Hyperhomocysteinaemia and poor vitamin B status in chronic obstructive pulmonary disease

Patients with chronic obstructive pulmonary disease (COPD) are at increased atherothrombotic risk. Preliminary findings have suggested that COPD patients may have increased plasma total homocysteine (tHcy), a cardiovascular risk factor often caused by a poor B vitamin status, but plasma levels of such vitamins were not measured.
