The study aimed to assess fast strain-encoded (SENC) cardiac magnetic resonance (CMR) and native T1 mapping in distinguishing between hypertrophic cardiomyopathy (HCM) and cardiac amyloidosis. Ninety-nine patients (57 with HCM, 42 with amyloidosis) were analyzed for LV parameters, myocardial strain (global and segmental), and T1 values. HCM patients showed evenly distributed strain, while amyloidosis patients exhibited apical sparing with less impaired apical strain. T1 values were significantly higher in amyloidosis. The T1-to-basal segmental strain ratio effectively differentiated between conditions (Sensitivity = 85%, Specificity = 77%, AUC = 0.90), highlighting its potential in non-contrast CMR protocols for accurate diagnosis.
Systematic Review and Meta-Analysis for the Value of Cardiac Magnetic Resonance Strain to Predict Cardiac Outcomes
Cardiac magnetic resonance (CMR) is the gold standard for the diagnostic classification and risk stratification in most patients with cardiac disorders. The aim of the present study was to investigate the ability of Strain-encoded MR (SENC) for the prediction of major adverse cardiovascular events (MACE).
