The heart failure preserved ejection fraction (HFpEF) accounts for 40–50% of all causes of heart failure. For HFpEF, identification of strain disturbances where systolic function is seemingly preserved is a decisive step toward revealing hidden heart damage. Recently, the novel technique of feature tracking imaging (FTI) was introduced for myocardial strain measurement directly from conventional cine images. We demonstrated that FTI allows for detailed strain assessment with acceptable correlation with the tagging method. In particular, global circumferential strain, which cannot be detected by analysis using cine images, may possibly serve as a sensitive and early marker of cardiac dysfunction.
