Two years ago, data presented at the annual American Diabetes Association (ADA) meeting in New Orleans showed a marked decrease in deaths, especially those due to cardiovascular disease, with the use of empagliflozin. Two major questions have been asked: (i) was the result a fluke; and (ii) was it a class effect, or was it specific to the agent used? The hope that both questions would be answered by a second study has been answered: the conclusions of EMPA-REG were not an anomaly and it is a class effect, not one caused by a specific drug. Importantly, do these studies require us to alter our algorithms for the treatment of type 2 diabetes? The CANagliflozin cardioVascular Assessment Study (CANVAS) was designed similarly to EMPA-REG, enrolling individuals who either had known cardiac disease or were at high risk for cardiac disease. ⋯ Values of HbA1c are only a surrogate measure of diabetes. Currently, there is little agreement on the treatment algorithm for diabetes after metformin therapy. One may now argue that an SGLT2 inhibitor should be the preferred second-line therapy.
