Strain Pattern on Electrocardiogram Is Associated with Increased Carotid Intima-Media Thickness in Patients with Aortic Valve Stenosis.

Background: Coronary artery disease is present in at least 30% of patients with degenerative aortic stenosis (AS). Atherosclerosis also performs an important role in the progression of AS, because of the similarities of pathological mechanisms in both conditions. The electrocardiogram (EKG) strain pattern is associated with structural myocardial change and subendocardial ischemia and has been worldwide used as a marker of AS severity.
