Key result
DCM is linked to increased LA volumes, reduced reservoir and conduit functions, and decreased LA strain.
Why the study?
Left atrial size predicts adverse cardiovascular outcomes, and progressive LV diastolic dysfunction alters LA filling and emptying components.
Does conventional echocardiography and strain imaging detect left atrial dysfunction in patients with dilated cardiomyopathy compared to healthy controls?
Population
50 patients with DCM (NYHA class I to IV and normal sinus rhythm) and 10 healthy control subjects
Comparison
Patients with DCM vs healthy control subjects

LA assessment via echo/strain may refine DCM evaluation; leaves open prognostic value and therapeutic implications pending prospective data.
Case-Control (n=60)
Does conventional echocardiography and strain imaging detect left atrial dysfunction in patients with dilated cardiomyopathy compared to healthy controls?
Left atrial systolic and diastolic dysfunction assessed by conventional and speckle tracking echocardiography is present in DCM patients and correlates with heart failure symptom severity.
Uday Saddam Almaliki (2026) conducted a case-control in Dilated cardiomyopathy (n=60). Dilated cardiomyopathy vs. Healthy control subjects was evaluated on Left atrial volumes, reservoir, conduit, and pump functions, and strain parameters. Dilated cardiomyopathy was associated with significantly increased left atrial volumes, reduced reservoir and conduit functions, and decreased left atrial strain compared to healthy controls.
