- W2043781625 abstract "Abstract Objective The objective of this study was to investigate predictor variables at the moment of normal stress-rest myocardial perfusion gated SPECT for the indication of a second gated SPECT. Materials and methods A prospective, single center cohort study was conducted. We evaluated 2326 consecutive patients (age 63.6 ± 13 years, 57.3% females) without perfusion defects and with normal left ventricular ejection fraction on a myocardial perfusion gated SPECT. Clinical and stress test variables were studied to predict indication of a second gated SPECT and presence of reversible perfusion defects in the second gated SPECT. Results During a mean follow-up of 3.6 ± 2 years a second gated SPECT was performed in 286 patients (12.3%). Independent predictor variables of a second gated SPECT were presence of three or more cardiovascular risk factors (χ2: 5.510; HR: 1.4; p = 0.019), previous acute myocardial infarction (χ2: 3.867; HR: 1.4; p = 0.049), previous coronary revascularization (χ2: 41.081; HR: 2.5; p Conclusions In patients with a first normal myocardial perfusion gated SPECT, various clinical factors and variables derived from the stress test affect the indication of a second gated SPECT and the presence of ischemia in the latter." @default.
