Key result
Left atrial active emptying fraction was significantly lower in idiopathic dilated cardiomyopathy (18%) compared to ischemic dilated cardiomyopathy (32%) and controls (36%) (P<0.05).
Why the study?
Is left atrial systolic function depressed in idiopathic dilated cardiomyopathy compared to ischemic dilated cardiomyopathy and normal controls?
Observational (n=51)
Is left atrial systolic function depressed in idiopathic dilated cardiomyopathy compared to ischemic dilated cardiomyopathy and normal controls?
Absolute Event Rate: 18% vs 32%
p-value: p=<0.05
Left atrial systolic function is depressed in idiopathic dilated cardiomyopathy but preserved in ischemic dilated cardiomyopathy, suggesting a primary left atrial myopathy in the idiopathic form.

May indicate primary left atrial myopathy in idiopathic dilated cardiomyopathy; cross-sectional data leaves open causal and prognostic implications.
Triposkiadis et al. (1999) conducted an observational in Dilated cardiomyopathy (n=51). Idiopathic dilated cardiomyopathy vs. Ischemic dilated cardiomyopathy and normal controls was evaluated on Left atrial active emptying fraction (ACTEF) (p=<0.05). Left atrial active emptying fraction was significantly lower in idiopathic dilated cardiomyopathy (18%) compared to ischemic dilated cardiomyopathy (32%) and controls (36%) (P<0.05).
