Vibrometer Based Pulse Wave Analysis for Arterial Stiffness and Ischemic Heart Disease Risk Assessment

This study is testing a new device that measures pulse wave velocity (how fast a pressure wave travels through your arteries) using a small vibrating sensor held gently against the skin — similar to how a tuning fork works. Stiffer arteries are linked to higher risk of heart attack, and this tool may offer an easier way to assess that risk without complex procedures. **You may be eligible if...** - You are an adult patient receiving routine care at one of the study clinics, or have been separately invited to participate - You are able to understand the study information (in Swedish or English) and give consent **You may NOT be eligible if...** - You have cognitive impairment that prevents understanding the study - You cannot communicate in Swedish or English - You have a severe or terminal illness (such as active sepsis, severe COPD, or metastatic cancer) that makes participation unsafe Talk to your doctor to see if this trial is right for you.
