U.S., Aug. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07103317) titled 'Comprehensive Coronary Physiology in Patients With Angina With Nonobstructive Coronary Arteries - Czech Republic' on July 16.
Brief Summary: Coronary artery disease (CAD) is a leading cause of morbidity and mortality. While cardiologists have been focused on discrete, visible stenoses of coronary arteries, there is increasing awareness of the importance of microcirculation and vasospastic disorders in causing angina.
