Emotional stress can precipitate severe, reversible left ventricular dysfunction (myocardial stunning) in patients without coronary disease, likely driven by exaggerated sympathetic stimulation.
May support sympathetic inhibition in stress cardiomyopathy; leaves open confirmation in prospective trials.
Emotional stress can precipitate severe, reversible left ventricular dysfunction in patients without coronary disease. Exaggerated sympathetic stimulation is probably central to the cause of this syndrome.
