| 内容記述 | Background: We investigated the effect of a permanent pacemaker implantation on myocardial perfusion, because abnormal accumulation on a myocardial perfusion imaging is observed in patients implanted with PPM. Methods and Results: The subjects were 56 patients treated by permanent pacemaker (PPM) implantation for bradyarrhythmia. Resting myocardial perfusion images were acquired at 1 hour after intravenous injection of 99mTc-SESTAMIBI (MIBI) and at 6 hours thereafter. Abnormal accumulation was observed in 11 patients on MIBI early SPECT, and 23 patients on MIBI delayed SPECT. The MIBI delayed SPECT severity score correlated significantly with the paced QRS interval with r = 0.546 (p<0.05), and LVEF with r = -0.673 (p<0.01). In 15 patients who displayed abnormalities on MIBI delayed SPECT, diastolic deceleration time (DDT), regarded as an indicator of microcirculation disorder, was measured with a flow wire. There was a significant correlation between DDT and severity score of the MIBI delayed SPECT with r = -0.874 (P<0.001). Also, DDT correlated significantly with the paced QRS interval and LVEF, respectively, with r = -0.572(P<0.05) andｒ= 0.54(P<0.05). Conclusions: Prolonged persistence of a wide QRS complex tends to reduce myocardial perfusion and cardiac function, and cannot deny possibility of the myocardial microcirculation disorder for the cause. |
