Prevalence of microspirometry-defined chronic obstructive pulmonary disease in two European cohorts of patients with significant smoking history hospitalised for acute myocardial infarction

This study evaluated the prevalence of COPD in two cohorts of patients with a smoking history of ≥10 pack‑years who had been hospitalized for acute myocardial infarction. A preliminary diagnosis of clinically significant COPD (defined as an FEV1/FEV6 ratio <0.7 with an FEV1 of <80%) was made using the Vitalograph COPD-6 device.
