Multicenter Registry of Coronary Flow-Derived Indexes for Coronary Microvascular Disease (Multicenter FLOW-CMD Registry)

Condition(s) studied

Investigational drug(s) / intervention(s)

Invasive physiologic assessment: All coronary physiologic parameters are measured following diagnostic angiography. Resting pd/pa, FFR, CFR and IMR will be calculated using coronary physiologic parameters. In patients treated by PCI, post-PCI physiologic assessment including CFR, IMR, and FFR will be performed.

Intravascular imaging: By the operator's discretion, stent-optimization will be performed under intravascular imaging devices (IVUS \[Boston Scientific, Natick, Massachusetts, USA\] or OCT \[Abbott Vascular\], St. Paul, MN, USA\]).

Study summary

Multicenter FLOW-CMD registry is a prospective, multi-center, registry study.

The aim of the study is to evaluate prognostic implications of coronary microvascular disease (CMD) in patients with ischemic heart disease (IHD) undergoing revascularization decision using FFR or other non-hyperemic pressure ratios.

Eligibility

Primary outcome measure(s)

• Patient-oriented composite outcomes (POCO) — 1 year after last patient enrollment
  a composite of all-cause death, MI, any repeat revascularization, or admission for heart failure
