Key result
Patients with dilated cardiomyopathy exhibited significantly larger left atrial volumes (75.57 ml) compared to normal control subjects (58.57 ml, p<0.016).
Why the study?
The degree of LA remodeling and the pathophysiologic determinants of LA volume in patients with LV systolic dysfunction and dilated cardiomyopathy needed to be analyzed.
Population
Patients with DCMP and sex-matched controls
Comparison
Patients with DCM vs normal control subjects

LA volume assessment may aid DCM evaluation; leaves open its independent prognostic value and causal determinants.

In patients with dilated cardiomyopathy, LA volume is significantly increased compared to controls, and is primarily determined by Em and LV ejection fraction.
Reddi Basha Saheb Shaik (2020) conducted a case-control in Dilated cardiomyopathy with LV systolic dysfunction (n=70). Dilated cardiomyopathy vs. Healthy controls was evaluated on Left atrial volume (LAV) (p=<0.016). Patients with dilated cardiomyopathy exhibited significantly larger left atrial volumes (75.57 ml) compared to normal control subjects (58.57 ml, p<0.016).
