Imaging raises heart disease alarm in COPD
Using cardiac imaging, researchers have found that patients with chronic obstructive pulmonary disease (COPD) have significantly impaired myocardial perfusion reserve (MPR) - a powerful indicator of cardiac risk.
"Altered MPR indicates an early alteration in myocardial tissue and vascular properties in these subjects with COPD," comment authors Katsuya Onishi (Mie University Graduate School of Medicine, Japan) and colleagues, who say the findings could help clinicians to detect atherosclerosis sooner in COPD patients.
The study involved 20 patients with mild-moderate COPD, 20 age-matched smoking controls, and 20 age-matched non-smoking controls. All participants had normal cardiac imaging results, indicating no regional myocardial ischemia or infarction. Read more.
