          Cardiovascular protection


          Long-term safety data for DPP-4 inhibitors are not yet available. How-
          ever, there is evidence to suggest these agents may confer some de-
          gree of cardiovascular protection. 63 64  Further data to support or refute
          this hypothesis is currently being collected in large, prospective studies.
                                                                            63
          A number of meta-analyses have recently been published that inves-
          tigate, in detail, the cardiovascular safety of OADs. Sitagliptin was not
          associated  with  an  increased  risk  of  major  adverse  cardiovascular
          events.  Likewise, vildagliptin was not associated with an increased risk
                65
          of  adjudicated  cardiovascular  and  cerebrovascular  events,  even  in
          a patient population that included subjects at increased risk of these
          events. 66
