[Hypertension and Framingham general vascular risk score in retinal vein occlusion]

Abstract

Objectives: To determine the prevalence of arterial hypertension (AHT), systolic blood pressure (SBP), the diastolic blood pressure (DPB), and the Framingham vascular risk score (FRS), in subjects with retinal vein occlusion (RVO), as well as in a control group.

Patients and method: A prospective, cross-sectional case and control study was conducted on all patients with a diagnosis of RVO referred to the General Medicine Clinic, and comparing them with a control group. An analysis was performed on the clinical and laboratory variables.

Results: A total of 253 patients with RVO were studied (132 males and 121 females) and 244 controls (112 males and 132 females) of similar age (67.9±12.3 vs. 68.1±9.2 años). The prevalence of AHT, and the SBP and DPB values in the clinic after the RVO were significantly higher in patients with RVO than in the controls (71.5% vs. 51.2%), SBP mmHg (148±22 vs. 138±18mmHg), DBP mmHg (83±10 vs. 77±10mmHg). The de novo diagnosis of AHT was made from the RVO in 23.8% of the cases. Significant differences were found in the FRS between the patients with RVO and the controls (11±8.3 vs. 8.25±6.3. There were no differences in any of the parameters studied between patients with peripheral or central RVO.

Conclusions: Hypertension is very prevalent as significantly more common in patients with RVO than in controls. Its diagnosis and treatment is often established from the RVO. The FRS is greater in patients with RVO. There were no differences in any of the parameters studied between patients with peripheral or central RVO. It is suggested that RVO should be considered a vascular event when defining therapeutic objectives.
