SLC5A2 and heart failure: For major cardiovascular events (MACE), there is no class effect for SGLT-2 inhibitors, as the 7% reduction of MACE risk observed with dapagliflozin in the DECLARE trial was not significant; on the other hand, a class effect is evident for both heart failure and diabetic kidney disease, as in all four trials so far completed (EMPAREG-OUTCOME, CANVAS, DECLARE, CREDENCE) the risk of hospitalization for heart failure and progression of diabetic kidney disease was significantly reduced by all SGLT-2 inhibitors.
