How do systolic and diastolic mechanics in stress cardiomyopathy compare to acute LAD-territory myocardial infarction and control subjects?
Despite differing pathophysiology, stress cardiomyopathy and acute LAD-territory MI present with indistinguishable and severe systolic and diastolic dysfunction compared to controls.
SCM and LAD MI show severe diastolic dysfunction. At similar left ventricular volumes, their diastolic pressures are more than twice as high as in control subjects, and systolic dysfunction is equally reduced in SCM and LAD MI. Despite a completely different pathophysiology in terms of systolic and diastolic function, SCM is indistinguishable from acute LAD-territory MI.
