The GWTG registry was queried for patients >18 years old with a TIA or a minor AIS (NIHSS <5), who were admitted to a single hospital network between January 2018 and December 2021. Demographics collected including age, race, gender, and BMI. Patients on concurrent anticoagulation were excluded. We evaluated antiplatelet discharge practices at the tertiary stroke center vs the entire network, among men vs. women, African Americans (AA) vs whites, age 18-70 vs >70 years, and across BMI.
Among 2953 patients with a TIA or minor AIS, the mean age was 67.3 (SD +/- 13.8 years), with 42% >70 years of age. 47.8% were women; 37% were AA; 60% were white. DAPT was prescribed at the time of discharge to 40% of patients overall. Gender was a significant factor with men (43%) more likely to get prescribed DAPT than females (37%) (p=.002). While BMI did not have a lone effect on number of antiplatelets (AP) prescribed, when it was included as a covariate, there was a significant effect on the number of AP prescribed; with the higher the BMI, the less likely patients were to receive DAPT.
