Our system calculates the possibility of heart failure risk, for patients who have had a heart attack, a few days in advance. When the system changes a patient risk group, the medical personnel is informed about the change. After the notification, the cardiologist decides on how to interact with the patient. At this stage, the cardiologist is the most important player in the process. We suggest the risk group change but we do not inform patients automatically. This is the doctor’s role and we only support it by advanced early prediction.
