Multicenter Prospective Assessment of Coronary Microvascular Dysfunction: Primary Results of the FlowLab Study.

ABSTRACT:

Background

Coronary microvascular dysfunction (CMD) and vasospastic angina (VSA) are common, yet underdiagnosed. Existing studies of invasive CMD/VSA assessment have specified patient selection and procedural technique, with little known about testing use in real-world practice.

Objectives

The purpose of the study was to observe procedural and therapeutic decision-making for patients undergoing invasive CMD/VSA assessment.

Methods

FlowLab was a multicenter, prospective study of patients with possible CMD in whom the treating physician used the CoroFlow bolus thermodilution system to measure coronary flow reserve and index of microcirculatory resistance (IMR). As the purpose was to observe how testing is performed in current practice, procedural technique, including wh
