Women with acute coronary syndromes have lower rates of cardiac catheterization (CC) than men.

The objective of the RACE-CAR study was to determine whether sex/gender, age, risk level and patient preference influence physician decision making to refer patients for cardiac catheterization (CC).

Twelve clinical scenarios controlling for sex⁄gender, age (55 or 75 years of age), Thrombolysis in Myocardial Infarction risk score (low, moderate or high) and patient preference for CC (agreeable or refused⁄no preference expressed) were designed. Scenarios were administered to specialists across Canada using a web-based computerized survey instrument.

Primary endpoint:

Assessment of physician decision and referral patterns for cardiac catherization.

The co-Principal Investigator on the RACE-CAR study was Catherine Kreatsoulas, at the time a PhD student in epidemiology at McMaster University under the supervision of Sonia Anand.
