AB KEY  POINTSExercise  is  the  preferred  modality  for  stress  testing,  whenever  possible.Pharmacologic  stress  myocardial  perfusion  imaging  (MPI)  has  been  well  validated  when  compared  to  exercise  MPI  in  terms  of  diagnostic  accuracy  and  risk  stratification.Caffeine  or  aminophylline  should  be  used  to  reverse  adverse  effects  associated  with  vasodilator  pharmacologic  stress.Adjunctive  exercise  with  pharmacologic  stress  reduces  side  effects,  enhances  image  quality,  and  improves  the  detection  of  myocardial  ischemia.Regadenoson  is  the  most  commonly  used  vasodilator  in  pharmacologic  stress  testing,  with  outstanding  clinical  value,  ease  of  administration,  and  reduced  side  effects.Beta  blockers  and  other  antianginal  medications  should  usually  be  withheld  prior  to  exercise  and  pharmacologic  stress  testing.  Recent  studies,  however,  have  shown  that  if  not  feasible  to  hold  beta  blockers  prior  to  pharmacologic  MPI,  testing  is  still  possible  with  similar  results.
