OBJECTIVES: Myocardial perfusion imaging (MPI) with positron emission tomography (PET) has advantages over single-photon emission computerized tomography, particularly for @entity1 . This investigation was undertaken to define the prognosis of a normal stress PET MPI study in @entity1 . METHODS: The cohort comprised 457 @entity1 evaluated for suspected @entity453 ( @entity453 ) who had normal pharmacologic stress (82)Rb PET MPI. No @entity1 had clinically evident @entity453 . Kaplan-Meier estimates were used to determine @entity204 and initial nonfatal cardiac event rates over 7 years. Log rank tests were used to assess the relationship between baseline cardiac risk and events during follow-up, and to contrast survival in the cohort with age- and gender-matched US census comparators. RESULTS: During follow-up, there were 11 deaths (all nonischemic), 3 nonfatal @entity583 , 3 percutaneous coronary interventions and 1 coronary artery bypass operation. Average risks of @entity204 and initial nonfatal @entity299 were 0.72 and 0.47% per year, respectively. @entity299 were associated with a history of @entity6 (p < 0.0003) and a family history of @entity453 (p < 0.05). CONCLUSION: A normal cardiac PET study is associated with a very low rate of future @entity299 . @entity1 with @entity6 and a strong family history of @entity453 are more likely to sustain events and require close surveillance for the development of @entity301 .
