[Erythrocyte filterability of angina patients]

Erythrocyte filterability and its relation to erythrocyte volume, hemoglobin level and cholesterol/phospholipid ratio were studied in anginal patients. A 25% decrease in filterability and elevated erythrocyte cholesterol/phospholipid ratios were found in anginal patients, as compared to normal subjects. A close inverse correlation (r = -0.623) was demonstrated between erythrocyte filterability and cholesterol/phospholipid ratio. Mean erythrocyte volume and Hb levels were similar in anginal patients to those of normal subjects.
