Total Ischemic Time

Total ischemic time and outcomes for patients with ST-elevation myocardial infarction: does time of admission make a difference?

OBJECTIVE To investigate whether admission time was associated with the delay of reperfusion therapy and in-hospital death in patients with ST-elevation myocardial infarction (STEMI). METHODS All patients with STEMI who were admitted to the emergency department and underwent primary percutaneous coronary intervention at Peking University People's Hospital between April 2012 and March 2015 wer...

Public transport fleet scheduling for minimizing total transfer waiting time

Public transportation has been one of the most important research fields in the two last decades. The purpose of this paper is to create a schedule for public transport fleets such as buses and metro trains with the goal of minimizing the total transfer waiting time. We extend previous research works in the field of transit schedule with considering headways of each route as decision variables....

The Effect of Reperfusion after Short Time Ischemic on Spinal Cord on Rat

Introduction: Ischemia plays an important role in the development of pathologic in various neuropathies, and reperfusion improves the pathological and physiological abnormalities of ischemic nerves. In this study, the effect of shortreperfusion time after short time ischemic on spinal cord of rat was investigated. Methods: Eighteen rats (Sprague-Dawley, 250-350 g), were divided into 3 groups: g...

[Therapeutic time window in ischemic stroke].

近年,脳梗塞の治療では心筋梗塞の治療と同様に早 期診断・早期治療の重要性が叫ばれ,心筋梗塞が “Heart Attack”と呼ばれ可急的速やかに治療され一命 をとりとめるように,脳梗塞も“Brain Attack”と捉え 同様に速やかに治療を行い,後遺症を最小限にくいと めることの重要性が認識されつつある.脳虚血が発症 して脳血流が遮断されると脳組織は数時間で不可逆性 の変化をきたし壊死に陥って梗塞となる.ひとたび脳 梗塞に罹患すると片麻痺や言語障害などの神経症候, 記憶・記銘力の低下や情緒障害などの精神症状,さら にQOLの低下や痴呆症などの後遺症に苦しむことに なり社会的生命を失うことにもなる. 近年CT(computed tomography),MRI・A(magnetic resonance imaging・angiography),SPECT(single photon e...
