[Usefulness of stress MPI for assessment of PCI indication--comparison with FFRmyo evaluation using pressure sensor wire].

Purpose: To examine the usefulness of percutaneous coronary intervention (PCI) indication assessment using stress myocardial perfusion imaging (St-MPI).

Background: The usefulness of myocardial fractional flow reserve (FFRmyo) using a pressure sensor wire for the assessment of PCI indication has been reported in recent years. However, we have frequently experienced discrepancies between results from FFRmyo and St-MPI.

[Feasibility of long-term outcome prediction in acute myocardial infarction using the discordance between early and delayed image on 123I-BMIPP myocardial scintigraphy].

Objectives: The feasibility of long-term outcome prediction using BMIPP myocardial scintigraphy was evaluated in cases of acute myocardial infarction.

Methods: BMIPP myocardial scintigraphy was performed on 165 patients with first acute myocardial infarction at the time of discharge from the hospital (average of 27 days after disease on set). Discordance between early and delayed image was checked and its relation to later cardiac events (during the mean follow up period of 64.

[Assessment of therapeutic effect in acute myocardial infarction using early/delayed images of 123I-BMIPP myocardial scintigraphy].

This study was aimed at analyzing the discordance between the initial and late scintigraphic images in patients with acute myocardial infarction (AMI), and utilizing the data obtained for the treatment of AMI patients. Ninety-one patients with a history of the first episode of AMI were enrolled as subjects for this study. Emergency coronary angiography was performed in all the patients and left ventriculography (LVG) was carried out subsequently.
