THE ASSOCIATION BETWEEN SOME SUBCLINICAL CHARACTERISTICS AND PET/CT IMAGING IN PATIENTS WITH POST MYOCARDIAL INFARCTION
Main Article Content
Abstract
Objectives: To investigate some subclinicals characteristics and its association with PET/CT imaging in patients with post myocardial infarction. Subjects and methods: This cross-sectional study included 45 patients with post myocardial infarction who were treated in Cardiology Institute, 108 military hospital from 2011 to 2015. Clinical, subclinical findings were collected and myocardial perfusion SPECT was undergone. 18F-FDG cardiac PET/CT was evaluated to assess myocardial viability and coronary angiography was done for patients who had indication. Results: No differences was found in each parameters of EFsp (ejection fraction), end diastolic volume (EDV), end systolic volume (ESV) among 3 groups (scar group, hibernating group and mixed (hibernating and scar) group). No different was seen in the presence of myocardial hibernating and myocardial scar between patients with chronic total occlusion coronary artery (CTO) suplied with collateral flow and those without collateral flow (p>0,05). Conclusion: In the assessment of myocardial viability, the severity and characteristics of lesions on coronary angiography did not reflect the presence of myocardial viability assessed by 18F-FDG PET/CT. The degree of left ventricular dysfunction on echocardiography were not associated with the presence of myocardium viablility assessed by 18F-FDG PET/CT.
