Andrej Netland Khanevski has looked at the rates of re-admittance to hospital due to recurrent strokes, transient ischemic attacks (TIA) and stroke mimics.
MAIN RESULTS:
- Short- and long-term rates of clinical recurrent events after inciden
- Stroke mimics is more common reason for re-admittance than actual recurrent stroke.
- New admittance after stroke is associated with doubled mortality.

SUMMARY:
Almost 2000 patients admitted with ischemic stroke or TIA at Haukeland University Hospital between 2007 and 2013 are included in Khanevksi’s studies.
(1) Nearly 2% were admitted with a new stroke/TIA within a month of the first event. The risk was higher in patients with large strokes caused by atherosclerosis, as well as in patients with cancer.
(2) The recurrence rates were 5% and 11% at one and five years, respectively. At the end of follow-up in 2016, 14% of the patients had been re-admitted. Older patients with hypertension and prior stroke were at higher risk of new hospitalizations in the long term.
36% of the patients died during follow-up. All-cause mortality was more than doubled in patients who experienced recurrent events.
(3) Stroke mimics were more frequent than recurrent strokes/TIAs, occuring in 19% of the patients during the full follow-up period. The risk was highest the first year after the initial event. Mimics were associated with symptoms such as infections, seizures, dizziness, migraine and syncopes.
