Abstract
- Aim: Evaluation of major adverse cardiovascular events (MACE) in women referred for NH3-PET/CT in relation to scan outcome and pharmacological stress ECG (PxECG) results.<br />Patients and Methods: Six hundred twenty-four women, referred for NH3-PET/CT between 2012 and 2016, were included. Demographic data and MACE during follow-up (407 ± 207 days) were retrieved from electronic patient charts. NH3-PET/CT was scored as either normal or abnormal. PxECG was scored as negative, non-diagnostic or positive. PxECG was compared with NH3-PET/CT and related to MACE.<br />Results: The NH3-PET/CT was normal in 482/624 (77%) and abnormal in 142/624 (23%). PxECG was negative in 234/624 (38%), non-diagnostic in 365/624 (58%) and positive in 25/624 (4%). NH3-PET/CT was normal in 87, 71 and 72% with normal, nondiagnostic and positive PxECG, respectively. 41/624(7%) experienced a MACE, 38 with abnormal NH3-PET/CT versus three with normal NH3-PET/CT (P < 0.001). MACE occurred in 5/234 (0.9%), 31/365 (8%) and 5/25 (20%) with normal, non-diagnostic and positive PxECG, respectively (P < 0.001). No MACEs were seen in 204 with both normal PxECG and NH3-PET/CT versus 5/30(17%) with normal PxECG but abnormal NH3-PET/. No MACE occurred in 3/260(1%) with non-diagnostic PxECG and normal NH3-PET/CT versus 28/105(27%) with non-diagnostic PxECG and abnormal NH3-PET/CT. 0/18 with positive PxECG and normal NH3-PET/CT showed MACE versus 5/7(71%) with a positive PxECG and abnormal NH3-PET/CT.<br />Conclusion: Normal NH3-PET/CT is most prevalent in women with normal PxECG. The occurrence of MACE during follow-up is more frequently related to an abnormal NH3-PET/CT than to PxECG. Furthermore, in women with positive PxECG but normal NH3-PET/CT no MACE are to be expected.
