*Obstructive plaque can stimulate “collateral circulation,” or the formation of new blood vessels. Oxygen-deprived cells downstream from the obstruction release chemical growth factors that signal primitive vascular cells to invade the hypoxic tissue, assembling into a plexus of new hollow tubes that link up into a complex network. This process, called angiogenesis, ensures that blood vessels permeate every region of the body. These new blood vessels—the heart’s attempt to repair itself—limit the damage caused by a heart attack.

*A few years later, Sones said that the era of angioplasty was “the best time in medical history to have been alive, and I am deeply grateful for the privilege.”
