Diabetic retinopathy grade as a predictive marker of severity of cardiovascular disease and mortality: DIVERSE Study Group

Patients with diabetic retinopathy (DR) are more likely to have subclinical cardiovascular disease. Objective of this study was to assess the prevalence and association of DR grades along with comorbidities in patients with established cardiovascular disease (CVD); association of DR grades beyond ocular morbidity, i.e., long-term outcomes among established CVD; influence of DR grades on prognosis in patients undergoing coronary revascularization. This was a single center, retrospective, data analysis of T2DM patients with established CVD. Goodness of fit was analyzed using Pearson’s chi-square test. DR was observed in 64% (n = 2560) of patients (non-proliferative diabetic retinopathy [NPDR] 37%; proliferative diabetic retinopathy [PDR] 27%). DR and CVD were strongly associated; highest association was observed for congestive heart failure (CHF) (n = 1325), followed by myocardial infarction (MI) (n = 795), unstable angina (UA) (n = 275), and cardiomyopathy (n = 165) (p
