Valvular & structural heart diseaseCase-control study

Wearable SENsor to Diagnose and Assess SEverity of Aortic Stenosis (SENSE-AS)

JACC AdvPublished

  • prospective, single-center case-control study
  • controls age- and sex-matched to the severe aortic stenosis (AS) cohort

Authors' conclusion

A chest-worn multimodal wearable sensor accurately measures AV AT and predicts AV Vmax, supporting the feasibility of accessible, lower-cost tools for early detection and longitudinal monitoring of AS.

Study context

Population
Subjects with severe, moderate, and mild AS according to echocardiography guidelines, and controls without ASsubjects enrolled · severe AS 10 · moderate AS 10 · mild AS 10 · controls without AS 10
Participants
40 subjects
Comparison
Sensor-derived acceleration time (AT) vs Doppler-derived aortic valve acceleration time
  • severen = 10
  • moderaten = 10
  • mildn = 10
  • controlsn = 10
Outcome
Correlation between Doppler-derived AV AT and sensor-derived AT

Main finding

As reported in the abstract

r

0.85; 95% CI: 0.73-0.92; P < 0.001

Observational data: associations, not effects.

Secondary outcomes

AT by group

Progressively longer AT from controls through increasing AS severities
P < 0.01

Machine learning model predictions on unseen patient data vs aortic valve (AV) Vmax

r
0.76; 95% CI: 0.68-0.83; P < 0.001
  • model trained on a limited subset of AS patient recordings (n = 32)
