Summary
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.

01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
