Introduction:
The majority of patients who present with acute ischemic stroke (AIS) have known stroke risk factors which are not optimally managed. It has been suggested that a CHADS-VASC score can assist with primary prevention by calculating future stroke risk. This however, has not been widely adapted in the primary care setting.
Methods:
From 2018-2019, 686 AIS patients were included in retrospective analysis. Data elements included: historical stroke risk factors, historical CHADS-VASC score, antiplatelet/anticoagulant use at time of presentation, discharge location, and mRS.
Results:
Of the 686 AIS patients, 77% were age

60, and 52% were male. Etiology subtypes were small vessel/lacunar 20%, large vessel 22%, cardioembolic 20%, undetermined 31% (cryptogenic 15%), and other determined 5%. On presentation, the majority of patients had 2 or more stroke risk factors and a calculated historical CHADS-VASC score

2 (Table 1). Over half of the patients with large vessel or small vessel/lacunar etiology were not on any antiplatelets and 53% of patients with known history of atrial fibrillation weren’t on anticoagulants. Forty-nine percent of patients had a mRS

3 at discharge.
Conclusion:
Patients with several stroke risk factors are sub optimally managed by primary care providers. Primary prevention education for PCPs in management of higher stroke risk individuals and additional analysis of the CHADS-VASC tool for this setting is needed. If widely adapted, this tool may prevent strokes by providing adequate risk reduction in the primary care setting.
