Why the study?
Does maximum systolic elastance (Emax) accurately reflect left ventricular contractile dysfunction in the presence of diastolic dysfunction in canine hearts?
Does maximum systolic elastance (Emax) accurately reflect left ventricular contractile dysfunction in the presence of diastolic dysfunction in canine hearts?
Maximum systolic elastance (Emax) may fail to accurately detect declines in left ventricular contractile function when concurrent diastolic dysfunction is present.
No takes yet. Share an insight, caveat, or question.
Emax may fail to detect contractile dysfunction amid diastolic impairment after ischemia; leaves open its reliability as sole contractility index.
Zile et al. (1991) studied this question.
