Noninvasive identification and therapeutic implications of supernormal left ventricular contractile phenotype

Abstract excerpt

Left ventricular (LV) function is typically evaluated through LV ejection fraction (EF), a robust indicator of risk, showing a nonlinear increase in mortality rates below 40%. Conversely, excessively high EF values (> 65%) also correlate with elevated mortality, following a U-shaped curve, with its nadir observed between 50% and 65%. This underscores the necessity for improved identification of the hypercontractil...
