Systolic thickening and thinning of the septum and posterior wall in patients with coronary artery disease, congestive cardiomyopathy, and atrial septal defect.
Why the study?
Does echocardiographic systolic wall thinning and thickening differ among patients with coronary artery disease, congestive cardiomyopathy, atrial septal defect, and normal controls?
Structured PICO
Does echocardiographic systolic wall thinning and thickening differ among patients with coronary artery disease, congestive cardiomyopathy, atrial septal defect, and normal controls?
P
Population
146 patients with acute myocardial infarction (n=40), chronic coronary artery disease (n=49), congestive cardiomyopathy (n=8), atrial septal defect (n=20), and no cardiac disease (n=29)
I
Intervention
Echocardiographic measurement of septal and posterior wall thicknesses and percent change with systole
C
Comparator
Patients with no cardiac disease (n=29)
O
Outcome
Septal and posterior wall thicknesses and percent change with systolesurrogate
Systolic thinning on echocardiography is indicative of an acute ischemic event, while abnormal wall motion can occur without abnormal thickening in conditions like atrial septal defect.

Implication
Systolic thinning may flag acute ischemia on echo; leaves open specificity versus cardiomyopathy or ASD.
