This study aimed to evaluate whether HR variability within 24 h postIVT predicts early neurological deterioration (END) and 3-month functional outcomes using machine learning.  \nMethods: This retrospective analysis included AIS patients without atrial fibrillation (AF) who received IVT at Dongguan People’s Hospital between January 2017 and December 2022. Hourly HR metrics (mean HR, SD, coefficient of variation [CV]) were analyzed. Primary outcomes were END (≥4-point NIHSS increase within 72 h) and poor 3-month outcomes (mRS ≥ 3) . Machine learning models were developed and validated via receiver operating characteristic (ROC) analysis.  \nResults: Among 381 patients, logistic regression identified NIHSS on admission (OR = 1. 287, p \u003C 0.001), maximum HR (OR = 0.956, p = 0.023), minimum HR (OR = 1.027, p = 0.001), and HR SD (OR = 1.356, p = 0.002) as independent predictors of poor 3-month outcomes. HR CV also showed significance but correlated strongly with SD. A machine learning model integrating onset-totreatment time, NIHSS, and HR parameters (max/min HR, mean HR, SD) achieved an area under the ROC curve (AUC) of 0.82 for predicting 3-month outcomes. No HR metrics were significantly associated with END.  \nConclusion: In AIS patients without AF, early HR dynamics—particularly maximum HR, minimum HR, SD, and CV—strongly correlate with 3-month functional outcomes after IVT. The machine learning model demonstrated high predictive accuracy, highlighting the potential of real-time HR monitoring for risk stratification and personalized management i","cbCaikpZJQvOlkPe","https://ap.wps.com/l/cbCaikpZJQvOlkPe","pdf",1357841,1,11,"English","en",105,"# Background\n# Methods\n# Results\n# Conclusion\n# Key findings","[{\"question\":\"What question does the study address about early heart rate in AIS after IVT?\",\"answer\":\"The study evaluates whether heart rate variability within 24 hours after IVT predicts early neurological deterioration and 3-month functional outcomes using machine learning.\"},{\"question\":\"Which patient group and data window were analyzed in the methods?\",\"answer\":\"The analysis included AIS patients without atrial fibrillation who received IVT at Dongguan People’s Hospital between January 2017 and December 2022, using hourly HR metrics during the first 24 hours.\"},{\"question\":\"Which HR metrics were significant for predicting poor 3-month outcomes?\",\"answer\":\"Independent predictors included admission NIHSS, maximum HR, minimum HR, and HR SD, while HR CV was also significant though strongly correlated with SD.\"},{\"question\":\"Did any HR metrics predict early neurological deterioration (END)?\",\"answer\":\"No HR metrics were significantly associated with END in this study.\"}]","Early heart rate predicts 3-month outcomes in acute ischemic stroke patients receiving intravenous thrombolysis -
