Research
Overview
Platelets play a central role in atherosclerosis and treatment relies in anti-platelet therapies. However, there are different clinical phenotypes of atherosclerosis. Combining basic and clinical research approach to various clinical phenotypes, we are investigating the roles of platelets in coronary and peripheral vascular disease.
