ESC 2017 Japanese EMPATHY study shows less cerebral and possibly cardiac events with more intensive statin treatment in high-risk diabetics with retinopathy.

Japanese study questions benefit of treat-to-target statin therapy in diabetic retinopathy(EMPATHY)

Presented at the ESC congress 2017 by: Hiroshi Itoh (Tokyo, Japan)


There is limited evidence about the optimal treatment regime with statins in patients with diabetes. Prior studies included only a few diabetic patients or were compared with placebo (CARDS). Diabetics with retinopathy have a higher risk on cardiovascular events compared to diabetics without retinopathy.

Therefore, the Japanese EMPATHY trial investigated a treat-to-target protocol with statins including intensive treatment in 5.042 diabetic patients with hypercholesterolemia and retinopathy. Based on different treatment protocols between Japan, Europe and the US, an LDL-c treatment target of <70 mg/dL (ADA/ACC 2008, intensive arm) and 100-120 mg/dL (JAS 2007, standard arm) were chosen. Median follow-up was 37 months.

Main results


Striving to an LDL-c <70 mg/dL in high-risk diabetic patients with hypercholesterolemia and retinopathy seems to result in a clinical benefit for these patients. This needs further investigation.

During the discussion at the press conference, Itoh mentioned that about halve of patients did not reach their LDL-c target in the study. This is a result of the insurance system in Japan, leading to high costs for patients in the intensive treatment arm. Patients in the standard arm were possible not treated long enough. In addition, he stated in a press release that the number of cardiac events were low in the study. There were more cerebral than cardiac events, something that is typical for Asian populations.
