Chlamydia pneumoniae and Acute Coronary Syndrome/DRS. GRAYSTON AND CANNON REPLY

Drs. [Wong BYL] and [Judy Gnarpe, Ph.D.] suggest that baseline serologic tests for chlamydia should have been used to identify participants for our trials. Baseline seralogic data were collected in both studies but were not used as admission criteria because we believed that there is not sufficient evidence that either the presence or the absence of C. pneumoniae antibody clearly identifies adults at increased risk of coronary events.
