- W2359693610 abstract "Objective: To evaluate the prognostic value of left ventricular cavity - to - myocardium count ratio(C/M ratio) on 99m Tc - MIBI myocardial perfusion imaging for patients with myocardial infarction (MI) in the resting state. Methods: Seventy-four pa- tients with MI who underwent 99m To -MIBI myocardial perfusion tomography in the resting state were divided into decreased C/M ra- tio group and normal C/M ratio group. They were followed up for 23 months(range 4-36 months) and even longer than 12 months for patients with no cardiac events(CE). Death due to primary cardiac cause, or nonfatal myocardial reinfarction and CABG or PTCA oc- curring3 months after resting state myocardial perfusion imaging were considered CE. Results: Of the 74 MI patients, forty-one pa- tients had decreased C/M ratio and 33 had normal C/M ratio. During the folow - up period, there were 23 CE in 41 decreased C/M ratio patients and five in 33 normal C/M ratio patients. There were significance difference between decreased C/M ratio patients and normal C/M ratio patients group (X2 = 7. 06, P0 01). Patients with decreased C/M ratio had a significantly lower no - CE rates than those with normal C/M ratio patients(X2 = 4. 14, P0. 05, Log- rank test). With multivariate Cox regression analysis, decreased C/ M ratio was an independent predictor Of CE(RR = 5. 38, 95% confidence interval[CI] 1. 86 - 16. 13, P0. 01 ). Conclusion: In pa- tients with MI, C/M ratio on resting state myocardial perfusion imaging gives useful information in the evaluation of prognosis, de- creased C/M ratio is an important independent predictor of a bad prognosis." @default.
