Key result
Optimized latissimus dorsi stimulation in dynamic cardiomyoplasty significantly increased stroke volume by a mean of 20% (P<0.01) compared to unassisted beats.
Why the study?
Does optimized latissimus dorsi stimulation improve stroke volume and cardiac function in cardiomyoplasty patients?

Effect estimate: mean increase of 20%
p-value: p=<.01
Optimization of synchronization interval and stimulus strength in dynamic cardiomyoplasty significantly improves stroke volume and peak ejection rate, explaining clinical benefits not seen at standard settings.

Optimization may augment hemodynamics in cardiomyoplasty; hypothesis-generating and requires prospective validation before practice change.
Schreuder et al. (1995) studied Cardiomyoplasty (n=9). Latissimus dorsi muscle stimulation vs. Unassisted beats (5-second period without stimulation) was evaluated on Stroke volume (SV) (mean increase of 20%, p=<.01). Optimized latissimus dorsi stimulation in dynamic cardiomyoplasty significantly increased stroke volume by a mean of 20% (P<0.01) compared to unassisted beats.
