The utility and prognostic value of dipyridamole technetium-99m sestamibi myocardial perfusion imaging SPECT in predicting perioperative cardiac events following non-cardiac surgery

Abstract

The incidence of perioperative cardiac events is higher in patients with abnormal MPI. Dipyridamole 99m Tc-MIBI myocardial perfusion imaging can accurately detect the preoperative cardiac risk of patients undergoing major non-cardiac surgery. Based on these findings, the occurrence of perioperative cardiac events in patients with abnormal MPI should be considered, especially in the older age population (age ≥70).

Comparison of stress dobutamine echocardiography and stress dobutamine gated myocardial SPECT for the detection of viable myocardium

“…This finding is consistent with the previous report showing good agreement between DS SPECT and DSE in the recognition of inotropic reserve in infarcted areas [13]. Panza et al [4] mentioned 68% agreement between DSE and thallium scan and Bax et al [1] found 72% agreement between DSE and technetium scan. However, the prior studies did not analyze these results with other methods of viability, such as PET measurements of viability or functional recovery.…”

“…Similar results were reported by Panza et al [4] who tested 201thallium imaging with dobutamine echocardiography, and demonstrated that a large number of segments with 201 thallium uptake may lack contractile reserve. The difference may arise from the mechanisms of the detection of myocardial viability by the two modalities; the cellular processes dependable for a positive inotropic response to adrenergic stimulation require a higher degree of myocyte functional integrity than those responsible for thallium uptake [4].…”

“…Gated myocardial SPECT is recommended for simultaneous assessment of perfusion and function, and permits objective assessment of regional function [1,4]. Although, there are some studies showing that dobutamine gated myocardial SPECT agreed www.nmr.viamedica.pl…”
