Does frailty status measured by the Katz Index predict short- and long-term morbidity and mortality after TAVI better than commonly used risk scores?
The Katz Index is a simple and reproducible measure of frailty that strongly predicts early and late adverse outcomes after TAVI, outperforming standard risk scores.
Frailty status measured by the Katz Index represents a powerful predictor of adverse early and late outcome after TAVI, whereas commonly used risk scores lack calibration and discrimination in a TAVI-specific patient cohort. Therefore, we propose the incorporation of this simple and reproducible measure into pre-TAVI risk assessment.
Puls et al. (2014) studied this question.
