Prevalence of Perfusion Defects Detected by Stress (99m)Technetium Sestamibi Myocardial Perfusion Single-photon Emission Computed Tomography in Asymptomatic Patients with Breast Cancer
Abstract
Aim: The aim of the present study was to investigate myocardial perfusion in relation to disease history and laboratory parameters of atherosclerosis risk in asymptomatic patients with breast carcinoma. Patients and Methods: One-hundred and eighty-one patients with breast carcinoma were studied.
Myocardial perfusion was assessed using single-photon emission computed tomography (SPECT) with (99m)technetium sestamibi. Results: Perfusion defects were detected in 12 patients (7%).
Higher body-mass index, increased concentrations of D-dimers, C-reactive protein, fibrinogen, glucose, triglycerides, and urinary albumin, a history of hypertension and of radiotherapy to the left chest wall were all associated with increased risk of perfusion defects. In a multivariate stepwise selection logistic regression model, body mass index, albuminuria and radiotherapy to the left hemithorax were significantly associated with the presence of perfusion defects.
Conclusion: In addition to other factors, treatment history may be associated with the presence of perfusion defects in patients with breast cancer.
