Although the transfer of cholesteryl ester (CE) from high-density lipoprotein (HDL) to the apolipoprotein B-containing lipoproteins (very-low- density lipoproteins + low-density lipoproteins) has been shown to be abnormally increased in a number of conditions associated with increased cardiovascular risk, it has not been studied in patients with essential hypertension (EH). To determine whether subjects with EH have increased CE transport, CE transfer (CET) was estimated isotopically and lipoprotein lipid and phospholipid composition determined in a group of 14 untreated normolipidemic (triglycerides 116 ± 46, cholesterol 185 ± 30, HDL 38 ± 10 mg/dl) otherwise healthy ethnically diverse EH subjects. CET was significantly increased in EH subjects compared to a similar group of normotensive controls (EH: k = 0.27 ± 0.09 vs. control k= 0.11 ± 0.02; P < 0.01). Lipoprotein concentration and composition were comparable in the two groups and closely resembled that of an age- and sex-matched reference group. The abnormal increase in CET persisted (k = 0.25 ± 0.12) after 3 months of treatment with the angiotensin converting enzyme (ACE) inhibitor ramipril without a change in either plasma or lipoprotein lipids. Thus, CET is increased in normolipidemic subjects with EH and is not affected by the ACE inhibitor ramipril.
