Andrej Netland Khanevski has looked at the rates of re-admittance to hospital due to recurrent strokes, transient ischemic attacks (TIA) and stroke mimics.


  1. Short- and long-term rates of clinical recurrent events after inciden
  2. Stroke mimics is more common reason for re-admittance than actual recurrent stroke.
  3. New admittance after stroke is associated with doubled mortality.

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.
