Insights
Esmolol effectively reduces heart rate for emergency coronary CT angiography (CTA) in patients with high heart rates or inability to hold their breath. This rapid method, combined with AI analysis, ensures effective diagnosis without compromising image quality.
Area of Science:
- Cardiovascular Imaging
- Radiology
- Pharmacology
Background:
- Coronary computed tomography angiography (CTA) is crucial for emergency patients.
- High heart rates and inability to hold breath impede CTA quality in critically ill patients.
Purpose of the Study:
- To evaluate a rapid and effective method for coronary CTA in emergency settings.
- To assess the utility of esmolol for heart rate reduction and AI for image analysis.
Main Methods:
- Intravenous esmolol was administered for rapid heart rate reduction under ECG monitoring.
- Coronary CTA was performed using a 640-slice high-speed CT scanner.
- Artificial intelligence software was used for subsequent reconstruction analysis.
Main Results:
- The diagnostic rate for coronary artery segments with excellent/good CTA images was 95.4% in the esmolol group versus 91.1% in the control group.
- Esmolol achieved rapid heart rate reduction with a short half-life and minimal side effects.
- No significant statistical difference was found between the groups (P > 0.05).
Conclusions:
- Esmolol injection is a safe and effective method for rapid heart rate control in patients undergoing coronary CTA.
- The combination of esmolol and AI-powered analysis offers a novel approach for efficient coronary CTA in emergency patients.
- This method eliminates the need for breath-holding or extensive preoperative preparation.
Objective:
To investigate a rapid and effective method for the examination of coronary CTA in emergency patients requiring coronary CTA examination, who have faster heart rate (≧80 bpm) or cannot cooperate with the examination due to the inability of breath holding at poor physical conditions.
Methods:
Before coronary CTA examination, with the ECG monitoring, intravenous injection of esmolol was given to achieve rapid heart rate reduction. Without the patient's cooperation, coronary CTA examination was then performed in a quick and effective manner using the 640-slice high-speed CT. The diagnosis report was obtained through the subsequent reconstruction analysis using artificial intelligence software.
Conclusion:
Esmolol injection can rapidly reduce the heart rate of normal people during exercise and at rest, and the steady blood concentration can be reached in 2 minutes. The half-life is about 5 minutes, with short duration and fewer side effects on patients. The diagnostic rate of coronary artery segment using (excellent + good) CTA image of the patients with esmolol and artificial intelligence analysis in the experimental group was 95.4%, while the diagnostic rate was 91.1% in the control group, and there was no significant statistical difference between the two groups (P > 0.05). Esmolol injection can rapidly reduce heart rate in patients with high heart rate, without holding breath or long-term preoperative preparation; the combination with the analysis of subsequent artificial intelligence reconstruction is a new method for rapid and effective coronary CTA examination in all patients.
