HF Defender

Web & mobile app development

Client: Prevail Heart Clinics

Industry: Healthcare


Dr. Kevin Courville, a Louisiana cardiologist, had a problem. He needed to reach and track patients who had experienced heart problems but who lived in remote areas and couldn’t attend regular follow-up appointments. He needed an application to track patients’ vital signs in the hopes of preventing future medical incidents.


Dr. Courville had a simple idea, but he needed a sophisticated solution. Vinformatix brainstormed with him to understand the details of the project, wrote requirements and developed HF Defender, a web-based software system and mobile application for iOS and Android, for the doctors at Prevail Heart Clinics. Using the system, patients can easily enter their vitals on their smartphone or computer, doctors can view the information, and medical staff can track changes in medications and send patients alerts and messages.


Using HF Defender, Dr. Courville was able to reduce post-hospital visits while also improving communication between doctor and patient. He was so pleased with the results that he came back to Vinformatix to update the software and add new features like medication management and an at-a-glance dashboard.
