We intended to check out the worths of EAT determined from CT to anticipate the response to CRT in patients with non-ischemic systolic HF. Methods: Forty-one patients with CRT were back to back recruited for our research study. All patients obtained both gated relaxing Single Photon Emission CT myocardial perfusion imaging and dual-source multi-detector row CT scans. The meaning of CRT response was an enhancement of 5% in left ventricular ejection fraction at 6 months after CRT implantation. Results: After 6 months of follow-up, 58. 5% of patients replied to CRT. In addition, the QRS period and EAT thicknesses of the right AV groove and left AV groove were independent forecasters of CRT response in the multivariate logistic regression analysis. Conclusions: The EAT thickness of the left AV groove in patients with non-ischemic systolic HF is related to the TPD of LV and LV systolic dyssynchrony.
