Regional wall function is an important parameter in the diagnosis of heart disease. Qualitative assessment of wall function has limitations in terms of inter-observer variability. Strain is a new way to obtain quantitative wall function. Magnetic Resonance Imaging (MRI) gives the opportunity to measure strain in both radial and longitudinal directions. We hypothesized that by using only assessment of strain measured acutely after myocardial infarction it is possible to identify which artery was affected.
The experienced observer blinded to patient data correctly identified the affected vessel in all 18 patients compared to angiographic findings. Figure 1 shows three examples of polar plot visualizations of myocardial strain with patients with LAD, LCx, and RCA, respectively.
MRI strain analysis can be used to identify affected vessel after acute myocardial infarction, and is therefore a promising technique to quantify regional wall function.
