A Prospective Multicenter Registry on Coronary Function Tests Organized by the Belgian Working Group on Coronary Microcirculation

What this Trial Is About

Researchers are conducting a prospective, multicenter registry to observe the real-world use of coronary function tests in routine Belgian medical practice. These tests may include bolus thermodilution measurements of coronary microvascular function and invasive vasoreactivity tests using acetylcholine. The study aims to understand how often these tests are performed, the reasons for testing, and the frequencies of coronary microvascular dysfunction and coronary artery vasospasm. Participants scheduled for coronary function tests will have data collected from their medical records regarding cardiovascular risk factors, past medical history, non-invasive test results, procedural details, and follow-up visits. There are no study-specific visits planned. Optionally, participants may complete questionnaires about their anginal symptoms and quality of life. No interventions are administered as part of this observational study. Participants' involvement includes routine data collection from medical files over a follow-up period of up to five years. Researchers will measure the frequency of coronary microvascular dysfunction and coronary artery vasospasm, as well as describe predictors for these conditions and major adverse cardiovascular events over one and three years among different patient groups. The study is organized by the University Hospital, Antwerp, and aims to provide valuable insights into coronary function testing practices and outcomes.
