Background And Purpose:
Mimics comprise a third of patients presenting with an acute stroke. There is limited information on their natural history.
Methods:
We evaluate long term major cardiovascular events (MACE) in stroke mimics in a prospective database from Qatar.
Results:
Between Feb 2014 and Jan 2019, 481 patients (male: 238; female: 243) mean age 57.5 years (±18.0), with 399 (83%) medical mimics and 82 (17%) functional mimics were evaluated. Imaging revealed previous old stroke in 26.6% and small vessel disease in 5%. MACE occurred in 57 (11.9%) and there were 31 deaths (6.4%) with majority of deaths (5.6%) from cardiovascular causes. MACE was significantly higher in patients with previous stroke, p < 0.0001), coronary artery disease, p = 0.002), diabetic, p = 0.01), and hypertensive on admission, p < 0.0001. MACE were also significantly higher in patients where imaging showed a previous stroke, p = 0.006).
Conclusion:
The occurrence of MACE during follow-up suggests that patients with existing vascular disease require aggressive management of vascular risk factors.
