Serum level of low-density lipoprotein cholesterol in hypertensive retinopathy

Increased serum level of low-density lipoprotein is associated with coronary artery disease. There are, however, no reports on whether the same is true in hypertensive retinopathy. A cross-sectional comparative study was carried out to evaluate the serum level status of low-density lipoprotein in hypertensive retinopathy, including 30 randomly selected subjects with hypertensive retinopathy; age and gender matched 26 hypertensives without fundus changes. Serum low-density lipoprotein cholesterol (LDL-C) levels were assessed in all subjects. Results showed statistically significant (p < 0.0196) higher serum levels of LDL-C in hypertensive patients with retinopathy (mean +/- SD = 2.45 +/- 1.76 mmol/l, SE = 0.33 and 95% CI = 1.79-3.11 vs mean +/- SD = 1.6 +/- 0.4 mmol/l, SE = 0.08 and 95% CI = 1.44-1.76). An increased serum level of LDL-C is associated with hypertensive retinopathy.
