  • Current interpretation of myocardial stunning

    2018, Trends in Cardiovascular Medicine
    Citation Excerpt :

    The relationship between autonomic nervous system activity and coronary vasoreactivity during transient myocardial ischemia may promote the occurrence of vasospastic angina [30]. However, despite myocardial stunning occurring in this context, its prevalence is very low as demonstrated by the paucity of existing case reports [31]. It is likely that only recurrent and/or prolonged episodes of Prinzmetal angina cause myocardial stunning.

  • Takotsubo cardiomyopathy - The current state of knowledge

    2010, International Journal of Cardiology
    Citation Excerpt :

    Fujii et al. [22] demonstrated that patients with TTC who had simultaneous multivessel epicardial coronary artery spasm induced by hyperventilation had a higher degree and longer duration of myocardial ischemia than those with single vessel spasm. Fournier et al. [23] reported a case of a patient who had transient LV dysfunction but also demonstrated spontaneous simultaneous three-vessel spasm during coronary angiography. Simultaneous multivessel epicardial coronary artery spasm may contribute to the onset of Takotsubo-like LV dysfunction.

  • Tako-tsubo - like left ventricular dysfunction with ST-segment elevation: A novel cardiac syndrome mimicking acute myocardial infarction

    2002, American Heart Journal
    Citation Excerpt :

    Fujii et al15 previously demonstrated that patients with simultaneous multivessel epicardial coronary spasm induced by hyperventilation had a higher degree and longer duration of myocardial ischemia than those with single vessel spasm. Fournier et al16 reported on a patient with transient left ventricular dysfunction who had spontaneous simultaneous 3-vessel spasm during coronary angiography. They also showed T-wave inversion and QT-interval prolongation as observed in our study, and they believed that vasospasm might extend over a very wide area of the coronary tree and that it might result in severe consequences—regressive but relatively long-lasting—on left ventricular function.

  • Transient left ventricular apical ballooning without coronary artery stenosis: A novel heart syndrome mimicking acute myocardial infarction

    2001, Journal of the American College of Cardiology
    Citation Excerpt :

    Therefore, we could not confirm reversible wall motion abnormality as in apical stunned myocardium and, instead, named this clinical syndrome “transient LV apical ballooning.” Transient wall motion abnormality after multiple vasospastic angina has also been postulated to be a cause of stunned myocardium (2,7–12,17–19). In our series of cases, provocative vasospasm was confirmed only in limited cases (10/48, 21%).
