ABSTRACT
Background: Among the different imaging patterns found in myocardial perfusion imaging, the true significance of the reverse reversibility remains a controversial subject.
Objective: The objective of this study was to evaluate the prevalence of reverse reversibility and its relation to left ventricular systolic function among a cohort of patients who underwent coronary angiography and scintigraphic study.
Material and methods: We retrospectively analyzed the data of patients with normal coronary arteries on angiography and that had a scintigraphic study.
Results: There were 42 patients who had normal coronaries on coronary angiography and had a scintigraphic study; 16 (38.1%) had reverse reversibility pattern. Patients with reverse reversibility pattern showed higher prevalence of myocardial infarction (31 vs. 7.7%) and diabetes mellitus type 2 (50 vs. 23%) than those who did not show the pattern. Subjects with severe reverse reversibility had lower left ventricular ejection fractions (43.3 ± 1.5% vs. 61.5 ± 15.4%) than subjects without it.
Conclusion: Among patients undergoing coronary angiography and Tc99-sestamibi myocardial perfusion scintigraphy, severe reverse reversibility was associated with lower left ventricular ejection fraction.
