Card Set Information
what is Hibernating myocardium?
reduced perfusion and contraction resulting in chronic LV dysfunction. this is reverseable with restoration of myocardial perfusion.
what is stunned myocardium?
abnormal contraction despite normal coronary blood flow.
May persist for days/weeks following angioplasty or thrombolytic therapy, making it difficult to assess the therapy
