Cardiologists have employed these vasoreactivity tests to conveniently diagnose the presence of coronary spasms in patients with all VSA. The majority of VSAs may have lower disease activity than VA cases. We have summarized the usefulness of spasm provocation tests in patients with VA and VSA. A positive-provoked spasm diagnosed by standard vasoreactivity testing may indicate a disease state similar to that of VA, whereas a negative-provoked spasm after standard vasoreactivity testing may indicate a lower disease state than that of VA.
