[Two cases of myocardial bridge associated with myocardial ischemia].
と拡張期で内径は顕著には変化しない.しかし,冠動 脈造影の施行例を検討すると,冠動脈が収縮期にのみ 狭窄像を呈し,拡張期には正常化する症例が散見され る.この現象は,通常心外膜側表面を走行すべき冠動 脈が,一部心筋層内を走行し,その結果収縮期に収縮 した心筋により圧迫され,冠動脈造影上狭窄像を呈す ることになる.この所見は機能的変化によるもので, 冠動脈の動脈硬化性病変とは明らかに異なり,臨床的 にも区別して取り扱うことが必要である.このような 現象が心筋ブリッジ(myocardial bridge,または myocardial squeezing)と呼ばれるもので,心筋虚血および 動脈硬化症との関連性が注目されている.以下に myocardial bridge と心筋虚血との関係を示唆する 2 症例 を紹介する. 症例 1:72 歳,女性.発作性心房細動および狭心症 にて外来通院中...
متن کاملMyocardial Stunning in Dogs
This study was undertaken to elucidate whether cal-adrenoceptor activity is beneficial to contractile dysfunction during reperfusion after a brief period of ischemia (stunned myocardium) in 54 open-chest dogs. Contractile dysfunction assessed by fractional shortening (FS) was observed 3 hours after the onset of reperfusion following 15 minutes of complete occlusion of the left anterior descendi...
متن کاملMechanism of myocardial "stunning".
Among the numerous mechanisms proposed for myocardial stunning, three appear to be more plausible: 1) generation of oxygen radicals, 2) calcium overload, and 3) excitation-contraction uncoupling. First, the evidence for a pathogenetic role of oxygen-derived free radicals in myocardial stunning is overwhelming. In the setting of a single 15-minute coronary occlusion, mitigation of stunning by an...
متن کاملMyocardial Noncompaction Presenting With Myocardial Bridge
Myocardial noncompaction, namly isolated noncompaction of the left ventricular myocardium (NVM), is a rare congenital disease. It can be either seen in the absence of other cardiac anomalies, or associated with other congenital cardiac defects, mostly stenotic lesions of the left ventricular outflow tract. A myocardial bridge (MB) is thought being associated with coronary heart disease, such as...
متن کاملMultiple myocardial bridge in a 59 year-old woman
Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...
