Mean Heart Dose (MHD) Risk Predictor: Explanation and Clinical Context The Mean Heart Dose (MHD) is a critical metric in radiation therapy, especially for patients undergoing treatment for left-sided breast cancer. Studies have shown a linear relationship between MHD and the risk of subsequent major cardiac events, with a 7.4% relative increase per 1 Gy of MHD. This means that for every gray (Gy) increase in MHD, the risk of cardiac events increases by 7.4%.
