Dr. Jan Verwerft studied medicine at KU Leuven, where he completed his clinical training in cardiology with residencies at OLV Hospital Aalst, University Hospital Leuven, and AZ Delta Roeselare. He later pursued a heart failure fellowship at the Erasmus MC Thoraxcenter. Since 2006, he has been practicing as a cardiologist at the Heart Center of JESSA Hospital Hasselt, where he focuses on diagnosing and treating heart failure with preserved ejection fraction (HFpEF) in a specialized dyspnea clinic. His main clinical and research interest lies in the integration of exercise echocardiography with cardiopulmonary exercise testing (CPETecho). He obtained his PhD from Hasselt University in 2025, successfully defending his thesis entitled “Cardiopulmonary exercise testing combined with echocardiography for the evaluation of exercise limitations: unmasking deficits in the oxygen cascade.”
