OnDemand: Nuclear Imaging in Women and Special Populations: From Diagnosis to Treatment and Beyond-Invasive Testing for Microvascular Disease: How and When

Video Transcription

Video Summary

The video is a presentation on invasive testing for microvascular disease. The presenter discusses the definition of coronary microvascular dysfunction and its causes, such as atherosclerosis and cardiovascular risk factors. They explain different methods to evaluate microcirculatory function, including measuring coronary flow reserve (CFR) and the index of microvascular resistance (IMR) using invasive techniques in the cath lab. The video highlights the clinical criteria for diagnosing microvascular angina and the recommended tests for evaluating patients with suspected non-obstructive coronary artery disease. It also discusses the prevalence and prognostic implications of microvascular dysfunction and vasospasm. The presenter emphasizes the importance of individualized treatment based on the specific mechanism of anginal symptoms. The video concludes by mentioning a study demonstrating improved patient-reported outcomes with a stratified approach to anti-anginal therapy based on invasive testing results.
