Insights
Cardiac parameters on chest CT scans predict successful recanalization in acute ischemic stroke (AIS) patients undergoing thrombectomy. This finding aids in predicting treatment outcomes for AIS.
Area of Science:
- Cardiology
- Neurology
- Radiology
Background:
- Acute ischemic stroke (AIS) is the most common type of stroke.
- The brain-heart interaction is crucial in stroke pathophysiology and treatment response.
- Predicting successful recanalization after thrombectomy is vital for patient outcomes.
Purpose of the Study:
- To investigate the association between cardiac parameters visible on routine preoperative chest CT scans and successful recanalization in AIS patients treated with thrombectomy.
- To identify independent predictors of recanalization from cardiac CT findings.
- To develop and validate a predictive model (nomogram) for recanalization.
Main Methods:
- Retrospective analysis of 215 AIS patients who received thrombectomy within 24 hours.
- Admission non-contrast chest computed tomography (NCCT) was used to assess cardiac parameters.
- Successful recanalization was defined by a modified Treatment in Cerebral Ischemia (mTICI) score of 2b-3.
- Multivariable logistic regression, ROC analysis, calibration, and decision curve analysis were employed.
Main Results:
- The study included 215 patients (72 years median age, 63.7% male) with prevalent hypertension, atrial fibrillation, and pleural effusion.
- Successful recanalization was achieved in 80% of patients (172/215).
- Independent predictors of successful recanalization included mean arterial pressure, left pulmonary artery diameter, RV/A ratio, septal angle, and intraventricular septal angle.
- The developed nomogram demonstrated strong predictive performance (AUC of 0.774) with good calibration and clinical utility.
Conclusions:
- Cardiac parameters assessed on routine preoperative chest CT scans are significantly correlated with recanalization success after thrombectomy in AIS patients.
- The developed nomogram provides a reliable tool for clinical risk stratification and prediction of thrombectomy outcomes in AIS.
- These findings highlight the utility of incidental cardiac findings on chest CT for predicting neurological outcomes.
Abstract:
Purpose: Acute ischemic stroke (AIS) is the most prevalent stroke subtype. Given the brain-heart interaction, this study investigated the association between cardiac parameters on admission routine preoperative chest CT and recanalization following thrombectomy in AIS patients. Method: We retrospectively analyzed 215 AIS patients (August 2018-June 2022) who underwent admission of none contrast chest computed tomography (NCCT) and thrombectomy within 24 h. Successful recanalization was defined as modified Treatment in Cerebral Ischemia (mTICI) score 2b-3. Multivariable logistic regression identified independent predictors. A nomogram was developed and validated using ROC, calibration, and decision curve analyses. Result: The cohort had a median age of 72 years; 63.7% were male. Hypertension (65.1%), atrial fibrillation (25.1%), and pleural effusion (56.3%) were prevalent. Successful recanalization occurred in 172 patients (80%). Independent predictors included mean arterial pressure (OR: 1.022, CI: 1.003-1.041, p = 0.025), left pulmonary artery diameter (OR: 0.838, CI: 0.733-0.958, p = 0.010), RV/A ratio (standardized) (OR:1.908, CI: 1.293-2.817, p = 0.001), septal angle (OR: 1.055, CI: 1.018-1.094, p = 0.004), and intraventricular septal angle (OR: 0.973, CI: 0.952-0.995, p = 0.015). The model achieved an AUC of 0.774 (p < 0.001) with strong calibration and net benefit. Conclusions: Cardiac parameters on routine preoperative chest CT correlate with recanalization following thrombectomy in AIS patients. The developed nomogram offers a reliable tool for clinical risk stratification.
