Key result
Dynamic cardiomyoplasty stimulation increases contractility but fails to augment cardiac output due to reduced end-diastolic volume.
Why the study?
Does dynamic cardiomyoplasty with wrap stimulation improve cardiac function in nonfailing hearts wrapped by conditioned muscle?
Does dynamic cardiomyoplasty with wrap stimulation improve cardiac function in nonfailing hearts wrapped by conditioned muscle?
In nonfailing hearts, dynamic cardiomyoplasty increases contractility but simultaneously decreases end-diastolic volume, preventing augmentation of cardiac output, though these changes may theoretically benefit dilated cardiomyopathy.
No takes yet. Share an insight, caveat, or question.
Does not support use in nonfailing hearts; leaves open potential benefit in dilated cardiomyopathy.
Cho et al. (1993) studied Nonfailing heart. Dynamic cardiomyoplasty stimulation vs. Unstimulated state was evaluated on Primary functional properties of the heart (pressure-volume relation). Dynamic cardiomyoplasty stimulation in the nonfailing heart increased contractility but did not augment cardiac output or ejection fraction due to a simultaneous decrease in end-diastolic volume.
