Relation between pharmacological stress ECG, 13NH3-PET/CT outcome and the occurrence of cardiac events during follow-up in women with chest pain

Aim Evaluation of major adverse cardiovascular events (MACE) in women referred for 13NH3-PET/CT in relation to scan outcome and pharmacological stress ECG (PxECG) results. Patients and methods Six hundred twenty-four women, referred for 13NH3-PET/CT between 2012 and 2016, were included. Demographic data and MACE during follow-up (407 ± 207 days) were retrieved from electronic patient charts. 13NH3-PET/CT was scored as either normal or abnormal. PxECG was scored as negative, non-diagnostic or positive. PxECG was compared with 13NH3-PET/CT and related to MACE. Results The 13NH3-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%). 13NH3-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 13NH3-PET/CT versus three with normal 13NH3-PET/CT (P
