Abstract
Objective: To evaluate left ventricular synchrony parameters using gated myocardial perfusion single photon emission computed tomography (GSPECT) in post myocardial infarction (MI) patients. Subject and method: A cross-sectional study was conducted on 34 subjects without cardiovascular disease and 104 post-MI patients. Result: Left ventricular dyssynchrony parameters including PSD and HBW were 48.7 ± 19.49 and 154.95 ± 71.97 in post-MI group compared to 17.5 ± 7.24 and 53.9 ± 15.14 respectively in the control group, respectively (p<0.01). 77% and 81% of post-MI patients had increased PSD and HBW with left ventricular dyssynchrony. PSD and HBW has increased significantly in post-MI patients with NYHA III-V, low EF compared to NYHA I-II patient group without left ventricular dysfunction. Conclusion: Left ventricular dyssynchrony parameters were commonly detected by GSPECT in post-MI patients. PSD and HBW increased significantly in post-MI patients and were related with NYHA and left ventricular dysfunction.
