OBJECTIVE: The prevalence of malnutrition in patients with acute ischemic stroke (AIS) can range from 8% to 34%. It has been shown that prognostic nutritional index (PNI) and control nutritional status (CONUT) scores can provide an opportunity to make prognostic predictions in some disease groups. Previous studies have shown a close relationship between malnutrition scores and stroke prognosis. We evaluated the effect of nutritional scores on in-hospital and long-term mortality in AIS patients undergoing endovascular therapy (EVT).

PATIENTS AND METHODS: 219 patients who underwent EVT for the AIS were included in this retrospective design and cross-sectional study. The primary endpoint of the study was accepted as all-cause death including in-hospital death, 1-year death, and 3-years death.

RESULTS: A total of 57 patients died in the hospital. In-hospital mortality rate was higher in the high CONUT group [36 (49.3%), 10 (13.7%), 11 (15.1%), p<0.001]. A total of 78 patients died within one year, and 1-year mortality was higher in the high CONUT group [43 (58.9%), 21 (28.8), 14 (19.2), p<0.001]. At the end of the 3-year follow-up, 90 patients had died, and the 3-year mortality rate was significantly higher in groups with a high CONUT score than in those with a low CONUT score (p<0.001).

CONCLUSIONS: A higher CONUT score, calculated easily by simple scoring with parameters studied from peripheral blood before the EVT procedure, is an independent predictor of in-hospital, 1-year, and 3-years all-cause mortality.
