Why the study?
Does chest conformation influence myocardial strain parameters in healthy pregnant women?
Does chest conformation influence myocardial strain parameters in healthy pregnant women?
Myocardial strain changes in healthy pregnancy may be an artifact of chest conformation and extrinsic compression rather than true myocardial dysfunction.
Strain changes in healthy pregnancy warrant cautious interpretation; leaves open whether chest conformation confounds intrinsic function assessment.
Myocardial strain impairment during healthy pregnancy may not reflect intrinsic myocardial dysfunction but rather intraventricular dyssynchrony related to a narrow antero-posterior chest diameter and rise in the diaphragm, with consequent extrinsic myocardial compression.
