However, in patients with retinopathy of vascular etiology (hypertensive, diabetic or atherosclerotic) the benefit of stricter control of lipid in the long term has been little studied. Methods Prospective study of a cohort of 107 patients who underwent fundus and coronary angiography, of which 42 (39.3%) required percutaneous revascularization. During the follow-up, new cardiovascular events and analytical control of cardiovascular risk factors were recorded. Results Mean age was 75.19 ± 11.53 years. 60.7% were men, 78.5% were hypertensive, 32.7% were diabetic, and dyslipidemia was observed in 57%. Initially, 28% had 1-vessel disease, 14% 2-vessel, 8.4% 3-vessel, and 3.8% left common trunk. 0.9% had diabetic retinopathy, 3.7% had hypertensive retinopathy, 1.9% atherosclerotic, 70.1% had a combination of hypertensive and atherosclerotic retinopathy, and 7.5% signs compatible with all types. Initial and final mean values of LDL-c and HDL-c by type of retinopathy are in Table 1. During follow-up, a significant improvement in LDL-c and HDL-c levels was observed in total patients and in patients with hypertensive and atherosclerotic retinopathy, however globally lipid control was poor and only 18.9% of the total of the sample reached the recommended levels for very high-risk people (<55 LDL-C). Advanced hypertensive retinopathy patients with a greater reduction in LDL-C during follow-up, recorded lower mortality (p = 0.004). Besides, patients with previous percutaneous revascularization showed a greater decrease in LDL levels at the end of follow-up (69.5 ± 26.1 vs 103 ± 41.47; p <0.001); without significant changes in the rest of parameters. Conclusions In patients with vascular etiology retinopathy, long-term lipid control is poor. However, patients with hypertensive retinopathy and a greater reduction in LDL-c had lower long-term mortality. Hypertensive retinopathy Initial Final Sig.
