Abstract

As an integral aspect of health care, digital technology has enabled modelling of complex relationships to detect, screen, diagnose, and predict patient outcomes. With massive data sets, artificial intelligence (AI) can have marked effects on 3 levels: for patients, clinicians, and health systems. In this review, we discuss contemporary AI-enabled wearable devices undergoing research in the field of cardiovascular medicine. These include devices such as smart watches, electrocardiogram patches, and smart textiles such as smart socks and chest sensors for diagnosis, management, and prognostication of conditions such as atrial fibrillation, heart failure, and hypertension as well as monitoring for cardiac rehabilitation. We review the evolution of machine learning algorithms used in wearable devices from random forest models to the use of convolutional neural networks and transformers. We further discuss frameworks for wearable technologies such as the V3-stage process of verification, analytical validation, and clinical validation as well as challenges of AI integration in medicine such as data veracity, validity, and security and provide a reference framework to maintain fairness and equity. Last, clinician and patient perspectives are discussed to highlight the importance of considering end-user feedback in development and regulatory processes.

TL;DR

This review discusses AI-enabled wearable devices in cardiovascular medicine, covering machine-learning evolution, applications in atrial fibrillation, heart failure, hypertension, and cardiac rehabilitation, and challenges in validation, bias, regulation, data quality/security, and end-user perspectives. It concludes that wearables show promise but clinical implementation remains in infancy without large-scale validation and equitable, regulated integration.

Key findings

  • Atrial fibrillation detection is described as the most successful wearable application: the Apple Heart Study PPG/DNN algorithm showed a c-statistic of 0.97 and 84% positive predictive value vs 12-lead ECG; a smart ring had 96.9% diagnostic accuracy; the Amazfit Health Band had 96% sensitivity, 98% specificity, and 97% accuracy; mSToPS continuous 1-lead ECG monitoring led to higher new AF diagnosis and increased anticoagulation and cardiology referral.
  • Heart failure applications include a 1-lead ECG CNN that correctly identified left ventricular systolic dysfunction abnormalities in 90% of ECGs, with a noise-adapted AUROC of 0.87; Attia et al. reported an AUC of 0.885 using Apple Watch 1-lead ECGs; LINK-HF predicted HF hospitalization with 76%-88% sensitivity and 85% specificity; TRUE-HF is evaluating a smartwatch paired with a transformer AI model.
  • Hypertension and cardiac rehabilitation findings include cuffless PPG wristbands and multimodal AI for blood pressure; the MiCORE study reported a 43% reduction in 30-day rehospitalization and significant cost reductions using an Apple Watch and Bluetooth blood pressure cuff; a meta-analysis of 23 randomized trials found home-based cardiac rehabilitation as effective as centre-based care; a meta-analysis of 9 trials found wearable monitoring superior to no device for exercise adherence.
  • Equity and implementation concerns include underuse among those with cardiovascular disease (fewer than 18% with established CVD and 23% at risk vs 29% of the general population); racial bias in pulse oximetry and a 30% absolute error during activity in darker skin tones; the V3 framework and 6 equitable AI principles; and patient survey data (>500 individuals with AF: 79% interested in mobile AF detection, about two-thirds interested in continuing; 72% willing to share data with a physician vs 53% with insurer or manufacturers).

Methods

  • Narrative review of contemporary AI-enabled wearable devices in cardiovascular medicine; no primary data collection or original patient cohort is reported.
  • Synthesizes published literature, clinical trials, and frameworks such as the V3 verification/analytical validation/clinical validation process and equitable AI principles, with tables, figures, and hypothetical case vignettes (Ms S. in 2024 and 2028).
  • Main analysis is a qualitative synthesis of device types, machine-learning algorithms (random forest, support vector machine, FCNN, RNN, LSTM, CNN, transformers), cardiovascular applications, and implementation challenges.

Limitations

  • Stated in the paper: there are limited examples of successful clinical applications; AI-based tools have yet to demonstrate improved patient outcomes at scale; many current AI applications rely on antiquated labels and primitive decision tools; large-scale clinical trials and external validation are lacking; there are no established clinical standards of care for wearable sensors; and regulatory oversight is lacking.
  • Stated in the paper: challenges include data veracity, validity, and security; bias and inequity; sensor variability; proprietary data archives; reidentification risk; and a paucity of data on patient views and perspectives.
  • Evident from the text: as a narrative review, it does not report a systematic search strategy, risk-of-bias assessment, or meta-analysis; several cited trials are ongoing or have results anticipated later (e.g., Heartline in 2025), and the case vignettes are illustrative rather than empirical.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • iCARE-AF anticoagulation claim cites an AF-detection wristband study

    Minor

    The cited reference concerns a wristband algorithm for detecting AF, whereas the text attributes findings about on-demand anticoagulation to it.

  • AF-detecting PPG ring claim cites a blood-pressure bioimpedance paper

    Minor

    The cited reference is titled as a study of cuffless blood-pressure monitoring using ring bioimpedance, not PPG-based AF detection.

  • V3 stage is called both analytical validation and analytical verification

    Minor

    The framework is introduced with analytical validation as its second stage, but the description calls that stage analytical verification.

  • RADAR-HF has two different expansions

    Minor

    The Table 2 legend and its RADAR-HF row give different study names for the same acronym.

  • REMOTE-CR claim cites a heart-failure monitoring trial

    Minor

    Reference 43 is titled as a trial of wireless pulmonary-artery monitoring in chronic heart failure, not the remote cardiac-rehabilitation trial described in the text.

  • Ongoing smartwatch anticoagulation trial cites a 2013 device study

    Minor

    The cited reference describes the diagnostic utility of a leadless arrhythmia-monitoring device, rather than the ongoing smartwatch-guided anticoagulation trial described in the text.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
