Sato et al reported a score for predicting mortality of a patient in Japan with aortic stenosis. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple instututions in Japan and members of the CHART-2 Investigators.
Patient selection: Japanese patient with aortic stenosis
Outcome: mortality
Parameters:
(1) gender
(2) age in years
(3) aortic peak flow (APF) in meter per second
(4) anemia (hemoglobin < 13 g/dL for male, < 12 g/dL for female)
(5) serum albumin in g/dL
(6) chronic kidney disease (eGFR <= 60 mL per min per 1.73 square meter)
(7) NYHA class

total score =
= SUM(points for all 7 parameters)
Interpretation:
• minimum score: 0
• maximum score: 18
• The higher the score the greater the risk of overall mortality.
