Radiation-Induced Cardiac Dysfunction: Optimizing Radiation Delivery and Postradiation Care.

Area of Science:

• Oncology
• Cardiology
• Radiotherapy

Background:

• Thoracic radiation therapy (RT) is a common cancer treatment.
• Over 60% of patients undergoing thoracic RT may develop radiation-induced cardiac dysfunction (RICD).
• RICD arises from collateral radiation dose to the heart.

Purpose of the Study:

• To review risk factors associated with RICD in thoracic cancer patients.
• To explore the potential of electronic medical record (EMR) systems in managing RICD.
• To inform radiation oncologists and physicians on preventing, detecting, and treating RICD.

Main Methods:

• Literature review of factors contributing to RICD.
• Discussion of RT dose, concurrent treatments, and patient cardiometabolic health.
• Exploration of automated tracking in EMRs for RICD risk management.

Main Results:

• Key risk factors for RICD include radiation dose to cardiac structures, other cancer therapies, and patient cardiometabolic status.
• Automated tracking in EMRs can identify at-risk patients.
• Proactive management strategies can be implemented based on identified risk factors.

Conclusions:

• RICD is a significant concern for thoracic cancer patients receiving RT.
• Comprehensive risk assessment incorporating RT dose, treatment history, and patient health is crucial.
• EMR integration for automated risk tracking offers a promising approach to mitigate RICD.
