnosed (19/33 for COPD and 9/20 for asthma). In the COPD cases the
degree of airflow limitation according to GOLD classification was most
often moderate (18/33) and mild (11/33), and seldom severe (4/33).
Despite their high prevalence, COPD and asthma in patients with
coronary artery disease are often underdiagnosed and the patients do
not receive complex medical care. Altogether, up to 26% of cardiac
patients could benefit from adequate respiratory management. Screening
for obstructive respiratory disorders should become a standard of care
in this population.
