Shorter door-to-balloon time, better long-term clinical outcomes in ST-segment elevation myocardial infarction patients: J-MINUET substudy.

Background: The impact of shorter door-to-balloon (DTB time on long-term outcomes in ST-segment elevation myocardial infarction (STEMI treated with primary percutaneous coronary intervention (PPCI has not been fully elucidated.

Methods: We investigated 3283 consecutive patients with acute myocardial infarction selected from a prospective, nationwide, multicenter registry (J-MINUET database comprising 28 institutions in Japan between July 2012 and March 2014. Among the study population, we analyzed 1639 STEMI patients who had PPCI within 12 h of onset.

Long-Term Prognosis of Patients with Myocardial Infarction Type 1 and Type 2 with and without Involvement of Coronary Vasospasm.

While prognoses in relation to myocardial infarction (MI) type have been elucidated in past reports, the results were not consistent, perhaps due to occurrence of Type 2 MI with CVS and its mortality. The Japanese registry of acute Myocardial Infarction diagnosed by Universal Definition (J-MINUET) is a prospective multicenter registry in Japan. In contrast to thromboembolic event-related Type 1 myocardial infarction (MI), clinical features of Type 2 MI, including coronary vasospasm (CVS), are varied due to the heterogeneous nature of its development.

Pre-Procedural Thrombolysis in Myocardial Infarction Flow in Patients with ST-Segment Elevation Myocardial Infarction.

It has been shown that the patency of an infarct-related artery (IRA) before primary percutaneous coronary intervention determines post-procedural success, better preservation of left ventricular function, and lower in-hospital mortality. However, the factors associated with pre-procedural Thrombolysis In Myocardial Infarction (TIMI) flow have not been fully investigated.The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective multicenter registry conducted at 28 Japanese medical institutions between July 2012 and March 2014.

Treatment strategy modification and its implication on the medical cost of fractional flow reserve-guided percutaneous coronary intervention in Japan.

Background: Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) could improve outcome compared with angiography-guided PCI. However, the economic impact of FFR-guided PCI remains largely unknown in the medical system in Japan. We evaluated the impact of treatment strategy modification by FFR measurement on the direct medical cost using a model analysis with a decision tree model in Japan.

A lower eicosapentaenoic acid/arachidonic acid ratio is associated with in-hospital fatal arrhythmic events in patients with acute myocardial infarction: a J-MINUET substudy.

The ratio of serum eicosapentaenoic acid (EPA) to arachidonic acid (AA) is significantly associated with long-term clinical outcomes in patients with acute myocardial infarction (AMI). However, it has not been conclusively demonstrated that higher serum EPA/AA ratio fares better clinical outcomes in the early phase of AMI. The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective multicenter registry conducted in 28 Japanese medical institutions between July 2012 and March 2014.

One-Year Outcome of Fractional Flow Reserve-Based Coronary Intervention in Japanese Daily Practice - CVIT-DEFER Registry.

Background: Clinical use of fractional flow reserve (FFR) has been rapidly increasing, but outcomes after FFR-based coronary intervention in Japanese daily clinical practice have not been well investigated.

Methods and results: The prospective multicenter cardiovascular intervention therapeutics registry (CVIT)-DEFER enrolled consecutive patients for whom FFR measurement was clinically indicated. This study comprised 3,857 vessels in 3,272 patients.
