Medical Research: What is the background for this study? What are the main findings?

Dr. Saremi: Our study was a post-hoc analysis of the data that was available from VA cooperative study,  the Veterans Affair Diabetes Trial  (VADT).  The VADT was one of the  recent landmark studies examining the effect of intensive glycemic control on cardiovascular events  in older adults with type 2 diabetes.

The main finding in the VADT and other two other landmark studies (ACCORD and ADVANCE ) was that intensive glycemic control does not reduce cardiovascular  disease events in people with type 2 diabetes of moderate to long duration.  However, our subsequent post-hoc analysis suggests that intensive glycemic control was associated with reduced risk of cardiovascular events in Hispanics, but not in non-Hispanic Whites or Blacks.

Medical Research: What should clinicians and patients take away from your report?

Dr. Saremi: Well, as we now know, tight glycemic control is not for everyone. Our study points out that  the risk-benefit ratio for intensive diabetes treatment should be evaluated in different race/ethnic populations. An important take away from our study was that while receiving similar access to healthcare and diabetes guidance, Hispanics not only respond well to glucose lowering efforts, but may also gain additional benefit with respect to its consequences on cardiovascular disease events.

Medical Research: What recommendations do you have for future research as a result of this study?

Dr. Saremi: The VADT was not designed to investigate the effect of  intensive glycemic control in race/ethnic subgroups, as a result  the sample size for this post-hoc analysis of race/ethnicity groups was relatively small. More research is needed and our results needs to be confirmed in other well powered studies in different populations.

Also, further work will be needed to clarify the potential mechanisms accounting for the apparent “enhanced cardiovascular response” to glucose lowering therapy in Hispanics.
