A percutaneous dose of CD34-positive cells appeared to ease ischemia and improve symptoms in coronary microvascular dysfunction, the ESCaPE-CMD pilot study showed.
Microvascular function as measured by coronary flow reserve (CFR) improved from a mean 2.08 at baseline to 2.68 at 6 months (P=0.0045), a "very remarkable improvement," Timothy Henry, MD, of The Christ Hospital in Cincinnati, reported at the virtual annual conference of the Society for Cardiovascular Angiography and Interventions (SCAI).
