Traditional risk markers such as cTnT, NT-proBNP, CRP and eGFR gave poor discrimination for concomitant AS and ATTR-CM with AUCs between 0.48–0.53 (p > 0.78 for all), while age gave an AUC of 0.72 (p = 0.003) and a propensity score using age and all cardiac markers (PS1) gave an AUC of 0.74, p < 0.001. This evidence concerns the gene TNNT2 and aortic stenosis.
