Help advance healthcare for Peripheral Artery Disease (PAD) in a way never before possible!

Peripheral artery disease (PAD) affects nearly 10 million people in the United States. That is 1 out of every 12 adults over 40. PAD limits blood flow to the lower body, especially the legs, resulting in calf muscle aching or cramping symptoms that become worse with exercise and improves only with rest. Doctors can treat the blockages in the arteries that cause these symptoms but don’t get to monitor treated or untreated patients often enough, only during clinic visits. This leaves a huge gap in our understanding of how PAD symptoms change over time.

Stanford University researchers welcome you to use VascTrac to track your symptoms and walking activity. With your permission, the VascTrac PAD app uses questionnaires and walking data from your phone.VascTrac then uses military-grade security to store and analyze the data. We find patterns between medical information and walking data to gain new insights about PAD.
No matter if you are a patient with PAD, a family member of someone with PAD, or just someone who wants to advance healthcare, we welcome you to join!

Let’s lead the fight against PAD, together.

Key Features:
- Unique algorithm to passively calculate the greatest distance you walk every day without stopping.
- A walking test activity to let you test and document how far you can walk before symptoms set in.
- Share insights and partner with researchers
- Learn more about PAD through resources provided

- Own an Apple iPhone 5S or newer
- Are 18 years or older

Participating in this study lays the foundation to potentially change the way we practice medicine by personalizing our approach to surveillance.
