Plasma lipoproteins in chronic obstructive pulmonary disease.

Plasma lipoprotein fractions have been assessed in 29 patients with chronic obstructive pulmonary disease (COPD), and compared with non-COPD subjects. Triglycerides were significantly lower in COPD females only, the other parameters being almost identical. Thus, the atherosclerosis index of plasma lipoproteins in COPD did not differ almost at all from that of non-COPD subjects, demonstrating that the low prevalence of angina and/or myocardial infarction in COPD patients is not only a consequence of reduced coronary atherosclerosis.
