For example, the system is used for detecting an occlusion in a cardiovascular system of a user. A computer-implemented method for detecting the occlusion includes generating a light within a predetermined spectral range, the light directed towards a reflective element at a predetermined angle. The method further includes receiving a reflected light caused by a reflection of the light off of a reflecting element that is in contact with the user's epidermis. The method further includes detecting a concentration of a predetermined biomarker in a biofluid in the cardiovascular system based on variations in amplitude of the reflected light. The method further includes determining an occlusion in the cardiovascular system based on the concentration of the predetermined biomarker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transdermal optical detection of cardiac biomarkers","description":"As described herein, a system includes an optical sensor, and a controller that detects progression of obstructive coronary artery disease using a sensor signal from the optical sensor.
