Summary
The Applanation Tonometry in Giant Cell Arteritis (ATOM-GCA) study will answer the following questions: 1. How does PWV, measured by applanation tonometry of temporal arteries, differ between patients with and without a final diagnosis of GCA (based on pre-defined criteria 6 months after inclusion)? 2. What is the diagnostic accuracy and positivity cutoff of the PWV, measured by applanation tonometry, in detecting: 1. A clinical diagnosis of GCA (based on pre-defined criteria 6 months after inclusion)? 2. Inflammation of temporal arteries on high-resolution ultrasound? 3. What is the acceptability and adherence of repeat applanation tonometry during the follow-up period in patients with GCA?
